Description

엘씨디 패널용 지지대{SUPPORTER FOR LCD PANEL} Support for LCD panel {SUPPORTER FOR LCD PANEL}

본 발명은 영상표시장치에 관한 것으로, 상세하게는 반사판과 확산판 사이에 결합되어 반사판으로부터 확산판의 간격을 일정하게 유지시키는 지지대의 선단에 탄성을 갖는 지지부를 형성함으로써 확산판의 스크레치나 지지대의 열변형에 의한 확산판의 처짐을 방지할 수 있도록 구성한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device. Specifically, the present invention relates to an image display device. Specifically, an elastic support portion is formed at a tip of a support that is coupled between a reflector and a diffuser plate to maintain a constant gap between the reflector and a diffuser plate. It is configured to prevent sagging of the diffusion plate due to thermal deformation.

일반적으로 TFT(thin-film transistor) 패널이나 PDP(plasma display panel)와 함께 TV나 컴퓨터용 모니터와 같은 고화질 대화면의 영상표시장치로 널리 쓰이는 엘씨디(Liquid Crystal Display) 패널은 TFT 패널이나 PDP 패널보다 전력소모가 작고 선명환 화상의 재현이가능하여 차세대의 디스플레이 패널로 각광을 받고 있다.In general, liquid crystal display (LCD) panels, which are widely used as high-definition screen displays such as TVs and computers, together with thin-film transistor (PDP) panels or plasma display panels (PDPs), have higher power than TFT or PDP panels. It is consumed as a next-generation display panel because it consumes less and can reproduce clear images.

상기한 엘씨디 패널은 수광장치인 관계로 화상의 표시를 위한 백라이트를 필요로 하게 되는데, 이와 같은 엘씨디 패널은 상기한 백라이트 배열에 따라 에지형과 직하형으로 구분되며, TV나 컴퓨터용 모니터에서는 높은 효율과 함께 대화면의 구현이 가능한 관계로 직하형 엘씨디 패널을 사용한다.Since the LCD panel is a light receiving device, a backlight for displaying an image is required. The LCD panel is classified into an edge type and a direct type according to the backlight arrangement, and is highly efficient in a TV or a computer monitor. In addition, the direct LCD panel is used because the large screen can be implemented.

도 1은 상기한 직하형 엘씨디 패널의 일례를 도시한 단면도로서, 이와 같은 엘씨디 패널(200)은, 조사된 빛을 전방으로 반사시키는 장방형의 반사판(120) 정면으로부터 원통형상의 백라이트 램프(L)가 등간격으로 배열되며, 상기한 백라이트 램프(L)의 정면으로는 백라이트 램프(L)로부터 조사된 빛을 산란시켜 빛의 발산이 균일하게 이루어지도록 한 확산판(130)이 결합된다.1 is a cross-sectional view showing an example of the direct type LCD panel. The LCD panel 200 includes a cylindrical backlight lamp L from a front surface of the rectangular reflector 120 that reflects the irradiated light to the front. The diffusion plates 130 are arranged at equal intervals, and the front side of the backlight lamp L scatters the light emitted from the backlight lamp L so that light is uniformly emitted.

또한, 상기한 확산판(130)의 정면으로는 엘씨디 패널(200)의 휘도를 향상시키기 위한 프리즘 시트(140)가 결합되며, 상기한 프리즘 시트(140)의 정면에 엘씨디 패널(200)의 외부를 구성하는 투명한 재질의 프런트 커버(150)가 결합된다.In addition, the front of the diffusion plate 130 is coupled to the prism sheet 140 for improving the brightness of the LCD panel 200, the outside of the LCD panel 200 on the front of the prism sheet 140. Front cover 150 of the transparent material constituting the combination.

이와 함께 반사판(110)의 배면으로는 재현되는 영상신호에 따라 상기한 백라이트 램프(L)에 동작전원을 인가하는 도시안된 회로기판이 결합되며, 측면으로는 각 구성부품을 고정지지하는 동시에, 각 구성부품을 보호하기 위한 금속재의 프레임(160)이 결합된다.In addition, a circuit board (not shown) for applying operating power to the backlight lamp L is coupled to the rear surface of the reflector 110 in accordance with the reproduced video signal. The metal frame 160 to protect the component is coupled.

이때, 상기한 확산판(130)은 백라이트 램프(L)로부터 조사된 빛이 표면으로 균일하게 전달될 수 있도록 백라이트 램프(L)로부터 일정하게 이격된 상태로 결합이 이루어지며, 이와 함께 자중이나 고온에 의한 변형 등을 방지할 수 있도록 반사판(120)과 확산판(130) 사이에 다수의 지지대(110)가 결합된다.At this time, the diffusion plate 130 is coupled in a constant spaced state from the backlight lamp (L) so that the light irradiated from the backlight lamp (L) can be uniformly transmitted to the surface, together with its own weight or high temperature A plurality of supports 110 are coupled between the reflecting plate 120 and the diffusion plate 130 to prevent deformation due to.

이와 같은 지지대(110)는 적절한 강성을 유지하는 한편, 경량화를 위해 통상적으로 수지재를 사출시켜 구성하며, 특히 확산판(130)과의 접촉면적을 최소화함으로써 화면을 통한 노출이 방지될 수 있도록 예리한 각도를 갖는 원추형상으로 형성하여 점접촉에 의해 확산판(130)을 지지시킨다.The support 110 is configured by injecting a resin material in order to reduce the weight, while maintaining the proper rigidity, in particular, by minimizing the contact area with the diffuser plate 130 is sharp to prevent exposure through the screen It is formed in a conical shape having an angle to support the diffusion plate 130 by point contact.

