The 1.9-inch Super-LTPO panel on the Rio IPTD999 is a visual treat. "LTPO" (Low-Temperature Polycrystalline Oxide) allows the refresh rate to dynamically scale from 1Hz (always-on display mode) to 60Hz (interaction mode). This fluidity is immediately apparent when scrolling through the tile-based menu system. Note: If you were looking for the paper
