CHARACTER MODULE INITIALIZATION
Internal Reset Circuit
The module is automatically initialized when the power is
applied. The following commands are executed during
initialization. The busy flag is kept in the busy state until
initialization is complete. The busy state lasts for 10 ms
after VDD reaches 4.5 volts.
1) Clear Display
2) Function set
DL=1.......8-bit data length for interface
N=0.........Single-line display
F=0.........5x7 dot matrix character font
3) Display ON/OFF Control
D=0........Display OFF
C=0........Cursor OFF
B=0........Blink function OFF
4) Entry Mode Set
I/D=1......Increment Mode
S=0........Display shift OFF
NOTE:
If the following power conditions are not satisfied, the
internal reset circuit does not function properly. In this
case, the initialization should be executed by the series
of instructions from outside the MPU (Software Initialization).

HANDLING LCD’S & LCD MODULES
CLEANING
l Wipe gently with cotton or soft material soaked in petroleum
benzine.
l Do not use acetone, toluene, ethanol or isopropyl alcohol.
l Contact with water for a long period of time may damage the
display.
SAFETY
l The toxicity of liquid crystal fluid is very low, but wash it off
immediately with soap and water if fluid touches the skin or
clothing.
HANDLING
l Do not touch display area with bare hands.
l Do not touch exposed polarizer with hard objects.
l Do not expose the CMOS IC’s to static electricity.
l Avoid exposing the module to excessive shock or pressure.
l Do not allow the storage temperature to exceed the
specified range.

NOTES:
1. It is recommended that the product be designed so
that the EL back light is not left on continuously.
This will greatly extend the lifo of the back light element.
2. Usable lifetime of the back light is reached when
the light output reaches 50% of the original brightness.

POWER SUPPLY SEQUENCING (Graphics Modules Only)
The power supply voltages should be sequenced according to the following timing diagram. This will insure that the
internal electronics have time to begin operation before the negative voltage is applied. The sequence of events
should be as follows: Apply VDD first. When VDD is stable at 5v, apply the input signals and then apply VL/VEE. The
shut down sequence is exactly the opposite. Failure to follow this procedure may result in permanent damage to
the LCD fluid or to the CMOS electronics on the module.

CHARACTER MODULE FONT TABLE (Standard font)
Character modules with built in controllers and Character Generator (CG) ROM & RAM will display 96 ASCII and special characters in a dot matrix format. Then first 16 locations are occupied by the character generator RAM. These
locations can be loaded with the user designed symbols and then displayed along with the characters stored in the CG
ROM.
