  • Publication number: 20090190063
    Abstract: A liquid crystal display device includes a liquid crystal display panel and a backlight disposed at a rear surface of the liquid crystal display panel. The backlight includes a light source, a frame housing the light source, a heat dissipating plate disposed inside the frame, and a reflective sheet disposed at a surface of the heat dissipating plate on the liquid crystal display panel side. The heat dissipating plate is formed with a heat dissipating fin protruding to a surface of the frame on the side opposite to the liquid crystal display panel through an opening formed through the frame in a portion corresponding to the upper portion thereof and formed with an opening which is closed with the frame and the reflective sheet in a portion corresponding to the lower portion thereof.

  • Publication number: 20090040417
    Abstract: A liquid crystal display device includes a liquid crystal display panel and a backlight arranged on a back surface of the liquid crystal display panel, the backlight including a plurality of rod-shaped light sources, a frame which supports the rod-shaped light sources, and a heat radiation plate which is arranged on an inner surface of the frame. Through holes are formed in the frame, and heat radiation fins are formed on the heat radiation plate in a state that the heat radiation fins project toward a back surface of the liquid crystal display panel through the through holes formed in the frame. Due to such a constitution, it is possible to provide a liquid crystal display device which can enhance heat radiation efficiency.

  • Publication number: 20070076142
    Abstract: In order to solve the problem that sufficient center brightness is not always obtained in a conventional liquid crystal TV and a liquid crystal monitor, a backlight module of the invention includes a plurality of cold cathode fluorescent lamps (CFL) and a diffusing reflector below, the distance between the respective CFLs is arranged so that a central portion is narrow and an end portion is wide, and the backlight module includes a triangular sectional projection structure on at the diffusing reflector only between the CFLs between which the distance is the widest, in the end portion. According to the invention, enhancement of the center brightness without increasing consumption power, reduction in the number of CFLs, and cost reduction accompanying it are achieved.

  • Publication number: 20070035946
    Abstract: In a liquid crystal TV, there is provided a direct back light for increasing brightness in the vicinity of the center of a screen. Plural fluorescent tubes are used for backlight, and the respective two fluorescent tubes are paired and driven. The arrangement intervals of the respective pairs are made smallest in the vicinity of the center of the screen to increase the brightness in the vicinity of the center of the screen. The use of the paired fluorescent tubes is to alleviate a variation of the brightness in each of the fluorescent tubes.

  • Publication number: 20070008240
    Abstract: The present invention aims at the lowering of an image quality of an outer peripheral portion of an image display region. For this end, in a display device in which a plurality of display panels are arranged from a front side to a depth side in an overlapped manner and an image is displayed on the respective display panels, the respective display panels have regions which allow the image to be displayed thereon (image display regions) broadened toward the depth-side display panel from the front-side display panel.

  • Publication number: 20060268203
    Abstract: The present invention prevents a displayed three-dimensional stereoscopic image from being darkened in a three-dimensional display device of a DFD type. The present invention provides a three-dimensional display device in which at least one of a plurality of display panels is formed of a display panel having pixels each of which includes color filters having the higher transmissivity than color filters (basic color filters) which express colors of an image or transparent windows.

  • Patent number: 6201571
    Abstract: A reduction processing section (10) performs a reduction processing for a picked-up image on frame memory (7). A character image generating section (30) converts contents of parameter table (6) and information concerning date, time and picking-up conditions to a character image and store it in a work memory (31). A synthesis processing section (32) synthesizes the character image on the work memory (31) with the reduced image from the reduction processing section (10). The synthesized simultaneous display reduced image (33) is stored together with an original image (14) and a compressed image (15). Thus, when simultaneous displaying is performed with a application software on a personal computer, an reduced image for use in simultaneous displaying, on which picking-up date, picking-up time and picking-up data are superimposed, is displayed, whereby processing speed for image data retrieval is increased. Moreover, an original image is stored as it is without modifying an initial image.
