Abstract

The invention discloses a potential conversion circuit, which comprises a first potential input terminal, a second potential input terminal, a first thin film transistor, a second thin film transistor and a delay control chip, and the delay control chip is used to control the conversion potential output The terminal outputs the first potential before delaying the output of the second potential. The invention also provides a display panel. The potential conversion circuit of the present invention and the setting of multiple potential inputs and delay control chips in the display panel overdrive the converted potential voltage during potential conversion to ensure that the accurate converted potential voltage is achieved in the shortest time; The speed and accuracy of potential conversion are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a potential conversion circuit and a display panel. Background technique [0002] With the development of science and technology, people have higher and higher requirements on the functions of the display device, and the stability of the high-low level conversion of the pixel units of the display panel has a great influence on the display quality of the display panel. [0003] When the scanning signal of the pixel unit is converted from a high-level state to a low-level state, or from a low-level state to a high-level state, due to the presence of impedance devices in the corresponding display panel, the converted low-level voltage or The converted high-level voltage may have conversion delay and conversion voltage deviation, which will affect the image display quality of the corresponding display panel. [0004] Therefore, it is necessary to provide a potential conversion circ...
