Abstract

The invention discloses a display panel and a display device, wherein the display panel comprises a plurality of scanning lines, a multi-level shifting register, a plurality of compensation units, wherein the plurality of scanning lines are arranged along a first direction and extend along a second direction, and are positioned in a display area; a starting signal input end of a (M+2)th-level shifting register is connected with a first output end of a Mth-level shifting register, a second output end of each-level shifting register is connected with one corresponding scanning line; the plurality of compensation units are positioned on a peripheral circuit area; a control end of each compensation unit is used for inputting a clock signal, and an output end is connected with a corresponding scanning line which is connected with one shifting register; an input end is connected with a corresponding first output end of a first N-level shifting register of the shifting register, and is used for compensating signals on the scanning lines according to the control end and input end thereof, wherein M and N are positive integer. According to the technical scheme provided by the embodiment ofthe invention, the scanning signal on the scanning lines can be compensated, display uniformity can be improved, the border of the display panel is small.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] In the display process of the existing display panel, the shift register located in the non-display area generally outputs the scan signal to the scan line, and the scan signal on the scan line drives the pixels in the connected display area to charge and display. [0003] In the interlace driving method of double-sided driving, the scan signal output by the shift register circuit attenuates at the end of the scan line, especially in the case of a large panel with heavy resistance and capacitance load RC loading, the scan signal The attenuation is more serious, which will cause insufficient opening of the transistors in the pixels connected to the end of the scanning line, low pixel charging efficiency, resulting in inconsistent brightness between the edge and the middle area of ​​the ...
