Backlight unit of liquid crystal display
First Claim
1. A backlight unit of a liquid crystal display, comprising:
- a plurality of light emitting diode packages arranged in a matrix while being spaced a uniform distance apart from each other, each light emitting diode package including one or more light emitting diode chips and structured such that light generated from the light emitting chips is emitted in the horizontal direction; and
a reflector consisting of a plurality of reflection cells connected to each other in a matrix, each of the reflection cells having each of the light generating packages positioned at the center of each of the reflection cells, having a unit size, and reflecting the light, emitted from the light emitting diode at the center thereof in the horizontal direction, to the perpendicular direction.

Abstract
Disclosed herein is a backlight unit of a liquid crystal display. The backlight unit comprises a plurality of light emitting diode packages arranged in a matrix while being spaced a uniform distance apart from each other, each light emitting diode package including one or more light emitting diode chips and structured such that light generated from the light emitting chips is emitted in the horizontal direction, and a reflector consisting of a plurality of reflection cells connected to each other in a matrix. Each of the reflection cells of a unit size has each of the light generating packages positioned at the center thereof, and reflects the light, emitted from the light emitting diode at the center thereof in the horizontal direction, to the perpendicular direction.

8. A backlight unit of a liquid crystal display, comprising a plurality of unit backlight cells connected to each other in a matrix, each of the plurality of unit backlight cells integrally comprising:
-
a printed circuit board having a conductive pattern for transmitting power formed thereon;
one or more light emitting diode chips electrically connected to the conductive pattern on the printed circuit board;
a lens for changing path of light generated from the light emitting diode chips to the horizontal direction; and
a reflector formed to surround the lens and having a unit size for reflecting the light refracted in the horizontal direction through the lens to the perpendicular direction. - View Dependent Claims (9, 10, 11, 12)
