1. What is Transparent LED Display?
Transparent LED display is a display technology that directly encapsulates micro-LED pixels on a transparent substrate (such as glass or PET film). It can present dynamic videos and graphics without blocking background light, achieving a transmittance of up to 50%-95%, and remains clearly visible in the sun.
It combines the high brightness and dynamic performance of traditional LED screens with the transparent visual effect of glass, providing a new digital solution for commercial windows, building curtain walls, exhibition displays, and other scenes.
Based on the installation methods, transparent LED displays can be categorized into:
● Glass panel type: Transparent glass LED display features a glass-LED-glass sandwich structure, suitable for permanent building curtain walls.
● Self-adhesive film type: The film substrate of the transparent LED film display screen can be attached to the existing glass, suitable for short-term or temporary activities.
● Grid/net type: LED nodes in transparent grille LED display are scattered on the grid lines, with ultra-high transmittance and lightweight, suitable for large-span installation.
2. How Does It Work
Transparent LED display is an innovative display device that combines traditional LED display technology with transparent materials. Its unique design enables it to present high-definition images and video content without affecting the background field of view.
Working principle of Transparent LED Screen Display
① Structural composition
A transparent LED screen display is mainly composed of the following parts:
● Transparent substrate
Transparent LED screens usually adopt a “sandwich” structure of double-layer glass or glass + PET film. The substrate not only supports LED lamp beads, but also needs to ensure a transmittance of up to 70%-95%, and has a certain mechanical strength and safety.
● LED pixel array
LED chips are glued on the surface of the substrate with a fixed pixel pitch (such as P3.9, P7.8, etc.). The smaller the pitch, the higher the resolution, but the transmittance is slightly reduced; the larger the pitch, the better the light transmission effect, but the ability to display details is reduced.
● Driving and control circuit
Micro LED driver IC and sending card are arranged on the edge of the screen, and video signals and power are transmitted to each module through thin cables or flexible flat cables. Multiplexing technology is used to reduce wiring and realize precise PWM dimming and color control of LED point by point.
② Display principle
When current passes through the LED chip, electrons and holes recombine to release photons, emitting red, green and blue primary colors. The brightness and color mixing are controlled by PWM technology to form a full-color image. Because there are gaps between LED lamp beads and they are installed on a transparent substrate, the screen as a whole has a high light transmittance, and the audience can see the content on the screen and the scenery behind it at the same time.
In addition, some advanced products use a shutter-style or grille-style hollow design. By adding a light-guiding structure behind or on the side of the LED, the light transmittance and visual effect are further improved, while the heat dissipation performance is optimized to ensure high brightness and long-term stable operation.
③ Relationship between transmittance and pixel pitch
The transmittance of LED transparent screen displays is usually between 70% and 95%, depending on the pixel pitch and arrangement of the LED lamp beads. The larger the pixel pitch, the larger the gap between the LED lamp beads, the higher the transmittance, but the displayed resolution is correspondingly reduced; conversely, the smaller the pixel pitch, the more delicate the display effect, but the transmittance will decrease.
- Fine pitch (P2.6–P3.9): suitable for close viewing (≤3 m), high resolution, and transmittance of about 70%–75%.
- Medium pitch (P5.2–P6.67): suitable for medium-distance viewing (3–6 m), with a transmittance of about 80%–85%.
- Coarse pitch (P8.0–P10.4): suitable for long-distance viewing (>6 m), with a transmittance of more than 90%.
Reasonable selection of pitch can achieve the expected transparent effect while ensuring the details of the picture.
④ Drive and control technology
The drive circuit needs to complete a high-power power supply and high-frequency signal transmission within the extremely thin panel thickness. Common practices include:
- Edge drive: Place the driver IC on the screen border and connect it through multiple thin cables;
- Integrated drive module: Fit the ultra-thin driver board on the back of the panel to achieve modular splicing and fast maintenance.
Modern transparent LED screen also support input signals through multiple methods such as optical fiber, HDMI, and network streaming, and can be combined with software such as NovaLCT and V-Can to monitor and adjust parameters in real time to improve installation efficiency and later operation and maintenance experience.
⑤ Optical properties and viewing angle
In order to adapt to different indoor and outdoor lighting environments, transparent LED screens ensure readability through high brightness and wide viewing angle design:
High brightness: outdoor models can reach 5,000–7,500 nits, ensuring clear visibility under direct sunlight; indoor models are commonly 1,500–3,000 nits, taking into account both energy saving and image quality.
Wide viewing angle: ≥140° horizontal/vertical viewing angle ensures that the color is not distorted or cast when multiple people watch from different angles at the same time.
3. Key Features of LED Transparent Screen
Transparent LED display is an innovative device combining high-brightness LED technology with transparent substrates. It is widely used in commercial display, architectural decoration, stage performance and other fields. The following are its main features:
Feature 1. High light transmittance, retaining the lighting field of view
The light transmittance of transparent LED display is usually between 50% and 95%, depending on the pixel pitch and structural design. This high light transmittance makes the screen almost “invisible” when not working, and does not affect the natural lighting and field of view of the building.
Feature 2. Lightweight design, easy installation
The panel thickness of a transparent LED display is usually only about 10mm, lightweight and easy to install. This design reduces the burden on the building structure and is suitable for various installation environments, such as glass curtain walls, windows, etc.
Feature 3. Energy saving and environmental protection, reducing operating costs
Transparent LED display uses an efficient LED light source, low energy consumption, and a significant energy-saving effect. Compared with traditional LED displays, the energy consumption of transparent LED displays can be reduced by more than 30%, which helps reduce operating costs.
Feature 4. High brightness and wide viewing angle to ensure visibility
The transparent LED display has high brightness (up to 4500 to 6000 nits) and a wide viewing angle (about 140°), which can clearly display content even in strong light environments, ensuring the visibility of information.
Feature 5. Modular design, easy maintenance
The transparent LED display adopts a modular design, which is easy to install and maintain. When replacement or repair is required, only the corresponding module needs to be replaced, which reduces maintenance costs and time.
4. Traditional LED Screen vs Transparent LED Display
Transparent LED display and traditional LED screen each offer unique advantages and are suited to different applications. Here’s a comparative overview to help you determine which technology best fits your needs:
| Feature | Transparent LED Displays | Traditional LED Screens |
