Gap eliminating device and seamless splicing display device

Abstract

The invention provides a gap eliminating device which comprises a first optical module arranged in front of a display area and a second optical module arranged in front of a frame area and corresponding to the first optical module. The first optical module and the second optical module are consistent to the frame area in width and comprise multiple first defection parts. The light emergence faces of the first defection parts are columnar faces. The gap eliminating device further comprises a first optical module arranged in front of the display area and a fourth optical module arranged in front of the frame area and corresponding to the third optical module. The widths of the third optical module and the fourth optical module are consistent to the total width of an adjacent splicing frame area, and the third optical module and the fourth optical module comprise multiple second defection part. The light emergence faces of the defection parts are planes. By adopting the gap eliminating device, smooth transition between emergence light of the frame area and emergence light of the display area can be achieved, and the display effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of display screen splicing, in particular to a seam elimination device and a seamless splicing display device including the seam elimination device. Background technique [0002] In recent years, the large-screen splicing display market is still developing strongly, and it plays an important role in many industries and places such as electric power, coal, finance, transportation, and security. In the large-screen splicing display, LCD (Liquid Crystal Display) splicing display is favored by many merchants and customers due to its significant advantages such as light and thin size, low cost, large viewing angle, and low power consumption. However, due to process wiring and other reasons, the edge frame of the LCD is unavoidable, resulting in a seam of at least 5.5mm or more, which makes the screen divided and cannot be connected, which seriously affects the splicing display effect. [0003] In view of the abo...

Problems solved by technology

However, none of these traditional methods can achieve a smooth transition between the light emitted from the LCD frame area and the light emitted from the display area, and there will be a sudden change in light intensity at the seam during the implementation process (such as figure 1 shown), which will inevitably cause visual dark lines and affect the splicing display effect
