Patent number: 12292664Abstract: To minimize the width of a non-light-emitting border region around an opening in the active area, data lines may be stacked in the border region. Data line portions may be formed using three metal layers in three different planes within the border region. A metal layer that forms a positive power signal distribution path in the active area may serve as a data line portion in the border region. A metal layer may be added in the border region to serve as a data line portion in the border region. Data line signals may also be provided to pixels on both sides of an opening in the active area using supplemental data line paths. A supplemental data line path may be routed through the active area of the display to electrically connect data line segments on opposing sides of an opening within the display.Type: GrantFiled: October 26, 2023Date of Patent: May 6, 2025Inventors: Shin-Hung Yeh, Warren S Rieutort-Louis, Abbas Jamshidi Roudbari, Chien-Ya Lee, Lun Tsai

Patent number: 12288522Abstract: An electronic device includes a display and a sensor underneath the display. The display has a full pixel density region and a reduced pixel density region. Compared to pixels in the full pixel density region, pixels in the reduced pixel density region can be controlled using overdriven power supply voltages, overdriven scan control signals, different initialization and reset voltages, and can include capacitors and transistors with different physical and electrical characteristics. Gate drivers provide scan signals to pixels in the full pixel density region, whereas overdrive buffers provide overdrive scan signals to pixels in the reduced pixel density region. The pixels in the full pixel density region and the pixels in the reduced pixel density region can be controlled using different black level or gamma settings for each color channel and can be adjusted physically to match luminance, color, as well as to mitigate differences in temperature and aging impact.Type: GrantFiled: July 11, 2023Date of Patent: April 29, 2025Assignee: Apple Inc.Inventors: Shyuan Yang, Salman Kabir, Ricardo A Peterson, Warren S Rieutort-Louis, Ting-Kuo Chang, Qing Li, Yuchi Che, Tsung-Ting Tsai, Feng Wen, Abbas Jamshidi Roudbari, Kyounghwan Kim, Graeme M Williams, Kingsuk Brahma, Yue Jack Chu, Junbo Wu, Chieh-Wei Chen, Bo-Ren Wang, Injae Hwang, Wenbing Hu

Patent number: 12207512Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.Type: GrantFiled: November 17, 2023Date of Patent: January 21, 2025Assignee: Apple Inc.Inventors: Cheng-Ho Yu, Chin-Wei Lin, Shyuan Yang, Ting-Kuo Chang, Tsung-Ting Tsai, Warren S.

Patent number: 12175907Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. To mitigate artifacts caused by a light emitter operating through a display, the display may have a higher density of thin-film transistor sub-pixels than emissive sub-pixels. This allows for a region in the display to include emissive sub-pixels but be free of thin-film transistor sub-pixels. The light emitter may operate through this region in the display. Additionally, to reduce the amount of space occupied in the inactive area of a display by gate driver circuitry, at least a portion of the gate driver circuitry may be positioned in the active area of the display. To accommodate the gate driver circuitry, emissive sub-pixels may be laterally shifted relative to corresponding thin-film transistor sub-pixels.Type: GrantFiled: September 28, 2023Date of Patent: December 24, 2024Assignee: Apple Inc.Inventors: Shyuan Yang, Cheng-Chih Hsieh, Jonathan H Beck, Yuchi Che, Tsung-Ting Tsai, Warren S Rieutort-Louis, Abbas Jamshidi Roudbari, Ting-Kuo Chang, Shih Chang Chang, Bhadrinarayana Lalgudi Visweswaran, Jae Won Choi, Kyounghwan Kim

Patent number: 12154480Abstract: 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: GrantFiled: March 15, 2023Date of Patent: November 26, 2024Assignee: Apple Inc.Inventors: 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: 12052891Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To mitigate diffraction artifacts, a first sensor (13-1) may sense light through a first pixel removal region having transparent windows arranged according to a first pattern. A second sensor (13-2) may sense light through a second pixel removal region having transparent windows arranged according to a second pattern that is different than the first pattern. The first and second patterns of the transparent windows may result in the first and second sensors having different diffraction artifacts. Therefore, an image from the first sensor may be corrected for diffraction artifacts based on an image from the second sensor.Type: GrantFiled: July 7, 2021Date of Patent: July 30, 2024Assignee: Apple Inc.Inventors: Yuchi Che, Abbas Jamshidi Roudbari, Jean-Pierre S.

Patent number: 12019835Abstract: Visibility of the metal mesh touch electrodes can be mitigated using one or more mitigation techniques. In some examples, the boundary between touch electrodes and/or the boundary between a touch electrode and a routing trace of another touch electrode and/or the boundary between two routing traces can be non-linear. In some examples, dummy cuts can be made within an area of a touch electrode region (e.g., while maintaining the same electrical potential for the touch electrode region). In some examples, notches can be made in the metal mesh. In some examples, the location of cuts and/or notches can be optimized to mitigate visibility of the metal mesh. In some examples, some or all of the visibility mitigations may be used in combination in a touch screen.Type: GrantFiled: June 15, 2022Date of Patent: June 25, 2024Assignee: Apple Inc.Inventors: Tiffany Tang Moy, Tsung-Ting Tsai, Warren S.
