본 발명은 입체영상장치에 관한 것이다. 상세하게는 투명전극의 패턴 형상을 가로줄 패턴형상의 격자 구조로 설계하고, 전기신호를 ON/OFF시켜 3D 패널에서 위상차가 발생되도록 함으로써 TN LCD 기본구조에서 상하 투명판 양쪽 표면의 편광판 2장을 모두 제거한 형태의 편광안경식 3D 패널을 사용한 입체영상장치에 관한 것이다. The present invention relates to a stereoscopic image device. In detail, the pattern shape of the transparent electrode is designed in a horizontal grid pattern structure, and the phase difference is generated in the 3D panel by turning on / off the electric signal so that the two polarizers on both surfaces of the upper and lower transparent plates in the basic structure of the TN LCD are It relates to a three-dimensional imaging device using a polarized glasses 3D panel of the removed form.

입체영상 디스플레이 기술에는 안경방식과 무안경방식이 있다. 안경방식에는 편광방식과 시분할방식이 있고, 무안경 방식에는 패럴랙스 배리어 방식과 렌티큘라 방식이 있다. 편광방식은 1935년 E.H.Land가 편광판을 사용한 입체필름 방식을 발표하여 오늘날 널리 사용되고 있는 편광 필터에 의한 입체표시방식이다. 무안경 방식은 1903년 미국의 F.E.Ives가 패럴랙스 스테레오그램으로 불리는 입체시법을 제안한 후 여러 사람의 연구가 진행되어 오다가, 미국 DTI사와 일본 SHARP사, 국내 폐사가 개발한 패럴랙스 배리어 방식의 퍼스널 컴퓨터용 입체영상 디스플레이 장치가 시판되고 있다. Stereoscopic image display technologies include glasses and glasses-free. There are a polarizing method and a time division method in the glasses method, and there are a parallax barrier method and a lenticular method in the glassesless method. In 1935, E.H.Land announced a three-dimensional film method using a polarizing plate, and is a three-dimensional display method using a polarizing filter widely used today. The glasses-free method was developed in 1903 by the FEIves of the United States, which proposed a stereoscopic method called the parallax stereogram. Stereoscopic image display devices for personal computers are commercially available.

편광안경식 3D 디스플레이관련 종래 기술은 위상지연판 (Retarder)소재를 사용한 방식이 있다. 위상지연판 방식에는400 ~ 1200 미크론의 특수필름(2축 방향 연신방법의 폴리카보네이트, PVA)을 사용하거나 Mesogen(특수액정)을 사용하는데, 이 방식은 유리판 위에 얇은 필름 타입의 위상지연판을 부착한 후, 뜨거운 물이나 초경 칼날등으로 가공하거나, 액정 물질의 일종인 mesogen을 유리판에 도포한 후 여 러 과정을 거쳐서 제작하여 사용한다. 그러나, 2가지 방법 모두 불량률이 높고 생산 가격이 높다는 단점이 있다. 또한, 3D 모니터의 생산시, 위상지연판 소재면이 노출되어 있어서 생산 공정 중에서 표면손상 관리에 매우 주의를 해야 하고, 필름 부착면에서 점착 성분이 노출되어 있어서 생산시 주변 오염 가능성이 높아 생산성이 매우 떨어진다. The related art related to polarizing glasses type 3D display is a method using a phase retarder material. Phase delay plate method uses 400 ~ 1200 micron special film (polycarbonate, PVA in biaxial drawing method) or Mesogen (special liquid crystal), which attaches thin film type phase delay plate on glass plate. After that, it is processed by hot water or cemented carbide blade or by applying mesogen, which is a kind of liquid crystal material, on the glass plate, and it is manufactured and used through various processes. However, both methods have disadvantages of high defect rate and high production price. In addition, when the 3D monitor is produced, the surface of the phase delay plate is exposed, so care must be taken to control the surface damage during the production process, and since the adhesive component is exposed on the film-attached surface, there is a high possibility of surrounding contamination during production. Falls.

