Description
본 발명은 플라즈마 디스플레이 장치에 관한 것으로서, 더욱 상세하게는 플라즈마 디스플레이 패널(plasma display panel)로부터 발생되는 열이 패널을 구동하는 회로기판으로 전달되는 것을 차단하는 구조를 구비하는 플라즈마 디스플레이 장치에 관한 것이다.The present invention relates to a plasma display device, and more particularly, to a plasma display device having a structure that blocks heat generated from a plasma display panel from being transferred to a circuit board for driving the panel.
플라즈마 디스플레이 장치는 가스 방전현상을 이용하여 화상을 표시하는 평판 디스플레이 장치로서, 표시용량, 휘도, 콘트라스트, 잔상 및 시야각 등의 각종 표시 능력이 우수하며, 박형이고 대화면 표시가 가능하여 음극선관(CRT)을 대체할 수 있는 차세대 대형 평판 디스플레이 장치로서 각광을 받고 있다.Plasma display device is a flat panel display device that displays images by using gas discharge phenomenon. It has excellent display capability such as display capacity, brightness, contrast, afterimage and viewing angle, and is thin and can display large screen. It is attracting attention as the next generation large flat panel display device that can replace the.
도 1에는 이러한 일반적인 플라즈마 디스플레이 장치의 일례를 개략적으로 나타낸 분리 사시도가 도시되어 있다.1 is an exploded perspective view schematically showing an example of such a general plasma display device.
일반적으로 플라즈마 디스플레이 장치는, 가스 방전을 이용하여 문자나 이미지를 표현하며 전면기판(11)과 배면기판(12)을 포함하는 플라즈마 디스플레이 패널(10)과, 그 배면에 배치되는 샤시(20), 및 샤시(20)의 배면에 배치되며 플라즈마 디스플레이 패널(10)을 구동하는 회로기판(30)을 구비한다.In general, the plasma display apparatus may include a plasma display panel 10 including a front substrate 11 and a rear substrate 12 and a chassis 20 disposed on a rear surface thereof to express characters or images by using gas discharge. And a circuit board 30 disposed on the rear surface of the chassis 20 and driving the plasma display panel 10.
일반적인 플라즈마 디스플레이 장치에 있어서 열을 발생시키는 주요 구성 요소는 플라즈마 디스플레이 패널(10)과 회로기판(30)이다. 플라즈마 디스플레이 패널(10)에서 발생되는 열은 주로 열전도율이 높은 샤시(20)로 전달되어 외부로 방출되는데, 그 일부는 회로기판(30)으로 전달된다. 회로기판(3)은 플라즈마 디스플레이 패널(10)을 구동하는 구동소자(미도시)를 포함하며, 최근에는 구동회로의 신뢰성 및 생산성을 향상시키기 위하여 여러 가지의 반도체 소자를 하나의 기판에 집적한 하이브리드 집적회로(hybrid integrated circuit)를 사용하고 있는 추세이다. 상기 하이브리드 집적회로는 내부에 발열소자가 집중되어 있기 때문에, 구동 시 고열을 발생하게 된다. 이와 같이 발생된 열은 반도체 소자와 같은 회로부품의 구동 특성을 저하시킨다. 특히, 플라즈마 디스플레이 장치는 음극선관과는 달리 좁은 공간에서 박형으로 화상을 형성하도록 구성되어 있기 때문에, 집적회로에서 발생한 열을 외부로 방출시키기 위한 별도의 냉각장치를 필요로 한다.In a typical plasma display device, the main components that generate heat are the plasma display panel 10 and the circuit board 30. Heat generated in the plasma display panel 10 is mainly transferred to the chassis 20 having high thermal conductivity and released to the outside, and part of the heat is transferred to the circuit board 30. The circuit board 3 includes a driving device (not shown) for driving the plasma display panel 10. Recently, in order to improve the reliability and productivity of the driving circuit, a hybrid in which various semiconductor devices are integrated on one substrate. The trend is to use hybrid integrated circuits. In the hybrid integrated circuit, since heat generating elements are concentrated therein, high heat is generated during driving. The heat generated in this way degrades the driving characteristics of circuit components such as semiconductor devices. In particular, unlike the cathode ray tube, the plasma display device is configured to form an image in a narrow space in a narrow space, and thus requires a separate cooling device for dissipating heat generated in an integrated circuit to the outside.
