Patent ID: 8330880

Claim:
A reflective type touch-sensing display panel, comprising: a front substrate having an inner surface and an outer surface opposite to the inner surface; a plurality of scan lines disposed on the inner surface of the front substrate; a plurality of data lines disposed on the inner surface of the front substrate and intersected with the scan lines; a plurality of pixel structures, disposed on the inner surface of the front substrate, each of the pixel structures being electrically connected to one of the scan lines and one of the data lines correspondingly, and each of the pixel structures comprising: a switch device electrically connected to one of the scan lines and one of the data lines correspondingly; a pixel electrode electrically connected to the switch device; and a transparent storage capacitance electrode layer disposed on the inner surface of the front substrate and sandwiched between the pixel electrode and the front substrate; a plurality of photo-sensors disposed on the inner surface of the front substrate, each of the photo-sensors comprising: a transparent lower electrode disposed on the inner surface of the front substrate; a photo-sensitive silicon-rich dielectric layer disposed on the transparent lower electrode; and an upper electrode disposed on the photo-sensitive silicon-rich dielectric layer; a plurality of readout devices, each of the readout devices being electrically connected to one of the photo-sensors correspondingly; a rear substrate disposed opposite to the front substrate; and a reflective display medium sealed between the front substrate and the rear substrate, wherein the photo-sensors are disposed between the front substrate and the reflective display medium; and wherein the transparent storage capacitance electrode layer of the pixel structure and the transparent lower electrode of the photo-sensor are made of a same layer.
