Abstract

The invention relates to the technical field of display. The invention provides a gate drive circuit and a display panel. The gate drive circuit comprises a plurality of cascaded shift register units.Each shift register unit comprises a first output end and a second output end. The shift register unit also comprises a shift register circuit, used for inputting a first shift signal to the first output end; and a logic gate, the first input end of the logic gate being connected with the first output end of the shift register unit of the stage, the second input end being connected with the firstoutput end of the shift register unit of the previous stage, and the output end being connected with the second output end and used for outputting a second shift signal to the second output end. A first shift signal output by the gate drive circuit can be used for a gate drive signal and a reset signal of the pixel drive circuit. The second shift signal can be used as an enable signal of the pixel driving circuit, so that the enable driving circuit does not need to be arranged to the pixel driving circuit, and the width of the frame of the display panel can be reduced by reducing the number of the gate drivers.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a gate drive circuit and a display panel. Background technique [0002] The pixel driving circuit usually adopts an internal compensation setting method to avoid abnormal display caused by the electrical difference of the driving transistor. A pixel driving circuit in an internal compensation mode requires multiple driving signals (eg, Reset, Gate, EM signals) to cooperate with each other. [0003] In the related art, it is usually necessary to set up multiple driving circuits for outputting the above-mentioned driving signals, for example, the gate driving circuit GOA outputs the Gate signal, and the enabling driving circuit EOA outputs the enabling signal. [0004] However, the above-mentioned driving circuit is generally arranged in the edge routing area of ​​the display panel, and the structure of the above-mentioned driving circuit is relatively complicated, which will inc...
