Liquid Crystal Display

Product Specification

1. General Description

The LM170E03-TLJ1 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 16.7M colors with A-FRC(Advanced-Frame Rate Control).

The LM170E03-TLJ1 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 LM170E03-TLJ1 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 LM170E03-TLJ1 characteristics provide an excellent flat panel display foroffice automation products such as
monitors.

3. Electrical specifications
3-1. Electrical characteristics

The LM170E03-TLJ1 requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. Another which powers theCCFL, is typically generated by an inverter.

The inverter is an external unit to the LCD.

1. The specified current and power consumption are under the V
whereas mosaic pattern(8 x 6) is displayed and fVis the frame frequency.

2. The current is specified at the maximum current pattern.

3. Permissive power ripple should be measured under V

conditionand At that time, we recommend the bandwidth configuration of oscilloscope is to be under
20MHz.

4. The duration of rush current is about 2ms and rising time ofpower Input is 500us ± 20%.(min.).

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

www.jxlcd.com

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 ± 2°C. The variance of the voltage is ± 10%.

3. 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.

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%.

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

6. 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

7. The life is determined as the time at which brightness of thelamp is 50% compared to that of initial

value at the typical lamp current on condition of continuousoperating at 25 ± 2°C.

8. The output of the inverter must have symmetrical(negative andpositive) 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.

* Asymmetry rate:

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 usethe 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

Figure 10. Luminance measuring point

1. Contrast ratio(CR) is defined mathematically as :
Surface luminance with allwhite pixels

Contrast ratio =

Surface luminance with allblack pixels

2. Surface luminance is the center point across the LCD surface 50cm from the surface with all
pixels displaying white. For more information see [ Figure 10 ].

3. The uniformity in surface luminance , △L9is determined by measuring LONat any point in test area.
But the management of △L9is determined by measuring Lon at each test position 1 through 9,
and then dividing the maximum LONof 9 points luminance by minimum L
For more information see [ Figure 10 ].

7. Luminance Uniformity -angular – dependence (LR& TB)

TCO 5.0 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.

-Test pattern : Full white 4˚× 4˚square size,

-Test luminance : ≥150cd/㎡

-Test point : 5-point

)''()''( BABA vvuu −− +

Where indices A and B are the two gray levels found to have the largest color differences

between them.
i.e. get the largest Δu’ and Δv’ of each 6pairs of u’ and v’ and calculate Δu’v’ .

a. Test pattern : 100% full white pattern with a test pattern as shown below.

Squares of 40mm by 40mm in size, filled with 255, 225, 195, 165, 135 and 105
grayscale steps should be arranged in thecenter of the screen.

b. Test method

First gray step : move a square of 255 gray level should be moved into the center of the screen

and measure luminance and u’ and v’ coordinates.

Next gray step : move a 255 gray square into the center and measure both luminance and

u’ and v’ coordinates.
The same procedure shall then be repeated for gray steps 195, 165, 135 and 105.

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 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 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 polarizerswith 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.

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

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 theBezel or its vestige is recognized,

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