그런데, 상기와 같이 구성된 종래의 플라즈마 디스플레이 장치에 있어서는 샤시(20) 위에 회로기판(30)을 직접 접촉함으로써, 샤시(20)가 플라즈마 디스플레이 패널(10)에서 발생하는 열을 회로기판(30)에 직접 전달하는 매체가 되고 있다. 이러한 구조는 샤시(20)의 방열을 방해하기 때문에 플라즈마 디스플레이 패널(10) 잔상 등의 불량을 유발할 뿐만 아니라, 회로기판(30)으로 전달된 열이 회로에 영향을 주어 안정적인 회로 동작을 저해하게 함으로써, 신뢰성을 떨어뜨리는 문제점이 있었다.However, in the conventional plasma display device configured as described above, by directly contacting the circuit board 30 on the chassis 20, the heat generated from the plasma display panel 10 by the chassis 20 is transferred to the circuit board 30. It has become a direct delivery medium. Since such a structure prevents the heat dissipation of the chassis 20, not only causes an afterimage of the plasma display panel 10 such as an afterimage, but also heat transmitted to the circuit board 30 affects the circuit, thereby inhibiting stable circuit operation. There was a problem that degrades reliability.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 샤시의 배면과 회로기판 사이에 단열 수단을 삽입하여 플라즈마 디스플레이 패널로부터 발생하는 열이 회로 기판으로 전달되는 것을 차단함으로써 안정적인 회로 동작을 가능하도록 하는 플라즈마 디스플레이 장치를 제공하는데 있다. 본 발명의 다른 목적은 방열 능력이 우수한 요철 형상의 샤시를 배치함으로써 플라즈마 디스플레이 패널로부터 전달되는 열의 방출을 촉진하는 플라즈마 디스플레이 장치를 제공하는데 있다.The present invention is to solve the above problems, an object of the present invention is to insert a heat insulation means between the back of the chassis and the circuit board to prevent the heat generated from the plasma display panel to be transferred to the circuit board stable circuit operation It is to provide a plasma display device that enables. Another object of the present invention is to provide a plasma display device which promotes the release of heat transferred from the plasma display panel by disposing an uneven chassis having excellent heat dissipation ability.
상기와 같은 목적 및 그 밖의 다른 목적을 달성하기 위하여, 본 발명은 플라즈마 디스플레이 패널, 상기 플라즈마 디스플레이 패널의 배면에 배치되는 샤시, 상기 샤시의 배면에 배치되는 회로기판, 및 상기 회로기판과 상기 샤시의 사이에 위치하는 단열 수단을 포함하는 플라즈마 디스플레이 장치를 제공한다.In order to achieve the above object and other objects, the present invention provides a plasma display panel, a chassis disposed on the rear surface of the plasma display panel, a circuit board disposed on the rear surface of the chassis, and the circuit board and the chassis. It provides a plasma display device including a heat insulating means located between.
본 발명에 있어서 상기 단열 수단은 바람직하게는 적어도 하나의 단열판으로 이루어질 수 있다.In the present invention, the heat insulating means may be preferably made of at least one heat insulating plate.
본 발명에 있어서 상기 샤시는 바람직하게는 전면 또는 배면 중 적어도 어느 하나의 면에 요입부와 요철부가 교번하도록 요철 형상으로 절곡될 수 있다.In the present invention, the chassis may be bent in a concave-convex shape so that the concave portion and the concave-convex portion alternate on at least one surface of the front or rear.
본 발명에 있어서 바람직하게는 상기 돌출부의 양측면에 요철부가 형성되도록 할 수 있다.In the present invention, preferably, uneven parts may be formed on both side surfaces of the protrusion.
본 발명에 있어서 바람직하게는 상기 돌출부의 양측면에 다수의 휜이 구비되도록 할 수 있다.In the present invention, a plurality of fins may be provided on both side surfaces of the protrusion.
본 발명에 있어서 상기 돌출부와 상기 요입부는 바람직하게는 사다리꼴 형태가 될 수 있다.In the present invention, the protrusion and the indentation may be preferably trapezoidal.
