Techniques for designing display (glasses) devices in light-weight and small footprint are described. To reduce the cost, weight and volume of the display devices, only one imager is used. An optical engine (cube) is provided to split optical images from the imager into a first (left) portion and a second (right) portion. Each of the portions is redirected via one or more optical lenses to a predefined path, where the optical lenses are based upon polarization volume hologram (PVH) lenses in one embodiment, all having different optical characteristics to diffract light beams at predefined angles.

The optical image is picked up by a focal lens from a microdisplay in the enclosure. The optical image is in lower resolution but received by the optical fiber at a twice speed as the normal refresh rate (e.g., 120 Hz vs. 60 Hz). Two successive images in lower resolution are combined at or near the other end of the optical fiber to generate a combined image at higher resolution, where the combined image is refreshed and perceived at the normal refresh rate.

In one aspect, a circuit is designed to include a set of memory cells, a horizontal decoder and a vertical decoder. An input image is received at an interface to the memory, the input is expanded into two separate frames in the memory, where the size of each of the two frames is identical to that of the input image. Image data in at least one of the two frames are modulated in amplitude and/or in phase. The first and second frames are then read out or displayed alternatively at twice the refresh rate originally set for the input image to achieve the perceived resolution.
