Electrophoretic display device with photo sensor touch input

摘要: A touch panel electrophoretic display comprising a substrate (101) coupled to an film (141) including charged particles and switching element (Ts) connected gate line data at intersections for controlling pixel electrode (129). First second photo sensor elements (S1, S2) having different channel width and/or length are provided either preferably in each or adjacent pixels (figure 6). The sensors recognizing input by sensing amount of light. Preferably the first has narrow use when peripheral illumination is greater than 1000 Lux wide less as determined switch 160.
