PIXEL DRIVER WITH LOW VOLTAGE TRANSISTORS

摘要

An image display system implemented with a spatial light modulator (SLM) comprising a plurality of pixel elements each comprises a driver circuit. The driver circuit further comprises at least a first and second transistors cascaded with a first capacitor between a high voltage (Vh) and a ground voltage (Vg) wherein each of the first and second transistors having a breakdown voltage less than the high voltage (Vh). The first transistor receives an input signal to turn on the first and second transistors for discharging the first capacitor and pulling down an output voltage to a ground voltage (Vg) and to turn off the first and second transistors to pull up the output voltage to the high voltage (Vh) wherein each of the first and second transistor is biased to approximately half of the high voltage (Vh/2).
