Abstract

A self capacitive type touch control device comprises a plurality of first electrode pad series, a plurality of second electrode pad series, a plurality of third electrode pad series and a plurality of fourth electrode pad series, wherein each first electrode pad series comprises a plurality of first electrode pads of which the areas are gradually increasing in sequence; each second electrode pad series comprises a plurality of second electrode pads of which the area is gradually increasing in sequence; each adjacent first electrode pad and second electrode pad are arranged in an alternating manner; each third electrode pad series comprises a plurality of third electrode pads of which the area is gradually increasing in sequence; each fourth electrode pad series comprises a plurality of fourth electrode pads of which the area is gradually increasing in sequence; the third electrode pad and the fourth electrode pad, which are adjacent, are arranged in an alternating manner; the last fourth electrode pad of each fourth electrode pad series is adjacent to the last second electrode pad of each second electrode pad series.

Description

technical field [0001] The present invention relates to a touch device, in particular to a self-capacitive touch device and an operating method thereof. Background technique [0002] With the rapid development and application of information technology, wireless mobile communications, and information home appliances, many information products have been transformed from traditional input devices such as keyboards or mice in order to achieve more convenient portability, lighter volume, and more user-friendly operation. To use the touch panel (Touch Panel) as an input device. [0003] At present, touch panels can be mainly divided into two types, one is a resistive touch panel, and the other is a capacitive touch panel. For a resistive touch panel, the user needs to actually apply pressure on the resistive touch panel to make some areas inside the resistive touch panel conduct and generate corresponding coordinate signals. Therefore, the resistive touch panel higher damage rat...