이어서, 첨부된 도면들을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다. Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2에는 본 발명의 바람직한 일 실시예에 따른 플라즈마 디스플레이 장치의 개략적인 분리 사시도가 도시되어 있다. 도면을 참조하면, 플라즈마 디스플레이 장치는, 가스 방전을 이용하여 문자나 이미지를 표현하며 전면기판(11)과 배면기판(12)을 포함하는 플라즈마 디스플레이 패널(10)과, 그 배면에 배치되는 샤시(20), 및 샤시(20)의 배면에 배치되며 플라즈마 디스플레이 패널(10)을 구동하는 회로기판(30)을 구비하며, 추가적으로 샤시(20)와 회로기판(30) 사이에 단열 수단(40)이 삽입되어 있다. 단열 수단(40)은 도 3a에 도시된 바와 같이, 하나의 단열판(41) 모양으로 할 수도 있고, 도 3b에 도시된 바와 같이 회로기판(30)의 수를 고려하여 둘 이상의 단열판(41)으로 분리되어 삽입될 수 있다. 다수개의 단열판(41)을 삽입할 경우 단열판(41)과 샤시(20)와의 접촉 면적이 작아지므로, 샤시(20)의 방열 면적이 증가되어 샤시(20)의 방열 능력이 향상된다.2 is a schematic exploded perspective view of a plasma display device according to an exemplary embodiment of the present invention. Referring to the drawings, the plasma display apparatus includes a plasma display panel 10 including a front substrate 11 and a rear substrate 12 and representing a character or an image using gas discharge, and a chassis disposed on the rear surface thereof. 20, and a circuit board 30 disposed on the rear surface of the chassis 20 and driving the plasma display panel 10, and additionally, a heat insulating means 40 is provided between the chassis 20 and the circuit board 30. It is inserted. As shown in FIG. 3A, the heat insulating means 40 may be in the shape of one heat insulating plate 41, and as shown in FIG. 3B, the heat insulating means 40 may be formed into two or more heat insulating plates 41 in consideration of the number of circuit boards 30. Can be inserted separately. When the plurality of heat insulating plates 41 are inserted, the contact area between the heat insulating plates 41 and the chassis 20 is reduced, so that the heat dissipation area of the chassis 20 is increased to improve the heat dissipation capability of the chassis 20.
더욱이, 회로기판(30)과 샤시(20) 사이에 단열판(41)이 개재되므로, 플라즈마 디스플레이 패널(10)에서 발생된 열이 회로기판(30)으로 전달되는 것을 차단할 수 있어, 회로기판(30) 내에서 회로가 열에 의해 오동작되는 것을 방지할 수 있게 된다.In addition, since the heat insulating plate 41 is interposed between the circuit board 30 and the chassis 20, heat generated in the plasma display panel 10 can be prevented from being transferred to the circuit board 30, thereby providing a circuit board 30. The circuit can be prevented from malfunctioning due to heat.
또한, 플라즈마 디스플레이 패널(41)은 플라즈마 디스플레이 장치의 주된 히트 소스(heat source)인 플라즈마 디스플레이 패널(10)과 회로기판(30)의 방열을 단열판(41)을 경계로 하여 독립적으로 수행하도록 할 수 있게 해주기 때문에, 플라즈마 디스플레이 장치의 설계자들의 방열 방법에 대한 설계 자유도가 증대된다.In addition, the plasma display panel 41 may independently perform heat dissipation of the plasma display panel 10 and the circuit board 30, which are the main heat sources of the plasma display device, with the insulation plate 41 as a boundary. This increases the design freedom of the designers of the plasma display device in the heat dissipation method.
샤시(20)는, 도 4에 도시된 바와 같이, 플라즈마 디스플레이 패널(10)로부터의 전달된 열의 방출을 촉진시키기 위해 요철 형상으로 절곡되어 있는 것이 바람직하다. 이와 같은 구성을 갖는 샤시(20)는 증가된 열전달 면적을 갖게 되어 방열 능력이 향상된다. 또한, 요철 형상을 갖는 샤시(20)의 경우, 송풍기(미도시)에 의한 강제 대류가 생성되어 방열될 때뿐만 아니라, 송풍기(미도시)없이 자연 대류에 의해서 방열될 경우에도, 샤시(20)로부터 열전달을 받아 온도가 상승한 공기가 요입부(53)와 돌출부(52)에 형성된 통풍홈(61)을 따라서 자연스럽게 흐르도록 해 주기 때문에 방열 능력이 향상된다. As shown in FIG. 4, the chassis 20 is preferably bent into a concave-convex shape in order to promote the release of the transferred heat from the plasma display panel 10. The chassis 20 having such a configuration has an increased heat transfer area, thereby improving heat dissipation capability. In addition, in the case of the chassis 20 having a concave-convex shape, the chassis 20 is not only when the forced convection by the blower (not shown) is generated and radiated, but also when the heat is radiated by natural convection without the blower (not shown). Since the air whose temperature has risen by heat transfer from the air flows naturally along the ventilation grooves 61 formed in the concave portions 53 and the protrusions 52, the heat dissipation ability is improved.
