`(57) Abstract: A column driving circuit and method for driv-
`ing pixels in a column row matrix. Specifically, the present in-
`vention provides a circuit and method that generally includes an
`input for receiving a signal, a multiplexing circuit for receiving
`the signal from the input, and a first and a second column linc,
`wherein each column line alternates in receiving the signal from
`the multiplexing circuit. By splitting the signal between two col-
`umn lines, overall line capacitance is reduced, as are problems
`associated with delays in ramp retrace.
