<p><P>PROBLEM TO BE SOLVED: To provide an electrooptical device capable of performing touch determination in high accuracy, an electronic apparatus using the same and a contact detection method therefor. <P>SOLUTION: A plurality of sensing circuits are provided in a pixel area to detect the capacity value of a capacity element for contact detection. A control circuit stores, as a reference capacity data, a capacity value for one screen that is detected in a reference state that an object is not in contact with a screen. In addition, the control circuit stores, as object capacity data, a capacity value for one screen that is detected when the touch input function is in an on-state. The control circuit creates differential data between the reference capacity data and the object capacity data so as to determine whether or not the object is brought into contact with the screen on the basis of the differential data. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
