A large area display having multiple sub-units arranged in rows and columns and a method of driving the multiple sub-units as a single display are provided. Each sub-unit has an associated pixel row driver and pixel column driver. The large area display may also include a chip select means that provides a separate chip select signal to the pixel row driver of each row of sub-units, so that in the row of sub-units for which the associated row driver has received the chip select signal, only the rows of pixels within a single row of sub-units are supplied data at any one time. Column data and delayed Gate Start Pulse signals are fed to the pixel column drivers in each column of sub-units such that the appropriate column data values are supplied to the associated pixel column drivers.
