Abstract

본 발명은 광 효율을 높히기에 적합한 투사형 화상 표시장치의 광로 조절 장치 구조에 관한 것으로, 종래에는 지지부의 면적이 좁기 때문에 거울 전체를 지지하기에는 부적합하며, 그 지지부의 면적을 넓게 할 경우. 거울의 경사지는 면적이 좁아지게 되므로 광 효율이 떨어지는 결점이 있었으나, 본 발명에서는 지지부(10) 사이에 보조 지지부(14)를 헝성하므로써 액츄에이터의 구조가 보다 안정하게 되며, 지지부(10)의 폭을 줄일 수 있으므로 구동시. 경사지는 거울(13)의 면적이 넓어져 광 효율이 증가해서 결국, 화질이 향상되므로 상기 결점을 개선시킬수 있는 것이다.The present invention relates to an optical path adjusting device structure of a projection type image display device suitable for increasing light efficiency, and is conventionally unsuitable for supporting the entire mirror because the area of the support is narrow, and the area of the support is widened. Since the inclined area of the mirror is narrowed, there is a disadvantage that the light efficiency is lowered. However, in the present invention, the structure of the actuator becomes more stable by forming the auxiliary support 14 between the support 10, and the width of the support 10 is increased. When driving so reduce. Since the area of the inclined mirror 13 is increased to increase the light efficiency, and thus, the image quality is improved, the above-mentioned defect can be improved.
