Touch positioning method and system for projected capacitive and surface capacitive integrated screen

Abstract

The invention provides a touch positioning method and system for a combined projective capacitive and surface capacitive screen. The touch positioning method comprises the following steps: after detecting that a user executes touch operation, obtaining the numbers of electrodes triggered by the current touch operation in a plurality of single electrodes which are arranged in parallel in the touch screen, and obtaining vertical coordinates of touch points corresponding to the current touch operation according to the numbers of the electrodes and a preset Y-shaft positioning algorithm; when an electric field of the touch screen is balanced, obtaining current at receiving ends and emitting ends of the electrodes triggered by the current touch operation, and obtaining transverse coordinates according to the current at the receiving ends and the emitting ends and a preset X-shaft positioning algorithm; positioning the touch points according to the vertical coordinates and the transverse coordinates of the touch points. The touch positioning method and system can be used for accurately positioning the touch operation by obtaining the numbers of the electrodes and the current at the receiving ends and the emitting ends.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a touch positioning method and system for a projected capacitive and surface capacitive integrated screen. Background technique [0002] With the popularity of projected capacitive touch, there are more and more single-layer touch solutions, such as Figure 1a and Figure 1b Shown are the schematic diagrams of "T"-shaped single-layer capacitors and triangular single-layer capacitors, respectively. However, all single-layer touch solutions cannot be separated from the reprocessing of the conductive film, and there are secondary pollutions caused by chemical etching and chemical cleaning during the processing. Moreover, at present, it is still impossible to precisely position the touch point on the touch screen after directly performing secondary coating on the formed conductive film. [0003] Therefore, the prior art still needs to be improved and developed. Conte...
