Abstract

The invention relates to a drive circuit and a display panel. The drive circuit comprises a drive chip, a detection signal generating circuit and a feedback circuit, wherein the drive chip is used foroutputting work voltage; the detection signal generating circuit is used for receiving a triggering signal, and generating a detection control signal used for ageing detection according to the triggering signal; the feedback circuit is used for receiving the detection control signal output by the detection signal generating circuit and work voltage provided by the drive chip, generating feedbackvoltage according to the detection control signal and the work voltage and outputting the feedback voltage to the drive chip, so that the drive chip can adjust the work voltage to the voltage needed by ageing detection according to the feedback voltage.

Description

Technical field [0001] The present invention relates to the field of display, in particular to a driving circuit and a display panel. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) panels are currently one of the main products of flat panel displays and have become an important display platform in the modern information technology industry and video products. During the working process of the TFT-LCD display panel, the driving chip on the printed circuit board mainly provides power and signals to the display area to realize image display. [0003] In the production process, aging testing is generally performed after the display panel is completed. The aging detection is mainly used to detect whether there are problems such as liquid crystal cell line defects and slight damage to electronic components. These problems can easily cause defects in the display panel during use by the user, such as disconnection, corrosion, etc., which seriously affe...
