Problems solved by technology

However, in order to enhance the capacitive sensing signal and avoid delay or failure of the sensing signal, the electrode design of the traditional projected capacitive touch technology still has room for improvement. How to improve the detection precision of the touch device is still a challenge. A major topic in the field of touch

Description

technical field [0001] The present invention relates to a touch device, and in particular to a capacitive touch device. Background technique [0002] At present, the commonly used touch technologies for electronic devices are: resistive, surface capacitive, projected capacitive, surface acoustic wave, optics imaging, infrared ( infrared), refraction (bendingwave) and digital conversion (active digitizer), etc. The first three technologies are suitable for smaller portable devices or consumer electronic products because of their small size and relatively high precision. [0003] As far as resistive touch technology is concerned, there are technical limitations in physical conditions from touching the screen to touch detection, data calculation and position confirmation. For example, contact detection will cause excessive wear and tear in some specific areas due to the constant contact range, which will reduce the conduction efficiency of the conductive film contact. In add...
