Embodiment Construction

[0021] see figure 2 , figure 2 It is a structural schematic diagram of the first embodiment of a touch screen of the present invention. In this embodiment, the touch screen 100 includes a plurality of first conductive lines 11 extending along a first direction X, and a plurality of second conductive lines 12 extending along a second direction Y. One of the two conductive lines is used to input the driving signal, and the other is used to receive the detection signal, that is, the driving electrode Tx is set in the first conductive line 11, and the detection electrode Rx is set in the second conductive line 12; or, the first conductive line 11 The detecting electrode Rx is provided in the middle, and the driving electrode Tx is arranged in the second wire line 12 . During touch detection, the mutual capacitance change at the junction of two conductive lines or the self-capacitance change of each conductive line is detected, that is, the position of the touch point is obtain...

Abstract

The invention discloses a touch screen and a mobile terminal. The touch screen comprises a first conducting circuit which extends along the first direction and a second conducting circuit which extends along the second direction and is overlapped with the first conducting circuit in an insulating mode; the first conducting circuit comprises a plurality of first sensing electrodes arrayed in the first direction at intervals and first connecting bridges for connecting each two adjacent first sensing electrodes; the second conducting circuit comprises a plurality of second sensing electrodes arrayed in the second direction at intervals and second connecting bridges for connecting each two adjacent second sensing electrodes; each first sensing electrode comprises a pointed end towards a third direction, and the pointed end is overlapped with the second sensing electrode in an insulating mode. The charge of the touch screen is gathered at the pointed end, and current is generated through point discharge and the second sensing electrodes to timely release static electricity.

Description

technical field [0001] The invention relates to a touch screen and a mobile terminal. Background technique [0002] The touch screen has many advantages such as fast response speed, accurate positioning, multi-touch support, and long service life, and is widely used in mobile terminals. In order to make users more comfortable to use, the substrate size of the touch screen is increased and the resolution is further improved. Correspondingly, in the manufacturing process, the probability of electrostatic damage to the touch screen is getting higher and higher. Not only that, during the use of the touch screen, the touch screen occurs Friction can also generate charges, and the static electricity formed by the accumulation of charges can easily be mistaken for the touch screen being touched, and then cause false triggers. Therefore, generally, an ESD (electrostatic discharge) circuit needs to be provided in the touch screen, so that the accumulated charge can be released safel...