도 5a에는 플라즈마 디스플레이 패널(10)의 세로 방향으로 통풍홈(61)이 형성된 요철 형상의 샤시(20)가 도시되어 있다. 샤시(20)로부터 열전달을 받은 공기는 온도가 상승하여 부력 효과에 의해 통풍홈(61)을 따라 위쪽으로 원활하게 방출될 수 있기 때문에 방열 능력을 증대시킨다. 또한, 요철 형상에 의해 증가된 열전달 면적과 통풍홈(61)에 의한 공기 유로는 샤시(20)의 방열 능력을 증대시킨다.FIG. 5A illustrates a chassis 20 having an uneven shape in which a ventilation groove 61 is formed in the longitudinal direction of the plasma display panel 10. Air received heat transfer from the chassis 20 is increased in temperature and can be smoothly discharged upward along the ventilation groove 61 by the buoyancy effect to increase the heat dissipation ability. In addition, the heat transfer area increased by the concave-convex shape and the air flow path by the ventilation grooves 61 increase the heat dissipation capability of the chassis 20.
도 5b에는 플라즈마 디스플레이 패널(10)의 가로 방향으로 통풍홈(61)이 형성된 요철 형상의 샤시(20)가 도시되어 있다. 일반적으로 회로기판(30)과 플라즈마 디스플레이 패널(10)이 FPCB(flexible printed circuit board)(미도시)를 매개로 하여 연결되는데, FPCB는 샤시(20)의 상부측면 또는 하부측면을 통하여 연장된다. 만일 고온의 공기가 FPCB와 접촉하게 되면 열전달에 의해 FPCB에 형성되어 있는 회로와 FPCB에 실장된 전기소자에 악영향을 줄 수 있다. 따라서, 샤시(20)에 가로 방향으로 통풍홈(61)을 형성시키게 되면, 샤시(20)로부터 열전달을 받은 고온의 공기가 통풍홈(61)을 따라 샤시(20)의 좌우측 방향으로 배출되어, FPCB와의 직접적인 접촉을 하지 않으므로 FPCB가 안정적으로 작동할 수 있게 된다.5B illustrates a chassis 20 having an uneven shape in which a ventilation groove 61 is formed in a horizontal direction of the plasma display panel 10. In general, the circuit board 30 and the plasma display panel 10 are connected through a flexible printed circuit board (FPCB) (not shown). The FPCB extends through the upper side or the lower side of the chassis 20. If hot air comes into contact with the FPCB, heat transfer may adversely affect the circuits formed in the FPCB and the electrical elements mounted on the FPCB. Therefore, when the ventilation grooves 61 are formed in the chassis 20 in the horizontal direction, hot air, which has received heat transfer from the chassis 20, is discharged in the left and right directions of the chassis 20 along the ventilation grooves 61, Since there is no direct contact with the FPCB, the FPCB can operate stably.
도 6a는 요철 형상의 샤시의 돌출부(52)에 요철(54)을 형성시킨 것을 나타낸다. 열전달 면적의 추가적인 증가로 방열 능력이 증대된다.FIG. 6A shows that the unevenness 54 is formed in the protrusion 52 of the uneven shape chassis. Further increase in heat transfer area results in increased heat dissipation.
또한, 도 6b에 도시된 바와 같이 요철 형상의 샤시(20)의 돌출부(52)에 휜(fin)(55)을 설치함으로써 열전달 면적을 증가시켜 방열 능력을 증가시킬 수 있다.In addition, as shown in Figure 6b by providing a fin (55) in the protrusion 52 of the uneven shape chassis 20 can increase the heat transfer area to increase the heat dissipation capacity.
도 7은 사다리꼴 형상의 요철(56)을 나타낸다. 사다리꼴 형상의 요철(56)의 경우도 사각형 형상의 요철처럼 열전달 면적이 증가할 뿐만 아니라, 열전달되는 통풍홈(61)의 유로가 매끄럽게 형성되기 때문에 방열 능력이 우수해 진다.7 shows the trapezoidal irregularities 56. In the case of the trapezoidal irregularities 56, the heat transfer area is increased as well as the rectangular irregularities, and the heat dissipation ability is excellent because the flow path of the ventilation groove 61 to be transferred is smoothly formed.
