Abstract

The invention relates to a driving circuit and a display panel. The driving circuit comprises a driving chip, a detection control signal generation circuit and a feedback circuit, wherein the first input end of the detection control signal generation circuit is connected with the power voltage input end of the driving chip and the second input end is grounded, and thus, when the power voltage is larger than threshold voltage, the power voltage is received through the first input end, low-level voltage signals are received through the second input end, and detection control signals are generated according to the power voltage and the low-level voltage signals; and the first input end of the feedback circuit is connected with the output end of the detection control signal generation circuitand the second input end is connected with the output end of the driving chip, and thus, the detection control signals outputted by the detection control signal generation circuit and the working voltage provided by the driving chip are received, feedback voltage is generated according to the detection control signals and the working voltage and is outputted to the driving chip, and the driving chip adjusts the working voltage to the voltage needed for aging detection according to the feedback voltage.

Description

technical field [0001] The present application relates to the field of display technology, 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, wh...
