Display Interfacing - Moving Beyond the Pixels

摘要

Today's MDDI and MIPI DSI have a long run ahead of them as they replace parallel CPU and RGB display interfaces. Their bandwidth capabilities match and exceed even the largest displays planned for use within handheld electronics, and their protocols support a variety of display types that allow cost, mass, and EMI-reduced systems to come to market. Yet, taking a look down the road at more integrated display subsystems with touch, advanced dynamic backlight controls, haptic feedback, ambient light, accelerometer, and proximity sensors require a fresh look at bandwidth and latency requirements. Full duplex interfaces - implemented as dual simplex data paths - completely remove these time restrictions and may be necessary for tomorrow's display subsystems.
