Abstract: The present disclosure relates to a liquid crystal display including a liquid crystal panel. The liquid crystal panel includes a plurality of photodetectors, a plurality of first sub-pixels and a plurality of second sub-pixels respectively corresponding to the photodetectors. Each of the photodetectors partially overlaps with an opening area of the corresponding first sub-pixel. The liquid crystal display further includes a backlight module facing toward the liquid crystal panel having a first light emission section and a second light emission section. The first light emission section faces toward the first sub-pixels, and the second light emission section faces toward the second sub-pixels. A light emission brightness of the first light emission section is greater than the light emission brightness of the second light emission section.

Abstract: A high dynamic contrast image display method and device based on a partitioned backlight is disclosed. The method includes steps of: S1: obtaining a brightness information of an arbitrary pixel of an image, S2: obtaining a low-frequency illumination signal of the arbitrary pixel by gaussian filtering, S3: according to a space division of a partitioned backlight, diving the low-frequency illumination signals as same M*N partitions, S4: for anyone of the M*N partitions, calculating a maximum value of the low-frequency illumination signals of a current partition, and S5: performing a linear compression to the low-frequency illumination signal in the current partition. In the invention, the low-frequency illumination signals are subjected to a linear compression according to the luminance range that covered by the actual backlight. Contrast spatial adaptation can be performed within the backlight brightness range, while spatial details corresponding to high-frequency reflected signals are reserved.

Abstract: Disclosed is a liquid crystal panel, comprising a plurality of pixels and a plurality of photodetectors, wherein each pixel comprises a white sub pixel, and an opening area of one white sub pixel partially overlaps with at least one photodetector, which corresponds to the white sub pixel for at least a portion of the white sub pixels, individually. Further disclosed is a liquid crystal display including the liquid crystal panel. The high penetration rate of the white sub pixels is utilized to compensate for the brightness loss caused by the occlusion of the photodetectors, so that the liquid crystal panel can achieve the purpose of even display while having the photodetectors.

Abstract: The present invention teaches a direct-lit backlight module and a related manufacturing method. The direct-lit backlight module includes a driver substrate, a reflection layer on the driver substrate, multiple mini-LEDs arranged in an array on the reflection layer, multiple reflection bumps on the reflection layer among the mini-LEDs, and an optical film set on the reflection layer, the mini-LEDs, and the reflection bumps. The mini-LEDs are electrically connected to the driver substrate. The reflection bumps jointly form a mesh dot structure. When light passes through the mesh dot structure, the light is scattered by the mesh dot structure to various directions, thereby enhancing the lighting efficiency of the direct-lit backlight module.
