11. OPERATING PRINCIPLES & METHODS

11-1. I/O Buffer

Input buffer controls the status between the enable the and disable of chip. Unless the CS1 to CS2 is in active mode. Input or output of data and instruction does not execute. Therefore internal stade is not change. Bust RSTB and ADC can operate regardless CS1-CS2.

11-2. Input register

Input register is provided to interface with MPU which is different operating frequency. Input register stores the data temporarily before writing it into display RAM. When CS1 to CS2 are in the active mode, R/W and RS select the input register. The data from MPU is written into input register. Then Writing it into display RAM. Data latched for the E signal and write automatically into the display data RAM by internal operation.

11-3. Output register

Output register stores the data temporarily from display data RAM when CS1 and CS2 are in active mode and R/W and RS=H, stored data in display data RAM is latched in output register. When CS1 to CS2 are in the active mode and R/W=H, RS=L, status data (busy check) can read out. To read the contents of display data RAM, twice access of read instruction needed. In first access, data in display data RAM is latched into output register. In second access, MPU can read data which is latched. That is , to read the data in display data RAM, it needs dummy read. But staus read is not read needed dummy.

11-4. Reset

The system can be initialized by setting RSTB terminal at low level when turning power on receiving instruction from RAM. When RSTB becomes low, following procedure is occurred.

1. Display off

2. Display start line register become set by 0. (Z-address 0) While RSTB is low, No instruction except status read can be accepted. Therefore, execute other instructions after making sure than DB4=0 (clear RSTB) and DB7=0 (ready) by status read instruction.

11 -6. Display ON/OFF Flip-Flop

The display on/off flip-flop makes on/off the liquid crystal display. When flip-flop is reset (logical low). selective voltage or non selective voltage appears on segment output terminals. When flip-flop is set (logic high), non selective voltage appears on segment output terminals regardless of display RAM data. The display on/off flip-flop can changes status by instruction. The display data at all segment disappear while RSTB is low. The status of the flip-flop is output to DB5 by status read instruction.

11-7. X Page Register

X page register designates pages of the internal display data RAM. Count function is not available. An adders is set by instruction.

11-8. Y address counter

Y address counter designates address of the internal data RAM. An address is set by instruction and is increased by 1

automatically by read or write operations of display data.

11-9. Display Data RAM

Display Data RAM stores a display data for liquid crystal display. To indicate on state dot matrix of liquid crystal display, write data 1. The other way , off state, writes 0.

11-10. Display Start Line Register

The display start line register indicates of display data RAM to display top liquid crystal display. Bit data (DB<0:5>) of the display start line set instruction is latched in display start line register. Latched data is transferred to the Z address counter while FRM is high, presetting the Z address counter. It is used for scrolling of the liquid crystal display screen.

12. DISPLAY CONTROL INSTRUCTION

The display control instructions the internal state of the SBN0064G. Instruction is received from MPU to SBN0064G for the display control. The following table shows various instructions.

13. LCD MODULES HANDLING PRECAUTIONS

 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 comes 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

polarizercarefully.

 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°C). Whenever possible, the LCD modules should be stored in the same conditions in which they were shipped from our company.

14. 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 sectio ns
