Abstract: Introduced herein are various techniques for displaying virtual and augmented reality content via a head-mounted display (HMD). The techniques can be used to improve the effectiveness of the HMD, as well as the general experience and comfort of users of the HMD. An HMD may increase and/or decrease the resolution of certain areas in digital content that is being viewed to more accurately mimic a user's high resolution and low resolution fields of view. For example, the HMD may monitor the user's eye movement to identify a focal point of the user's gaze, and then increase the resolution in an area surrounding the focal point, decrease the resolution elsewhere, or both. Predictive algorithms could also be employed to identify which areas are likely to be the subject of the user's gaze in the future, which allows the HMD to present the regionally-focused content in real-time.

Abstract: Most large public displays systems are built with smaller modules populated with light emitting pixels devices which are then connected together to form a larger surface which is the combined surface area of all the modules.

This problem is aggravated by the fact that the modules are generally rectangular, which causes that their edges continue from edge to edge of the whole display, causing darker lines on the display surface, generally horizontal and vertical darker lines. This invention discloses adding light emitting pixel devices on the supporting and connecting structure so that the image is continuous across the full display area.
