1. Application
This specification applies to the color 18.1 SXGA TFT-LCD module LQ0DZA1003.

The device listed in these specification sheets was designed and manufactured for use in OA equipment.

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.

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 and a back
light unit. Graphics and texts can be displayed on a 1280 3 1024 dots panel with about 16 million colors (8 bit)
by supplying 48 bit data signals(8bit 2pixel RGB) or 96 bit data signals(8bit 4pixel RGB), two display
enable signals, two dot clock signals, +5V DC and +15V DC supply voltages for TFT-LCD panel driving and

6-2. Back light driving
The back light system is an edge-lighting type with four CCFTs (Cold Cathode Fluorescent Tube). The
characteristics of the lamp are shown in the following table. The value mentioned below is at the case of
one CCFT.
Parameter Symbol Min. Typ. Max. Unit Remark
Lamp current range IL 6.5 7.5 mArms Note1
Lamp voltage VL 715 Vrms Ta=25
Lamp power consumption PL 4.65 W Note2
Lamp frequency FL 50 60 70 KHz Note3
Kick-off voltage Vs 1250 Vrms Ta=25 Note4
1600 Vrms Ta=0 Note4
Lamp life time TL 50000 hour Note5

Note1 A lamp can be light in the range of lamp current shown above.
Maximum rating for current is measured by high frequency current measurement equipment
connected to VLOW at circuit showed below. (Note : To keep enough kick-off voltage and necessary
steady voltage for CCFT.)
Lamp frequency : 50 70kHz
Ambient temperature : 0 50

Note2 Referential data per one CCFT by calculation ( IL VL ) .
The data don't include loss at inverter.
Note3 Lamp frequency may produce interference with horizontal synchronous frequency, and this may
cause beat on the display. Therefore lamp frequency shall be detached as much as possible from the
horizontal synchronous frequency and from the harmonics of horizontal synchronous to avoid
interference.
Note4 The voltage above this value should be applied to the lamp for more than 1 second to startup.
Otherwise the lamp may not be turned on.
Note5 Lamp life time is defined as the time when either or occurs in the continuous operation under
the condition of Ta=25 and IL=6.5 mArms.
Brightness becomes 50% of the original value under standard condition.
Kick-off voltage at Ta=0 exceeds maximum value, 1600 Vrms.
Note The performance of the back light, for example life time or brightness, is much influenced by the
characteristics of the DC-AC inverter for the lamp. When you design or order the inverter, please make sure that a
poor lighting caused by the mismatch of the back light and the inverter (miss-lighting, flicker, etc.) never occurs.
When you confirm it, the module should be operated in the same condition as it is installed in your instrument.
