Brightness control drive circuit for a current-driven display device

A current-driven display device (10) includes sub-pixel drive circuits (12, 12', 12") with integral photo-sensitive circuits (30) that modify the respective sub-pixel drive currents as a function of the locally sensed ambient light level. The photo-sensitive circuit (30) may include a phot...
