And, by inserting and fixing the sheets 23 for condensing and diffusing the light guided by the light guide plate 21, and the LCD panel 25 for displaying information, the outer surface of the mold frame 10 by a predetermined interval A plurality of hooks 13 are formed.
탑샤시(30)는 램프 구조물, 도광판(21), 시트류(23), LCD 패널(25)등이 몰드프레임(10)에서 이탈되는 것을 방지하기 위해 몰드프레임(10)의 상부에 덮여 몰드프레임(10)과 체결되는 것으로, 탑샤시(30)의 소정영역, 즉 후크(13)와 대응되는 영역에는 후크(13)를 삽입하여 고정하는 삽입홀(33)이 형성되어 있다.The top chassis 30 is covered on the upper part of the mold frame 10 to prevent the lamp structure, the light guide plate 21, the sheets 23, the LCD panel 25, etc. from being separated from the mold frame 10. It is fastened to the (10), the insertion hole 33 for inserting and fixing the hook 13 is formed in a predetermined region of the top chassis 30, that is, the region corresponding to the hook (13).
여기서, 몰드프레임(10)과 탑샤시(30)의 체결 과정은 도 1b에 도시된 바와 같이 몰드프레임(10)의 일측면 또는 대응되는 양측면에 램프 구조물을 삽입하고 도광판(21)과 시트류(23)와 LCD 패널(25)을 차례대로 적층시킨다. 이후, 몰드프레임(10)의 상부면에 탑샤시(30)를 덮고 몰드프레임(10)의 장방향 쪽에 형성된 후크(13)를 먼저 탑샤시(30)의 삽입홀(33)에 끼운 후에 몰드프레임(10)의 단방향 쪽에 형성된 후크(13)를 탑샤시(30)의 삽입홀(33)에 끼워 몰드프레임(10)과 탑샤시(30)를 체결한다.Here, the fastening process of the mold frame 10 and the top chassis 30 is inserted into the lamp structure on one side or corresponding both sides of the mold frame 10, as shown in Figure 1b and the light guide plate 21 and the sheet ( 23) and the LCD panel 25 are laminated in this order.

여기서, 몰드프레임(110)은 램프 구조물, 도광판(121), 시트류(123), LCD 패널(125)을 삽입 고정하는 것으로, 몰드프레임(110)의 장방향 외측면에는 소정깊이의 슬라이딩 홈(113)이 장방향 측면을 따라 길게 연장되어 있다. 또한, 슬라이딩 홈(113)의 일단에는 걸림턱(115)이 형성된다. Here, the mold frame 110 inserts and fixes the lamp structure, the light guide plate 121, the sheets 123, and the LCD panel 125, and has a sliding groove having a predetermined depth in the longitudinal outer surface of the mold frame 110. 113 extends long along the longitudinal side. In addition, the locking jaw 115 is formed at one end of the sliding groove 113.
탑샤시(130)는 램프 구조물, 도광판(121), 시트류(123), LCD 패널(125) 등이 몰드프레임(110)에서 이탈되는 것을 방지하기 위해 몰드프레임(110)에 체결되는 것으로, 탑샤시(130)의 장방향 내측면에는 슬라이딩 홈(113)과 대응되도록 슬라이딩 돌출부(133)가 길게 연장되어 있다. 또한, 슬라이딩 돌출부(133)의 일단에는 걸림턱(115)과 되응되도록 걸림홈(135)이 형성된다. The top chassis 130 is fastened to the mold frame 110 to prevent the lamp structure, the light guide plate 121, the sheets 123, and the LCD panel 125 from being separated from the mold frame 110. The sliding protrusion 133 extends long on the longitudinally inner side surface of the chassis 130 to correspond to the sliding groove 113. In addition, at one end of the sliding protrusion 133, a locking groove 135 is formed to correspond to the locking jaw 115.
