Note 1: It shall be applied to pixel data signal and clock signal.
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.
Note 3: Fig. 4.1 shows the maximum rating of LED forward current against temperature. The backlight
unit in this display has been set to 80 mA per LED. This is within the range when operating the
display between -20~70 C
.
For the dimming function, reducing the LED backlight voltage 12V to the expected brightness is
recommended. Alternatively, using PWM signal with 10KHz and 3.3V amplitude to dim by
adjusting the duty ratio.

13. PRECAUTIONS
13.1 PRECAUTIONS of MOUNTING
1) Please refer to Fig. 13.1 for housing the display with touch panel into applications. The Fig. 13.1
shows some points as below:
- The cushion needs to be designed between housing and touch panel in order to avoid unexpected
pressure to cause any wrong reactions, and the cushion should be located in the insulated area.
- The housing should not cover the active area of touch panel as the figure shown.
Fig 13.1
13.2 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.
13.3 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 horizont al 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 4
10 x 1,96 Pa. If the area of
adding pressure is less than 1 2
cm , the maximum pressure must be less than 1.96N.
13.4 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.
13.5 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
C~35
Cand 55%~75% humidity to
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 Hitachi, and do not
unpack it.
4) Please do not stick any labels on the display surface for a long time, especially on the polarizer.
