1. A display system comprising:

  • a pixel array including a plurality of pixel circuits arranged in row and column, the pixel circuit having a light emitting device, a capacitor, a switch transistor and a drive transistor for driving the light emitting device, the pixel circuit including a path for programming, and a second path for generating the threshold of the drive transistor;

    a first driver for providing data for the programming to the pixel array; and

    a second driver for controlling the generation of the threshold of the drive transistor for one or more drive transistors, the first driver and the second driver driving the pixel array to implement the programming and generation operations independently.
