Publication number: 20240045502Abstract: In an embodiment, an electronic device includes a display and an eye tracker. The display includes one or more foveated areas. In the embodiment, the eye tracker is configured to collect eye tracking data regarding a gaze of one or more eyes of a user on the display. The electronic device also includes processing circuitry operatively coupled to the display. In the embodiment, the processing circuitry is configured to receive an indication of a motion associated with the gaze from the eye tracker. The processing circuitry is also configured to determine a previous location associated with the gaze during a previous frame and a target position associated with the gaze during a target frame. In the embodiment, the processing circuitry is configured to expand one or more foveated areas of the display adjacent a previous position of the gaze of the user.Type: ApplicationFiled: October 17, 2023Publication date: February 8, 2024Inventors: Yang Li, Alexandre Chapiro, Mehmet N. Agaoglu, Nicolas Pierre Marie Frederic Bonnier, Yi-Pai Huang, Chaohao Wang, Andrew B. Watson, Pretesh A. Mascarenhas

Publication number: 20240031554Abstract: An electronic device may include a stereoscopic display with a plurality of lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have different viewing zones that account for horizontal parallax as a viewer moves horizontally relative to the display. The display may be dimmed globally based on the detected vertical position of the viewer. The magnitude of dimming applied to the display may increase with increasing deviation of the viewer from a baseline viewing angle. The display may render content that compensates for the real-time vertical position of the viewer. Another option for the stereoscopic display is to include a lens film that has an array of lenses. Each lens in the array of lenses spreads light in the horizontal direction and the vertical direction.Type: ApplicationFiled: September 29, 2023Publication date: January 25, 2024Inventors: Yi-Pai Huang, Yang Li, Yi Huang, Pretesh A Mascarenhas, Menelik Baye Yimam, Guru Moorthy Ravi, Yunhui Hou, Fu-Chung Huang, Sheng Zhang

Publication number: 20240022705Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have a number of independently controllable viewing zones. A eye and/or head tracking system may use a camera to capture images of a viewer of the display. Control circuitry in the electronic device may use the captured images from the eye and/or head tracking system to determine which viewing zones are occupied by the viewer's eyes. The control circuitry may disable or dim viewing zones that are not occupied by the viewer's eyes in order to conserve power. An unoccupied viewing zone and an adjacent, occupied viewing zone may display the same image to increase sharpness in the display.Type: ApplicationFiled: July 20, 2023Publication date: January 18, 2024Inventors: Yi-Pai Huang, Felipe Bacim De Araujo E Silva, Ping-Yen Chou, ByoungSuk Kim, Chaohao Wang, Yi Huang, Michael J. Rockwell, Seung Wook Kim, Pretesh A. Mascarenhas

Patent number: 11450297Abstract: An electronic device such as a head-mounted device may have a display that is viewable by a user from eye boxes. The electronic device may have a gaze tracking system that monitors a user's eyes in the eye boxes to gather gaze direction information. The display may have a central portion and a peripheral portion. The peripheral portion may have a lower resolution than the central portion and may be used in displaying content that is viewable in a user's peripheral vision. During operation, control circuitry in the electronic device may adjust peripheral content on the peripheral portion to correct for parallax-induced mismatch between the peripheral content and central content on the central portion of the display. The control circuitry may also depower peripheral pixels that are determined to be unviewable based on the gaze direction. Diffusers may be used to hide seams between the central and peripheral display portions.Type: GrantFiled: July 3, 2019Date of Patent: September 20, 2022Assignee: Apple Inc.Inventors: William W. Sprague, David W. Lum, Pretesh A. Mascarenhas, Shubham A. Gandhi, Tyler B. Milhem
