It can be made with a [[lens array]]. Near-eye lightfield displays have been made in a variety of types, including microlens-based, sequential projection, and stacked LCD. An example of a sequential projection display is from [[CREAL]].

A near-eye lightfield display may be paired with a computer system that automatically updates the rendering viewpoint according to positional and orientational sensor data, such as a [[virtual reality]] system or [[augmented reality]].

Sharp images from out-of-focus display elements are depicted by synthesizing these light fields that correspond to virtual scenes located within the viewer’s natural accommodation range. [[Lanman]] and Luebke (2013) mentioned that “conventional displays are intended to emit light isotropically. In contrast, a light field display supports the control of tightly-clustered bundles of light rays, modulating radiance as a function of position and direction across its surface.”<ref name=”2”>Lanman, D. and Luebke, D.

Traditional HMDs only provide a single display plane; without a proper focus cue, the display decouples accommodations from the vergence of the eyes. Since there is a mismatch, the observer has to rely only on the binocular vision to perceive a 3D space. This can lead to visual discomfort, fatique, eye strain, and headaches <ref name=”6”> Stanford Computational Imaging Lab (2015). The Light Field Stereoscope - SIGGGRAPH 2015 [Video].

There have been demonstrations that light field displays allow for small form factors of NEDs. This was made by placing a [[microlens array]] on a small screen close to the eye. In near-eye light field displays the image created appears to be floating outside the physical gadget enclose, and the observer can accommodate with a narrow range. However, the lens used in the studies have a tradeoff between achieved spatial resolution and the supported depth range <ref name=”2”></ref><ref name=”7”> Huang, Fu-Chung, Chen, K. and Wetzstein, G. (2015). The Light Field Stereoscope: Immersive Computer Graphics via Factored Near-Eye Light Field Displays with Focus Cues. ACM Transactions on Graphics, 34(4)</ref>. Another technique used to implement light field displays is to stack liquid crystal displays (LCDs). In this case, the image formation is multiplicative, allowing for correct or nearly-correct focus cues to be supported over larger depth ranges. Alternatively, it reduces the number of required display planes <ref name=”7”></ref>.
