Abstract

본 발명은, 투사형 화상 표시장치의 광로조절 수단에 관한 것으로, 능동 매트릭스 기판(31), 도선 패턴(36), 신호전극(32), 공통 접지 전극(33), 제 1 및 제 2 변형부(38)(39), 제 1 및 제 2 구동전달부(40)(41) 및 반사경(34)를 포함한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical path adjusting means of a projection type image display apparatus, wherein the active matrix substrate 31, the conductive pattern 36, the signal electrode 32, the common ground electrode 33, the first and second deformable portions ( 38) 39, first and second drive transmission parts 40 and 41, and a reflector 34.

특히, 본 발명의 바람직한 실시예는, 제 1 및 제 2 변형부(38) 및 (39)간에 소정의 이격간격(T)을 연질의 에폭시로 이루어지는 제 2 구동전달부(41)가 삽입하여 유지하여 형성하고 그 상부에 경질의 에폭시로 이루어지는 제 1 구동전달부(40)가 형성되어 반사경(34)을 유지시켜, 신호 전극층(32)에 응력을 미세하게 미치게하여 액츄에이터의 수명을 연장시켰으며, 또한, 액츄에이터의 휩 변위를 이용하여 반사경(34)을 회전하는 것이 아니라 인가전압 및 전계 세기에 의해 제 1 및 제 2 변형부(38)(39)를 수축 및 팽창하여 그 변위를 이용하여 광로를 조절하므로써 생산성을 보다 향상시킨 것이다.In particular, in the preferred embodiment of the present invention, the second drive transmission portion 41 made of soft epoxy is inserted and held at a predetermined spacing T between the first and second deformable portions 38 and 39. And a first drive transmission portion 40 made of a hard epoxy is formed on the upper portion thereof to maintain the reflecting mirror 34 to extend the life of the actuator by slightly exerting the stress on the signal electrode layer 32. In addition, instead of rotating the reflector 34 using the whip displacement of the actuator, the first and second deformable portions 38 and 39 are contracted and expanded by the applied voltage and the electric field strength, and the optical path is used by the displacement. By adjusting, the productivity is further improved.
