## 3.0 Electrical Specification 

## **3.1 Absolute Maximum Ratings** 

|Item|Symbol|Min.|Max.|Unit|Note|
|---|---|---|---|---|---|
|Power Supply Voltage|VDD|‐0.3|4.0|V|‐|
|Operating Temperature|TOP|‐30|+85|°C|1|
|Storage Temperature|TST|‐40|+90|°C|1,2,3|



**Note 1:** 90% RH Max for Ta<50°C, and 60% RH for Ta≥50°C. 

**Note 2:** In case of below 0°C, the response time of liquid crystal (LC) becomes slower and the colour of panel becomes darker than normal one. Level of retardation depends on temperature, because of LC’s characteristics. 

**Note 3:** Only operation is guaranteed at operating temperature. Contrast, response time, another display quality are evaluated at +25°C.

## 8.0 Handling Precautions 

## **8.1 Handling Precautions** 

- 1) Since the display panel is being made of glass, do not apply mechanical impacts such us dropping from a high position. 

- 2) If the display panel is broken by some accident and the internal organic substance leaks out, be careful not to inhale nor lick the organic substance. 

- 3) If the liquid crystal touches your skin or clothes, wash it off immediately using soap and plenty of water 

- 4) If pressure is applied to the display surface or its neighbourhood of the display module, the cell structure may be damaged and be careful not to apply pressure to these sections. 

- 5) The polarizer covering the surface of the display module is soft and easily scratched. Please be careful when handling the display module. 

- 6) When the surface of the polarizer of the display module has soil, clean the surface. It takes advantage of by using following adhesion tape. 

   - a. Scotch Mending Tape No. 810 or an equivalent 

2. Never try to breathe upon the soiled surface nor wipe the surface using cloth containing solvent such as ethyl alcohol, since the surface of the polarizer will become cloudy. 

3. Also, pay attention that the following liquid and solvent may spoil the polarizer: 

   - Water 

   - Ketone 

   - Aromatic Solvents 

- 7) Hold the display module very carefully when placing it into the system housing. Do not apply excessive stress or pressure to display module. And, do not over bend the film with electrode pattern layouts. These stresses will influence the display performance. Also, secure sufficient rigidity for the outer cases. 

- 8) Do not apply stress to the LSI chips and the surrounding molded sections. 

- 9) Do not disassemble nor modify the display module. 

- 10) Do not apply input signals while the logic power is off. 

- 11) Pay sufficient attention to the working environments when handing display modules to prevent occurrence of element breakage accidents by static electricity. 

   - Be sure to make human body grounding when handling display modules. 

   - Be sure to ground tools to use or assembly such as soldering irons. 

   - To suppress generation of static electricity, avoid carrying out assembly work under dry environments.

   - Protective film is being applied to the surface of the display panel of the display module. Be careful since static electricity may be generated when exfoliating the protective film. 

- 12) Protection film is being applied to the surface of the display panel and removes the protection film before assembling it. If the display module has been stored for a long period of time, residue adhesive material of the protection film may remain on the surface of the display panel after removed of the film. In such case, remove the residue material by the method introduced in the above Section 5). 

- 13) If electric current is applied when the display module is being dewed or when it is placed under high humidity environments, the electrodes may be corroded and be careful to avoid the above. 

## **8.2 Storage Precautions** 

- 1) When storing display modules, put them in static electricity preventive bags avoiding exposure to direct sun light nor to lights of fluorescent lamps, etc. and, also, avoiding high temperature and high humidity environments or low temperature (less than 0°C) environments. (We recommend you to store these modules in the packaged state when they were shipped from Densitron) At that time, be careful not to let water drops adhere to the packages or bags nor let dewing occur with them. 

- 2) If electric current is applied when water drops are adhering to the surface of the display module, when the display module is being dewed or when it is placed under high humidity environments, the electrodes may be corroded and be careful about the above. 

## **8.3 Designing Precautions** 

- 1) The absolute maximum ratings are the ratings which cannot be exceeded for display module, and if these values are exceeded, panel damage may be happen. 

- 2) To prevent occurrence of malfunctioning by noise, pay attention to satisfy the VIL and VIH specifications and, at the same time, to make the signal line cable as short as possible. 

- 3) We recommend you to install excess current preventive unit (fuses, etc.) to the power circuit (VDD). (Recommend value: 0.5A) 

- 4) Pay sufficient attention to avoid occurrence of mutual noise interference with the neighbouring devices. 

- 5) As for EMI, take necessary measures on the equipment side basically. 

- 6) When fastening the display module, fasten the external plastic housing section. 

- 7) If power supply to the display module is forcibly shut down by such errors as taking out the main battery while the display panel is in operation, we cannot guarantee the quality of this display module.

## **8.4 Operation Precautions** 

- 1) It is indispensable to drive the display within the specified voltage limit since excessive voltage shortens its life. 

- 2) Direct current causes an electrochemical reaction with remarkable deterioration of the display quality. Consider prevent direct current during ON/OFF timing and during operation. 

- 3) Response time is extremely delayed at temperatures lower than the operating temperature range while, at high temperatures, displays become dark. However, this phenomenon is reversible and does not mean a malfunction or a display that has been permanently damaged. 

- 4) To protect display modules from performance drops by static electricity rapture, etc., do not touch the following sections whenever possible while handling the display modules. 

   - Pins and electrodes 

   - Pattern layouts such as the FPC 

- 5) When the driver is being exposed (COG), semiconductor elements change their characteristics when light is radiated according to the principle of the solar battery. Consequently, if the driver is exposed to light, malfunctioning may occur. 

   - Design the product and installation method so that the driver may be shielded from light in actual usage. 

   - Design the product and installation method so that the driver may be shielded from light during the inspection processes. 

- 6) Although the display module stores the operation state data by the commands and the indication data, when excessive external noise, etc. enters the module, the internal status may be changed. It therefore is necessary to take appropriate measures to suppress noise generation or to protect from influences of noise on the system design. 

- 7) We recommend you construct its software to make periodical refreshment of the operation statuses (re‐setting of the commands and re‐transference of the display data) to cope with catastrophic noise. 

## **8.5 Other Precautions** 

1) 

Request the qualified companies to handle industrial wastes when disposing of the display modules. Or, when burning them, be sure to observe the environmental and hygienic laws and regulations.
