1. Application
This specification applies to the color 42” TFT-LCD module LQ420D3LZ19.
* These specification sheets are proprietary products of SHARP CORPORATION (“SHARP”) and include materials
protected under copyright of SHARP. Do not reproduce or cause any third party to reproduce them in any form or by
any means, electronic or mechanical, for any purpose, in whole or in part, without the express written permission of
SHARP.
* In case of using the device for applications such as control and safety equipment for transportation (aircraft, trains,
automobiles, etc.), rescue and security equipment and various safety related equipment which require higher
reliability and safety, take into consideration that appropriate measures such as fail-safe functions and redundant
system design should be taken.
* Do not use the device for equipment that requires an extreme level of reliability, such as aerospace applications,
telecommunication equipment (trunk lines), nuclear power control equipment and medical or other equipment for
life support.
* SHARP assumes no responsibility for any damage resulting from the use of the device that does not comply with
the instructions and the precautions specified in these specification sheets.

2. Overview
This module is a color active matrix LCD module incorporating amorphous silicon TFT (T
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 1920×RGB×1080 dots panel with 16,777,216 colors by
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.
By using the captioned process, the image signals of this LCD module are being set so that image response can be
completed within one frame, as a result, image blur can be improved and clear image performance can be realized.

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, ΔV
INV,
inverter and its surrounding circuit. So, separate the power supply of the inverter circuit with the one of its
surrounding circuit.

*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.
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) Lamps of the backlight are placed horizontally to the short side of LCD module. So make sure that the LCD
module are placed horizontally (landscape position), as lifetime of backlight becomes shorter if placed at
atilt.
p) Make sure that the LCD module is operated within specified temperature and humidity.Measures against dust,
water, vibration, and heat radiation, etc. are required at the cabinet or equipment side.And image retention
may occur if same fixed pattern is displayed for a long time. In some cases, it may notdisappear.
Please consider the design and operating environment
11. Packing form
a) Piling number of cartons: 2 maximum
b) Packing quantity in one carton: 4 pcs.
