Reduced spatial resolution is a limitation of some near-eye light field displays. Douglas Lanman and Luebke (2013) indicated that the resolution is proportional to the ratio of the microlens focal length to the distance of the display from the eye. This means that a compact form factor, while desirable, results in a lower resolution. To have a higher resolution means you would have a bigger, bulkier display. Furthermore, they wrote that “practical applications will necessitate manufacturing larger microdisplays with smaller pixel pitches, enabling wide fields of view and high resolutions, respectively.” <ref name=”2”></ref>

The main benefits of the near-eye light field displays are reduced thickness and weight. In the 2013 prototype this was achieved by substituting a compact microlens array for compound magnifying optics. Adding to this, the gadget addresses the accommodation-convergence conflict with binocular configurations by approximating retinal defocus blur. It also accounts for the user’s glasses or contact prescription through software <ref name=”2”></ref><ref name=”5”></ref>.

 

On the other hand, reduced spatial resolution was the primary limitation of this device. Lanman and Luebke (2013) indicated that the resolution is proportional to the ratio of the microlens focal length to the distance of the display from the eye. This means that a compact form factor, while desirable, results in a lower resolution. To have a higher resolution means you would have a bigger, bulkier display.

The near-eye light field stereoscope prototype of 2015 also addresses the accommodation-convergence conflict that leads to motion sickness, resulting in a more natural and flexible experience. In this case, the gadget uses two layers of LCD separated by approximately 5 millimeters. These send an entire four-dimensional (4D) light field of images so the eye can set focus between objects more naturally <ref name=”11”> Pirzada, Usman (2015).
