Claim Text:
1. An electronic paper touch device, comprising: a first substrate; a first electrode layer located on said first substrate; an electronic paper display layer located on said first electrode layer; a transparent electrode layer located on said electronic paper display layer and having plural transparent electrodes, and said electronic paper display layer includes plural display structures, and said display structure is selected from a group consisting of a micro capsule, a micro cup, and a rotatable ball; a second substrate located on said transparent electrode layer; a control unit having a touch detection unit and an electronic paper voltage source, wherein, when said control unit is in a touch mode, said control unit will disconnect said electronic paper voltage source from said first electrode layer and said transparent electrode layer, and couple said touch detection unit with said first electrode layer and with said transparent electrode layer to perform a capacitive touch detection procedure; and when said control unit is in an electronic paper mode, said control unit will disconnect said touch detection unit from said first electrode layer and said transparent electrode layer, and couple said electronic paper voltage source with said first electrode layer and with said transparent electrode layer to perform an image write-in procedure; and said electronic paper mode has a first active time, said capacitive touch detection procedure has a second active time, and said first active time is longer than said second active time; and
