LM181E1-H2MN
Liquid Crystal Display
Product Specification
1. General Description
The LM181E1-H2MN is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode
Fluorescent Lamp(CCFL) back light 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 LM181E1-H2MN 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 LM181E1-H2MN 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 LM181E1-H2MN characteristics provide an excellent flat panel display for office
automation products such as monitors.

3. Electrical Specifications
3-1. Electrical Characteristics
The LM181E1-H2MN requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The other 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, etc) never occurs. When you confirm it, the LCD Assembly
should be operated in the same condition as installed in your instrument.
Notes:1. The current draw and power consumption specified is for 12.0 Vdc at 25 and fv at 60Hz.
(at 8-gray pattern displayed)
2. The variance of the voltage is ±10%.
3. The output voltage at the transformer in the inverter must be high considering to the loss of the
ballast capacitor in the inverter.
4. 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 interference with horizontal synchronous frequency and as a result
this may cause beat on the display. Therefore lamp frequency shall be as away as possible from
the horizontal synchronous frequency and from its harmonics in order to prevent interference.
5. The lamp power consumption shown above does not include loss of external inverter.
6. 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%.
7. The life time is determined as the time at which brightness of lamp is 50% compare to that of
initial value at the typical lamp current on condition of continuous operating at 25 ±2 .

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 = 8.0 mArms. For more information see
Appendix A - 2.
3. The variation in surface Luminance, WHITE is determined by measuring LON at each test position
1 through 5, and then dividing the maximum LON of 5 points luminance by minimum LON of 5
points luminance. For more information see Appendix A - 2.
WHITE
Maximum (LON1, LON2, ....LON5) ÷ Minimum (LON1, LON2, ....LON5)
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 Appendix A - 3.

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 user 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 with a transparent protective plate in order to protect the polarizer LC cell.
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 polarizer with glass, tweezers or anything harder than HB
pencil head 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 soaked with petroleum benzene. Normal-hexane is recommended for cleaning the
adhesives used to attach front / rear polarizer. 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 malfunction 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) A module has high frequency circuit. If you need to shield the electromagnetic noise, please do
co-work together.
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 I/F pin
directly.
9.4 PRECAUTION 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 and 35 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) 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) The protection film is attached to the polarizer with a small amount of adhesive tape. If some stress
is applied to rub the protection film against the polarizer during the time you peel off the film, the
adhesive tape is apt to remain on the polarizer.
Please carefully peel off the protection film without rubbing it against the polarizer.
(3) When the module with protection film attached is stored for a long time, sometimes there remains a
very small amount of adhesive tape still on the polarizer after the protection film is peeled off.
(4) You can remove the adhesive easily. When the adhesive remains on the polarizer surface or its
vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like
chamois soaked with normal- hexane.
