Plasma display apparatus having a bent chassis base
US 7777400 B2
A plasma display apparatus is a type of flat display apparatus used to display an image by using a gas discharge phenomenon, and is being spotlighted as a next-generation image display device because it can be made to have a thin thickness of several centimeters or below, a wide screen and a wide viewing angle of 150° or above.
The chassis base 40, which is generally a flat panel and has an edge bent in a “
” (or 90°) shape, supports the PDP 20 and dissipates heat transmitted from the PDP 20.
In order to solve such a problem, reinforcement members 50 are installed on a rear surface of the chassis base 40. The reinforcement members 50 are connected to parts of the rear surface of the chassis base 40 in a “
” (or 90° or 180° bend) shape to thereby reinforce the chassis base 40. The reinforcement members 50 arranged at edges of the rear surface of the chassis base 40 function also as seat plates for supporting signal-transmission members 70 such as tape carrier packages (TCP) that are widely used for electrically connecting the PDP 20 and the circuit board 60.
A heat conductive member 192′ may be formed between at least the device 175 and the second bent part 152. The heat conductive member 192′ not only attaches the device 175 to the second bent part 152 but also exhausts heat generated from the device 175 to the outside. Further, since the temperature of the device 175 increases up to about 70° C. through 90° C., the heat conductive member 192′ may advantageously have high heat conductivity.
Shown in FIG. 4 heat conductive member 192″ is formed between at least the device 175 and an inner surface of the element seat groove Hc. The heat conductive member 192″ not only attaches the device 175 to the element seat groove Hc but also exhausts heat generated from the device 175 to the outside. Here, since the temperature of the device 175 increases up to about 70° C. through 90° C., the heat conductive member 192″ may have high heat conductivity. The heat conductive member 192″ may be a liquid or gel-type conductive medium such as a grease, or may also be a solid flat heat exhaust member. Other types of heat conductive members 192′ may also be used.
As shown in FIGS. 2 and 5, connection brackets 145 may be connected between neighboring extended bent parts 150, for example, between an upper extended bent part 150 and the left and right extended bent parts 150, and between a lower extended bent part 150 and the left and right extended bent parts 150. The connection bracket 145 has both end portions each having a connection groove 145 h formed corresponding to the first, second and third bent parts 151, 152 and 153, and is bent by 90°. The connection bracket 145 connects the neighboring extended bent parts 150, to thereby further improve the rigidity of the chassis base 140, and protect the corner portions of the base 141. The connection bracket 145 may be made of materials such as, but not limited to a rigid plastic.
