## **1. Application recommendations** 

Recommended components ： C1, C2, C3 ： 4.7uF 

Bus Interface selection: (Must be set the IM[2:1], refer to item 3) 8-bits 6800 or 8080 parallel, 4-wire SPI, I2C 

Voltage at IREF = VPP – 3.5V. For VPP = 13V, IREF = 18.75uA: (R1 + 150K) = (Voltage at IREF - VSS) / IREF R1 = [(13 - 3.5) V / 18.75uA] - 150K ohm ≧ 357K ohm[(2)] 

R1 recommends 562K ohm. If new module want to be compatible with hardware using past module (IC SSD1309 with higher R1), then the initial code must be modified to meet typical brightness (adjust contrast or VCOM to higher level). 

## Note: 

(1).The capacitor value is recommended value. Select appropriate value against module application. (2).Minimum value. When OLED product application, then R1 must be greater than the calculated value.

## **Absolute Maximum Ratings** 

|**Parameter**|**Symbol**|**Min**|**Max**|**Unit**|**Notes**|
|---|---|---|---|---|---|
|Supply Voltage for Logic|VDD1|-0.3|3.6|V|1, 2|
|Supply Voltage for Display|VPP|0|14.5|V|1, 2|
|Operating Temperature|TOP|-40|+80|°C|-|
|Storage Temperature|TSTG|-40|+85|°C|-|



## Note ： 

1. All the above voltages are on the basis of “VSS = 0V”. 

2. When this module is used beyond the above absolute maximum ratings, permanent breakage of the module may occur. Also, for normal operations, it is desirable to use this module under the conditions according to Section 6 ‘’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. The absolute limit temperature was verified according to the test conditions of reliability test (See section 9. Reliability) , and module was met all criteria. 

4. The defined temperature ranges do not include the polarizer. The maximum withstood temperature of the polarizer should be 80 °C.

Note: The VCC (VPP) value can be adjusted according to the demand brightness. When VCC (VPP) is lowered, the brightness decreases or when VCC (VPP) is increased, the brightness increases. The VCC (VPP) value is set within the recommended range. The life time of OLED is directly related to the set brightness, and lower brightness helps to improve the life time.

WriteCommand(0xAE); //display off WriteCommand(0xB0); //set page address WriteCommand(0x10); //set higher column address WriteCommand(0x04); //set lower column address WriteCommand(0xD5); // set display clock divide ratio/oscillator frequency WriteCommand(0xF0); WriteCommand(0xA8); //Multiplex Ration WriteCommand(0x3F); WriteCommand(0xD3); //set display offset WriteCommand(0x00); WriteCommand(0x40); //set start line WriteCommand(0xAD); //DC-DC Control Mode Set WriteCommand(0x8A); //DC-DC OFF WriteCommand(0xA1); //set segment re-map WriteCommand(0xC8); //set common output scan direction WriteCommand(0xDA); //common pad configuration WriteCommand(0x12); WriteCommand(0x81); //set contrast WriteCommand(0x1F); WriteCommand(0xD9); //set dis-charge/pre-charge period WriteCommand(0x1f); WriteCommand(0xDB); //set VCOM deselect level WriteCommand(0x30); WriteCommand(0xA4); //set entire display off WriteCommand(0xA6); //set normal display WriteCommand(0xAF); //display on 

## } 

Note 1: Initial code is for reference only. Please make the best adjustment with the OLED module. Note 2: Command: Set Contrast Control (0x81) , This command sets the Contrast Setting of the display. The chip has 256 contrast steps from 00h to FFh. The segment output current increases as the contrast step value increases. The segment current increases, the OLED brightness increases.

## **I2C-bus data format** 

## **Note1:** 

1. Co ＝“ 0 ” : The last control byte , only data bytes to follow, 

   - Co ＝“ 1 ” : Next two bytes are a data byte and another control byte; 

2. D / C ＝“ 0 ” : The data byte is for command operation, 

   - D / C ＝“ 1 ” : The data byte is for RAM operation. 

3. SA0 ＝ Slave address bit 

## **I2C address bit (SA0)** 

The slave address is following the start condition for recognition use. The slave address is either “b0111100” or “b0111101” by changing the SA0 to LOW or HIGH (A0 pin acts as SA0).

## **Precautions in use of OLED Modules** 

## Modules 

- (1) Avoid applying excessive shocks to module or making any alterations or modifications to it. 

- (2) Don’t make extra holes on the printed circuit board, change the components or modify its shape of OLED display module. 

- (3) Don’t disassemble the OLED display module. 

- (4) Do not apply input signals while the logic power is off. 

- (5) Don’t operate it above the absolute maximum rating. 

- (6) Don’t drop, bend or twist OLED display module. 

- (7) Soldering: only to the I/O terminals. 

- (8) Hot-Bar FPC soldering condition: 280~350C, less than 5 seconds. 

- (9) Midas Displays has the right to change the passive components (Resistors, capacitors and other passive components will have different appearance and color caused by the different supplier.) and change the PCB Rev. (In order to satisfy the supplying stability, management optimization and the best product performance...etc, under the premise of not affecting the electrical characteristics and external dimensions, Midas Displays have the right to modify the version.) 

