Display substrate, display panel and display device

Abstract

An embodiment of the invention provides a display substrate, a display panel and a display device, and relates to the field of display technologies. The display substrate comprises a plurality of touch control electrodes and an integrated circuit. Every touch control electrode is electrically connected with the integrated circuit by a main lead wire; the touch control electrode, which is the farthest away from the integrated circuit, among every row of touch control electrodes is further correspondingly provided with x1 auxiliary lead wires, the touch control electrode, which is the closest to the integrated circuit, among every row of touch control electrodes is correspondingly provided with x2 auxiliary lead wires, and the x1 is larger than the x2; every two optional adjacent touch control electrodes among the other touch control electrodes, except for the touch control electrode farthest away from the integrated circuit and the touch control electrode closest to the integrated circuit, among every row of touch control electrodes are correspondingly provided with x3 auxiliary lead wires and x4 auxiliary lead wires in the direction from far to close to the integrated circuit, the x3 is larger than or equal to the x4, the x1 is larger than or equal to the x3, and the x4 is larger than or equal to the x2; the corresponding auxiliary lead wires of the touch control electrodes are electrically connected with the main lead wires corresponding to the touch control electrodes in a peripheral area. According to the technical scheme, the display substrate, the display panel and the display device have the advantage that the touch control performance of the display substrate can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display panel and a display device. Background technique [0002] With the rapid development of display technology, users have higher and higher demands on the performance of display devices, and display panels with touch functions emerge as the times require. Such as figure 1 as shown, figure 1 The top view of the display substrate provided in the prior art, the display substrate included in the display panel is provided with a plurality of touch electrodes 1' and a plurality of leads 2', and each touch electrode 1' is connected to an integrated circuit IC through a lead 2' electrical connection, the inventors of the present application have found that in the prior art, in each column of touch electrodes 1', the touch electrode 1a' that is farthest from the integrated circuit has a longer corresponding lead wire 2', and the lead wire 2' The res...

like figure 1 as shown, figure 1 The top view of the display substrate provided in the prior art, the display substrate included in the display panel is provided with a plurality of touch electrodes 1' and a plurality of leads 2', and each touch electrode 1' is connected to an integrated circuit IC through a lead 2' electrical connection, the inventors of the present application have found that in the prior art, in each column of touch electrodes 1', the touch electrode 1a' that is farthest from the integrated circuit has a longer corresponding lead wire 2', and the lead wire 2' The resistance of the touch electrode 1a' is large, and the loss of the signal transmitted between the integrated circuit IC and the touch electrode 1a' is relatively large, so that the accuracy of the touch electrode 1a' (the degree of closeness between the measured value and the true value) is low, and the distance The touch electrode 1b' closest to the integrated circuit IC has a shorter length corresponding to the lead wire 2', the resistance of the lead wire 2' is smaller, and the loss of the signal transmitted between the integrated circuit IC and the touch electrode 1b' is relatively small. Furthermore, the precision of the touch electrode 1b' is relatively high, resulting in poor touch uniformity of the display substrate, resulting in poor touch performance of the display substrate
