Abstract

The invention discloses a shift register circuit and a display panel. The shift register circuit comprises a pull-up module, the pull-up module comprises a first pull-up unit, the first pull-up unit comprises a first pull-up subunit and a second pull-up subunit, a first input end of the first pull-up subunit is connected to a first control signal end; the first input end of the second pull-up subunit is connected to a second control signal end, the second input end of the first pull-up subunit and the second input end of the second pull-up subunit are both connected to a pulse signal end, and the first pull-up subunit is used for generating a pull-up signal when a first control signal of the first control signal end is a preset trigger signal. The second pull-up subunit is used for generating a pull-up signal when a second control signal of the second control signal end is a preset trigger signal, high and low levels of the first control signal and the second control signal are alternated, and when one control signal is a high-level signal, the other control signal is a low-level signal. According to the embodiment of the invention, the first pull-up unit can normally generate the pull-up signal.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a shift register circuit and a display panel. Background technique [0002] With the development of display technology, display panels with thinner body, lower cost and energy consumption, faster response speed, better color purity and brightness, and higher contrast ratio have been widely used in various electronic products. [0003] In the related art, the display panel includes a shift register circuit, and the shift register circuit is mainly used for scanning multi-level scan lines, so as to scan the pixel array electrically connected to the scan lines by scanning the multi-level scan lines, and then cooperate with other circuits The screen is displayed according to the structure. [0004] However, the pull-up module in the shift register circuit that generates the pull-up signal is continuously affected by the electrical stress of the DC voltage, whi...
