  • Patent number: 10726811
    Abstract: An electronic device may have a display such as an organic light-emitting diode display. Electronic devices may also include a number of sensors such as accelerometers and gaze detection sensors. A graphics processing unit (GPU) may render digital pixel values for pixels in the device display. Frames (F2) with long rendering times may cause latency. To reduce latency, an image frame may be displayed for an extended period of time (68) to wait for the subsequent frame (F2) to finish rendering. Once the subsequent image frame (F2) has finished rendering, the subsequent image frame may be displayed without delay. To increase the lifespan of the display, variable persistence may be used. Sensor data and other factors may be used to dynamically determine persistence for minimal motion blur and maximum display lifespan. Sensor data may also be used to determine refresh rates for different portions of the display.

  • Patent number: 10234902
    Abstract: A reconfigurable touch screen computing device with folding configurations and an alignment locking mechanism. The touch screen display is made up of segments coupled to a flexible circuit and can be reconfigured from a compact state to an expanded state. The form factor of the compact state is roughly the size of a typical handheld phone, with an integrated speaker and microphone. The form factor of the expanded state is roughly the size of a tablet computer which may also include the mechanical functionality of a laptop. Both states provide a configuration which includes a touch screen display on a front side and a protective housing on a back side. The computing device may further include sensors to indicate the state of configuration. In one embodiment, a module attached to, situated within, or otherwise associated with at least one segment may contain all or substantially all processing and memory, along with a communications system, all of which may be used in either state.
