6-2. Back light driving
The back light system is an edge-lighting type with 6 CCFTs (Cold Cathode Fluorescent Tube).
The characteristics of the lamp are shown in the following table.
The value mentioned below is at the case of one CCFT.
Parameter Symbol Min. Typ. Max. Unit Remark
Lamp current range IL 3 6 7 mArms Note1
Lamp voltage VL 800 900 Vrms Ta=25 IL=6.0mArms FL=60kHz
Lamp power consumption PL 4.8 5.4 W Note2 IL=6.0mArms FL=60kHz
Lamp frequency FL 35 60 70 KHz Note3
Kick-off voltage Vs 1800 Vrms Ta=25 Note4
2000 Vrms Ta=0 Note4
Lamp life time TL 50,000 Hour Note5
Note1 A lamp can be light in the range of lamp current shown above.
Maximum rating for current is measured by high frequency current measurement equipment
connected to VLOW at circuit showed below.
(Note : To keep enough kick-off voltage and necessary steady voltage for CCFT.)
Lamp frequency : 35 70kHz
Ambient temperature : 0 50
Note2 Referential data per one CCFT by calculation ( IL VL ) .
The data doesn't include loss at inverter .
Note3 Lamp frequency of inverter may produce interference with horizontal synchronous frequency, and
this may cause horizontal beat on the display. Therefore, adjust lamp frequency, and keep inverter as far
as from module or use electronic shielding between inverter and module to avoid interference.
Note4 It is defined at 27pF for the ballast capacitor of a DC-AC inveter.
The Kick-off voltage may rise up in the user set,please decide the open output voltage by checking not
to occur lighting failure under operating state.
The open output voltage should be applied to the lamp for more than 1 second to startup. Or when the
ambient luminance around the lamp is more than 1lux,it should be applied to the lamp for more than
100ms.Otherwise the lamp may not be turned on..
Note5 Lamp life time is defined as the time when either or occurs in the continuous operation under
the condition of Ta=25 and IL=6.0 mArms .
Brightness becomes 50% of the original value under standard condition.
Kick-off voltage at Ta=0 exceeds maximum value,2000Vrms .
(Lamp lifetime may vary if lamp is in portrait position due to the change of mercury density inside the lamp.)
In case of operating under lower temp environment, the lamp exhaustion is accelerated and the brightness
becomes lower. (Continuous operating for around 1 month under lower temp condition may reduce the
brightness to half of the original brightness.)
In case of such usage under lower temp environment, periodical lamp exchange is recommended.

[Note6] The performance of the backlight, for example life time or brightness, is much influenced by the
characteristics of the DC-AC inverter for the lamp. When you design or order the inverter, please
make sure that a poor lighting caused by the mismatch of the backlight and the inverter
(miss-lighting, flicker, etc.) never occur. When you confirm it, the module should be operated in the
same condition as it is installed in your instrument.
Be sure to use a back light power supply with the safety protection circuit such as the detection circuit
for the excess voltage, excess current and or electric discharge waveform.
Be sure to use the detect circuit by which one side of the CCFT lamps can be controlled independently.
Otherwise, when one side of the CCFT is open, the excess current may possibly be applied to the other
side of the lamp.
[Note7] It is required to have the inverter designed so that to allow the impedance deviation of the two CCFT
lamps and the capacity deviation of barast capacitor.
[Note8] Under the environment of 10lx or less, miss-lighting or lighting delay may occur.
