The present invention relates to an optical system for a liquid crystal light valve. [Prior art] Full color liquid crystal light valve (LCLV) display systems usually use three separate monochrome LCLVs that can be driven to produce red, green, and blue images. A representative configuration is shown in Figure 丨. The LCLV is usually mounted on a color combination cube and uses a single lens to project a combination image. -Some LCLV configurations cannot use this configuration, so improved methods and devices are needed.

Referring to FIG. 3 ', a display system includes a substrate 302 on which liquid crystal pixel arrays 304, 306, and 308 associated with a red, a blue, and a green image are respectively defined. The configuration of these sub-panels can be changed, and the configuration described is only an example. An illumination source 316 is configured to guide an illumination beam to a red reflector 314, a blue reflector 312, and an illumination source configured to guide the red, monitor, and green portions of the illumination beam to the relevant pixel array. A mirror surface 3 丨 〇. This group a can be called a dichroic trapezoid. A first unitary combination includes units 318, 320 'and a second unitary combination includes units 322, 324. The first and second frames are configured to guide individual optical axes 340, 342 away from an optical axis 344 associated with the pixel array 306. The projection lenses 330, 332, and 334 provided for each color are configured to project images onto a common plane. To avoid image distortion, such as Keystone distortion, the axes 351, 352 of these lenses 330, 3, 34 are shifted inwardly with respect to the axes 34, 342 used for convergence. The chirps 318, 320, 322, and 324 can be right-angled chirps or other chirps: for total internal reflection, or mirrors, such as metal or dielectric lenses, which can be configured to provide corresponding reflective surfaces. As shown in FIG. 3, the lenses 3 3 0, 3 3 2, 3 3 4 and the associated pixel array are at a common optical distance, and the same magnification is generated for each of the pixel arrays. For convenience, the polarized components are not shown in Figure 3. The adjustment of the display system in FIG. 3 can be performed as described below. For focusing, the projection lens and / or the 稜鏡 / LCLV combination may be moved along one or more axes 340, 342, 344 (ie, from left to right in FIG. 3). The image convergence can be adjusted by moving the projection lenses laterally (vertical in Figure 3), and the alignment / entry of the pixel array O: \ 87 \ 87228.DOC -9- 200426427 can be adjusted by the LCLV. This is achieved by the lateral movement of one or more of these combinations. Referring to FIG. 4 ′, a projection system is configured to project and converge images of three pixel arrays 402, 404, and 406 formed on a substrate 409. The optical spacers 420 and 422 are placed between the pixel arrays 402, 404, and 406 and the individual steering 稜鏡 408 and 410, and a cross polarizer 412 is configured to combine the pixel arrays 402. , 404, 406 of these images. An image field lens 417 is placed between the array 404 and the combiner 412, and is usually displaced away from the array 404. A projection lens 414 is disposed along an axis 418 and forms a combined image. To enhance the mechanical integrity, the puppets 408, 410 may be bonded to the combiner 412. In the example of FIG. 4, according to the measurement, the pixel array 40 2, 4 06 is optically far from the lens 414 along the axis 418 (and along the corresponding portion of the fold), and thus the lens 414 is the arrays 402, 406 And the array 404 provides a different magnification. The image size of the array can be electronically controlled or the image area can be adjusted according to the magnification so that the enlarged images match. The image field lens 4-7 is a virtual image of the array 404 selected and configured to form an optical distance that is substantially the same as the optical distance of the lens 414 from the array 402, 406. As shown in FIG. 4, the image field lens 417 has a positive focal length. Therefore, the lens 414 can produce focused, converged images of the arrays 402, 404, 406. Because the optical paths associated with the array 404 and the arrays 402, 406 are different, the images of these arrays show different magnifications, and the size of the arrays can be selected to compensate for the difference in magnification. Generally, the array 404 is configured smaller than the arrays 402, 406 because the magnification associated with the array 404 is greater than the magnifications associated with the arrays 402, 406. O: \ 87 \ 87228.DOC -10- 200426427 The adjustment of this optical system can be implemented as follows. Focus is obtained by adjusting along this axis 418. The convergence is fixed by the nominal fixed positions of the combiner 412, the arrays 402, 404, 406, and the puppets 408, 410. The pixel array driver 1§ can be configured to adjust the image position on the arrays 402, 404, 406, and a part of the arrays can be reserved for the adjustment, which is usually not used for other purposes. FIG. 5 illustrates an alternative configuration shown in FIG. 4. In FIG. 5, an image field lens 502 is disposed facing a surface 504 of a substrate and spaced from a combiner. Referring to FIG. 6, a display system includes a display panel 600 including pixel arrays 601 to 603. An optical spacer 604 is placed on a surface 606 of the display panel 600. Diverters 608, 610 are configured to direct light beams from the arrays 601, 603 to a combiner 612. Instead of a turning chirp or mirror, a light beam is directed from the array 602 to the combiner 612. Image beam lenses 62 and 622 are provided for the light beams from the arrays 601 and 603, respectively. These optical components can be fixed by glue or using a glass support plate or other support structure. The combined light beams are directed to a lens 614 that generates an image based on the pixel array images. Since the pixel arrays 601 and 603 are relatively far away from the lens 614 along a lens axis with respect to the pixel array 602, the image field lenses 620 and 622 are selected to generate virtual images of the arrays 601 and 603, which are close to The array 602 is the same distance from the lens 614. As shown in FIG. 6, the lenses 620 and 622 are plano-concave lenses having a negative focal length. The lens 614 produces a higher magnification for the array 602 than the arrays 601, 603, and a display driver can be configured to electronically adjust the image size of the array to overlap the projected images. Adjust image convergence by moving the image position in the array. The O: \ 87 \ 87228.DOC -11-200426427 does not need to implement the optical system and the arrays are usually fixed together for additional alignment. The display-display system is similar to that shown in FIG. 6 and includes image field lenses 72 (), 722 related to two external pixel arrays, and an image field lens 721 related to the central pixel array. The lenses 72 ° shown are negative focus lenses and the 忒 lens 721 is a positive focal length, plano-convex lens. The image field lens is selected so that the optical path length from the projection lens to the image material is substantially the same. The projection lens can generate different magnifications for different pixel arrays, and such differences in magnification can be compensated according to the image size of the pixel array, or by providing pixel arrays of different sizes. Fig. 8 shows a similar display system in which an image field lens disposed close to the central pixel array rib is closer to the central pixel array. Figure 8 illustrates a configuration similar to Figure 7, in which a dichroic trapezoidal 802 series is configured to illuminate three sub-panels, and a central sub-panel is associated with a converging field lens 804. According to Figure 9, the display system Including pixel arrays 901 to 903, the images produced are combined by a color combination dichroic color 稜鏡 912 and guided to a projection lens 914. Rectangular 稜鏡 904, 906 are placed in the optical paths respectively associated with the arrays 901, 903 And turn 908, 910 to guide the light beam from the arrays 901 to 903 to a color combination 912.
