Abstract
A display device has row driver circuitry ( ) providing row address signals and column address circuitry ( ) providing pixel drive signals. The row address signals comprise a plurality of voltage levels (V -V ) to implement a desired drive scheme. The column address circuitry comprises circuitry ( ) for generating low voltage representations of at least some of the row address signals. The row address circuitry comprises a conversion circuit ( ) for converting the representations into the row address signal levels, at least one of has a high voltage magnitude. The invention provides an architecture which partitions different sections of the row voltage supply circuitry optimally between the row and column drivers. This enables a simplified power supply to be provided which can be made more power efficient.
