Description

소형 디스플레이 패널에 3차원 영상의 구현방법{A Method of displaying 3-D image on small size display panels }A method of displaying 3-D image on small size display panels

현재의 휴대폰과 핸드 PC(Hand PC)는 표시장치로 수동형인 액정 패널과 능동형의 유기발광 다이오드 배열(OLED Array: Organic Light Emitting Diode Array)을 이용하며, 또한 핸드 PC의 경우는 터치패널(Touch Panel)의 기능이 패널 표면에 부착되기 때문에 이들을 이용하여 평면영상과 3차원 영상의 호환이 가능한 기능의 구현은 아주 어려운 문제 중의 하나이다. 일반적으로 안경을 쓰지 않는 무안경식 3차원 영상의 구현은 폭(Pitch)이 일정한 원통형 렌즈가 수평으로 배열된 렌티큘라(Lenticular) 쉬트나 일정 간격으로 슬릿형의 개구가 평행으로 배열된 시차장벽(Parallax Barrier) 쉬트와 같은 특성을 가진 광학 쉬트(Optical Sheet)이 표시패널의 뒤쪽이나 앞쪽에 부착되어 시역(Viewing Zone)의 형성을 위해 사용된다. 그러나 이들 광학 쉬트를 표시패널의 뒤쪽에 부착하는 경우는 액정패널과 같은 수동형의 표시장치에서만 가능하고 유기발광 다이오드 배열에는 부착이 불가능하여 반드시 앞쪽에 부착해야 한다. 앞쪽에 부착하는 경우는 액정과 같은 능동형의 광학 쉬트를 이용할 수도 있으나, 이 액정패널의 존재는 밝기의 감쇄는 물론 기본 원가의 상승으로 이어지며, 또한 터치패널의 부착이 아주 힘들어 진다.Current mobile phones and hand PCs use passive liquid crystal panels and active organic light emitting diode arrays (OLEDs) as display devices, and touch panels in the case of hand PCs. Since the function of) is attached to the surface of the panel, it is one of the very difficult problems to implement a function that is compatible with the planar image and the 3D image by using them. In general, glasses-free three-dimensional images are implemented in a lenticular sheet in which cylindrical lenses having a constant pitch are arranged horizontally, or in a parallax barrier in which slit-shaped openings are arranged in parallel at regular intervals. An optical sheet having the same characteristics as a sheet is attached to the back or front of the display panel and used to form a viewing zone. However, the optical sheets may be attached to the back of the display panel only in a passive display device such as a liquid crystal panel, and may not be attached to the organic light emitting diode array. In the case of attaching to the front side, an active optical sheet such as liquid crystal may be used, but the presence of the liquid crystal panel leads to a decrease in brightness as well as an increase in basic costs, and also makes it difficult to attach the touch panel.

유기발광 다이오드 배열을 표시패널로 사용하는 경우는 이 표시패널을 조명원(Illumination Source)으로 사용하고 액정패널을 표시패널로 사용할 수도 있으나, 밝기의 감쇄는 피할 수가 없고 터치패널의 부착 어려움은 그대로 남는다. 이들의 문제점을 극복하고 간단히 평면영상과 3차원 영상의 호환이 가능한 핸드폰과 핸드 PC를 구현하는 방법 중의 하나는 이들 핸드폰과 핸드 PC의 표시패널 표면과 분리된 광학 쉬트를 핸드폰과 핸드 PC의 가장자리에다 부착시켜, 이 들의 표시패널 표면을 보호하는 덮개(Cover Plate)의 역할을 동시에 할 수 있도록 하는 것일 것이다.In the case of using an organic light emitting diode array as a display panel, the display panel can be used as an illumination source and a liquid crystal panel can be used as a display panel. However, deterioration of brightness is inevitable and the difficulty of attaching the touch panel remains. . One of the ways to overcome these problems and to realize mobile phones and hand PCs that are compatible with planar images and 3D images is to attach optical sheets separated from the display panel surface of these mobile phones and hand PCs to the edges of mobile phones and hand PCs. By attaching it, the cover plate may protect the surface of the display panel.

본 발명은 평면영상과 3차원 영상의 호환이 가능한 핸드폰(Hand Phone)과 핸드 PC(Hand Held Personnel Computer)를 구현하는 방법으로 광학 쉬트를 휴대폰과 핸드 PC의 본체에 고정시키데, 표시패널과는 분리시켜, 3차원 영상의 표시시만 표시패널의 표면에 부착시켜 사용하고 그 나머지 시간에는 표시패널의 표면 보호 덮개로 사용할 수 있게 하는 2차원 과 3차원 호환이 가능한 휴대폰과 핸드 PC용 3차원 영상표시방식에 관한 것이다.The present invention is to fix the optical sheet to the body of the mobile phone and the hand PC by implementing a hand phone (Hand Phone) and a hand PC (Hand Held Personnel Computer) compatible with the planar image and the three-dimensional image, and the display panel 3D image for mobile phones and hand PCs compatible with 2D and 3D which can be separated and attached to the surface of the display panel only when displaying a 3D image and used as a protective cover for the display panel for the rest of the time. It relates to a display method.
