Abstract: A micromirror of a micromirror array of a spatial light modulator used in display systems comprises a mirror plate attached to a hinge that is supported by two posts formed on a substrate. Also the mirror plate is operable to rotate along a rotation axis that is parallel to but offset from a diagonal of the mirror plate when viewed from the top. An imaginary line connecting the two posts is not parallel to either diagonal of the mirror plate.

Abstract: Disclosed herein is a micromirror array device package having a light blocking area for reducing unexpected light scattering from the surfaces of the posts.

Abstract: A digital system without a color filter is provided. The desired color components are produced by a light source capable of emitting the desired color components. The color components are delivered to the pixels of the spatial light modulator through a group of optical lens and/or lightpipes, but without a color filter.

Abstract: Disclosed herein is a method of projecting images using light valves. Pixel patterns generated of the light valve pixels based on image data are projected at different locations at a time.

Abstract: Disclosed herein is a micromirror device having a reflective mirror plate with reduced dimensions. The micromirror device can be a member of an array of micromirror devices for use in optical signal modulations, such as display applications and optical signal switching applications.

Abstract: Disclosed herein is a projection system that comprises an illumination system providing incident light, a projection lens for directing the incident light onto one or more spatial light modulator from where the incident light is modulated in accordance with a stream of image data derived from the desired image, and a projection lens for projecting the modulated light onto a screen.

Abstract: 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.

Abstract: Disclosed herein is a micromirror device having in-plane deformable hinge to which a deflectable and reflective mirror plate is attached. The mirror plate rotates to different angles in response to an electrostatic field established between the mirror plate and an addressing electrode associated with the mirror plate.

Abstract: A method and a color rendering filter for compensating for deficiency in illumination light from a light source in display systems are provided. The color rendering filter has a color that is determined based upon the spectrum, sensitivity of viewer's eyes over the visible light range, and a pre-determined waveband threshold.

Abstract: Multiple pixel arrays are enclosed in one single package. The multiple pixel arrays can be disposed in the package with any desired geometric configurations.

Abstract: A method for forming a MEMS device is disclosed, where a final release step is performed just prior to a wafer bonding step to protect the MEMS device from contamination, physical contact, or other deleterious external events. Without additional changes to the MEMS structure between release and wafer bonding and singulation, except for an optional stiction treatment, the MEMS device is best protected and overall process flow is improved. The method is applicable to the production of any MEMS device and is particularly beneficial in the making of fragile micromirrors.

Abstract: A micromirror array comprises micromirrors of different properties for use particularly in display systems. Micromirrors of different properties can be arranged within the micromirror array according to a predetermined pattern, or randomly. However, it is advantageous to arrange the micromirrors with different properties within the micromirror array neither in complete order nor complete in random.

Abstract: Disclosed herein is an illumination system for use in display systems employing spatial light modulators. The illumination system comprises a fastening mechanism for securing the bonding of the walls of the light integrator of the illumination system. A heat dissipation mechanism can be alternatively provided for reducing the temperature of the illumination system by dissipating the heat thereof.

Abstract: Disclosed herein is a method of projecting images using reflective light valves. Pixel patterns generated of the light valve pixels based on image data are projected at different locations at a time such that the perceived resolution of the projected images can be higher than the total number of pixels in the light valve.

Abstract: A method for processing microelectromechanical devices is disclosed herein. The method prevents the diffusion and interaction between sacrificial layers and structure layers of the microelectromechanical devices by providing selected barrier layers between consecutive sacrificial and structure layers.

Abstract: Disclosed herein is a projection system that comprises an enhanced projection mode and regular mode. In the enhanced mode, media contents are displayed such that the perceived resolution is higher than the native resolution of the light valve. In the regular mode, media contents are projected with a resolution of the naïve resolution of the light valve. Viewers can operate the projection system in either of the two modes based upon the property of the media content or the viewers' preferences, or both.
