摘要： 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 MxN 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. The matrix display pixels are selectively enabled by modulating an amplitude of the first signal and/or an amplitude of the second signal when the selected pixel location(s) is addressed so that the voltage differential between the first and second signals is sufficient to enable the addressed pixel.
