Patent number: 6918682Abstract: An illumination system capable of realizing a color image without a color wheel, and a projection system employing the illumination system. The illumination system includes first, second, and third light emitting devices and first and second hologram devices. The first, second, and third light emitting devices emit light beams having different wavelengths. The first and second hologram devices are disposed in an “X” configuration at an angle with respect to the first, second, and third light emitting devices and transmit or reflect incident light depending on the wavelength of the light. The projection system further includes a display device, and a projection lens unit. The display device processes beams incident in one direction via the first and second hologram devices, according to an input image signal, and forms an image. The projection lens unit enlarges and projects the image formed by the display device on a screen. The illumination system and the projection system can realize a wide color gamut.Type: GrantFiled: October 31, 2002Date of Patent: July 19, 2005Assignee: Samsung Electronics Co., Ltd.Inventors: Sung-ha Kim, Soon-Cheoi Choi, Kirill Sergeevich Sokolov

Patent number: 6834963Abstract: An illumination system which realizes a color image without a color wheel and a projector adopting the illumination system. The illumination system comprises at least one light emitting device which emits a light beam having a predetermined wavelength and a holographic optical element which reduces a cross section of the light beam. The projector includes the illumination system, a display device which forms an image by processing light from the illumination system according to an input image signal, and a projection lens which magnifies and projects the image onto a screen. The light emitting device may be constructed in an array form and the arrays may be arranged inline and adjacent to an optical path changer or distributed around an optical path changer at predetermined angles. The arrays and holographic optical elements may be provided in layers in order to reduce a size of the illumination system.Type: GrantFiled: July 30, 2002Date of Patent: December 28, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Sung-ha Kim, Kirill Sergeevich Sokolov
