Embodiment Construction
[0044] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0045]In related technologies, in order to increase the screen-to-body ratio of a full-screen display device while ensuring a high light transmittance in the hole-digging area in the array substrate, the signal lines used to connect each column of sub-pixels in the array substrate (the signal line is also called data lines) need to be distributed in the winding area outside the hole-digging area, and because the area of the winding area is small, the signal lines in the winding area are usually arranged in a double-layer wiring manner.
[0046] Please refer to figure 1 with figure 2 , figure 1 It is a top view of the hole-digging area and the wiring area in the array substrate provided by the related art, figure 2 yes fig...

The invention discloses an array substrate, a manufacturing method thereof and a display device, and belongs to the technical field of display. A substrate in the array substrate is provided with a hole digging area and a winding area arranged around the hole digging area, and in a first signal line and a second signal line which are loaded with voltages with the same polarity, orthographic projection parts of a first winding wire and a second winding wire located in the winding area on the substrate coincide. Therefore, in the winding area, the distance between the two signal lines loading the voltages with opposite polarities is increased, and the generated parasitic capacitance is small. When the sub-pixels in the array substrate are charged in a time-sharing manner, the influence of the voltage loaded on the signal line connected with the sub-pixels which are charged firstly on the voltage loaded on the signal line connected with the sub-pixels which are charged later is small, the voltage loaded on the signal line connected with the sub-pixels which are charged firstly is not greatly reduced, the charging rate of the sub-pixels is increased, and the charging efficiency of the sub-pixels is improved. The phenomenon that dark vertical lines appear on a display picture of the array substrate is avoided, and the display effect of the array substrate is improved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] Due to the high screen-to-body ratio of the full-screen display device (generally reaching 80% or even more than 90%), the size of the display screen can be increased without increasing the overall size of the display device. Usually, the display surface of a full-screen display device needs to place various light-sensitive sensors such as cameras or light sensors. In order not to affect the screen-to-body ratio of the full-screen display device, corresponding The digging hole, the photosensitive surface of the photosensitive sensor faces the digging hole. In this way, ambient light can enter the photosensitive surface of the photosensitive sensor after passing through the dug holes of the array substrate, so that the photosensitive sensor can work normally.
