Abstract:
A touch panel includes a base, which is a liquid crystal module serving as a ground; a flexible dielectric layer over the base; and a one-dimensional pattern layer with sensor cells positioned as the same layer over the flexible dielectric layer. The sensor cells form a sensor array, and each of the sensor cells is individually controlled and sensed via an independent sensing line, wherein press sensing control is conducted according to a capacitance change resulting from a distance change between the sensor array and the base in response to an external force, and touch or gesture-based sensing control is conducted according to a capacitance change in the sensor array without involving the base.
