Abstract

The invention provides a display panel which comprises a backlight module, a liquid crystal panel and a display screen driving chip, the backlight module comprises a plurality of backlight subareas, each backlight subarea is provided with at least one backlight source, the liquid crystal panel comprises a plurality of display subareas, and each display subarea is located over the projection of thecorresponding backlight subarea. The display panel comprises a plurality of display subareas, each display subarea is provided with at least one photoelectric sensor, the photoelectric sensors are used for converting optical signals emitted by a backlight source into electric signals, and the display screen driving chip is located on the liquid crystal panel, electrically connected with the photoelectric sensors and used for adjusting the display brightness of the display subareas to be the same according to the electric signals. According to the display panel, the photoelectric sensor is arranged on the liquid crystal panel to receive the light signal emitted by the backlight source and convert the light signal into the electric signal, and the display brightness of the display subarea of the liquid crystal panel is adjusted according to the electric signal, so that the imaging quality of the display panel is improved.

Description

Technical field[0001]The present invention relates to the field of communication technologies, and more particularly to a display panel and a backlight adjustment method thereof.Background technique[0002]LCD (Liquid Crystal Display) LCD panel is a non-luminescent display device, the liquid crystal display panel display graphic or character is the result of its light modulation, the liquid crystal display panel needs to reach the function of the display by means of a backlight, and the backlight performance is good and bad It will directly affect the quality of the liquid crystal display panel.[0003]Partition backlight technology refers to a backlight of a separately controllable backlight block as a backlight of the liquid crystal display panel, which is controlled by the partition separately, so that the display brightness, contrast, and energy consumption of the liquid crystal display screen based on this technique. A substantial increase in the traditional LCD display.[0004]Howev...