도 8에는 바둑판 모양의 양각 돌출부(57)를 가진 샤시(20)의 일부 사시도를 나타낸다. 바둑판 모양의 양각 돌출부(57)는 돌출된 부분으로 인하여 평판에 비해 열전달 면적이 증가하여 방열 능력이 향상된다. 또한, 통풍 유로가 플라즈마 디스플레이 패널(10)의 가로 방향뿐만 아니라 세로 방향으로도 형성되어, 샤시(20)로부터 열전달을 받은 고온의 공기가 외부로 원활하게 유출되므로 샤시(20)의 방열 능력을 증가시킨다.8 shows a partial perspective view of the chassis 20 with a checkerboard-shaped embossed protrusion 57. The embossed protrusion 57 of the checkerboard shape has an increased heat transfer area due to the protruding portion, thereby improving heat dissipation ability. In addition, the ventilation channel is formed not only in the horizontal direction but also in the vertical direction of the plasma display panel 10, so that the hot air, which has received heat transfer from the chassis 20, smoothly flows out to the outside, thereby increasing the heat dissipation capability of the chassis 20. Let's do it.
상술한 바와 같은 본 발명의 플라즈마 디스플레이 장치에 의하면 다음과 같은 효과가 있다.According to the plasma display device of the present invention as described above has the following advantages.
첫째, 샤시와 회로기판 사이에 단열 수단을 삽입함으로써 플라즈마 디스플레이 패널로부터 발생하는 열이 회로기판에 전달되어 회로의 오동작이 발생하는 것을 억제한다.First, by inserting a heat insulation means between the chassis and the circuit board, heat generated from the plasma display panel is transferred to the circuit board to suppress the malfunction of the circuit.
둘째, 단열 수단의 삽입으로 플라즈마 디스플레이 패널로부터 발생하는 열과 회로기판에서 발생하는 열을 분리하여 독립적으로 방출시킬 수 있으므로, 설계자들의 방열 설계의 자유도가 증대된다.Second, since the heat generated from the plasma display panel and the heat generated from the circuit board can be separated and discharged independently by the insertion of the heat insulating means, designers have more freedom of heat dissipation design.
셋째, 샤시를 요철 형상으로 형성하여 열전달 면적을 증가시킴으로 방열 능력이 향상된다. 또한, 요철의 돌출부의 양측면에 요철부를 형성하거나 다수의 휜을 설치함으로써 열전달 면적의 추가적인 증가로 방열 능력이 증대된다.Third, the heat dissipation ability is improved by increasing the heat transfer area by forming the chassis in an uneven shape. In addition, by forming an uneven portion or providing a plurality of fins on both sides of the protrusions of the unevenness, the heat dissipation ability is increased due to an additional increase in the heat transfer area.
넷째, 샤시에 요철 형상에 의한 통풍홈을 세로 방향으로 형성할 경우, 자연 대류에 의하여 샤시로부터 열전달을 받은 고온의 공기가 원활하게 외부로 배출되므로, 열전달 효과가 증대되어 방열능력이 향상된다. 또한, 통풍홈을 가로 방향으로 형성할 경우, 샤시의 상부측면 또는 하부측면에 위치하는 FPCB가 샤시로부터 열전달을 받은 고온의 공기에 의해 악영향을 받는 것을 감소시킬 수 있다.Fourth, when the ventilation grooves having the uneven shape in the chassis are formed in the vertical direction, since the hot air received from the chassis by natural convection is smoothly discharged to the outside, the heat transfer effect is increased and the heat dissipation ability is improved. In addition, when the ventilation grooves are formed in the horizontal direction, the FPCB located on the upper side or the lower side of the chassis can be reduced from being adversely affected by the hot air that receives heat transfer from the chassis.
다섯째, 샤시와 회로기판 사이에 단열수단을 개재시킴으로 인해 샤시의 방열성이 떨어지는 것을 샤시의 형상을 요철 형상으로 함으로써 방지 할 수 있다.Fifth, the heat dissipation of the chassis is reduced by interposing a heat insulating means between the chassis and the circuit board, thereby preventing the chassis from having an uneven shape.
