摘要： The present invention relates to a three-dimensional filter for realizing a three-dimensional image using one office or home projector without a dark time or delay time setting function. Provided is a three-dimensional digital filter which compensates the delay time of a liquid crystal panel functioning as a filter with an electric circuit to execute a driving signal in advance as long as the delay time at the last part or the start part of an image frame; to set an action potential difference at a very high level by applying a high voltage more than or equal to 24V as an applied voltage to accelerate the response speed of the liquid crystal panel; to include a circuit for adjusting each of positive (+) low voltages and negative (-) low voltages of a main action liquid crystal panel and a compensating liquid crystal panel to compensate errors of a low applied voltage slightly differently operating by panel; to install the main action liquid crystal panel and the compensating liquid crystal panel to make the optical properties of the liquid crystal panels perpendicular, in order to overcome a difference between an image state when a left image is converted into a right image and an image state when the right image is converted into the left image, wherein the difference of the image states is generated by difference in action properties when a voltage is applied to the liquid crystal panel and the voltage is removed from the liquid crystal panel; and to accurately match converted states between the left image and the right image due to the application and removal of the voltage by forming opposite voltage application states in the images. Accordingly, the three-dimensional digital filter of the present invention realizes high quality three-dimensional images using one cost effective office or home projector, thereby attributing to the development of a three-dimensional image industry and saving costs required for managing and maintaining a three-dimensional image facility when the facility is established.