도 1은 위상지연판 타입의 편광안경식 3D 원리를 나타내고 있는데, 일반 TFT LCD(10)에 종래의 편광안경식 3D 패널(20)인 박판 필름형 위상지연판 타입의 3D 패널을 부착하여 입체영상을 볼 수 있게 되는데, 3D 패널에 사용되는 소재는 박판 필름, 또는 mesogen을 사용하였으며, 영상 패널(10)의 가로 방향으로 홀수행(L)에는 좌안용의 영상을 표시하고, 짝수행(R)에는 우안용 영상을 표시한 후, 기존의 편광안경식 3D 패널(20)을 영상 패널의 전면에 부착하여, 좌안용 화소로부터 나온 빛은 3D 패널(20)의 위상지연판이 있는 부분(202)을 통과하면서 편광방향이 90도 회전되어 나오게 되고, 우안용 화소로부터 나온 빛은 3D 패널(20)의 위상지연판이 없는 부분(201)을 그대로 통과하게 된다. 이때 관찰자는 좌안용 화소로부터 나온 빛이 3D 패널(20)의 위상지연판이 있는 부분(202)을 통과하면서 편광방향이 90도 회전되어 나온 빛이 통과할 수 있는 편광판을 왼쪽 눈앞에 위치시키고, 우안용 화소로부터 나온 빛이 통과할 수 있는 편광판을 오른쪽 눈앞에 위치시켜서 편광안경(30)으로 관찰하면 입체영상을 볼 수 있게 된다. 1 illustrates a principle of a phase delay plate type polarizing glasses type 3D. A 3D panel of a thin film type phase delay plate type, which is a conventional polarizing glasses type 3D panel 20, is attached to a general TFT LCD 10 to view a stereoscopic image. The material used in the 3D panel was a thin film or mesogen, and the image for the left eye was displayed in the odd row (L) in the horizontal direction of the image panel 10, and the right eye in the even row (R). After displaying the dragon image, the conventional polarized eyeglass type 3D panel 20 is attached to the front of the image panel, and the light from the left eye pixel is polarized while passing through the portion 202 having the phase delay plate of the 3D panel 20. The direction is rotated by 90 degrees, and the light from the right eye pixel passes through the portion 201 without the phase delay plate of the 3D panel 20 as it is. At this time, the observer places the polarizing plate through which the light from the left eye pixel passes through the phase delay plate 202 of the 3D panel 20 and the light from which the light is rotated by 90 degrees is passed in front of the left eye. When the polarizing plate through which the light from the dragon pixel can pass is positioned in front of the right eye and observed with the polarizing glasses 30, a stereoscopic image can be seen.

FIG. 2 is a cross-sectional view of FIG. 1. In the conventional TFT LCD 10, glass 12 and 14 are attached to both sides of a central TFT LCD liquid crystal layer 11, and polarizing plates 13 and 15 are attached to the glass, respectively.

그러나, 기존의 3D 패널에 사용되는 소재가 박판 필름, 또는 mesogen을 사용하고는 있으나, 2가지 방법 모두 불량률이 높고 생산 가격이 높다는 단점이 있다. 또한, 3D 모니터의 생산시 위상지연판 소재면이 노출되어 있어서 생산 공정 중에서 표면손상 관리에 매우 주의를 해야 하고, 필름 부착면에서 점착 성분이 노출되어 있어서 생산시 주변 오염 가능성이 높아 생산성이 매우 떨어지는 문제점이 있다.However, although the material used in the existing 3D panel uses a thin film or mesogen, both methods have a disadvantage of high defect rate and high production price. In addition, the surface of the phase delay plate is exposed during the production of the 3D monitor, so care must be taken to manage the surface damage during the production process, and since the adhesive component is exposed on the film attachment surface, there is a high possibility of surrounding contamination during production, resulting in very low productivity.

The liquid crystal layer 41 is alternately formed to correspond to odd rows and even rows of the panel, and rotates the polarization direction of incident light by 90 degrees between the transparent plates 42 and 43. At this time, it is preferable that a transparent plate is glass.

이에 따라, 좌안용 화소로부터 나온 빛은 3D 패널(40)의 투명전극이 없는 부분(402)을 통과하면서 편광방향이 90도 회전되어 나오게 되고, 우안용 화소로부터 나온 빛은 3D 패널의 투명전극이 있는 부분(401)을 그대로 통과하게 된다. 이때 관찰자는 좌안용 화소로부터 나온 빛이 3D 패널의 투명전극이 없는 부분을 통과하면서 편광방향이 90도 회전되어 나온 빛이 통과할 수 있는 편광판을 왼쪽 눈앞에 위치시키고, 우안용화소로부터 나온 빛이 통과할 수 있는 편광판을 오른쪽 눈앞에 위치시켜서 편광안경(30)으로 관찰하면 입체영상을 볼 수 있게 된다. Accordingly, the light emitted from the left eye pixel is rotated by 90 degrees while passing through the portion 402 of the 3D panel 40 without the transparent electrode, and the light emitted from the right eye pixel is the transparent electrode of the 3D panel. It passes through the portion 401 as it is. At this point, the observer places a polarizer in front of the left eye where light from the left eye pixel passes through the transparent electrode of the 3D panel without the transparent electrode and rotates the polarization direction by 90 degrees. When the polarizing plate that can pass through is positioned in front of the right eye and observed with the polarizing glasses 30, a stereoscopic image can be seen.

