Abstract

본 발명은 투사형화상표시장치의 광로조절장치에 관한 것으로, L자형의 변형부의 외부면과 내부면에 신호 전극 및 공통전극을 형성하므로 신호인가시 하부의 바닥면은 고정되고 윗면이 x측상으로 변형하며, 상부는 y축상으로 변형하여 액츄에이트 내부표면에 부착되어 있는 에폭시를 변형시켜 상부 표면이 경사지도록 하여 반사경을 경사지게 한다. 따라서, 변형부내에 전극이 필요하지 않으므로 전극을 쉽게 형성할 수 있어 제조가 간단하며, 구조가 간단하고 제조가 용이하므로 화소의 집적도를 향상시킬 수 있으며, 또한, 양축방향 변형을 이용하므로 광변조 효율을 제고할 수 있다.The present invention relates to an optical path control device of a projection image display device. Since the signal electrode and the common electrode are formed on the outer and inner surfaces of the L-shaped deformation part, the bottom surface of the lower part is fixed and the top surface is deformed on the x side when the signal is applied. The upper part is deformed on the y-axis to deform the epoxy attached to the actuator inner surface so that the upper surface is inclined, thereby inclining the reflector. Therefore, since the electrode is not required in the deformable portion, the electrode can be easily formed, the manufacturing is simple, the structure is simple and the manufacturing is easy, so the integration degree of the pixel can be improved, and the biaxial deformation is used, so the light modulation efficiency Can be improved.
