4.3.2 Backlight lamp
Note1: This product consists of 4 backlight lamps, and these specifications are for each lamp.
Note2: The lamp voltage cycle between lamps should be kept on a same phase. "VS" and "VBLH"
Note3: The asymmetric ratio of working waveform for lamps (Power supply voltage peak ratio,
Note4: This product's backlight consists of 2 lamp holders, and each lamp holder contains 2 lamps. 2
Note5: The inverter should be designed so that the lamp starting voltage can be maintained for more
Note6: In case "FO" is not the recommended value, beat noise may display on the screen, because of

are the voltage value between low voltage side (Cold) and high voltage side (Hot).
power supply current peak ratio and waveform space ratio) should be less than 5 % (See the
following figure.). If the waveform is asymmetric, DC (Direct current) element apply into the
lamp. In this case, a lamp lifetime may be shortened, because a distribution of a lamp
enclosure substance inclines toward one side between low voltage terminal (Cold terminal)
and high voltage terminal (Hot terminal). When designing the inverter, evaluate asymmetric of
lamp working waveform sufficiently.
lamps are contained in the 1 lamp holder, and both lamps are connected to 1 low voltage cable.
Lamp current must be 5.0mArms typical for each lamp, and sum of 2 lamps must be
10mArms typical. (with whole product: 20.0mArms) The lamp current should be measured by
high-frequency current meter at the low voltage terminal.
than 1 second. Otherwise the lamp may not be turned on.
interference between "FO" and "1/th". Recommended value of "FO" is as following.
Pa: Supply voltage/current peak for positive, Pb: Supply voltage/current peak for negative
Sa: Waveform space for positive part, Sb: Waveform space for negative part.
