<P>PROBLEM TO BE SOLVED: To prevent the occurrence of vibration when a control input is a pulse, and to reduce vibrations to reduce noise in a projection TV. <P>SOLUTION: The present invention relates to a dynamic aperture for controlling the intensity of light of a projection lens, more particularly to a dynamic aperture driving apparatus and a method for reducing vibration thereof with which vibrations are minimized in spite of a command for sudden location change. The dynamic aperture driving apparatus comprises a rotating means, a driving means, a sensing means, and a driving control means, whereas a location control signal minimizes vibration when the rotating means arrives at a commanded location by an increase in rising time and falling time of a target location signal through an RC integral circuit 610 within the driving control means. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
