日本是当前FPD(平板显示器)产业发展最快的国家,原来从事CRT显示器件和CRT电视行业的公司,几乎全部投入到FPD产业上来,如松下、日立、先锋的PDP,夏普为首的LCD,以及JVC公司的D-ILA投影,三洋电机LCD投影,东芝佳能的SED,东北先锋的有机EL,三菱的DLP投影等等。日本显示器件厂商争相推出的五花八门的平板电视正在全球推广和普及,呈现出群雄逐鹿、八仙过海的竞争局面。 相似文献

A period of rapid growth and change in the display industry has recently given rise to many new display technologies. One such technology, the Digital Micromirror DeviceTM (DMD), developed at Texas Instruments, represents a unique application of microelectromechanical systems to the area of projection displays. In this paper, we describe a representative example of a DMD-based projection display engine, the digital display engine (DDE). The DDE is based on a single-DMD device having array dimensions of 800×600 elements, illuminated by a metal halide arc lamp through a compact optics train. The engine is designed for portable and fixed conference-room graphics and video display applications, and many design decisions were made to tailor the engine for its intended venue. The design of the projection engine optics and electronics is discussed, along with the basic operation, manufacture, and reliability of the DMD itself 相似文献

The Korean display industry, led by the Samsung and LG Group, has been investing more than 3 billion US dollars in the development and production of large bright high-definition liquid-crystal displays (LCDs) and plasma display panels (PDPs) using new fifth-generation substrate glass. Recent developments have been significant and wide-ranging, with brighter and longer life characteristics as well as improving the manufacturing process for lowered production cost. Samsung Electronics has developed the world's largest 40-in ultra-extended graphics adapter (UXGA) thin-film transistor (TFT) LCD panel for high-definition televisions and engineering workstations, while LG Electronics manufactured a brighter high-definitional 65-in wide UXGA PDPs competing with projection televisions for home theater. Since the first-stage National Research Project for developing TFT LCDs and PDPs was terminated in September 2001, the second-stage Advanced New Research Program for developing more wearable and reliable organic light-emitting diodes than conventional types are proposed by a group of research scientists and engineers working for novel display materials in academia and government-funded research institutes as well as display industries in 2002 相似文献
