Liquid crystal on silicon TFT Display Module design

LCoS (Liquid Crystal on Silicon) display design and application technology Category: HMI Published :2007 -08-29 Abstract: LCoS display structure and purpose, given LCoS display chip design methods and their practical design results. LCoS display is a reflective liquid crystal display, and its surrounding drivers and active pixel matrix using CMOS technology on silicon substrate, and a liquid crystal cell as the base wafer, which has a small size and high resolution for display properties. 5.7 TFT display module

1 LCoS display chip - a new class of SoC chip
LCD monitors mentioned, people will think of laptop LCD monitors, or large-screen plasma display. Exciting emerging fabricated on a silicon LCoS is an LCD display technology .
LCoS display is a new type of reflective displays, semiconductor VLSI technology and LCD technology unique combination of high-tech products, and its graphics chip diagonal size of 18mm. As LCoS using conventional CMOS technology can be mass-produced, and with the further development of semiconductor technology miniaturization while increasing resolution, LCoS display will have low power, miniature size, ultra-light weight and other characteristics, so in personal portable display applications aspect is very advantageous, in particular power consumption lower than Many active matrix liquid crystal display (AMLCD), and the production costs are expected cathode ray tube (CRT) to be compared.
Although typically only fingernail size LCoS display, the corresponding pixel also very small, as well as against direct eye to distinguish, but LCoS displays are equipped with a variety of the optical system for enlarging an image (Optical Engine): one is directly projected onto the retina to form an enlarged virtual image, thereby generating a virtual image of the individual flat display technology; other projection screen is to use a real image is formed larger, as shown in Figure 1. LCoS display technology has led to a new type of large-screen flat panel display was born. 16x4 lcd display
LCoS display technology as the core of the key components of the silicon backplane (LCoS display chip), is a multi-function, multi-structure system on chip (SoC), which integrates the entire display system around 18mm wafer. However, SoC chip design category the entire system must be holistic in various situations. Because of this well-designed, with a combination of display by the separation system compared to IC, SoC chip can be in the same class technology conditions to achieve higher performance system metrics. It can be expected, the system design and production of a new generation of chip mode LCD display, which will be very broad application prospects.
