Embodiment Construction

[0037]Liquid crystal display is a flat and ultra-thin display device, which is composed of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube.

[0038] The LCD panel is an important factor that determines the brightness, contrast, color, and viewing angle of the LCD display. The quality and technology of the LCD panel are also related to the overall performance of the LCD display. Therefore, the LCD panel is the most important component of the LCD display.

[0039] Black point performance can also be called black level: it refers to how "black" the screen can be when it displays the darkest color. To give a simple example in reality: St...

Abstract

The invention discloses a display panel and a display device, and aims at solving the problems that a double-cell display panel in the prior art is expensive and thick and low in light transmittance.The display panel only includes two polaroids, a polaroid between a liquid crystal display panel and a liquid crystal light valve panel is omitted, a liquid crystal layer of the liquid crystal light valve panel is doped with a dichromatic dye, an electrode structure of the liquid crystal light valve panel forms an electric field by using the characteristic that the dichromatic dye has a strong capability of absorbing incident light in parallel with the long molecular axis but a weak capability of absorbing incident light vertical to the long molecular axis, so that liquid crystal molecules rotate in the interface in parallel with the light incident direction. Thus, the direction of incident light input to the liquid crystal display panel is not changed, the luminous flux is controlled, thenumber of polaroids in the display panel can be reduced, the cost is reduced, the thickness of the display panel is reduced, and the light transmittance is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Liquid crystal display is a flat and ultra-thin display device, which is composed of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. [0003] The LCD panel is an important factor that determines the brightness, contrast, color, and viewing angle of the LCD display. The quality and technology of the LCD panel are also related to the overall performance of the LCD display. Therefore, the LCD panel is the most important component of the LCD display. [0004] Bla...
