Note1: When IL and/or VS are lower than Min. value, lamps will not turn on.
Note2: Recommended value of 'Ft'
Note3: The lamp current should be measured by high-frequency current meter at the low voltage terminal.
Note4: The inverter power supply has a big influence on lighting-up characteristics and the lifetime of the
Note1: LVDS signals should be measured at the terminal of 100Ω resistor.
Note2: When turn on the LCD module, if VCC voltage falls down during the rising period up to 11.4V,
Note3: The backlight should be turned ON/OFF when LVDS signals are coming. Otherwise, unstable data
This LCD module uses fuse shown below.

may be displayed when the backlight power is turned ON/OFF.
VDD
If Ft is not the recommended value, Beat noise may appear on the screen, because of interference
between Ft frequency and Hsync frequency.
Two lamps contain in the one lamp holder, and both lamps are connected to one low voltage
cable. Therefore, the lamp current at low voltage terminal is sum of two lamps (12mA Typ.)
1) 'Ft' should be within the specification.
2) Ft = 1/ 4th × (2n-1)
the power capacity of your system is less than above request, check and evaluate it carefully.
