Technical principle and cabinet structure of LED transparent screen

What is LED transparent screen? Transparent LED display means that the LED display has the characteristics of light-transmitting glass, the transparency is between 50% and 90%, and the thickness of the display panel is only about 10 mm. Its high transparency and its special material, structure and installation method closely related.

The principle of LED transparent screen technology is a microscopic innovation of LED display screens. It improves the patch manufacturing technology, lamp bead packaging and control system, and adds a hollow design structure. The design of this display technology greatly reduces the blockage of structural components to the line of sight. Maximized the perspective effect.

Due to the particularity of the project, there are more customization requirements. Under the premise of ensuring product quality and display performance, the transparent screen cabinet adopts a simplified, frameless design, and reduces the width of the cabinet keel and the number of light bars to maximize the effect of transparency. Installed behind the glass and close to the glass, the unit size can be customized according to the size of the glass, which has little effect on the light transmittance of the glass curtain wall and is easy to install and maintain.

In the design of the LED transparent screen advertising content screen, the unnecessary background color can be removed and replaced with black, and only the content that needs to be expressed is displayed. The black part does not emit light during playback. The audience stands at an ideal distance to watch, and the picture is like hanging on on the glass.


The cabinet structure of LED transparent screen

1. Mask: one is to accumulate wavelengths to make the color uniform, and the eyes look less different, and the other is to protect the lamp beads

2. LED transparent module: It mainly includes PCB board and LED lamp beads, and the main display parts.

3. Cabinet body: it is a support, and other modules and power supplies are supported on it. It is made of die-cast aluminum or aluminum profile, which is strong and durable, and the splicing is not deformed.

4.HUB board: As a connection platform, it is possible for the power supply, receiving card, and modules to coordinate together.

5. Power supply: It is the heart of the cabinet, which converts the external power supply into the power of the cabinet itself.

6. The receiving card is responsible for receiving external signals and processing the "brain".

7. If there are one line in the cabinet, it is the blood vessel of the LED transparent screen box to maintain the operation of the cabinet.

8. The signal connection line and power supply line outside the cabinet allow external signals and power to enter the cabinet.
