1. General description

LM220WE1-TLP1 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent

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 Advanced-FRC(Frame Rate Control). It has been designed to apply the interface
method that enables low power, high speed, low EMI. FPD Link or compatible must be used as a LVDS(Low
Voltage Differential Signaling) chip. It is intended to support applications where thin thickness, wide viewing
angle, low power are critical factors and graphic displays are important. In combination with the vertical
arrangement of the sub-pixels, the LM220WE1-TLP1 characterist
office automation products such as monitors.

Note :

The design of the inverter must have specifications 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.

୔ 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 r 2¶C. The variance of the voltage is r 10%.

3. The voltage above V
(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%.

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

The used lamp current is the lamp typical current. (P

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 r 2¶C.

Note :

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.

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

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.

ome 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) 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=·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

.

(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 metal

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.

9-5. 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

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.
