Abstract
The present disclosure discloses a touch input device including a plurality of driving electrodes and a plurality of sensing electrodes that are formed on a first surface of a substrate. An improved touch input device (with e.g. reduced area occupied by electrodes or improved touch control resolution, and/or decreased number of driving electrode leads) is provided by 1) divisionally using the sensing electrode in a horizontal direction; and optionally 2) further divisionally using the driving electrode in the column direction. One sensing electrode which is divisionally used in a row direction can be further split into two adjacent sub-sensing electrodes in the row direction. Also disclosed is a touch display device including the touch input device.
