1. Application
This specification applies to a color TFT-LCD module, LQ070Y3LG4A.
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, power supply circuit, and a backlight unit. Graphics and texts can be
displayed on a 800×3×480 dots panel with 16,194,277 colors by using LVDS (Low Voltage Differential Signaling)
interface and supplying +3.3V DC supply voltage for TFT-LCD panel driving and supply voltage for backlight.
In this TFT-LCD panel , low reflection / color filters of excellent color performance and backlights of high brightness
are incorporated to realize brighter and clearer pictures, making this model optimum for use in multi-media applications.
Optimum viewing direction is 6 o'clock.
White-LED Backlight-driving DC/DC converter is not built in this module.

[Note 3] Definitions of viewing angle range:
[Note 4] Definition of contrast ratio:
The contrast ratio is defined as the following.
Contrast Ratio (CR) ＝
Luminance (brightness) with all pixels white
Luminance (brightness) with all pixels black
[Note 5] Definition of response time:
The response time is defined as the following figure and shall be measured by switching the input
signal for "black" and "white" .
[Note 6] This shall be measured at center of the screen.
10. Display Quality
The display quality of the color TFT-LCD module shall be in compliance with the Incoming Inspection Standard.
LD21705A-16
11．Handling Precautions
a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) Be sure to design the cabinet so that the module can be installed without any extra stress such as warp or twist.
c) Since the front polarizer is easily damaged, pay attention not to scratch it.
d) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.
e) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
f) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with care.
g) Since CMOS LSI is used in this module, take care of static electricity and injure the human earth when handling.
Observe all other precautionary requirements in handling components.
h) This module has its circuitry PCBs on the rear side and should be handled carefully in order not to be stressed.
i) Protect sheet is attached to the module surface to prevent it from being scratched. Peel the sheet off slowly just
before the use with strict attention to electrostatic charges. Ionized air shall be blown over during the action. Blow
off the 'dust' on the polarizer by using an ionized nitrogen gun, etc..
j) The polarizer surface on the panel is treated with Anti-Glare for low reflection. In case of attaching protective
board over the LCD, be careful about the optical interface fringe etc. which degrades display quality.
k) Do not expose the LCD module to a direct sunlight, for a long period of time to protect the module from the ultra
violet ray.
l) 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.
m) Liquid crystal contained in the panel may leak if the LCD is broken. Rinse it as soon as possible if it gets
inside your eye or mouth by mistake.
n) Disassembling the module can cause permanent damage and should be strictly avoided.
Please don't remove the fixed tape, insulating tape etc that was pasted on the original module.
(Except for protection film of the panel and the crepe tape (yellow tape) of fixing lamp
cable temporarily.)
o) Be careful when using it for long time with fixed pattern display as it may cause afterimage.
(Please use a screen saver etc., in order to avoid an afterimage.)
p) Adjusting volume have been set optimally before shipment, so do not change any adjusted value. If adjusted value
is changed, the specification may not be satisfied.
q) If a minute particle enters in the module and adheres to an optical material, it may cause display non-uniformity
issue, etc. Therefore, fine-pitch filters have to be installed to cooling and inhalation hole if you intend to install a
fan.
r) Epoxy resin (amine series curing agent), silicone adhesive material (dealcoholization series and oxime series),
tray forming agent (azo compound) etc, in the cabinet or the packing materials may induce abnormal display with
polarizer film deterioration regardless of contact or noncontact to polarizer film.
LD21705A-17
Be sure to confirm the component of them.
s) Do not use polychloroprene. If you use it, there is some possibility of generating Cl2 gas that influences the
reliability of the connection between LCD panel and driver IC.
t) Do not put a laminate film on LCD module, after peeling of the original one. If you put on it, because of the
occurrence of air gaps between the polarizer and the film, It may cause discoloration or spots.
