The DLO4135/DLG4137
5 x 7 Dot Matrix Intelligent Display
®
Appnote 28
This application note is intended to serve as a design and appli-
cation guide for users of the DLO4135 and DLG4137 OSRAM
Intelligent Displays. This appnote covers device electrical
description, operation, general circuit design considerations,
and interfacing to microprocessors.
Electrical Description
The DLO4135/DLG4137 Intelligent Alphanumeric 5x7 Dot
Matrix Display contains memory, character generator, multi-
plexing circuits, and drivers built into a single package.
Figure 1 is a block diagram of DLO4135/DLG4137. 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.

for industrial control applications. Display construction is filled
reflector type with the integrated 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.
