ABSTRACT:
A display that includes a circuit to receive pixel data and to generate a first set of gray-scale voltages based on the first set of reference voltages to drive pixel circuits to display respectively different gray-scale levels during a first time period in accordance with the pixel data, and generate a second set of gray-scale voltages based on a second, different set of reference voltages to drive the pixel circuits to display a common gray-scale level during a second time period. For example, the common gray-scale level can be a black level.
