Chapter 1: The Current Situation and Advantages of LED Displays LED displays are ubiquitous in modern times. For example, they appear in our mobile phones, televisions, and so on. Although most devices now use the more advanced OLED display technology, LEDs are still used in many devices, and they have the advantage of not suffering from burn-in.
Chapter 2: The Optical Primary Colors and the Technological Limitations of LEDs Let's start by getting acquainted with the three optical primary colors. RGB—that is, red, green, and blue primary colors—combine to produce the range of colors seen on a display. When all three primary colors are added together, the result is white. By continuously reducing the size of each LED, the quality of the image improves. However, due to limitations in material manufacturing, modern technology is not yet capable of producing the ideal LED size. To achieve 4K resolution quality, the manufacturing size of an LED would need to be about 0.3 millimeters, a size that is difficult to mass produce. As the saying goes, "after traversing rugged mountains and vast waters there seems to be no way out, yet a welcoming village appears in the midst of the dark forest."
Chapter 3: The Basic Principles of Transitioning from Black-and-White to Color Displays We can use a miniature green emitter to replace the LED's light emission and employ a unified light source—using a white LED as the backlight—to establish the basic principles of the display. At this stage, only black and white can be displayed: when the backlight is on, white is produced; when the backlight is off, black is produced. But isn't that just like the era of black-and-white screens? Hold on, there's more. We can achieve color display by individually controlling the light intensity of each green emitter. Behind each green emitter, two polarizers are arranged, along with a material capable of changing its optical angle. Before diving deeper into this new configuration, it is necessary to briefly review some fundamental physics of light. Light has perpendicular electric and magnetic fields, and its direction of propagation is perpendicular to both fields. In fact, the electric and magnetic fields exist in that direction of propagation; for simplicity, we will only show the electric field. When we add a vertical polarizer, it allows only the vertically polarized light to pass, blocking light polarized in other directions.
Chapter 4: Light Intensity Control Mechanisms and RGB Pixel Synthesis
Now, let's examine the mechanism for controlling light intensity. When light passes through the vertical polarizer, only vertical light is transmitted. Then it reaches a device known as an angle rotator. Note that the angle rotator is only as large as a subpixel. When it receives a rotation signal, it rotates the vertically polarized light to the desired angle. If the rotation angle is 90 degrees, the light can perfectly pass through the subsequent horizontal polarizer, and the display works normally. If the light rotates by less than 90 degrees, the horizontal polarizer blocks some of the light, reducing the display's brightness. If the rotation angle is 0 degrees, all of the vertically polarized light will be blocked by the horizontal polarizer, and nothing is displayed. This is the method used to control the intensity through filtering. Three control units work together to control a single RGB pixel. By adjusting the rotation angle of the light, any pixel color can be achieved; for instance, to display cyan, we simply need to block the red light, and to display yellow, we block the blue light. Through this clever arrangement, a complete display system is built—this is the basic design principle behind LED televisions.
Chapter 5: Liquid Crystal Materials and the Physical Mechanism of Light Rotation Now, returning to the somewhat unusual angle rotator that we mentioned only briefly earlier, let's see how it achieves different optical rotation angles. The answer lies in the material of the rotator—liquid crystals. Indeed, that is why they are called LCD TVs. Usually, liquid crystals are in a 90-degree twisted state, as shown here. When an electric field is applied, they rotate, which in turn causes the light to rotate. But what causes the light itself to rotate within the liquid crystals? For clarity, let's consider linearly polarized light as being composed of two circularly polarized components, like this: Note that the purple light rotates clockwise, while the cyan light rotates counterclockwise. When passing through the twisted liquid crystals, their relative speeds differ—specifically, the cyan light waves slow down when traversing the twisted liquid crystal. This speed difference causes the light to undergo a 90-degree phase shift, which changes the composite angle of the output light—this is the rotation angle. If the liquid crystal were not twisted, the two kinds of light would have no phase shift because their speeds would be identical. No speed difference means no phase shift. This is what happens when polarized light passes through the angle rotator.
