.
This phenomenon is caused by interference between lamp (CCFL) lighting frequency and
LCD horizontal synchronous signal.)
* 4. The “MAX” of “Kick-Off Voltage” means the minimum voltage for inverter to turn on the CCFL
normally in the LCD module. However this isn’t the values that we can assure stability of
starting lamp on condition that the module is installed in your set.
It should be careful that “Kick-Off Voltage” is changed by an increase of stray capacitance in
your set, inverter method, value of ballast capacitor in your inverter and so on.
Especially, the value of “Kick-Off Voltage” is higher in low temperature condition than in
normal temperature condition, because impedance of CCFL is increased.
The voltage above VS should be applied to the lamps for more than 1 second for start-up.
Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.
* 5. The time needed to achieve not less than 95%brightness of the center part of lamp.
The brightness of the lamp after being lighted for 5 minutes is defined as 100%.
* 6. “Life time” is defined as the time that the lamp brightness decreases to 50% from original
brightness
at IBL=TYP; continuous lighting, Ta=25 .
Ip
I -p
* Asymmetry rate:
( I p – I –p |) / Irms * 100%
•Distortion rate:
I p (or I –p) / Irms
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 as follows. It shall help increase the lamp
lifetime
and reduce leakage current. Inverter should be designed to be subject to the conditions below
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.
C. There should not be any spikes in the waveform.
D. Lamp current should not exceed the “MAX” value under the “Operating Temperature” (it is
prohibited to exceed the “MAX.” value even if it is operated in the guaranteed temperature).
When lamp current exceed the maximum value for a long time, it may cause a smoking and
Ignition.
Therefore, it is recommended that the inverter have the current limited circuit that is used as a
protection circuit and/or the lamp current-controlled inverter.
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.
