1. a dot structure is applicable in the touching-type monitor, and said touching-type monitor comprises the transistor of a plurality of electrical connection electric capacity, it is characterized in that, said dot structure comprises:

  • First signal wire of disposed adjacent and secondary signal line, wherein said secondary signal line is a signal read line, the one of which end is electrically connected with signal driver, and its other end with read circuit and be electrically connected;

    The first grid polar curve of disposed adjacent and second grid line, wherein said second grid line is electrically connected the transistorized gate terminal of a plurality of electrical connection electric capacity of said touching-type monitor;

    Photistor is used to produce the photoinduction signal;

    The first transistor, the gate terminal of this first transistor are connected to first grid polar curve and its drain electrode end is connected to first signal wire;

    Transistor seconds, the 3rd end that it has first end that is electrically connected with said second grid line, second end that is electrically connected with the drain electrode end of said photistor and is electrically connected with said secondary signal line;

    Storage capacitors, an end of this storage capacitors is connected to the source electrode of said the first transistor;

    And, the common line between said first grid polar curve and said second grid line electrically connects the source terminal and the gate terminal of the other end and the said photistor of this storage capacitors respectively,Wherein, Said first signal wire is electrically connected to the wherein transistor drain end in the transistor of said a plurality of electrical connection electric capacity;

    And the grid impulse of the transistorized said second grid line through connecting transistor seconds and said a plurality of electrical connection electric capacity is divided into two adjacent parts;

    Be first and second portion;

    Wherein first of the grid impulse through said second grid line partly and second partly have the identical level of polarity, and in the one scan switch periods, the first of said grid impulse is corresponding signal fetch phase;

    And the second portion of said grid impulse is the respective pixel write phase, and the first of the grid impulse through said second grid line and both total pulse widths of second portion are wide through the grid impulse of first grid polar curve.
