Abstract

The invention discloses a display device. The display device comprises a double-layer liquid crystal display device with a liquid crystal optical control panel and a liquid crystal display panel, dueto the fact that the in-light surfaces and the out-light surfaces of the liquid crystal optical control panel and the liquid crystal display panel are provided with polaroids correspondingly, light emitted out from a light source needs to sequentially pass through the polaroids on the in-light surfaces and the out-light surfaces of the liquid crystal optical control panel and the liquid crystal display panel, in a dark state, due to the fact that the light of the light source is blocked for multiple times by the polaroids on the in-light surfaces and the out-light surfaces of the liquid crystal optical control panel and the liquid crystal display panel, light emitted out from the inside of the display device in the dark state can be greatly reduced, thus the brightness of the whole displaydevice in the dark state is reduced, and the contrast is improved; in addition, a light conducting panel serves as a substrate of the liquid crystal optical control panel, thus the technology of independently manufacturing the substrate can be reduced, the thickness of the display device is decreased, and the cost of the display device is lowered; and through arrangement of an optical film layer,the problem of moire patterns between the liquid crystal optical control panel and the liquid crystal display panel can be solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Liquid Crystal Display (LCD) has attracted the attention of the industry due to its small size, low power consumption, and no radiation. It has been widely used in mobile phones, vehicles, monitors, televisions, and public displays. LCD mainly includes light source (light bar), light guide plate, optical film, Cell (TFT substrate, color filter substrate and liquid crystal layer in the middle) and polarizer. The display is mainly realized by controlling the rotation of liquid crystal molecules through electrical signals. At present, various types of liquid crystal displays have been developed, and their driving modes and display effects are not the same, and each has its own strengths. Among various types, the ADS type liquid crystal display has common electrodes and pixel electrodes arranged on the array substrate, and is...
