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 and power supply circuit and a backlight unit. Graphics and texts can be
displayed on a 640×3×480 dots panel with 262,144 colors by supplying 18 bit data signal

(6bit/color), four timing signals,+3.3V/ +5V DC supply voltage for TFT-LCD panel driving and
supply voltage for backlight.
The TFT-LCD panel used for this module is a low-reflection and higher-color-saturation
type. Therefore, this module is also suitable for the multimedia use.
Optimum viewing direction is 6 o'clock.
Backlight-driving DC/AC inverter is not built in this module.

Note1 Lamp current is measured with current meter for high frequency as shown below.

Note2 At the condition of I

=6.0mArms

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.
Note4The open output voltage of the inverter shall be maintained for more than 1sec; otherwise
the lamp may not be turned on.
Note5Since lamp is consumables, the life time written above is referencial value and it is not
guaranteed in this specification sheet by SHARP.
Lamp life time is defined that it applied either or under this condition
(Continuous turning on at Ta=25, IL=6.0mArms)
Brightness becomes 50% of the original value under standard condition.
Kick-off voltage at Ta=-10 exceeds maximum value,(1500)Vrms.
In case of operating under lower temp environment, the lamp exhaustion is accelerated and the
brightness becomes lower.
(Continuous operating under for around 1 month under lower temp condition may reduce the
brightness to half of the original brightness.)
In case of such usage under lower temp environment, periodical lamp exchange is recommended.
Note6The performance of the backlight, 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 backlight and
the inverter (miss-lighting,flicker, etc.) never occur. when you confirm it, the module should
be operated in the same condition as it is installed in your instrument.
Note7 It is required to have the inverter designed so that to allow the impedance deviation
of the two CCFT lamps and the capacity deviation of barast capacitor.

Note) When ENAB is fixed "Low", the display starts from the data of C104(clock) as shown
in Fig.2-. Be careful that the module does not work when ENAB is fixed "High".

When the phase difference is below 104 clock, keep the "High level of ENAB is signal longer

Than 104-The. If it will not be keeped, the display starts from the data of C104(clock).

7-3. Vertical display position

The vertical display position is automatically centered in the active area at each mode

LD14702-8

of VGA ,480-,400-,and 350-line mode . Each mode is selected depending on the polarity of

the synchronous signals described in 4-1(Note1).

In each mode ,the data of TVn is displayed at the top line of the active area. And the

display position will be centered on the screen like the following figure when the period of

vertical synchronous signal,TV,is typical value.

In 400-,and 350-line mode,the data in the vertical data invalid period is also displayed,

So ,inputting all data "0" is recommended during vertical data invalid period.

ENAB signal has no relation to the vertical display position.

10. Display Quantity

The display quality of the color TFT-LCD module shall be in compliance with the

Incoming Inspection Standard.

11Handling 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.

h) Laminated film is attached to the module front and back surface to prevent it from being scratched .

Peel the film off slowly , just before the use, with strict attention to electrostatic charges. Ionized

air shall be blown over during the action. Blow off 'dust' on the polarizer by using an ionized nitrogen

. i) 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.

j)Do not expose the LCD panel to direct sunlight. Lightproof shade etc. should beattached when LCD panel is

used under such environment.

k) Connect GND to 4 place of mounting holes to stabilize against EMI and external noise.

l) There are high voltage portions on the backlight and very dangerous. Careless touch may lead to

electrical shock. When exchange lamps or service. Turn off the power without tail.

m) 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.

n)Cold cathode fluorescent lamp in LCD panel contains a small amount of mercury, please follow local

ordinances or regulations for disposal.
