Abstract

The invention discloses a display panel and a display device. The display panel includes: a heating unit and a temperature detection unit; wherein the temperature detection unit is used to detect the temperature of the first heating area and the temperature of the non-heating area, and output the detection result to the heating unit; the heating unit is located in the first heating area and is used to heat the display panel according to the detection result of the temperature detection unit. Since the OLED light-emitting device in the organic light-emitting unit decreases its light-emitting brightness with the increase of temperature, the present invention controls the heating unit to conduct the heating on the first heating region according to the temperature results of the non-heating region and the first heating region detected by the temperature detection unit. The heating increases the temperature of the first heating region on the end of the display panel close to the driving chip, thereby reducing the display brightness of the organic light-emitting units in this region, thereby improving the uniformity of the display brightness of the display panel.

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] With the advancement of display technology, Organic Light Emitting Diode (OLED) is one of the hotspots in the field of flat panel display research today, and more and more Active Matrix Organic Light Emitting Diode (AMOLED) display Panels have entered the market. Compared with traditional thin film transistor liquid crystal display panels (Thin Film Transistor Liquid Crystal Display, TFT LCD), AMOLED has faster response speed, higher contrast ratio and wider viewing angle. [0003] Each pixel unit in the existing OLED display panel corresponds to a light emitting device, figure 1 It is a schematic structural diagram of an OLED light-emitting device in the prior art, such as figure 1 As shown, the structure of each light-emitting device mainly includes: cathode layer, electron injection layer, electron ...
