A lcd splicing system that eliminates the display frame

Abstract

The present invention relates to the field of display devices, in particular to an LCD splicing system that eliminates display frames. It includes several LCD panels that are spliced ​​into a splicing screen, and also includes an optical system and a light emitting device. The optical system is arranged on the surface of the LCD panel. The frame area of ​​the LCD panel is divided into an inner area and an outer area. The edge display area of ​​the LCD panel The outgoing light is vertically incident on the optical system, enlarged and expanded to the inner area of ​​the frame area by the optical system, and the light emitted by the light emitting device is vertically incident on the optical system, enlarged and expanded to the outer area of ​​the frame area by the optical system. The invention can eliminate the frame between the LCD panels, and the LCD panel after the frame is eliminated has good display effect, simple structure, low splicing difficulty and high production efficiency.

[0002] With the rapid development of large-size LCD panels, LCD displays have gradually become the mainstream of display technology due to their advantages such as ultra-thin, light weight, no radiation, and stable performance. Currently, large-size LCDs can be 80 inches to 100 inches, but It is still difficult to meet the needs of some occasions (such as monitoring, scheduling, etc.), and the yield rate of its super-large LCD panel is difficult to guarantee

[0003] Due to the needs of the surrounding circuit wiring and packaging, the existing LCD panel inevitably has an undisplayable area around the display image. This undisplayable difference is called a frame. The existence of the frame causes the screen to be divided during LCD splicing and destroys the image. continuity and integrity, which seriously affects the splicing effect

At present, many LCD panel manufacturers have been working hard to reduce the frame width of LCD panels, but they still cannot achieve zero frame and realize seamless splicing in the true sense.
