Abstract: A method for electrically connecting a thin film electrode to a connecting terminal on an active matrix in the manufacture of a thin film actuated mirror is disclosed. The method includes the steps of: forming a thin film sacrificial layer having an empty cavity on top of the active matrix; forming an elastic, a second thin film and a thin film electrodisplacive layers, successively, on top of the thin film sacrificial layer including the empty cavity; forming a contact hole extending from top of the thin film electrodisplacive layer to top of the connecting terminal; forming a first thin film layer on top of the thin film electrodisplacive layer including the contact hole; patterning the first thin film, the thin film electrodisplacive, the second thin film and the elastic layers, respectively; and removing the thin film sacrificial layer, thereby forming the thin film actuated mirror.

Abstract: The thin film AMA has a substrate, an actuator, a common line, and a reflecting member. The substrate has an electrical wiring and a connecting terminal and the actuator has a supporting layer, a bottom electrode, a top electrode, and an active layer. The common line is formed on a portion of actuator and is connected to top electrode. The electrical wiring and connecting terminal may not be damaged because actuator is formed on a portion of substrate adjacent to the portion where electrical wiring and connecting terminal are formed. The voltage drop of a second signal can be minimized because common line is formed thickly on a portion of actuator, so a sufficient second signal is applied to top electrode. The flatness of reflecting member may be enhanced because reflecting member is formed on a second sacrificial layer.

Abstract: A method for electrically connecting a thin film electrode with a connecting terminal on an active matrix in a thin film actuated mirror includes the steps of: forming a thin film sacrificial layer having an empty cavity on top of the active matrix, wherein the empty cavity encompasses the connecting terminal; forming an elastic layer on top of the thin film sacrificial layer including the empty cavity; creating a hole on the elastic layer, the hole exposing the connecting terminal and having inner surfaces; forming the thin film electrode on top of the elastic layer including the inner surfaces of the hole to thereby establish an electrical connection between the thin film electrode to the connecting terminal; and filling the hole with an insulating material. The insulating material prevents the thin film electrodes in each of the thin film actuated mirrors from coming into an electrical contact with each other, thereby preventing a short-circuit therebetween.

Abstract: A character information processing circuit performs half-blanking by decreasing the gain of a video signal component representing a background screen when various OSD characters, such as a menu, are to be displayed on the screen. Reducing the gain of the background screen enables the OSD characters to be easily distinguished. It should be noted that the background screen is also visible in the region where OSD characters are displayed due to adjustment of the blanking amount of the video signal in the OSD region. The character information processing circuit permits adjustment of the screen state produced in the OSD region by an OSD circuit. A method for generating an optimal OSD display is also described.
