Problems solved by technology

In this case, the pixels of the special-shaped part of the display area can no longer be arranged in a rectangular array, so the number of pixels in each row is not necessarily the same, so the load (RC) of the scanning lines driving different rows of pixels is no longer the same, which leads to When the scanning lines in the special-shaped area and the non-special-shaped area provide the same scanning signal, the display brightness of the special-shaped area and the non-special-shaped area are also inconsistent. Therefore, the display uniformity of the special-shaped display panel is poor, and the display effect is not ideal.

Abstract

The invention discloses a display panel and a display device. The display panel comprises a display area and a non-display area adjacent to the display area, the display area comprises a first displayarea and a second display area, and the pixel quantities of all pixel lines of the first display area are all smaller than those of any pixel line of the second display area; scanning signal lines and fixed potential lines of the display area are in different layers, and an laminated area is in the direction perpendicular to the display panel, wherein the area of any laminated area in the first display area is larger than that of any laminated area in the second display area. By increasing the areas of the laminated areas among all scanning signal lines and the fixed potential signal lines inthe first display area less in pixel quantity, the load capacitance of all the scanning signal lines in the first display area is increased, therefore the load difference among all the scanning signal lines in the first display area and scanning signal lines in the second display areas is compensated, accordingly the display homogeneity of the display panel is improved, and the display effect isimproved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Display panels commonly used at the present stage can generally be divided into a display area for image display and a non-display area for setting peripheral driving circuits and the like. The pixels distributed in an array in the display area are respectively connected to the driving circuit in the non-display area through a switch element. Usually, each switching element is connected to a scanning line and a data line, the switching element is turned on by receiving the scanning signal of the scanning line, and the pixel is driven to display a certain gray scale by receiving the data signal of the data line. The switching elements are connected to scan lines and data lines in different combinations, so that each pixel can emit light independently. Currently, the display areas of common display panels are al...
