ABSTRACT:
Systems and methods for providing threshold voltage compensation of pixels are provided. A representative system incorporates first switching element and a voltage compensation driver. The first switching element is operative to transfer a data signal. The voltage compensation driver is operative to generate a compensation voltage according to a reference signal and output a driving current according to the data signal and the compensation voltage.
