2. Overview
This module is a color active matrix LCD module incorporating amorphous silicon TFT (Thin Film Transistor). It is
composed of a color TFT-LCD panel, driver ICs, control circuit, power supply circuit, inverter circuit and back light
system etc. Graphics and texts can be displayed on a 1920RGB1080 dots panel with
using LVDS (L
This module also includes the DC/AC inverter to drive the CCFT. (+24V of DC supply voltage)
And in order to improve the response time of LCD, this module applies the Over Shoot driving (O/S driving)
technology for the control circuit .In the O/S driving technology, signals are being applied to the Liquid Crystal
according to a pre-fixed process as an image signal of the present frame when a difference is found between image
signal of the previous frame and that of the current frame after comparing them.
With this technology, image signals can be set so that liquid crystal response completes within one frame. As a
result, motion blur reduces and clearer display performance can be realized.

Life time TL - 60000 - Hour [Note]
[Note]
x Lamp life time is defined as the time when brightness becomes 50% of the original value in the continuous
operation under the condition of Ta=25qC and brightness control=100%.
x Above value is applicable when the long side of LCD module is placed horizontally (Landscape position).
(Lamp lifetime may vary if LCD module is in portrait position due to the change of mercury density inside
the lamp.)

[Note]About the relation between data input and back light lighting, please base on the above-mentioned input
sequence. When back light is switched on before panel operation or after a panel operation stop, it may not
display normally. But this phenomenon is not based on change of an incoming signal, and does not give
damage to a liquid crystal display.

10. Handling Precautions of the module
a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) This product is using the parts (inverter, CCFT etc), which generate the high voltage.
Therefore, during operating, please don't touch these parts.
c) Brightness control voltage is switched for “ON” and “OFF”, as shown in Fig.4. Voltage difference generated
by this switching, 'V
inverter and its surrounding circuit. So, separate the power supply of the inverter circuit with the one of its
surrounding circuit.
INV, may affect a sound output, etc. when the power supply is shared between the

*Since inverter board’s GND is not connected to the frame of the LCD module, please connect it with the
Customer’s GND of inverter power supply.
d) Be sure to design the cabinet so that the module can be installed without any extra stress such as warp or
twist.
e) Since the front polarizer is easily damaged, pay attention not to scratch it.
f) Since long contact with water may cause discoloration or spots, wipe off water drop immediately.
g) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
h) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with
care.

Global LCD Panel Exchange Center
i) Since CMOS LSI is used in this module, take care of static electricity and take the human earth into
consideration when handling.
j) The module has some printed circuit boards (PCBs) on the back side, take care to keep them form any stress
or pressure when handling or installing the module; otherwise some of electronic parts on the PCBs may be
damaged.
k) Observe all other precautionary requirements in handling components.
l) When some pressure is added onto the module from rear side constantly, it causes display non-uniformity
issue, functional defect, etc. So, please avoid such design.
m) When giving a touch to the panel at power on supply, it may cause some kinds of degradation. In that case,
once turn off the power supply, and turn on after several seconds again, and that is disappear.
n) When handling LCD modules and assembling them into cabinets, please be noted that long-term storage in
the environment of oxidization or deoxidization gas and the use of such materials as reagent, solvent,
adhesive, resin, etc. which generate these gasses, may cause corrosion and discoloration of the LCD
modules.
o) This LCD module is designed to prevent dust from entering into it. However, there would be a possibility to
have a bad effect on display performance in case of having dust inside of LCD module. Therefore,
please ensure to design your TV set to keep dust away around LCD module.
