140 : 탑 섀시140: top chassis

상기와 같은 목적을 달성하기 위한 본 발명의 몰드프레임에 체결된 바텀 섀시의 이탈 방지 구조는 내부에 백라이트 및 LCD 패널이 수납된 몰드프레임과, 상기 백라이트의 램프 어셈블리가 수납된 영역과 대응되는 상기 몰드프레임의 양측면과 배면에 결합되기 위해 소정형상으로 절곡된 바텀 섀시와, 상기 몰드프레임의 가장자리 소정영역과 상기 몰드프레임의 외측면 및 상기 몰드프레임의 측면에 위치한 상기 바텀 섀시의 측면을 감싸며 상기 몰드프레임과 결합되는 탑 섀시로 구성된 액정표시장치에 있어서, 상기 탑 섀시에 의해 감싸지는 바텀 섀시의 일측면에 반대되는 위치의 바텀 섀시가 상기 몰드프레임 배면의 소정부위에 형성되어 있는 고정홈에 체결되도록 ㄷ 자 형태로 절곡되어 있는 것을 특징으로 한다.The separation prevention structure of the bottom chassis fastened to the mold frame of the present invention for achieving the above object is a mold frame in which the backlight and the LCD panel is accommodated, and the mold corresponding to the area in which the lamp assembly of the backlight is accommodated The bottom frame bent in a predetermined shape to be coupled to both sides and the rear surface of the frame, and the mold frame surrounding the side surface of the bottom chassis located on a predetermined area of the edge of the mold frame and the outer surface of the mold frame and the mold frame And a top chassis coupled to the top chassis, wherein the bottom chassis opposite to one side of the bottom chassis covered by the top chassis is fastened to a fixing groove formed in a predetermined portion of the mold frame back surface. It is characterized by being bent in the shape of a ruler.

Will not.

이하, 도면을 참조하여 본 발명에 따른 몰드프레임에 체결된 바텀 섀시의 이탈 방지 구조를 도면을 참조하여 상세히 설명한다.Hereinafter, the departure-avoidance structure of the bottom chassis fastened to the mold frame according to the present invention with reference to the drawings will be described in detail with reference to the drawings.

도 4는 본 발명의 몰드프레임에 쳬결된 바텀 섀시의 이탈 방지 구조를 적용한 액정표시장치의 사시도이고, 도 5는 도 4의 B 부분 단면도이다.4 is a perspective view of a liquid crystal display device to which a separation prevention structure of a bottom chassis connected to a mold frame of the present invention is applied, and FIG. 5 is a partial cross-sectional view of FIG. 4.

내부에 수납공간이 형성되고 단방향 측면에 나사홀(142)이 형성된 몰드프레임(110)에 램프 어셈블리, 반사판, 도광판, 시트류로 구성된 백라이트(120)가 삽입 고정되고, 시트류(128)의 상부에는 백라이트(120)에서 전달된 빛을 이용하여 정보를 디스플레이하는 LCD 패널이 놓여진다.The backlight 120 including the lamp assembly, the reflector, the light guide plate, and the sheet is inserted into and fixed to the mold frame 110 having the storage space formed therein and the screw hole 142 formed at the unidirectional side, and the upper portion of the sheet 128.

즉, 상기 바텀 섀시(130)는 ㄷ 자 형상으로 절곡되어 있으며, 절곡된 일면(130b)은 상기 고정홈에 체결되고 또 다른 절곡된 면(130a)은 몰드프레임(110)의 장방향 측면에 위치하고 바텀 섀시(130)의 타면(130c)은 몰드프레임(110)의 하부면과 바텀 섀시 고정용 나사(132)에 의해 결합된다.That is, the bottom chassis 130 is bent in a c-shape, the bent one surface 130b is fastened to the fixing groove and the other bent surface 130a is located at the long side of the mold frame 110. The other surface 130c of the bottom chassis 130 is coupled to the bottom surface of the mold frame 110 by the bottom chassis fixing screw 132.

따라서, 액정표시장치에 외부의 충격이 가해질 때, 특히 여러 방향에서의 충격이 인가되었을 때, 본 발명의 액정표시장치는 바텀 섀시가 바텀 섀시 고정용 나사에 의해 고정되는 한편, 상기 나사에 의해 고정된 방향과 직각되는 방향에 있어서 고정홈에 의해 상기 바텀 섀시가 고정됨으로써 바텀 섀시의 밀리는 현상이 방지된다.Accordingly, when an external shock is applied to the liquid crystal display device, particularly when an impact in various directions is applied, the liquid crystal display device of the present invention is fixed by the screw while the bottom chassis is fixed by the bottom chassis fixing screw. The bottom chassis is prevented from being pushed by the bottom chassis being fixed by the fixing groove in a direction perpendicular to the direction of rotation.

One surface 130a of the bottom chassis 130 in contact with the inner surface of the top chassis 140 is in contact. In addition, a screw hole 142 is formed in a single direction of the top chassis 140 so as to correspond to a screw hole 142 formed in a single direction of the mold frame 110. The mold frame 110 and the top chassis are formed by screws 144. The 140 is fixed to prevent the top chassis 140 from being separated from the mold frame 110.

이와 같이 구성된 본 발명의 몰드프레임에 쳬결된 바텀 섀시의 이탈 방지 구조를 적용한 액정표시장치의 조립과정은 종래 구조와 마찬가지로, 몰드프레임(110)의 측면에 램프 어셈블리(122)를 설치하고 바텀 섀시(130)를 고정한 다음, 몰드프레임(110)의 수납공간에 반사판, 도광판, 시트류를 차례대로 적층시킨 후에 시트류(128)의 상부에 LCD 패널을 올려놓는다. 이후, 탑 섀시(140)를 몰드프레임(110)의 상부면에서 덮은 후 탑 섀시(130)의 장방향 측면에 형성된 후크 결합홈에 몰드프레임(110)의 후크(도시하지 않음)를 끼워 몰드프레임(110)에 탑 섀시(130)를 체결한다.The assembly process of the liquid crystal display device applying the departure prevention structure of the bottom chassis connected to the mold frame of the present invention configured as described above, the lamp assembly 122 is installed on the side of the mold frame 110 and the bottom chassis ( After fixing the 130, the reflective plate, the light guide plate, and the sheets are sequentially stacked in the storage space of the mold frame 110, and then the LCD panel is placed on the sheets 128.
