Description

디스플레이장치{DISPLAY APPARATUS}Display device {DISPLAY APPARATUS}

본 고안은 디스플레이장치에 관한 것으로, 더욱 상세하게는 연성인쇄회로(FPC)의 보호구조를 갖는 디스플레이장치에 관한 것이다.The present invention relates to a display device, and more particularly to a display device having a protective structure of a flexible printed circuit (FPC).

디스플레이장치란 TV나 컴퓨터용 모니터 등을 통틀어 일컫는 말로서, 크게 CRT모니터, LCD모니터, PDP모니터 등으로 분류된다.A display device is a general term for a TV, a computer monitor, and the like, and is classified into a CRT monitor, an LCD monitor, a PDP monitor, and the like.

근래에 들어 대형화가 용이하고, 화상부의 면적에 비해 그 두께를 얇게 유지할 수 있는 LCD(Liquid Crystal Display) 및 PDP(Plasma Display Panel)와 같은 화상표시패널을 사용한 박막형 디스플레이장치가 많이 사용되고 있다.In recent years, a thin film type display apparatus using an image display panel such as LCD (Liquid Crystal Display) and PDP (Plasma Display Panel), which can be easily enlarged and keep its thickness thin compared to the area of the image part, has been used.

LCD는 표면에 투명전극을 형성한 2장의 유리기판 사이에 액정을 주입한 것으로, 외부로부터 전계를 가해 액정을 회전시켜 빛을 통과시키거나 차단시키는 셔터기능에 의해 화상을 구현한다. 그 중 TFT(Thin Film Transistor) LCD는 액티브(Active) 소자인 스위칭 트랜지스터(Switching Transistor)가 TFT 인 것으로, TFT가 각 픽셀마다 On/Off를 직접 제어하는 방식이다. 각 픽셀마다 독립적으로 On/Off가 제어되므로, 고화질의 영상을 구현할 수 있다.LCD injects liquid crystal between two glass substrates having transparent electrodes formed on the surface. The LCD realizes an image by a shutter function that rotates the liquid crystal by applying an electric field from the outside and passes or blocks the light. Among them, TFT (Thin Film Transistor) LCD is a switching transistor which is an active element, which is a TFT, and a TFT directly controls on / off for each pixel. Since each pixel is independently controlled on and off, it is possible to realize a high quality image.

이하에서는 LCD 방식의 디스플레이장치를 예로 들어 설명한다.Hereinafter, an LCD display device will be described as an example.

종래의 디스플레이장치는 박막트랜지스터기판 및 박막트랜지스터기판의 전면에 마련되는 컬러필터기판을 갖는 액정패널과, 박막트랜지스터기판의 배면 및 컬러필터기판의 전면에 각각 부착되는 편광판을 갖는다. 디스플레이장치는 박막트랜지스터기판의 전면 일측에 실장되어 액정패널을 구동하는 구동회로와, 박막트랜지스터기판의 전면 일측에 결합되어 신호정보를 구동회로에 전달하는 연성인쇄회로를 포함한다. 그리고 액정패널의 후방에 프레임샤시가 결합되어 액정패널을 보호한다.The conventional display apparatus has a liquid crystal panel having a thin film transistor substrate and a color filter substrate provided on the front surface of the thin film transistor substrate, and a polarizing plate attached to the rear surface of the thin film transistor substrate and the front surface of the color filter substrate, respectively. The display apparatus includes a driving circuit mounted on one side of the front surface of the thin film transistor substrate and driving the liquid crystal panel, and a flexible printed circuit coupled to one side of the front surface of the thin film transistor substrate and transmitting signal information to the driving circuit. The frame chassis is coupled to the rear of the liquid crystal panel to protect the liquid crystal panel.

이러한 종래의 디스플레이장치에 있어서, 연성인쇄회로기판과 구동회로간의결합상태를 확인하기 위해 프레임샤시의 일측에는 절개되어 형성되는 절개부가 마련된다. 이 경우 디스플레이장치의 제조과정에서 절개부를 통해 배면으로 연성인쇄회로의 일부가 노출되므로 이물질이 투입되거나 연성인쇄회로가 분리되는 문제가 있다.In such a conventional display device, a cutout formed by being cut is provided at one side of the frame chassis to check the coupling state between the flexible printed circuit board and the driving circuit. In this case, since a part of the flexible printed circuit is exposed to the back through the cutout in the manufacturing process of the display device, foreign matter is introduced or the flexible printed circuit is separated.

본 고안의 목적은, 연성인쇄회로의 보호구조를 갖는 디스플레이장치를 제공하는 것이다.An object of the present invention is to provide a display device having a protective structure of a flexible printed circuit.
