  • Publication number: 20140085567
    Abstract: A display device includes a display panel and a backlight unit. The display panel is configured to display an image. The backlight unit is configured to provide light to the display panel. The display panel includes an array substrate including a plurality of pixel areas, an opposite substrate facing the array substrate, a liquid crystal layer disposed between the array substrate and the opposite substrate, and a wavelength-selective transflective member disposed on the array substrate or the opposite substrate.

  • Publication number: 20130235613
    Abstract: In a light guide plate and a display apparatus having the light guide plate, a light guide plate includes reflective prisms, in which at least one of the reflective prisms includes an inclined angle adjustable according to an inclined surface of a defective portion thereof and compensates for a distortion of light caused by the defective portion.

  • Patent number: 8506152
    Abstract: A light guide plate includes at least one incident surface into which light is incident, an exit surface at least one end of which is connected the incident surface and through which the light is output, an opposite surface spaced apart from the exit surface and opposing the exit surface, and a plurality of reflective patterns extending from the exit surface toward the opposite surface. When a direction from the exit surface to the opposite surface is referred to as a first direction, a direction perpendicular to the incident surface is referred to as a second direction, and a direction parallel to the incident surface and perpendicular to the first direction is referred to as a third direction, a length of each reflective pattern in the first direction is smaller than a distance between the exit surface and the opposite surface, and a length of each reflective pattern in the second direction is larger than a length of each reflective pattern in the third direction.

  • Publication number: 20120106196
    Abstract: A light guide plate includes a light incident surface, a light facing surface facing the light incident surface, a connection surface connecting the light incident surface with the light facing surface, and a top surface connected with the light incident surface, the light facing surface, and the connection surface. The light incident surface receives light from a light source, the light facing surface reflects light, and the top surface outputs light toward a display panel. The connection surface includes at least two absorption surfaces parallel to a straight line linking a center of an arc with an end of the light incident surface and at least one reflective surface interposed the two adjacent absorption surfaces to reflect the light.
