This application claims priority under 35 U.S.C. § 119 from Korean Patent Application No. 10-2006-23068, filed on Mar. 13, 2006, in the Korean Intellectual Property Office, the entire content of which is incorporated herein by reference.
The controller 3 includes a power supply, an inverter, a main control board, all sorts of electric elements and sensors, etc., which are not shown in the drawing, and controls a whole operation of the LCD apparatus. The frame 4 is provided with a front frame part 4 a to which the liquid crystal panel 1 is mounted, and a rear frame 4 b arranged behind the front frame part 4 a.
Between the frame 4 and the backlight module 2 are arranged a first shield 8 to surround the backlight module 2 and the liquid crystal panel 1, and a second shield 9 to surround the controller 3.
FIG. 3 is a cross section view exemplifying a LCD apparatus in accordance with another exemplary embodiment of the present invention; and
FIG. 4 is a magnified cross section view of a portion IV of FIG. 3.
The rear housing part 32 is mounted at a rear side of the backlight module 20, so that it is arranged to be either in contact or adjacent to, but not being in contact with the LED light source 21 of the backlight module 20 (see FIG. 4).
The rear frame part 42 is configured, such that it is either in contact or adjacent to, but not contacting with the LED light source 21 of the liquid crystal panel assembly 100.
a backlight module having at least one light emitting diode (LED) light source which irradiates light to the liquid crystal panel; and
a housing which surrounds the liquid crystal panel and the backlight module,
wherein at least a portion of the housing adjacent to the at least one LED light source is formed of a thermal-conductive material.
2. The liquid crystal panel assembly as claimed in claim 1,
wherein the housing comprises a front housing part which exposes a screen of the liquid crystal panel to the outside, and a rear housing part arranged at a rear side of the backlight module,
wherein the rear housing part is formed of a thermal-conductive material.
3. The liquid crystal panel assembly as claimed in claim 2, wherein the rear housing part is arranged to surround the at least one LED light source.
4. The liquid crystal panel assembly as claimed in claim 1, wherein the backlight module further comprises:
a light guide plate which guides light from the at least one LED light source;
a diffusing plate which diffuses light from the light guide plate to the liquid crystal panel; and
a reflecting plate to which reflects light from the light guide plate to the diffusing plate.
5. The liquid crystal panel assembly as claimed in claim 4, wherein the at least one LED light source of the backlight module comprises a pair of LED light sources arranged symmetrically to each other at both sides of the light guide plate.
a liquid crystal panel assembly comprising a liquid crystal panel, and a backlight module having at least one light emitting diode (LED) light source which irradiates light to the liquid crystal panel; and
wherein at least a portion of the frame adjacent to the at least one LED light source is formed of a thermal-conductive material.
7. The liquid crystal display apparatus as claimed in claim 6,
wherein the frame comprises a front frame part which exposes a screen of the liquid crystal panel to the outside, and a rear frame part arranged behind the front frame part,
wherein the rear frame part is formed of a thermal-conductive material.
8. The liquid crystal display apparatus as claimed in claim 7, wherein the rear frame part is formed of a thermal and electric-conductive material.
9. The liquid crystal display apparatus as claimed in claim 6,
wherein the liquid crystal panel assembly further comprises a housing which surrounds the liquid crystal panel and the backlight module,
10. The liquid crystal display apparatus as claimed in claim 9,
11. The liquid crystal display apparatus as claimed in claim 10, wherein the rear housing part is arranged to surround the at least one LED light source.
12. The liquid crystal display apparatus as claimed in claim 10,
wherein the frame comprises a front frame part which exposes the screen of the liquid crystal panel to the outside, and a rear frame part arranged behind the front frame part,
wherein the rear frame part is formed of a thermal-conductive material, the rear frame part being in contact with the rear housing part.
a frame to which the liquid crystal panel assembly is mounted, the frame being formed of a thermal-conductive material.
14. The liquid crystal panel assembly as claimed in claim 2, wherein the rear housing part is arranged to be in contact with at least a portion of the at least one LED light source.
15. The liquid crystal panel assembly as claimed in claim 3, wherein the rear housing part is adjacent to, but not in contact with the at least one LED light source.
16. The liquid crystal display apparatus as claimed in claim 7, wherein the rear frame part is arranged to be in contact with at least a portion of the at least one LED light source.
17. The liquid crystal display apparatus as claimed in claim 7, wherein the rear frame part is arranged to be adjacent to, but not in contact with the at least one LED light source.
