We recommend allowing field adjustment of V0 for all designs. The optimal value for V0 will change with
temperature, variations in VDD, and viewing angle. V0 will also vary module-to-module and batch-to-batch due
to normal manufacturing variations.
Ideally, adjustment to V0 should be available to the end user so each user can adjust the display to the optimal
contrast for their required viewing conditions. As a minimum, your design should allow V0 to be adjusted as part
of your product’s final test.
Although a potentiometer is shown as a typical connection, V0 can be driven by your microcontroller, either by
using a DAC or a filtered PWM. Displays that require V0 to be negative may need a level-shifting circuit. Please
do not hesitate to contact Tinsharp application support for design assistance on your application.
(2) MPU Interface 4-bit/8-Bit
There are tow types of data operations: 4-bit and 8-bit operations. Using 4-bit MPU, the interfacing 4-bit data is
transferred by 4-busline (DB4~DB7). Thus, DB0 to DB3 bus lines are not used. Using 4-bit MPU to interface
8-bit data requires tow times transferring. First, the higher 4-bit data is transferred by 4-busline (for 8-bit
operation, DB7~DB4). Secondly, the lower 4-bit data is transferred by 4-busline (for 8-bit operation, DB3~
DB0). For 8-bit MPU, the 8-bit data is transferred by 8-busline (DB0~DB7).

DISPLAY DATA RAM (DD RAM)
The 80-bit DD RAM is normally used for storing display data. Those DD RAM not used for display data can be
used as general data RAM. Its address is configured in the Address Counter.
Timing Generation Circuit
The timing generating circuit is able to generate timing signals to the internal circuits. In order to prevent the
internal timing interface, the MPU access timing and the RAM access timing are generated independently.
LCD Driver Circuit
Total of 16 commons and 40 segments signal drivers are valid in the LCD driver circuit. When a program specifies
the character fonts and line numbers, the corresponding common signals output drive-waveforms and the others
still output unselected waveforms. The relationships between Display Data RAM Address and LCD′s position
are depicted as follows.
Character Generator ROM (CG ROM)
Using 8-bit character code, the character generator ROM generates 5 x 8 dots or 5 x 10 dots character patterns.
It also can generate 192’s 5 x 8 dots character patterns and 64’s 5 x 10 dots character patterns.
Character Generator RAM (CG RAM)
Users can easily change the character patterns in the character generator RAM through program. It can be
written to 5 x 8 dots, 8-character patterns or 5 x 10 dots for 4-character patterns.

PRECAUTION FOR USING LCM MODULE
„
Please remove the protection foil of polarizer before using.
„
The display panel is made of glass. Do not subject it to a mechanical shock by dropping it from a high place, etc.
„
If the display panel is damaged and the liquid crystal substance inside it leaks out, do not get any in your mouth. If the
substance come into contact with your skin or clothes promptly wash it off using soap and water.
„
Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary.
„
The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarize
carefully.
„
To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment.
-Be sure to ground the body when handling the LCD module.
-Tools required for assembly, such as soldering irons, must be properly grounded.
-To reduce the amount of static electricity generated, do not conduct assembly and other work under dry conditions.
-The LCD module is coated with a film to protect the display surface. Exercise care when peeling off this protective
film since static electricity may be generated.
Storage precautions
When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps.
Keep the modules in bags designed to prevent static electricity charging under low temperature / normal humidity
conditions (avoid high temperature / high humidity and low temperatures below 0℃).Whenever possible, the LCD
modules should be stored in the same conditions in which they were shipped from our company.
„
OTHERS
„
Liquid crystals solidify at low temperature (below the storage temperature range) leading to defective orientation of
liquid crystal or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is
subjected to a strong shock at a low temperature.
„
If the LCD modules have been operating for a long time showing the same display patterns may remain on the screen
as ghost images and a slight contrast irregularity may also appear. Abnormal operating status can be resumed to be
normal condition by suspending use for some time. It should be noted that this phenomena does not adversely affect
performance reliability.
„
To minimize the performance degradation of the LCD modules resulting from caused by static electricity, etc. exercise
care to avoid holding the following sections when handling the modules :
- Exposed area of the printed circuit board
- Terminal electrode sections
