Intelligent Display^® Device
Appnote 25
This application note is intended to serve as a design and appli-
cation guide for users of the DLO7135 and DLG7137 OSRAM
Intelligent Displays. This appnote covers device electrical
description, operation, general circuit design considerations
and interfacing to microprocessors.
Electrical Description
The DLX713X intelligent alphanumeric 5x7 dot matrix display
contains memory, character generator, multiplexing circuits,
and drivers built into a single package.
Figure 1 is a block diagram of the DLX713X. The unit consists
of 35 LED die arranged in a 5x7 pattern and a single CMOS
integrated circuit chip. The IC chip contains the column drivers,
row drivers, 128 character generator ROM, memory, multiplex
and blanking circuitry.

Package
Thirty-five dots form a 0.48 x 0.68 inch overall character size in
a 0.700 x 0.800 inch dual-in-line package. The ±50 degree wide
viewing angle complements the large display and is the ideal
display for industrial control applications. Display construction is
filled reflector type with the intregrated circuit in the back also
filled with IC-grade epoxy. This results in a very rugged part
which is resistant to moisture, shock, and vibration.
