1. General Description
This specification applies to the 20.1 inch Color TFT-LCD Module T201VN02 V0. This LCD module
has a TFT active matrix type liquid crystal panel 640x480 pixels, and diagonal size of 20.1 inch. This
module supports 640x480 VGA mode (Non-interlace). This module is without inverter.
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the brightness of the sub-pixel color is determined with a 8-bit gray scale signal for each
dot.
The T201VN02 V0 has been designed to apply the 8-bit TTL interface method. It is intended to support
displays where high brightness, wide viewing angle, high color saturation, and high color depth are
very important.

3. Electrical Specification
3-1 Electrical Characteristics
The T201VN02 V0 requires two power inputs. One is employed to power the LCD electronics and
to drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically
generated by an inverter.

The design of the inverter must have specifications for the lamp in LCD Assembly. The performance of
the Lamp in LCM, for example life time or brightness, is extremely influenced by the characteristics of
the DC-AC Inverter. So all the parameters of an inverter should be carefully 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.

Unit Notes
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 40or 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 life time of CCFL will be reduced.

Note1 : The specified current and power consumption are under the Vcc=5.0V, 25, fv= 60Hz,
fCLK=25.2Mhz condition whereas mosaic pattern (8x6) is displayed and fv is the frame
frequency.
Note2 : The lamp power consumption shown above does include loss of external inverter at 25
. The used lamp current is the lamp typical current
Note3 : The life is determined as the time at which luminance of the lamp is 50% compared to
that of initial value at the typical lamp current on condition of continuous operating at 25
2. The lamp current should fix in 4.2mA(typ.) and then keep the 60000hr(typ.) lamp
life
The output of the inverter must have symmetrical (negative and positive) voltage waveform and
symmetrical current waveform (Asymmetry ratio is less than 10%). Please do not use the inverter
which has asymmetrical voltage and asymmetrical current and spike wave.
Requirements for a system inverter design which is intended to have a better display
performance, a better power efficiency and a more reliable lamp.
It shall help increase the lamp lifetime and reduce its leakage current.
a. The asymmetry rate of the inverter current and voltage waveform should be 10%
below;
b. The distortion rate of the current and voltage waveform should be within 210%;
c. The ideal sine current and voltage waveform shall be symmetric in positive and
negative polarities.

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.
Caution : The above on/off sequence should be applied to avoid abnormal function in the display. In
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.
Note1 : The 450ms timing is separated into 2 parts and each one has following characteristic:
0~200ms : If t3 setting is in this timing period, it will have the risk of abnormal display

8. PRECAUTIONS
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.)
(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.
(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.
