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

The present invention provides a display substrate, a manufacturing method thereof, a display device and a driving method thereof, wherein the display substrate includes a display area and a digging area inside the display area for placing sensor devices; the display area includes a surrounding area. In the first area of the digging area and the second area except the first area, the density of the first wiring in the first area is greater than the density of the second wiring in the second area; so The display substrate further includes a transparent conductive pattern disposed in the first region, the transparent conductive pattern is located on the side of the base substrate where the first wiring is away from the display substrate, and the transparent conductive pattern is used for receiving The preset signal is coupled with the first traces to reduce the coupling capacitance between the first traces. The display substrate and the manufacturing method thereof, the display device and the driving method thereof provided by the present invention can improve the display effect of the display device.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a display substrate and a manufacturing method thereof, and 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-screen (for example: Liu Haiping). display devices such as figure 1 shown ( figure 1 In the middle, A is the display area, and B is the digging area). This method can make the screen ratio higher and is favored by consumers. [0003] In the prior art, since a sensor device is placed in the display screen, part of the display area will be sacrificed, resulting in the deformation of the grid lines and data lines in the display substrate, which reduces the uniformity of pixel charging, resulting in poor display effect of the display device. good. SUMMARY OF THE INVENTION [0004] Embodiments of the present inve...
