1. General Description

15"(Not Fixed) 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. It has a 15.0 inch 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 are arranged in vertical stripes.
Gray scale or the brightness o f the sub-pixel color is determined wi th a 8-bit gray scale signa l for each dot,
thus, presenting a palette of more than 16M colors.
It has been designed to apply the 8-bit 1 port LVDS interface.
It is intended to support applications where high brightness, super wide viewing angle, high color
saturation, and high color are important.

3-1. Electrical Characteristics

It requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and
liquid crystal. The second input power for the CCFL, is typically generated by an inverter. The inverter is an
external unit to the LCDs.

Note : The design of the inverter must have specifications for the lamp in LCD Assembly.

The performance of the Lamp in LCM, for e xample life time or brightness, is e xtremely 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) ne ver occurs. When you confirm it, the LCD–
Assembly should be operated in the same condition as installed in you instrument.

※ 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.

1. Specified values are for a single lamp.

2. Operating voltage is measured at 25 ± 2

3. The voltage above V

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

S

C. The variance of the voltage is ± 10%.

(Inverter open voltage must be more than lamp starting voltage.)

Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.

4. Lamp frequency may produce interface with horizonta l 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.

5. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
T

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

S

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

= VBLx IBLx N

7. 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 ± 2

8. 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.
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 √2 ±10%.

* Inverter output waveform had better be more similar to ideal sine wave.

* Asymmetry rate:

9. The inverter which is combined with this LCM, is highly recommended to connect coupling(ballast)
condenser at the high voltage output side. When you use the inverter which has not coupling(ballast)
condenser, it may cause abnormal lamp lighting because of biased mercury as time goes.

10.In case of edgy type back light with over 4 parallel lamps, input current and voltage wave form should
be synchronized
