Liquid Crystal Display LC104S1-A1

1. General Description

The

LC104S1-A1

is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent

Lamp(CCFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transflective type

(1)

display operating in the normally white mode. This TFT-LCD has 10.4 inches

diagonally measured active display area with SVGA resolution(600 vertical by 800 horizontal pixel array)
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot,
thus, presenting a palette of more than 262,144 colors.
The LC104S1-A1 has been designed to apply the interface method that enables low power. Flat Link
must be used as a LVDS(Low Voltage Differential Signaling) chip.
The LC104S1-A1 is intended to support applications where thin thickness, low power are critical factors
and graphic display are important. In combination with the vertical arrangement of the sub-pixels, the
LC104S1-A1 characteristics provide an excellent flat display for office automation products such as
Tough PC.
(ref. No. 1 : Transflective type means that has a function of transmissive and reflective mode in display and

display is visible indoor or outdoor under dark and sunlight at all.)

Electrical Specifications

3-1. Electrical Characteristics

The LC104S1-A1 requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated
by an inverter. The inverter is an external unit to the LCD.

Note : The design of the inverter must have specification for the lamp in LCD Assembly.

The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by the
characteristics of the DC-AC inverter. So all the parameters of an inverter should be carefully designed
so as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of
the lamp and the inverter (no lighting, flicker, etc) never occurs. When you confirm it, the LCD Assembly
should be operated in the same condition as installed in you instrument.

1. The specified current and power consumption are under the V

=3.3V, 25

�

C,f

=60Hz condition

whereas Mosaic pattern is displayed and f

is the frame frequency.

2. This impedance value is needed to proper display and measured from LVDS T

to the mating connector.

3. The variance of the voltage is 10%.
4. The voltage above V

should be applied to the lamps for more than 1 second for start-up.

Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.

5. The output of the inverter must have symmetrical (negative and positive) voltage waveform and

symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter
which has unsymmetrical voltage and unsymmetrical current and spike wave.
Lamp frequency may produce interface with horizontal synchronous frequency and as a result this may
cause beat on the display. Therefore lamp frequency shall be as away possible from the
horizontal synchronous frequency and from its harmonics in order to prevent interference.

6. Let's define the brightness of the lamp after being lighted for 5 minutes as 100%.

is the time required for the brightness of the center of the lamp to be not less than 95%.

7. The lamp power consumption shown above does not include loss of external inverter.

The used lamp current is the lamp typical current.

8. The life is determined as the time at which brightness of the lamp is 50% compared to that of initial

value at the typical lamp current on condition of continuous operating at 25

�

9. Do not attach a conducting tape to lamp connecting wire.

If the lamp wire attach to a conducting tape, TFT-LCD Module has a low luminance and the inverter
has abnormal action. Because leakage current is occurred between lamp wire and conducting tape.

9. PRECAUTIONS

Please pay attention to the following when you use this TFT LCD module.

9-1. MOUNTING PRECAUTIONS

(1) You must mount a module using holes arranged in four corners or four sides.
(2) You should consider the mounting structure so that uneven force(ex. Twisted stress) is not applied

to the module.
And the case on which a module is mounted should have sufficient strength so that external force
is not transmitted directly to the module.

(3) Please attach a transparent protective plate to the surface in order to protect the polarizer.

Transparent protective plate should have sufficient strength in order to the resist external force.

(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not describe because the former

generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit
break by electro-chemical reaction.

(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB

pencil lead. And please do not rub with dust clothes with chemical treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth. (Some cosmetics are determined
to the polarizer.)

(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials

like chamois soaks with petroleum benzene. Normal-hexane is recommended for cleaning the
adhesives used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because
they cause chemical damage to the polarizer.

(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes

deformations and color fading.

(9) Do not open the case because inside circuits do not have sufficient strength.

9-2. OPERATING PRECAUTIONS

(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage :

V =

�

200 mV (Over and under shoot voltage)

(2) Response time depends on the temperature. (In lower temperature, it becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.)

And in lower temperature, response time (required time that brightness is stable after turned on)
becomes longer.

(4) Be careful for condensation at sudden temperature change. Condensation makes damage to

polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur.

(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference

shall be done by system manufacturers. Grounding and shielding methods may be important to
minimized the interference.

SPECIFICATION

Liquid Crystal Display LC104S1-A1

Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain
that treatment persons are connected to ground through wrist band etc. And don't touch interface pin directly.

9-3. ELECTROSTATIC DISCHARGE CONTROL

Strong light exposure causes degradation of polarizer and color filter.

9-4. PRECAUTIONS FOR STRONG LIGHT EXPOSURE

When storing modules as spares for a long time, the following precautions are necessary.

(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the

temperature between 5

�

C and 35

�

C at normal humidity.

(2) The polarizer surface should not come in contact with any other object.

It is recommended that they be stored in the container in which they were shipped.

9-5. STORAGE

(1) When the protection film is peeled off, static electricity is generated between the film and polarizer.

This should be peeled off slowly and carefully by people who are electrically grounded and with well
ion-blown equipment or in such a condition, etc.

(2) The protection film is attached to the polarizer with a small amount of glue. If some stress is applied

to rub the protection film against the polarizer during the time you peel off the film, the glue is apt to
remain on the polarizer.
Please carefully peel off the protection film without rubbing it against the polarizer.

(3) When the module with protection film attached is stored for a long time, sometimes there remains a

very small amount of glue still on the polarizer after the protection film is peeled off.

(4) You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is

recognized, please wipe them off with absorbent cotton waste or other soft material like chamois
soaked with normal-hexane.
