Product Specification
1. General Description
LM215WF1 is a Color Active Matrix Liquid Crystal Display with anintegral 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 white mode. It has a 21.5inch diagonally
measured active display area with Full HD 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 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(True) colors.
Ithas 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.

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 CCFL, is typically generated by an inverter. The inverter is an
external unit to the LCDs.

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 fromhigh-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 you instrument.

Note. Do not attach a conducting 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.
1. The specified current and power consumption are under theV
whereas mosaic pattern(8 x 6) is displayed and fVis the frame frequency.
2. The current is specified at the maximum current pattern.
3. The duration of rush current is about 5ms and rising timeof power Input is 500us ± 20%.(min.).
4. Specified values are for a single lamp.
5. Operating voltage is measured at 25 ± 2°C, and follows as below condition.
The variance of the voltage is ± 10%. (Based on single Lamp.)
The variance of the voltage is ± 20%. (Based on system & Test equipment tolerance.)
6. The voltage above VSshould be applied to the lamps for more than 1 second for start-up.
(Inverter open voltage must be more than lamp startingvoltage.)
Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.
7. The output of the inverter must have symmetrical(negativeand 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.
8. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
TSis 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.
9. The lamp power consumption shown above does not include loss of external inverter.
The used lamp current is the lamp typical current. (PBL= VBLx IBLx N
10. The life is determined as the time at which brightness of the lamp is 50% compared to that of initial
www.jxlcd.com
value at the typical lamp current on condition of continuous operating at 25 ± 2°C.
11. Requirements for a system inverter design, which is intended to have a better display performance,
a better power efficiency and a more reliable lamp, are following.
It shall help increase the lamp lifetime and reduce leakagecurrent.
www.jxlcd.com
a. The asymmetry rate of the inverter waveform should be less than 10%.
b. The distortion rate of the waveform should be within √2 ±10%.
* Inverter output waveform had better be more similar to ideal sine wave.

12. The inverter which is combined with this LCM, is highly recommended to connect coupling(ballast)
condenser at the high voltage output side. When you use the inverter which has not coupling(ballast)
condenser, it may cause abnormal lamp lighting becauseof biased mercury as time goes.
13. Permissive power ripple should be measured under V
conditionand At that time, we recommend the bandwidth configuration of oscilloscope is to be under
20Mhz. See the figure 3.
14. In case of edgy type back light with over 4 parallel lamps, input current and voltage wave form should
be synchronized

Luminance Uniformity -angular – dependence (LR& TB)
TCO ‘03 Luminance uniformity – angular dependence, is the capacity of the VDU
to present the same Luminance level independently of the viewingdirection.
The angular-dependent luminance uniformity is calculated as the ratio of maximum
luminance to minimum luminance in the specified measurement areas.

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 cornersor 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.
www.jxlcd.com
www.jxlcd.com
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, smearor 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 afatal 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 thebezel surface or its vestige is recognized,
please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normalhexane.
