  • Patent number: 10678403
    Abstract: A computing device runs multiple activities concurrently and provides at least two modes for interacting with the activities. The user may toggle between the modes as desired. In a full-screen mode, one activity occupies substantially an entire display screen. In a windowed mode, the activity is visible within a window, and a portion of at least one other window is also visible. In the windowed mode, the user can cause windows to move, thereby changing focus from one activity to another. For example, the window having focus can be moved off the screen, to be replaced by a new window that is then given focus. The windows are ordered in a sequence and move in concert with one another; pushing one window off one edge of the screen causes a new window to appear at the opposite edge. A persistent positional relationship can be established among windows.

  • Patent number: 10564774
    Abstract: Methods for mitigation of sensing error effects in display panels are disclosed. Display panels, such as pixel-based panels, may have circuitry to sense the luminance values, compare measurements with target luminance values, and provide corrections. Sensing errors, such as ones caused by sensor hysteresis and thermal fluctuations, may lead to overcorrections and visible artifacts. Mitigations schemes discussed herein include filtering of sensed signal with low pass filters, partial correction strategies, and feedforward sensing schemes. Circuitry that implements these schemes are also discussed.

  • Patent number: 10553164
    Abstract: A system for calibrating a liquid crystal display (LCD) includes a plurality of temperature sensors, a storage medium, and a controller. Each temperature sensor measures a current temperature of at least one pixel in the LCD. The storage medium stores information about latencies for any LC-based pixel, wherein each latency corresponds to a time period for transition from a starting to an ending illumination state for one temperature of the LC-based pixel. The controller determines, based on the current temperature, the transition information and frame information, a time for each pixel in at least a portion of the LCD to transition from a first to a second illumination state. The controller computes, based on transition times, an LC transition time for at least the portion of the LCD and performs calibration of at least the portion of the LCD based on the LC transition time.

  • Patent number: 10520359
    Abstract: A terminal and a method for detecting luminance of ambient light, where the terminal includes a processor, an ambient light sensor, and a screen. The ambient light sensor and the screen are both coupled to the processor. A light-sensitive element of the ambient light sensor faces the screen and is located on a lower surface of the screen. After the screen is lit up, the processor adjusts first luminance of the screen to a value below a first threshold within a visual persistence time of human eyes. The ambient light sensor detects luminance of first ambient light of the terminal within the visual persistence time of human eyes. The terminal may eliminate non-ambient light that enters the ambient light sensor such that the ambient light sensor may detect luminance of relatively real ambient light.
