Embodiment Construction

[0035] Please refer to figure 1 , figure 1 A schematic flow chart showing a touch detection method according to an embodiment of the present invention. The touch detection method of this embodiment is applicable to a touch panel. The steps of the touch detection method include: in step S110, performing mutual capacitive touch detection on the touch panel, and then, in step S120, performing self-capacitive touch detection on the touch panel. The mutual-capacitive touch detection and the self-capacitive touch detection performed in step S110 and step S120 are respectively the mutual-capacitive detection results and the self-capacitive detection results. In step S130, calculations are performed on the mutual-capacitance detection results and self-capacity detection results respectively generated in steps S110 and S120 to obtain position information of one or more touch points on the touch panel .

[0036] It should be noted that the mutual capacitive touch detection and self ...

Abstract

The invention discloses a touch-control device and a touch-control detecting method thereof. The touch-control detecting method is applicable to a touch-control panel, wherein the touch-control panel is provided with a plurality of touch-control lists and a plurality of touch-control rows. The touch-control detecting method comprises the following steps: carrying out mutual capacitance type touch-control detection and self-containing touch-control detection in an alternative manner for the touch-control panel, respectively obtaining mutual capacitance detection results and self-containing detection results, and then calculating so as to obtain position information of at least one touch-control point on the touch-control panel according to the mutual capacitance detection results and the self-containing detection results.

Description

technical field [0001] The present invention relates to a touch device and a touch detection method thereof, in particular to a touch device implementing a composite touch detection method. Background technique [0002] With the advancement of electronic technology, electronic products have become an indispensable and important tool in people's life. In order to improve the convenience of controlling the electronic products, operating the electronic products through the touch panel has become the mainstream of the electronic products. Therefore, accurately and quickly detecting the touch operation performed by the user on the electronic product is an important issue of the current electronic product. [0003] In an existing touch device, the controller scans each touch channel or each intersecting point between touch panels one by one when determining whether a touch event occurs or not. Today, the demand for multi-touch has become a necessary function, such a touch detect...
