1. A display comprising a plurality of pixels, each pixel comprising:

  • a first transistor having a gate, a source and a drain, where said gate is coupled to a select line, where said source is coupled to a data line;

    a second transistor having a gate, a source and a drain, where said gate of said second transistor is coupled said select line, where said drain of said second transistor is coupled to a VDD line, where said source of said second transistor is coupled to said drain of said first transistor;

    a third transistor having a gate, a source and a drain, where said gate of said third transistor is coupled said select line;

    a capacitor having a first terminal and a second terminal, where said source of said third transistor is coupled to said first terminal of said capacitor, where said second terminal of said capacitor is coupled to said drain of said first transistor;

    a fourth transistor having a gate, a source and a drain, where said source of said fourth transistor is coupled to said drain of said first transistor, where said gate of said fourth transistor is coupled said source of said third transistor; and

    a light element having two terminals, where said drain of said fourth transistor and said drain of said third transistor are coupled to one of said terminal of said light element.