이와 같이 형성된 몰드프레임과 탑샤시의 체결 과정을 설명하면 다음과 같다.Referring to the fastening process of the mold frame and the top chassis formed as described above are as follows.
먼저, 몰드프레임(110)의 일측면 또는 대응되는 양측면에 LCD 패널(125)에 빛을 조사하는 램프 구조물을 삽입하고, 램프 구조물의 측면에 발산된 빛을 LCD 패널(125) 쪽으로 안내하는 도광판(121)을 위치시킨다. 이후, 도광판(121)의 상부면에 도광판(121)에서 안내된 빛을 집광하고 확산하는 시트류(123)를 삽입하고, 시트류(125)의 상부면에 정보를 디스플레이하는 LCD 패널(125)을 위치시킨다. First, a lamp structure for irradiating light to the LCD panel 125 is inserted into one side or corresponding both sides of the mold frame 110, and a light guide plate for guiding light emitted from the side of the lamp structure toward the LCD panel 125 ( 121). Subsequently, the LCD panel 125 inserts sheets 123 for condensing and diffusing light guided by the LGP 121 on the upper surface of the LGP 121 and displays information on the upper surface of the sheet 125. Locate it.
이어서, 램프구조물, 도광판(121), 시트류(123), LCD 패널(125)등이 몰드프레임(110)에서 이탈되는 것을 방지하기 위해 몰드프레임(110)을 탑샤시에 슬라이딩시켜 몰드프레임(110)과 탑샤시(130)를 체결한다. 이때, 탑샤시(130)의 슬라이딩 돌출부(133)를 몰드프레임(110)의 슬라이딩 홈(113)에 끼운 후 걸림홈(135)이 형성되어 있지 않은 쪽으로 몰드프레임(110)을 밀어 슬라이딩시키면 마지막에 걸림홈(135)과 걸림턱(115)이 결합되므로 탑샤시(130)가 몰드프레임(110)에서 이탈하지 않는다.Subsequently, in order to prevent the lamp structure, the light guide plate 121, the sheets 123, and the LCD panel 125 from being separated from the mold frame 110, the mold frame 110 is slid to the top chassis to mold the mold frame 110. ) And the top chassis 130 are fastened. At this time, the sliding protrusion 133 of the top chassis 130 is inserted into the sliding groove 113 of the mold frame 110, and then slides the mold frame 110 toward the side where the locking groove 135 is not formed. Since the locking groove 135 and the locking jaw 115 are coupled, the top chassis 130 does not leave the mold frame 110.
이와 같이 몰드프레임(110)에 슬라이딩 홈(113)을 형성하고 탑샤시(130)에 슬라이딩 돌출부(133)를 형성할 경우 체결면적이 증가되므로 몰드프레임(110)과 탑샤시(130)의 결합강도가 증다된다.As such, when the sliding groove 113 is formed in the mold frame 110 and the sliding protrusion 133 is formed in the top chassis 130, the coupling area is increased, so that the bonding strength between the mold frame 110 and the top chassis 130 is increased. Is increased.
이상에서 설명한 바와 같이 본 발명은 몰드프레임의 외측면에 슬라이딩 홈을 형성하고 탑샤시의 내측면에 슬라이딩 홈에 끼워지는 슬라이딩 돌출부를 형성하여 슬라이딩 방식으로 몰드프레임과 탑샤시를 체결함으로써, LCD 모듈에 가해지는 충격에 의해서 체결부가 파손되는 것을 방지할 수 있고, LCD 모듈의 조립 및 분리를 용이하게 할 수 있어 작업효율이 상승되는 효과가 있다.As described above, the present invention forms a sliding groove on the outer side of the mold frame and forms a sliding protrusion fitted to the sliding groove on the inner side of the top chassis to fasten the mold frame and the top chassis in a sliding manner, The fastening part can be prevented from being damaged by an impact applied thereto, and the assembly and disassembly of the LCD module can be easily performed, thereby increasing work efficiency.
