백라이트유닛의 패널장착구조{A PANEL MOUNTING STRUCTURE OF BACKLIGHT UNIT}Panel mounting structure of backlight unit {A PANEL MOUNTING STRUCTURE OF BACKLIGHT UNIT}

본 발명은 백라이트유닛의 패널장착구조에 관한 것으로, 더욱 상세하게는 백라이트유닛의 패널과 광학시트 사이에 구비되는 스페이스패널의 양면에 접착수단을 구비하여 상기 패널을 스페이스패널에 부착되도록 함으로써 탑새시를 구비하지 않고도 패널을 고정할 수 있는 백라이트유닛의 패널장착구조에 관한 것이다.The present invention relates to a panel mounting structure of a backlight unit, and more particularly, to provide a top chassis by attaching the panel to the space panel by providing an adhesive means on both sides of the space panel provided between the panel and the optical sheet of the backlight unit. It relates to a panel mounting structure of the backlight unit that can be fixed to the panel without having.

최근 정보기술과 이동통신기술 등의 발전과 함께 정보를 시각적으로 표시해줄 수 있는 디스플레이장치가 비약적으로 발전하고 있다. 디스플레이장치는 크게 발광특성을 갖는 자체발광형 디스플레이와 외부의 요인에 의해 발광하는 비발광형 디스플레이로 분류된다.Recently, with the development of information technology and mobile communication technology, a display device capable of visually displaying information is rapidly developing. Display apparatuses are largely classified into self-luminous displays having luminescent properties and non-luminous displays emitting light by external factors.

엘시디(Liquid Crystal Display, LCD)는 비발광형 디스플레이장치로, 자체발광기능을 갖지 못한 소자이므로 별도의 광원이 필요하다. 따라서 엘시디의 배면에 광원을 구비한 백라이트유닛(Backlight Unit)이 마련되어 엘시디를 향해 빛을 조사하고 이를 통해서 화상이 구현된다.LCD (Liquid Crystal Display, LCD) is a non-light-emitting display device, because the device does not have a self-light-emitting function requires a separate light source. Therefore, a backlight unit having a light source is provided on the back of the LCD to emit light toward the LCD, thereby realizing an image.

백라이트유닛은 광원으로 냉음극형광램프(Cold Cathode Fluorescent Lamp, CCFL), 외부전극형광램프(External Electrode Fluorescent Lamp) 또는 발광다이오드(Light Emitting Diode, LED) 등이 사용되며, 특히 LED는 소형, 저전력, 고신뢰성 등의 장점이 있어 광원으로서 널리 이용되고 있다.The backlight unit is used as a cold light source (Cold Cathode Fluorescent Lamp, CCFL), External Electrode Fluorescent Lamp (LED) or Light Emitting Diode (LED). It has advantages such as high reliability and is widely used as a light source.

도 1은 종래기술에 따른 조광형 백라이트유닛의 전체적인 구성을 나타내는 분해사시도이고, 도 2는 종래기술에 따른 측면 조광형 백라이트유닛의 단면도이다.1 is an exploded perspective view showing the overall configuration of a dimming backlight unit according to the prior art, Figure 2 is a cross-sectional view of the side dimming backlight unit according to the prior art.

도 1 및 도 2를 참조하면, 종래기술에 따른 측면 조광형 백라이트유닛은 보텀새시(10)와 안착새시(20) 및 탑새시(30)를 포함하여 구성되며, 상기 탑새시(30)가 나사와 같은 별도의 체결구에 의하여 보텀새시(10)에 직접 결합되거나 체결구 없이 탑새시(30)가 보텀새시(10)를 수납하는 방식에 의하여 결합된다. 안착새시(20)는 안착플레이트(21)와 장착플레이트(22) 및 접촉플레이트(23)를 포함하여 구성된다.1 and 2, the side dimming backlight unit according to the related art includes a bottom chassis 10, a seating chassis 20, and a top chassis 30, and the top chassis 30 is provided with a screw. The top chassis 30 is directly coupled to the bottom chassis 10 by a separate fastener such as, or coupled to the bottom chassis 10 without the fastener. The mounting chassis 20 includes a mounting plate 21, a mounting plate 22, and a contact plate 23.

보텀새시(10)에는 도광판(40)과 광학시트(50) 및 패널(60)이 순차적으로 수용되고, 안착새시(20)는 보텀새시(10)의 측면(11) 내측에 장착되고 상단부에는 광학시트(50)가 장착된다. 탑새시(30)는 안착새시(20)의 상단부에 안착되는 패널(60)의 일측을 고정하고, 보텀새시(10)의 측면(11)의 외측의 하부측 가장자리를 타측에서 고정한다.The bottom chassis 10 receives the light guide plate 40, the optical sheet 50, and the panel 60 sequentially, and the seating chassis 20 is mounted inside the side surface 11 of the bottom chassis 10 and has an optical portion at an upper end thereof. The seat 50 is mounted. The top chassis 30 fixes one side of the panel 60 seated at the upper end of the seating chassis 20, and fixes the lower edge of the outer side of the side 11 of the bottom chassis 10 from the other side.

