## Notes 

## Repeated procedures for an 4-bit bus interface 

Noise causing transfer mismatch between the four upper and lower bits can be corrected by a reset triggered by consecutively writing a “0000” instruction five times. The next transfer starts from the lower four bits and then first instruction “Function set” can be executed normally. Please insert the synchronization function in the head of procedures. The repeated procedures are show as follows : 

Note: Initial code is for reference only. Please make the best adjustment with the OLED module.

## **Test and measurement conditions** 

1. All measurements shall not be started until the specimens attain to temperature stability. After the completion of the described reliability test, the samples were left at room temperature for 2 hrs prior to conducting the failure test at 23±5°C; 55±15% RH. 

2. All-pixels on/off exchange is used as operation test pattern. 

3. The degradation of Polarizer are ignored for High Temperature storage, High Temperature/ Humidity Storage, Temperature Cycle 

## **Evaluation criteria** 

1. The function test is OK. 

2. No observable defects. 

3. Luminance: > 50% of initial value. 

4. Current consumption: within ± 50% of initial value. 

## **APPENDIX:** 

## **RESIDUE IMAGE** 

Because the pixels are lighted in different time, the luminance of active pixels may reduce or differ from inactive pixels. Therefore, the residue image will occur. To avoid the residue image, every pixel needs to be lighted up uniformly.

## **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 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 have the right to modify the version.) 

- (10) Midas = 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 19 of 21 

- (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. 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

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.
