Abstract
A large area display comprises multiple sub-units arranged in rows and columns. Each sub-unit has associated row and column drivers, with the column driver driving the column electrodes of all the sub-units a column. A chip select means provides a separate chip select signal to each row of sub-units, so that only one row of sub-units are scanned at a time, and all the sub-units in the selected row are scanned simultaneously. Column data are supplied to the column drivers as a linear series of column data values; and delayed Gate Start Pulse signals are fed to the column drivers in each column of sub-units after the first so that these column drivers receive the delayed Gate Start Pulse signals and apply the appropriate column data values to their associated column electrodes.
