Note 2: The maximum rating is defined as above based on the temperature on the panel surface, which
might be different from ambient temperature after assembling the panel into the application.
Moreover, some temperature-related phenomenon as below needed to be noticed:
- Background color, contrast and response time would be different in temperatures other than
25 C
.
- Operating under high temperature will shorten LED lifetime.

The recommended time period is 1 second.
Note 2: In order to avoid showing uncompleted patterns in transient state. It is recommended that
switching the backlight on is delayed for 1 second after the signals have been applied. The

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.
7) Maximum pressure to the surface of the display must be less than 1,96 x 104 Pa. If the area of
adding pressure is less than 1 cm2, the maximum pressure must be less than 1.96N.
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
C. In high temperature, the color will be slightly dark and blue compared to original pattern.
However, these are temperature-related phenomenon of LCD and it will not cause permanent
damages to the display when used within the operating temperature.
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
bigger than 100 mV.

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