Abstract
A pixel module for use in a large-area display has a cluster of sequentially interconnected similar pixel modules that are driven by a central controller. The module includes pixel elements that have a serial video data bus input, and command input lines that are electrically connected to inputs of a latch. The latch has parallel inputs and outputs which are clocked with a data dock input. Also included are a current driver device for driving the pixels, a first inverter for driving the data clock input, an address input connected to a second inverter, an EEPROM connected to the input port, and a power supply.
