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.
Picture display device comprising a plurality of electron transport ducts or transporting electrons in the form of electron currents, and selection electrodes for withdrawing each electron current at predetermined locations from its transport duct and for directing said current towards a luminescent screen. The selection electrodes are driven by a selection driver comprising integrated driver circuits having outputs which are DC-coupled to the selection electrodes and are cascaded as regards their power supply voltages in such a way that they apply both selection pulses and transport (bias) voltage to the selection electrodes.
A display system for a vehicle utilizing two vehicle operating parameters as input signals on axes of a different direction on a display surface. The position on the display surface designated by the two signals is displayed.
There is disclosed a display control device having plural memories for storing information, an address unit for generating an address signal to select one of said plural memories, said address unit comprising an address memory for storing said address signal, an output device connected to said address unit and adapted to read said information from one of said plural memories in response to said address signal stored in said address memory, and a display connected to said output device for displaying said information supplied by said output device. None of said memories stores an alarm message which is displayed during overflow, for example.
An automotive vehicle includes a plurality of indicators for indicating operating states of components of a system. A method of inducating fault or no-fault condition of the components derived from different possible causes, comprises causing the indicators to be placed into one of two different indicating statuses, to indicate by the combination statuses of the indicators the conditions of the components.
A display device 10 consisting of five cells of seven segments each, is used in a photocopying machine in order to indicate normal operation and certain abnormal situations. The latter are indicated by means of messages in plain language, represented by cyclically moving characters. The messages are stored permanently in an EPROM 50, from which they are extracted as required under the command of a CPU 80 in relation to the corresponding type of abnormality, as detected by a set of sensors 82, 84, 86. A suitable subroutine causes the letters of message to slide along the cells of the display device 10 from right to left.
