Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0040] In the prior art, since there is a hole-digging area for placing sensor devices in the display area, the grid lines and data lines adjacent to the hole-digging area in the display substrate are deformed, such as figure 2 shown. Among them, such as image 3 As shown, the distance d1 between the deformed traces 301 is much smaller than the distance d2 between the normal traces 302 . The distance between the normal traces 302 is relatively large...

The invention provides a display substrate, a manufacturing method of the display substrate, a display device and a driving method of the display device, wherein the display substrate comprises a display area and a hole digging area which is located in the display area and is used for placing a sensor device; the display area comprises a first area surrounding the hole digging area and a second area except the first area, and the density of first wires in the first area is greater than that of second wires in the second area. The display substrate further comprises a transparent conductive pattern arranged in the first area, the transparent conductive pattern is located on the side, away from the substrate body of the display substrate, of the first wires, and the transparent conductive pattern is used for receiving the preset signals, and is coupled with the first wires so as to reduce the coupling capacitance between the first wires. According to the display substrate, the manufacturing method thereof, the display device and the driving method of the display device, the display effect of the display device can be improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a manufacturing method thereof, a display device and a driving method thereof. Background technique [0002] At present, display devices with sensor devices such as front cameras generally adopt the design of special-shaped full screens (such as notch screens). display devices such as figure 1 as shown ( figure 1 Middle A is the display area, B is the hole-digging area), this method can make the screen ratio higher and is favored by consumers. [0003] In the prior art, due to the placement of sensor devices in the display screen, part of the display area will be sacrificed, resulting in deformation of the grid lines and data lines in the display substrate, reducing the uniformity of pixel charging, resulting in poor display effect of the display device. good. Contents of the invention [0004] Embodiments of the present invention provide a ...
