  • Publication number: 20200243033
    Abstract: In various examples, images rendered by a processor—such as a graphics processing unit (GPU)—may be scanned out of memory in a middle-out scan order. Various architectures for liquid crystal displays (LCDs) may be implemented to support middle-out scanning, such as dual-panel architectures, ping-pong architectures, and architectures that support both top-down scan order and middle-out scan order. As a result, display latency within the system may be reduced, thereby increasing performance of the system—especially for high-performance applications such as gaming.

  • Publication number: 20190266959
    Abstract: A display device includes an array of LEDs, an array of LCD pixels, and a display controller. The display controller is configured to compensate for one or more sources of color variation in light produced by the LEDs. The display controller can determine a first color variation at a given LCD pixel based on the distance between the given LCD pixel and one or more LEDs. The display controller can also determine a second color variation at the given LCD pixel based on a current level supplied to the one or more LEDs. The display controller configures the given LCD pixel to filter light that is received from the one or more LEDs in a manner that reduces or eliminates either or both of the first and second color variations.

  • Patent number: 10395432
    Abstract: In embodiments of the invention, a method may include displaying an array of slits using a first light-attenuating spatial light modulator, displaying a pre-filtered image using a second light-attenuating SLM by attenuating rays of light originating from a surrounding environment to synthesis a near-eye light field, where the rays of light pass through the first and second light-attenuating SLMs, and selectively blocking the rays of light originating from the surrounding environment using the array of slits to generate a virtual image in said near-eye light field.

  • Patent number: 9830871
    Abstract: A method for driving a display panel having a variable refresh rate is disclosed. The method comprises detecting a condition that results in a charge accumulation in the display panel using an accumulated difference in time duration between frames of positive polarity and frames of negative polarity received from an image source. The DC imbalance is a result of a frame pattern comprising alternating frames of differing polarities, wherein frames of positive polarity within the frame pattern are of a different time duration than frames of negative polarity, and wherein the frame pattern results in an accumulation of charge in pixels of the display panel. The method also comprises correcting for the charge accumulation by disrupting the frame pattern.

  • Patent number: 9773460
    Abstract: A system, method, and computer program product are provided for combining low motion blur and variable refresh rate in a display. In one embodiment, a hold-type display is operated in a first mode of operation where the hold-type display is dynamically refreshed such that the hold type display handles updates to image frames at unpredictable times and where for each of the image frames a backlight of the hold-type display is activated for an entire duration of display of the image frame. Additionally, it is determined that at least one predefined condition has been met. Further, in response to the determination, the hold-type display is operated in a second mode of operation where the hold-type display is statically refreshed such that the hold-type display handles updates to image frames at regular intervals and where for each of the image frames the backlight of the hold-type display is flashed.
