Embodiment Construction

[0046] 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.

[0047] As mentioned in the background technology, the existing display panel has brightness attenuation as the lighting time is prolonged. In the prior art, the chip is usually used to detect the threshold voltage change of the thin film transistor in the driving circuit to perform corresponding voltage compensation to achieve brightness. Compensation, but the data processing volume of the chip is large, and the response speed is slow, so it cannot accurately and timely compensate the brightness attenuation of the ...

Abstract

The embodiment of the invention discloses a brightness compensation method and device of a display panel and the display device. The brightness compensation method of the display panel comprises the steps of obtaining brightness values at multiple different moments; determining brightness attenuation fitting parameters according to the brightness values at the different moments and a brightness attenuation formula; resetting the initial brightness value, and determining an optimal brightness attenuation fitting curve according to the set initial brightness value and the brightness attenuationfitting parameter; and performing brightness compensation according to the optimal brightness attenuation fitting curve and the display panel lighting time. According to the technical scheme providedby the embodiment of the invention, the brightness attenuation of the display panel can be compensated accurately in real time.
