Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] The symbol " / " in this document indicates that the associated object is an or relationship, for example, A / B indicates A or B.

[0020] The terms "first" and "second" in the specification and claims of the present invention are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first conductor line and the second conductor line are used to distinguish different conductor lines, rather tha...

Abstract

The embodiment of the invention discloses a mobile terminal and a driving method, which relate to the technical field of communication, and aim to solve the problem that the liquid adhered to the edgearea of a capacitive touch screen reduces the accuracy of the mobile terminal in identifying the touch input of a user. The mobile terminal comprises a touch screen and a control module. The touch screen comprises a conductor line and a plurality of touch sensing units. The control module is configured to input a driving signal to each of the conductor line and the plurality of touch sensing units in a touch scanning phase in a scanning cycle of the touch screen, and a driving signal of one touch sensing unit is configured to drive the one touch sensing unit to sense a touch input of a user,wherein the potential difference between the conductor line and each of the touch sensing units is zero after the driving signal is inputted to the conductor line and each of the touch sensing units.The mobile terminal may be applied to a scene that identifies the touch input of the user.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a mobile terminal and a driving method. Background technique [0002] With the development of communication technology, capacitive touch screens are more and more widely used in mobile terminals, and liquid attached to the capacitive touch screen may cause the mobile terminal to misidentify the liquid as a user's touch input. [0003] At present, synchronous driving signals can be input to each capacitive sensor of the capacitive touch screen to solve the above-mentioned misidentification problem. For example, if figure 1 As shown, when the liquid 10 is attached to the two capacitive sensors 11 at the same time, since the potential difference between the two capacitive sensors 11 is 0, there will be no capacitance change between the two capacitive sensors 11, Therefore, the mobile terminal will not misidentify the liquid as the user's touch i...
