Abstract
In a dot-matrix type vehicle condition display apparatus, binary coded signals corresponding to items to be displayed on a dot-matrix type fluorescent display tube are applied to portions of address input terminals of a memory, while binary coded signals corresponding to ordinal numbers of character columns of the items to be displayed are applied to other address input terminals of the memory. The memory produces a binary coded output corresponding to a character determined by signals at those address input terminals. The binary coded output of the memory is fed to a character generator, which in turn sequentially supplies signals corresponding to the respective column dots of that character to row drivers, which in turn cooperates with column drivers to dynamically scan the fluorescent display tube. The items displayed on the fluorescent display tube is moved or stopped in response to the actuation or deactuation of a start/stop switch.
