2.3 Display Board Wiring
The Display face consists of 4 rows by 6 columns of GB160818 Display Boards. Each Board
consists of an 8 high x 16 wide pixel matrix of ultra-bright red LEDs with each pixel consisting of a
single LED. This results is an overall matrix of 32 high by 96 wide Display. The Boards are driven in
a multiplex mode with the row anodes connected to the horizontal drive and the column cathodes
connected to the vertical drive. The Boards contain the display driver circuitry, which generates the
multiplexing signals for illuminating the LEDs.
Data enters the Board from the Logic Board on a 14-way screened Horizontal ribbon cable via an
IDC socket.
The 4-way Molex connector supplies 5 Volt Display Logic power and 15 Volt LED power to the
Board.
The Display Boards are fixed to stand-offs attached to the Display chassis using 4 off M6 steel
screws.
Refer to the Figure below for Display Panel Wiring.
