Abstract: The invention relates to a circuit array for operating a liquid-crystal display in the time-division multiplexing mode, the display having at least one backplane and several segments. The circuit array includes a microprocessor having a first pulse generator, a shift register array storing data signals supplied to the circuit array, this shift register array having a number of stages corresponding to the number of segments, and driving stages which generate segment pulse sequences for the segments in accordance with the supplied data signals. In accordance with the invention, the microprocessor supplies the data signals to the shift register array via a first interface, the shift register array being designed as a cyclic shift register with each register point of the shift register array being clearly allocated to a segment. In addition, the microprocessor supplies control data, particularly data determining the time multiplexing rate, to a second interface having a decoder.
