Abstract: 본 발명은 직하타입의 액정표시장치에 관한 것으로, 프레임의 내측면에는 빛을 한방향으로만 반사시키는 경면 반사막을 형성하고, 램프 유닛의 하부면에 설치되는 반사판에는 빛을 확산시켜 반사하는 확산 반사막을 형성하여 빛의 이용효율 및 빛의 균일성을 향상시킨다.
이에 더하여, 경면 반사막이 형성된 프레임의 내측면에 170°정도의 각을 이루도록 제 1 경사면과 제 2 경사면을 형성하여 경면 반사막에서 반사된 빛을 액정표시장치의 화면표시영역의 내부로 유입되도록 유도함으로써 액정표시장치의 가장자리로 좀더 많은 빛이 입사될 수 있다.

Abstract: PURPOSE: A method for removing a blocking artifact included in an image encoded by BDCT(Block Discrete Cosine Transform) is provided to effectively reproduce a received image by removing the blocking artifact without deleting the edge of the received image and to reduce the quantity of calculations for removing the blocking artifact to process the received image in real time. CONSTITUTION: An image encoded by BDCT is received. The frequency characteristic of the received image is measured. The received image is moved by at least one pixel in column and row directions, and the frequency characteristic of the moved image is measured. When the difference between the frequency characteristic of the received image and the frequency characteristic of the moved image exceeds a predetermined range, a high-frequency component of the image is removed.

Abstract: PURPOSE: A direct type liquid crystal display and method for assembling the same are to obtain more slimmed LCD and decrease weight of the LCD. CONSTITUTION: A reflection plate(130) is received within the first receiving space of a bottom chassis(110). A connection bar(140) connects the reflection plates separated into multiple pieces to each other. A lamp unit(150) is arranged on the reflection plate and emits the light. A diffusion plate(170) is arranged apart from and over the lamp unit to diffuse the light input from the lamp unit. A mold frame(180) having a square opening(184) is mounted on a coupling portion(120) of the bottom chassis and is coupled to the bottom chassis. An LCD panel(190) is received within the mold frame and displays information through the square opening of the mold frame. A top chassis(200) covers the mold frame to support the LCD panel and is coupled to the bottom chassis.
