Light guiding module and seamless splice screen

Abstract

The present invention provides a light guiding module. The light guiding module comprises a plurality of light guiding bars which has a coplanar bottom surface being a light incident surface. The light guiding module comprises a third area, a part of the light guiding bars of the third area have a third top surface being a light emitting surface, a plurality of inclined angles are formed between extension directions of a part of the light guiding bars arranged at the third area from the bottom surface to the third top surface and the bottom surface, the part of the light guiding bars arrangedat the third area are arranged in a first direction, projection of the part of the light guiding bars arranged on the third area on the bottom surface is a first length, and the first length is extended outwards from the bottom surface of the light guiding bars arranged at the third area for a first distance. The light guiding module can conduct images of edge positions of the display screen to the light emitting surface of the light guiding module for emission to shield frames of the display screen so as to eliminate the splicing seam of the display screen. The present invention further provides a seamless splice screen.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a light guide module and a seamless splicing screen. Background technique [0002] With the continuous development of the display technology, the application occasions of the display are more and more extensive. Not only for TV, monitor, industrial display, medical display, but also more and more used in public display occasions. In public display applications, it is generally required that the display has a larger display area to meet the requirements of people watching from a long distance and displaying a large amount of information. But as far as the current development status of the display is concerned, the conventional size is 32 inches to 55 inches. If displays in this size range are used for public display, multi-screen splicing is required. [0003] When multiple screens are spliced ​​together, the pre-existing borders of each display border each other to form a spl...

Problems solved by technology

For example, patents CN 104464536A and CN 104181715 A disclose the method of enlarging the screen, but the above method can only have a good effect on eliminating the edge of a single screen. When it comes to splicing multiple screens, it is actually necessary to consider the assembly tolerance of the screen, The expansion gap between the screen and the cover plate cannot really achieve the effect of "zero seam"
