Abstract
This invention provides a resolution control system for a display device, which may have a lighted display and control circuitry. The lighted display may be backlit, frontlit, or emissive. The resolution control system may have two or more digital-to-analog converters, which may be provided by digital-to-analog converter (DAC) circuitry in the control circuitry. The DACs convert data values into an output voltage for controlling an operating parameter, which may be brightness, contrast, and the like. The DACs have a cascade arrangement where the output voltage of one DAC is the input voltage of another DAC.
