漫谈投影机新技术 LCD和DLP技术大比拼(国外英文资料) Talk about the new technology LCD and DLP technology From the author: anonymous : Yesky. LCD projector: LCD projector is a high-tech product of LCD technology, lighting technology and integrated circuit development. Its key technology is the manufacture of LCD panels. LCD projectors use LCD photoelectric effect, the liquid crystal molecules are arranged under the effect of electric field changes, affect the light transmittance and reflectance of LCD units, which affect its optical properties, and color images with different gray levels. LCD compares with DLP image Now LCD projector highest support resolution can reach 1600 by 1200 (UXGA), use the time could be extended to more than 8 hours, high brightness and high fidelity image color, you can easily access to all kinds of video signal. They are compact, lightweight and easy to carry. The development of the projector entered a new era. Underlying technology of LCD projector, LCD panel have been only Sony and Epson two companies have research and development and production capacity, after years of development, the LCD panel technology mature gradually. LCD technology has been working to improve performance and reduce processing costs. It is primarily in enhancing performance by raising the opening rate to improve the efficiency of light, it also USES the micro lens array technology to improve the light transmittance of LCD panels, reduce the display of the image pixels, and make the image more exquisite. At present, LCD projectors have reached quite high levels in brightness and image sophistication. In addition to high-end cinema products, LCD products retain a bright lead in the brightness of single-chip DLP products in common application products and low-end high-performance projectors. The manufacturers of LCD projectors are mainly Japanese and Korean manufacturers. There are Sony, Epson, NEC, sanyo and mitsubishi. LCD projector has two kinds of LCD panel projector and LCD projecto
