Product Specification

1. General Description

The LC420WX5 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 black mode. It has a 42.0 inch diagonally measured
act i ve dis p lay ar ea wi th WXG A re sol uti on (7 68 ve rti cal b y 1366 hor izo nta l pix el ar ray).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the luminance 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(true) colors.
It has been designed to apply the 8-bit 1-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.

1. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 120
minutes at 25±2°C. The specified current and power consumption are under the typical supply Input voltage
24V and Vbr 1.65V, it is total power consumption.
The ripple voltage of the power supply input voltage is under 0.4 Vp-p. LPL recommend Input Voltage is

24.0V ±5%.

2. Electrical characteristics are determined within 30 minutes at 25±2°C.
The specified currents are under the typical supply Input voltage 24V.

synchronized with the treble harmonic of Vsync signal of system.

5. The brightness of the lamp after lighted for 5minutes is defined as 100%.
TSis the time required for the brightness of the center of the lamp to be not less than 95% at typical current.

The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn on.

6. Specified Values are for a single lamp which is aligned horizontally.
The life time is determined as the time which luminance of the lamp is 50% compared to that of initial value
at the typical/ maximum lamp current on condition of continuous operating at 25 ± 2°C

7.The duration of rush current is about 15ms.

Note:

1. The pin no 9 is an option pin for DISM or LG format.( LG Format = “GND”or“OPEN”/ DISM Format =“VCC”)
Please refer to page 9 ,10 and 30 for further details.

2. The pin no 10 is an option pin for DCR Function ( Enable = “VCC” / Disable =“GND”)

3. The pin no 30 is LCD Test option.
“AGP” (Auto Generation LCM operates Pattern) or “NSB” (No Signal Black) is case that LVDS signals
are out of frequency or abnormal condition in spite of 12 volt power supply.
LPL recommends “NSB”. ( AGP : “VCC” or “OPEN” / NSB : “GND” )

4. All GND (ground) pins should be connected together, which should be also connected to the LCD
module’s metal frame.

5. All V

LCD

(power input) pins should be connected together.

6. Input Levels of LVDS signals are based on the IEA 664 Standard.

The brightness of each primary color(red,green,blue) is based on the 8-bit gray scale data input for the color.
The higher binary input, the brighter the color. Table 9 provides a reference for color versus data input.

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

Contrast Ratio =

Surface Luminance with all white pixels
Surface Luminance with all black pixels

It is measured at center 1-point.

2. 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 , δ WHITE and δ BLACK are defined as :

δ WHITE(5P) = Maximum(L
δ BLACK(5P) = Maximum(L

Where L

and from G(M) to G(N) (Decay Time, TrD). For additional information see the FIG. 3. (N<M)

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 module surface. For more information, see the FIG. 4.

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 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 causes metallic foreign material and deal LCM a fatal blow)
(9) Please do not set LCD module 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 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.
