Abstract:
A process for generating data to switch a display light driver for a large video display electronic sign system comprising the steps of:a. generating first data signals and clock signal by a data distributor output board; b. receiving said data signals and clock signal by a line controller; c. storing the signals of data and clock in RAM on the data distributor output board; d. generating second data and clock signals, and latch signals on the data distributor output board; e. receiving the data and clock signals by a display module for turning display light drivers on or off in a large video display electronic sign, whereby a data distributor sends the first data and clock signals to a column director; f. generating an output enable signal by a line controller which output enable signal is sent to the display module for controlling intensity of a light driver; and, g. receiving configuration data at the data distributor, the configuration data coded in command bytes, the configuration data originating from a computer including, but not limited to, technology type and size of a display.
