Abstract: A display device, such as a head mounted device (HMD), displays a virtual scene. The display device includes a motion tracker for detecting rotation of the display device. The display device also includes a processor that is configured to selectively maintain or modify a position of an array of rendered pixels relative to the virtual scene in response to the detected motion. The processor is also configured to upsample the rendered pixels to generate values of display pixels for presentation by the display device. The processor is further configured to translate the values of the display pixels in a rendering plane of the display device based on the detected motion. The translated values of the display pixels can then be presented on a display of the display device.

Abstract: Embodiments of the disclosure describe a tileable display panel including a screen layer to display a unified image, an illumination layer including a two-dimensional array of lamps, and a display layer disposed between the screen layer and illumination layer. The display layer includes a plurality of pixelets each positioned to be illuminated by a corresponding lamp from the illumination layer to project a magnified image sub-portion corresponding to a received subset. The magnified image sub-portions collectively blend together to form the unified image displayed on the screen layer. Embodiments of the disclosure further include illumination layer control logic to determine a brightness value of each of the received subsets of pixel data, and adjust an illumination setting to reduce or increase an illumination output of a lamp in the illumination layer based, at least on part, on the brightness values of the corresponding subset of pixel data.

Abstract: A method for aligning optical layers of a multi-layer display includes displaying a dark screen image on each of a plurality of transmissive pixel arrays separated from each other by spacing regions. The transmissive pixel arrays are disposed on a display layer of the multi-layer display. The display layer is illuminated with a plurality of illumination sources of an illumination layer disposed behind the display layer. Each of the illumination sources corresponds to one of the transmissive pixel arrays to illuminate the corresponding one of the transmissive pixel arrays. An illumination pattern is cast onto a screen layer disposed in front of the display layer. The illumination pattern includes bright regions due to overlapping illumination cast from adjacent ones of the transmissive pixel arrays. The bright regions of the illumination pattern cast onto the screen layer are analyzed to identify misalignments between the display layer and the illumination layer.

Abstract: A tileable display panel includes an illumination layer, a display layer, and a screen layer. The display layer is disposed between the screen layer and the lamp layer and includes pixelets separated from each other by spacing regions. Each of the pixelets is positioned to be illuminated by lamp light from the illumination layer and to project a magnified image sub-portion onto the backside of the screen layer such that the magnified image sub-portions collectively blend together to form a unified image on the screen layer which covers the spacing regions on the display layer. Each of the pixelets includes core pixels having a common size and a first separation pitch and peripheral pixels surrounding the core pixels on two or more sides which provide a higher image resolution in overlap regions on the screen layer when the magnified image sub-portions overlap on the screen layer.