Chapter 6: Display Optimization and the Comparison Between LED and OLED Technologies However, even at this stage, the design is incomplete. Next, let's examine a mobile phone screen under a microscope. When an LED display is magnified, many colored blocks can be seen—these are the subpixels of the display. Notice the transition between two colors; the boundary is very apparent and somewhat harsh. This is because some pixels are brighter than others, and the LED backlight provides uneven illumination. Placing a diffusion plate in front of the LED light source causes the light to scatter evenly and spread gently. Although this makes the lighting more even and softer, it comes with a downside: the diffusion plate disperses the light in all directions, which inevitably weakens the brightness. The solution to this problem is to add a prism in front of the diffusion plate. The prism focuses the light in a particular direction, preventing it from scattering everywhere, which solves the issue. Yet, there is a minor flaw: if you want to display a small white dot on a black screen, the entire LED backlight must be fully turned on. This increases power consumption and prevents the LED from displaying a perfectly pure black interface. OLED, on the other hand, can solve this problem because its pixels emit light independently, although OLEDs have the disadvantage of potentially suffering from burn-in.
Conclusion: The Genius and Insights of LED Display Technology This concludes the explanation of the basic display principle of LED screens. After understanding this, one cannot help but admire the genius who invented it—truly a mastermind.

COB (Chip on Board) is also a kind of LED display packaging technology. Unlike traditional LED screens, COB technology involves mounting multiple LED chips directly onto a circuit board, eliminating the need for individual packaging. This consolidation enhances brightness, reduces heat emission, and enables a more seamless display.
Advantages Over Traditional LED Screens
COB LED screens outshine their counterparts in terms of performance. The absence of gaps between LED chips ensures uniform lighting, preventing issues like the “screen door effect.” Additionally, COB screens offer better color accuracy and higher contrast ratios.
Advantages of COB LED Screen
Owing to the diminutive size of the LED chip, COB offers a significantly heightened packing density when juxtaposed with Surface Mount Device (SMD) technology. This manifests as a more compressed array, ensuring enhanced uniformity, heightened intensity even in proximity, and superior heat dissipation, bolstering stability, reliability, and longevity. The encapsulation of COB chip and pin legs augments airtightness, fortifying resistance against external forces, yielding a seamless, polished surface. Moreover, COB boasts heightened resistance to moisture, ElectroStatic Discharge (ESD), damages, and dust, flaunting an IP65 surface protection rating.
Stable technological process. As shown above, SMDs need to use reflow soldering. When the soldering paste reaches a temperature of 240°c the epoxy resin weight loss rate is 80% which easily causes the glue to separate from the LED cup, but in the case of COB technology there is no reflow soldering process so it is more stable.
A Closer Look: Pixel Pitch Precision Pixel pitch, denoting the proximity of pixels on a display, undergoes refinement with COB LED technology. The smaller pixel pitch translates to increased pixel density, yielding superior resolution. This reduction in pitch ensures clarity even for viewers in close proximity to the display.
Illuminating the Dark: Light Efficiency Efficient heat dissipation and low light attenuation hallmark COB LED technology. Direct dispensing of the COB chip onto the PCB expands the heat dissipation area, surpassing the SMD counterpart in attenuation. SMD's heat dissipation emanates from the bottom of its anchoring.
Expanding Horizons: Viewing Angles The small pitch technology within COB bestows a broader viewing angle, transcending indoor and outdoor scenarios with heightened brightness.
Indomitable Resilience COB stands resilient against collisions, impervious to the impact of Oil, Damp, Water, Dust, Oxidation, and dust.
High Contrast Ratio The contrast ratio, a pivotal metric for LED displays, achieves new heights with COB, boasting a static contrast ratio between 15,000 to 20,000 and a dynamic contrast ratio reaching 100,000.
The Green Epoch: Energy Efficiency In the realm of energy efficiency, COB surges ahead of SMD, a critical factor in the operational cost of expansive displays subjected to prolonged usage.
