<p>The opto-electronic matrix display panel uses row and column addressing of electric field responsive cells, for example liquid crystal cells, and uses latching memory outputs to drive the rows and columns. Parallel input/output drivers are used rather than the conventional serial to parallel converter type drivers, improving the speed of transferring data to the display. The driver registers have a reset input passivating the circuit, with each reset signal derived from an address decoder, permitting one register at a time to be driven by the data bus of the microprocessor Each line of the data bus is connected to an input of each register. Row and column electrodes are connected directly to the register outputs and are latched as data is cyclically transferred to the driver registers.</p> |
