Image Number 3 for United States Patent #6876349.

Digital to analogue conversion in an AMLCD is obtained by using the column electrode capacitance as part of the digital to analogue conversion circuit by dividing columns (19) into separate sections and serially performing the conversion via switching elements (31). Alternative embodiments comprise a column driver circuit with capacitors having a (binary) divided range of capacitance or use column sub-electrodes of different widths.
