Patent number: 11061793Abstract: Circuits, methods, and apparatus that may estimate the power being consumed by an OLED display screen of an electronic device, may provide further information about that power usage, may modify or change functions performed by the electronic device based on that power usage, and may inform an application's developer about the amount of power being used by the electronic device while the electronic device is running the application. One example may estimate the power being used by an OLED display screen of an electronic device by determining the content of images being displayed during a duration. The estimated power may then be presented to a user. The estimated power may be used in decisions to modify or change parameters of the screen or other device components.Type: GrantFiled: February 20, 2018Date of Patent: July 13, 2021Assignee: Apple Inc.Inventors: Abhinav Pathak, Conor J. O'Reilly, Shashi K. Dua, Udaykumar R. Raval, Christopher W. Chaney, Amit K. Vyas, Albert S. Liu, Roberto Alvarez, Rohit Mundra, Vladislav Sahnovich, Patrick Y. Law, Paul M. Thompson, Paolo Sacchetto, Chaohao Wang, Arthur L. Spence, Jean-Pierre Simon Guillou, Mohammad Ali Jangda, Christopher Edward Glazowski, Yifan Zhang, Prajakta S. Karandikar, Han Ming Ong

Patent number: 10467964Abstract: An electronic device comprises a display and a controller. The controller is configured to determine a change in a refresh rate of the display from a first frequency to a second frequency. The controller is also configured to selectively generate a control signal configured to control emission of a light emitting diode of a display pixel of the display based on the first frequency.Type: GrantFiled: February 11, 2016Date of Patent: November 5, 2019Assignee: Apple Inc.Inventors: Vasudha Gupta, Chin-Wei Lin, Yafei Bi, Hung Sheng Lin, Jean-Pierre Simon Guillou, Tsung-Ting Tsai, Sang Y.

Patent number: 9940879Abstract: The present disclosure generally relates to systems and techniques for calibrating displays to improve the white point uniformity between similar type devices. In one embodiment, a backlight includes multiple strings of LEDs, where each string is driven by a separate driver, or driver channel. Each string may be separately tested at a base current to determine its emitted chromaticity, and values indicative of the emitted chromaticities may be stored within the backlight as calibration values. The calibration values may then be used to determine the driving strength for each string that allows the display to produce the target white point when the light from the strings is mixed. Further, in certain embodiments, adjustments also may be made to the LCD panel based on the emitted chromaticities at the base current.Type: GrantFiled: October 5, 2011Date of Patent: April 10, 2018Assignee: APPLE INC.Inventors: Shawn Robert Gettemy, Joshua Grey Wurzel, Jean-Pierre Simon Guillou, Ming Xu, David Andrew Doyle
