Abstract

The invention relates to a driving circuit and a display panel. The driving circuit includes a driving chip, a detection signal generating circuit and a feedback circuit. The driver chip is used to output the working voltage. The detection signal generating circuit is used for receiving a trigger signal, and generating a detection control signal for aging detection according to the trigger signal. The feedback circuit is used to receive the detection control signal output by the detection signal generation circuit and the operating voltage provided by the driving chip, generate a feedback voltage according to the detection control signal and the operating voltage and output it to the driving chip, so that The driving chip adjusts the working voltage to a voltage required for aging detection according to the feedback voltage.

Description

technical field [0001] The invention relates to the display field, in particular to a driving circuit and a display panel. Background technique [0002] The Thin Film Transistor Liquid Crystal Display (TFT-LCD) panel is one of the main products of the current flat panel display, and has 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 drive 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 manufactured. The burn-in detection is mainly used to detect whether there are problems such as liquid crystal cell wire defects and slight damage to electronic components. These problems may easily lead to defects in the display panel during user use, such as disconnection and corrosion, which seriously affect the...
