## **5 FUNCTIONAL SPECIFICATION**
## _**5.1 COMMANDS**_
Please refer to the Technical Manual for the SSD1305
## _**5.2 POWER UP/DOWN SEQUENCE**_
To protect panel and extend the panel lifetime, the driver IC power up/down routine should include a delay period between high voltage and low voltage power sources during turn on/off. It gives the panel enough time to complete the action of charge and discharge before/after the operation.

## _**7.3 DEALING WITH CUSTOMER COMPLAINTS**_
## **7.3.1 Non-conforming analysis**
Purchaser should supply Densitron with detailed data of non-conforming sample. After accepting it, Densitron should complete the analysis in two weeks from receiving the sample.
If the analysis cannot be completed on time, Densitron must inform the purchaser.
## **7.3.2 Handling of non-conforming displays**
If any non-conforming displays are found during customer acceptance inspection which Densitron is clearly responsible for, return them to Densitron.
Both Densitron and customer should analyse the reason and discuss the handling of nonconforming displays when the reason is not clear.
Equally, both sides should discuss and come to agreement for issues pertaining to modification of Densitron quality assurance standard.

## **9 HANDLING PRECAUTIONS**
## _Safety_
If the panel breaks, be careful not to get the organic substance in your mouth or in your eyes. If the organic substance touches your skin or clothes, wash it off immediately using soap and plenty of water.
## _Mounting and Design_
Place a transparent plate (e.g. acrylic, polycarbonate or glass) on the display surface to protect the display from external pressure. Leave a small gap between the transparent plate and the display surface.
Design the system so that no input signal is given unless the power supply voltage is applied.
## _Caution during OLED cleaning_
Lightly wipe the display surface with a soft cloth soaked with Isopropyl alcohol, Ethyl alcohol or Trichlorotriflorothane.
Do not wipe the display surface with dry or hard materials that will damage the polariser surface. Do not use aromatic solvents (toluene and xylene), or ketonic solvents (ketone and acetone).
## _Caution against static charge_
As the display uses C-MOS LSI drivers, connect any unused input terminal to VDD or VSS. Do not input any signals before power is turned on.
Also, ground your body, work/assembly table and assembly equipment to protect against static electricity.
## _Packaging_
Displays use OLED elements, and must be treated as such. Avoid strong shock and drop from a height.
To prevent displays from degradation, do not operate or store them exposed directly to sunshine or high temperature/humidity.
## _Caution during operation_
It is indispensable to drive the display within the specified voltage limit since excessive voltage shortens its life.
## _Other Precautions_
When a display module is operated for a long of time with fixed pattern may remain as an after image or slight contrast deviation may occur.
Nonetheless, if the operation is interrupted and left unused for a while, normal state can be restored. Also, there will be no problem in the reliability of the module.
## _Storage_
Store the display in a dark place where the temperature is 25°C ± 10°C and the humidity below 50%RH.
Store the display in a clean environment, free from dust, organic solvents and corrosive gases. Do not crash, shake or jolt the display (including accessories).
