Abstract
We propose a design of a retinal-projection-based near-eye display for achieving ultra-large field of view, vision correction, and occlusion. Our solution is highlighted by a contact lens combo, a transparent organic light-emitting diode panel, and a twisted nematic liquid crystal panel. Its design rules are set forth in detail, followed by the results and discussion regarding the field of view, angular resolution, modulation transfer function, contrast ratio, distortion, and simulated imaging.
Highlights
In recent years, the notion of augmented reality (AR) [1] has been going viral thanks to the staggering venture investments and countless media hypes
We introduced combiner-based [23,24,25], waveguide-based [26,27,28], and retinal-projection-based near-eye displays (NEDs) [29,30,31], which are merged with the prescription or corrective lenses for vision correction
Our simulation is implemented with an optical design software Code V (Synopsys), which is based on the ray tracing [44] and capable of analyzing the imaging properties, including modulation transfer function (MTF), distortion, and imaging simulation
Summary
The notion of augmented reality (AR) [1] has been going viral thanks to the staggering venture investments and countless media hypes. With AR, users are able to view the real world overlaid with computer-generated imagery and information. Such user experience can be realized by two types of optical solutions, i.e. video see-through displays and optical see-through near-eye displays (NEDs) [2]. Retinal-projection-based or direct-view NEDs―including retinal scanning [18,19,20], pinlight [21], and iOptik [22], in which the image is directly projected on the retina―may have both compactness and large FOVs, and yet each one has its own issues. The manufacturability of such contact lens remains to be improved
