摘要： A display device includes a display panel, a light guide plate disposed under the display panel, a light source disposed adjacent to one side surface of the light guide plate that generates a first light, a first refractive layer disposed between the light source and the one side surface of the light guide plate that has a refractive index greater than a refractive index of the light guide plate, and a second refractive layer disposed between the display panel and the light guide plate that has a refractive index less than the refractive index of the light guide plate. The first refractive layer includes a convex portion that protrudes into the one side surface of the light guide plate.

摘要： A backlight unit includes a light guide plate that includes a side surface that is an incidence surface that is normal to a first direction, a light source adjacent to the incidence surface, and a light conversion layer disposed on an upper surface of the light guide plate that changes a wavelength of light incident thereto. The light conversion layer includes a first portion and a second portion arranged in the first direction. The first portion is closer to the incidence surface in the first direction than the second portion, and the first portion is thinner than the second portion.

摘要： A display apparatus including a light emitting device layer emitting a first light having a peak wavelength of 500 nm or less, a color control layer disposed on the light emitting device layer, the color control layer including an emitting element converting the first light, a color filter layer disposed on the color control layer, and an absorptive scattering element provided in or on the color control layer. The absorptive scattering element may include a light absorbing portion, in which absorptivity of a green or red light is greater than absorptivity of the first light. Accordingly, reflectance of the display apparatus to an external light may be reduced.

摘要： A display device including a display panel driving unit configured to convert an image signal provided from an external device into a data signal such that an image is displayed on a display panel, and to output a first light control signal and a second light control signal. A backlight unit is configured to provide the display panel with a first color light and a second color light different from the first color light in response to the first light control signal and the second control signal. The display panel driving unit is further configured to determine a pulse width of each of the first light control signal and the second light control signal according to a color characteristic of the image signal.

摘要： A display apparatus includes a display panel configured to display an image. A light guide plate is disposed below the display panel. The light guide plate has a light incident surface. A light source is disposed adjacent to the light incident surface of the light guide plate to generate first light. A light conversion layer is disposed between the light guide plate and the display panel to convert a wavelength band of incident light. An optical filter layer is disposed between the light guide plate and the light conversion layer to selectively transmit or reflect incident light.
