Seam elimination device and seamless splicing display equipment

Abstract

The invention provides a seam elimination device, which includes a first optical assembly arranged directly in front of the display area and a second optical assembly arranged directly in front of the frame area and corresponding to the first optical assembly; the first optical assembly, the second optical assembly The width of the components is consistent with the width of the frame area. Both the first optical component and the second optical component include a plurality of first deflectors; the light exit surfaces of each first deflector are cylinders. The present invention also provides an anti-seam device, which includes a third optical assembly arranged in front of the display area and a fourth optical assembly arranged in front of the frame area and corresponding to the third optical assembly; the third optical assembly, the fourth The widths of the optical components are consistent with the total width of the adjacent spliced ​​frame regions, and the third optical component and the fourth optical component both include a plurality of second deflectors; the light exit surfaces of each deflector are planes. By adopting the present invention, the smooth transition between the light emitted from the frame area and the light emitted from the display area can be realized, and the display effect can be 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
