Liquid Crystal Display
Product Specification
1. General Description
The LM181E06-A4M1 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. This TFT-LCD has a 18.1 inch diagonally
measured active display area with SXGA resolution(1024 vertical by 1280 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 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 16,777,216 colors.
The LM181E06-A4M1 has been designed to apply the interface method that enables low power, high speed,low
EMI. FPD Link must be used as a LVDS(Low Voltage Differential Signaling) chip.
The LM181E06-A4M1 is intended to support applications where thin thickness, wide viewing angle, low power are
critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-pixels,
the LM181E06-A4M1 characteristics provide an excellent flat panel display for office automation products such as
monitors.

3. Electrical Specifications
3-1. Electrical Characteristics
The LM181E06-A4M1 requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated
by an inverter. The inverter is an external unit to the LCD.

Note : The design of the inverter must have specifications for the lamp in LCD Assembly.
The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by
the characteristics of the DC-AC inverter. So all the parameters of an inverter should be carefully
designed so as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch
of the lamp and the inverter(no lighting, flicker, et c) never occurs. When you confirm it,
the LCD Assembly should be operated in the same condition as installed in you instrument.
Requirements for a system inverter design, which is intended to have a better display performance,
a better power efficiency and a more reliable lamp.
It shall help increase the lamp lifetime and reduce its leakage current.
a. The asymmetry rate of the inverter waveform should be 10% below;
b. The distortion rate of the waveform should be within v2 ±10%;
c. The ideal sine wave form shall be symmetric in positive and negative polarities.

1. The specified current and power consumption are under the VCC=12.0V, 25°C, f V=60Hz condition,
Typical supply current is measured at the condition of 8 X 6 chess pattern(white & black)
2. This impedance value is for impedance matching between LVDS TX and
the mating connector of the LCD.
3. The duration of rush current is about 1ms.
4. The variance of the voltage is ± 10%.
5. The voltage above VBS should be applied to the lamps for more than 1 second for start-up.
Otherwise, the lamps may not be turned on.
6. The output of the inverter must have symmetrical (negative and positive) voltage waveform and
symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter
which has unsymmetrical voltage and unsymmetrical current and spike wave.
Lamp frequency may produce interface with horizontal synchronous frequency and as a result this
may cause beat on the display. Therefore lamp frequency shall be as away possible from the
horizontal synchronous frequency and from its harmonics in order to prevent interference.
7. Let ’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
TS is the time required for the brightness of the center of the lamp to be not less than 95%.
The used lamp current is the lamp typical current.
8. The lamp power consumption shown above does not includeloss of external inverter.
The used lamp current is the lamp typical current.
9. The life time is determined as the time at which brightness 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.
Typical life time shall be defined that remained rate maintains over 50% of total amount at the life test.
? Do not attach a conductive tape to lamp connecting wire.
If the lamp wire attach to a conducting tape, TFT-LCD Module has a low luminance and the inverter has
abnormal action. Because leakage current is occurred between lamp wire and conducting tape.

Notes : 1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
2. Surface luminance is the center point across the LCD surface 50cm from the surface with all
pixels displaying white under the condition of IBL = 7mArms . For more information see FIG 2.
3. The variation in surface luminance , δ WHITE is determined by measuring LON at each test
position 1 through 9, and then dividing the maximum LON of 9 points luminance by minimum LON
of 9 points luminance. For more information see FIG 2.
δ WHITE = Maximum(LON1,LON2, ….. LON9) ÷ Minimum(LON1,LON2, ….. LON9)
4. TCO’99 Certification Requirements and test methods for environmental labeling of
display [ flat ] Report No.2 (×1.5.2. Luminance Uniformity)
LR = (LMAX.+ 30deg. / LMIN. + 30deg. ) + (LMAX.- 30deg. / LMIN. - 30deg. ) ) / 2
5. 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.
6. 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.
7. Cross talk shall be measured at the V and H position.(Window size : 427×341pixels)
For more information see FIG. 5.

9. PRECAUTIONS
Please pay attention to the followings when you use this TFT LCDmodule.
9-1. MOUNTING PRECAUTIONS
(1) You must mount a module using holes arranged in four corners.
(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 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.
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.

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
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.
