摘要： In a liquid crystal light valve projector, a quarter-wave compensator plate is disposed between a polarization plate and a liquid crystal light valve to compensate for polarization irregularities induced by the off-incident reflections in the cone of light projected onto the LCLV. The quarter-wave compensation plate reverses the phase of the P component of said illumination light with respect to said compensator plate by 180.degree. thereby eliminating P-polarization leakage during the dark state of an LCLV projector. The invention also combines the compensator plate with a heat shield and a low stress-optical coefficient counter electrode substrate to reduce the birefringence of the LCLV thereby also minimizing leakage of P-polarized light onto the projection screen during the dark state of the projector.

摘要： A reflective liquid crystal light valve includes transparent conductive layers of indium tin oxide (30) employed as an electrode to electrically modulate orientation of molecules of a liquid crystal material that receives a high intensity reading light (40) applied through the transparent electrode. Unwanted double reflection (64,66) from interfaces between the indium tin oxide electrode (30) and adjacent layers (22,32) are minimized by application of broad band anti-reflective coatings (70,72,74,76) formed by one or more pairs of thin layers having alternately high and low indices of refraction.

摘要： A liquid crystal light valve projection system is provided with increased optical overshoot, and thereby decreased optical response time, by employing a liquid crystal mixture (52) having molecules substantially perpendicularly aligned to the face of the liquid crystal light valve electrodes (42,70) and axially twisted. The axial twist of the liquid crystal molecules is provided by laying down alignment grooves (90,92,96,98) for the liquid crystal mixture that are oriented with respect to one another, on the opposite alignment layers, by an angle of between about 45.degree. and 90.degree.. This mutually angled orientation of the opposed alignment grooves on the opposed alignment layers causes optical overshoot of the system to vary when the entire liquid crystal cell (34) is rotated relative to the output polarizer (18) about an axis perpendicular to the output face of the cell. This rotation of the cell (34) of twisted perpendicular liquid crystal relative to the output polarizer (18) allows a faster optical rise time to be achieved.
摘要翻译：通过采用具有与液晶光阀电极（42,70）的表面基本垂直排列的分子的液晶混合物（52），使液晶光阀投影系统具有增加的光学过冲，从而降低了光响应时间，并轴向扭转。液晶分子的轴向扭转是通过将相对于彼此定向的液晶混合物的对准凹槽（90,92,96,98）放置在相对的取向层上，以约为 45°和90°。当相对的对准层上的相对的对准沟槽的相互倾斜的取向导致当整个液晶单元（34）相对于输出偏振器（18）围绕垂直于输出面的轴线旋转时系统的光学过冲变化细胞。扭转的垂直液晶单元（34）相对于输出偏振器（18）的旋转允许实现更快的光学上升时间。

摘要： A process for implementing shading corrections in a video projector. The process selects a color to be shaded, and then sets a projector video level at a selected high video level. A target brightness map is then generated for each of a plurality of preselected shading correction application points at the selected high video level. The process sets the projector video level at a selected low video level, and generates a target brightness map for each of the plurality of shading correction application points at the low video level. Actual light levels are then measured at both the high and low video levels for each shading correction application point, and differences between the target and measured brightness values are minimized. The shading process of the present invention is automatically preformed during projector set-up, and thereby eliminates the inherent subjective and time consuming need for conventional manual shading processes.

摘要： A liquid crystal light valve that has an indium tin oxide (ITO) primary electrode disposed between two silicon dioxide bonding layers. The first bonding layer for bonding the primary electrode to a glass substrate and the second bonding layer for bonding said primary electrode to a hydrogenated amorphous silicon layer. The ITO primary electrode is sputtered which significantly reduces processing time and the silicon dioxide bonding layers allow the primary electrode to be bonded to the glass substrate and the hydrogenated amorphous silicon layer without peeling. For some applications the silicon dioxide bonding layer between the glass substrate and the primary electrode is not necessary.
