Problems solved by technology

Furthermore, the number of channels required by the single-layer ITO structure is very large, which will lead to high line impedance, and the X-axis and Y-axis sensing electrodes are likely to form an excessively large bonding area on a flexible circuit board.

Abstract

A touch-sensing electrode structure includes multiple first electrodes and multiple second electrodes. Each first electrode includes a longitudinal part extending in a first direction and multiple branch parts connected to the longitudinal part. The second electrodes are disposed on at least one side of each longitudinal part, and each of the second electrodes at least spreads over a region between two adjacent branch parts of each of the first electrodes. Through the invention, the inductive capacitance of the touch-sensing electrode structure and the sensitivity of the touch control operation can be improved, and the effect of touch-sensing linearity can be improved, and channels required by a single-layer touch-sensing structure and line impdedance can be reduced.

Description

technical field [0001] The invention relates to a touch sensing electrode structure and a touch device. Background technique [0002] At present, the touch sensing electrode structure of the capacitive touch device is usually formed by double-side ITO (double-side ITO) or single-side ITO (single-side ITO) process. In a double-sided ITO process, it is necessary to perform coating and lithographic etching processes on both sides of the glass substrate to form X-axis and Y-axis sensing electrodes on both sides of the glass substrate. It is easy to cause the yield rate to drop. In addition, in a single-sided ITO process, the X-axis and Y-axis sensing electrodes are formed on the same side of the glass substrate. Due to the need for cross-bridge structure design in the plane, the X-axis and Y-axis sensing electrodes are prone to instability due to the material properties of the organic insulating layer. or other factors causing short circuit or open circuit problems. Therefore...
