Abstract:
A hybrid pulse-width-modulation pixel includes a light controller responsive to a variable power signal specifying different powers and a pixel controller. The pixel controller is operable receive a pixel luminance signal comprising multiple bits specifying a desired light-controller luminance, generate the variable power signal in response to the pixel luminance signal, and drive the light controller to emit light at different luminances in response to the variable power signal for different time periods. The pixel controller is operable to provide the variable power signal at a constant first power for a first time period and provide the variable power signal at a constant second power different from the constant first power for a second time period.
