Abstract
A drive circuit for adjusting a voltage required for aging detection using a feedback circuit comprises a drive chip (), a detection signal generation circuit (), and a feedback circuit (). The drive chip () is configured to output a working voltage. The detection signal generation circuit () is configured to generate a detection control signal for aging detection according to a received trigger signal. The feedback circuit () is configured to receive the detection control signal output by the detection signal generation circuit () and the working voltage provided by the drive chip () and to generate a feedback voltage according to the detection control signal and the working voltage and output the feedback voltage to the drive chip (), such that the drive chip () adjusts, according to the feedback voltage, the working voltage to a voltage required for aging detection. A display panel is also provided.
