Abstract

The invention provides a display panel, a brightness adjusting method thereof and a display device. The display panel comprises a back plate and a color film cover plate covering the back plate, wherein a pixel unit is arranged on the back plate, and the color film cover plate is provided with a color film corresponding to the pixel unit. The color film cover plate is further provided with: a photoelectric sensing unit, wherein the photoelectric sensing unit is used for converting ambient light acting on the pixel unit into an electric signal, and the positive projection of the photoelectric sensing unit and the positive projection of the pixel unit on the back plate do not coincide; and a signal conversion unit, wherein the signal conversion unit is used for converting the electric signalinto a sensing signal so as to adjust the display brightness of the pixel unit. The problem of automatic brightness adjustment of the display device is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a method for adjusting brightness thereof, a manufacturing method, and a display device. Background technique [0002] Currently, display devices are appearing in the display market and the daily life of the general public in increasingly diverse and novel forms, and these display devices include technologies that are quite mature. Among them, the organic light emitting diode (Organic Light Emitting Diode, OLED) display is more and more used in the field of high-performance display due to its advantages such as higher aperture ratio. [0003] For a display device, the display brightness has an important impact on the display effect. Improper display brightness will not only damage the user's eyes, but also bring a bad user experience to the user. Contents of the invention [0004] In view of this, the object of the present invention is to provide a di...
