Abstract: A touch substrate includes a first layer wiring group and a second layer wiring group that are located in a peripheral region. The first layer wiring group includes a plurality of first wirings, the second layer wiring group includes a plurality of second wirings, and a square resistance of a first wiring is greater than a square resistance of a second wiring. The peripheral region includes a first wiring region provided with at least one first-type touch lead therein and a second wiring region provided with at least one second-type touch lead therein. Each first-type touch lead includes a first wiring and a second wiring that are connected to each other and whose orthographic projections on the touch substrate are overlapped. Each second-type touch lead includes a second wiring or a first wiring. A length of the first-type touch lead is greater than a length of the second-type touch lead.

Abstract: Disclosed is a display substrate including a display region which includes multiple pixel columns and multiple data signal lines, and a binding region which includes multiple detection units; the multiple pixel columns include first pixel columns and second pixel columns, the multiple data signal lines include first data signal lines which are electrically connected with multiple sub-pixels in the first pixel columns, and second data signal lines which are electrically connected with multiple sub-pixels in the second pixel columns; each detection unit include a first switch unit, a second switch unit, a third switch unit, a first transmission line and a second transmission line, the first switch unit is connected to the corresponding first data signal line by means of the first transmission line, and the second switch unit and the third switch unit are connected to the corresponding second data signal line by means of the second transmission line.

Abstract: An array substrate has a display area and a peripheral area. The array substrate includes a substrate, a first common voltage line disposed on a first side of the substrate, and a voltage signal introduction structure disposed on the first side of the substrate. The first common voltage line is located in the peripheral area and arranged along at least part of a boundary of the display area. The voltage signal introduction structure is electrically connected to at least one position except two ends of the first common voltage line, so as to input a voltage signal to the first common voltage line.
