1. an image element circuit, is characterized in that, comprising:

  • select module, writing module, driver module and luminescent device;

    Wherein,First control end of described selection module is connected with first node, and first input end is connected with the first power supply signal end, and the second control end is connected with second source signal end respectively with the second input end, and output terminal is connected with Section Point;

    The signal of described first power supply signal end or the signal of described second source signal end, under the control of described first node and described second source signal end, are outputted to described Section Point by described selection module;

    The control end of described driver module is connected with described first node, and input end is connected with described Section Point, and output terminal is connected with the input end of described luminescent device;

    Described driver module is used under the control of described first node, and the signal inputted by described Section Point drives described luminescent device luminous;

    The output terminal of described luminescent device is connected with the 3rd power supply signal end;

    First control end of said write module is for inputting the first control signal, second control end is for inputting the second control signal, first input end is connected with data signal end, second input end is connected with reference signal end, first output terminal is connected with described first node, and the second output terminal is connected with the input end of described luminescent device;

    Said write module is used for, under the control of described first control signal, the signal of described data signal end is written to described first node, under the control of described second control signal, carry out initialization by the signal of described reference signal end input to the input end of described luminescent device.
