Problems solved by technology
However, in the prior art, on the one hand, the number of disconnected signal lines on both sides of the through hole is large, and every two disconnected signal lines need to be electrically connected through a winding wire, which leads to A large number of winding wires are arranged near the hole to form the frame area of the through hole. The larger the frame area is, the lower the proportion of the display area of the display panel is; Different loads lead to different attenuation degrees of signals transmitted on the two signal lines

The embodiment of the invention provides a display panel and a display device, and relates to the technical field of display, for reducing the number of winding lines in a frame area and reducing theloading difference among signal lines. The display panel comprises a through hole, the frame area and a picture display area, wherein the picture display area is provided with first fixed voltage signal lines and second fixed voltage signal lines extending along a first direction; the first fixed voltage signal lines and the second fixed voltage signal lines are positioned on two sides in the first direction of the frame area; a fixed voltage bus is arranged in the frame area in a surrounding manner, and the first fixed voltage signal lines and the second fixed voltage signal lines are electrically connected with the fixed voltage bus; and the line width B of the fixed voltage bus satisfies the following relation: B is greater than or equal to pi / 2xA and smaller than or equal to pi / 2x{ln[D / (2xP)]+C}, wherein A is the line width of the first fixed voltage signal lines and the second fixed voltage signal lines, C is the Euler's constant, D is the diameter of the circle corresponding to an arc-shaped line in the fixed voltage bus, and P is the length of a pixel circuit in the first direction. The display panel is used for realizing picture display.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] With the diversified designs of display panels, at least one through hole is provided inside some display panels. For example, for a full-screen display panel, in order to avoid the camera component occupying space in the non-display area, the camera can be arranged in the through hole of the display area, and the display panel is transparent but not cut at the through hole. At this time, the through hole It is a through hole that does not penetrate the two substrates in the display panel; or, the display panel is cut at the through hole to form a through hole that penetrates the two substrates. [0003] Since there is a through hole in the middle of the display area, the disconnected signal lines located on both sides of the through hole in the display area cannot be directly connected in the throu...
