DISPLAY DEVICE WITH TOUCH DETECTION FUNCTION, DRIVING METHOD, AND ELECTRONIC APPARATUS |
摘要 |
<p>PROBLEM TO BE SOLVED: To obtain a display device with touch detection function capable of reducing a frame edge area on the side vertical to the display scanning direction, a driving method and an electronic apparatus.SOLUTION: The display device with touch detection function 1 includes: a plurality of signal lines (pixel signal line SGL) juxtaposed extending in one direction; a plurality of common driving electrodes (driving electrode COML) juxtaposed extending along the signal lines; a display element (liquid crystal element LC) inserted between each pair of signal lines and common driving electrodes so as to be connected with the pair; a plurality of touch detection electrodes TDL juxtaposed extending in a direction crossing the common driving electrodes, configured to form an electrostatic capacitance in each crossing portion; a driving unit (source driver 13 and driving electrode driver 14) to drive the signal lines and the common driving electrodes; and a detection processing unit (touch detection circuit 40) to detect an external proximity object, based on touch detection signals Vdet output from the touch detection electrodes in accordance with the drive of the common driving electrodes.</p> |
