Publication number: 20200049994Abstract: A near-eye display device reduces vergence accommodation conflict by adjusting a tilt and/or distance of a focal plane of a display panel based on scene depth statistics. For example, many three-dimensional (3D) scenes have closer objects in the lower visual field and farther objects in the upper visual field. Changing the tilt of the focal plane of the display panel to match average 3D screen depths reduces the discrepancy between vergence and accommodation distances. In some embodiments, the near-eye display device employs a fixed tilt of the display panel to match average scene depth statistics across a variety of scenes. In some embodiments, the near-eye display device dynamically adjusts the pitch and yaw of the focal plane of the display panel to match scene statistics for a given scene.Type: ApplicationFiled: August 13, 2018Publication date: February 13, 2020Inventors: Ivana TOSIC RODGERS, Oscar MARTINEZ, Jerome CAROLLO

Publication number: 20200041790Abstract: An optical device, such as a head mounted display, includes a display that emits light, a reflector, and a partially reflective circular polarizer (RCP) positioned between the reflector and a user's eye or eyes. The reflector can be partially reflective. The partially reflective circular polarizer, the reflector, or both, can be curved. Light from the display is reflected one or more times by the reflector. The RCP can include one or more of a quarter-wave plate (QWP), a reflective polarizer layer, a linear polarizer, a supportive substrate, and an anti-reflective film. The reflector can include a mirror coating and an anti-reflection coating.Type: ApplicationFiled: August 2, 2018Publication date: February 6, 2020Inventors: Oscar MARTINEZ, Yi QIN, Xinda HU
