摘要： A beam shaping prism used in an optical pickup, the beam shaping prism includes a first prism having an incident surface and a second prism having an inclined surface. Since a beam entering the beam shaping prism makes right angles with a beam emerging therefrom, it is easy to optically arrange and assemble elements.

摘要： A projection television includes a video processor to process input video signals, a single CRT to project light according to the processed video signals, a color wheel located in a front of the CRT to filter the light projected from the CRT into predetermined colored light, and a controller to control a rotation of the color wheel according to the input video signals. The projection television uses the color wheel to realize colored light by dividing light produced by the single CRT.

摘要： A device for enhancing contrast for a liquid crystal display (LCD) projection system is provided. The contrast enhancing device includes an image driver supplying an image signal, a LCD panel for converting the input image signal into an optical image signal, and a contrast control portion positioned on the same optical axis as that of the LCD panel, for controlling an amount of scanned light according to the brightness of a corresponding image. Accordingly, the projection system adopting an image display device as a liquid crystal device provides a remarkably enhanced contrast enhancement effect. In particular, as the brightness of the total image is brighter, the contrast enhancement effect becomes larger.

摘要： An optical head includes a substrate, a laser diode, a photodetector, an objective lens, a prism, and an optical element. The laser diode is installed on the substrate and emits light. The photodetector is installed on the substrate and receives the light. The objective lens is installed on a first side of the substrate and focuses the light emitted from the laser diode onto a recording surface of a disc. The prism is installed on a second side of the substrate, transmits the light emitted from the laser diode toward the objective lens, and transmits the light reflected from the recording surface toward the photodetector. The optical element adjusts an optical path formed between the substrate and the prism.
