3.2 APPLICATION AND OTHERS

(1) This LCD module was designed and manufactured to be used in an air-conditioned room away from

direct sunlight.

(2) This LCD module cannot be applied to an instrument which requires extremely high reliability and

safety from its functions and precision. These instruments include medical equipment which affects
life- and/or wealth-support apparatus.

(3) Any problems caused by a use with deviation from the conditions mentioned in this specification are

not included in the warranty.

(4) Maintenance

This LCD module and the aforementioned data may be changed without notice. When you demand
maintenance parts, please inquire about the changes in advance.

(5) Repair

We will replace or repair all defective modules if the relevant defect is caused by KOE. However, we
will not take any responsibilities for defective modules after the expiration of warranty period. Also, if
you access the modules for repairs, we will not warrant them either even if it is within the warranty
period.

(6) Items in this specification may be changed for improvement without prior notice. Please consult our

sales division before engineering an instrument with this LCD module.

Notes 1) RSVD (reserved) pins on a transmitter should be connected with Vss.

2) The system must have a LVDS transmitter to drive a module.

Moreover, each channel must have a DTMG signal.

3) The impedance of LVDS cable should be 50 ohms per a signal line or about 100 ohms per

a twist-pair line when it is used differentially.

- The defect area of the dot must be bigger than half of a dot.

- For bright dot-defect, showing black pattern, the dot’s brightness must be over 30% brighter

than others.

- For dark dot-defect, showing white pattern, the dot’s brightness must be under 70% darker

than others.

- The definition of 1-dot-defect is the defect-dot, which is isolated and no adjacent defect-dot.

12. PRECAUTIONS

12.1 PRECAUTIONS of ESD

1) Before handling the display, please ensure your body has been connected to ground to avoid any
damages by ESD. Also, do not touch display’s interface directly when assembling.

2) Please remove the protection film very slowly before turning on the display to avoid generating ESD.

12.2 PRECAUTIONS of HANDLING

1) In order to keep the appearance of display in good condition, please do not rub any surfaces of the
displays by sharp tools harder than 3H, especially touch panel, metal frame and polarizer.

2) Please do not pile the displays in order to avoid any scars leaving on the display. In order to avoid
any injuries, please pay more attention for the edges of glasses and metal frame, and wear finger
cots to protect yourself and the display before working on it.

3) Touching the display area or the terminal pins with bare hand is prohibited. This is because it will
stain the display area and cause poor insulation between terminal pins, and might affect display’s
electrical characteristics furthermore.

4) Do not use any harmful chemicals such as acetone, toluene, and isopropyl alcohol to clean display’s
surfaces.

5) Please use soft cloth or absorbent cotton with ethanol to clean the display by gently wiping.
Moreover, when wiping the display, please wipe it by horizontal or vertical direction instead of
circling to prevent leaving scars on the display’s surface, especially polarizer.

6) Please wipe any unknown liquids immediately such as saliva, water or dew on the display to avoid
color fading or any permanently damages.

12.3 PRECAUTIONS OF OPERATING

1) Please input signals and voltages to the displays according to the values defined in the section of
electrical characteristics to obtain the best performance. Any voltages over than absolute maximum
rating will cause permanent damages to this display. Also, any timing of the signals out of this
specification would cause unexpected performance.

2) When the display is operating at significant low temperature, the response time will be slower than it

at 25
However, these are temperature-related phenomenon of LCD and it will not cause permanent
damages to the display when used within the operating temperature.



C

. In high temperature, the color will be slightly dark and blue compared to original pattern.

3) The use of screen saver or sleep mode is recommended when static images are likely for long
periods of time. This is to avoid the possibility of image sticking.

4) Spike noise can cause malfunction of the circuit. The recommended limitation of spike noise is no

12.4 PRECAUTIONS of STORAGE

If the displays are going to be stored for years, please be aware the following notices.

1) Please store the displays in a dark room to avoid any damages from sunlight and other sources of
UV light.

2) The recommended long term storage temperature is between 10

avoid causing bubbles between polarizer and LCD glasses, and polarizer peeling from LCD glasses.

3) It would be better to keep the displays in the container, which is shipped from KOE, and do not
unpack it.

4) Please do not stick any labels on the display surface for a long time, especially on the polarizer.
