<p>PROBLEM TO BE SOLVED: To provide a display incorporated type tablet device capable of securing sufficient display contrast in a high resolution display device. SOLUTION: A display controller 105 scans segment electrode groups S1 to Sm and common electrode groups C1 to Cn entirely in a display period within one frame, and also, a coordinates detection controller 115 successively outputs a driving pulse to a part of the segment electrode groups and/or the common electrode groups in a coordinates detection period within one frame, performs a part of coordinates detection and repeats the coordinates detection of plural frames.</p> |
