Abstract

본 발명은 액정표시장치의 백커버 체결 구조에 관한 것으로, 몰드프레임의 삽입홀에 가이드홈을 형성하여 백커버를 슬라이딩 방식으로 몰드프레임에 체결함으로써 백커버의 강도를 보강할 수 있는 효과가 있다. 즉, 가이드홈이 백커버의 가장자리 소정영역을 전체적으로 지지하고 있기 때문에 외부에서 가해진 충격을 몰드프레임으로 분산시킬 수 있어 백커버가 충격에 의해 몰드프레임에서 이탈하는 것을 방지할 수 있다. The present invention relates to a back cover fastening structure of a liquid crystal display device, by forming a guide groove in an insertion hole of a mold frame and fastening the back cover to the mold frame in a sliding manner to reinforce the strength of the back cover. That is, since the guide groove entirely supports the predetermined region of the edge of the back cover, the impact applied from the outside can be distributed to the mold frame, thereby preventing the back cover from being separated from the mold frame by the impact.

또한, 슬라이딩 방식에 의해 몰드프레임에 체결된 백커버의 일단에만 나사가 삽입되어 있기 때문에 나사의 불균일한 체결에 의해 백커버가 들뜨거나 휘어지는 현상을 방지할 수 있고, 나사의 수를 줄일 수 있어 제조비용의 절감 및 작업의 능률이 향상될 수 있다.In addition, since the screw is inserted only at one end of the back cover fastened to the mold frame by the sliding method, it is possible to prevent the back cover from being lifted or bent due to the uneven fastening of the screw and to reduce the number of screws. Cost reduction and work efficiency can be improved.

Description

액정표시장치LCD Display

본 발명은 액정표시장치에 관한 것으로서, 더욱 상세하게는 슬라이딩(sliding) 방식으로 백커버를 몰드프레임의 후면에 체결하여 작업의 용이성 및 백커버의 기계적 강도를 증대시킨 액정표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device in which a back cover is fastened to a rear surface of a mold frame in a sliding manner to increase ease of work and mechanical strength of the back cover.

액정표시장치의 백라이트 장치에서 램프 어셈블리의 역할과 기능은 갈수록 중요한 과제로 대두되고 있다. 이는 램프 어셈블리의 구조에 따라서 TFT-LCD 모듈(module)의 크기와 중량 및 광량 등이 달라져 TFT-LCD 모듈의 기계적, 광학적 특성에 많은 영향을 미치기 때문이다.The role and function of the lamp assembly in the backlight device of the liquid crystal display device is an increasingly important problem. This is because the size, weight, quantity of light, etc. of the TFT-LCD module are changed according to the structure of the lamp assembly, which greatly affects the mechanical and optical characteristics of the TFT-LCD module.

이와 같은 이유로 인해 램프 어셈블리의 교체 또한 중요한 과제로 대두되고 있는데, 이는 교체 전과 교체 후의 램프 어셈블리 성능이 동일해야 하고 램프 어셈블리의 교체시 다른 부품이 손상되지 않아야 하기 때문이다. 이러한 문제를 해결하기 위해 램프 어셈블리 자체를 하나의 세트로 만들어 도광판 일측면에 슬라이딩 방식으로 램프 어셈블리를 삽입하거나 몰드프레임 하부에서 도광판 일측에 수직으로 램프 어셈블리를 끼워 넣는 방식이 많이 사용되고 있다. 후자의 경우 램프 어셈블리를 지지하고 보호하기 위한 목적으로 몰드프레임의 하부면에 백커버를 체결한다. For this reason, the replacement of the lamp assembly is also an important task, since the lamp assembly performance must be the same before and after the replacement and other components must not be damaged when the lamp assembly is replaced. In order to solve this problem, a lamp assembly itself is made into a set and a lamp assembly is inserted into one side of the light guide plate by sliding, or a lamp assembly is vertically inserted into one side of the light guide plate from the bottom of the mold frame. In the latter case, the back cover is fastened to the lower surface of the mold frame for the purpose of supporting and protecting the lamp assembly.

