Product Specification

1. General Description

The LM170E01-A5NJ 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. This TFT-LCD has a 17.0 inch diagonal
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 16.2M colors with FRC(Frame Rate Control).

The LM170E01-A5NJ 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.
The LM170E01-A5NJ 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 LM170E01-A5NJ characteristics provide an excellent flat panel display for office automation products such as
monitors.

3. Electrical specifications

3-1. Electrical characteristics

The LM170E01-A5NJ requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. Another 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.

Note. Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to conducting tape,

TFT-LCD Module have a low luminance and the inverter has abnormal action because leakage current
occurs between lamp wire and conducting tape.

1. The specified current and power consumption are under the V

=5.0V, 25¶C, fV(frame frequency)

CC

=60Hz condition. Mosaic(black & white) pattern shown in the [ Figure 3 ] is displayed.

2. The duration of rush current is about 5ms. And V

rise time is 500us r 20%.

CC

3. Operating voltage is measured under 25ఁ.The variance of the voltage is ᇹ10%.

4. The voltage above V

should be applied to the lamps for more than 1 second for start-up.

BS

Otherwise,the lamps may not be turned on.

,

5. 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.

6. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.

is the time required for the brightness of the center of the lamp to be not less than 95%.

T

s

The used lamp current is the lamp typical current.

7. The lamp power consumption shown above does not include loss of external inverter under 25ఁ.
The used lamp current is the lamp typical current.

8. The life time is determined as the time at which brightness of lamp is 50% compared to that of initial
value at the typical lamp current on condition of continuous operating at 25 ᇹ2ఁ.

9. 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 unbalance rate of the inverter waveform should be 10% below;
b. The distortion rate of the waveform should be within √2±10%;
c. The ideal sine wave form shall be symmetric in positive and negative polarities.

10. Inverter open voltage must be more than lamp starting voltage.

11. 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.

9. Precautions

Please pay attention to the following 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 a 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 describe 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 determined

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.

LM170E01

Liquid Crystal Display

Product Specification

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.
(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)

9-3. 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

Product Specification

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 or its vestige is recognized,

please wipe them off with absorbent cotton waste or other soft material like chamois soaked with
normal-hexane.
