Abstract

The embodiment of the invention provides a display panel. The display panel comprises a light guide plate, a liquid crystal cladding, conductive glass and a light source. The light guide plate comprises a first surface and a second surface which are oppositely arranged; the liquid crystal cladding is arranged on the first surface; the conductive glass is arranged on the side, away from the first face, of the liquid crystal cladding, and the refractive index of the liquid crystal cladding can be adjusted through the conductive glass. The light source is arranged on the side face of the light guide plate, wherein the refractive index of the light guide plate is greater than that of the liquid crystal cladding. According to the display panel, the conductive glass and the liquid crystal cladding are arranged, the refractive index of the liquid crystal cladding is adjusted by the conductive glass through an electric field, and regional backlight adjustment can be realized while the thickness of a machine body is maintained and the penetration rate is not reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a display panel manufacturing method, and a display device. Background technique [0002] Regional backlight adjustment technology is a new technology to enhance the display effect of Liquid Crystal Display (LCD). It divides the image signal into several regions through the TV system, analyzes and calculates according to the image brightness of each region, and then automatically controls the backlight of each region. The brightness of the source. Doing so can greatly improve the LCD dark state and enhance the contrast. Previously, the design of double-layer liquid crystal cells was also used to realize regional backlighting, but this design would seriously affect the transmittance of the panel and increase the power consumption of the backlight. Therefore, a better solution is needed to realize regional backlight adjustment. Contents of the invent...
