Research On Single LCoS For Field Sequential Coloration

In the information explosion era of science and technology, fast and precise display technology for clear and intuitive ability to disseminate information were widely favored by people. Now display technology is all over in people's lives, which have become an important technology for people to obtain information. At the same time, people are more and more serious with the display technology, as a result, various display technologies have emerged. In the 21st century It is the golden age for large flat-panel displays and micro-display system and development of the golden age of pop.As a new micro-display devices,LCoS(liquid crystal on silicon) is a combination of CMOS integrated circuit technology semiconductor and liquid crystal display technology. Because of the various advantages such as small size, high resolution, high-efficient light utilization and low dissipation, LCoS micro-display systems are widely used in portable display systems and Near-Eye display systems. This paper is based on the application of LCoS display in portable microdisplay projection system, including the research work about the working principle and colorization scheme of the LCoS display device during the earlier period of the project and realizing the SVGA resolution,180Hz fresh rate.256-gray scale tricolor video projection display by the single panel LCoS display which was set up in this project.This paper is based on single-panel tricolor LCoS display system with high saturation and high brightness LED as light source. Compared with the traditional display with EBU tricolor, the projected image with the new display is more bright, more colorful and easier to achieve color gamut extension. In order to make the projected image close to the standard color display, the display time of the three primary color is analyzed by the method of white balance.and implemented in two ways. LCoS is essentially a liquid crystal display technology. This paper focused on the non-linear electro-optic properties of liquid crystal and the methods of gamma correction. Finally a practical gamma correction is developed based on normal scheme.by inserting an LUT gamma correction block in the hardware design program.
