Seeking Higher Definitions, Makers Push Technological Limits

摘要

Fixed-pixel projectors are broadly divided into three categories according to the image device they use. In the first category are LCD projectors, which use transmissive LCD panels. These include, for example, three-panel transmissive LCD projectors. In the second category are liquid-crystal-on-silicon (LCOS) reflective projectors. This category is subdivided into three sub-categories. Representing one sub-category are Direct-Drive Image Light Amplifier (D-ILA) projectors developed by Victor Co. of Japan. In the two other sub-categories are Grating Light Valve (GLV) and Silicon X-tal Reflection Display (SXRD) projectors, both developed by Sony Corp. ("X-tal" means crystal). Representing the third main category of fixed-pixel projectors are Digital Light-Processing (DLP) projectors, which use Digital Micromirror Devices (DMDs) developed by Texas Instruments, Inc. (TI) of the United States.