안착플레이트(21)는 도광판(40)의 가장자리 부분이 안착되고, 장착플레이트(22)는 상기 안착플레이트(21)의 가장자리로부터 연장되어 보텀새시(10)의 측면(11) 내측에 접촉하여 엘이디바(70)가 장착되며, 접촉플레이트(23)는 장착플레이트(22)의 단부로부터 연장되어 패널(60)의 가장자리와 접촉하게 된다. 패널(60)의 양측에는 스페이스패널(80)이 구비되어 상기 패널(60)이 요동하거나 이탈되는 것을 방지한다.
The seating plate 21 is mounted on the edge portion of the light guide plate 40, and the mounting plate 22 extends from the edge of the seating plate 21 to contact the inner side 11 of the bottom chassis 10 so as to contact the LED bar. 70 is mounted, and the contact plate 23 extends from the end of the mounting plate 22 to be in contact with the edge of the panel 60. Space panels 80 are provided at both sides of the panel 60 to prevent the panel 60 from swinging or falling off.

종래기술에 따른 백라이트유닛의 패널장착구조에 따르면 패널의 전면에 탑새시가 구비되어 패널을 고정하기 때문에 탑새시 및 그 조립공정이 별도로 필요하고, 상기 탑새시로 인하여 패널의 일부가 가려지기 때문에 화면이 크기가 줄어들 뿐만 아니라 디자인적인 측면에서도 감성품질을 떨어뜨리는 문제점이 있다.According to the panel mounting structure of the backlight unit according to the prior art, because the top chassis is provided on the front of the panel to fix the panel, the top chassis and its assembling process are required separately, and a part of the panel is covered by the top chassis. Not only is this size reduced, but there is also a problem of degrading the emotional quality in terms of design.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 패널과 광학시트 사이이에 구비되는 스페이스패널의 양면에 접착제 또는 양면테이프 등과 같은 접착수단이 구비되여 광학시트와 패널을 고정할 수 있도록 함으로써 탑새시가 구비되지 않더라도 패널의 고정이 가능한 백라이트유닛의 패널장착구조를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, the top chassis is provided with an adhesive means such as adhesive or double-sided tape on both sides of the space panel provided between the panel and the optical sheet to fix the optical sheet and the panel. It is an object of the present invention to provide a panel mounting structure of a backlight unit, which is capable of fixing a panel even if it is not provided.

상기의 목적을 달성하기 위한 기술적 사상으로서의 본 발명은, 보텀새시와, 상기 보텀새시의 측면 내측에 장착되는 안착새시와, 상기 안착새시의 내측벽에 구비되는 엘이디바와, 상기 안착새시의 내측에 구비되는 도광판과, 상기 도광판의 상부에 구비되는 광학시트와, 상기 안착새시의 상부에 구비되는 패널과, 상기 패널 및 상기 광학시트 사이에 구비되는 스페이스패널을 포함하여 구성되는 백라이트유닛에 있어서, 상기 스페이스패널은 양측면에 접착수단이 구비되어 상기 패널이 상기 광확시트에 부착ㆍ고정되도록 하는 것을 특징으로 한다.The present invention as a technical concept for achieving the above object is provided with a bottom chassis, a seating chassis mounted on the side inner side of the bottom chassis, an LED bar provided on the inner wall of the seating chassis, and the inside of the seating chassis. A light guide plate, an optical sheet provided on an upper portion of the light guide plate, a panel provided on an upper portion of the seating chassis, and a space panel provided between the panel and the optical sheet. The panel is provided with adhesive means on both sides so that the panel is attached and fixed to the light diffusing sheet.

본 발명에 따른 백라이트유닛의 패널장착구조에 의하며, 탑새시가 구비되지 않더라도 패널이 고정되기 때문에 탑새시와 상기 탑새시를 조립하는 공정이 생략될 수 있어서 생산원가를 절감할 수 있는 이점이 있다. 또한 종래와 같이 탑새시가 패널의 일부를 가리지 않기 때문에 디스플레이장치의 전면이 더욱 넓고 세련되게 보여 감성품질을 향상시킬 수 있는 이점이 있다.According to the panel mounting structure of the backlight unit according to the present invention, since the panel is fixed even if the top chassis is not provided, the process of assembling the top chassis and the top chassis can be omitted, thereby reducing the production cost. In addition, since the top chassis does not cover a part of the panel as in the related art, the front surface of the display device may be more wide and stylish, thereby improving the sensitivity quality.
