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 640×RGB×480 dots panel with 262,144 colors

by supplying data signal of 18 bit(6 bit x RGB), 4 kinds of timing signal, +5V of DC supply voltages and supply

voltage for back light.

This module also includes the DC/AC inverter to drive the CCFT lamps.

10. Display Quality

The display quality of the color TFT-LCD module shall be compliance with the incoming inspection standard.

11. Warning

The module includes the inverter circuit, which generates high voltage. Do not touch the inverter cover and

CCFT lamp terminals in current carrying. Clearly, alert the possibility of the inverter touched by someone.

12. Handling Precautions of the module

a) Be sure to turn off the power supply when inserting or disconnecting the cable.

b) Brightness control voltage is switched for “ON” and “OFF”, as shown in Fig.4. Voltage difference generated

by this switching, ΔVINV, may affect a sound output, etc. when the power supply is shared between the

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

surrounding circuit.

c) Be sure to fix the module in the same plane so that the module can be installed without any extra stress such

as warp or twist.

d) Since the front polarizer is easily damaged, pay attention to treat it.

e) Since long contact with water may cause discoloration or spots, wipe off water drop immediately.

f) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.

g) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with

care.

h) Since CMOS LSI is used in this module, take care of static electricity and consider wearing the earth

personnel when handling.

i) Observe all other precautionary requirements in handling components.

j) Blow off dust with N2 blower for which static electricity preventive measure has been taken. Ionized air gun

is recommended.

12. Packing form

a) Piling number of cartons: 4 (maximum)

b) Packing quantity in one carton: 2

c) Carton size: 393mm(W) x 293mm(H) x 515mm(D)

2) 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.

3) Disassembling the module can cause permanent damage and should be strictly avoided.

4) Please be careful since image retention may occur when a fixed pattern is displayed for a long time.

5) Be sure to turn off the power supply of the inverter circuit before turning off the one of the control circuit.

6) Rust on the module is not taken up as a problem.

7) When any question or issue occurs, it shall be solved by mutual discussion.
