  • Patent number: 7034780
    Abstract: A plasma display device is provided which is capable of preventing image disturbance and imposition of excessive loads even when resolution is switched. A vertical frequency counter counts vertical sync signals using system clocks and a vertical frequency comparator checks whether or not the value obtained from the counting matches up with a vertical frequency decoded value. A line number counter counts vertical sync signals using horizontal sync signals and a line number comparator checks whether or not the value obtained from the counting matches up with a line number decoded value. A dot number counter counts horizontal sync signals using analog digital clocks and a dot number comparator checks whether or not the value obtained from the counting matches up with a dot number decoded value. These values are ORed by an OR circuit and the result is output in a form of a mode monitoring detection signal.

  • Patent number: 5905282
    Abstract: A multi-terminal surge protection device able to absorb surges of either polarity between lines and between a line and ground, in which the difference in operating time between the device elements connected to lines is reduced. A plurality of unipolar surge protection device elements are used which only operate to absorb surges of a specific polarity, and do not exhibit a reverse withstand characteristic upon application of a reverse-polarity voltage. One element is connected to a first line and another element to a second line, while a different element is connected to ground. A semiconductor substrate and second electrode are used that are common to all elements. To prevent lateral interference between elements, at least the element connected to ground is isolated from the line elements.
