Abstract

We have investigated the use of segmented red, green, and blue LED emitters for use in LCoS projection systems. We find that segmenting the light emitting area has a minimal impact to the efficacy and wall plug efficiency of the die thus validating that these devices could help in significantly reducing the power consumption of LCoS systems by enabling local dimming strategies.
