1. General Description
LC230EUE is a Color Active Matrix Liquid Crystal Display with a Light Emitting Diode ( White LED) backlight
system without LED driver. 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 23 inch diagonally measured
active display area with FHD resolution (1080 vertical by 1920horizontal 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 A-FRC (Advanced Frame Rate Control).
It has been designed to apply the 8Bit 2 port LVDS interface.
It is intended to support displays where high brightness, super wide viewing angle,
high color saturation, and high color are important.

2. Maximum Storage Humidity is up to 40, 70% RH only for 4 corner light leakage Mura.
3. Storage condition is guaranteed under packing condition
4. Gravity mura can be guaranteed below 40¶C condition
5. The maximum operating temperatures is based on the test condition that the surface temperature
of display area is less than or equal to 68¶C 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. The range of operating temperature may be degraded in case of
improper thermal management in final product design.

3. Electrical Specifications
3-1. Electrical Characteristics
It requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and
liquid crystal. The second input power for the LED/Backlight, is typically generated by a LED Driver.
The LED Driver is an external unit to the LCDs.

Notes) The LED Bar consists of 34 LED packages, 2 strings (parallel) x 17 packages (serial)
LED driver design guide
: The design of the LED driver must have specifications for the LED in LCD Assembly.
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 and output current should be
Constant current control.
Please control feedback current of each string individually to compensate the current variation
among the strings of LEDs.
When you design or order the LED driver, please make sure unwanted lighting caused by
the mismatch of the LED and the LED driver (no lighting, flicker, etc) never occurs.
When you confirm it, the LCD module should be operated in the same condition as installed in
your instrument.
Unit Notes
1. The specified values are for a single LED bar.
2. The specified current is defined as the input current for a single LED string with 100% duty cycle.
3. The LED life time is defined as the time when brightness of LED packages become 50% or less
than the initial value under the conditions at Ta = 25 r 2¶C and LED string current is typical value.
4. The power consumption shown above does not include loss of external driver.
The typical power consumption is calculated as P
The maximum power consumption is calculated as P
Bar = Vs(Typ.) x Is(Typ.) x No. of strings.
Bar = Vs(Max.) x Is(Typ.) x No. of strings.
5. LED operating conditions are must not exceed Max. ratings.

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 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.
(10) As The IPS panel is sensitive & slim, please recommend the metal frame of the system supports the panel
by the double side-mount.
www.panelook.com
LC230EUE
Liquid Crystal Display
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 causes metallic foreign material and deal LCM a fatal blow)
(9) Please do not set LCD on its edge.
(10) When LCMs are used for public display defects such as Yogore, image sticking can not be guarantee.

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.
www.panelook.com
LC230EUE
Liquid Crystal Display
Product Specification
(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.
(3) Storage condition is guaranteed under packing conditions.
(4) The phase transition of Liquid Crystal in the condition of the low or high storage temperature will be
recovered when the LCD module returns to the normal condition
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.
