摘要
The present disclosure relates to a pixel circuit, a compensation method and a display device. The pixel circuit includes a first switching circuit for supplying a data voltage to a first node in response to a first scan signal being valid, a second switching circuit for conductively connecting a sensing signal line with a second node in response to a second scan signal being valid, a reset circuit for supplying a reset voltage to the sensing signal line in response to a reset control signal being valid, a light-emitting element, and a driving transistor for enabling, when the light-emitting element emits light, the sensing signal line to be charged in response to the second scan signal being valid and the reset control signal being invalid, the voltage of the sensing signal line is sensed after it was charged so as to compensate the data voltage.
說明書
According to the compensation method for the pixel circuit provided by the embodiment of the present disclosure, the voltage of the light-emitting element may be sensed during a display process (namely, when the light-emitting element is in a light-emitting state). In this way, the aging condition of the light-emitting element may be determined according to the sensed voltage of the light-emitting element, so that the aging compensation may be performed for the light-emitting element by using the sensed voltage of the light-emitting element during the display process. This avoids the brightness decay that would occur during the display process, thus improving a displaying effect of products, and improving a user experience.
