Splicing screen frame weakening structure and splicing screen

Abstract

The present invention provides a splicing screen frame weakening structure and a display device. The splicing screen frame weakening structure includes a light-transmitting light-transmitting entity, which has a fixed surface for fixing to the frame and a light-emitting surface opposite to the fixed surface. The light-transmitting entity is divided into the inner area facing the frame area and the outer area located on the surface of the edge display area of ​​the display screen; at least a first prism structure is formed at the corresponding position on the inner area of ​​the light-emitting surface, and the light emitted from the edge display area of ​​the display screen Light is incident from the outer area of ​​the light-transmitting entity, and part of the light is refracted by the first prism structure on the light-emitting surface of the light-transmitting entity and then exits from the inner area of ​​the light-emitting surface. The frame weakening structure of the splicing screen provided by the present invention can use the light emitted by the edge display area of ​​the display screen to deflect the light, thereby realizing the optical effect of eliminating or weakening the frame of the splicing screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a splicing screen frame weakening structure and a splicing screen. Background technique [0002] With the rapid development of LCD (Liquid Crystal Display) 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. Due to the limited area of ​​a single LCD screen, in order to realize a large-area display, projection or splicing screens are often used to expand the display area. The weakness of the projection method is that the projected brightness is limited, the resolution is limited, and it is difficult to provide a large-area display continuously and stably for a long time. The screen size increases. [0003] However, since the display area of ​​the liquid crystal display needs to be installed and protected by a frame, when multiple display screens are splice...

AI Technical Summary

Problems solved by technology

Although the above method has a certain weakening effect on the frame of the splicing screen, there are still the following problems: the setting of the transparent plate will increase the thickness of the splicing screen, and the V-shaped groove needs to meet a certain depth to achieve a better weakening effect; The transparent board is arranged as a whole, and the cost is high; in addition, the viewing angle of the light after the V-shaped groove is deflected is small, and the frame will still seriously affect the visual effect at different viewing angles
