Note 1: The rating is defined for the signal voltages of the interface such as CLK, DE, Hsync, Vsync,
and RGB data bus.
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.

(3) TIMING BETWEEN INTERFACE SIGNAL AND POWER SUPPLY
Power Supply, Input Signal and Backlight Voltage ON/OFF/REENTRY should comply with the following
sequence.
Note 1: In order to prevent electronic parts from destruction caused by latch-up, please input signal
after Power Supply Voltage ON. In addition, please turn off signals before power supply
voltage OFF.
Note 2: In order to prevent from function error due to residual charge, please reenter power supply
voltage after time stipulated with t7.
Note 3: Please turn on Backlight after signals fix and turn off before signals down, otherwise noise
appears in the display. The noise cause no problem with display performance in case of timing
sequence comply with the spec.

13. PRECAUTIONS
13.1 PRECAUTIONS of TOUCH PANEL
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 cushion area.
- The housing should not cover the active area of touch panel as the figure shown.

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 using sharp tools harder than 3H, especially touch panel, metal frame and polarizer.
2) Please do not stack the displays as this may damage the surface. In order to avoid any injuries,
please avoid touching the edge of the glass or metal frame and wore gloves during handling.
3) Touching the polarizer or terminal pins with bare hand should be avoided to prevent staining and
poor electrical contact.
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 permanent damages.
7) Maximum pressure to the surface of the display must be less than 4
10 x 1,96 Pa. If the area of
applied pressure is less than 1 2
cm , the maximum pressure must be less than 1.96N.

13.4 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
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.

14. DESIGNATION of LOT MARK
1) The lot mark is showing in Fig.13.1. First 4 digits are used to represent production lot, T represented
made in Taiwan, and the last 6 digits are the serial number.
2) The tables as below are showing what the first 4 digits of lot mark are shorted for.
3) Except letters I and O, revision number will be showen on lot mark and following letters A to Z.
4) The location of the lot mark is on the back of the display shown in Fig. 14.1.
