Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] The common panel structure from top to bottom is: upper polarizer 1 , upper glass substrate 2 , liquid crystal molecules 3 , lower glass substrate 2 , and lower polarizer 6 . Due to the divergence of light, the backlight LED light is still divergent light after passing through the O / C, so a small part of the light can also pass through the black field, resulting in a black field that is not black enough and the contrast is low. Example: if Figure 1 The two pixels in the red circle, assuming the left pixel is ON and the right pixel is OFF, and the right liquid crystal is not closed tightly, the light directly below the pixel and obliquely ...

Abstract

The invention discloses a high-contrast LCD (liquid crystal display) screen. The novel design panel structure comprises, from top to bottom in sequence, an upper polaroid, an upper glass substrate, liquid crystal molecules, a transparent filling material, a special structure lower glass substrate and a lower polaroid. The liquid crystal molecules are closely-arranged molecules, and there is a gapbetween the molecules for light input. Shading areas are uniformly distributed on the upper surface of transparent filling material. Concave spaces with equal spacing are dug in the glass substrate and under the special structure, and the concave spaces are filled with the transparent filling material. The high-contrast LCD screen has the advantages that the brightness of the vertical front view is improved; a black field can intercept more oblique light, so that the black field is darker and a white field is brighter; and the contrast is improved to make watching more shocking.

Description

technical field [0001] The invention relates to a liquid crystal screen, in particular to a high-contrast liquid crystal screen. Background technique [0002] At present, the use of ordinary panels has the problems of low picture contrast and poor viewing fidelity. The existing high-contrast TVs on the market all use the Local Dimming technology to dynamically adjust the backlight, thereby improving the contrast. However, due to the increase in backlight materials and driving costs, the cost of the whole machine has risen sharply. This patent is to improve the contrast by adjusting the panel. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a high-contrast liquid crystal screen to solve the problem of low contrast. [0004] The common panel structure from top to bottom is: upper polarizer, upper glass substrate, liquid crystal molecules, lower glass substrate, and lower polarizer. Due to the divergence of...
