subject: Wobulation [print this page] Also, the image overlap inherent in the use of wobulation eliminates the 'screen door' effect common on other fixed pixel displays such as plasma and LCD, but may in some implementations also create some reduction in sharpness. Wobulation is used by a number of TV manufacturers, including Hewlett-Packard, Mitsubishi, RCA, Samsung, and Toshiba. As of 2007[update], wobulation is used only to double the horizontal resolution of a display, unlike CRT interlacing that doubles the vertical resolution. However, wobulation is currently capable of doubling the vertical and horizontal resolution of an image (2x wobulation). Wobulation technology used in TVs is becoming obsolete, as manufacturers shift away from producing rear projection TVs. References U.S. Patents 6,078,038; 7,030,894 and 7,034,811.
