A technology from HP that increases the native resolution of front and rear-projection TVs. For example, Wobulation can generate a 1920x1080 resolution using a 1280x1024 DLP chip. It creates subframes out of each frame and uses a shifting mechanism to offset one subframe by a partial pixel. Subframes are displayed one after the other so rapidly that they blend together as if they were displayed at once. See
DLP.
