    摘要: An optically addressed, photoconductive spatial light modulator (SLM) operates in a transmissive mode and is capable of modulating a wide spectrum of visible light. There is no pixel structure or native pixel resolution in the SLM. The SLM has no photodiodes and does not rectify. A light projection system (100) in which one or more SLMs (128, 130, 132) are placed includes a write (image definition) UV light path (102) and a read (illumination) visible light path (104) to form a color image projection display. The write UV light propagates from an image display pattern source (120) and either sequentially or continuously writes image patterns on the photoconductive SLMs. The read visible light propagates through the SLM and is modulated by an electro-optical material, the optical properties of which change in response to the image structure carried by the write light. The result is a high efficiency display system that delivers high resolution color images through a projection lens (190) onto a display screen.

    摘要: A spatial light modulator has an array of elements organized into element rows and element columns and an array of electrodes organized into electrode rows and electrode columns to activate the array of elements. The modulator has pixel circuitry organized into circuit rows and circuit columns with the pixel circuitry being electrically coupled to the array of electrodes, such that there is at least one translation of either circuits in a column to electrodes in a row or circuits in a row to electrodes in a column.