도 1을 참조하여 이를 좀더 상세히 설명하면, 램프 어셈블리, 도광판, 시트류, LCD 패널등을 지지하는 몰드프레임(10)의 하부면 소정영역(램프 어셈블리가 위치해 있는 영역)에 램프 어셈블리를 몰드프레임 내부에 용이하게 삽입하기 위한 삽입홀이 형성되어 있다.In more detail with reference to Figure 1, the lamp assembly in the predetermined region (region where the lamp assembly is located) the lower surface of the mold frame 10 for supporting the lamp assembly, light guide plate, sheets, LCD panel, etc. An insertion hole is formed to easily insert into the.

몰드프레임(10)의 하부면에 형성된 삽입홀을 통해 램프 어셈블리가 수직 방향으로 몰드프레임의 내부에 삽입되면 램프 어셈블리를 지지하고 보호하기 위해서 바(bar) 형상의 백커버(20)를 삽입홀에 덮어 삽입홀을 폐쇄시킨다. When the lamp assembly is inserted into the mold frame in the vertical direction through the insertion hole formed in the lower surface of the mold frame 10, the bar-shaped back cover 20 is inserted into the insertion hole to support and protect the lamp assembly. Cover to close the insertion hole.

이와 같이 백커버(20)에 의해서 삽입홀이 폐쇄되면 몰드프레임(10)과 백커버(20)의 양단에 고정바(30)를 위치시키고 나사(31)를 이용하여 백커버(20)를 몰드프레임(10)에 체결한다.As such, when the insertion hole is closed by the back cover 20, the fixing bars 30 are positioned at both ends of the mold frame 10 and the back cover 20, and the back cover 20 is molded using the screws 31. Fasten to the frame (10).

그러나, 액정표시장치의 경량·박형화의 추세에 따라 백커버의 두께 또한 계속 얇아지고 있으며 이로 인해 백커버의 강도가 약화되어 외부에서 발생된 충격에 의해 쉽게 휘어지거나 충격 테스트시 몰드프레임을 이탈하여 램프를 파손시키는 문제점이 있었다. 전자의 경우를 좀더 상세히 설명하면, 백커버를 몰드프레임에 고정시키기 위해서 백커버 양단에 삽입되는 나사의 체결력이 서로 불균일하여 백커버의 일단이 들뜨거나 휘어지며 이로 인해 빛샘 현상이 발생된다.However, in accordance with the trend of lighter and thinner liquid crystal display devices, the thickness of the back cover continues to become thinner. As a result, the strength of the back cover is weakened. There was a problem of breaking. If the former case is described in more detail, in order to fix the back cover to the mold frame, the fastening force of the screws inserted at both ends of the back cover is uneven, so that one end of the back cover is lifted or bent, and thus light leakage occurs.

또한, 백커버를 체결하기 위해서는 2개 이상의 나사가 필요함으로 제조비용이 상승되고 작업능률이 저하되는 문제점이 있었다. In addition, since two or more screws are required to fasten the back cover, there is a problem in that manufacturing cost is increased and work efficiency is lowered.

따라서, 본 발명의 목적은 상기와 같은 문제점을 감안하여 안출된 것으로서, 슬라이딩 방식을 이용하여 백커버를 몰드프레임에 체결함으로써 백커버의 강도를 보강하고 제조비용의 절감 및 작용의 능률을 향상시키도록 한 액정표시장치를 제공 하는데 있다.Therefore, an object of the present invention is devised in view of the above problems, by fastening the back cover to the mold frame using a sliding method to reinforce the strength of the back cover and to reduce the manufacturing cost and improve the efficiency of the operation It is to provide a liquid crystal display device.

And the LCD panel 170 installed on the upper surface of the sheet 160 and displaying information.

여기서, 몰드프레임(110)의 하부면 소정영역, 즉 램프 어셈블리(120)가 위치해 있는 영역에는 도 2 및 도 3에 도시된 바와 같이 램프 어셈블리(120) 보다 길이가 긴 삽입홀(113)이 형성되어 있다. 또한, 삽입홀(113)의 내측면 길이방향에는 백커버(130)를 가이드하는 요철형상의 가이드홈(115)이 형성되어 있으며, 삽입홀(113)의 일단, 즉 백커버(130)가 제일 먼저 삽입되는 일단과 소정간격 이격된 영역에 암나사부(117)가 형성되어 있다. Here, an insertion hole 113 having a longer length than the lamp assembly 120 is formed in a predetermined region of the lower surface of the mold frame 110, that is, the region where the lamp assembly 120 is located. It is. In addition, in the longitudinal direction of the inner surface of the insertion hole 113 is formed a guide groove 115 of the uneven shape for guiding the back cover 130, one end of the insertion hole 113, that is, the back cover 130 is the first The female screw part 117 is formed in the area | region which is spaced apart from the one end inserted first.

