Problems solved by technology
[0003] In the hole-digging area where the camera and other devices are placed, since it is not used as a display area (that is, the hole-digging area is a non-display area), the signal lines of the surrounding display area need to be routed around the hole-digging area, that is, the wiring around the hole-digging area The driving signal line needs to bypass the hole-digging area, resulting in a difference in load (RC Loading) between the driving signal line bypassing the hole-digging area and other driving signal lines, resulting in a split-screen display

Embodiment Construction
[0028] At present, in the full screen, the driving signal lines around the hole-digging area need to be routed around the hole-digging area, such as figure 1 As shown, the spacing between the driving signal lines around the hole-digging area becomes smaller, thereby increasing the parasitic capacitance and load of the driving signal lines. Moreover, in order to realize the narrow frame design of the hole-digging area, the driving signal lines around the hole-digging area are arranged in a multi-layered manner, which will also increase the parasitic capacitance and load of the driving signal lines. In the end, the load of the driving signal lines around the hole-digging area is greater than that of other areas, so that the problem of split-screen display occurs during gray-scale display and heavy-duty images.
[0029] Aiming at the problem of display split screens in the hole-digging area in the prior art, embodiments of the present invention provide a display panel and a displ...

The invention discloses a display panel and a display device, by setting an overlapping area between at least one first fan-out trace and one second fan-out trace smaller than an overlapping area between any one third fan-out trace and one fourth fan-out trace, reducing the parasitic capacitance of the first outgoing trace and the second outgoing trace electrically connected to the drive signal line located in the first display area, so that that load is reduced, so as to compensate the load portion of the driving signal line in the first display area higher than that of the driving signal line in the second display area, thereby improving the difference in the load amount between the driving signal line in the first display area and the driving signal line in the second display area as awhole, and alleviating the problem of display splitting when the gray scale display and the picture are reloaded.
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] At present, display panels with a full-screen design are becoming more and more popular among consumers. The full-screen is designed with ultra-narrow borders around it, combined with a panel structure designed by digging holes in the display area to place cameras and other devices. The full-screen is a panel display The highest proportion panel frame. [0003] In the hole-digging area where the camera and other devices are placed, since it is not used as a display area (that is, the hole-digging area is a non-display area), the signal lines of the surrounding display area need to be routed around the hole-digging area, that is, the wiring around the hole-digging area The driving signal line needs to bypass the hole-digging area, resulting in a difference in load (RC Loading) between the driving signal line byp...
