the TFT array and liquid crystal. An inverter typically generates the second input, which powers the
CCFL.

The performance of the Lamp in LCM, for example lifetime or brightness, is extremely influenced by
the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be carefully
www.jxlcd.com
www.jxlcd.com
designed so as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch
of the lamp and the inverter (no lighting, flicker, etc) never occurs. When you confirm it, the LCD
Assembly should be operated in the same condition as installed in your instrument.
Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to conducting tape,
TFT-LCD Module have a low luminance and the inverter has abnormal action because leakage
current occurs between lamp wire and conducting tape.
The relative humidity must not exceed 80% non-condensing at temperatures of 40 ℃ or less. At
temperatures greater than 40℃, the wet bulb temperature must not exceed 39℃. When operate at
low temperatures, the brightness of CCFL will drop and the lifetime of CCFL will be reduced.
This is the signal timing required at the input of the User connector. All of the interface signal
timing should be satisfied with the following specifications for it’s proper operation.

1.) Display position is specific by the rise of DE signal only.
Horizontal display position is specified by the rising edge of 1st DCLK after the rise of 1st DE, is
displayed on the left edge of the screen.
Vertical display position is specified by the rise of DE after a “Low” level period equivalent to eight

times of horizontal period. The 1st data corresponding to one horizontal line after the rise the of 1st DE
is displayed at the top line of screen.
3.) If a period of DE “High” is less than 1366 DCLK or less than 768 lines, the rest of the screen
displays black.
4.) The display position does not fit to the screen if a period of DE “High” and the effective data period
do not synchronize with each other.
The brightness of each primary color (red, green and blue) is based on the 8 bit gray scale data input
for the color; the higher the binary input, the brighter the color. The table below provides a reference for
color versus data input.

Apply the lamp voltage within the LCD operating range. When the backlight turns on before the LCD
operation or the LCD turns off before the backlight turns off, the display may momentarily become
abnormal.

case of handling, make sure to turn off the power when you plug the cable into the input connector or
pull the cable out of the connector.
Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 30 minutes
in a dark environment at 25℃. The values specified are at an approximate distance 50cm from the LCD
surface at a viewing angle of Φ and θequal to 0°.

1. Contrast Ratio (CR) is defined mathematically as:
2. Surface luminance is luminance value at point 1 across the LCD surface 50cm from the surface with
all pixels displaying white. From more information see FIG 4-2. When IBL = 6.5mA, LWH=450cd/㎡
(typ.) LWH=Lon1, Where Lon1 is the luminance with all pixels displaying white at center 1 location.

4. Response time is the time required for the display to transition from white(L255) to black(L0) (Decay
Time, TrD=Tf ) and from black(L0) to white(L255) (Rise Time, TrR=Tr ). The response time interval is
between the 10% and 90% of 1st frame amplitudes. For additional information see FIG 4-3.
5. Viewing angle is the angle at which the contrast 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 4-5.

Please pay attention to the followings when you use this TFT LCD module.
8-1 MOUNTING PRECAUTIONS
(1) You must mount a module using holes arranged in four corners or four sides.
(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not
applied to module. And the case on which a module is mounted should have sufficient strength so
that external force is not transmitted directly to the module.
(3) Please attach the surface transparent protective plate to the surface in order to protect the
polarizer. Transparent protective plate should have sufficient strength in order to the resist external
force.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the
former generates corrosive gas of attacking the polarizer at high temperature and the latter causes
circuit break by electro-chemical reaction.
(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than
HB pencil lead. And please do not rub with dust clothes with chemical treatment. Do not touch the
surface of polarizer for bare hand or greasy cloth. (Some cosmetics are detrimental to the
polarizer.)
www.jxlcd.com
www.jxlcd.com
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft
materials like chamois soaks with petroleum benzene. Normal-hexane is recommended for
cleaning the adhesives used to attach front/ rear polarizers. Do not use acetone, toluene and
alcohol because they cause chemical damage to the polarizer.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer
causes deformations and color fading.
(9) Do not open the case because inside circuits do not have sufficient strength.
8-2 OPERATING PRECAUTIONS
(1) The spike noise causes the mis-operation of circuits. It should be lower than following
voltage: V=±200mV(Over and under shoot voltage)
(2) Response time depends on the temperature. (In lower temperature, it becomes
longer..)
(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.) And
in lower temperature, response time (required time that brightness is stable after turned
on) becomes longer.
(4) Be careful for condensation at sudden temperature change. Condensation makes
damage to polarizer or electrical contacted parts. And after fading condensation, smear
or spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic
interference shall be done by system manufacturers. Grounding and shielding methods
may be important to minimize the interface.
8-3 ELECTROSTATIC DISCHARGE CONTROL
Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make
certain that treatment persons are connected to ground through wrist band etc. And don ’t touch
interface pin directly.
8-4 PRECAUTIONS FOR STRONG LIGHT EXPOSURE
Strong light exposure causes degradation of polarizer and color filter.
8-5 STORAGE
When storing modules as spares for a long time, the following precautions are necessary.
(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the
temperature between 5℃ and 35℃ at normal humidity.
www.jxlcd.com
www.jxlcd.com
(2) The polarizer surface should not come in contact with any other object. It is recommended that
they be stored in the container in which they were shipped.
8-6 HANDLING PRECAUTIONS FOR PROTECTION FILM
(1) The protection film is attached to the bezel with a small masking tape. When the protection film is
peeled off, static electricity is generated between the film and polarizer. This should be peeled off
slowly and carefully by people who are electrically grounded and with well ion-blown equipment or
in such a condition, etc.
(2) When the module with protection film attached is stored for a long time, sometimes there remains
a very small amount of flue still on the Bezel after the protection film is peeled off.
(3) You can remove the glue easily. When the glue remains on the Bezel or its vestige is recognized,
please wipe them off with absorbent cotton waste or other soft material like chamois soaked with
normal-hexane.
