Problems solved by technology

[0002] The existing liquid crystal display includes a liquid crystal display panel, a backlight source, and polarizers attached to the light-emitting side and the light-incoming side of the liquid crystal display panel. The liquid crystal display panel includes a color filter substrate, an array substrate, and an For the liquid crystal layer, since the transmittance of the color filter substrate, array substrate, and polarizer cannot reach 100%, the light energy emitted by the backlight will be greatly lost, and finally the light transmittance of the liquid crystal display can only reach about 5%, resulting in liquid crystal Low light transmittance of the display, high energy consumption, low energy utilization, etc.

Abstract

The invention provides a liquid crystal display panel, a display device and a working method thereof, belonging to the field of display technology. The liquid crystal display panel includes a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. Each pixel area of ​​the liquid crystal display panel includes: a black matrix located on the second substrate, and the black matrix defines a The opening area; the light-trapping layer on the first substrate, the orthographic projection of the light-trapping layer on the second substrate falls into the black matrix; the light-reflecting layer between the liquid crystal layer and the black matrix; the first substrate and the second substrate Between the first electrode unit and the second electrode unit; after voltage is applied to the first electrode unit and the second electrode unit, the liquid crystal molecules in the corresponding regions of the liquid crystal layer can be deflected to form a microprism structure. The invention can improve the light extraction efficiency of the liquid crystal display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel, a display device and a working method thereof. Background technique [0002] The existing liquid crystal display includes a liquid crystal display panel, a backlight source, and polarizers attached to the light-emitting side and the light-incoming side of the liquid crystal display panel. The liquid crystal display panel includes a color filter substrate, an array substrate, and an For the liquid crystal layer, since the transmittance of the color filter substrate, array substrate, and polarizer cannot reach 100%, the light energy emitted by the backlight will be greatly lost, and finally the light transmittance of the liquid crystal display can only reach about 5%, resulting in liquid crystal The light transmittance of the display is low, the energy consumption is high, and the energy utilization rate is low. Contents of the invention [0003]...
