1. General Description

The LC420WUN 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 1.06Bilion (true) colors.
It has been designed to apply the 10-bit 2-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

Note : 1. Contrast Ratio(CR) is defined mathematically as :

www.panelook.com

LC420WUN

Product Specification

Contrast Ratio =

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 :

G WHITE(5P) = Maximum(L

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 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.

(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 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.

www.panelook.com

LC420WUN

Product Specification

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)
(9) Please do not set LCD on its edge.
(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.

Ver. 1.0

27 /41

One step solution for LCD / PDP / OLED panel application: Datasheet, inventory and accessory!

www.panelook.com

Global LCD Panel Exchange Center

(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

LC420WUN

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

(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 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.
