| Abstract: | Based on the low power consumption, long lifespan and high irradiance efficiency of ultra high-bright LED, an application of Liquid Crystal on Silicon (LCoS) light source is proposed. Considering the feature of constant current when it lights, the driving circuit of ultra high-bright LED is designed, analyzed and optimized by experiment. The results show that ultra high-bright LED can be successfully utilized in LCoS micro-display. |
