Denoted at 51 is a flexible printed circuit board (FPCB) electrode, and denoted at 52 is an insulating film of a flexible printed circuit board. Polyimide, PET (Polyester), glass epoxy, and the like are usually used. Reference numeral 110 denotes a seal material for sealing the upper plastic substrate and the lower flexible printed circuit board.

도 2과 도 3에서 볼 수 있는 것처럼, 연성인쇄회로기판(FPCB)을 디스플레이의 하판 공통기판으로 사용하면서 그 위에 구동에 필요한 드라이버 IC(스캐닝 드라이버 IC, 데이터 드라이버 IC)(11)(4)와 구동 컨트롤러(7)까지 바로 실장함으로써 멀티 디스플레이 장치의 제조공정을 단순화시킬 수 있다.As shown in Figs. 2 and 3, a flexible printed circuit board (FPCB) is used as a lower common board of the display, and driver ICs (scanning driver ICs, data driver ICs) 11 (4) necessary for driving thereon and By directly mounting the drive controller 7, the manufacturing process of the multi display device can be simplified.

도 4는 본 발명의 활용성을 나타내는 도면이다.4 is a view showing the utility of the present invention.

본 발명은 상측 기판과 하측 기판을 모두 유연성 있는 기판을 사용함으로써 도 4와같이 휘거나 필요에 따라 경계면을 따라 접을 수 있다. 본 발명의 도면에서는 본 발명의 하나의 적용예로서 3 in 1 형태의 플렉서블 멀티 디스플레이 장치를 나타냈지만 궁극적으로는 n x m(가로 m개, 세로 n개)의 메트릭스 형태의 멀티 디스플레이에 적용도 가능하다.According to the present invention, both the upper substrate and the lower substrate can be bent as shown in FIG. 4 by using a flexible substrate or folded along an interface as necessary. In the drawings of the present invention, a 3 in 1 type flexible multi display device is shown as one application example of the present invention, but ultimately, the present invention may also be applied to a multi display having a matrix form of n x m (m horizontal and n vertical).

이상에서 기술한 바와 같이, 본 발명은 두 개 이상으로 구성된 멀티 디스플레이 시스템에서 연성인쇄회로기판(FPCB)을 디스플레이의 공통 하부기판으로 사용하여 각각의 패널을 서로 연결시켜 일체형으로 제작함으로써 제조공정을 단순화시켜 제조 Cost를 절감하는 효과가 있다. 또한 멀티 디스플레이임에도 불구하고 하부기판을 공통으로 사용함으로써 스캐닝 드라이버를 라인별로 하나씩만 사용해도 되기 때문에 복수 개의 패널을 별도로 제작하여 타일형태 붙이는 기존의 멀티 디스플레이 장치에 비해 재료비를 줄이는 효과가 있다. As described above, the present invention simplifies the manufacturing process by using a flexible printed circuit board (FPCB) as a common lower substrate of the display in the two or more multi-display system by connecting the panels together and fabricating them in one piece. This reduces the manufacturing cost. In addition, despite using a multi-display, since the lower substrate is used in common, only one scanning driver may be used for each line, thereby reducing the material cost compared to a conventional multi-display apparatus in which a plurality of panels are separately manufactured and attached.