The Shadows of COB LED Display: Unveiling Drawbacks
Crafting Challenges The encapsulation of an LED display within COB mandates a defect-free lamp before refilling. Unlike SMD packaging, individual bulb replacement is unfeasible, intensifying the stringency of the packaging process.
Maintenance Dilemma Traditional SMD packaging allows for unit board disassembly after a single LED soldering repair. In contrast, COB products complicate maintenance, impacting surrounding lamps. Despite enhanced protection, a discernible dead light rate persists, necessitating unit board replacements. Although COB panels incur higher costs, their failure probability is substantially lower, making the maintenance cost comparable to SMD. As COB manufacturing costs decline, the trajectory suggests COB LED screens may soon eclipse SMDs in cost-effectiveness.

Advantages of COB LED screen Due to the small size of the LED chip, COB offers significantly increased packaging density compared to Surface Mount Device (SMD) technology. This results in a more compact package, which provides increased uniformity, increased intensity even at close range, and excellent heat dissipation, reinforcing stability, reliability, and long life. The encapsulation of COB chips and pins increases air tightness, reinforcing resistance to external forces, resulting in a seamless, polished surface. In addition, COB is highly resistant to moisture, electrostatic discharge (ESD), damage, and dust, and has an IP65 surface protection rating.
Stable technological process. As shown above, SMDs need to use reflow soldering. When the solder paste temperature reaches 240°C, the weight loss of epoxy resin is 80%, which makes the adhesive easily peel off from the LED cup, but COB technology does not have a reflow soldering process, so it is more stable.
In detail: Pixel Pitch Precision The pixel pitch, which indicates the closeness of the pixels on the screen, is refined with COB LED technology. The smaller pixel pitch results in a higher pixel density, resulting in excellent resolution. This pitch reduction ensures clarity even for viewers close to the display.
Lighting up the darkness: Light efficiency Efficient heat dissipation and low light attenuation are the hallmarks of COB LED technology. The direct application of the COB chip to the PCB increases the heat dissipation area, surpassing the SMD equivalent in attenuation. The heat dissipation of the SMD comes from the bottom of the fixture.
Expanding horizons: perspectives COB's short-throw technology provides a wider viewing angle that surpasses indoor and outdoor scenarios with increased brightness.

The Green Era: Energy Efficiency COB outperforms SMD in terms of energy efficiency, which is a critical factor in the operating costs of large displays exposed to prolonged use.
Shadows of COB LED Display: Revealing Disadvantages Crafting challenges Encapsulating the LED display within the COB requires a defect-free lamp before repackaging. Unlike SMD packaging, individual bulb replacement is not feasible, which increases the rigor of the packaging process.
Maintenance dilemma Traditional SMD packaging allows the unit board to be disassembled after soldering a single LED. In contrast, COB products make maintenance difficult and affect the surrounding lights. Despite the increased protection, the rate of dead light is still noticeable, which requires replacing the unit board. Although the cost of COB panels is higher, their probability of failure is significantly lower, so the maintenance cost is comparable to SMD. As COB manufacturing costs decrease, the trajectory suggests that COB LED screens may soon eclipse SMDs in terms of cost-effectiveness.

Whether it is commercial display, stage performance, or architectural decoration, transparent LED walls have been favored by more and more industries with their high-definition perspective effect, fashionable sense of technology and strong visual impact. Compared with traditional LED display screens, transparent LED screens can not only maintain the transparency of the space, but also achieve shocking dynamic content presentation, bringing unlimited possibilities for brand promotion and visual art. With the continuous advancement of intelligent display technology, the application scope of transparent LED walls is further expanding, covering shopping mall windows, exhibition halls, conference centers and other fields.
So, what are the advantages of transparent LED walls? Why is it so popular? This article will explore the core features of transparent LED walls and analyze their outstanding performance in different scenarios.
