Product Specification

1. General Description

LM220WE1 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 transmissive type display operating in the normally White mode. It has a 22 inch diagonally measured

active display area with WSXGA+ resolution (1050 vertical by 1680 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 8-bit gray scale signal for each dot,
thus, presenting a palette of more than 16,7M colors with A-FRC(Advanced Frame Rate Control).
It has been designed to apply the 8Bit 2 port LVDS interface.

It is intended to support displays where high brightness, super wide viewing angle,

high color saturation, and high color are important.

3-1. Electrical Characteristics

It requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and
liquid crystal. The second input power for the CCFL, is typically generated by an inverter. The inverter is an
external unit to the LCDs.

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.
※ 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.

1. Specified values are for a single lamp.

2. Operating voltage is measured at 25  2°C. The variance of the voltage is  10%.

3. The voltage above VS should be applied to the lamps for more than 1 second for start-up.
(Inverter open voltage must be more than lamp starting voltage.)
Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical
current.

4. 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.

5. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
TS is the time required for the brightness of the center of the lamp to be not less than 95%.

6. The lamp power consumption shown above does not include loss of external inverter.
The used lamp current is the lamp typical current. (PBL = VBL x IBL x N

Lamp

)

7. 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  2°C.

8. 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.
Requirements for a system inverter design, which is intended to have a better display performance, a
better power efficiency and a more reliable lamp, are following.
It shall help increase the lamp lifetime and reduce leakage current.
a. The asymmetry rate of the inverter waveform should be less than 10%.
b. The distortion rate of the waveform should be within √2 ±10%.
* Inverter output waveform had better be more similar to ideal sine wave.

* Asymmetry rate:

I p

| I p – I –p | / I

x 100%

rms

I -p

* Distortion rate
I p (or I –p) / I

rms

9. The inverter which is combined with this LCM, is highly recommended to connect coupling(ballast)
condenser at the high voltage output side. When you use the inverter which has not coupling(ballast)
condenser, it may cause abnormal lamp lighting because of biased mercury as time goes.

10.In case of edgy type back light with over 4 parallel lamps, input current and voltage wave form should
be synchronized

Notes :

1. Contrast ratio(CR) is defined mathematically as :
Surface luminance with all white pixels
Contrast ratio =
Surface luminance with all black pixels

2. Surface luminance is the center point across the LCD surface 50cm from the surface with all
pixels displaying white. For more information see [ Figure 4 ].
When IBL=7.5mA, LWH=250cd/m2(Min.) 300cd/m2(Typ.)

3. The uniformity in surface luminance , △L9 is determined by measuring LON at any point in test area.
But the management of △L9 is determined by measuring Lon at each test position 1 through 9,

and then dividing the maximum LON of 9 points luminance by minimum L

of 9 points luminance.

ON

For more information see [ Figure 4 ].
△L9= Minimum (L

ON1,LON2

, ….. L

)  Maximum (L

ON9

ON1,LON2

, ….. L

) ×100 (%)

ON9

4. Response time is the time required for the display to transition from white to black(Rise Time, TrR)
and from black to white(Decay Time, TrD). For additional information see [ Figure 5 ].
The sampling rate is 2,500 sample/sec.

5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are
determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which
is normal to the LCD surface. For more information see Figure 6 .

9. PRECAUTIONS

Please pay attention to the followings 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 the surface 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 desirable 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 detrimental

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.

9-2. OPERATING PRECAUTIONS

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

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

V=±200mV(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.
(7) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM can not be
operated its full characteristics perfectly.
(8) A screw which is fastened up the steels should be a machine screw (if not, it causes metallic foreign
material and deal LCM a fatal blow)
(9) Please do not set LCD on its edge.

9-3. ELECTROSTATIC DISCHARGE CONTROL

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.

9-4. PRECAUTIONS FOR STRONG LIGHT EXPOSURE

Strong light exposure causes degradation of polarizer and color filter.

9-5. STORAGE

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.

9-6. HANDLING PRECAUTIONS FOR PROTECTION FILM

(1) The protection film is attached to the bezel with a small masking tape.
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) 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 bezel after the protection film is peeled off.
(3) You can remove the glue easily. When the glue remains on the bezel surface or its vestige is
recognized, please wipe them off with absorbent cotton waste or other soft material like chamois
soaked with normal-hexane.
