ITEM
(Note 1) Please design your lamp driving circuit (inverter) according to the above specifications,
and inf orm Hitachi of it.
(Note 2) Starting discharge voltage is increased w hen LCM is operating at low er temperature.
Please check the characteristics of your inverter before applying to your set.
(Note 3) Average life time of CFL w ill be decreased w hen LCM is operating at low er temperature.
(Note 4) Under low er driving frequency of an inverter, a certain backlight system (CFL & CFL
reflection sheet) may generate a sound noise. Before designing the inverter, please
consider the driving frequency and the noise.
(Note 5) Under low er temperature, please check CFL characteristics on your inverter.

(1) To prevent the module cover from being pressed, the distance betw een the module and the
f itting plate, w hich means the lenght of the spacers, should be shorter than 1.0mm.
(2) We recommend you to use protective spacers in order to protect the module from any kinds of
shocks to your set.
(3) For the module to be used at upright position, the case shall have a structure w here the touch
panel screen does not shif t w ith its ow n w eight.

11.3 POWER ON SEQUENCE
Input signals should not be applied to LCD module before pow er supply voltage is applied and
reaches to specified voltage (3.0
0.15V).
If the above sequence is not kept, C-MOS LSIs of LCD module may be damaged due to latch up
phenomenon.
11.4 HANDLING PRECAUTIONS
(1) Since the polarizer on the top, and the aluminum plate on the bottom tend to be easily damaged,
they should be handled w ith full care so as not to get them touched, pushed or rubbed by a piece
on glass, tw eezers and anything else w hich are harder than a pencil lead 3H.
(2) As the adhesives used for adhering upper/low er polarizers and aluminum plate are made of
organic substances w hich w ill be deteriorated by a chemical reaction w ith such chemicals as
acetone, tuluene, ethanole and isopropylalcohol. The f ollow ing solvents are recommended for
use : Normal hexane
Please contact us w hen it is necessary f or you to use chemicals other than the above.
11.2 PRECAUTIONS AGAINST ELECTROSTATIC DISCHARGE
As this module contains C-MOS LSIs, it is not strong against electrostatic discharge.
Make certain that the operator's body is connected to the ground through a list band etc.
And don't touch I/F pins directly.
(5) The clearance betw een the touch panel and the case shall be designed so that the case edge
never presses the input screen w hen it is deformed by heat or other causes.
(6) The case shall be designed not to touch the tail portion (FPC for touch panel).
(4) When assembling the touch panel and your case, please refer to the figure below .

(3) Lightly w ipe to clean the dirty surface w ith absorbent cotton or other sof t material like chamois,
soaked in the recommended chemicals w ithout scrubbing it hardly.
Alw ays w ipe the surface horizontally or vertically. Never give a w ipe in a circle. To prevent
the display surface from damage and keep the appearance in good state, it is sufficient, in general,
to w ipe it w ith absorbent cotton.
(4) Immediately w ipe off saliva or w ater drop attached on the display area because it may cause
def ormation or faded color.
(5) Fogy dew deposited on the surface may cause a damage, stain or dirt to the polarizer.
When you need to take out the LCD module from some place at low temperature for test, etc.
It is required to be w armed them up to be temperature higher than room temperature before taking
them out.
(6) Touching the display area or I/F pins w ith bare hands or contaminating them are prohibited,
because the stain on the display area and poor insulation betw een terminals are often caused by
being touched w ith bare hands.
(Some cosmetics are detrimental to polarizers.)
(7) In general, the glass is fragile so that it, especially on its periphery, tends to be cracked or
chipped in handling. Please do not give the LCD module sharp shocks caused by falling etc.
(8) Maximum pressure to the surface must be less than 1.96
10
4
Pa (0.2kgf /cm
2
).
And if the pressure area is less than 1cm
2
, maximum pressure must be less than 1.96N (0.2kgf).
(9) Since the metal w idth is narrow on these locations (see page 9-1/2), please be careful w ith
handling.
(10) Top sheets shall be cleaned gently using a sof t cloth such as those used f or glasses.
Hard w iping accumulated dust w ill leave scars on the surface even using a cloth.
11.5 OPERATION PRECAUTION
(1) Using a LCM module beyond its maximum ratings may result in its permanent destruction.
LCM module's should usually be used under recommended operating conditions show n in
chapter 5. Exceeding any of these conditions may adversely affect its reliability.
(2) Response time w ill be extremely delayed at low er temperature than the specif ied operating
temperature range and on the other hand LCD's show s dark blue color at higher temperature.
How ever those phenomena do not mean def ects of the LCD module. Those phenomena w ill
disappear in the specified operating temperature range.
(3) If the display area is pushed hard during operation, some display patterns w ill be abnormally
displayed.

(4) A slight dew depositing on terminals may cause electrochemical reaction w hich leads to terminal
open circuit. Please operate the LCD module under the relative condition of 40
C 85%RH.
(5) Resistance renge : Your controller shall be set up to allow the resistance range of touch panel
specified in our CAS.
(6) Pointed position of touch panel may shift ow ing to a change in resistance of touch panel
depending on the operation condition. To compensate this shif t, the set shall be given a calibration
function.
(7) Input shall be made w ith a stylus pen (polyacetal, R0.8). Chances are very high that use of a
metal piece including a ball point pen or sharp edge w ill impair accuracy.
(8) The touch panel is an auxiliary input device. The system shall be designed to have other input
device.
11.6 STORAGE
In case of storing LCD module for a long period of time (for instance, for years) for the purpose of
replacement use, the follow ing precautions necessary.
(1) Store the LCD modules in a dark place ; do not expose them to sunlight or ultraviolet rays.
(2) Keep the temperature betw een 10
C and 35
C at normal humidity.
(3) Store the LCD modules in the container w hich is used for shipping from us.
(4) No articles shall be lef t on the surface over an extended period of time.
11.7 SAFETY
The LCD modules include Cold Cathode Fluorescent Lamp (CFL). CFL contains a small amount of
mercury. Please follow local ordinances or regulations for disposal.
Wear finger cots or gloves w henever handling or assembling a touch panel because its glass
edges are sharp.