Transparent LED wall is a high-tech display device that uses special LED lamp beads and light-transmitting design to achieve 60% to 90% transparency. It can maintain a clear view while playing content, and perfectly integrates with glass curtain walls or windows. It is widely used in scenes such as shopping mall windows, exhibition displays and stage backgrounds.
This screen is not only thin and beautiful, but also easy to install and energy-efficient. Its modular design supports custom sizes and is compatible with remote control systems for easy content updates. With its unique visual effects and practicality, transparent LED walls are becoming a new trend in commercial displays and advertising.
1.2 Advantages of transparent LED walls:
High transparency effect: Due to the different dot spacing of the LED screen, the transmittance can be between 50-90%. The perspective effect allows the glass to retain the function of lighting perspective. The existence of the LED lights is almost invisible from a distance, so the lighting of the glass curtain wall is not affected.
Small space occupation and light weight: The thickness of the screen mainboard is only 10mm. After the transparent LED wall is installed, it takes up almost no space and does not hinder other facilities or structures near the glass curtain wall. The transparent LED wall weighs only 14kg/㎡. After being installed on the glass curtain wall, the load requirements of the glass curtain wall are changed very little.
Only a simple steel frame structure is required, saving a lot of costs: This product is light in weight, easy to install, does not require complex supporting steel structures, and can save a lot of installation costs.
Easy and quick maintenance: Indoor maintenance is quick and safe, saving manpower and material resources.
Save building lighting costs: If an LED glass curtain wall display (transparent screen) is installed, a large part of the exterior wall lighting fixtures can be saved. At the same time, the LED screen is more attractive, which can save costs and have advertising benefits.
Energy saving and environmental protection: It consumes little power, with an average power consumption of less than 280W/㎡, and does not require traditional refrigeration systems and air conditioning for heat dissipation.
2. Classification of transparent LED walls
According to the light-emitting mode of LED lamp beads, transparent LED walls are mainly divided into two types: side-emitting LED and front-emitting LED. Different light-emitting modes affect the light transmittance, brightness and application scenarios of transparent LED walls. Let's introduce the characteristics of these two types in detail.
2.1 Side-lit transparent LED wall
The side-emitting transparent LED wall adopts a side-emitting design, that is, the LED lamp beads are installed on the side of the PCB board instead of facing directly to the front. This design prevents the lamp beads from blocking the line of sight and improves the overall transparency. The light transmittance can usually reach 70% to 90%, which is suitable for occasions with high transparency requirements, such as shopping mall windows, exhibition hall glass curtain walls, and car 4S stores.
2.1.1 Advantages:
High transparency: The lamp beads emit light sideways, leaving a large gap between LED modules to maximize light transmittance.
Strong visual impact: the picture seems to be suspended on the glass, without affecting the lighting and perspective effects of the environment behind it.
Beautiful and thin: The module is thinner and suitable for mounting on glass curtain walls without destroying the original style of the building.
2.1.2 Disadvantages:
The brightness is relatively low: Since the lamp beads emit light sideways, the overall brightness is slightly lower than that of front-emitting LEDs, and is not suitable for outdoor environments with direct strong light.
Limited viewing angles: Since the light is projected from the side, brightness may fall off when viewing at certain angles.
2.2 Front-lit transparent LED wall
The light beads of the front-emitting transparent LED wall directly emit light towards the audience, ensuring higher brightness and clearer display effects. This type of screen is usually used in outdoor advertising, stage performances, glass curtain walls of large shopping malls, etc., and can still maintain excellent visibility in strong light environments.
2.2.1 Advantages:
High brightness: Direct light design makes the screen brighter and clearly visible even in the sun.
Strong color expression: The picture is more vivid and delicate, and the display effect is better, suitable for application scenarios that require high-quality pictures.
Wider viewing angle: Whether viewing from the front or side, it can provide good display effects.
2.2.2 Disadvantages:
The light transmittance is relatively low: Since the lamp beads emit light forward and the density of the PCB board is high, the light transmittance is usually between 50% and 70%.
