Abstract

A color management system for use with projection displays includes, for example, a separating polarizing beamsplitter, a compensating prism group, an image assimilator, and a combining polarizing beam splitter. In accordance with an exemplary embodiment, the separating polarizing beamsplitter receives a bi-oriented light input and separates it into two output beams, one comprising a first component and the other comprising a second component. The image assimilator receives an output light beam from the separating polarizing beamsplitter, transmits the light output to one or more corresponding microdisplays, receives one or more modified outputs from the microdisplays, and emits an output comprising those modified outputs to a combining polarizing beamsplitter. The compensating prism group receives from the separating polarizing beamsplitter the other output light beam, transmits it to another corresponding microdisplay, receives from the microdisplay a modified light output, and transmits it to the combining polarizing beamsplitter be combined with the light output from the image assimilator. The compensating prism group may be configured to compensate for an optical aberration induced by the light separator.

Description of the invention (l) 1. [Technical field to which the invention belongs] The present invention relates to a color control system for a projection display (pr ojecti ο ndisp 1 ay), and in particular, to a system for controlling lighting The input is a separate color channel to facilitate the overlap of spatial information, and then combine these color channels to facilitate the projection of a full-color image. 0 2. [Previous technology] Regarding projection displays, it is generally desirable to use a color control system, and it is even better that when a relatively high light flux (i numinati0nf 1 ux) is allowed, such a color control system can promote the birth of high-contrast images. . Unfortunately, the existing color control system, in the consistent application of several lighting fluxes, can only use very specific materials to achieve the purpose of increasing comparison, which increases the cost. #The role of the color control system is to first separate the input light (that is, white light) into several color channels of the k-span visible spectrum (that is, red, green, and blue), 1 g, and these separated color channels are illuminated (i 11u m in a te) corresponding to a microdisplay (ie, an LC0s microdisplay), and these color channels are combined to generate output light (ie, white light). Hope He = When the output light projects an image, the spatial information on each color channel is superimposed by the micro display during the recombination (recombinati). As a result, a full-color image is projected using the output light. This is used by institutions

已經證實，先前低成本的顏色調控系統，無法在維持 可靠照明通量的同時，又能夠產生高對比的影像。部分的 原因在於，在色彩分離（color separation)與再結合中， 使用固態立方形（cube-type)的偏振分光器（polarizing beamsplitter)。其他的偏振分光器，例如MacNeille棱鏡 或立方形偏振分光器。”立方形π偏振分光器，本身容易受 到高通量時所引起之熱梯度（thermal gradients)的影 響，發生應力雙折射（stress birefringence)，應力雙折 射會導致光的去偏振（depolarization)與對比的喪失。結 果，對於高對比的影像，就需要使用昂貴高折射率 (high-index)與低雙折射的玻璃。雖然這樣的方法，在低 通量時有效地減少了雙折射，但在高通量時（也就是大於 500流明時），無法有效降低熱所導致的雙折射，而且花費 昂貴。 如圖1所示，習知的顏色調控系統1 〇 〇，一般是 Color 1 ink的Co lor Quad TM，利用四個立方形偏振分光器It has been proven that the previous low-cost color control system was unable to produce a high-contrast image while maintaining a reliable lighting flux. Part of the reason is that in color separation and recombination, solid-state cube-type polarizing beamsplitters are used. Other polarizing beamsplitters, such as MacNeille prisms or cubic polarizing beamsplitters. The cube-shaped π polarization beam splitter is susceptible to thermal gradients caused by high flux, and stress birefringence occurs. Stress birefringence will cause depolarization and contrast of light. As a result, for high-contrast images, expensive high-index and low birefringence glasses are needed. Although this method effectively reduces birefringence at low flux, At the flux (that is, greater than 500 lumens), the birefringence caused by heat cannot be effectively reduced, and it is expensive. As shown in Figure 1, the conventional color control system 1 00 is generally a Color of Color 1 ink. Quad TM with four cube polarized beamsplitters

According to this system, the input cubic polarizing beam splitter receives the input beam 1 2 0 and separates it into three components, a green light component 2 1, a blue light component 122, and a red light component 123. The red light component 123 receives spatial information from the red light sheet 133, the blue light component 122 receives spatial information from the blue light sheet 132, and the green light component 1 will receive space information from the green light sheet 1 3 1. The output cube polarizing beam splitter then combines the red light component 1 2 3, the blue light component 1 2 2 and the green light component 1 21 to form a full-color image 1 4 0.

In order to reduce the negative effects caused by the use of cubic polarizing beam splitters, in the color control system, an attempt was made to use a piate polarizing beam splitter to replace the cubic configuration. However, these methods have resulted in several optical aberrations related to the use of flat polarizing beam splitters, such as astigmatism.

Description of the Invention (ίο) Optical aberration. According to this embodiment, the supplementary prism group 240 includes a * -pair of prism compensators. It is worth noting that these prism compensators are separated by an air gap. The size of the air gap depends on the thickness and orientation of the optical separator 22 0, and is generally between 1 and 4 mm, which is substantially 2.5 mm in this embodiment. Furthermore, the air gap can be used to compensate for one or more optical aberrations. As shown in FIG. 4, according to this embodiment of the present invention, the compensation group 240 may exhibit an oblique orientation. For example, the prism set 240 can be oriented at an angle between -30 degrees and +30 degrees. In this embodiment, the group 240 can be directionally compensated at an angle close to 15 degrees. Furthermore, the compensation stack 240 may include a tilt compensator plate 4 6 9 representing a tilt orientation.
