A backlight unit and a display device including the backlight unit is disclosed The backlight unit includes a light source protective element located on light sources, a base film located on the light source protective element, and a plurality of optical path control patterns, each of which is located to overlap a corresponding one of the light sources, that are disposed on at least one of both surfaces of the base film and configured to direct traveling paths of at least some of incident light rays, the optical path control patterns including an acrylic-based resin or a polyester-based resin and at least one type of inorganic particles dispersed in the resins, thereby enabling a thickness of the backlight unit to be reduced and image quality to improve.

Backlight unit and display device including the same

A backlight unit and a display device are disclosed. There may be provided a backlight unit and a display device with enhanced light absorption of light of an absorption wavelength band and enhanced color gamut, by including a color conversion layer (or color conversion film) for converting the wavelength band of the light emitted from a light source and a light absorption layer (or light absorption film) for absorbing light of a specific absorption wavelength band, in an area adjacent the light source.

Backlight unit and display device

A backlight unit can include a light emitting unit including a plurality of light emitting devices, a light conversion sheet disposed on the light emitting unit and including a plurality of light conversion patterns overlapping with the plurality of light emitting devices, a phosphor film disposed on the light conversion sheet, and a phosphor layer disposed in a position corresponding to a rim portion of the light conversion sheet.

Embodiments of the present disclosure provide a backlight unit comprising a light emitting unit including a plurality of light emitting devices, a light conversion sheet disposed on the light emitting unit and including a plurality of light conversion patterns overlapping with the plurality of light emitting devices, and a phosphor layer disposed in a rim portion of the light conversion sheet and including a phosphor film disposed on the light conversion sheet. A display device including the backlight unit is also provided.

The disclosure relates to backlight unit and display device including the same. The backlight unit includes an array substrate having a first surface on which a plurality of light emitting devices are disposed, and a second surface on which a plurality of Zener diodes are disposed corresponding to the plurality of light emitting devices, a driver substrate having a third surface contacting the second surface of the array substrate, and a fourth surface on which a plurality of driver integrated circuits are disposed, and a cover bottom accommodating the array substrate and the driver substrate.

Disclosed are a light source module, a backlight unit including the same, and a liquid crystal display device including the same, which prevent image quality and reliability from being degraded. The light source module includes a printed circuit board (PCB), a plurality of light sources mounted on the PCB, an optical member provided on the PCB to surround the plurality of light sources, an antistatic cover supported to the optical member to cover the plurality of light sources, and a ground member grounding the antistatic cover.

Light source module, and backlight unit and liquid crystal display device including the same

A light-emitting diode (LED) chip and a display device having the same are provided. A green LED is regrown on a blue LED to produce blue and green light, and a red phosphor is disposed on the blue or green LED to produce red light. Red light, green light, and blue light are to be produced using a single LED chip. The single LED chip forms three subpixels therein so as to facilitate a transfer process of the LED chip to a display panel. The LED chip is configured based on the blue, green, and blue LEDs so as to facilitate the fabrication and driving of the LED chip.

Light-emitting diode chip and micro display device

Disclosed are a light source module, a backlight unit including the same, and an LCD device including the same, which prevent image quality and reliability from being degraded. The light source module includes a plurality of light sources mounted on a printed circuit board (PCB), an optical member provided on the PCB to surround the plurality of light sources, and a conductive member coupled to the optical member. The conductive member includes a protrusion grounding the conductive member.
