Backlight unit and liquid crystal display using the same
View Patent ↗A backlight unit is suitable for emitting uniform surface light. The backlight unit comprises a lamp emitting light to an incident light side of a light guide plate, and a lamp housing enclosing the lamp and including a heat sink.
1. A backlight unit, comprising:
a lamp emitting light to an incident light side of a light guide plate; and
a lamp housing partially surrounding the lamp and including a heat sink,
wherein the heat sink is disposed in the inside of the lamp housing, and
wherein the heat sink includes at least one phase change material and a plurality of capsules for encapsulating for the phase change material.
2. The backlight unit as claimed in claim 1 , wherein the phase change material is selected from alkanes hydrocarbons.
3. The backlight unit as claimed in claim 1 , wherein the phase change material includes at least one of octadecane and nonadecane belonging to alkanes hydrocarbons.
4. The backlight unit as claimed in claim 1 , wherein the capsule is formed of melanin resin.
5. A liquid crystal display, comprising:
a liquid crystal panel; and
a backlight unit including a light guide plate that guides light from a lamp to the liquid crystal panel, and a lamp housing partially surrounding the lamp and including a heat sink,
wherein the heat sink is disposed in the inside of the lamp housing, and
wherein the heat sink includes at least one phase change material and a plurality of capsule for encapsulating the phase change material.
6. The liquid crystal display as claimed in claim 5 , wherein the phase change material is selected from alkanes hydrocarbons.
7. The liquid crystal display as claimed in claim 5 , wherein the phase change material includes at least one of octadecane and nonadecane belonging to alkanes hydrocarbons.
8. The liquid crystal display as claimed in claim 5 , wherein the capsule is formed of melanin resin.
