Brightness offset error reduction system and method for a display device

摘要

This invention provides a brightness offset error reduction system for a display device, which may have a lighted display panel and control circuitry. The lighted display may be backlit, frontlit, or emissive. The brightness offset error reduction system has voltage divider circuitry for receiving an output voltage from digital-to-analog converter (DAC) circuitry. The voltage divider circuitry provides a fractional portion of the output voltage as a divided output voltage. This division of the output voltage reduces brightness offset errors and may increase the brightness resolution at low luminance levels.
