    摘要： A projection optical system and a projection television employing the same are provided. The projection optical system includes a lens module and an electron beam tube optical module. The lens module includes a plastic power lens and a hybrid lens. The hybrid lens includes a spherical, biconvex, glass lens and an aspheric lens layer formed on at least one face of the spherical lens. The electron beam tube optical module includes a C-shaped aberration correction device, a window, and a coolant disposed between the window and the aberration correction device. Accordingly, the projection television can provide high quality pictures. In addition, it is possible to reduce the manufacturing costs of the projection television.

    摘要： A high-brightness projection television is provided which includes a screen having a first lens for refracting an incident beam into a convergent beam, a second lens for refracting the beam refracted by the first lens into a divergent beam, and a protection plate for protecting at least the second lens, wherein an optical emission material is included in at least one of the above elements to convert invisible lights included in the incident beam into visible lights. Alternatively, the projection television may include an optical emission layer having the optical emission material between a light source and an image generator such as a liquid crystal display (LCD). Accordingly, vertical and horizontal angles of view are increased and overall brightness of the image is improved.

    摘要： A screen having a wide viewing angle and a projection television including the screen are provided. The screen includes a Fresnel lens sheet for converting incident light into near-parallel light, a lenticular lens sheet including a horizontal array of vertical cylindrical lenses for horizontally emitting light, in which vertical black stripes are formed in parallel on connection portions for the cylindrical lenses, and a light diffusion film including a vertical array of horizontal cylindrical lenses for vertically emitting light, in which horizontal black stripes are formed in parallel on connection portions for the cylindrical lenses. In particular, the screen has a wide vertical viewing angle and a high contrast ratio, thereby providing a high definition image.

    摘要： A screen having improved contrast, a wide viewing angle, and uniform luminosity and a projection system including the screen are provided. The screen includes a Fresnel lens sheet, a lenticular lens sheet including first cylindrical lenses extending vertically and formed on a surface of the lenticular lens sheet, and a protective sheet including second cylindrical lenses. The second cylindrical lenses extend horizontally and are formed on a surface of the protective sheet. A tinted layer is formed on surfaces of the second cylindrical lenses. The projection system forms on an image on the screen. The image is generated by a display device and magnified and projected by a projection lens unit. Therefore, a viewer can watch the projection system from an angle wider than that provided by conventional projection systems.

    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： Provided is a method of manufacturing a hybrid aspherical lens. The method includes processing a spherical lens, depositing an aspherical lens material layer on the spherical lens, and pressing a compression mold with an aspherical surface onto the aspherical lens material layer to form the hybrid aspherical lens over the spherical lens. Thus, a hybrid aspherical lens without shaping errors can be manufactured using a simple process.
