1. General Description
The LP141WP1 is a Color Active Matrix Liquid Crys tal Display with an integral Cold Cathode Fluo rescent
Lamp (CCFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active e lement. It is a
transmissive type display operating in the normally white mode. This TFT-LCD has 14.1 inches diagonally
measured active display area with WXGA+ resolution(900 vertical by 1440 horizontal pixel array). Each
pixel is divided into Red, Green and Blue sub -pixels or dots which are arranged in vertical st ripes. Gray
scale or the brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot, thus,
presenting a palette of more than 262,144 colors.
The LP141WP1 has been designed to apply the interface me thod that enables low power, high speed, low
EMI.
The LP141WP1 is intended to support applications where thin thickness , low power are critica l factor s and
graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the
LP141WP1 characteristics prov ide an excellent flat display for office automa t ion products such as Notebook
PC.

3. Electrical Specifications
3-1. Electrical Characteristics
The LP141WP1 requires two power inputs. One is employed to power the LCD electronic s 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 t h e L CD.

1. The specified current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition
whereas full black pattern (Window Desk Top Pattern) is displayed and fv is the frame frequency.
2. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.
3. The typical operating current is for the typical surface luminance (L
4. Define the brightness of the lamp after being lighted for 5 minutes as 100%, Ts is the time required for
the brightness of the center of the lamp to be not less than 95%.
5. The life time is determined as the time at which brightness of lamp is 50% compare to that of initial value
at the typical lamp current.
6. The output of the inverter must have symmetrical(negative and positive) voltage waveform and
symmetrical current waveform.(Asymmetrical ratio is less than 10%) Please do not use the inverter
which has asymmetrical voltage and asymmetrical current and spike wave.
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.

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, 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%.
www.jxlcd.com
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:

※ 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.
