Touch processor and touch method

Abstract

The invention provides a touch processor and a touch method. The touch processor is electrically coupled to the touch panel, and the touch panel includes M driving electrodes and N sensing electrodes to perform the following steps: determine at least one first driving electrode and at least one first external object touched or approached by the first external object first sensing electrodes; and performing first mutual capacitance detection on X strips of the driving electrodes and Y strips of the sensing electrodes, wherein the X strips of driving electrodes include the at least one first driving electrode, and the Y strips of sensing electrodes include the at least one first driving electrode. For the at least one first sensing electrode, X is smaller than M, and Y is smaller than or equal to N.

Description

technical field [0001] The present invention relates to a touch processor and a touch method, in particular to a touch processor and a touch method for detecting the movement of an external object. Background technique [0002] The existing known mutual capacitive sensor (mutual capacitive sensor) includes an insulating surface layer, a first conductive layer, a dielectric layer, and a second conductive layer, wherein the first conductive layer and the second conductive layer have a plurality of first conductive layers respectively. strips and second conductive strips, these conductive strips may be composed of a plurality of conductive strips and connection lines of series conductive strips. [0003] When performing mutual capacitance detection, one of the first conductive layer and the second conductive layer is driven, and the other of the first conductive layer and the second conductive layer is detected. For example, the driving signal is provided to each first conduct...

Problems solved by technology

[0005] However, if a conductive substance crosses more than two conductive strips on the insulating surface, the capacitance image may change due to the capacitive coupling between the conductive substance and the conductive strip when it is not approached or covered by an external conductive object. resulting in misjudgment

For example, when water stains cross two or more conductive strips on the insulating surface, the capacitance value image will change, mistakenly thinking that there is a finger touching

[0006] This shows that above-mentioned prior art obviously has inconvenience and defective, and extremely waits to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
