Problems solved by technology

The light output side of the existing liquid crystal display panel is provided with a polarizer, which only allows the polarized light of a specific polarization direction to pass through, so that the transmittance of the liquid crystal display panel is low. The existing method to increase the transmittance of the liquid crystal display panel is to increase the Aperture ratio or increase the brightness of the backlight, both of which will sacrifice contrast and increase power consumption

Abstract

The invention provides a liquid crystal display panel, a display device and a working method, and belongs to the technical field of display. Each pixel region of the liquid crystal display panel comprises a first sub-pixel region and a second sub-pixel region; and each pixel region comprises a light valve, a double refraction structure, first liquid crystal unit, a first filtering unit, a second liquid crystal unit and a second filtering unit, wherein the light valve can be switched between a first state and a second state; in the first state, the light valve only allows incident first polarized light in a first polarization direction to pass through; in the second state, the light valve only allows incident second polarized light in a second polarization direction to pass through; the double refraction structure does not change an emergent path of the vertically incident first polarized light and can enable an emergent path of the vertically incident second polarized light to be shifted; the first liquid crystal unit directly faces a light outlet of the light valve; and the second liquid crystal unit is positioned on the emergent path of the second polarized light. According to the invention, transmittance and contrast of the display device can be improved in a case of not increasing power consumption.

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. Background technique [0002] The light transmittance of the screen is an important parameter that affects the brightness, contrast and other characteristics of the screen. High transmittance will make the display color brighter and more realistic. The light output side of the existing liquid crystal display panel is provided with a polarizer, which only allows the polarized light of a specific polarization direction to pass through, so that the transmittance of the liquid crystal display panel is low. The existing method to increase the transmittance of the liquid crystal display panel is to increase the Aperture ratio or increasing the brightness of the backlight, both of which sacrifice contrast and increase power consumption. Contents of the invention [0003] The technical problem to be solved by the...
