Abstract

The invention discloses a display panel and a display device, and belongs to the technical field of display. The display panel comprises a display area, wherein the display area includes a plurality of data lines and a plurality of pixel electrode; first sub-pixels and second sub-pixels in the display area are alternately arranged to form pixel rows, one pixel row is driven by a first scanning line and a second scanning line together, and the time when a scanning signal is inputted into the first scanning line and the time when a scanning signal is inputted into the second scanning line are overlapped when the first scanning line and the second scanning line drive the same pixel row; each sub-pixel includes a pixel electrode; each first sub-pixel includes a first transistor, and each second sub-pixel includes a second transistor; the parasitic capacitance between a source electrode and a grid electrode in the first transistor is the first parasitic capacitance, the parasitic capacitance between a source electrode and a grid electrode in the second transistor is the second parasitic capacitance, and the second parasitic capacitance is greater than the first parasitic capacitance. The display panel can ensure that the brightness of the second sub-pixels and the brightness of the first sub-pixels tend to be the same and improve the display uniformity.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] In the existing display panel technology, there is a design of dual scanning lines, that is, a design in which two scanning lines are used to drive the same row of sub-pixels. The design of double scanning lines can reduce the load of data lines, for example, the number of data lines can be reduced, or the frequency of data switching of data lines can be reduced. Therefore, the design of double scanning lines can reduce the load of the driving circuit and reduce the function of the display panel. consumption. However, the existing dual-scanning-line structure may cause vertical stripes during display, which affects the viewing effect. Contents of the invention [0003] In view of this, the present invention provides a display panel and a display device, which solve the technical problems of ...
