Embodiment Construction

[0035] Please refer to figure 1 , figure 1 A schematic flowchart of a touch detection method according to an embodiment of the present invention is shown. The touch detection method of this embodiment is suitable for touch panels. 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 self-capacitive touch detection performed in step S110 and step S120 respectively obtain the mutual-capacitive detection result and the self-capacitive detection result. In step S130, perform calculations on the mutual-capacitive detection results and self-capacitive detection results generated in steps S110 and S120, respectively, to obtain position information of one or more touch points that occur on the touch panel .

[0036] It is worth noting 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 that executes a composite touch detection method. Background technique [0002] With the advancement of electronic technology, electronic products have become indispensable and important tools in people's lives. In order to improve the control convenience of electronic products, operating electronic products through touch panels has become the mainstream of electronic products. Therefore, accurately and quickly detecting the touch operation performed by the user on the electronic product is an important issue for the electronic product at this stage. [0003] In the existing touch devices, the controller of the controller scans each touch channel or each interlaced point between the touch panels one by one when a touch event occurs or not. Today, when the demand for multi-touch becomes a necessary function, such a touch detection method must...
