Abstract
A driver circuit and a display panel. The driver circuit comprises a driver chip (), a detection signal generation circuit (), and a feedback circuit (). The detection signal generation circuit () is used for generating a detection control signal for performing aging detection according to the received first voltage signal and second voltage signal. The feedback circuit () is used for generating a feedback voltage and outputting same to the driver chip () according to the detection control signal and an working voltage, so that the driver chip () adjusts the outputted working voltage to a voltage required for performing the aging detection according to the feedback voltage, so as to satisfy the requirement for the diversity of voltage required for the voltage for the aging detection in the process of aging detection.
