Abstract— Current LCD designs have about 5–7% transmittance in the white state without the use of DBEF3M (double brightness enhancing film) and up to 10–14% with DBEF film. We presented a design which can further increase the brightness by up to 60%. The basics for this design are new Optiva materials which have a high birefringence about 0.3–0.4 and low absorption losses in the visible spectrum. This material can be used to produce multilayer interference reflective polarizer and polarization interference color filters. Initial prototypes of these interference elements will be discussed in the paper.
The way to increase efficiency of modern LCD is to remove the absorbing optical components: color filter and dichroic polarizer. Non-absorbing polarizer together with sub-millisecond fast LC mode working in field-sequential RGB mode are the keys to future LCD.
