Abstract
A device, and a corresponding method for its operation, for converting binary electrical signals into optical form and for scrolling the optical signals across an array of liquid crystal cells. The device in its two-dimensional form includes an array of rows of liquid crystal cells of the ferroelectric smectic type, input circuits for applying binary signals to an input cell in each row, and a three-phase clocking circuit connected to the remaining cells in each row, to propagate the states of the input cells rapidly into successive cells across the array, in the same manner as a shift register, but with the signals being stored in optical form for ease of processing in optical processing apparatus.
