Patent ID: 8766898

Claim:
A differential pixel-driver circuit, comprising: a first circuit to receive a multi-bit digital input, first and second clock signals having non-overlapping enable phases, and a second pixel-drive output voltage, the second pixel-drive output voltage being coupled to the first circuit via a switch enabled during the enable phase of the first clock signal, and generate a first pixel-drive output voltage as a function of the received multi-bit digital input and the second pixel-drive output voltage, the first circuit including a digital-to-analog converter (DAC) configured to receive different values of the multi-bit digital input during respective non-overlapping enable phases of the first and second clock signals; a second circuit to generate the second pixel-drive output voltage; and output terminals to provide the first and second pixel-drive output voltages to differentially drive a pixel according to a difference between the first and second pixel-drive output voltages.
