Abstract
Described herein are light emitting element driver integrated circuits (ICs), methods for use with light emitting element driver ICs, and projector systems that include a light emitting element driver IC. A light emitting element driver IC receives a color data word from the video processor IC. Starting with the color data word received from the video processor IC, the light emitting element driver IC performs a gamma expansion function to thereby produce a gamma expanded digital or analog signal. Additionally, the light emitting element driver IC outputs, in dependence on the generated gamma expanded digital or analog signal, a gamma expanded analog drive signal for driving the light emitting element.
