A transparent LED screen is like a shutter structure, with gaps between the light strips forming a transparent effect. Compared with traditional LED screens, transparent LED screens greatly reduce the obstruction of sight by structural components, maximize the perspective effect, and ensure sufficient thinness in form. But for transparent LED screens, the real difficulty is to make these tens of thousands of pixels “transparent enough” while maintaining “clear enough”.
So what are the advantages of transparent LED screens, and how to choose transparent LED screens?
What are the advantages of LED transparent screens?
As an advertising medium, transparent LED screens have rapidly occupied the market in recent years, not just to satisfy people’s pursuit of visual effects, but also transparent LED screens have these advantages, such as high permeability, small footprint, and thin and light form.
First of all, transparent LED screens have a transmittance of 50%-90%, which ensures the lighting requirements and viewing angle range of lighting structures such as floors, glass facades, windows, etc., without blocking the line of sight.
Secondly, the main board of the transparent LED screen is thin, takes up almost no space after installation, and does not interfere with other facilities or structures near the glass curtain wall. In addition, the transparent LED screen is simple to operate and highly controllable. It can be controlled wirelessly through remote clusters, and the display content can be changed at any time to ensure that the advertising content is updated in real-time.
How to choose transparent ED screens Size?
Transparent LED screens are divided into front-emitting LEDs and side-emitting LEDs.
Analysis of front light-emitting transparent LED
The front-emitting transparent LED screen uses conventional SMD lamp beads to be mounted on a hollow PCB board, and the driver IC is centrally placed. This LED display is made of conventional components and conventional processes. It is characterized by a simple production process, traditional components, and no bright or dark lines between the light strips.
Pros:
Standard lamp beads for conventional LED displays and can ensure a full 160-degree viewing angle.
Cons:
The hollowing rate is low, the locations where ICs are concentrated are prone to color casts, the cutting is inflexible, and it is difficult to customize.
Analysis of Side-emitting transparent LED
The side-emitting transparent LED screen uses the SMT process to mount the side-emitting lamp beads on the PCB light strip. The SMT process is more difficult than the front luminescence LED display, and it is suitable for glass curtain walls with variable sizes and special-shaped customization.
Pros:
It has a high cut-out rate when viewed at head-on, high brightness, and is easy to customize.
Cons:
The cutouts are different at different viewing angles up and down, and bright and dark lines and blurred screens are prone to appear between the light bars, color casts at left and right viewing angles, and light leakage from behind the screen.
Side-emitting lamp beads are installed on the upper or lower side of the circuit board. Due to the obstruction of the circuit board, only one side of the viewing angle can be guaranteed. There will be obvious color cast when viewed from different angles.
Transparent materials have different refraction effects on the light emitted by LED chips at different locations.
The difference :
The thickness of the front-emitting LED and circuit board parts is 1.6mm, and the light-blocking part is only 1.6mm.
· The shell and the colloid are thick
· The lamp beads are attached to the side of the PCB board
· The lamp wall is completely blocked,
· no light leakage and no light pollution indoors.
The thickness of the side-emitting LED should be at least 1mm, plus the 1.4mm circuit board and the light-blocking part should be at least 2.4mm.
· The shell and colloid are thin
· The lamp beads are attached below the PCB board
· lamp wall is not blocked
· large light leakage and strong indoor light pollution.
Pixel Pitch Choice:
Due to the small size of positive-emitting LEDs, the spacing can be as minimum as 2.0mm, the resolution per unit square area is higher, and the picture is clearer.
The width of the side-emitting LED is 3.5mm, and the minimum pitch is 3.9mm. The resolution per unit square area is limited, and the picture clarity is average.
Low-brightness transparent LED displays are often more suitable for indoors (brightness below 1000 units), and the broadcast image quality is still acceptable. If the indoor light is bright but the brightness of the LED screen is very low, the light brightness will cover the image quality and clarity of the screen, and the playback effect will not be clear. Therefore, Professional LED transparent screen manufacturers like GDHANHENG will recommend higher brightness transparent LED display to customers (brightness above 2500 unit). If you use transparent LED for outdoors, the light is generally stronger during the day, and brightness above 4000 is sufficient.
The smaller the pixel pitch, the higher the pixels and the higher the clarity.
| P2.5 | small areas within 1-5 square meters | with high requirements for clear image quality | relatively expensive prices | low user purchases. |
| P3.91 | small areas within 1-10 square meters | with clear image quality | high price | average user purchases. |
| P7.81 | areas with an area of more than 10 square meters | clear and average picture quality | high cost performance | large user purchases. |
| P10.42 | area of more than 80 square meters | with clear and average picture quality | high cost performance | large user purchases. |
| P15.625 | areas of more than 100 square meters | with average image quality | low price | relatively average user purchases. |
| P20 | area of more than 200 square meters | with average picture quality | low price | relatively average user acquisition volume. |
| P25 | area of more than 300 square meters | with average picture quality | low price | relatively average user purchase volume. |
| P31.25 | area of more than 400 square meters | with average image quality | low price | low user acquisition volume. |
