본 발명은 평판형 형광램프의 제조 방법에 관한 것으로서, 더욱 상세하게는 한 개의 모기판에 적어도 2개 이상 복수개의 평판형 형광램프를 동시에 제조하는 방법에 관한 것이다. The present invention relates to a method for manufacturing a flat fluorescent lamp, and more particularly, to a method for simultaneously manufacturing at least two or more flat fluorescent lamps on one mother substrate.

일반적으로 엘시디 패널의 후면조명으로 사용되는 백라이트장치에는 평판형 형광램프를 사용하여 고휘도 및 고휘도 균일도를 얻고 있다. 평판형 형광램프는 설펀틴 형태의 형광램프로서 내부공간이 설펀틴 형태로 형성된 상판과 평판 형태인 하판을 상하 결합시키고, 결합된 내부공간에 형광체를 도포한 것으로서, 도 1 및 도 2를 참고하여 설명한다. In general, a backlight device used as a backlight of an LCD panel uses a flat fluorescent lamp to obtain high brightness and high brightness uniformity. The flat fluorescent lamp is a sulfentin-type fluorescent lamp, which combines the upper and lower plates formed in the sulfentin form with an inner space up and down, and applies a phosphor to the combined inner space, referring to FIGS. 1 and 2. Explain.

도 1은 일반적인 평판형 형광램프의 평면도이고, 도 2는 일반적인 평판형 형광램프의 단면도로서, 형광램프(100)는 상하로 분리되는 제1기판(110)과 제2기판(120)으로 구성되어 있다. 제1기판(110)에는 방전공간을 이루는 복수개의 채널(111)이 서로 나란하게 형성되도록 성형하고 있다. FIG. 1 is a plan view of a general flat fluorescent lamp, and FIG. 2 is a cross-sectional view of a general flat fluorescent lamp, wherein the fluorescent lamp 100 includes a first substrate 110 and a second substrate 120 that are separated up and down. have. The first substrate 110 is molded such that a plurality of channels 111 constituting the discharge space are formed to be parallel to each other.

상기 제1기판(110)은 통상 가열에 의하여 성형되는데, 종래에는 한 개의 기판에 한 개의 제1기판(110)을 성형하고 있으며, 상기 제1기판(110)을 성형할 때에는 복수개의 채널(111) 중 최 외곽에 성형되는 채널(111)에는 가스 주입 및 수은을 확산시키기 위한 가스 주입관(140)이 설치된다. The first substrate 110 is usually formed by heating. In the related art, one first substrate 110 is formed on one substrate, and a plurality of channels 111 are formed when the first substrate 110 is formed. In the outermost of the channel 111 is formed a gas injection tube 140 for gas injection and mercury diffusion.

한편 제2기판(120)은 직사각형의 평판형태를 갖는다. 상기 제1기판(110)과 제2기판(120)은 접착제(130)에 의하여 상하 결합하여 하나의 평판형 형광램프(100)를 구성한다. 상기 채널(111)의 내부에는 형광체가 도포되어 있다. Meanwhile, the second substrate 120 has a rectangular flat plate shape. The first substrate 110 and the second substrate 120 are coupled up and down by the adhesive 130 to form one flat fluorescent lamp 100. The phosphor is coated inside the channel 111.

따라서, 복수개의 채널(111)이 나란하게 성형된 제1기판(110)과 평판형태의 제2기판(120)의 둘레면에 접착제(130)를 도포한 후 통상 가열에 의하여 상기 접착 제(130)를 소성한다. Therefore, after the adhesive 130 is applied to the circumferential surfaces of the first substrate 110 and the second substrate 120 having a plate shape in which a plurality of channels 111 are formed side by side, the adhesive 130 is usually heated by heating. Fire).

이와 같이 접착제(130)의 소성이 완료된 후 주입관(140)을 통하여 채널(111)의 내부를 진공상태로 만들고 그 채널(111)의 내부에 가스 및 수은을 충입한 후 상기 주입관(140)을 봉지(밀폐)하고 전극(150)을 부착하면 평판형 형광램프(100)의 제조가 완료된다. After the calcination of the adhesive 130 is completed, the inside of the channel 111 is made into a vacuum state through the injection tube 140, and gas and mercury are filled in the channel 111, and then the injection tube 140 is filled. After encapsulating (sealing) and attaching the electrode 150, the manufacture of the flat fluorescent lamp 100 is completed.

