Abstract
To effectively make a mesh of out lines between pixels by a pixel diffusion and at the same time to facilitate a focusing of an image by the observer, an optical filter for diffusing each pixel of a display device into a plurality of parts by utilizing diffraction or refraction is interposed between the display device having an image pattern in a mosaic form and an observer. The optical filter surface performs the pixel diffusion so that a sight angle, of a gap which does not pass light between the neighboring pixel after the pixel diffusion, as viewed from the observer on the focal plane on which the image displayed by the display device is observed by the predetermined observer is substantially a recognizable limit view angle of the observer.
Claims17
An image display apparatus for displaying an image to a predetermined observation point remote from said apparatus having a predetermined recognizable limit view angle, composing:
- a display device having a plurality of pixels arranged in a mosaic pattern;
- and
- an optical filter surface disposed on a front face of said display device, so that said filter surface is disposed between said display device and said predetermined observation point, for diffusing each pixel of said display device into a plurality of parts by utilizing diffraction or refraction,
- wherein a pixel mask gap interval is generated, corresponding in width to said predetermined recognizable limit view angle, between neighboring pixels after said diffusing of each of said pixels by said optical filter surface resulting in a focused display image viewable at said observation point.
A filter for an image display apparatus for displaying an image at a predetermined observation point relative to said image display apparatus having a predetermined recognizable limit view angle, comprising:
- a display device having a plurality of pixels arranged in a mosaic pattern;
- and
- an optical filter surface disposed on a front face of said display device, so that the filter surface is disposed between said display device and said predetermined observation point, for diffusing each pixel of said display device into a plurality of parts by utilizing diffraction or refraction,
- wherein a pixel mask gap interval is generated, corresponds in distance to the predetermined recognizable limit view angle, between neighboring pixels after said diffusing of each of said pixels by said optical filter surface resulting in a focused display image viewable at said observation point.
