Abstract: A display panel includes: a substrate, sub-pixels and a gate drive circuit. The sub-pixel includes a pixel drive circuit. The gate drive circuit includes cascaded shift registers, and a shift register is electrically connected to pixel drive circuits in a row of sub-pixels. The gate drive circuit further includes cascade input signal lines and cascade display reset signal lines. The cascade input signal line is configured to connect a shift signal terminal and an input signal terminal of two different shift register, and the cascade display reset signal line is configured to connect a shift signal terminal and a display reset signal terminal of two different shift register. The display panel has sub-pixel regions for arranging the sub-pixels and first gap regions each located between two adjacent columns of sub pixel regions: the cascade display reset signal lines and the cascade input signal lines are disposed in different first gap regions.

Abstract: The present disclosure relates to a thin film transistor. The thin film transistor may include a substrate, a source electrode on the substrate, a drain electrode on the substrate, a gate on the substrate, and an active layer on the substrate. The source electrode may include a first teeth portion. The drain electrode may include a second teeth portion. The gate may include a third teeth portion. The active layer may include a plurality of channel regions. The first teeth portion, the second teeth portion, the third teeth portion, and the active layer form a plurality of sub-thin film transistors connected in parallel. The center sub-thin film transistor has a channel region having a smallest width-to-length ratio among the plurality of sub-thin film transistors.
