Abstract

The invention provides an OLED display panel and a display device, and the OLED display panel comprises a display area and a non-display area surrounding the display area, and also comprises a plurality of light-emitting devices arranged in the display region in an array manner; a pixel driving circuit used for driving the light-emitting devices to emit light; a light sensor arranged in the non-display area and is used for converting a light intensity signal of ambient light into a first electric signal; and a feedback circuit used for determining a compensation signal according to a difference value between the first electric signal and a preset electric signal; wherein the display area comprises a first display area close to the light sensor, and the pixel driving circuit corresponding to the light-emitting devices in the first display area is further used for inputting a compensation signal to the corresponding light-emitting devices so as to adjust the light-emitting brightness ofthe light-emitting devices. According to the invention, the brightness of the light-emitting devices close to the light sensor is compensated, so that the actual display brightness of the first display area is changed along with the difference of the ambient light intensity, and the brightness of a watched picture can be uniform.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel and a display device. Background technique [0002] Existing large-size OLED display panels usually use multiple small-size display panels to splice to achieve super-large-screen display, but with the maturity of technology, non-splicing super-size screens are gradually becoming possible, but the space span of super-large-size OLED display panels Large, the brightness of the ambient light in each area of ​​the panel is different, which will cause the viewer to have uneven brightness of the picture on the light sensor, thus affecting the viewing effect. [0003] Therefore, the existing OLED display panel has the technical problem of uneven brightness of viewing pictures, which needs to be improved. Contents of the invention [0004] Embodiments of the present application provide an OLED display panel and a display device, which are used to allev...
