이와 같이 홀더(24)에 안착된 도광판(23)이 이탈하지 않도록 하부 케이스(22)를 상부 케이스(21)의 상부에서 하부로 결합시킨다.As such, the lower case 22 is coupled from the upper part of the upper case 21 to the lower part so that the light guide plate 23 seated on the holder 24 does not detach.

이렇게 고정된 상.하부 케이스(21)(22)의 일측에 보호판(212)을 고정시킨 후, 단말기의 상부에 형성된 힌지축(15)에 회전가능하게 고정시키면 플립이 완성된다.The fixing plate 212 is fixed to one side of the upper and lower cases 21 and 22 fixed as described above, and then, when the protection plate 212 is rotatably fixed to the hinge shaft 15 formed at the upper portion of the terminal, the flip is completed.

다음은 상기와 같이 고정된 백라이트 장치의 작동과정을 설명한다.The following describes the operation of the fixed backlight device as described above.

먼저, 제어부재(261)에 전원이 인가되어 제어를 해제하고, 플렉시블 PCB(25)의 제어에 의해 LED 광원(262)에서 빛을 발산하면, 이 빛은 집광판(231)을 통해 집광되어 도광판(23) 전체로 확산되며, 도광판(23)으로 확산된 빛은 확산필름(232)을 통해 동시에 내.외측 LCD(27)(28)로 전달되어 상.하부 케이스(21)(22)에 부착된 보호판(212)을 통해 외부로 발산된다. 이때, 사용자로 하여금 메세지나 기타 기능을 쉽게 확인할 수 있도록 빛을 제공하게 되는 것이다.First, when power is applied to the control member 261 to cancel the control, and the light is emitted from the LED light source 262 by the control of the flexible PCB 25, the light is collected through the light collecting plate 231 and the light guide plate ( 23) The light diffused to the entire light guide plate 23 is transmitted to the inner and outer LCD 27, 28 through the diffusion film 232 and attached to the upper and lower cases 21 and 22 at the same time. The protection plate 212 is emitted to the outside. At this time, the user is provided with a light so that the user can easily check the message or other functions.

이상에서와 같이 본 발명 듀얼 폴더의 백라이트 장치는, 하나의 LED 광원으로 내.외측 LCD를 동시에 발광시키는 백라이트를 사용하여 단말기 제품의 두께를 슬림화시킴과 아울러, 부품을 줄이고 작업공정을 간소화하여 제품의 생산 단가를 낮춤과 동시에 생산력을 증대시켜 경쟁력을 향상시키는 이점이 있는 것이다.As described above, the dual-fold backlight device of the present invention uses a backlight that simultaneously emits an inner and an outer LCD with a single LED light source to reduce the thickness of the terminal product, reduce components, and simplify the work process. It has the advantage of improving the competitiveness by lowering the production cost and increasing the productivity.
