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

  • luminescent device, drive control module, reset control module, charge control module, and light emitting control module;

    Wherein,The control end of described reset control module is connected with reset signal end, and input end is connected with the first level signal end, and output terminal is connected with the output terminal of described drive control module and the input end of described luminescent device respectively;

    For described luminescent device being resetted under internal compensation pattern, externally under compensation model, derive that described drive control module drives the current signal of described luminescent device and with default standard current value comparison to determine compensating factor;

    The control end of described charge control module is connected with sweep signal end, and input end is connected with data-signal end, and output terminal is connected with the first input end of described drive control module;

    For described drive control module being charged and data writing signal under internal compensation pattern, externally under compensation model to described drive control module data writing signal;

    The control end of described light emitting control module is connected with luminous signal end, and input end is connected with second electrical level signal end, and output terminal is connected with the second input end of described drive control module;

    For described drive control module being charged under internal compensation pattern and controlling described drive control module, drive described luminescent device luminous, externally under compensation model, control described drive control module and drive described luminescent device luminous;

    The output head grounding of described luminescent device.
