摘要:
An image display apparatus utilizes differences between the recognition or discrimination system of the human eye and the eye-movement system of the human eye to present in image which has an enhanced quality of solidness and yet does not cause eye fatigue. The image display apparatus includes an image source, such as a color cathode ray tube; a main image display screen for displaying an image of the image source without substantially reducing its resolution; a first, inner frame surrounding the main image display screen; a moderated image display screen for displaying a peripheral part of the image of the image source with reduced resolution; and a second, outer frame surrounding the moderated image display screen. In one embodiment, the moderated image display screen is formed of a lamination of a multi-layer Fresnel lens and an opal scattering plate. In another embodiment the moderated image display screen consists of a lamination of a multi-layer Fresnel lens, an opal scattering plate, and a fly-eye lens.
