IEE - LRT1704R Opto Display - 5 x 7 Alpha-Numeric Dot Matrix Display.

IEE has over 70 years of experience building custom military and industrial displays. 

The LDP-080705R is a retro red color 8 digit 5x7 (+ decimal) pixel LED matrix display. The module is based on eight LRT1704R display modules (equivalent the TIL307 display) and two TLC5920 from TI which allows all those LEDs to be controlled with only 7 microcontroller I/O lines.  Pixels can show as black (that is, completely unlit), or red.  Uses a standard HUB08 connection, so you can use the PLT-1001 driver boards to control it. Same display units as used in the classic SR-60 Programmable Calculator.
