1. General Description
The LP141 WX3 is a Color Active Matrix Liquid Crystal Disp lay with an integ ral Cold Cathode Fluorescent
Lamp (CCFL) backlight system. The matrix emp loys a-Si Thin Film Transis to r as the active element. It is a
transmissive type disp lay operating in the normally white mod e. This TFT-L CD has 14.1 inches diagonally
measured active d isplay area with WXGA resolution(800 vertical by 1280 horizontal p ixel arr ay). Each p ixel
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-p ixel c olor is determined with a 6-b it gray scale signal for each dot, thus,
presenting a palette of more than 262,144 c olors.
The LP141WX3 has been designed to apply the interf ace method that enables low power, hig h speed, lo w
EMI.
The LP141WX3 is intended to support applications where thin thic kness, low po wer are critical f actors and
graphic display s are important. In combination with the vertical arrangement of the sub -pixels, the
LP141 WX3 characteristics p rovide an excellent flat disp lay for office automatio n products such as Notebook
PC.

3-1. Electrical Characteristics
The LP141WX 3 req uires two power inputs. One is emp lo yed to power the LCD electronic s and to d rive the
TFT array and liquid crystal. The second input which powers the CCF L, is typically generated by an
inverter. The inverter is an external unit to the LCD.

6. The o utp ut of the inverter must have symmetrical(negative and positive) vo ltage wavef orm and
symmetrical current waveform.(Asymmetrical ratio is less than 10%) Please d o not use the inverter
which has asy mmetrical voltage and asymmetrical current and spike wave.
Lamp frequency may produce interf ace with horizo ntal synchro nous f requency and as a result this may
cause beat on the d isplay. Theref ore lamp f requency shall be as away possible from the

better p ower ef f iciency and a more reliable lamp, are f o llo wing.
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. PRECAUTIONS
Pleas e pay attention to the f ollo wings when you use this TFT LCD module.
9-1. MOUNTING PRECAUT IONS
(1) You must mount a module using holes arranged in f our corners or f our sides.
(2) You sho uld consider the mo unting structure so that uneven force (ex. Twisted stress) is not applied to
the
module. And the case o n which a mod ule 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 s urf ace in o rder to p rotect the p olarizer.
Transparent protective plate should hav e suf f ic ient streng th in ord er to the resist external f orce.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials f or the cover case are not d esirable b ecause the f ormer
generates corros ive gas of attacking the po larizer at high temperature and the latter causes circuit break
by electro-chemical reaction.
(6) Do not touch, p ush o r rub the exposed polarizers with glass, tweezers o r anything harder than HB
pencil lead . And p lease do not rub with dust clothes with chemical treatment.
Do no t touch the surface of po larizer f or b are hand o r greasy cloth.(Some cosmetics are detrimental
to the polarizer.)
(7) Whe n the surf ace becomes dusty, please wipe gently with ab sorbent cotto n or other sof t materials like
chamois so aks with p etroleum benzene. Normal-hexane is recommended for cleaning the adhesives
used to attach front / rear p olarizers. D o not use acetone, toluene and alcoho l because they cause
chemical damage to the p olarizer.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes
deformations and co lo r f ading.
(9) D o not op en the case because insid e circuits do not have suf ficient strength.
www.panelook.com
LP141WX3
Liquid Crystal Display
Product Specification
9-2. OPERATING PRECAUT IONS
(1) The spike noise causes the mis -operation of circuits. It should be lower than f ollowing voltag e :
V=· 200mV(Over and under shoot voltage)
(2) Respons e time depend s on the temperature.(In lo wer temp erature, it b eco mes longer.)
(3) Brig htness dep ends on the temperature. (In lower temperature, it bec omes lower.)
And in lower temperature, response time(required time that brightness is stable after turned on) becomes
longer.
(4) Be ca ref ul for condensation at sudd en temperature change. Condensatio n makes damag e to polarizer or
electrical contacted parts. And after fading condensation, smear or spot will occur.
(5) When fixed patterns are displayed f or a long time, remnant image is likely to occur.
(6) Mod ule has high f requency circuits. Sufficient suppression to the electromagnetic interf erence shall be
done by system manuf acturers. Grounding and shielding method s may b e impo rtant to minimized the
interference.

9-3. ELECTROSTATIC DISCHARGE CONTROL
Sinc e a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that
treatment persons are connected to g round through wrist band etc. And don’t touch interf ace pin directly.
9-4. PRECAUTIONS FOR STRONG LIGHT EXPOSURE
Strong lig ht ex posure causes degrad ation o f polarizer and color f ilter.
9-5. STORAGE
www.panelook.com
LP141WX3
Liquid Crystal Display
Product Specification
When storing modules as spares f or a lo ng time, the f ollo wing precautio ns are necess ary.
(1) Store th em in a dark place. Do not exp ose the module to sunlight o r f luorescent lig ht. Keep the
temperature between 5qC and 35qC at normal humidity.
(2) The polarizer surface sho uld not come in contact with any other ob ject.
It is recommend ed that they be s to red in the container in which they were shipp ed.
9-6. HANDLING PRECAUTIONS FOR PROTECT ION FILM
(1) When the pro tection f ilm is peeled of f , static electricity is g enerated between the f ilm and p olarizer.
This should b e peeled of f slowly and carefully b y peo ple who are electrically grounded and with well
ion-blown equipment or in s uch a conditio n, etc.
(2) The p rotection film is attached to the polarizer with a small amount of glue. If some stress is ap plied
to rub the protection film ag ainst the po larizer during the time yo u peel o f f the film, the g lue is apt to
remain o n the polarizer.
Pleas e caref ully peel of f the pro tection f ilm witho ut rubbing it ag ainst the p olarizer.
(3) When the module with protection film attached is stored f or a long time, so metimes there remains a
very small amount of glue still on the polarizer after the protection film is peeled of f .
(4) You can remove the glue easily. When the glue remains o n the po larizer surf ace or its vestig e is
reco gnized, please wipe them o f f with abs orbent cotton waste or other soft material like chamois
so aked with normal-hexane.
