  • Patent number: 7268943
    Abstract: The present invention relates to a 3D image display apparatus of a parallax barrier method. In the 3D image display apparatus of a parallax barrier method, a parallax barrier of which a transparent slit portion is formed in a tooth shape is adapted, so that it is possible to decrease an optical bad feeling due to Moire pattern. When designing the pitch S of the parallax barrier, in the case that the parallax barrier is disposed behind the image panel the pitch S is S=2Pk(V+D)/V, and in the case that the parallax barrier is disposed in front of the image panel, the pitch S is S=2Ph(V?D)/V. In the 3D image reproducing apparatus according to the present invention, an excellent performance can be achieved as compared to the simple 3D image. The common image can be easily converted into a 3D image using an on and off operation using the electronic shutter.
