    摘要: In an image display system capable of displaying an M x N number of pixels based on optical projection, a light source (100) emits a white light, the white light being reflected on a total mirror (106) at a predetermined angle. An optical filter (108, 110) splits the white light reflected from the total mirror (106) into a trinity of primary light beams, i.e., a red, green and blue light beam. Each of a trinity of arrays of M x N actuated mirrors (118, 120, 122) generates an optical pixel signal by reflecting the primary light beams impinging thereon, each of the actuated mirrors in the arrays (118, 120, 122) being capable of changing the optical path of the primary light beams reflected therefrom, wherein a driver circuit (130) controls each actuated mirror based on an input image signal. A projection stopper (124) partially transmits the optical pixel signal and a projection screen (128) displays the optical pixel signals passing through the projection stopper (124).

    摘要: A bistable deformable mirror device (DMD) pixel architecture is disclosed, wherein the torsion hinges are placed in a layer different from the torsion beam layer. This results in pixels which can be scaled to smaller dimensions while at the same time maintaining a large fractional active area, an important consideration for spatial light modulation and for bright, high-density displays such as are used in high-definition television applications.

    摘要: A projection type liquid crystal display device for transmitting three color light beams of RGB through three TN type liquid crystal panels (10, 81) and project­ing the transmitted light beams optimizes the RGB trans­mission characteristics by changing the crossing angles (α) of the polarization axes of a polarizer (79) and an analyzer (80) with respect to the orientation directions of the respective RGB TN cells in specified directions, and also a projection type liquid crystal display device for transmitting a light beam through a TN type liquid crystal panel (41, 51) and projecting the transmitted light beam effects temperature-compensation of the transmission characteristics of the liquid crystal panels (41, 51) by controlling the crossing angle (ϑ) of the polarization axes of a polarizer (42, 52) and an analyzer (43, 53). Both projection type liquid crystal display devices are relatively simple in the construction, are able to optimize the transmission characteristics of the liquid crystal panels (10, 81, 41, 51), and have excellent properties in the contrast and in the color reproducibi­lity.
