Abstract: A method and apparatus for driving a plurality of addressable elements consist of driving and selectively enabling one or more addressable elements arranged as an M×N array using two drivers. A first and a second driver are used to drive first and second signals at slightly different frequencies on a first and a second display conductor. A plurality of pixels, coupled between the first and second display conductors, is addressed according to a pixel location in which the first signal is approximately in phase with the second signal. The pixel scan rate is proportional to the difference between the first and second signal frequencies. The first and second conductors may contain a plurality of delay elements and tap-off points. Conducting lines may be terminated by their characteristic impedance to prevent any reflection of the traveling signals.

Abstract: A method and apparatus for driving a plurality of addressable elements consist of driving and selectively enabling one or more addressable elements arranged as an M×N array using two drivers. The columns may be addressed in parallel. Columns may be coupled to a conductor by a charge transfer/isolation circuit. A voltage waveform or pulse train may be propagated down the display conductor such that a pulse is present on the display conductor for each element of a row of elements to be addressed. When the beginning of the pulse train has propagated to the last column tap-off point so that a different pulse is present at each column tap-off point corresponding to the row of elements to be selected, a corresponding charge is transferred to each column conductor in parallel. Thus, a voltage is supplied to select each element on the selected row as determined by the state of the pulse train at each column tap-off point.
