Abstract: A method for forming an ultra-low density three-dimensional thin film structure made of a solid thin film, including: radiating ultraviolet rays of different patterns in respective predetermined directions to a liquid photosensitive resin bulk so as to harden a portion of the resin bulk; removing the liquid photosensitive resin which is not hardened so as to form a solid photosensitive resin structure; coating the surface of the solid photosensitive resin structure with a thin film; removing the thin film from the outermost surface of the resin bulk so as to expose the solid photosensitive resin; and removing the solid photosensitive resin structure.

Abstract: An apparatus for operating an AVN (Audio, Video and Navigation) monitor for a vehicle may include a belt guider which is installed in an accommodation space of a dashboard and around which a belt, moving in a longitudinal direction of the belt guider, is wound, a guide rail fixed to the belt guider and extending in the longitudinal direction of the belt guider, a monitor hinge connected to the belt and engaged to the guide rail and an end of a connection bracket so as to move along the guide rail, wherein the connection bracket is connected to the AVN monitor, and a driving force transmission gear engaged with the belt to move the belt in the longitudinal direction.
