Abstract: Technologies for virtual reality display include a computing device coupled to a head-mounted display device. The head-mounted display includes a display panel, a pixel emission controller, and a pancake lens assembly. The display panel includes a display surface that emits light as multiple pixels. The pancake lens assembly includes folded optics to direct light to an eye box. The pixel emission controller applies an emission profile to each pixel of the light as a function of the position on the display surface of the corresponding pixel. The emission profile is determined based on an optical coupling between the position on the display surface through the pancake lens assembly to the eye box. The beam width of each pixel may decrease and the beam angle relative to an optical axis may increase as distance from the optical axis increases. Other embodiments are described and claimed.

Abstract: The present disclosure is directed to systems and methods of transferring bulk data, such as OLED compensation mask data, generated by a source device to a sink device using a high-bandwidth embedded DisplayPort (eDP) connection contemporaneous with an ENABLED Panel Self-Refresh (PSR) mode. Upon ENABLING the PSR mode, the source control circuitry causes the source transmitter circuitry, the sink receiver circuitry, and the eDP high-bandwidth communication link to remain active rather than inactive. The source control circuitry generates one or more data transport units (DTUs) having a header portion that contains data indicative of the presence of a bulk data payload and the non-display status of the bulk data payload carried by the DTUs.

Abstract: Disclosed herein are display panels, display panel stacks, and techniques to manufacture such display panel stacks where a polarizer is provided for each illumination element of the display panel stack. A polarizer can be formed onto each individual illumination element once the illumination element is transferred to the backplane. The polarizer can be arranged to polarize light emitted from the illumination element and light incident on the display from ambient.

Abstract: Techniques for implementing aging compensation for a display are described. An example of an electronic device includes a display with a plurality of pixels, each pixel including one or more Light Emitting Diodes (LEDs). The electronic device also includes a wear compensation unit. The wear compensation unit is configured to receive input frame data corresponding to content to be displayed, determine a wear compensation configuration that identifies which of the plurality of pixels are compensated pixels and which are non-compensated pixels, and generate output frame data by adjusting the input frame data associated with the compensated pixels based on a degree of aging of the LEDs of the compensated pixels.

Abstract: Techniques for implementing aging compensation for a display are described. An example of an electronic device includes a display comprising pixels, each pixel comprising one or more Light Emitting Diodes (LEDs). The electronic device also includes a display aging compensation unit to receive input frame data corresponding to content to be displayed, adjust the input frame data to generate output frame data based on a degree of aging of the LEDs, and send the output frame data to the display. The electronic device also includes a display aging monitoring and compensation processing unit to accumulate aging data that describes the degree of aging of the LEDs. The aging data is accumulated by sampling the output frame data at a sampling point in accordance with a sampling configuration, and the aging data collected at the sampling point is applied to other pixels in the vicinity of the sampling point. The display aging monitoring and compensation processing unit determines a degree of compensation to apply to the other pixels based on the aging data collected at the sampling point and an aging difference between the other pixels and the sampling point.
