Patent number: 11984091Abstract: Systems, methods, and devices are provided to selectively perform a frame replay at various stages of an image processing pipeline for an electronic display. Image processing circuitry may include first compensation circuitry that compensates for a first compensation factor relating to a first physical parameter of an electronic display and second compensation circuitry that compensates for a second compensation factor relating to a second physical parameter of the electronic display. A first tap point that enables the image frame to be stored and reused may be located between the first compensation circuitry and the second compensation circuitry, while a second tap point may be located after the second compensation circuitry.Type: GrantFiled: June 13, 2022Date of Patent: May 14, 2024Assignee: Apple Inc.Inventors: Peter F Holland, Mahesh B Chappalli

Publication number: 20240119886Abstract: An electronic device may include a display panel. When content of an image frame is expected to consume relatively higher amounts of power, a controller of the electronic device may operate a switch to change a power supply of the display panel to be a power management integrated circuit of the electronic device. However, when content of an image frame is expected to consume relatively less amounts of power, the controller may operate the switch to change the power supply of the display panel to be a power supply of an electronic display, such as a power supply used to power driver circuitry of the electronic display.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Inventors: Peter F Holland, Christopher P Tann, Ramana V Rachakonda

Publication number: 20240078946Abstract: This disclosure provide various techniques for reducing the impact of an under-display sensor on an electronic display. Some sensors (e.g., a proximity sensor), when activated, may emit a beam through the electronic display. Emitting the beam through the electronic display may cause pixels to display a different brightness level than intended. To address this, an electronic device may use spatially weighted statistics to determine a timing profile for the under-display sensor to reduce the sensor's interference on the pixels. Additionally, a compensation voltage may be applied to further reduce or eliminate the impacts of the interference.Type: ApplicationFiled: January 25, 2023Publication date: March 7, 2024Inventors: Peter F.

Publication number: 20240038154Abstract: An electronic device may include processing circuitry configured to generate a first frame of image content and a second frame of image content. The second frame of image content is different from the first frame of image content. The electronic device may also include a display configured to display the first frame of image content at a first refresh rate. In response to receiving the second frame of image content, the electronic device may initially increase the refresh rate before tapering back to the first refresh rate while displaying the second frame of image content.Type: ApplicationFiled: July 19, 2023Publication date: February 1, 2024Inventors: Jie Won Ryu, Ing-Jye Wang, Alex H Pai, Alexandre V Gauthier, Ardra Singh, Arthur L Spence, Gihoon Choo, Hyunsoo Kim, Hyunwoo Nho, Jenny Hu, Graeme M Williams, Jongyup Lim, Kingsuk Brahma, Marc J DeVincentis, Peter F Holland, Shawn P Hurley

Publication number: 20240013692Abstract: To reduce overall power consumption for an electronic display power management integrated circuit (PMIC), one of multiple electric power converters and/or electric power regulators may be selected based on an electrical load (e.g., due to the total brightness of the content displayed) on the electronic display at a given moment. In some embodiments, the PMIC may include a less efficient heavy load converter designed with high-current handling capability and a more efficient light load (e.g., low current) converter with lower current handling capability. A controller may dynamically select between the converters depending on a present load or an expected load on the electronic display.Type: ApplicationFiled: June 21, 2023Publication date: January 11, 2024Inventors: Jie Won Ryu, Ardra Singh, Arthur L. Spence, Christopher P. Tann, Chun Lu, Daniel J. Drusch, Hyunwoo Nho, Jongyup Lim, Kingsuk Brahma, Marc J. DeVincentis, Mohammad Ali Jangda, Paolo Sacchetto, Peter F. Holland, Shawn P. Hurley, Wei H.

Patent number: 11868162Abstract: A method may include receiving, via a processor, a frame of image data, such that the frame of image data may include an active portion and an idle portion. The active portion may include data for presenting one or more images via a first display of a first electronic device. The method may also include receiving a signal from a second electronic device during the idle portion of the frame of image data, such that the second electronic device is separate from the first display. The method may then involve initiating processing of the frame of image data in response to the signal being received from the second electronic device.Type: GrantFiled: December 16, 2022Date of Patent: January 9, 2024Assignee: Apple Inc.Inventors: Assaf Menachem, Peter F.

Publication number: 20230410718Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. Display artifacts caused by a light emitter that operates through a display may be referred to as emitter artifacts. To mitigate emitter artifacts, operating conditions for a display frame may be used to determine an optimal firing time for the light emitter during that display frame. The operating conditions used to determine the optimal firing time may include emitter operating conditions, display content statistics, display brightness, temperature, and refresh rate. Operating conditions from one or more previous frames may be stored in a frame buffer and may be used to help determine the optimal firing time for the light emitter during a display frame. Pixel values for the display may be modified to mitigate emitter artifacts.Type: ApplicationFiled: March 15, 2023Publication date: December 21, 2023Inventors: Jenny Hu, Chaohao Wang, Christopher E Glazowski, Clint M Perlaki, David R Manly, Feng Wen, Graeme M Williams, Hei Kam, Hyun H Boo, Kevin J Choboter, Kyounghwan Kim, Lu Yan, Mahesh B Chappalli, Mark T Winkler, Na Zhu, Peter F Holland, Tong Chen, Warren S Rieutort-Louis, Wenrui Cai, Ximeng Guan, Yingying Tang, Yuchi Che

Patent number: 11823642Abstract: An electronic display pipeline may process image data for display on an electronic display. The electronic display pipeline may include burn-in compensation statistics collection circuitry and burn-in compensation circuitry. The burn-in compensation statistics collection circuitry may collect image statistics based at least in part on the image data. The statistics may estimate a likely amount of non-uniform aging of the sub-pixels of the electronic display. The burn-in compensation circuitry may apply a gain to sub-pixels of the image data to account for non-uniform aging of corresponding sub-pixels of the electronic display. The applied gain may be based at least in part on the image statistics collected by the burn-in compensation statistics collection circuitry.Type: GrantFiled: May 24, 2022Date of Patent: November 21, 2023Assignee: Apple Inc.Inventors: Mahesh B.
