Abstract:
A system, circuit, and method for implementing a low power common electrode voltage for a display (e.g., LcoS display) having transistors with low to moderate breakdown voltages may include a first and a second low voltage amplifier, wherein the first amplifier generates a pixel voltage and the second amplifier generates a predetermined voltage. The circuit may include a common electrode circuit coupled to the first and second amplifier to generate a common electrode voltage. Particularly, the circuit may include a control circuit coupled to the common electrode circuit, wherein, during a first phase, the control circuit selectively controls the common electrode circuit to generate a low common electrode voltage based upon a negative value of the predetermined voltage. Further, during a second phase, the control circuit selectively controls the common electrode circuit to generate a high common electrode voltage based upon the sum of the predetermined voltage and the pixel voltage.
