A backlight unit is provided which includes: a bottom chassis; a light source on the bottom chassis; an optical sheet over the light source; and a support between the bottom chassis and the optical sheet, and configured to support the optical sheet. The support includes: a fastening portion fastened to the bottom chassis, a support portion contacting the optical sheet, and a body portion between the fastening portion and the support portion. The body portion includes: a first portion extending in a first direction; a second portion extending in the first direction and is between the first portion and the fastening portion; and a third portion which connects the first portion and the second portion. The first portion and the second portion are spaced apart from each other.

Backlight unit and display device including the same

The present disclosure relates to a light diffusion characteristic and a light reflection characteristic, and a light source device, a backlight unit, and an electronic device that include the lens. By causing the light emitted from the light source of the light source device to have both light diffusibility and light directivity using the lens including a lower layer portion having a light diffusion characteristic and an upper layer portion having a light reflection characteristic, it is possible to improve a light emission characteristic of the light source device, and when an optical gap is reduced due to the thickness reduction of the backlight unit, the image quality of the backlight unit can be improved.

Lens, light source device, backlight unit, and electronic device

Disclosed are a backlight unit and a display device including the same. The backlight unit and display device can minimize a change in an optical layer when exposed to hostile environments, such as high and low temperature environments. The backlight unit and the display device have a rigid structure, due to the minimized change in the optical layer even when exposed to hostile environments, such as high and low temperature environments.

Aspects disclosed herein relate to a diffuser plate supporter, a backlight unit, and an electronic device, in which a portion configured to support a diffuser plate in a diffuser plate supporter is made of a transparent material and a portion to be fastened to the cover bottom is made of an opaque material, so that the diffuser plate supporter can prevent light leakage from occurring on the back side of the cover bottom without interfering with light reaching the diffuser plate. In addition, through a reinforcement design for the boundary portion between the portion made of the transparent material and the portion made of the opaque material, it is possible to prevent the portions made of different materials from being separated from each other during rotational fastening of the diffusion plate supporter.

A diffuser sheet and display device having the same are provided. The diffuser sheet includes a base layer, a first skin layer on an upper surface of the base layer, and a second skin layer on a lower surface of the base layer. The base layer includes a base resin, a plurality of beads dispersed in the base resin, and a plurality of pores dispersed in the base resin.

Diffuser sheet having base layer with beads and pores and display device having the same

A monolithic diffuser plate for a backlight unit or a liquid crystal display (LCD) device can include a base substrate made of transparent glass, a monolithic diffusion sheet part integrated on a front surface of the base substrate, and a hiding diffusion part integrated on a rear surface of the base substrate for increasing a hiding power of the base substrate. The monolithic diffuser plate can increase a hiding power for hiding individual light sources in a backlight unit, prevent deformations caused by temperature variations and surrounding environmental factors, and minimize the thickness of a product using the monolithic diffuser plate while also increasing the reliability the product.

Monolithic diffuser plate, and backlight unit and liquid crystal display device using the same

Disclosed herein are an LED package module capable of lowering the price of manufacture by simply reducing the number of LED packages without decreasing the luminance, and a display device having the same. To this end, in an LED package module according to an exemplary embodiment of the present disclosure and a display device having the same, a plurality of LED packages is mounted on an LED module substrate in a matrix such that the LED packages are oriented in intersecting directions alternately in each of the longitudinal and lateral directions. Consequently, it is possible to increase price competitiveness by simply reducing the number of LED packages without degrading the display quality.

Light emitting diode package module and display device having the same

A transparent liquid crystal display device includes a liquid crystal display panel displaying an image in an image display mode and transparently implementing in a transparent mode; a backlight unit including a light guide plate disposed on a rear surface of the liquid crystal display panel and a light source array disposed at one side of the light guide plate; a light source driving unit supplying a driving current to the light sources; a cover bottom enclosing an edge of the side and rear surfaces of the backlight unit; and an illumination sensor measuring illumination of an external light incident to the rear surface of the cover bottom.
