    Patent number: 11030968
    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.

  • Anti-glare and anti-reflective tactile effect surface for optical touch detection
    Patent number: 10996795
    Abstract: An optical touch-sensitive device includes a touch-sensitive surface over which touch events are detectable. The device also includes surface features on the surface that reduce touch object friction relative to an absence of surface features. Emitter and detectors are arranged along a periphery of the touch-sensitive surface. The emitters can produce optical beams that travel across the touch-sensitive surface to the detectors. Touches on the touch-sensitive surface disturb the optical beams and the touch-sensitive device determines touch events based on the disturbed optical beams. The surface features may also be arranged to reduce glare by diffusing light. In some embodiments, an anti-reflective layer is on top of the touch-sensitive surface and the surface features.