한편, 백커버(130)는 도 3에 도시된 바와 같이 삽입홀(113)을 폐쇄시키도록 소정 폭을 갖는 직사각형상의 바이며 백커버(130)의 일단, 즉 몰드프레임(110)에 형성된 암나사부(117)와 대응되는 위치에 암나사부(137)가 설치되어 있다.On the other hand, the back cover 130 is a rectangular bar having a predetermined width to close the insertion hole 113, as shown in Figure 3, one end of the back cover 130, that is, female thread formed in the mold frame 110 The female thread part 137 is provided in the position corresponding to 117.

도 3을 참조하여 본 발명에 의한 백커버 체결 방법을 설명하면 다음과 같다.Referring to Figure 3 describes the back cover fastening method according to the present invention.

몰드프레임(110)의 내부에 반사판, 도광판, 시트류, LCD 패널등을 순차적으로 설치한 후에 몰드프레임(110)의 하부면에 형성되어 있는 삽입홀(113)을 통해 램프 어셈블리(미도시)를 몰드프레임(110)의 일측면에 삽입한다. 이후, 램프 어셈블리(120)를 외부 환경으로부터 보호하기 위해 백커버(130)를 삽입홀(113)에 슬라이딩시켜 몰드프레임(110)에 체결시킨다. 이를 좀더 상세히 설명하면 도 3에 도시된 바와 같이 삽입홀(113)의 내측면에 형성되어 있는 가이드홈(115)에 백커버(130)의 일단 소정영역을 삽입한 후에 삽입홀(113)이 폐쇄되는 방향으로 백커버(130)를 밀어 넣는다. After the reflective plate, the light guide plate, the sheets, the LCD panel, etc. are sequentially installed in the mold frame 110, the lamp assembly (not shown) is inserted through the insertion hole 113 formed in the lower surface of the mold frame 110. Inserted into one side of the mold frame (110). Thereafter, in order to protect the lamp assembly 120 from the external environment, the back cover 130 is slid into the insertion hole 113 to be fastened to the mold frame 110. More specifically, as shown in FIG. 3, the insertion hole 113 is closed after inserting a predetermined region of the back cover 130 into the guide groove 115 formed in the inner surface of the insertion hole 113.

When the back cover 130 is fastened to the mold frame 110 by applying the sliding method as described above, the guide groove 115 formed in the insertion hole 113 supports the predetermined region of the edge of the back cover 130 as a whole. Strengthen the back cover 130. In addition, since the guide groove 115 supports the back cover 130 and only one end of the back cover 130 is screwed, the back cover 130 may be prevented from being bent or lifted.

이상에서 설명한 바와 같이 본 발명은 몰드프레임의 삽입홀에 가이드홈을 형성하여 백커버를 슬라이딩 방식으로 몰드프레임에 체결함으로써 백커버의 강도를 보강할 수 있는 효과가 있다. 즉, 가이드홈이 백커버의 가장자리 소정영역을 전체적으로 지지하고 있기 때문에 외부에서 가해진 충격을 몰드프레임으로 분산시킬 수 있어 백커버가 충격에 의해 몰드프레임에서 이탈하는 것을 방지할 수 있는 효과가 있다. As described above, the present invention has an effect of reinforcing the strength of the back cover by forming a guide groove in the insertion hole of the mold frame and fastening the back cover to the mold frame in a sliding manner. That is, since the guide groove entirely supports the predetermined area of the edge of the back cover, the impact applied from the outside can be distributed to the mold frame, thereby preventing the back cover from being separated from the mold frame by the impact.

또한, 슬라이딩 방식에 의해 몰드프레임에 체결된 백커버의 일단에만 나사가 삽입되어 있기 때문에 나사의 불균일한 체결에 의해 백커버가 들뜨거나 휘어지는 현상을 방지할 수 있고, 나사의 수를 줄일 수 있어 제조비용의 절감 및 작업의 능률이 향상될 수 있는 효과가 있다.In addition, since the screw is inserted only at one end of the back cover fastened to the mold frame by the sliding method, it is possible to prevent the back cover from being lifted or bent due to the uneven fastening of the screw and to reduce the number of screws. There is an effect that the cost can be reduced and the work efficiency can be improved.
