1. General Description
This specification applies to the 46 inch Color TFT-LCD Module T460HW03 V1. This LCD module has a TFT
active matrix type liquid crystal panel 1920x1080 pixels, and diagonal size of 46 inch. This module supports Full
HD mode (Non-interlace).
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 T460HW03 V1 has been designed to apply the 8-bit 2 channel LVDS interface method. It is intended to
support displays where high brightness, EBU Gamut (72% NTSC), wide viewing angle, and high color depth are
very important.
The T460HW03 V1 backlight unit is using inverter-less solution (inductor type balance board), and need to be
powered by integrated power system by customers.

3. Electrical Specification
The T460HW03 V1 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 integrate
power (I/P) system.

The performance of the Lamp in LCD panel, for example life time or brightness, is extremely influenced by
the characteristics of the balance board and I/P board. All the parameters should be carefully designed as
not to produce too much leakage current from high-voltage output. While design or order balance board,
please make sure unwanted lighting caused by the mismatch of the lamp and balance board (no lighting,
flicker, etc) never occurs. After confirmation, the LCD Panel 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 has a low luminance and the inverter has abnormal action, because leakage current
occurs between lamp wire and conducting tape.
When operate at low temperatures, the brightness of CCFL will drop and the lifetime of CCFL will be
reduced.

3.5 Color Input Data Reference
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

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

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 on back side of panel
(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.
(7) The device listed in the product specification sheets was designed and manufactured for TV application.

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°C and 35°C 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.