The screen is slightly thicker: Compared with side-emitting LEDs, the installation method of the lamp beads of front-emitting LEDs increases the overall thickness of the module, which may affect the aesthetics of some high-end buildings.
3. Transparent LED Walls Work
Transparent LED wall is a display device that uses LED (light-emitting diode) technology to project light onto transparent materials to generate images, allowing viewers to clearly see the image content from both sides of the screen.
The working principle of the transparent LED wall mainly relies on the combination of LED lamp beads and transparent substrate. The LED lamp beads are arranged in a matrix on a transparent material (such as glass or acrylic), and the brightness and color of each lamp bead are precisely controlled by a controller. When the display is working, the light emitted by the LED lamp beads passes through the transparent substrate to form a bright image, while allowing background light to pass through, maintaining the transparent characteristics of the screen.
The core advantage of the transparent LED wall lies in its unique structural design. The LED beads are embedded between two layers of film: the upper layer is transparent material that allows light to penetrate; the lower layer is reflective, reflecting light back to the audience's eyes. By adjusting the brightness and color combination of the LED, the display can present colorful images and videos. In addition, the transparent LED screen has a wide viewing angle, and the audience can watch from different angles without image distortion or blur.
When displaying dynamic content, the transparent LED wall turns off the LED lamps in the background area of the image and only lights up the lamps in the foreground area, creating a visual effect of the image "floating" in the air while maintaining the transparency of the screen. This technology is widely used in commercial displays, building curtain walls, retail windows and other fields, combining a sense of technology with practicality.
4. Are transparent LED walls worth the investment?
Whether transparent LED walls are worth investing in can be analyzed from the perspectives of technical features, cost-effectiveness, market trends, and potential returns. Here are some key considerations:
4.1 Technical Features
High light transmittance: The biggest advantage of transparent LED walls is their high light transmittance, which allows them to display dynamic content while maintaining the visibility of the background. This feature makes them more visually attractive and suitable for scenes that require both transparency and information display.
Visual effect: Transparent LED walls can present vivid colors and high-contrast images, and have wide viewing angle characteristics, allowing viewers to watch clearly from different angles without distortion.
Energy saving and environmental protection: Compared with traditional display screens, transparent LED walls have lower power consumption and a modular design, which makes them easy to maintain and upgrade, and their long-term use costs are relatively low.
4.2 Cost-effectiveness
Initial investment: Transparent LED walls are expensive, especially for high-resolution, large-size screens. You need to decide on the investment scale based on your budget.
Operating costs: Although LED technology itself is energy-efficient, long-term use still requires consideration of electricity costs, maintenance costs, and the cost of content updates.
Service life: High-quality transparent LED walls usually have a long service life and can operate stably for many years, reducing replacement frequency and long-term costs.
4.3 Market Trends
Technological development: Transparent LED technology is constantly improving, with resolution, brightness and color performance gradually improving, while costs are gradually decreasing. If your budget is limited, you can consider waiting for the technology to mature further.

Selecting the right transparent LED wall requires a detailed evaluation of several key aspects to ensure it meets specific needs and provides the best display effect.
6.1 Transparency
Transparency range: The transparency of transparent LED walls are usually between 50% and 90%. High transparency (such as 80%-90%) is suitable for scenes that need to maintain background visibility, such as window displays or building curtain walls; medium transparency (such as 50%-70%) is suitable for scenes that require higher display effects, such as stage design or exhibition displays.
6.2 Available visibility and brightness levels
Brightness level: Select the appropriate brightness according to the installation environment:
Indoor: 500-1500 nits, suitable for low-light scenes.
Outdoor: 5000 nits or more to cope with strong light environments and ensure that content is clearly visible.
Visibility: Choose a screen with a high refresh rate (≥1920Hz) and high grayscale level (≥16bit) to ensure smooth and flicker-free images, suitable for shooting and dynamic content display.