- (10) Midas Displays has the right to upgrade or modify the product function. 

- (11) For COG & COF structure OLED products, customers should reserve VCC (VPP) adjustment function or software update function when designing OLED supporting circuit. (The progress of OLED light-emitting materials will increase the conversion efficiency and the brightness. The brightness can be adjusted if necessary).. 

## **1. Handling Precautions** 

- (1) Since the display panel is being made of glass, do not apply mechanical impacts such as dropping from a high position. 

- (2) 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. 

- (3) If pressure is applied to the display surface or its neighborhood of the OLED display module, the cell structure may be damaged. So, be careful not to apply pressure to these sections. 

- (4) The polarizer covering the surface of the OLED display module is soft and easily scratched. 

- (5) When the surface of the polarizer of the OLED display module has soil, clean the surface. It takes advantage by using following adhesion tape. 

   - Scotch Mending Tape No. 810 or an equivalent 

   - Never try to breathe upon the soiled surface nor wipe the surface using cloth containing solvent such as ethyl alcohol, since the surface of the polarizer will become cloudy. Also, pay attention that the following liquid and solvent may spoil the polarizer: 

   - Water 

   - Ketone 

   - Aromatic Solvents 

- (6) Protection film is being applied to the surface of the display panel and removes the protection film before assembling it. At this time, if the OLED 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. 

- (7) Do not touch the following sections whenever possible while handling the OLED display modules. 

   - Pins and electrodes 

   - Pattern layouts such as the TCP & FPC 

Page 21 of 23 

- (8) Hold OLED display module very carefully when placing OLED display module into the System housing. Do not apply excessive stress or pressure to OLED display module. And, do not over bend the film with electrode pattern layouts. These stresses will influence the display performance. Also, secure sufficient rigidity for the outer cases. 

- (9) Do not apply stress to the LSI chips and the surrounding molded sections. 

- (10) Pay sufficient attention to the working environments when handing OLED display modules to prevent occurrence of element breakage accidents by static electricity. 

   - Be sure to make human body grounding when handling OLED display modules. 

   - Be sure to ground tools to use or assembly such as soldering irons. 

   - To suppress generation of static electricity, avoid carrying out assembly work under dry environments. 

   - Protective film is being applied to the surface of the display panel of the OLED display module. Be careful since static electricity may be generated when exfoliating the protective film. 

## **2. Storage Precautions** 

- (1) When storing OLED display modules, put them in static electricity preventive bags to avoid be directly exposed to sun or lights of fluorescent lamps. And, also, place in the temperature 25±5°C and Humidity below 65% RH.(We recommend you to store these modules in the packaged state when they were shipped from Midas Displays. At that time, be careful not to let water drops adhere to the packages or bags.) 

- (2) When the OLED display module is being dewed or when it is placed under high temperature or high humidity environments, the electrodes may be corroded if electric current is applied. Please store it in clean environment. 

## **3. Designing Precautions** 

- (1) The absolute maximum ratings are the ratings which cannot be exceeded for OLED display module, and if these values are exceeded, OLED display module may be damaged. 

- (2) To prevent occurrence of malfunctioning by noise, pay attention to satisfy the VIL and VIH specification and to make the signal line cable as short as possible. 

- (3) We recommend you to install excess current preventive unit (fuses, etc.) to the power circuit (VDD / VCC). (Recommend value: 0.5A) 

- (4) Pay sufficient attention to avoid occurrence of mutual noise interference with the nearby devices. 

- (5) As for EMI, take necessary measures on the equipment side basically. 

- (6) If the power supplied to the OLED display module is forcibly shut down by such errors as taking out the main battery while the OLED display panel is in operation, we cannot guarantee the quality of this OLED display module. 

   - Connection (contact) to any other potential than the above may lead to rupture of the IC. 

- (7) If this OLED driver is exposed to light, malfunctioning may occur and semiconductor 

Page 22 of 23 

elements may change their characteristics. 

- (8) The internal status may be changed, if excessive external noise enters into the module. Therefore, it is necessary to take appropriate measures to suppress noise generation or to protect module from influences of noise on the system design. 

- (9) We recommend you to make periodical refreshment of the operation statuses (re-setting of the commands and re-transference of the display data) to cope with catastrophic noise. 

- (10) It's pretty common to use "Screen Saver" to extend the lifetime and Don't use the same image for long time in real application. When an OLED display module is operated for a long of time with fixed pattern, an afterimage or slight contrast deviation may occur. 

- (11) The limitation of FPC and Film bending. 

- (12) The module should be fixed balanced into the housing, or the module may be twisted.

- (13) Please heat up a little the tape sticking on the components when removing it; otherwise the components might be damaged. 

## **4. Precautions when disposing of the OLED display modules** 

- (1) Request the qualified companies to handle industrial wastes when disposing of the OLED display modules. Or, when burning them, be sure to observe the environmental and hygienic laws and regulations.
