Patent number: 11740953Abstract: This document describes techniques and apparatuses including a solder joint damage-prevention mode for a computing device. In general, the computing device may enter the solder joint damage-prevention mode to transfer heat to solder joints and prevent failure mechanisms such as fracture, creep, and/or fatigue. The solder joint damage-prevention mode may rely upon one or more operations, including identifying a state of the computing device in or following which damage to the solder joints has an increased likelihood and, in response, activating a thermal-conditioning system. The thermal-conditioning system may, in general, increase a temperature of the solder joints to improve mechanical robustness of the solder joints.Type: GrantFiled: May 10, 2021Date of Patent: August 29, 2023Assignee: Google LLCInventors: Luke Manuel Brantingham, Kavinaath Murugan, Yun Sun Lee, Aaditya Kandibanda

Patent number: 11380260Abstract: An electronic device comprises a controller. The controller is configured to provide a first signal to a display of the electronic device to turn off the display. The controller is also configured to provide a second signal to the display to alter a gate source voltage of a drive transistor coupled to a light emitting diode (LED) of a pixel of the display while the display is turned off.Type: GrantFiled: March 27, 2018Date of Patent: July 5, 2022Assignee: Apple Inc.Inventors: Junhua Tan, Kingsuk Brahma, Jie Won Ryu, Shengkui Gao, Shiping Shen, Majid Gharghi, Hyunwoo Nho, Injae Hwang, Kavinaath Murugan, Sun-Il Chang, Chin-Wei Lin, Hyunsoo Kim, Rui Zhang, Jesse Aaron Richmond, Yun Wang, Hung Sheng Lin

Patent number: 11380231Abstract: Electronic devices and methods for compensating for aging or other effects in a display during a non-transmitting state (off state) of the display. Sensing may include emissive element sensing of the display and/or thin film transistor sensing of the display. Compensating for the effects may preserve or increase a uniformity of transmission of the display.Type: GrantFiled: August 31, 2018Date of Patent: July 5, 2022Assignee: Apple Inc.Inventors: Chin-Wei Lin, Hung Sheng Lin, Hyunsoo Kim, Hyunwoo Nho, Injae Hwang, Jesse A. Richmond, Jie Won Ryu, Junhua Tan, Kavinaath Murugan, Kingsuk Brahma, Shengkui Gao, Shiping Shen, Sun-Il Chang, Myung-Je Cho, Yafei Bi, Myungjoon Choi, Weichuan Yao, Chaohao Wang

Patent number: 10950182Abstract: The present disclosure relates generally to systems and methods that may reduce a reduction in visual artifacts related to hysteresis of a light emitting diode (LED) electronic display. In one example, an electronic device may include a controller. The controller is may provide a signal to a pixel of a display of the electronic device while at least a portion of the display is turned off. The signal may include a first current and a second current. The first current may be designed to increase an ambient temperature corresponding to the pixel. The second current may be generated as part of an active panel conditioning operation. By applying the first current and the second current, hysteresis settling times from the pixel may improve, therefore improving speeds of sensing and compensation operations of the electronic device.Type: GrantFiled: September 11, 2019Date of Patent: March 16, 2021Assignee: Apple Inc.Inventors: Junhua Tan, Kingsuk Brahma, Jie Won Ryu, Shengkui Gao, Shiping Shen, Majid Gharghi, Hyunwoo Nho, Injae Hwang, Kavinaath Murugan, Sun-Il Chang, Chin-Wei Lin, Hyunsoo Kim, Rui Zhang, Jesse Aaron Richmond, Yun Wang, Hung Sheng Lin, Alex H.

Publication number: 20180075798Abstract: A mobile electronic device includes a display having a pixel and processing circuitry separate from but communicatively coupled to the display. The processing circuitry prepares image data to send to the pixel and adjusts the image data to compensate for operational variations of the display based on feedback received from the display that describes a present operational behavior of the pixel. The mobile electronic device also includes additional electronic components that affect the present operational behavior of the pixel depending on present operational behavior of the additional electronic components.Type: ApplicationFiled: July 27, 2017Publication date: March 15, 2018Inventors: Hyunwoo Nho, Hung Sheng Lin, Jie Won Ryu, Junhua Tan, Sun-Il Chang, Shengkui Gao, Rui Zhang, Injae Hwang, Kingsuk Brahma, Jesse Aaron Richmond, Shiping Shen, Hyunsoo Kim, Sebastian Knitter, Lu Zhang, Nicolas P.
