Method for driving electro-optic displays
First Claim
1. A method of driving a large area display comprising a plurality of sub-units arranged in a plurality of rows and columns of sub-units, each sub-unit having an associated pixel row driver and an associated pixel column driver, the sub-units within each column of subunits being interconnected such that the associated pixel column drivers drive the pixel column electrodes of all the sub-units within the column of subunits such that the plurality of sub-units of the large area display are driven as a single display, the method comprising:
- sequentially providing a separate chip select signal to each pixel row driver associated with a row of sub-units,sequentially supplying data to the drivers of each row of pixels in the row of sub-units for which the associated row driver has received the chip select signal so that only the drivers of the rows of pixels within a single row of sub-units are supplied data at any one time,supplying column data to a first shift register of a first column driver as a series of column data values under the control of a Gate Start Pulse signal, andsupplying the column data to a second shift register of a second column driver as a series of column data values under the control of a delayed Gate Start Pulse signal.

Abstract
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.
