This specification applies to the 37.0 inch Color TFT-LCD Module T370HW05 V2. This LCD module has a TFT
active matrix type liquid crystal panel 1,920x1,080 pixels, and diagonal size of 37.0 inch. This module supports
1,920 x1,080 mode. 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 10-bit gray scale signal for
each dot.
The T370HW05 V2 has been designed to apply the 10-bit 4 channel LVDS interface method. It is intended to
support displays where high brightness, wide viewing angle, high color saturation, and high color depth are very
important.

Please pay attention to the followings when you use this TFT LCD module.
9-1 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
Rev. 00
generates corrosive gas of attacking the polarizer at high temperature and the latter cause circuit
broken by electro-chemical reaction.
(6) Do not touch, push or rub the exposed polarizer 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 polarizer. 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.
9-2 OPERATING PRECAUTIONS
(1) The device listed in the product specification sheets was designed and manufactured for TV
application
(2) The spike noise causes the mis-operation of circuits. It should be lower than following voltage:
V=±200mV(Over and under shoot voltage)
(3) Response time depends on the temperature. (In lower temperature, it becomes longer..)
(4) Brightness of CCFL 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.
(5) 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.
(6) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(7) 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.
9-3 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 wristband etc. And don’t touch interface pin
directly.
9-4 PRECAUTIONS FOR STRONG LIGHT EXPOSURE
Strong light exposure causes degradation of polarizer and color filter.
9-5 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
T370HW05 V2 Product Specification
Rev. 00
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.
9-6 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 glue 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
