LIGHT EMITTING UNIT WITH HIGH LIGHT SPREADING ANGLE, BACKLIGHT ASSEMBLY HAVING THE SAME, AND DISPLAY APPARATUS

摘要

A backlight assembly includes a light emitting unit, a reflective sheet, and a bottom cover. The light-emitting unit includes a light source emitting light and an optical system. The optical system is spaced apart from the light source in a direction in which the light emitted from the light emitting unit initially travels. The optical system has a curved shape that reflects a portion of the light emitted from the light source and transmits a remaining portion of the light emitted from the light source. The reflective sheet is disposed under the light-emitting unit to re-reflect the light reflected by the optical system. The bottom cover accommodates the light emitting unit and the reflective sheet. Thus, the light-spreading angle of the light-emitting unit becomes wide.

主权项

1. A light emitting unit comprising:
a light source emitting light predominantly in a first direction; and an optical system spaced apart from the light source with respect to the first direction, the optical system having a curved shape reflecting a portion of the light emitted from the light source and transmitting a remaining portion of the light emitted from the light source therethrough.
