  • Patent number: 11175445
    Abstract: Illuminating sections of a light guide with LEDs leads to unwanted light bleeding to other parts of the light guide. Furthermore typically LEDs are placed at a large distance from the area that couples out light from this LED due to a spike in intensity close to the LED. In order to avoid this spike being visible in the lit area the distance is increased which results in unwanted areal increase of the overall system. The present provides a layout to overcome these challenges.

  • Patent number: 8297794
    Abstract: The method is for directing light in a fluorescent piece. Sequentially placed wedge-shaped pieces form a multiple-piece arrangement. Each piece has a base surface and a sloping top surface so that there is a first pointed end at one end and a short end surface at a second opposite end thereof. The pieces are exposed to light beams that hit fluorescent particles disposed inside the pieces. As a result, the particles emit a fluorescent light that are reflected off the inner surfaces of each piece as long as the light beams do not hit the surface at a perpendicular angle. The light beams are directed to penetrate the short end of each piece to form a continuous illuminated surface.

  • Patent number: 8123390
    Abstract: A backlight assembly includes a plurality of lamps, a receiving container, a diffuser plate and a plurality of holding members. The lamps generate a light. The receiving container receives the lamps. The receiving container includes a bottom portion and a side portion protruded from a side of the bottom portion. The diffuser plate is over the lamps to diffuse the light generated from the lamps. The holding members are engaged with the bottom portion. Each of the holding members has a lamp holding portion that holds one of the lamps. 10 The lamp holding portion has an opening for receiving the lamp. The opening is inclined by a first angle with respect to a normal line of the bottom portion. Therefore, the lamps are securely combined with the lamp holding portion, and the lamps are easily assembled to protect the lamps from an externally provided impact.

  • Patent number: 8083391
    Abstract: A planar light source of the present invention has three lamps along a side face of a rectangular light guide plate. The lamps are arranged along an incidence plane which is one side plane of the light guide plate. The three lamps are arranged so as to be kept apart from each other at a given interval, and two lamps are arranged in close proximity to the incidence plane that is one side plane of the light guide plate. One lamp is arranged away from the incidence plane that is one side plane of the light guide plate with respect to the two lamps. A lamp reflector is formed continuously so as to become close to the three lamps and surround the respective three lamps, and assumes a substantially convex cross-sectional shape.

  • Patent number: 8057066
    Abstract: A backlight assembly and a display apparatus having the backlight assembly are disclosed. A diffusion plate is provided above a plurality of lamps. Diffusion patterns that cause contrast inversion and diffusion patterns that do not cause contrast inversion are arranged on a surface of a diffusion plate, in an alternating manner along a longitudinal direction of the lamps. Thus, a brightness difference between a first area in which the lamps are positioned and a second area between two adjacent lamps is reduced, thereby improving a brightness uniformity of light from the backlight assembly.

  • Patent number: 8059214
    Abstract: Fluorescent tubes are arranged such that their arrangement spaces gradually become wider in central area than in edge areas, fluorescent tubes located in the vicinity of the central area of an arrangement direction are bent into chevron-shapes such that the central parts of the longitudinal directions of the fluorescent tubes become crests which provide access to a diffusion plate, respective two adjacent fluorescent tubes which are straight tubes are connected to one another, thereby constituting pseudo U-shaped tubes, and an AC power is supplied through terminals lined up along one side of a direct-type backlight device. A reflector plate is bent so as to match with the curvature of the bent fluorescent tubes, and is formed with a protrusion which allows the fluorescent tubes located in the vicinity of the central area of the arrangement direction to be raised so as to protrude toward a diffusion plate.

    Abstract: Backlight assembly includes a plurality of light guide plates, a plurality of light modules, and a plurality of driving units separately in control of corresponding light modules which are configured at the incident sides of the LGPs. Each light module faces two adjacent LGPs such that the driving unit drives the light module to provide light for two adjacent LGPs at the same time. As local dimming function is switched, besides the power-saving and the high contrast, the local edge effect due to the joint of the LGPs can be reduced.
