Patent Images
1. An apparatus for driving a display, the apparatus comprising,a first voltage supply line configured to supply a first voltage;
- a second voltage supply line configured to supply a second voltage;
one or more drive lines configured to supply a driving voltage waveform;
a waveform generator configured to generate the driving voltage waveform on the one or more drive lines;
a first switch configured to selectively couple a first one of a plurality of rows or columns to the first voltage supply line;
a second switch configured to selectively couple the first one of the rows or columns to the second voltage supply line; and
a third switch configured to selectively couple the first one of the rows or columns to a first drive line of the one or more drive lines.

Abstract
An apparatus and method for driving a display a display. Two switches for each common line are used to couple the common line to a respective first and second hold voltage supply lines. A third switch for each common line is used to couple the common line to a drive line. A waveform generator is used to generate the driving waveform on the drive line.
