Problems solved by technology

[0004] The application of optical fingerprint recognition in liquid crystal display technology has become the key direction of research breakthroughs. One of the important difficulties is that the in-plane recognition area of ​​the liquid crystal display needs to be equipped with photodetectors, which will inevitably affect the in-plane recognition area. Transmittance and gray-scale brightness, resulting in uneven display of the entire LCD display

Abstract

The invention discloses a liquid crystal displayer. The liquid crystal displayer comprises a liquid crystal panel and a backlight module. The liquid crystal panel comprises multiple photoelectric detectors, and multiple first sub-pixels and multiple second sub-pixels corresponding to the photoelectric detectors. Each photoelectric detector is partially overlapped with the open region of at least one first sub-pixel corresponding to the photoelectric detector. The backlight module is opposite to the liquid crystal panel, and comprises a first light-emitting part and a second light-emitting part, the first light-emitting part is opposite to the first sub-pixels, the second light-emitting part is opposite to the second sub-pixels, and the light-emitting brightness of the first light-emittingpart is larger than that of the second light-emitting part. The losses of the penetration rates of the first sub-pixels are compensated for by improving the light-emitting brightness of the first light-emitting part, opposite to the first sub-pixels of the liquid crystal panel, of the backlight module, and therefore the display brightness of the liquid crystal panel is uniform.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a liquid crystal display. Background technique [0002] In modern society, the interaction between people and monitors has become an important way for people to obtain and share information. Among them, LCD monitors have become the mainstream of monitors due to their good picture reproducibility. Bias, contrast, viewing angle, crosstalk, flicker and other specifications have gradually met the visual needs of the human eye for display quality. [0003] The latest breakthrough direction of mobile terminal display technology in recent years is to pay more attention to the integration of new interactive technology and the improvement of visual aesthetics. One of the important directions is the full-screen display technology with high screen ratio. The key breakthrough lies in the display panel. Compression of the upper, lower, left, and right borders, spec...
