Embodiment Construction

[0033] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0034] See figure 2 , The grayscale control structure 100 of the present invention includes a first substrate 10, a light extraction layer 20, an electrode layer 30, a liquid crystal layer 40, a filter layer 50, and a second substrate 60 stacked in sequence. The pretilt angles of the first substrate 10 and the second substrate 60 are both 2°, so as to shorten the response time of the liquid crystal under voltage driving. An insulating layer is provided between the electrode layer 30 and the liquid cryst...

Abstract

The invention provides a gray scale control structure which comprises a first substrate, a light extraction layer, an electrode layer, a liquid crystal layer, a filter layer and a second substrate which are sequentially arranged in a laminating mode. A plurality of side-by-side strip electrodes are arranged in the electrode layer, so that a lens unit can be formed in the liquid crystal layer; the filter layer comprises a light emergence strip and a black matrix which are arranged side by side; the light emergence strip is opposite to the lens unit; a light extraction grating is arranged in the light extraction layer; the light extraction grating is opposite to the light emergence strip; the projection of the light emergence strip on the light extraction layer covers the light extraction grating. The gray scale controls the size of a gray scale by regulating and controlling a deflection direction of incident light, meanwhile, can improve light transmittance, and has a high contrast ratio.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a gray-scale control structure and a corresponding gray-scale control method, and also provides a liquid crystal display panel and a display device. Background technique [0002] Compared with traditional CRT displays, liquid crystal displays have the advantages of zero radiation, low energy consumption, and low heat dissipation. In terms of image display function, the liquid crystal display can accurately restore the image without any geometric or linear distortion. At the same time, the liquid crystal display also has the characteristics of sharp characters, and the display is stable without flickering. It is precisely because of these advantages that liquid crystal displays have been widely used. [0003] Such as figure 1 The display panel of the existing liquid crystal display includes a color film layer and two polarizing layers. This structural feature makes the light tr...
