1. General Description

The LP154WE2 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 15.4 inches
diagonally measured active display area with WSXGA+ resolution(1680 vertical by 1050 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 6-bit gray scale signal for each dot,
thus, presenting a palette of more than 262,144 colors.

The LP154WE2 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 LP154WE2 is intended to support applications where thin thickness, low power are critical factors
and graphic display are important. In combination with the vertical arrangement of the sub-pixels, the
LP154WE2 characteristics provide an excellent flat display for office automation products such as
Notebook PC.

3. Electrical Specifications

3-1. Electrical Characteristics

The LP154WE2 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.

Note : The design of the inverter must have specification 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 you instrument.

1. The specified current and power consumption are under the V

=3.3V, 25¶C,fv=60Hz condition

CC

whereas Mosaic pattern is displayed and fv is the frame frequency.

2. This impedance value is needed to proper display and measured from LVDS T

to the mating connector.

X

3. The variance of the voltage is r 10%.

4. The voltage above V

should be applied to the lamps for more than 1 second for start-up.

S

Otherwise, the lamps may not be turned on.

5. 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.

6. It is defined the brightness of the lamp after being lighted for 5 minutes as 100%.

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

T

S

7. The lamp power consumption shown above does not include loss of external inverter.
The used lamp current is the lamp typical current.

8. The life is determined as the time at which brightness of the lamp is 50% compared to that of initial
value at the typical lamp current on condition of continuous operating at 25 r 2¶C.

9. 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.

10. 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 Ĝ2 f10%.
* Inverter output waveform had better be more similar to ideal sine wave.
