Static Electricity Be sure that you are grounded when handling displays.

Note 1: All the above voltage are on the basis of “GND=0V”. Note 2: When this module is used beyond the above absolute maximum ratings, permanent

breakage of the module may occur. Also, for normal operations, it’s desirable to use this module under the conditions according to Section 3 “Electrical Characteristics”. If this module is used beyond these conditions, malfunctioning of the module can occur and the reliability of the module may deteriorate.

3.1.1 Regarding the Gradation Although this module possesses the gradation function, respective gradation levels will

vary depending on the production conditions etc. Also, the temperature range where the grading function can be guaranteed will be -10~60°C.

Power Supply for OLE system.

This is the most positive voltage supply pin of the chip. It must be connected to external source.

Ground for OLED panel.

This is a ground pin. It also acts as a reference for the logic pins, the OLED driving voltages and the analog circuits. It must be connected to external ground.

Power Supply for Core Logic operation

This is a voltage supply pin. It must be connected to external source.

Power Supply for Interface Logic level.

This is a voltage supply pin. It should be match with MCU interface voltage level. VDDIO must allways be equal or lower than VDD

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 V 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).
