본 발명은 자동차에 설치된 액정 디스플레이장치의 각도조절에 관한 것으로, 특히 운전자나 또는 조수석에 탑승한 탑승자의 시선위치에 따라 디스플레이장치의 각도를 자동으로 조절하여 시인성을 향상시키기 위한 디스플레이 각도 조절장치에 관한 것이다.The present invention relates to an angle adjustment of a liquid crystal display device installed in an automobile, and more particularly, to a display angle adjusting device for improving visibility by automatically adjusting the angle of the display device according to the driver's or passenger's occupant's gaze position. will be.
일반적으로 LCD(Liquid Crystal Display)는 투명 전극막을 붙인 2장의 유리판 사이에 액정이 삽입된 겹층구조의 디스플레이 패널이다. 액정은 유동성을 갖는 액체와 분자가 규칙적으로 배열하는 결정과의 중간 상태를 가지는 물질로 양자의 성질을 함께 갖추고 있다. 액정은 길고 가느다란 막대기 모양의 분자 구조를 갖는 유기 화합물로서 광학적 굴절률과 유도전류율에 이방성을 나타낸다. 액정으로 외부에서 전계를 인가하면 액정의 유동성과 유도전류율 이방성에 의해서 분자 배열이 변화되어 굴절률 이방성에 의해 선광성과 광산란 등의 광학적 성질을 변화한다.In general, an LCD (Liquid Crystal Display) is a layered display panel in which a liquid crystal is inserted between two glass plates attached with a transparent electrode film. Liquid crystal is a substance having an intermediate state between a liquid having fluidity and a crystal in which molecules are regularly arranged, and have both properties. Liquid crystal is an organic compound having a long, thin rod-shaped molecular structure, and exhibits anisotropy in optical refractive index and induced current rate. When an external electric field is applied to the liquid crystal, the molecular arrangement is changed by the liquidity and the induced current rate anisotropy of the liquid crystal, and the optical properties such as opticality and light scattering are changed by the refractive anisotropy.
LCD는 자발광형 디스플레이 장치가 아니기 때문에 내장치수가 CRT와 비교해서 얇은 판 모양으로 구성할 수 있다는 점에서 자동차용으로 실용화되고 있다.Since the LCD is not a self-luminous display device, it has been put to practical use in automobiles in that the number of internal devices can be configured in a thin plate shape compared to the CRT.
그러나 LCD표시장치는 유리와 수직방향으로 편광된 빛이 투과되기 때문에 투시각도에 따라 시인성이 크게 변하는 단점이 있다. 즉, LCD모니터에서 재현되는 화상은 일정한 투과 각도를 가지고 있고, 또한 LCD모니터가 일정 위치로 고정되어 있기 때문에 운전자의 체형이나 운전자세에 따라 화상데이터가 잘 보이지 않는 문제점이 있으며, 특히 주간에는 자연광에 의해 시인성 정도가 더욱 약화되는 현상을 보이고 있다.However, LCD displays have a disadvantage in that visibility is greatly changed according to the viewing angle because light polarized in the vertical direction with glass is transmitted. That is, the image reproduced on the LCD monitor has a certain transmission angle, and since the LCD monitor is fixed at a certain position, there is a problem that the image data is not easily seen according to the driver's body type or driver's posture. As a result, the degree of visibility is further weakened.
본 발명은 이러한 문제점을 해결하기 위해 안출된 것으로, 특히 운전자의 체형이나 또는 운전자세에 따라 LCD모니터 위치를 최적 각도로 회전시켜 화상데이터가 운전자에게 잘 전달되도록 하는 디스플레이 각도 조절장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and in particular, to provide a display angle adjustment device for transmitting the image data well to the driver by rotating the LCD monitor position at an optimum angle according to the driver's body shape or driver's posture. There is this.

이하, 상기한 바와 같은 본 발명에 의한 디스플레이 각도 조절장치의 작용 및 효과를 설명한다.Hereinafter, the operation and effects of the display angle adjusting device according to the present invention as described above.
본 발명은 상술한 바와 같이 운전자의 착석위치에 따라 LCD모니터(110) 각도를 조절하여 운전자에게 최적의 시인성을 확보할 수 있도록 하기 위한 것으로, 운전자가 차량에 탑승하여 시트에 착석하게 되면 CCD카메라(120)는 운전자의 머리부분의 영상을 화상처리부(130)에 인가하게 된다. 이와 같이 운전자의 머리부분에 대한 영상데이터가 화상처리부(130)에서 처리되어 마이컴(140)에 인가되면, 상기 마이컴(140)은 입력된 머리부분 영상데이터를 XY좌표에 클로즈업시켜 운전자의 눈높이를 파악하게 되고 아울러 LCD모니터(110) 각도가 저장된 이전 데이터를 근거로 각도조절모터(150)에 각도조절신호를 인가함으로써 상기 LCD모니터(110)의 상·하 각도를 운전자의 눈과 일직선에 위치하도록 조절함과 동시에 좌·우 각도를 조절하여 운전자 방향으로 조절하게 된다.The present invention is to ensure the optimum visibility to the driver by adjusting the angle of the LCD monitor 110 according to the seating position of the driver as described above, when the driver is seated in the vehicle seated on the CCD camera ( 120 applies an image of the driver's head to the image processor 130. As such, when the image data of the driver's head is processed by the image processor 130 and applied to the microcomputer 140, the microcomputer 140 closes the input head image data to the XY coordinates to determine the driver's eye level. In addition, by applying an angle adjustment signal to the angle adjustment motor 150 on the basis of the previous data stored angle of the LCD monitor 110 to adjust the upper and lower angles of the LCD monitor 110 to be in line with the driver's eyes. At the same time, it adjusts the left and right angles to the driver's direction.
따라서 LCD모니터(110)의 특성인 일정한 투과 각도에 의해 사면에서 바라볼 경우 화상데이터가 잘 보이지 않는 것을 상기 LCD모니터(110)의 상·하·좌·우 각도를 조절하여 운전자의 시야의 직선으로 일치시킴으로써 최적의 시인성을 확보할 수 있게 된다.Therefore, the image data is hard to see when viewed from a slope by a constant transmission angle, which is a characteristic of the LCD monitor 110, by adjusting the up, down, left, and right angles of the LCD monitor 110 to a straight line of the driver's field of view. By matching, optimum visibility can be ensured.
한편, 본 발명은 운전석뿐만 아니라 조수석에서도 LCD모니터(110)의 화상데이터를 시인할 수 있도록 모드선택스위치(160)에 의해 모드를 선택할 수 있으며, 상기 LCD모니터(110)의 각도조절은 상기한 방법과 동일하다.On the other hand, the present invention can select the mode by the mode selection switch 160 to visually recognize the image data of the LCD monitor 110, as well as the driver's seat, the angle adjustment of the LCD monitor 110 is the method described above Is the same as
이상에서 설명한 바와 같이, 본 발명에 의한 디스플레이 각도 조절장치는 운전자의 위치나 또는 착석자세에 따라 변화하는 눈의 위치를 파악하여 마이컴에서 LCD모니터를 운전자의 눈높이와 최적 상태로 각도를 조절함으로써 LCD의 고유 투과 각도에 따른 시인성의 불량을 개선할 수 있는 효과가 있다.As described above, the display angle adjusting device according to the present invention detects the position of the eye that changes according to the driver's position or the seating posture and adjusts the LCD monitor in the microcomputer to the driver's eye level and optimal state by controlling the angle of the LCD. There is an effect that can improve the poor visibility according to the inherent transmission angle.
