Transparent display module and manufacture method thereof

Abstract

The invention discloses a transparent display module, including a first photic layer, a second photic layer and a middle layer arranged between the first photic layer and the second photic layer. Thefirst surface of the second photic layer is provided with a plurality of lamp beads, and the first surface of the second photic layer is provided with a first conducting circuit electrically connectedwith the lamp beads, and a second conducting circuit used for controlling lamp beads to display and connected with an external controller; and the second conducting circuit is electrically connectedwith the first conducting circuit, and controls on-off of the first conducting circuit, and the second conducting circuit is connected with an external power and the controller through connection terminals arranged on the second photic layer. According to the transparent display module, the integration level is high, the structure is simple, a product is stable, responsibility is high, the servicelife is long, and assembly is convenient.

Description

technical field [0001] The invention relates to a display device, in particular to a transparent display module and a manufacturing method thereof. Background technique [0002] With the development of LED technology, there are more and more products using LED technology. Conventional LED displays have high resolution and can be assembled into large-format display devices, so they are widely used in outdoor large-screen displays. Traditional outdoor LED screens are usually opaque, and are installed outside the outdoor building by hanging, which seriously affects the lighting of the building. [0003] In order to overcome the above-mentioned shortcomings of traditional LED screens, transparent LED screens emerged as the times require. Existing transparent LED displays are usually provided with LED lamp beads on conductive glass and synthesized by lamination technology. However, the existing transparent LED display uses a laser laser line on the conductive glass, pastes LED...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the limitation of the material of FPC itself, FPC is not resistant to UV, and its weather resistance is not good. It is easy to become brittle when used outdoors and has a short service life;

[0006] 2. When the FPC is connected to the PCB, the FPC connector is used. The connection is not firm, easy to loosen and fall off, which seriously affects the stability and reliability of the product; the improvement method usually used in the industry is to use yellow glue after connecting the FPC. It is fixed, but it is still unstable, and the tearing of a slightly larger external force will cause the FPC to deform and cause line interruption;

[0007] 3. The external power supply supplies power to the lamp beads through the PCB board and FPC, and the overall power supply will be consumed and weakened, affecting the brightness of the product;

[0008] 4. The PCB board is affected by the density of lamp beads in the circuit, and its size is uncertain, which affects the size of the sub-frame of the product
