LP141XB
Liquid Crystal Display
1. General Description
The LP141XB is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) back light system. The m atrix employs a-Si Thin Film Transistor as the active elem ent. It is a
transmissive type display operating in the normally white mode. This TFT-LCD has a 14.1 inc hes diagonally
measured active display area with XGA resolution(768 vertical by 1024 horizontal pixel array). Each pixel is
divided into Red, Green and Blue sub-pixels or dots which ar e arranged in vertical str ipes. Gray scale or the
brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot, thus, pres enting a
palette of more than 262,144 colors.
The LP141XB has been designed to apply the interface method that enables low power, high speed, low EMI.
Flat Link must be used as a LVDS(Low Voltage Differential Signaling) chip.
The LP141XB is intended to support applications where thin thickness, low power are critical factors and
graphic displays are important. In com bination with the vertical arrangement of the sub-pix els, the LP141XB
characteristics provide an excellent flat panel display for office automation products such as Notebook PC.

3. Electrical Specifications
3-1. Electrical Characteristics
The LP141XB requires two power inputs. One is employed to power the LCD electronics and to drive the
TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter.
The inverter is an external unit to the LCD.

Life Time
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.
Notes: 1. The specified current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition
whereas full black pattern is displayed and fv is the frame frequency.
2. This impedance value is needed to proper display and measured from LVDS Tx to the mating
connector.
3. The specified rush current and duration of rush current are under the Vcc = 3.3V,
Current limit = 1.6A, 25℃, fv = 60Hz condition whereas full black pattern is displayed and fv is the
frame frequency. The duration of rush current is about 20ms.
4. The variance of the voltage is ±10%.
5. The voltage above V
6. 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.

8. The lamp power consumption shown above does not include loss of external inverter. The used
lamp current is the lamp typical current.
9. The life 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 ±2℃.
10. Do not attach a conducting tape to lamp connecting wire. If conducting tape is attached to lamp wire,
TFT-LCD Module can have low luminance and the inverter can have abnormal action because of
leakage current.
is the time required for the brightness of the center of the lamp to be not less than 95%.

Notes 1. Contrast Ratio (CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
2. Surface luminance is the average luminance of 5points across the LCD surface 50cm from
the surface with all pixels displaying white. For more information see Appendix A - 2.
When I
=6mA, LWH= 130cd/m2 (Min.) 160cd/m2 (Typ.)
BL
3. The variation in surface luminance, δWHITE is determined by measuring L
position 1 through 9, and then dividing the maximum L
of 9 points luminance. For more information see Appendix A - 2.
δWHITE ＝ Maximum (L

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 a transparent protective plate to the surface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to 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 polalizer 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 soaked 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, 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
minimize the interference.

9.3 ELECTROSTATIC DISCHARGE CONTROL
Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Mak e 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℃ and 35℃ 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) 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) The protection film is attached to the polarizer with a small amount of glue. If some stress is applied
to rub the protection film against the polarizer during the time you peel off the film, the glue is apt to
remain on the polarizer.
Please carefully peel off the protection film without rubbing it against the polarizer.
(3) 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 polarizer after the protection film is peeled off.
(4) You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is
recognized, please wipe them off with absorbent cotton waste or other soft material like chamois
soaked with normal-hexane.
