Visual display with increased field of view
First Claim
1. An image display device comprising:
- an optical display panel having a center region and a peripheral region that at least partially surrounds the center region;
a plurality of light emitting pixels disposed within the optical display panel such that a greater pixel density exists in the center region than in the peripheral region; and
a pattern of drivers and electrodes disposed on a substrate supporting the plurality of light emitting pixels,wherein the center region includes at least one center-region pixel and the peripheral region includes at least one peripheral region pixel having a physical size greater than a size of the center region pixel,wherein the physical size of the at least one peripheral-region pixel is increased in two dimensions to produce a lower pixel density in the peripheral region as compared to the center region, andwherein the pattern of drivers and electrodes are disposed underneath the plurality of light emitting pixels in a configuration where a lower density of drivers and electrodes exist in the peripheral region as compared to the center region.

Abstract
This invention provides a continuous display with non-uniform pixel density, forming a foveated display. A single, continuous display has a higher pixel density at the center of the display than at the periphery of the display. Where two continuous displays are used in accordance with the present invention, the central forward gaze of the viewer'"'"'s image will be displayed in high resolution while the leftmost portion of the left eye display will be in low resolution and the rightmost portion of the right eye display will be in low resolution. The pixel resolution of the visual display may correspond to the visual acuity of the human eye. A foveated image display system using a continuous display with non-uniform pixel density increases the field of view while reducing the image bandwidth. A foveated image display system may be hardware-based by employing anamorphic lenses or sensors rather than relying upon image interpolation to modify the resolution of the resultant image data communicated to the continuous display with non-uniform pixel density.
