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. Electrical Specifications
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.

1. The sp ecified current and power consump tion are under the Vcc = 3.3V , 25к, fv = 60Hz condition
whereas Mos aic pattern is d isplayed and fv is the f rame f requency.
2. This impedance value is needed to proper display and measured f orm LVD S Tx to the mating connector.
3. The typical o perating current is for the typical surf ace luminance (LWH) in optical characteristics.
4. Define the brightness of the lamp af ter being lighted f or 5 minutes as 100%, Ts is the time req uired f o r
the brightness of the center of the lamp to be not less than 95%.
5. The lif e time is determined as the time at which brig htnes s o f lamp is 50% compare to that of initial value
at the typ ical lamp current.

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
horizontal sync hronous frequency and from its harmonics in ord er to prevent interference.

8. The lamp po wer co nsumption shown abo ve does no t includ e loss of external inverter.
The app lied lamp current is a typical o ne.
9. Requirements for a system inverter design, which is intended to have a better display performance, a
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.

10. Inverter op en voltage must be more than lamp vo ltage f or more than 1 second f or start -up.
Otherwis e, the lamps may not be turned on.
ϡ Do no t 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 ac tion. Because leakage current is occurred between lamp wire and co nducting tape.