그러나 이러한 종래의 장치는 상판(110)의 채널(111)에 설치되는 가스 주입관(140)이 상기 채널(111)과 수직한 방향으로 설치되므로 한 개의 기판에 한 개의 상판(110)을 성형하여 평판형 형광램프(100)용 상판(110)을 성형하는 시간이 증가되는 문제점이 있었다. However, in the conventional apparatus, since the gas injection pipe 140 installed in the channel 111 of the upper plate 110 is installed in a direction perpendicular to the channel 111, one upper plate 110 is formed on one substrate. There was a problem that the time for forming the top plate 110 for the flat fluorescent lamp 100 is increased.

본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 하나의 모기판에 복수개의 평판형 형광램프를 형성하여 그 평판형 형광램프의 제조시간을 단축할 수 있는 평판형 형광램프 제조 방법을 제공함에 있다.The present invention is invented to solve the above problems, the object is to form a plurality of flat fluorescent lamps on one mother substrate to reduce the manufacturing time of the flat fluorescent lamp manufacturing method of the flat fluorescent lamp In providing.

상기 목적을 달성하기 위한 본 발명의 특징적인 구성을 설명하면 다음과 같다.Referring to the characteristic configuration of the present invention for achieving the above object is as follows.

본 발명의 평판형 형광램프 제조방법은 복수의 방전채널을 구비하는 평판형 형광램프의 제조방법에 있어서, 하나의 모기판에 상기 방전채널을 구비하는 복수의 단위패널과, 상기 방전채널의 형성 면과 동일 평면상에 형성되면서 상기 방전채널과 통기되는 가스 주입구 및 상기 가스 주입구와 연결되면서 상기 단위 패널들이 공통으로 연결되는 배기관을 포함하는 제 1 기판부재를 형성하는 것과; 상기 제 1 기판부재와 대향하는 평면상에 제 2 기판부재를 합착하는 것과; 상기 방전채널 내의 가스를 배기하는 것과; 상기 방전채널 내에 불활성 가스 및 수은 가스를 주입하는 것과; 상기 방전채널을 밀봉하는 것; 및 상기 모기판을 단위 패널로 절단하는 것을 포함하여서 된 것이다.In the method of manufacturing a flat fluorescent lamp of the present invention, there is provided a method of manufacturing a flat fluorescent lamp having a plurality of discharge channels, comprising: a plurality of unit panels including the discharge channel on one mother substrate, and a surface on which the discharge channel is formed; Forming a first substrate member formed on the same plane as the first substrate member including a gas injection hole through which the discharge channel is vented, and an exhaust pipe connected to the gas injection hole and commonly connected to the unit panels; Adhering a second substrate member on a plane opposite the first substrate member; Exhausting the gas in the discharge channel; Injecting an inert gas and a mercury gas into the discharge channel; Sealing the discharge channel; And cutting the mother substrate into unit panels.

이와 같은 특징을 갖는 본 발명을 상세하게 설명하면 다음과 같다. Referring to the present invention having such characteristics in detail as follows.

도 3은 본 발명에 따른 평판형 형광램프의 분해 사시도이고, 도 4는 본 발명에 따른 평판형 형광램프의 사시도이며, 도 5는 도 4의 가스 주입구 및 수은 게터관의 확대 단면도이고, 도 6은 본 발명에 따른 다른 실시예의 평판형 형광램프의 사시도이다. Figure 3 is an exploded perspective view of a flat fluorescent lamp according to the present invention, Figure 4 is a perspective view of a flat fluorescent lamp according to the present invention, Figure 5 is an enlarged cross-sectional view of the gas inlet and mercury getter tube of Figure 4, Figure 6 Is a perspective view of a flat fluorescent lamp of another embodiment according to the present invention.

먼저, 서로 나란하게 형성된 복수개의 채널(211)이 구비된 평판형 형광램프가 복수개 구비된 제1기판부재(200)를 성형한다.First, the first substrate member 200 having a plurality of flat fluorescent lamps having a plurality of channels 211 formed to be parallel to each other is formed.

상기 제1기판부재(200)를 성형할 때에는 판 형상으로 형성된 유리 재질의 모기판을 가열로의 내부에서 성형 가능온도(T1)로 가열한다. When the first substrate member 200 is molded, a glass substrate formed in a plate shape is heated to a moldable temperature T1 inside the heating furnace.

상기 성형 가능온도(T1)는 650℃ ~ 750℃로 유지하는 것이 바람직하다. 왜냐하면, 650℃이하로 가열할 경우에는 모기판의 변형율이 감소되어 모기판이 불안정하게 성형되고, 750℃이상으로 가열할 경우에는 모기판의 변형율이 증가되어 모기판이 파손되게 된다. The moldable temperature (T1) is preferably maintained at 650 ℃ ~ 750 ℃. Because, when heated to 650 ℃ or less, the strain of the mother substrate is reduced and the mother substrate is unstable, and when heated to 750 ℃ or more, the strain of the mother substrate is increased to damage the mother substrate.

