[Note 7] Measurement condition
(1) Measurement equipment: BM-5A (TOPCON Corp.), Field=2 degree
(2) Ambient temperature Ta: 25 +/- 2 degC
(3) LCD: All pixels are WHITE, VDD=3.3V, fV=60Hz
(4) Measure after 30 minutes of CFL w arm up.
(5) IL=6.0 mArms w ith the Lamp inverter CXA-L0612A-VJL (TDK).

[Note 1] Backlight driving conditions (operating frequency fL especially) may interfere w ith
horizontal frequency fH, causing the beat or flicker on the display.
Therefore the operating frequency fL shall be adjusted in relation to horizontal
frequency fH to avoid interference.
[Note 2] The inverter open voltage should be larger than start up voltage, otherw ise backlight
may blinking for a moment after turns on or not be turned on.
And this voltage should be applied to lamp for more than 1 second to start up,
otherw ise backlight may not be turned on.
[Note 3] If driving current w aveform is asymmetrical, mercury deviation inside of CFL w ill
incline to one side and consequently abnor mal lighting may occur.
To prevent such unfavorable lighting, driving current w aveform is asked to have
unbalance rate of less than 10% and w ave-height rate of less than 2 +/- 10%.
And this driving w aveform shall be confirmed in your system.
Unbalance rate = | Ip - I- p | / IL x 100 (%)
Ip Wave-height rate = Ip (or I-p) / IL
I-p
Current waveform
Ip : High peak value
I-p : Low peak value
IL : Effective value
[Note 4] The inverter of ground reference type should be used. The inverter of ground floating
type should not be used.

When the pow er is off, LVDS input must be kept at either low level or high impedance.
Pow er sequence for Lamp(backlight) is not specified especially, how ever it is
recommended to consider some timing difference between LVDS input as show n above.
If backlight lights on before LCD starts function, or if backlight is kept on after LCD
stopped function, screen may look w hite for a moment or abnor mal image may be
displayed.
This is caused by variation in output signal from timing generator at LVDS input on or
off. It does not cause damage to liquid crystal molecule and driving circuit.
