Liquid Crystal Display
Product Specification
1. General Description
LM190E03-A4 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 white mode. It has a 19.0 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, a palette of more than 16,2M
colors with FRC(Frame Rate Control). It has been designed to apply the interface method that enables low
power, high speed, low EMI. FPD Link or compatible must be used as a LVDS(Low Voltage Differential
Signaling) chip. It 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 subpixels, the LM190E03-A4 characteristics provide an excellent flat panel display for office automation products
such as monitors.

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/Backlight, 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 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 you instrument.
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. Specified values are for a single lamp.
2. Operating voltage is measured at 25 r 2¶C. The variance of the voltage is r 10%.
3. The voltage above V
(Inverter open voltage must be more than lamp starting voltage.)
Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.
4. 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.
5. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
T
is the time required for the brightness of the center of the lamp to be not less than 95%.
S
6. The lamp power consumption shown above does not include loss of external inverter.
The used lamp current is the lamp typical current. (P
7. The life 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 r 2¶C.

8. 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. 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 leakage current.
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.

9. 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 because
of biased mercury as time goes.
10.In case of edgy type back light with over 4 parallel lamps, input current and voltage
wave form should be synchronized

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 protect
the polarizer. Transparent protective plate should have sufficient strength in order to the
resist external force.
(4) You should adopt radiation structure to
(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
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 detrimen
(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 po

its 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 t
turned on) becomes longer.
(4) Be careful for condensation at sudden tem

occur.
(5) When fixed patterns are displayed for a long time, remnan

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 th
its vestige is recognized, please wipe them off with absorbent cotton waste or
other soft material like chamois soaked
e glue remains on the bezel surface or
with normal-hexane.
