Original Abstract Submitted

A pixel level-shifter for driving a pixel of a display has a reduced power consumption and a reduced size. The pixel level-shifter includes an internal reference voltage generator that receives an external reference voltage signal and generates an internal reference voltage signal based on the external reference voltage signal. A level-shifting circuit receives a low voltage pixel output signal and generates a boosted drive signal based on the low voltage pixel output signal and the internal reference voltage signal. A first transistor circuit is coupled between a high voltage pixel supply voltage node and a pixel electrode node and includes a control node coupled to receive the boosted drive voltage signal. The first transistor circuit controls application of a high voltage pixel supply voltage signal on the pixel electrode node in response to the boosted drive signal.