상기한 바와 같이 수지재를 원추형상으로 사출시켜 구성한 종래의 지지대(110)는, 외부로부터 엘씨디 패널(200)에 충격이나 진동 등이 가해질 경우 상기한 지지대(110)의 선단이 확산판(130)과 밀착된 상태에서 초기의 지지위치로부터 유동함으로써 확산판(130)에 스크레치가 발생하는 등의 문제점이 발생한다.In the conventional support 110 configured by injecting a resin material into a conical shape as described above, when the impact or vibration is applied to the LCD panel 200 from the outside, the tip of the support 110 is diffused 130. In the state in close contact with the flow from the initial support position occurs a problem such as scratches in the diffusion plate 130.

이와 함께 종래의 지지대(110)는 선단이 예리한 각도의 원추형상으로 이루어짐으로써 외부로부터 가해진 충격에 의해 선단이 쉽게 파손됨에 따라 확산판(130)과 지지대(110) 사이에 공간이 형성됨에 따라 확산판(130)에 대한 지지력이 저하되어 확산판(130)이 처지게 되는 등의 많은 문제점이 발생한다.Along with this, the conventional support 110 is formed in a conical shape with a sharp tip, so that the tip is easily broken by an impact applied from the outside, so that a space is formed between the diffusion plate 130 and the support 110. Many problems occur, such as the support force for the 130 is lowered, such that the diffusion plate 130 sags.

한편, 상기한 바와 같이 수지재로 이루어진 지지대(110)의 문제점을 해결하기 위한 것으로, 국내 공개특허공보 특 2002-29842호로서 알려진 액정표시장치의 직하형 백라이트 어셈블리에서는, 지지대의 선단을 연성재질로 구성함으로써 확산판의 스크레치를 방지하고, 충격에 의한 지지대의 파손을 방지한다.On the other hand, to solve the problem of the support 110 made of a resin material as described above, in the direct type backlight assembly of the liquid crystal display device known as Korean Patent Application Laid-Open No. 2002-29842, the front end of the support is made of a flexible material The structure prevents scratches of the diffusion plate and prevents damage to the support base due to impact.

도 2는 상기한 바와 같이 지지대를 접촉부(201) 및 지지부(205)로 분할하여 구성한 액정표시장치의 직하형 백라이트 어셈블리의 지지대(220)를 도시한 단면도로서, 이와 같은 구조의 지지대(220)는, 확산판과 접하는 접촉부를 고무나 실리콘재와 같이 신축성을 갖는 소재로 구성하고, 상기한 접촉부(201)를 지지하는 지지부(205)를 수지재를 사출시켜 구성함으로써 확산판에 대한 스크레치의 발생을 방지하고, 선단의 파손을 방지한다.FIG. 2 is a cross-sectional view illustrating the support 220 of the direct backlight assembly of the liquid crystal display device configured by dividing the support into the contact portion 201 and the support 205 as described above. The contact portion in contact with the diffusion plate is made of elastic material such as rubber or silicone material, and the support portion 205 for supporting the contact portion 201 is formed by injecting a resin material to generate scratches on the diffusion plate. Prevents damage to the tip.

그러나 상기한 바와 같이 접촉부(201)를 연성재질로 구성한 종래의 지지대(210)는, 확산판의 스크레치를 방지하고, 선단의 파손을 방지할 수 있는 반면, 접촉부(201)가 확산판과의 마찰에 따라 박리됨으로써 확산판을 오염시키는 등의 문제점이 발생하며, 열에 의해 쉽게 변형됨에 따라 확산판에 대한 지지력이 저하되는 등의 많은 문제점이 발생한다.However, as described above, the conventional support base 210 having the contact portion 201 made of a flexible material can prevent scratches of the diffusion plate and prevent breakage of the tip, whereas the contact portion 201 is friction with the diffusion plate. As a result, problems such as contamination of the diffuser plate occur due to peeling, and many problems such as deterioration of bearing capacity for the diffuser plate occur due to being easily deformed by heat.

본 발명은 상기한 바와 같은 국내 공개특허공보 특 2002-29842호를 포함한 종래 구조의 지지대가 갖는 문제점을 해결하기 위한 것으로, 본 발명의 기술적 과제는, 반사판과 확산판 사이에 결합되어 반사판으로부터 확산판의 간격을 일정하게 유지시키는 지지대의 선단에 탄성을 갖는 지지부를 형성함으로써 외부로부터 엘씨디 패널에 진동이나 충격이 전달될 경우에도 확산판의 스크레치나 지지대의 열변형에 의한 확산판의 처짐 등을 방지할 수 있는 엘씨디 패널용 지지대를 제공하는 것이다.The present invention is to solve the problems of the support structure of the prior art including the above-described Korean Patent Publication No. 2002-29842, the technical problem of the present invention is coupled between the reflecting plate and the diffuser plate from the diffuser plate By forming an elastic support portion at the distal end of the support to keep the intervals constant, even if vibration or shock is transmitted to the LCD panel from the outside, the diffusion plate can be prevented from being scratched or the deflection of the diffusion plate due to thermal deformation of the support. It is to provide a support for the LCD panel.
