  • Publication number: 20260140298
    Abstract: The present disclosure relates to a light-emitting member improving vertical light-emitting characteristics and a display device including same. According to an embodiment, a light-emitting member includes: one surface on which light-emitting patterns are formed; and the other surface through which light reflected and/or refracted by light-emitting patterns is emitted, in which each of the light-emitting patterns is a concave pattern corresponding to a portion of a cone having a bottom surface and a predetermined depth, the bottom surface of the light-emitting pattern has a fan shape, a cross-section of the light-emitting pattern has a right triangular shape, the cross-section is a surface obtained by cutting the light-emitting pattern perpendicularly to the one surface along a line passing through a center of the bottom surface, and an arc portion of the bottom surface of the light-emitting pattern is disposed to face the one side surface.

  • Publication number: 20260050116
    Abstract: A light guide member includes: an incident surface; a pattern arrangement surface on which a plurality of patterns configured to reflect light incident through the incident surface are formed; and a light emitting surface through which the light reflected from the plurality of patterns is emitted. Each of the patterns is a concave pattern and defined by a plurality of surfaces formed on the pattern arrangement surface, the plurality of surfaces include a first surface that is convex in a direction toward the incident surface and a second surface that faces the first surface and is convex/concave in the direction toward the incident surface, an angle between the pattern arrangement surface and a cross-section obtained by cutting the first surface in a direction perpendicular to the incident surface is an obtuse angle, and an angle between the pattern arrangement surface and a cross-section obtained by cutting the second surface.

  • Publication number: 20250035977
    Abstract: A light guide plate allows light received and guided through one side surface to be reflected and/or refracted by a bottom surface and to be emitted through a top surface. Here, the bottom surface includes a plurality of engraved light emission patterns, the bottom surface includes a plurality of outer inclined surfaces that define the light emission patterns, the plurality of outer inclined surfaces includes a first outer inclined surface, a second outer inclined surface, a third outer inclined surface, and a fourth outer inclined surface. Also, the first and third outer inclined surfaces each protrude in an outward direction and are disposed to face each other, one of the first and third outer inclined surfaces is disposed to face the one side surface, and the second and fourth outer inclined surfaces are disposed to face each other and disposed between the first and third outer inclined surfaces.

  • Patent number: 10459148
    Abstract: A display device including a light source and a light guide plate may be provided. The light guide plate includes: a light guiding part which guides light incident on a side thereof from the light source by total internal reflection; a fine pattern portion which emits the guided light only to an upper portion of the light guiding part; a guard ring portion which protects the fine pattern portion from the intrusion of impurities; and a light emitting member which is disposed on a top surface of the fine pattern portion and a top surface of the guard ring portion. The light guide plate is formed of a transparent material.
