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 beused 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 theinternal 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 specifiesthe character fonts and line numbers, the corresponding common signals output drive-waveforms and the othersstill output unselected waveforms. The relationships between Display Data RAM Address and LCD ′ s positionare 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 bewritten 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 thesubstance 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 polarizecarefully.

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 LCDmodules 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 ofliquid 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 screenas 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
