1. General Description
The LC420EUS is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED) 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 42.02 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 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. Therefore, it can present a palette of more than 16.7M(true) colors. 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.

4. The maximum operating temperature is based on the test condition that the surface temperature
of display area is less than or equal to 68 ć with LCD module alone in a temperature controlled chamber. Thermal management should be considered in final product design to prevent the surface
temperature of display area from being over 68 ć. The range of operating temperature may
degrade in case of improper thermal management in final product design.

Notes :
The design of the LED driver must have specifications for the LED array in LCD Assembly. The electrical characteristics of LED driver are based on Constant Current driving type. The performance of the LED in LCM, for example life time or brightness, is extremely influenced by the characteristics of the LED Driver. So, all the parameters of an LED driver should be carefully designed. When you design or order the LED driver, please make sure unwanted lighting caused by the mismatch of the LED and the driver (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.

1. Electrical characteristics are based on LED Array specification.
2. Specified values are defined for a Backlight Assembly. (IBL : 4 LED array, 165mA/LED array)
3. Each LED array has one anode terminal and three cathode terminals. The forward current(I
) of the anode terminal is 165mA and it supplies 55mA into three strings, respectively

6. Maximum level of power consumption is measured at initial turn on.
Typical level of power consumption is measured after 1hrs aging at 25 2¶C.
7. The life time(MTTF) is determined as the time at which brightness of the LED is 50% compared to that of
initial value at the typical LED current on condition of continuous operating at 25 2C, based on duty 100%.
8. The reference method of burst dimming duty ratio. It is recommended to use synchronous V-sync frequency to prevent waterfall (Vsync x 1 =Burst Frequency)

Note :
1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance at all white pixels
CR =
Surface Luminance at all black pixels
It is measured at center 1-point.
2. Surface luminance is determined after the unit has been ‘ON’ and 1Hour 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. 10.
3. The variation in surface luminance , WHITE is defined as : 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.
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 LED driver inductor to prevent abnormal
display, sound noise and temperature rising.

(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
Strong light exposure causes degradation of polarizer and color filter.

LC420EUS
Product Specification
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 5C and 35C 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.
