Liquid Crystal Display

Product Specification

1. General description

LM195WD1-TLC1 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting
Diode(LED) 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 19.5 inch
diagonally measured active display area with HD+ resolution (900 vertical by 1600 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 colors with
Advanced-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 sub-pixels, the LM195WD1-TLC1 characteristics
provide an excellent flat panel display for office automation products such as monitors.

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 LED/Backlight, is typically
generated by an LED Driver. The LED driver is an external unit to the LCDs.

Notes) The LED Bar consists of 24 LED packages, 2 strings (parallel) x 12 packages (serial)

LED driver design guide
: The design of the LED driver must have specifications for the LED in LCD Assembly.
The performance of the LED in LCM, for example life time or brightness, is extremely
influenced by the characteristics of the LED driver.
So all the parameters of an LED driver should be carefully designed and output current
should be Constant current control.
Please control feedback current of each string individually to compensate the current
variation among the strings of LEDs.
When you design or order the LED driver, please make sure unwanted lighting caused by
the mismatch of the LED and the LED driver (no lighting, flicker, etc) never occurs.
When you confirm it, the LCD module should be operated in the same condition as
installed in your instrument.

Notes :

1. The specified values are for a single LED bar.

2. The specified current is defined as the input current for a single LED string with 100% duty cycle.

3. The LED life time is defined as the time when brightness of LED packages become 50% or less
than the initial value under the conditions at Ta = 25  2°C and LED string current is typical value.

4. The power consumption shown above does not include loss of external driver.
The typical power consumption is calculated as PBar = Vs(Typ.) x Is(Typ.) x No. of strings.
The maximum power consumption is calculated as PBar = Vs(Max.) x Is(Typ.) x No. of strings.

5. LED operating conditions must not exceed Max. ratings.

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 left & right 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.

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 Higher 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
not be operated its full characteristics perfectly.
(8) A screw which is fastened up the steels should be a machine screw (if not, it causes metal
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 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.
