Projection televisions or video projectors are image projection systems that generate images by using image generation means, such as small-sized cathode ray tubes (CRT), liquid crystal displays (LCD), and polymer dispersion liquid crystals (PDLC) as image sources. The image projection system can be divided into two types according to an image projecting method. One is a front projection system in which an image is directly projected on the front surface of a screen, and the other is a rear projection system in which an image is projected on the rear surface of a screen. Projection television sets are a popular alternative to picture tube television sets, as they provide relatively large viewable screens that cannot be efficiently produced using conventional picture tubes. The image projection systems magnify and project the images onto a large screen to display desired images. Due to the advantages of providing large-sized images, the demand for projection televisions and video projectors has been increasing. In the rear projection television, a projector disposed within a cabinet projects projection light onto a light transmission screen panel disposed at the front of the cabinet, from behind, to thereby display an image on the screen panel. The brightness of a display image of the rear projection system is much higher than that of the front projection system. Projection televisions typically include an enclosure with an optical unit, a reflecting mirror reflecting the projected beams, and electronic components for receiving and projecting an image onto a screen assembly mounted on the front of the enclosure. Rear projection screens transmit an image projected onto the rear of the screen to an audience space. Rear projection screens typically include a system to diffuse light transmitted into the audience space. A projection screen receives images from projectors on a first side and displays the images on a second side with controlled light dispersion of all the displayed images.
