  • Patent number: 10345388
    Abstract: A method for screening a lithium ion battery is provided. A number of lithium ion batteries are galvanostatically discharged a to an inflection point voltage at an inflection point of a discharge curve at a first constant current I1. The number of lithium ion batteries are rested for a first rest time T1 to raise an open circuit voltage of the number of lithium ion batteries to U1. U1 is greater than the inflection point voltage. The number of lithium ion batteries are galvanostatically discharged to the inflection point voltage at a second constant current I2, in which I2<<I1. The number of lithium ion batteries are rested for a second rest time T2 and the batteries are screened based on a self-discharge of the number of lithium ion batteries.

  • Publication number: 20190189086
    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.

  • Publication number: 20190180669
    Abstract: An electronic device that includes processing circuitry configured to generate a frame of image data that has a frame duration is provided. The electronic device includes a display that has a plurality of pixels. Each of the plurality of pixels displays image data from the frame of image data for a pixel emission period that is less than the frame duration. A first pixel of a column of pixels of the plurality of pixels begins displaying the image data from the frame of image data at a first time for a first duration. A second pixel of the column of pixels that is adjacent to the first pixel begins displaying the image data from the frame of image data at a second time for a second duration. The first and second durations are equal to the pixel emission period. The second time begins after the first duration of time.

  • Publication number: 20190180672
    Abstract: An electronic device may have a display and a gaze tracking system. The electronic device may display images on the display that have a higher resolution in a portion of the display that overlaps a gaze location than other portions of the display. Timing controller circuitry and column driver circuitry may include interpolation and filter circuitry. The interpolation and filter circuitry may be used to perform nearest neighbor interpolation and two-dimensional spatial filtering on low resolution image data. Display driver circuitry may be configured to load higher resolution data into selected portions of a display. The display driver circuitry may include low and high resolution image data buffers and configurable row driver circuitry. Block enable transistors may be included in a display to allow selected blocks of pixels to be loaded with high resolution image data.

  • Patent number: 10319279
    Abstract: This application relates to performing certain dithering processes to eliminate display artifacts such as flicker, which can be caused by charge accumulation at the display. The dither process can be performed by a display controller that uses a group lookup method for identifying groups of dithering patterns that can be combined to expand a number of color values available to the display. The dither process can also be performed as a temporal process that incorporates groups of dithering patterns into frames and shifts a spatial arrangement of the groups of dithering patterns over a sequence of frames. Additionally, the dither process can incorporate counters that count the number of times a particular spatial arrangement of dithering patterns has been used in a sequence of frames in order that each spatial arrangement of dithering patterns will share an average count with other spatial arrangements over a sequence of frames.

  • Patent number: 10216038
    Abstract: The present invention relates to the display technology field, and provides a backplate, a plastic-iron integrated structure, a backlight unit, and a display device. The backplate is provided with a first through hole, and the first through hole has an inner wall and an outer wall which form a projection structure on the backplate. When the backplate is bonded with a plastic frame to form the plastic-iron integrated structure, the plastic frame not only contacts the inner wall of the first through hole, but also contacts the surface of the projection structure, thus increasing the contact area between the plastic frame and the backplate, and increasing the bonding force between the plastic frame and the backplate. Even when the plastic frame shrinks in case of fluctuations in temperature and/or humidity, the plastic frame is not easily separated from the backplate, and the stability of the formed plastic-iron integrated structure is improved.
