Embodiment 1

[0028] Embodiment 1 of the present application provides a direct type liquid crystal module, its local structure is as follows Figure 1A shown. A direct-type liquid crystal module 100, including a back plate 110 and a folded edge 111 arranged on the edge of the back plate 110, the back plate 110 and the folded edge 111 form an accommodation cavity 120, and optical The diaphragm group 160, the grid optical component 150 carrying the optical diaphragm group 160, and the light emitting units 140 arranged in an array;

[0029] A sunken groove 151 is formed on the grid optical component 150 corresponding to the position of the light-emitting unit 140, and an opening for accommodating the light-emitting unit 140 is formed on one side of the bottom of the sunken groove 151. On the other side surface, the inner wall of the sinker 151 is a reflective surface. The light-emitting unit 140 is placed in the opening at the bottom of the sinker 151 , and can also play a role in positioning...

Abstract

The invention provides a liquid crystal module and a liquid crystal display device. The liquid crystal module is a direct type liquid crystal module and includes an optical film set and a grid-like optical component. The portion, corresponding to a light emitting unit, of the grid-like optical component is provided with a settling tank, the bottom of the settling tank is provided with an opening in which the light emitting unit can be accommodated, the inner wall of the settling tank is a reflection surface, and the disclosed liquid crystal display device includes a panel and the liquid crystal module. The problems that the light diffusion angle in an ultra-multi-subregion liquid crystal module is large, light overlapping is formed in adjacent subregions, and thus light convergence is notstrong is solved, and meanwhile the liquid crystal module is thinned.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal module and a liquid crystal display device. Background technique [0002] With the development of LCD module technology, multi-zone Local Dimming (LD), HDR, and thinning, the liquid crystal display device has higher dynamic contrast, better image quality, and more fashionable appearance. It is also more and more popular among consumers. sought after. When LD technology is introduced into the TV, the backlight of the TV is usually partitioned, with several lights in one area or one light in one area. The main board adjusts the brightness of each area in real time according to the brightness algorithm of the image signal, so as to achieve the backlight. The purpose of real-time brightness adjustment is to improve dynamic contrast and realize energy saving. Due to the limitation of the backlight scheme, on the one hand, the current side light module cannot realiz...
