Patent Images

1. , a kind of display device comprises:

  • A plurality of pixels are arranged to matrix;

    Pixel electrode is provided as and corresponds respectively to described a plurality of pixel;

    The individual counter electrode of n (n 〉

    =2) is provided with along the direction of scanning that direction is set as of described a plurality of pixels with respectively apart from each other in the face of described pixel electrode, and extends along another direction of this direction of scanning that intersects vertically;

    The Presentation Function layer has respectively the function of display image according to being applied to the described pixel electrode that faces with each other and the voltage between a described n counter electrode;

    Write the driven sweep part, repeat the operation that the signal voltage that will be used to show is written to the pixel electrode that is arranged on the predetermined quantity on this other direction, and on this direction of scanning, repeat the conversion operations that is used for switching in turn as the pixel electrode of this predetermined quantity that writes target of the signal voltage that is used to show;

    Detecting electrode has electrostatic capacitance separately between a described n counter electrode and described detecting electrode;

    The AC driving sweep test is used for the individual counter electrode of s (n>

    s 〉

    =1) of the described n of an AC driving counter electrode, and along with this conversion operations of partly being carried out by described driven sweep is changed this s counter electrode;

    AndThe test section is used for detecting because of the influence of the external capacitive variation at the voltage of each this AC driving that causes of described detecting electrode.
