Patent ID: 6998788

Claim:
A method of controlling current to a pixel, comprising: a. connecting a separate data driver to each output of a horizontal shift register, each data driver further comprising a V GS storage device and a switching circuit operatively connected to the output of the horizontal shift register; b. connecting each data driver to a digital data controlling current source/sink; c. providing a digital logic signal from each output of the horizontal shift register to each corresponding data driver; d. providing a digital control signal from the digital data controlling current source/sink to each corresponding data driver; e. allowing current to flow through each data driver to the digital data controlling current source/sink upon the presence of a high digital signal from the digital data controlling current source/sink at that data driver; f. allowing current to be impeded through each data driver to the digital data controlling current source/sink upon the presence of a low digital signal from the digital data controlling current source/sink at that data driver; g. maintaining a gate-to-source voltage V GS at a predetermined transistor component of each switching circuit upon the high digital signal from the digital data controlling current source/sink at that data driver; and h. allowing the gate-to-source voltage V GS at the predetermined transistor component of each switching circuit to discharge upon the low digital signal from the digital data controlling current source/sink at that data driver.
