PROJECTION LENS UNIT FOR KEYSTONE/TILT CORRECTION, AND METHOD FOR REMOTELY CORRECTING KEYSTONE/TILT USING IT

摘要

The invention Keystone / tilt correction Keystone / tilt remote calibration method using a projection lens unit and for him relates to, and a projection lens for projecting an image on a screen made of a portion of the optical engine constituting the projection type image display device; And a base provided on one side of the housing for receiving the projection lens; Via a joint to the outer corner points of the base portion 4 rotatably connected to the threaded portion and the post being formed by a predetermined depth along the axis; And motor mounting plate fixed to one side of the base and the separating optical engine having a front end and a corresponding threaded portion formed on an outer peripheral surface corresponding to the threaded portion of the respective posts; Each motor is electrically connected and is characterized in that the adjustment element made to control the angle of the projection lens via the motor. Thus, the present invention makes it possible to be able to adjust the projection lens of an optical engine that is applied to a projection TV or a projector using the motor more easily correct the keystone / tilt of the optical engine.
