Patent number: 7465053Abstract: A lens array wheel 4 receives light irradiated in a direction parallel to its rotation axis, to cyclically deflect the light. On each of liquid crystal display panels 7R, 7G, and 7B, the light is circularly scrolled, the effect of substantial intermittent illumination is produced, and hold blurring is reduced. A panel driver 15 starts to feed a pixel-driving signal in the succeeding frame to a pixel existing at a position, through which an illuminating area passes, on each of the liquid crystal display panels 7R, 7G, and 7B.Type: GrantFiled: March 26, 2003Date of Patent: December 16, 2008Assignee: Sanyo Electric Co., Ltd.Inventors: Mineki Taoka, Haruhiko Murata, Toshiya Iinuma, Koji Ishii, Kazuki Hashizumi, Kazuhiro Arai, Hideyuki Kanayama, Takashi Ikeda, Shouichi Yoshii, Yoshihiro Yokote, Yasuo Funazou

Patent number: 7407293Abstract: An ion wind generator is arranged in the vicinity of a light source. The ion wind generator allows an air flow by negatively ionizing air by corona discharges using negative side needle electrodes, and drawing the negatively-ionized air using a ground side mesh electrode. High-temperature air surrounding the light source is drawn by the air flow and exhausted from an exhaust port at a rear side of a casing. An ozone decomposition catalyst filter is provided in the exhaust port. Ozone (O3) is generated by the corona discharges in the ion wind generator. However, the ozone is decomposed by passing through the ozone decomposition catalyst filter provided at the exhaust port.Type: GrantFiled: December 11, 2003Date of Patent: August 5, 2008Assignee: Sanyo Electric Co., Ltd.Inventors: Koji Ishii, Takashi Ikeda, Hideyuki Kanayama, Yasuo Funazou, Takashi Miwa

Patent number: 7270425Abstract: An optimal processing portion (21) inputs a video signal (RGB signals) and analyzes 1-frame video in the video signal. For example, if the intensity of red color is 0 percent in all dots in 1-frame video, the optimal processing portion (21) applies to a light source gain adjustment portion (22) a control signal for rendering a gain of the illuminating device (1R) 0 percent (minimum amount of light). The light source gain adjustment portion (22) receives the control signal and controls power supply to the illuminating device (1R). In addition, the optimal processing portion (21) applies a driving instruction for rendering the amount of light transmission 0 percent with regard to all dots of the liquid crystal display panel (3R), for example, to a LCD signal processing portion (23).Type: GrantFiled: December 25, 2003Date of Patent: September 18, 2007Assignee: Sanyo Electric Co., Ltd.Inventors: Kazuhiro Arai, Yasuo Funazou

Patent number: 7210790Abstract: An ion wind generator (20) is arranged on one side of a light source (1). The ion wind generator (20) produces an air current by negatively ionizing air by corona discharges at a needle electrode (21), or negative side, and drawing the negatively-ionized air at a cylindrical electrode (22), or positive side. The air current blows toward the light source (1) and removes heat generated by the light source (1). An ultraviolet ray from the light source (1) is introduced to a vent of the ion wind generator (20) by a first dichroic mirror (4) and a ultraviolet ray reflection mirror (17). Though air exhausted from the vent includes ozone (o3) produced by corona discharges, the ozone is decomposed by the ultraviolet ray.Type: GrantFiled: March 26, 2003Date of Patent: May 1, 2007Assignee: Sanyo Electric Co., Ltd.Inventors: Koji Ishii, Takashi Ikeda, Hideyuki Kanayama, Yasuo Funazou, Shunichi Kishimoto, Yoshihiro Yokote, Takashi Miwa

Patent number: 7204605Abstract: The auxiliary light source has LED chips respectively emitting red lights arranged therein in an array shape, and has lens cells for parallelizing light arranged therein on the light exit side of the LED chips, for example. The LED chip is arranged in correspondence with each of lenses composing a pair of fly's eye lenses, and the pair of lenses introduces the light emitted from the LED chip into the whole surfaces of liquid crystal panels. A mixing mirror transmits white light emitted from a main light source and reflects light emitted from the auxiliary light source, and mixes the white light and the auxiliary light respectively emitted from both the light sources and introduces the mixed lights into the pair of fly's eye lenses.Type: GrantFiled: January 21, 2004Date of Patent: April 17, 2007Assignee: Sanyo Electric Co., Ltd.Inventors: Hideyuki Kanayama, Takashi Ikeda, Yasuo Funazou, Yoshitaka Kurosaka, Yoshihiro Yokote

Publication number: 20060132725Abstract: An illuminating device (1) is formed of a light source (12) in which LED chips (11) are arranged in an array shape and lens cells (14) are arranged on a light-emission side of each of the LED chips (11), and a pair of fly's eye lenses (13) that integrates and guides to a liquid crystal panel (3) the light emitted from each of the LED chips (11) and collimated by the lens cells (14). The LED chip (11) and the lens cell (14) are formed in a square shape, and an aspect ratio thereof corresponds to that of the liquid crystal display panel (3). In addition, the lens cells (14) are arranged separately from one another in such a manner to have wall surfaces (air gaps), and the wall surfaces serve as reflective surfaces.Type: ApplicationFiled: December 25, 2003Publication date: June 22, 2006Inventors: Fusao Terada, Kenji Torazawa, Yasuo Funazou, Yoichi Tsuchiya, Katsutoshi Hibino, Hideyuki Kanayama, Shouichi Yoshii, Yoshitaka Kurosaka
