摘要： In a LCD (Liquid Crystal Display), uniformity correction of black and white is employed to improve picture quality and contrast. Extending the drive range and allocating a few gray scale levels to this extended range can accomplish the correction without penalty to contrast. Such an arrangement can be particularly helpful for projection display systems such as those based on LCOS (liquid crystal on silicon).

摘要： Backlighting is provided for a display panel display by directing light from a source (10) via rotating means (16, 30) to plurality of optical wave guides (24) which are positioned with one end (24') towards said means and the other end (24") attached along one edge (26') of the panel (26) to which backlighting is provided. The beam is rotated providing light sequentially to each of the wave guides (24) with resulting scrolling of the light across the panel (26) behind the display panel array.

摘要： An image projection system includes a liquid crystal on silicon (LCOS) panel (504), a projection lens assembly (505), and a wire-grid PBS (503) disposed to direct at least a portion of source light towards the LCOS panel (504), and to direct a portion of light reflected from the LCOS panel (504) to the projection lens assembly (504). In addition, a field léns (506) and a quarter-wave retarder (507) are optically interposed between the LCOS panel (504) and the wire-grid PBS (503). The insertion of the quarter wave retarder (507) between the LCOS panel (504) and wire-grid PBS (503) helps improve contrast by correcting polarization aberrations otherwise caused by the nontelecentricity of the field lens (506).

摘要： A prism is mounted onto a motor without regard to its rotation angle relative to the motor index. Its position is electronically set later after construction of the optical path. A motor controller is used to control the rotation of the prism. This motor controller keeps the prism spinning at a constant velocity and positions the prism phase (rotation angle versus time). A variable offset is used to position the absolute prism rotation as a function of time. The phase may be advanced or delayed by an operator during set up. Each prism has its own phase. The phase of each prism in the system is set so that the illumination pattern correctly matches the video addressing of the panel. This is a one time set up during construction. The correct positions are set, and stored in non-volatile memory for life.
摘要翻译：棱镜安装在马达上，而不考虑其相对于马达索引的旋转角度。它的位置在光路构建后稍后进行电子设置。电机控制器用于控制棱镜的旋转。该电机控制器保持棱镜以恒定的速度旋转并定位棱镜相位（旋转角度对时间）。使用可变偏移量将绝对棱镜旋转定位为时间的函数。在设置期间，操作者可以提前或延迟该阶段。每个棱镜都有自己的相位。系统中的每个棱镜的相位被设置为使得照明图案正确地匹配面板的视频寻址。这是施工期间的一次设置。设置正确的位置，并将其存储在非易失性存储器中。

摘要： Compensation of lateral-color chromatic-aberration effects in a digital color-graphics projection display (400) is achieved by providing projection optics (452, 652) for the projection display (400) which is nontelecentric to a certain degree to establish an angled geometry for gathering light off axis for projection by the projection optics (452, 652) and by providing a plurality of component-primary-color object planes for object digital graphics of different primary colors to be projectively displayed through the projection optics (452). At least two of the component-primary- color object planes (690, R, G, B) are located at different effective axial distances from the projection optics (452, 652) are respectively keyed to the angled nature of the off-axis light gathering of the projection optics (452, 652) and to the lateral-color chromatic-aberration differences in lateral magnification by the projection optics (452, 652) at different primary colors so that such color-dependent differences in lateral mangnification tendto be compensated.

摘要： A digital image projector (500; 400) includes an illumination-light source lamp (504; 404) and illumination beam forming optics (506, 510, 526; 406, 410, 426, 466) for forming a white-spectrum illumination beam (509; 409) and color-band-separation optics (530, 530'; 436) to divide the illumination beam (509; 409) into color-component subbeams (542R, 542G, 542B). The digital image projector (500; 400) also includes a reflective digital-image-encoding polarization modulator mechanism (580; 440R, 440G, 440B) such as a reflective liquid crystal display polarization modulator to reflectively modulate linearly polarized subbeams to form color-component image encoded-polarization subbeams and projection lens optics (590; 490) for projecting a color image divided from the image encoded-polarization subbeams. The digital image projector (500; 400) further includes a plate-supported, surface mounted fixed polarization-axis polarizing beamsplitter (570; 470) such as a wire-grid polarizing beamsplitter for dividing the color image from the image-encoded-polarization subbeams in which a polarizer support plate (572; 472) of the polarizing beamsplitter (570; 470) faces an illumination-source side of the optical system of the projector (500; 400).
