Note 1. Contrast Ratio(CR) is defined mathematically as For more information see FIG 2.:
Contrast Ratio =
Average Surface Luminance with all white pixels (P 1,P2, P 3,P4, P5)
Average Surface Luminance with all black pixels (P1, P2, P 3,P4, P5)
Note 2. Surface luminance is the LCD surface from the surface with all pixels displaying white. For
more information see FIG 2.
Lv = Average Surface Luminance with all white pixels (P1, P2, P 3,P4, P5)
Note 3. The uniformity in surface luminance , d WHITE is determined by measuring luminance at each
test position 1 through 5, and then dividing the maximum luminance of 5 points luminance by minimum
luminance of 5 points luminance. For more information see FIG 2.
d WHITE = Minimum Surface Luminance with all white pixels (P1, P2, P 3,P4,
P5)
Maximum Surface Luminance with all white pixels (P1, P2, P 3,P4, P5)
Note 4. Response time is the time required for the display to transition from White to black(Rise Time, Tr)
and from black to white(Decay Time, Tf). For additional information see FIG 1. The test equipment is
Autronic-Melchers’s ConoScope. series
Note 5. CIE (x, y) chromaticity,The x,y value is determined by measuring luminance at each test position
1 through 5,and then make average value
Note 6. Viewing angle is the angle at which the contrast ratio is greater than 2. For TFT module the
conrast ratio is greater than 10. The angles are
determined for the horizontal or x axis and the
vertical or y axis with respect to the z axis which is normal to the LCD surface. For more information
see FIG 3.
Note7. For Viewing angle and response time testing, the testing data is base on Autronic-Melchers’s
ConoScope. Series Instruments. For contrast ratio, Surface Luminance, Luminance uniformity,CIE The
test data is base on TOPCON’s BM-5 photo detector.

Remark:
1.The test samples should be applied to only one test item.
2.Sample size for each test item is 5~10pcs.
3.For Damp Proof Test, Pure water(Resistance＞10MΩ) should be used.
4.In case of malfunction defect caused by ESD damage, if it would be recovered to normal
state after resetting, it would be judge as a good part.
Using ionizer(an antistatic blower) is recommended at working area in order to reduce
electro-static voltage.
When removing protection film from LCM panel, peel off the tag slowly( recommended
more than one second) while blowing with ionizer toward the peeling face to minimize ESD
which may damage electrical circuit.
5.EL evaluation should be excepted from reliability test with humidity and temperature: Some
defects such as black spot/blemish can happen by natural chemical reaction with humidity and
Fluorescence EL has.
6.Please use automatic switch menu(or roll menu) testing mode when test operating mode

n PRECAUTIONS FOR USING LCD MODULES
Handing Precautions
(1) The display panel is made of glass and polarizer. As glass is fragile. It tends to become or chipped
during handling especially on the edges. Please avoid dropping or jarring. Do not subject it to a
mechanical shock by dropping it or impact.
(2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in
your mouth. If the substance contacts your skin or clothes, wash it off using soap and water.
(3) Do not apply excessive force to the display surface or the adjoining areas since this may cause the
color tone to vary. Do not touch the display with bare hands. This will stain the display area and degraded
insulation between terminals (some cosmetics are determined to the polarizer).
(4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle
this polarizer carefully. Do not touch, push or rub the exposed polarizers with anything harder than an HB
pencil lead (glass, tweezers, etc.). Do not put or attach anything on the display area to avoid leaving
marks on. Condensation on the surface and contact with terminals due to cold will damage, stain or dirty
the polarizer. After products are tested at low temperature they must be warmed up in a container before
coming is contacting with room temperature air.
(5) If the display surface becomes contaminated, breathe on the surface and gently wipe it with a soft
dry cloth. If it is heavily contaminated, moisten cloth with one of the following solvents
- Isopropyl alcohol
- Ethyl alcohol
Do not scrub hard to avoid damaging the display surface.
(6) Solvents other than those above-mentioned may damage the polarizer. Especially, do not use the
following.
- Water
- Ketone
- Aromatic solvents
Wipe off saliva or water drops immediately, contact with water over a long period of time may cause
deformation or color fading. Avoid contacting oil and fats.
(7) Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by
water droplets, moisture condensation or a current flow in a high-humidity environment.
(8) Install the LCD Module by using the mounting holes. When mounting the LCD module make
sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/O cable
or the backlight cable.
(9) Do not attempt to disassemble or process the LCD module.
(10) NC terminal should be open. Do not connect anything.
(11) If the logic circuit power is off, do not apply the input signals.
(12) Electro-Static Discharge Control，Since this module uses a CMOS LSI, the same careful
attention should be paid to electrostatic discharge as for an ordinary CMOS IC. To prevent destruction of
the elements by static electricity, be careful to maintain an optimum work environment.
- Before remove LCM from its packing case or incorporating it into a set, be sure the module and
your body have the same electric potential. Be sure to ground the body when handling the LCD modules.
- Tools required for assembling, such as soldering irons, must be properly grounded. make
certain the AC power source for the soldering iron does not leak. When using an electric screwdriver to
attach LCM, the screwdriver should be of ground potentiality to minimize as much as possible any
transmission of electromagnetic waves produced sparks coming from the commutator of the motor.
- To reduce the amount of static electricity generated, do not conduct assembling and other work
under dry conditions. To reduce the generation of static electricity be careful that the air in the work is not
too dried. A relative humidity of 50%-60% is recommended. As far as possible make the electric potential
of your work clothes and that of the work bench the ground potential
- The LCD module is coated with a film to protect the display surface. Exercise care when
peeling off this protective film since static electricity may be generated

