Patent number: 11955038Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The display may have a number of independently controllable viewing zones. Each viewing zone displays a respective two-dimensional image. Each eye of the viewer may receive a different one of the two-dimensional images, resulting in a perceived three-dimensional image. The electronic device may include display pipeline circuitry that generates and processes content to be displayed on the lenticular display. Content generating circuitry may generate content that includes a plurality of two-dimensional images, each two-dimensional image corresponding to a respective viewing zone. Pixel mapping circuitry may be used to map the two-dimensional images to the array of pixels in the lenticular display. The array of pixels may have a diagonal layout. An offset map may be used by the pixel mapping circuitry to account for the diagonal layout.Type: GrantFiled: June 11, 2021Date of Patent: April 9, 2024Assignee: Apple Inc.Inventors: Sheng Zhang, Chaohao Wang, Yi-Pai Huang, Yue Ma, Ping-Yen Chou, Fu-Chung Huang

Publication number: 20240112628Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. A plurality of lenticular lenses may 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 a number of independently controllable viewing zones. The viewer may be particularly susceptible to artifacts caused by crosstalk at the edge viewing zones within the primary field of view of the display. Certain types of content may also be more vulnerable to crosstalk than other types of content. Therefore, to mitigate crosstalk artifacts, the pixel value for each pixel may be adjusted based on the viewing zone of the respective pixel and content information (such as texture information or brightness information) associated with the respective pixel.Type: ApplicationFiled: December 14, 2023Publication date: April 4, 2024Inventors: Yunhui Hou, Yi-Pai Huang, Fu-Chung Huang, Sheng Zhang, Chaohao Wang, Ping-Yen Chou, Yi Huang, Juan He, Alfred B.

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.

Publication number: 20230350105Abstract: A lenticular display may be formed with convex curvature. The lenticular display may have a lenticular lens film with lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display. To enable more curvature in the display while ensuring satisfactory stereoscopic display performance, the display may have stereoscopic zones and non-stereoscopic zones. A central stereoscopic zone may be interposed between first and second non-stereoscopic zones. The non-stereoscopic zones may have more curvature than the stereoscopic zone. To prevent crosstalk within the lenticular display, a louver film may be incorporated into the display. The pixel array may have a diagonal layout and may be covered by vertically oriented lenticular lenses.Type: ApplicationFiled: July 6, 2023Publication date: November 2, 2023Inventors: Yi-Pai Huang, Manjap Singh, Cheng-Ho Yu, ByoungSuk Kim, Yi Huang, Hitoshi Yamamoto, Mathew K.

Publication number: 20230326380Abstract: 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. To mitigate jaggedness in a curved edge of the active area, control circuitry may modify input pixel data for the display using dimming factors. Each brightness value of the pixel data may be multiplied by a corresponding dimming factor such that the curved edge has a smooth appearance. Each physical pixel in the display may have an associated perceived pixel that is based on an appearance of that physical pixel through the lenticular lens film. The perceived pixel may have a different footprint than its corresponding physical pixel. The dimming factors for boundary smoothing in the curved edges may be based on the perceived pixels.Type: ApplicationFiled: February 7, 2023Publication date: October 12, 2023Inventors: Juan He, Yi Huang, Jun Qi, ByoungSuk Kim, Hao Chen, Ping-Yen Chou, Yi-Pai Huang, Yue Ma, Sheng Zhang
