THIN FILM TRANSISTOR DISPLAY BACKPLANE AND PIXEL CIRCUIT THEREFOR

摘要

Briefly, in accordance with one or more embodiments, a pixel circuit to drive an electro-optical element of a display backplane comprises an element driver coupled to the electro-optical element, a programming switch coupled to the element driver, and a driver switch coupled to the programming switch and the element driver. The driver switch is capable of controlling when the element driver is turned on or turned off, and is capable of pulse-width modulating the drive current provided to the electro-optical element, for example to provide a lower drive current to the electro-optical element.
