“…If true green (TG) is utilized, the efficiency will become one-third of the CG ones. Furthermore, the contrast ratio of our CS LCOS is enhanced by carefully attach a birefringent phase compensator in a certain angle to the LCOS panel; then we can have panel CR around 1,000 [10].…”

A color sequential front-lit (CS-FL) LCOS optical design, which brings advantages of wide color gamut, high resolution, and high contrast for wearable applications, is presented. On the basis of our recent color filter front-lit (CF-FL) LCOS experimental result, which delivers 100 nits/mW (i.e., 17,000 nits at 30 mA driving current of a dual-chip LED), we demonstrated a new CS-FL design of 116 nits/mW using RGB LED and converted green phosphor. The color non-uniformity problem caused by separated individual RGB LED chips was solved by a hollow integrator rod and a sheet of diffuser. Furthermore, together with a mixer light guide (MLG) with grating, spatially averaged RGB light can have a much collimated angular intensity and uniform illuminance distribution to PBS light guide (PBSLG). Besides, the color luminance non-uniformity (standard deviation of color difference) of this newly designed CS-FL can reduced 11% compared to that of the original CF-FL.

“…Reducing the LED turn-on duty m is another way to suppress color mixing as it increases the temporal separation of each color field [22]. Figure 3(d) plots the color gamut ratio for 180Hz frame rate and 90% LED duty.…”

Shin-Tson, "Fastresponse liquid crystals for high image quality wearable displays" (2015). Faculty Bibliography 2010s. 6678. Abstract:We demonstrate two ultra-low viscosity liquid crystal mixtures to enable field-sequential-color wearable displays for low temperature operation, while keeping a wide color gamut. Our mixtures offer ~4X faster response time than a commercial material at 20°C and ~8X faster at −20°C. Other major attractive features include: (1) submillisecond response time at room temperature and vivid color even at −20°C without a heating device, (2) high brightness and excellent ambient contrast ratio, and (3) suppressed color breakup with 360Hz frame rate.