도 5를 참조하여 본 발명에 대한 좀 더 상세한 원리를 설명하면, 본 발명의 편광안경식 3D 패널(40)의 구조에서 투명전극이 없는 부분(402)과 투명전극(45,46)이 있는 부분(401)이 형성된다.Referring to FIG. 5, a more detailed principle of the present invention will be described. In the structure of the polarizing glasses 3D panel 40 according to the present invention, a part having no transparent electrode 402 and a part having transparent electrodes 45 and 46 ( 401 is formed.

투명전극이 없는 부분(402)에서는 편광판(15)을 통과한 빛은 투명판(42)을 통과한 후, 액정층(41)을 통과하면서 네마틱 액정들에 의해 편광방향이 90도 회전한 후, 투명판(43)을 통과하여 편광안경(30)의 좌안용 편광판을 통과한 다음 좌안에 이르게 된다.In the portion 402 having no transparent electrode, the light passing through the polarizing plate 15 passes through the transparent plate 42, and then passes through the liquid crystal layer 41, and the polarization direction is rotated 90 degrees by nematic liquid crystals. After passing through the transparent plate 43, passes through the left eye polarizing plate of the polarizing glasses 30, and then reaches the left eye.

한편, 투명전극(45,46)이 있는 부분(401)에서는 편광판(15)을 통과한 빛은 투명판(42)을 통과한 후, 액정층(41)의 전후에 형성된 투명전극 양단에 걸려 있는 전계에 의해서 네마틱 액정들이 정렬되어져서 편광방향이 바뀌지 않은 상태로 액정층(41)을 통과하고, 또 그 다음 투명판(43)을 통과하여 편광안경(30)의 우안용 편광판을 통과하여 우안에 이르게 되어 관찰자는 좌안과 우안에 합당한 서로 다른 영상을 볼 수 있기 때문에 입체감을 느끼게 되는 것이다. 여기에서 편광안경(30)은 좌안과 우안이 편광방향이 서로 90도 차이가 나는 구조로 제작되어 있다. On the other hand, in the portion 401 having the transparent electrodes 45 and 46, the light passing through the polarizing plate 15 passes through the transparent plate 42, and then hangs at both ends of the transparent electrode formed before and after the liquid crystal layer 41. The nematic liquid crystals are aligned by the electric field to pass through the liquid crystal layer 41 without changing the polarization direction, and then through the transparent plate 43 to pass through the right eye polarizing plate of the polarizing glasses 30 and to the right eye. As a result, the observer can feel a three-dimensional effect because the viewer can see different images appropriate to the left eye and the right eye. Here, the polarizing glasses 30 are manufactured in a structure in which the left and right eyes differ in polarization directions from each other by 90 degrees.

이상 본 발명을 상기 실시예를 들어 설명하였으나, 본 발명은 이에 제한되는 것이 아니다. 당 업자라면 본 발명의 기술사상의 범위를 벗어나지 않고 수정, 변경 등이 가능하며 이러한 수정과 변경 또한 본 발명에 속하는 것임을 알 수 있을 것이다. Although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto. Those skilled in the art will appreciate that modifications, changes, and the like can be made without departing from the scope of the technical idea of the present invention, and such modifications and changes also belong to the present invention.

본 발명에 의하면, 3D 패널의 투명전극이 있는 부분에 전기신호를 인가하고 편광안경을 착용하면 입체 영상을 볼 수 있고, 전기신호를 OFF하고 편광안경을 벗으면 일반영상을 볼 수 있는 2D/3D 겸용 편광안경식 입체영상 표시장치로 사용할 수 있는 장점이 있다.  According to the present invention, when the electric signal is applied to the transparent electrode portion of the 3D panel and the polarized glasses are worn, the stereoscopic image can be viewed, and the electric signal is turned off and the polarized glasses are taken off. There is an advantage that can be used as a polarized glasses stereoscopic display device.

또한, TN LCD 구조의 패턴 형상 격자 구조가 가로줄 패턴 형상이고, TN LCD 기본 구조에서 양쪽의 편광판 2장 모두가 제거되어 가격이 저렴해지는 장점이 있다. In addition, the grid pattern structure of the TN LCD structure has a horizontal line pattern shape, and the two polarizers on both sides of the TN LCD basic structure are removed, thereby reducing the price.

또한, 패널에 형성된 액정층이 2장의 투명판 사이에 있고 양쪽 표면이 투명면이기 때문에 오염이나 클리닝에 문제가 없어서 불량률이 낮고 작업성을 향상시키는 효과가 있다. In addition, since the liquid crystal layer formed on the panel is between two transparent plates and both surfaces are transparent surfaces, there is no problem of contamination or cleaning, so that the defective rate is low and the workability is improved.
