摘要： A projection system, a spatial light modulator, and a method for forming a MEMS device is disclosed. The spatial light modulator can have two substrates bonded together with one of the substrates comprising a micromirror array. The two substrates can be bonded at the wafer level after depositing a getter material andlor solid or liquid lubricant on one or both of the wafers. The wafers can be bonded together hermetically if desired, and the pressure between the two substrates can be below atmosphere.

摘要： Methods and apparatus for selectively updating memory cells of a memory cell array are provided. The memory cells of each row of the memory cell array are provided with a plurality of wordlines. Memory cells of the row are activated and updated by separated wordlines. In an application of display systems using memory cell arrays for controlling the pixels of the display system and pulse-width-modulation (PWM) technique for displaying grayscales, the pixels can be modulated by different PWM waveforms. The perceived dynamic-false-contouring artifacts are reduced thereby. In another application, the provision of multiple wordlines enables precise measurements of voltages maintained by memory cells of the memory cell array.

摘要： A projection system is disclosed that has a light source of multiple wavelengths, a spatial light modulator and projection optics for projecting an image to be viewed by a viewer or to be displayed on a target. Also provided are one or more color sequencing devices which filter the light multiple times. Whether a single or plural color sequencing elements are provided, a single light beam passes at least twice through a sequence of light filters. In one embodiment, two color wheels provide the ability to filter the light multiple times. By changing the physical position or phase of one series of filters relative to another, the brightness and color saturation of the image projected through the projection optics can be changed. The changes in brightness and color saturation can be performed manually by mechanically changing the phase (or position) of the color sequencing device(s) relative to the light beam. Such changes can be performed step-wise of gradually through a continuum of brightness vs. color saturation points.

摘要： Methods and apparatus for producing a pulse-width-modulated (PWM) grayscale or color image using a binary spatial light modulator. By staggering and re-quantizing the PWM intervals to a clock of a period based on the frame time divided by number of rows in the display, the system's peak bandwidth requirements are optimized for displays of arbitrary resolution and arbitrary choice of PWM waveform. Additionally, a gating circuit increases the optical efficiency of a spatial light modulator using this PWM method in a field-sequential color system by reducing the duration of the blanking period between color fields.
