Middle-out technique for refreshing a display with low latency

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.
