Note 1: All the above voltages are on the basis of “GND = 0V”.

Note 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 3.

“Electrical Characteristics”. If this module is used beyond these conditions,

malfunctioning of the module can occur and the reliability of the module may

deteriorate.

4. Functional Specification

4.1. Commands

Refer to the Technical Manual for the SEPS225

4.2 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.

4.2.1 Power up Sequence:

4. Power down VDD

4.3 Reset Circuit

When RESETB input is low, the chip is initialized with the following status:

1. Frame frequency: 90Hz

2. OSC: internal OSC

3. Internal OSC: ON

4. DDRAM write horizontal address: MX1 = 00h, MX2 = 7Fh

5. DDRAM write vertical address: MY1 = 00h, MY2 = 7Fh

6. Display data RAM write: HC = 1, VC = 1, HV = 0

7. RGB data swap: OFF

8. Row scan shift direction: G0, G1, … , G126, G127

9. Column data shift direction: S0, S1, … , S382, S383

10. Display ON/OFF: OFF

11. Panel display size: FX1 = 00h, FX2 = 7Fh, FY1 = 00h, FY2 = 7Fh

12. Display data RAM read column/row address: FAC = 00h, FAR = 00h

13. Precharge time(R/G/B): 0 clock

14. Precharge current(R/G/B): 0 uA

8. Precautions When Using These OEL Display Modules

8.1 Handling Precautions

1) Since the display panel is being made of glass, do not apply mechanical impacts

such us 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 area, both of top and back sides, or its

neighborhood of the OEL display module, the cell structure may be damaged

and be careful not to touch these sections on carrying and assembly.

4) The polarizer covering the surface of the OEL display module is soft and easily

scratched. Please be careful when handling the OEL display module.

5) When the surface of the polarizer of the OEL display module has soil, clean the

surface. It takes advantage of 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) When installing the OEL display module, be careful not to apply twisting stress

or deflection stress to the OEL 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.

7) Do not apply stress to the LSI chips and the surrounding molded sections.

8) Do not disassemble nor modify the OEL display module.

9) Do not apply input signals while the logic power is off.

10) Pay sufficient attention to the working environments when handing OEL

display modules to prevent occurrence of element breakage accidents by static

electricity.

* Be sure to make human body grounding when handling OEL 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 OEL

display module. Be careful since static electricity may be generated when

exfoliating the protective film.

11) 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 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).

12) If electric current is applied when the OEL display module is being dewed or

when it is placed under high humidity environments, the electrodes may be

corroded and be careful to avoid the above.

8.2 Storage Precautions

1) When storing OEL display modules, put them in static electricity preventive

bags avoiding exposure to direct sun light nor to lights of fluorescent lamps, etc.

and, also, avoiding high temperature and high humidity environments or low

temperature (less than 0°C) environments. (We recommend you to store these

modules in the packaged state when they were shipped from Univision

Technology Inc.)

At that time, be careful not to let water drops adhere to the packages or bags nor

let dewing occur with them.

2) If electric current is applied when water drops are adhering to the surface of the

OEL display module, when the OEL display module is being dewed or when it

is placed under high humidity environments, the electrodes may be corroded

and be careful about the above.

8.3 Designing Precautions

1) The absolute maximum ratings are the ratings which cannot be exceeded for

OEL display module, and if these values are exceeded, panel damage may be

happen.

2) To prevent occurrence of malfunctioning by noise, pay attention to satisfy the

VIL and VIH specifications and, at the same time, 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). (Recommend value: 0.5A)

4) Pay sufficient attention to avoid occurrence of mutual noise interference with

the neighboring devices.

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

6) When fastening the OEL display module, fasten the external plastic housing

section.

7) If power supply to the OEL display module is forcibly shut down by such errors

as taking out the main battery while the OEL display panel is in operation, we

cannot guarantee the quality of this OEL display module.

8) The electric potential to be connected to the rear face of the IC chip should be

as follows: SSPS225

* Connection (contact) to any other potential than the above may lead to

rupture of the IC.

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) 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

23

Doc. No: SAS1-XXXX-A

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 COF

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 indication data, when excessive external noise, etc. enters

into the module, the internal status may be changed. It therefore is necessary

to take appropriate measures to suppress noise generation or to protect from

influences of noise on the system design.

5) We recommend you to construct its software 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.
