Abstract:
1. A method of driving a touch panel-mounted electrophoretic display device, the touch panel-mounted electrophoretic display device including: an electrophoretic element including electrophoretic elements, the electrophoretic element being disposed between one pair of substrates; a plurality of scanning lines and a plurality of data lines; a plurality of pixels arranged at positions corresponding to intersections of the plurality of scanning lines and the plurality of data lines, wherein a first electrode is formed for each of the pixels on one of the substrates, and a second electrode facing the pixel electrodes is formed on the other of the substrates, wherein each of the pixels includes: a pixel switching element that is connected to the scanning line aligned in a first direction and the data line disposed in a second direction; a memory circuit that is connected to the pixel switching element; and a switching circuit that is disposed between the memory circuit and the first electrode, and wherein a first control line and a second control line are connected to the switching circuit, the method comprising: connecting the first control line or the second control line and the first electrode by operating the switching circuit based on the output of the memory circuit, and setting the electric potential of the first control line and the electric potential of the second control line to a first electric potential and a second electric potential, during an operation inputting period in which positional information is input to the touch panel; and inputting an image signal that includes a touch panel signal used for displaying the trajectory of the positional information input to the touch panel in the electrophoretic element to the memory circuit of the selected pixel through the data lines and the pixel switching element by selecting the pixel that is connected to the corresponding scanning line by simultaneously supplying a scanning signal to the plurality of scanning lines in a state in which the electric potential of the second electrode is set to the first electric potential.
