Abstract (en)
[origin: WO8605305A1] Programmable circuit for the control of a liquid crystal indicator (LCD controller), with intermediate drive stages as required, for two BUS patterns, of which one serves for data exchange with a computer, through the other there is data exchange with at least one addressable memory, allocated to the LCD. Both BUS patterns, consisting of address, data and control lines, are developed as complete and parallel BUS patterns, which under a given state of connections of the control circuit and, as the case may be, in response to an appropriate additional signal from the computer, are connected together in such a way as to permit an exchange of data between the memory connected to the LCD and the computer.