Storage Precautions
When storing the LCD modules, the following precaution is necessary.
(1) Store them in a sealed polyethylene bag. If properly sealed, there is no need for the dessicant.
(2) Store them in a dark place. Do not expose to sunlight or fluorescent light, keep the temperature
between 0°C and 35°C, and keep the relative humidity between 40%RH and 60%RH.
(3) The polarizer surface should not come in contact with any other objects. (We advise you to store
them in the anti-static electricity container in which they were shipped.
Others
Liquid crystals solidify under low temperature (below the storage temperature range) leading to
defective orientation or the generation of air bubbles (black or white). Air bubbles may also be generated
if the module is subject to a low temperature.
If the LCD modules have been operating for a long time showing the same display patterns, the
display patterns may remain on the screen as ghost images and a slight contrast irregularity may also
appear. A normal operating status can be regained by suspending use for some time. It should be noted
that this phenomenon does not adversely affect performance reliability.
To minimize the performance degradation of the LCD modules resulting from destruction caused by
static electricity etc., exercise care to avoid holding the following sections when handling the modules.
- Exposed area of the printed circuit board.
-Terminal electrode sections.
n USING LCD MODULES
Installing LCD Modules
The hole in the printed circuit board is used to fix LCM as shown in the picture below. Attend to the
following items when installing the LCM.
(1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
(2) When assembling the LCM into other equipment, the spacer to the bit between the LCM and the
fitting plate should have enough height to avoid causing stress to the module surface, refer to the
individual specifications for measurements. The measurement tolerance should be ±0.1mm.
Precaution for assemble the module with BTB connector:
Please note the position of the male and female connector position, don’t assemble or assemble like
the method which the following picture shows

(1) If soldering flux is used, be sure to remove any remaining flux after finishing to soldering operation.
(This does not apply in the case of a non-halogen type of flux.) It is recommended that you protect the
LCD surface with a cover during soldering to prevent any damage due to flux spatters.
(2) When soldering the electroluminescent panel and PC board, the panel and board should not be
detached more than three times. This maximum number is determined by the temperature and time
conditions mentioned above, though there may be some variance depending on the temperature of the
soldering iron.
(3) When remove the electroluminescent panel from the PC board, be sure the solder has completely
melted, the soldered pad on the PC board could be damaged.
Precautions for Operation
(1) Viewing angle varies with the change of liquid crystal driving voltage (VLCD). Adjust VLCD to
show the best contrast.
(2) It is an indispensable condition to drive LCD's within the specified voltage limit since the higher
voltage then the limit cause the shorter LCD life. An electrochemical reaction due to direct current
causes LCD's undesirable deterioration, so that the use of direct current drive should be avoided.
(3) Response time will be extremely delayed at lower temperature than the operating temperature
range and on the other hand at higher temperature LCD's show dark color in them. However those
phenomena do not mean malfunction or out of order with LCD's, Which will come back in the specified
operating temperature.
(4) If the display area is pushed hard during operation, the display will become abnormal. However, it
will return to normal if it is turned off and then back on.
(5) A slight dew depositing on terminals is a cause for electro-chemical reaction resulting in terminal
open circuit. Usage under the maximum operating temperature, 50%RH or less is required.
(6) Input each signal after the positive/negative voltage becomes stable.
(7) Please keep the temperature within specified range for use and storage. Polarization degradation,
bubble generation or polarizer peel-off may occur with high temperature and high humidity.
