Backlight unit and display device having the same

摘要

A display device includes a display panel and a backlight unit. The display panel is curved along a first direction. The backlight unit includes an upper surface, and a lower surface having a curvature different from a curvature of the upper surface. The backlight unit includes a bottom cover that includes a bottom portion, and a sidewall extending from the bottom portion, a plurality of light emitting diodes on the bottom portion and generating light, and a diffusion plate on the light emitting diodes. In the first direction from a center portion of the bottom portion to an outer portion of the bottom portion, pitches between the light emitting diodes along a surface of the bottom portion, are proportional to distances between the light emitting diodes and the diffusion plate in a direction substantially normal to positions of the bottom portion at which the light emitting diodes are disposed.

主权项

1. A display device comprising:
a display panel curved along a first direction, and configured to display an image; and a backlight unit configured to provide a light to the display panel, the backlight unit comprising:
a bottom cover comprising:
a bottom portion which is curved along the first direction, anda sidewall which extends from the bottom portion;a plurality of light emitting diodes on the bottom portion and configured to generate the light; anda diffusion plate on an upper end of the sidewall and curved along the first direction,whereina curvature of the bottom portion is larger than a curvature of the diffusion plate, andin the first direction along the curvature of the bottom portion, as a distance from a center portion of the bottom portion to an outer portion of the bottom portion increases,
pitches between the light emitting diodes decrease, andfor the light emitting diodes for which pitches therebetween decrease, distances between the light emitting diodes and the diffusion plate in a direction substantially normal to positions of the bottom portion at which the light emitting diodes decrease.
