Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0035] As mentioned in the background art, the display brightness of different display areas in the display panel is different, resulting in uneven display brightness of the display panel, which affects the display effect of the display panel. After research by the inventor, it is found that the reason for the above problems is that the display device includes a display panel and a driver chip, and the display panel includes a signal line connected to the driver chip. The pixel circuit provides power. The power l...

Abstract

The embodiment of the invention discloses a display panel, a brightness compensation method thereof and a display device. The display panel comprises a signal input end, wherein the area, close to the signal input end, in the display panel is the near end, and the area, away from the signal input end, in the display panel is the far end; and a pixel including a thin film transistor, wherein the size of the thin film transistor located at the far end is larger than that of the thin film transistor located at the near end. According to the technical scheme of the embodiment of the invention, the size of the thin film transistor at the far end is set to be larger than that of the thin film transistor at the near end, so that the voltage drop generated by the display signal on the pixel circuit at the far end is smaller than the voltage drop generated by the display signal on the pixel circuit at the near end, and the display brightness uniformity of the far end and the near end of the display area is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a brightness compensation method thereof, and a display device. Background technique [0002] With the continuous development of display technology, the display effect requirements of the display panel are also getting higher and higher. At present, the display brightness of different display areas in the display panel is different, resulting in uneven display brightness of the display panel, which affects the display effect of the display panel. Contents of the invention [0003] Embodiments of the present invention provide a display panel, a brightness compensation method thereof, and a display device, so as to improve the display brightness uniformity of the display panel. [0004] In a first aspect, an embodiment of the present invention provides a display panel, and the display panel includes: [0005] The signal input termina...
