Patent number: 11756505Abstract: Systems, methods, and devices are provided for providing intra-frame luminance scaling to avoid drawing excessive power while still providing exceptional brightness. An instantaneous average pixel luminance of an electronic display may be determined. The instantaneous average pixel luminance may correspond to an amount of light currently being emitted by the electronic display due to a previous image frame and a current image frame. Based at least in part on the instantaneous average pixel luminance, the luminance of a subset of pixels of image data of the current image frame may be adjusted, thereby allowing the electronic display to operate at a relatively high brightness level without exceeding a power limit.Type: GrantFiled: March 30, 2021Date of Patent: September 12, 2023Assignee: Apple Inc.Inventors: Yang Xu, Jie Won Ryu, Kingsuk Brahma, Koorosh Aflatooni, Marc Joseph DeVincentis, Mohammad Ali Jangda, Paolo Sacchetto, Shengkui Gao, Sinan Alousi, Yafei Bi, Chun Lu

Patent number: 11740736Abstract: Techniques for implementing and/or operating an electronic device including a display pixel layer, which writes a display image during an active period and continues displaying the display image during a blanking period, and a touch sense layer, which generates a first touch image during the active period and a second touch image during the blanking period. The electronic device further includes a controller that determines a first noise metric indicative of display-to-touch noise resulting during the active period based on the first touch image, determines a second noise metric indicative of display-to-touch noise resulting during the blanking period based on the second touch image, and instructs the touch sense layer to not generate a third touch image during a subsequent active period in response to the first noise metric being greater than a noise threshold and the second noise metric not being greater than the noise threshold.Type: GrantFiled: June 10, 2019Date of Patent: August 29, 2023Assignee: Apple Inc.Inventors: Anshi Liang, He Yi, Yang Xu, Paolo Sacchetto, Jun Li, Jingyu Huang, Marc Joseph DeVincentis, Yue Jack Chu

Patent number: 11302264Abstract: A display device may include rows of pixels that display image data on a display and a circuit. The circuit may receive pixel data value of image data for a pixel in a first row of the rows of pixels, determine a weight factor to apply to the pixel data value based on a position of the first row with respect to the other rows, such that each row is associated with a current-resistance (IR) drop across the display. The weight factor is determined based on a respective IR drop associated with the first row. The circuit may also generate a weighted pixel data value based on the weight factor and the pixel data value and send the weighted pixel data value to a display driver circuit that renders the image data via the display.Type: GrantFiled: July 12, 2019Date of Patent: April 12, 2022Assignee: Apple Inc.Inventors: Shengkui Gao, Marc Joseph DeVincentis, Yue Jack Chu, Sinan Alousi, Mohammad Hajirostam, Mohammad Ali Jangda, Koorosh Aflatooni, Pierre-Yves Emelie, Yafei Bi, Paolo Sacchetto, Kasra Omid-Zohoor

Publication number: 20210304673Abstract: A system may include an electronic display panel having pixels, where each pixel may emit light based on a respective programming signal. The system may include a memory storing a map. The processing circuitry may determine a function for each pixel from the map. The processing circuitry may determine a respective control signal based on the function and a target brightness level for each pixel to generate multiple control signals, where the respective control signal is used to generate the respective programing signal for each pixel. The processing circuitry may determine a scaling factor based at least in part on the first map and may scale at least a subset of the multiple control signals based at least in part on the scaling factor.Type: ApplicationFiled: March 3, 2021Publication date: September 30, 2021Inventors: Shengkui Gao, Haifeng Li, Sinan Alousi, Marc Joseph DeVincentis, Yafei Bi, Hung Sheng Lin, Yi Qiao, Paolo Sacchetto, Weijun Yao, Pierre-Yves Emelie, Maofeng Yang, Yue Jack Chu

Patent number: 10573265Abstract: Electronic devices, storage medium containing instructions, and methods pertain to cancelling noise that results from application of clocks/clock drivers of a display. The electronic display may inject counter noise into the cathode. For example, the counter noise may be injected via a sensing layer, via unused clocks, and/or via a power rail of the display.Type: GrantFiled: August 23, 2018Date of Patent: February 25, 2020Assignee: Apple Inc.Inventors: Mohammad Ali Jangda, Marc Joseph DeVincentis, Abbas Jamshidi-Roudbari, Warren S.

Publication number: 20200004378Abstract: Display-to-touch noise may be perceptible when a touch image generated during an active period of an electronic display of an electronic device is used to determine a touch indication on the display. The electronic device may include a display pixel layer including a plurality of display pixels that write display images to the display during a display active period and continue displaying the display image during a display blanking period. The electronic device may also include a touch sense layer including a plurality of touch sense pixels that facilitate generation of a first touch image during a first display active period and generation of a second touch image during a first display blanking period. The electronic device may further include a controller coupled to the display pixel layer and the touch sense layer that facilitates the reduction or elimination of display-to-touch interference.Type: ApplicationFiled: June 10, 2019Publication date: January 2, 2020Inventors: Anshi Liang, He Yi, Yang Xu, Paolo Sacchetto, Jun Li, Jingyu Huang, Marc Joseph DeVincentis, Yue Jack Chu

Patent number: 10134349Abstract: Aspects of the subject technology relate to electronic devices with displays. A display may include an array of display pixels and control circuitry for operating the display. In some scenarios, interference signals from other components of the electronic device or additional external devices can couple to the control circuitry for the display and cause distortions in displayed data. Display frames may be displayed by an electronic device display with a varying phase. The varying phase display frames may each include a distortion pattern that also varies from frame to frame due to the varying phase. The varying distortion patterns may average out or visibly cancel when viewed by a user such that no visible artifact of the interference signal is seen by the user. The varying phase can be actively tuned to the interference signal if desired.Type: GrantFiled: April 26, 2017Date of Patent: November 20, 2018Assignee: Apple Inc.Inventors: Rui Zhang, Guangmao Xing, Paolo Sacchetto, Marc Joseph Devincentis, Anshi Liang, Weijun Yao, Sang Y.
