<p>A display device having a display area for displaying a substantially planar image of an object, the display device further comprising a substantially transparent sheet or LCD overlying the display area and carrying an array of less transparent areas which co-operate with a first pattern generated in the plane of the image by the display device, thereby producing a resultant Moiré interference background pattern which appears to lie in a different plane to that of the image. This arrangement can provide an enhanced 3D effect in a compact and easily fabricated device without the use of additional electrical power.</p> |