이와 같이 가열된 모기판은 이동수단에 의해서 금형체로 이송된 후 복수개의 단위패널(210)이 성형되는 것이다.The heated mother substrate is transferred to the mold body by the moving means, and then a plurality of unit panels 210 are molded.

이때 상기 모기판에는 각 단위패널(210)에 형성된 채널(211)과 통기되는 가스 주입구(230) 및 상기 가스 주입구(230)와 연결되는 배기관(220)이 상기 채널(211)과 동일 평면상에 형성된다.At this time, the mother substrate has the gas inlet 230 and the exhaust pipe 220 connected to the channel 211 formed in each unit panel 210 on the same plane as the channel 211. Is formed.

한편, 상기 가스 주입구(230)는 도 3 및 도 4에 나타낸 바와 같이 복수개의 단위패널(210)이 서로 통하여지게 구비하거나, 도 5에 나타낸 바와 같이 복수개의 단위패널(210)에 각각 구비하는 것도 가능하다.On the other hand, the gas injection port 230 is provided with a plurality of unit panels 210 through each other, as shown in Figure 3 and 4, or also provided in each of the plurality of unit panels 210 as shown in FIG. It is possible.

상기 제 1 기판부재(200)와 대향하는 평면상에 제 2 기판부재(240)를 합착하되, 이때에는 복수개의 단위패널(210)이 각각 분리되게 제 1 기판부재(200)와 제 2 기판부재(240)의 접촉면에 접착제를 도포하는 것이다.The second substrate member 240 is bonded to a plane facing the first substrate member 200, and in this case, the first substrate member 200 and the second substrate member are separated to separate the plurality of unit panels 210, respectively. The adhesive is applied to the contact surface of 240.

상기와 같이 합착 후 가스 주입구(230)에 밀봉재(260)를 투입하고, 상기 가스 주입구(230)의 일 측에 수은을 함유하는 수은 게터(251)가 내장된 게터관(250)을 끼운다. After the bonding, the sealing material 260 is introduced into the gas inlet 230, and a getter tube 250 having a mercury getter 251 containing mercury is inserted into one side of the gas inlet 230.

상기 배기관(220)을 통해 상기 채널(211) 내부를 배기하여 진공상태로 만들고, 상기 배기관(220)을 통해 비활성 가스를 주입하여 상기 채널(211)을 채운다. The inside of the channel 211 is exhausted through the exhaust pipe 220 to make a vacuum state, and an inert gas is injected through the exhaust pipe 220 to fill the channel 211.

상기 채널(211)이 비활성 가스로 채워지면, 게터관(250)의 수은 게터(251)를 고주파 발생장치등으로 가열하고 수은 증기를 유도하여 수은 증기가 수은 주입구를 통해 방전채널로 확산되게 한다.When the channel 211 is filled with inert gas, the mercury getter 251 of the getter tube 250 is heated by a high frequency generator or the like, and mercury vapor is induced to diffuse mercury vapor into the discharge channel through the mercury inlet.

이어서, 상기 밀봉재(260)를 녹여 채널(211)과 가스 주입구(230) 사이를 차단한다. Subsequently, the sealant 260 is melted to block the channel 211 and the gas injection hole 230.

따라서, 채널(211)은 밀봉재(260)에 의해 완전히 밀폐된다.Thus, channel 211 is completely sealed by sealant 260.

수은이 주입된 채널(211)을 일정온도에서 열처리하여 수은 확산 공정을 진행한다.The mercury-infused channel 211 is heat-treated at a predetermined temperature to proceed with the mercury diffusion process.

가스 주입구(230)와 배기관(220)을 분리함과 동시에 각 단위패널(210)을 분리하는 절단공정을 진행하여 형광램프를 완성한다.The fluorescent lamp is completed by separating the gas inlet 230 and the exhaust pipe 220 and simultaneously separating the unit panels 210.

즉, 본 발명에 의하면, 복수개의 평판형 형광램프를 동시에 제조할 수 있는 것이다.That is, according to the present invention, a plurality of flat fluorescent lamps can be manufactured at the same time.

이와 같이 본 발명 한 개의 모기판에 복수개의 단위패널을 성형하여 복수개의 평판형 형광램프 내부의 진공은 물론 가스 주입 및 수은 확산 공정을 동시에 수행하여 제조할 수 있게 되므로 평판형 형광램프의 제조시간을 단축할 수 있는 특유의 효과가 있다.As such, by forming a plurality of unit panels on one mother substrate of the present invention, it is possible to manufacture not only a vacuum in a plurality of flat fluorescent lamps but also a gas injection and mercury diffusion process simultaneously, thereby manufacturing a flat fluorescent lamp. There is a unique effect that can be shortened.
