摘要： 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.

摘要： 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.

摘要： A spatial light modulator is disclosed, along with a method for making such a modulator that comprises an array of micromirror devices. The center-to-center distance and the gap between adjacent micromirror devices are determined corresponding to the light source being used so as to optimize optical efficiency and performance quality. The micromirror device comprises a hinge support formed on a substrate and a hinge that is held by the hinge support. A mirror plate is connected to the hinge via a contact, and the distance between the mirror plate and the hinge is determined according to desired maximum rotation angle of the mirror plate, the optimum gap and pitch between the adjacent micromirrors.In a method of fabricating such spatial light modulator, one sacrificial layer is deposited on a substrate followed by forming the mirror plates, and another sacrificial layer is deposited on the mirror plates followed by forming the hinge supports. The two sacrificial layers are removed via the small gap between adjacent mirror devices with spontaneous vapor phase chemical etchant. Also disclosed is a projection system that comprises such a spatial light modulator, as well as a light source, condensing optics, wherein light from the light source is focused onto the array of micromirrors, projection optics for projecting light selectively reflected from the array of micromirrors onto a target, and a controller for selectively actuating the micromirrors in the array.

摘要： A spatial light modulator is disclosed, along with methods for making such a modulator. The spatial light modulator comprises an array of micromirrors each of which comprises a deflectable and reflective mirror plate. For enabling the deflection of the mirror plate, incisions are made within the area of the mirror plate with each incision being fully enclosed within the area of the mirror plate. The incisions collectively define a deformable hinge that is on the same plane as the mirror plate at the non-deflected state.

摘要： Disclosed herein is a micromirror array device that comprises an array of reflective deflectable mirror plates each being associated with one single addressing electrode to be deflected to an ON state angle. A light transmissive electrode is disposed proximate to the mirror plates for deflecting the mirror plates to a non-zero OFF angle. The mirror plates are arranged in the array with a center-to-centre distance of 10.17 microns or less.
