摘要： A rear projector that can be made slim and compact and can prevent image reversal. The rear projector includes a cathode ray tube to scan light and generate an image, a projection lens unit to magnify and project the image generated by the cathode ray tube, a screen on which the projected image is formed, and a reflection optical system interposed between the projection lens unit and the screen to change a path of projected light. The cathode ray tube and the reflection optical system are arranged such that a raster direction of the cathode ray tube and a direction along which the image is formed on the screen are parallel or substantially parallel to each other.

摘要： A projection TV is provided comprising a reflective mirror including an ultra-thin glass substrate having enhanced strength, a reflective layer formed on a surface of the glass substrate to reflect an image, and a protective layer applied to an upper surface of the reflective layer to prevent the reflective layer from being damaged. The reflective mirror minimizes the occurrences of a double image, and a focus characteristic and contrast are enhanced, thereby improving the image quality. In addition, it is possible to make the product lightweight and thus, reduce transportation charges and other manufacturing costs.

摘要： Provided is an image display screen having wide horizontal and vertical viewing angles and a projection television including the same. The image display screen includes a Fresnel screen, a first lenticular screen that widens a horizontal viewing angle and a second lenticular screen including a first portion that widens a vertical viewing angle and a second portion that prevents degradation of contrast due to external light, and a protective screen. The second lenticular screen and the protective screen can be replaced by an integrated screen or a composite screen having the characteristics of both. In addition, a pattern may be formed on the rear surface of the Fresnel screen to perform the same function as the first portion.

摘要： A projection display apparatus with red (R), green (G), and blue (B) monochromatic cathode ray tubes (CRTs) and three projection lenses, disposed in front of the R, G, and B monochromatic CRTs respectively, along with a screen having a predetermined curvature concave in a view direction to control a view distance and focus the light rays projected from the respective projection lenses. The screen includes a Fresnel screen converting the light rays incident from the projection lenses to have predetermined optical directional characteristics in an optical axis direction, and a Lenticular screen, disposed in front of the Fresnel screen and having a curvature corresponding to the Fresnel screen, for forming images from the light rays passing through the Fresnel screen, controlling a view angle, and enhancing an entire screen luminance. The view distance is determined based on a focal length and a curvature radius of the Fresnel screen.
