ABSTRACT:
Thin film AMA in an optical projection system and a method for manufacturing the same are disclosed. The thin film AMA has a substrate having an electrical wiring and a connecting terminal, a supporting element formed on the substrate, an actuator formed on the supporting element, and a reflecting member formed on the actuator. The actuator has a maximum length in order to have a large tilting angle, so the reflecting member installed on the actuator has a large tilting angle. Hence, the light efficiency of the light reflected by the reflecting member increases and the contrast of the picture projected onto a screen also increases. As a result, the quality of the picture is enhanced. Furthermore, the distance between a light source and the screen is wider because the actuator has the large tilting angle.
