  • Method and apparatus for controlling a dynamic or static type digital display device
    Patent number: 4424513
    Abstract: A control apparatus for driving a digital display device of either a dynamic or static type is responsive to data from a switch indicating whether a dynamic or static type display device is to be driven. When a dynamic display device is to be driven, corresponding instruction data are read out from a first memory included in the control apparatus whereas when a static display device is to be driven, corresponding instruction data are read out from a second memory. A processing circuit operates in accordance with selected instruction data, and thus (a) time shared output signals indicative of data to be displayed are generated through a plurality of output terminals for driving the dynamic display device, or (b) a single output indicative of data to be displayed is generated through one of the output terminals so as to drive the static display device.
