Liquid Crystal Display
Product Specification
1. General Description
LC230WX3-SLA1 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(UCCFL) 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 23 inch diagonally measured
acti ve d ispl a y area wi th WXGA reso lution (768 vertical by 1366 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,
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.

Notes :
1. The specified current and power consumption are under the typical supply Input voltage, 24.0V.
The ripple voltage of the power supply input voltage is under 0.5 Vp-p.
Inrush current of the power supply input current is under +10% of the typical current
2. Specified values are for a single lamp which is aligned horizontally.
The life is determined as the time at which luminance of the lamp is 50% compared to that of initial
value at the typical lamp current on condition of continuous operating at 25 ± 2°C.
Specified value is when lamp is aligned horizontally.
3. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately
2Hrs in a dark environment at 25 °C± 2°C.
4. Burst mode is controlled by TV system.
5. Rush current is determined at turning on after the unit has been ‘OFF’ for 2Hrs at 25 °C± 2°C.
6. Synchronize PWM by triple with Vsync signal of system.

Note: 1. If the pin no. 9 is Ground, Interface format is “LG”, and if the pin no. 9 is Vcc(3.3V), Interface format
is “DISM”. See page 9 and 10.
2. If pin30 is 3.3V, no-signal is AGP pattern, and if pin30 is ground, no-signal is Black pattern
3. All GND (ground) pins should be connected together, which should be also connected to the LCD
module’s metal frame.
4. All VLCD (power input) pins should be connected together.
5. Input Levels of LVDS signals are based on the IEA 664 Standard.

1. Please avoid floating state of interface signal at invalid period.
2. When the interface signal is invalid, be sure to pull down the power supply VLCD to 0V.
3. The case when the T2/T5 exceed maximum specification, it operates protection
pattern(Black pattern) till valid signal inputted. There is no reliability problem.
4. The T3/T4 is recommended value, the case when failed to meet a minimum specification,
abnormal display would be shown. There is no reliability problem.

Notes 1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
It is measured at the center point(1).
2. Surface luminance is luminance value at the center point across the LCD surface 50cm from the
surface with all pixels displaying white.
For more information, see FIG 2.
3. The variation in surface luminance , δ WHITE is defined as :
δ WHITE(5P) = Maximum(Lon1,Lon2, Lon3, ...... , Lon5) / Minimum(Lon1,Lon2, Lon3, ..... , Lon5)
Where Lon1 to Lon5 are the luminance with all pixels displaying white at 5 locations .
For more information, see FIG 2.
4. Response time is the time required for the display to transition from black to white (Rise Time, TrR)
and from white to black (Decay Time, TrD).
For additional information, see FIG 3.
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 surface. For more information, see FIG 4.
6. Gray scale specification
Gamma Value is approximately 2.2.

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 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.
