그리고, 상기 관찰창(4)은 상기 본체(2)의 전면에 구비된 개폐도어(6)의 중앙부에 장착된 것으로, 대략 사각형으로 구성된 창틀(8)과, 이 창틀(8)에 상호 소정간격 이격되도록 장착되는 내, 외부글라스(10,12)와, 이 내, 외부글라스(10,12)의 사이에 장착된 히터(14)로 구성된다. 상기 창틀(8)은 그 내부에 단열재(16)가 충진된 것으로, 내주면에는 상기 내, 외부글라스(10,12)가 결합되는 한쌍의 결합홈(18,20)이 형성된다. 상기 내부글라스(10)는 이 창틀(8)의 내측에 형성된 결합홈(18)에 삽입설치되는 것으로, 그 둘레부가 창틀(8)에 밀착되어 본체(2)의 내부와 외부를 차단할 수 있도록 구성된다. 상기 외부글라스(12)는 상기 창틀(8)의 외측에 형성된 결합홈(20)에 삽입결합되어 내부글라스(10)와 소정간격 이격되는 것으로, 이 외부글라스(12)와 창틀(8)의 사이에는 외부공기가 출입하는 통공(24,26)이 형성된다. 이 통공(24,26)은 외부글라스(12)의 상하단이 결합되는 창틀(8)의 상하측 내주면에 각각 형성되어, 외부공기가 이격부(22)로 유출입할 수 있도록 된다. 상기 히터(14)는 내, 외부글라스(10,12)의 사이에 형성된 이격부(22)의 하측에 장착되는 것으로, 이격부(22)내부의 공기를 균일하게 가열할 수 있도록 관찰창(4)의 길이 방향을 따라 연장되는 판형상으로 구성된 플레이트 히터를 이용하는 것이 바람직하다.The observation window 4 is mounted at the center of the opening / closing door 6 provided on the front surface of the main body 2, and has a window frame 8 formed of a substantially rectangular shape and a predetermined interval therebetween. It consists of the inner and outer glass 10, 12 mounted to be spaced apart, and the heater 14 mounted between the inner, outer glass (10, 12). The window frame 8 is filled with a heat insulating material 16 therein, the inner circumferential surface is formed with a pair of coupling grooves 18 and 20 to which the inner and outer glass 10 and 12 are coupled. The inner glass 10 is inserted into and installed in the coupling groove 18 formed inside the window frame 8, and the circumference thereof is in close contact with the window frame 8 to block the inside and the outside of the main body 2. do. The outer glass 12 is inserted into and coupled to the coupling groove 20 formed on the outside of the window frame 8 to be spaced apart from the inner glass 10 by a predetermined distance, between the outer glass 12 and the window frame 8. There are through-holes 24 and 26 through which outside air enters. The through holes 24 and 26 are respectively formed on the upper and lower inner circumferential surfaces of the window frame 8 to which the upper and lower ends of the outer glass 12 are coupled, so that the outside air can flow in and out of the spaced part 22. The heater 14 is mounted below the spaced portion 22 formed between the inner and outer glass 10 and 12, and the observation window 4 to uniformly heat the air inside the spaced portion 22. It is preferable to use a plate heater configured in the shape of a plate extending along the longitudinal direction of.

이와같이 구성된 관찰창(4)은 상기 히터(14)로 이격부(22) 내부의 공기를 가열하면, 가열된 공기는 상승하여 외부글라스(12) 상측의 통공(26)을 통해 외부로배출되며, 이격부(22) 내부의 공기가 배출됨에 따라 발생되는 진공압에 의해, 외부공기가 외부글라스(12) 하측의 통공(24)을 통해 이격부(22)로 유입되며 연속적으로 순환하게 된다. 따라서, 가열된 공기에 의해 내, 외부글라스(10,12)가 일정온도로 가열됨과 동시에, 이격부(22) 내부의 습기가 상기 통공(26)으로 배출되므로, 글라스(10,12)에 성애가 끼거나 김이 서리는 것을 방지할 수 있으며, 글라스(10,12)에 성애가 끼거나 김이 서리더라도, 상기 히터(14)를 작동시켜 성애나 김을 제거할 수 있다.When the observation window 4 configured as described above heats the air inside the separation unit 22 with the heater 14, the heated air rises and is discharged to the outside through the through hole 26 above the outer glass 12. By the vacuum pressure generated as the air inside the spacer 22 is discharged, the outside air is introduced into the spacer 22 through the through-hole 24 under the outer glass 12 and continuously circulated. Therefore, the inner and outer glass 10, 12 is heated to a predetermined temperature by the heated air, and the moisture inside the separation portion 22 is discharged to the through hole 26, so that the glass 10, 12 It is possible to prevent the frost or steam frost, even if the frost or frost on the glass (10,12), it is possible to remove the frost or steam by operating the heater (14).

이상에서와 같이 본 발명에 의하면, 내, 외부글라스의 이중으로 구성된 관찰창의 내부에 히터를 설치하고, 외부글라스의 상하측에 통공을 형성하여, 외부공기가 내부로 순환할 수 있도록 하므로써, LCD 에이징 테스터의 내부온도와 외부온도의 차이에 의해, 관찰창의 글라스 표면에 김서림이나 성애가 발생되는 것을 방지할 수 있도록 된 새로운 구조의 액정디스플레이 내구성 시험장치를 제공할 수 있다.As described above, according to the present invention, by installing a heater inside the observation window consisting of a double of the inner, outer glass, and through the upper and lower sides of the outer glass to allow the outside air to circulate inside, LCD aging Due to the difference between the internal temperature and the external temperature of the tester, it is possible to provide a liquid crystal display durability test apparatus having a new structure that can prevent the occurrence of fog and frost on the glass surface of the observation window.
