In recent years, in order to obtain better use experience, a full screen becomes a development trend of display devices such as smart phones, and various manufacturers have focused on developing feasible technologies. However, a full screen with 100% coverage may conflict with components such as a handset of the electronic device, and at present, a more general method is to provide a device avoiding groove (i.e., notch region) in the middle of the upper side of the display screen, and in order to enable pixel units on display screen partitions on the left and right sides of the notch region to obtain as uniform driving as possible, middle routing lines are adopted to connect grid lines of pixel units on corresponding lines on the left and right sides, so as to perform bilateral driving on the pixel units of the display screen partitions on the left and right sides of the notch region.
However, the middle of the pixel units of the display screen partitions on the left and right sides of the notch area is too much routed, so that the edge (i.e., the border area) of the notch area has a wider non-display area, and the screen occupation ratio is reduced. In particular, in order to make the loads on the intermediate traces and the corresponding gate lines uniform, RC compensation needs to be performed on the intermediate traces by providing a parallel plate capacitor or the like, which widens the non-display area in the border region and further reduces the screen occupation ratio.
