1 Commands Refer to the Technical Manual for the SSD1306

2 Power down and Power up Sequence To protect OEL panel and extend the panel life time, 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 OEL panel enough time to complete the action of charge and discharge before/after the operation.

2.1 Power up Sequence:

1. Power up VDD 2. Send Display off command 3. Initialization 4. Clear Screen 5. Power up VCC/ VBAT 6. Delay 100ms (When VCC is stable) 7. Send Display on command

2.2 Power down Sequence:

1. Send Display off command 2. Power down VCC / VBAT 3. Delay 100ms (When VCC / VBAT is reach 0 and panel is completely discharges) 4. Power down VDD Note

Note 13:

1) Since an ESD protection circuit is connected between VDD and VCC inside the driver IC, VCC becomes lower than VDD whenever VDD is ON and VCC is OFF.

2) VCC / VBAT should be kept float (disable) when it is OFF.

3) Power Pins (VDD, VCC, VBAT) can never be pulled to ground under any circumstance.

4) VDD should not be power down before VCC / VBAT power down.

3. Reset Circuit When RES# input is low, the chip is initialized with the following status:

1. Display is OFF

2. 128x64 Display Mode

3. Normal segment and display data column and row address mapping (SEG0 mapped to column address 00h and COM0 mapped to row address 00h)

4. Shift register data clear in serial interface

5. Display start line is set at display RAM address 0

6. Column address counter is set at 0

7. Normal scan direction of the COM outputs

8. Contrast control register is set at 7Fh

9. Normal display mode (Equivalent to A4h command)

Other Precautions

1) When an OEL 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.

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

* Pins and electrodes

* Pattern layouts such as the FPC

3) With this OEL display module, the OEL driver is being exposed. Generally speaking, semiconductor elements change their characteristics when light is radiated according to the principle of the solar battery. Consequently, if this OEL driver is exposed to light, malfunctioning may occur.

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

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

4) Although this OEL display module stores the operation state data by the commands and the
