Power Supply for Panel.

This is the most positive voltage supply pin of the chip. It can be supplied externally or generated internally by using internal DC/DC voltage converter.

Voltage Output High Level for COM Signal.

This pin is the input pin for the voltage output high level for COM signal. A capacitor should be connected between this pin and VSS.

Current Reference for Brightness Adjustment.

This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current at 10uA.

Host Data Input/Output Bus. These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus.

Read/Write Enable or Read.

This pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low.

Read/Write Select or Write.

This pin is the Write (WR#) input. Data write operation is initiated when this pin is pulled low and CS# ispulled low

Data/Command Control.

This pin is Data/Command control pin. When the pin is pulled high, the input at D7~D0 is treated as display data. When the pin is pulled low, the input at D7~D0 will be transferred to the command register. For detail relationship to MCU interface signal, please refer to the Timing Characteristics Diagrams.

Power Reset for Controller and Driver.

This pin is reset signal input. When the pin is low, initialization of the chip executed.

Chip Select.

This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low.

Power Supply for Logic circuit

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

Ground

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

Reserved Pin (Supporting Pin).

The supporting pin can reduce the influences from stresses on the function pins.

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).
