1. display device has:

  • A plurality of sweep traces,A plurality of data lines,A plurality of public supply lines andA plurality of pixels, these pixels are corresponding to the crossover location of above-mentioned a plurality of sweep traces and a plurality of data lines, and each pixel in described a plurality of pixels has;

    Corresponding to the light-emitting component between pixel electrode of described each pixel and the opposite electrode relative with described pixel electrode, when flowing through DC current between pixel electrodes and above-mentioned opposite electrode, described light-emitting component is luminous;

    The 1st transistor, its grid are connected on the corresponding scanning line of described a plurality of sweep traces, the described the 1st transistorized source electrode with the drain electrode in any electrode be connected with a corresponding data line of described a plurality of data lines;

    Keep electric capacity for one, be used for keeping the picture signal that provides described the 1st transistor to provide through at least one data line of described data line, described electric capacity and described the 1st transistor drain kept is connected with another electrode in the source electrode;

    WithThe 2nd transistor is used for being controlled at the conducting between the public supply lines of correspondence of described pixel electrode and described a plurality of public supply lines;

    Described the 2nd transistor is the p channel transistor;

    Wherein in the luminous luminescence process of described light-emitting component, the potential setting of the public supply lines of described correspondence is at the current potential higher than described opposite electrode;

    In described luminescence process, the current potential of described pixel electrode is higher than the current potential of described opposite electrode.
