Inwards concave spherical surface liquid crystal display module

Abstract

The invention discloses an inwards concave spherical surface liquid crystal display module. The inwards concave spherical surface liquid crystal display module comprises a backlight module, a liquid crystal panel arranged on the backlight module and a frame arranged on the periphery of the backlight module and the liquid crystal panel, wherein the backlight module, the liquid crystal panel and the frame are all of curved surface structures in the horizontal and vertical directions, the radius of curvature of the curved surface structure in the horizontal direction is smaller than 3000 mm, and the radius of curvature of the curved surface structure in the vertical direction is smaller than 10000 mm. The inwards concave spherical surface liquid crystal display module can effectively resolve the problems of equal-visual-range visual errors, and Mura and light leakage of picture displaying.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a concave spherical liquid crystal display module. Background technique [0002] In recent years, flat panel display technology, including liquid crystal display technology, has made great progress and has gradually replaced cathode ray tube (CRT) display technology. For a liquid crystal display, it includes a liquid crystal panel (cell), a backlight unit (BLU) and a frame. The backlight module is used to provide a light source for the liquid crystal panel, and the frame is used to fix the liquid crystal panel and the backlight module. [0003] At present, the liquid crystal display commonly used is a planar structure, which has the problem of unequal viewing distance between the human eye and the display panel, causing differences in visual effects. [0004] In order to solve the above problems, a liquid crystal display structure with a curved surface in the horizontal directi...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used liquid crystal display is a planar structure, which has the problem of unequal viewing distance between the human eye and the display panel, causing differences in visual effects

[0004] In order to solve the above problems, a liquid crystal display structure with a curved surface in the horizontal direction (such as figure 1 As shown), under the same liquid crystal driving voltage, the light transmittance of the local display area of ​​the structure changes, that is, the liquid crystal gap (cell gap) appears to be different, resulting in Mura and light leakage problems on the screen (such as figure 2 shown)
