1. General Description
The LC420WUE is a Color Active Matrix Liquid Crystal Display with an integral External Electrode Fluorescent
Lamp(EEFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive display type which is operating in the normally black mode. It has a 42.02 inch diagonally
measured active display area with WUXGA resolution (1080 vertical by 1920 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 1.06BilionM(true) colors.
It has been designed to apply the 10-bit 2-port LVDS interface.
,
high color depth and fast response time are important.

Note :
The design of the inverter must have specifications for the lamp in LCD Assembly.
The electrical characteristics of inverter are based on High-High Driving type.
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) has never been occurred. When you confirm it, the LCD–
Assembly should be operated in the same condition as installed in your instrument.
Ć Do not attach a conductive tape to lamp connecting wire.
If you attach conductive tape to the lamp wire, not only luminance level can be lower than typical one but
also inverter operate abnormally on account of leakage current which is generated between lamp wire and
conductive tape.
1. Specified values are defined for a Backlight Assembly.( IBL : 16 lamp, 8.5 mA/Lamp)
2. Operating voltage is measured at 25 r 2¶C(after 2hr.aging).The variance range for operating voltage
is r 10%.

3. The Striking Voltage (Open Lamp Voltage) [ Vopen ] should be applied to the lamps more than Striking
time (S
TIME) for start-up. Inverter Striking Voltage must be more than Established Starting Voltage of lamp.
Otherwise, the lamps may not be turned on. The used lamp current is typical value.
When the Striking Frequency is higher than the Operating Frequency , the parasitic capacitance
can cause inverter shut down, therefore It is recommended to check it.
4. Lamp frequency may produce interference with horizontal synchronous frequency.As a result this may
cause beat on the display. Therefore, lamp frequency shall be away as much as possible from the
horizontal synchronous frequency and its harmonics range in order to prevent interference.
5. The brightness of the lamp after lighted for 5minutes is defined as 100%.

The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn on.
6. Maximum level of power consumption is measured at initial turn on.

.
7. The life time 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, based on duty 100%.
8.The output of the inverter must have symmetrical(negative and positive) voltage and current waveform
(Unsymmetrical ratio is less than 10%). Please do not use the inverter which has not only unsymmetrical
voltage and current but also spike wave.

Note : 1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Surface Luminance with all black pixels
It is measured at center 1-point.
2. Surface luminance are determined after the unit has been ‘ON’ and 1 Hour after lighting the
backlight in a dark environment at 25·2¶C. Surface luminance is the luminance value at center
1-point across the LCD surface 50cm from the surface with all pixels displaying white.
For more information see the FIG. 2.
3. The variation in surface luminance , G WHITE is defined as :

For more information, see the FIG. 2.
4. Response time is the time required for the display to transit from G(N) to G(M) (Rise Time, Tr
and from G(M) to G(N) (Decay Time, Tr
Ć G to G Spec stands for average value of all measured points.

5. Gray to Gray Response time uniformity is Reference data.
6. 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 module surface. For more information, see the FIG. 4.

Please do not set LCD on its edge
9. Precautions
ease pay attention to the followings when you use
9-1. Mounting Precautions
(1) You must mount a module using specified mounting holes (Details refer to the drawings).
(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.
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
e polarizer.
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like
chamois soaks with petroleum benzine. 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 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’t be operated
its full characteristics perfectly.
(8) A screw which is fastened up the steels should be a machine screw.
(if not, it can causes conductive particles and deal LCM a fatal blow)
(10) The conductive material and signal cables are kept away from transformers to prevent abnormal display,
sound noise and temperature rising.
(11) Partial darkness may happen during 3~5 minutes when LCM is operated initially in condition that
luminance is under 40% at low temperature (under 5). This phenomenon which disappears naturally
after 3~5 minutes is not a problem about reliability but LCD characteristic.

(12) Partial darkness may happen under the long-term operation of any dimming without power on/off.
This phenomenon which disappears naturally after 5 minutes is not a problem about reliability but
LCD characteristics.
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
www.panelook.com
LC420WUE
Product Specification
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
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 ionblown 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 normalhexane.
