A CS-LCOS based projection system with high efficiency and compact size is developed. The light collection system is optimized to obtain about 75% coupling efficiency from LED to LCOS surface. More than 10% of the throughput of the overall system is expected with considering the collection efficiency, color mixing, polarization, surface reflection, and efficiency of each component. Measurement results show around 30 lumen flux output at 8 watts power input including LED and LCOS driving request, which is accordance with the design evaluation. The size of the demo is around 65mm*50mm*17mm, with a total volume of 55CC. Almost 100% NTSC is achieved with the benefit of sequential color generated with RGB LED shining and fast LC response. © 2011 SID. Source

System design of a detachable mobile phone projector based on LCOS projection display has been discussed. An Optical Engine (OE) utilizing Color-Filter LCOS could deliver brightness of 8 Lumen at 2W of LED power. A digital interface in the format of Mobile Industry Processor Interface (MIPI) is used. A prototype will be demonstrated. Source
