【Detailed ways】

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

As shown in Figures 1-2, the utility model includes a transparent display module 10, a signal processing transmitting card 20 and a thin transparent panel 30, and the display screen is powered by an external power supply. The display screen can be spliced to form a display screen by sequentially bonding a plurality of transparent display modules 10 on the thin transparent panel 30 with transparent self-adhesive glue according to the actual usage. Wherein the thin transparent panel 30 can be flat glass on the glass window or curved glass or flexible transparent adhesive film, and a PET film is arranged on the thin transparent panel 30, and between the thin transparent panel 30 and the PET film It is coated with an optically clear adhesive (OCA) that can resist UV and high temperature, so that the PET film can be attached to the thin transparent panel 30 for a long time. In addition, the PET film is made of high-quality optical materials, which has strong durability and is protected by natural light. , UV, temperature or LED luminous effects are small. This setting makes the display screen omit the traditional box structure, and no longer needs to work on the outer wall, and can be installed indoors. The wall glass window is regarded as a thin transparent panel 30, which is directly installed on the inner surface or outer surface of the glass window during installation. on the surface and allow 90% of the light to pass through, or stick to the wall as well as the ceiling and floor.

The weight of the entire display screen is greatly reduced due to the absence of a supporting and fixed metal box. At the same time, the thickness of the LED thin-film transparent display screen is very thin, only 1mm thick, making installation and maintenance very safe and easy, even if there is only one person It can also be installed and removed quickly. At the same time, in addition to on-site gluing during installation, the self-adhesive LED film of the 3M optical adhesive system can also be pre-set on the transparent display module 10, which has high adhesive strength and durability, and does not affect light transmission. Effect. At the same time, because the display screen is installed indoors, the screen can avoid the influence of long-term temperature changes, UV, unstable climate and harmful substances, and avoid the sun and rain, because its indoor application also increases the stability and life of the screen.
