Abstract
An image display apparatus including a liquid crystal display panel (LCD) constituting an image display plane composed of a plurality of pixels arranged with a pixel pitch, a LCD driver circuit which receives an input image signal S,and displays an image on a substantially whole image display plane of the LCD as well as a part of the image on a selected region C of the image display plane by selectively shifting image display positions of the image with respect to inherent positions on said image display plane in a given direction by an integer multiple or an inverse of an integer multiple of the pixel pitch of the LCD, and a pixel shift driver circuit which effectively and selectively shifts, in synchronism with the operation of said LCD driver circuit, said image display plane in a direction opposite to said given direction in which said image display position shifting is carried out. Even if the LCD has a larger number of scanning lines or the pixel shift operation is performed by a larger number of times, the resolution can be effectively improved.
