Patent ID: 8497835

Claim:
An electro phoretic display (EPD) device including a touch panel, comprising: first and second substrates facing each other; a plurality of gate lines, a plurality of common lines, and a driving voltage line on the first substrate in a first direction; an output line and a plurality of data lines defining pixel regions by crossing the gate lines, wherein the output line and the data lines are in a second direction crossing the first direction; pixel transistors formed at intersecting parts between the respective gate lines and the data lines; a pixel electrode at each pixel region, wherein the pixel electrode includes a single layer comprising a reflective electrode; a sensing transistor between one of the common lines and the driving voltage line; an output transistor between one of the gate lines, adjacent to the sensing transistor, and the sensing transistor to transmit an output signal to the output line; a sensing capacitor between one of the common lines and a connection part between the sensing transistor and the output transistor; a common electrode over the entire surface of the second substrate; and an electro phoretic layer between the first and the second substrates, wherein the common lines are overlapped with the pixel electrode at pixel regions.
