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

A pixel structure, a liquid crystal display panel, a method of operating the liquid crystal display panel, and a display device are disclosed. The pixel structure includes a light shutter for switching between first and second states, wherein in the first and second states, the light shutter only allows first polarized light having a first polarization direction and second polarized light having a second polarization direction to pass, respectively; a birefringent filter for causing emergent paths of the first and second polarized light to be first and second paths, respectively; a first liquid crystal unit and a first color filter in the first path and corresponding to a first sub-pixel region, wherein the first color filter is at a light-emergent side of the first liquid crystal unit; and a second liquid crystal unit in the second path and corresponding to a second sub-pixel region.

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...
