Title:
TOUCH PANEL AND TOUCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/051075
Kind Code:
A1
Abstract:
The present disclosure provides a touch panel and a touch device. The touch panel comprises a touch function area and an electrode layer located in the touch function area, and the electrode layer comprises a plurality of first electrodes arranged in parallel and a plurality of second electrodes arranged in parallel. The second electrodes are arranged to be spaced apart from the first electrodes, and intersect with the first electrodes to form touch units at the intersections. In at least one touch unit, the first electrode comprises at least one first main electrode and at least one first sub-electrode connected to the first main electrode, and the extension direction of the first sub-electrode is arranged to be parallel with the extension direction of a touch channel determined by at least one of the first electrode and the second electrode. The extension direction of the first sub-electrode is designed according to the extension direction of the touch channel determined by the first electrode or the second electrode. Therefore, changes in touch precision and sensitivity are prevented from being too large in a case that a touch angle is deflected, and the problems of reduction in touch precision and sensitivity are mitigated.
