Abstract: This application relates to methods and apparatus to refresh a display device at various frequencies. Specifically, multiple areas of the display device may be refreshed concurrently at different frequencies. In this way, when static content is being displayed in certain areas of the display device, those certain areas can be refreshed at a lower rate than areas displaying dynamic content such as video or animation. By refreshing at lower rates, the energy consumed by the display device and subsystems associated with the display device can be reduced. Additionally, processes for reducing flicker when refreshing the display device at different refresh rates are disclosed herein.

Abstract: 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.

Abstract: A touch screen is disclosed. A plurality of common electrodes can be configured to operate as display circuitry during a display phase, and to operate as touch sensing circuitry during a touch sensing phase. The plurality of common electrodes can include a first common electrode associated with a first display pixel, and a second common electrode associated with a second display pixel. Circuitry can be configured to update the first display pixel at a first time while driving the first common electrode but not the second common electrode, and update the second display pixel at a second time, after the first time, while driving the second common electrode but not the first common electrode. In some examples, the circuitry can be configured to leave the second common electrode floating while driving the first common electrode, and leave the first common electrode floating while driving the second common electrode.

Abstract: The disclosure describes procedures for dynamically employing a variable refresh rate at an LCD display of a consumer electronic device, such as a laptop computer, a tablet computer, a mobile phone, or a music player device. In some configurations, the consumer electronic device can include a host system portion, having one or more processors and a display system portion, having a timing controller, a buffer circuit, a display driver, and a display panel. The display system can receive image data and image control data from a GPU of the host system, evaluate the received image control data to determine a reduced refresh rate (RRR) for employing at the display panel, and then transition to the RRR, whenever practicable, to conserve power. In some scenarios, the transition to the RRR can be a transition from a LRR of 50 hertz or above to a RRR of 40 hertz or below.

Abstract: This application sets forth systems, methods, and apparatus for improving charge settling times for lines and pixels of a display panel. The charge settling times are improved by providing an over drive signal and a bias current to a line and/or pixel of the display panel based a comparison of content data to be output by the display panel. In this way, by initially charging the line and/or pixel with the over drive signal, the line and/or pixel can be fully charged more quickly in display panels that operate at higher refresh rates.
