悠景科技股份有限公司 3. Symbol define D0-D7：These pins are bi-directional data bus connecting to the MCU data bus. For SPI application, D[0]=SCLK & D[1]=SDIN. Unused pins are recommended to tie LOW except D[2]. BS0,BS1,BS2,BS3：MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS3 and BS2 are command programmable (by command ABh).[reset = 00]. BS1 and BS0 are pin select (J3, J4). Regarding to the application of BS3 and BS2, they should be fixed as 00.
悠景科技股份有限公司 When the pin is pulled LOW, the data at D[7:0] will be interpreted as command. 4-Wire SPI Interface D/C pin Data/Command control pin connecting to the MCU. 3-Wire SPI Interface D/C pin Tie Low. RES#：This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation. CS#：This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW.

悠景科技股份有限公司 Figure 6 The combination of the module and EVK Because the package of UG-2828GDEDF11 is COF, that the connect pads are on the top of the module, and the connector which on the EVK PCB board is double size connect type. So when assemble the module with EVK. The module must face up first and plug into the connector. When finished assembled the module and EVK, then push the locking pad to lock the module. See the figure 6. When finished assembled the module and EVK.
悠景科技股份有限公司 6. Power down and Power up Sequence To protect OLED 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. Such that panel has enough time to charge up or discharge before/after operation. Power up Sequence: 1. Power up VCI & VDDIO 2. Send Display off command 3. Driver IC Initial Setting 4. Clear Screen 5. Power up VCC 6. Delay 100ms (when VCC is stable) 7.

Precautions When Using These OEL Display Modules 8.1 Handling Precautions 1) 2) 3) 4) 5) 6) Since the display panel is being made of glass, do not apply mechanical impacts such us dropping from a high position. 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.
Univision Technology Inc. Doc. No: SAS1-D038-A the protection film before assembling it. At this time, if the OEL 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).
Univision Technology Inc. Doc. No: SAS1-D038-A 8.4 Precautions when disposing of the OEL display modules 1) Request the qualified companies to handle industrial wastes when disposing of the OEL display modules. Or, when burning them, be sure to observe the environmental and hygienic laws and regulations. 8.5 Other Precautions 1) 2) 3) 4) 5) 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.
