Abstract

The invention relates to a driving circuit and a display panel. The driving circuit comprises a driving chip, a detection signal generating circuit and a feedback circuit. The detection signal generating circuit is configured to receive a first voltage signal and a second voltage signal, and generate a detection control signal for performing aging detection according to the first voltage signal and the second voltage signal. The feedback circuit is configured to adjust the voltage outputted by the driving chip to the voltage required to perform the aging detection according to the detection control signal. In the driving circuit provided by the invention, the detection control signal configured to perform the aging detection can be generated by the detection signal generating circuit, so that the feedback circuit adjusts the voltage outputted by the driving chip to the voltage required to perform the aging detection according to the detection control signal, the voltage can be conveniently raised in the aging detection according to actual needs to meet the aging detection requirements, and the diversity requirements of the voltage required to perform the aging detection in the aging detection process are satisfied.

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...
