Touch screen and electronic device

Abstract

The invention provides a touch screen which comprises: a base material, wherein the base material is provided with a first surface and a second surface opposite to the first surface; a conducting layer which is arranged on the first surface of the base material, wherein the conducting layer comprises an induction area and a non-induction area, and the non-induction area is provided with a signal line; a shielding layer which is arranged on the second surface of the base material, wherein the shielding layer is provided with a ground wire, and the projection of the signal wire on the shieldinglayer partially coincides with the ground wire. According to the scheme, the ground wire is arranged at the position, corresponding to the signal wire, of the shielding layer, so that the width of thenon-induction area is reduced, and a narrow frame is achieved. The invention further provides an electronic device which comprises the touch screen.

Description

technical field [0001] The invention relates to a touch screen and an electronic device. Background technique [0002] With the continuous advancement of technological development, electronic devices such as mobile phones, tablet computers, and smart watches have gradually become indispensable communication and entertainment tools in people's lives, and touch screens are essential components of various electronic devices. [0003] At present, most touch screens of mobile terminals are capacitive touch screens, and there are two schemes of self-capacitance and mutual capacitance. Please also refer to figure 1 and figure 2 , the traditional self-capacitive capacitive touch screen 100' includes a substrate 20', and a conductive layer 40' disposed on one side of the substrate 20', the conductive layer 40' includes a sensing area 42' and a non-sensing area 44', the non-sensing area 44' The sensing area is provided with a signal line 442' and a ground line 444' electrically co...