6.3 Pixel Pitch and Resolution
Pixel pitch: The smaller the pixel pitch, the higher the resolution and the clearer the display effect, but the higher the cost.
Resolution: The higher the resolution, the finer the image. Calculate the required resolution based on screen size and viewing distance to ensure that the content is clearly visible.
6.4 Aspect Ratio and Screen Size
Aspect ratio: Common aspect ratios are 16:9 or 4:3, and special ratios can also be customized according to needs. Choose an aspect ratio that matches the content to avoid image distortion.
Screen size: Determine the screen size based on the installation space and viewing distance. Large screens are suitable for long-distance viewing, while small screens are suitable for close-up display. Also consider the screen weight and installation feasibility.
6.5 How to install it?
Fixed installation: Suitable for long-term use scenarios, such as building curtain walls or windows. Ensure that the installation structure is stable and consider the load-bearing and windproof capabilities.
Mobile installation: For temporary events or stage designs, choose a lightweight, easily removable screen.
Hanging or floor-standing: Choose the appropriate installation method based on the space layout to ensure the screen is stable and beautiful.
Installation environment: Consider environmental factors (such as temperature, humidity, and waterproof level) and choose a screen suitable for indoor or outdoor use.

In line with the developing trends of the Mini/Micro LED, COB packaging technology, with the advantages of solid protection, high density, high contrast, fewer broken LEDs, and long lifespan, highly improved the reliability of fine-pitch screens. After 10 years of industry research and technology development, the increasingly mature COB packaging has been employed more extensively. Accordingly, the leading LED display manufacturers have focused on developing and applying COB technology. However, the packaging process and accuracy of materials, such as LED chips and driver ICs, give rise to the problem of brightness and color differences within and between modules, as well as the non-linear response of high and low brightness, seriously affecting the perfect display of the COB screen. Colorlight, with more than 10 years of R&D investment in calibration technology, has accumulated rich industry experience and developed a scientific-grade calibration solution, unlocking the full potential of LED displays and achieving a perfect display effect.

Features
Scientific Grade Calibration Camera
CCM6000, the self-developed scientific-grade calibration camera, uses the CIE1931-XYZ filter to accurately simulate the human eyes' perception of brightness and color. Equipped with a 16-bit high-precision sensor and constant temperature refrigeration system, the camera can accurately and steadily capture each LED's brightness and chromaticity. Meanwhile, with software algorithm optimization for COB screens, it can effectively eliminate the non-uniformity within modules and color blocks between modules.
Low Brightness Calibration
A minimum of 0.01 nit ultra-low brightness can be captured with precision and stability, realizing low brightness calibration and eliminating color blocks and color spots at low grayscale.
Multi-grayscale Calibration
Due to the poor display linearity of some COB screens and inconsistent linear response between LEDs or modules, single-level calibration cannot simultaneously enhance the display under high brightness and low grayscale. Colorlight multi-grayscale calibration technology supports calibrating multiple gray levels, which can eliminate color blocks and spots under high brightness and low grayscale, ensuring the uniformity of each gray level.
High Efficiency
CCM6000 has an ultra-high resolution of 60 million pixels. 3840×2160 LEDs can be captured without moving the camera. Moreover, it uses USB 3.0 as the data transfer port with a transmission speed of up to 2.5 GHz. Therefore, the CCM6000 significantly improves the calibration efficiency of COB screens.
Infi-bit Technology
The Colorlight Infi-bit technology greatly expands the display grayscale and improves the contrast ratio, resulting in a smoother image with richer details. As a result, the calibration accuracy and effects, especially the low grayscale calibration, are all remarkably enhanced. Moreover, the improved grayscale also makes it possible to develop and apply the technology of grayscale refinement.
Grayscale Refinement Technology
With the high-precision colorimeter and software algorithms, each grayscale is accurately measured and calibrated, effectively solving the problems of grayscale color cast, inconsistent linear response, Gamma inaccuracy, color temperature deviation, etc.
