A tiled display device includes: a plurality of display devices; and a thermally variable member between the plurality of display devices. The thermally variable member includes a material whose light transmittance is different depending on a temperature.

Tiled display device

A display device includes a display panel including a first area, a second area, and a bending area disposed between the first area and the second area, the bending area having a curvature radius, a data driver disposed on the display panel and overlapping the second area in a plan view, and a bending protection layer disposed on the display panel and the data driver and overlapping the first area in a plan view, the bending area, and the second area. The bending protection layer includes a thermochromic pigment having a light transmittance that varies according to a temperature.

Display device using thermochromic pigment and method for manufacturing the same

A backlight unit and a display device including the backlight unit are provided. A backlight unit includes a substrate, light sources disposed on one surface of the substrate, a first reflective film disposed on one surface of the substrate and including first openings, each of the first openings of the first reflective film exposing each of the light sources, and wavelength filter layers disposed above the first reflective film and disposed to correspond to the first openings, the wavelength filter layers are spaced apart from each other, and each of the wavelength filter layers covers at least one of the first openings.

Backlight unit and display device including the same

A backlight unit includes a light source array including at least one light source which emits light and a circuit board on which the light source is disposed, and a first optical layer disposed on the light source array. The first optical layer includes a first layer which defines at least one concave portion in a bottom of the first layer, where the at least one concave portion is coupled to the light source, a second layer disposed on the first layer, the second layer guiding light incident from the first layer in one direction, a plurality of optical patterns disposed on one surface of the second layer, the plurality of optical patterns selectively emitting light passing through the one surface, and a reflective layer disposed on the bottom of the first layer.

Backlight unit and display device having the same

A backlight unit includes a light source that emits light and a light guide plate disposed adjacent to the light source. The light guide plate includes an incident surface to which light is incident, an exit surface from which light incident through the incident surface exits, a reflection surface facing the exit surface to reflect the incident light, and a plurality of lenticular protrusions disposed on the exit surface. The reflection surface includes an inclined surface proximal to the incident surface and inclined with respect to the exit surface.

Backlight unit and display apparatus having the same

A display apparatus includes a backlight assembly which provides a light and a display panel which receives the light provided from the backlight assembly to display an image. The backlight assembly includes a light source which generates the light, and a light guide plate. The light guide plate receives the light generated from the light source through an incident surface thereof as an incident light, and outputs the incident light through an exit surface thereof as an exit light. The light guide plate includes a first optical pattern and a second optical pattern. The first optical pattern is disposed corresponding to a first area of the exit surface and collects the incident light. The second optical pattern is disposed corresponding to a remaining second area of the exit surface excluding the first area, and collects the exit light.

Display apparatus

An optical structure includes a body facing a light emitting surface of a light emitting diode package and including a portion protruding toward the light emitting surface of the light emitting diode package, where a surface of the protruding portion faces the light emitting surface and forms a reflective surface of the optical structure; and a leg elongated from a periphery of the body toward the point light source, where the leg supports the body to be spaced apart from the light emitting diode package.
