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

Patent number: 11882752Abstract: An electronic device display may have an active area with pixels. An optical sensor may be formed under a sensor region in the active area. During operation, ambient light and/or other light associated with the optical sensor may pass through the sensor region. To ensure that the light for the optical sensor can pass through the display, the display may have one or more layers with sensor openings such as a metal layer and a pressure sensitive adhesive layer that attaches the metal layer to the pixels of the display. To help minimize visibility of the openings in the sensor region, the pressure sensitive adhesive layer may be configured to have a reflectivity that matches the appearance of the display in the sensor region to surrounding areas. Undesired light output uniformity can be reduced by ensuring that the substrate material in the display has a low light absorption coefficient.Type: GrantFiled: July 16, 2021Date of Patent: January 23, 2024Assignee: Apple Inc.Inventors: Zhao Wang, Alexis G. Soyseven, David S. Hum, Graeme M. Williams, Ing-Jye Wang, Jae Won Choi, Jimmy H. Huang, Ming Xu, Sungki Lee, Timothy H. Ellis, Yu Cheng Chen, Yuchi Che

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: 11810494Abstract: An electronic device may include an electronic display having multiple display pixels to display an image based on analog voltage signals. The electronic device may also include optical calibration circuitry to generate digital-to-analog converter (DAC) data based on image data associated with the image and dither circuitry to reduce a bit-depth of the DAC data, generating dithered DAC data. Additionally, the electronic device may include a gamma generator having one or more DACs to generate the analog voltage signals based on the dithered DAC data, which may instruct the gamma generator to generate the analog voltage signals indicative of the image data.Type: GrantFiled: August 16, 2022Date of Patent: November 7, 2023Assignee: Apple Inc.Inventors: Jie Won Ryu, ByoungSuk Kim, David S Zalatimo, Graeme M Williams, Hyunsoo Kim, Hyunwoo Nho, Jesse R Manders, Kingsuk Brahma, Li-Xuan Chuo, Sachiko Oda, Shatam Agarwal, Yao Shi

Patent number: 11295664Abstract: In some embodiments, a device includes a light-emitting display, and an optical emitter positioned behind the light-emitting display. The optical emitter is configured to emit light through the light-emitting display. A processor is configured to synchronize a first illumination timing of the optical emitter and a second illumination timing of the light-emitting display. In some embodiments, a device includes an optical transceiver processor and a display processor. The display processor is configured to output timing information to a light-emitting display and to the optical transceiver processor, and the optical transceiver processor is configured to cause an optical transceiver to emit or receive light in synchronization with the timing information output by the display processor.Type: GrantFiled: March 11, 2020Date of Patent: April 5, 2022Assignee: Apple Inc.Inventors: Tong Chen, Dong Zheng, Graeme M. Williams, Mark T. Winkler, Warren S. Rieutort-Louis, Yuchi Che

Patent number: 11120747Abstract: A display may have an active area that includes display pixels. The display may include an inactive notch region that extends into the active area. Data lines may provide image data from display driver circuitry to the display pixels. The image data may include data signals that correspond to portions of the display that do not include pixels, such as the inactive notch region. The null data signals may cause nonuniformities in the displayed image. The null data signals may be adjusted to minimize the nonuniformities. Null data signals corresponding to the inactive notch region may be adjusted to have gray levels that gradually decrease with distance from the border between the inactive notch and the active area. All of the data signals corresponding to the inactive notch may be set to a uniform gray level.Type: GrantFiled: February 27, 2020Date of Patent: September 14, 2021Assignee: Apple Inc.Inventors: Koorosh Aflatooni, Warren S.

Patent number: 10573236Abstract: A display may have an array of pixels. Due to the presence of a notch in the display, the display may have some rows that are shorter than other rows in the display, and accordingly different gate line loading. To account for the gate line loading variations, the display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. In other arrangement, luminance adjustment circuitry may receive image data and generate corresponding compensated image data to account for gate line loading variations between rows of pixels in the display. The image data may be compensated based on the location of the pixel, the gray level of the image data, the display brightness, and/or temperature.Type: GrantFiled: February 22, 2019Date of Patent: February 25, 2020Assignee: Apple Inc.Inventors: Shengkui Gao, Graeme M.
