6-2. Back light driving
The back light system is an edge-lighting type with four 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.

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 : 50 70kHz
Ambient temperature : 0 50
Note2 Referential data per one CCFT by calculation ( IL VL ) .
The data don’t include loss at inverter.
Note3 Lamp frequency may produce interference with horizontal synchronous frequency, and this may
cause beat on the display. Therefore lamp frequency shall be detached as much as possible from the
horizontal synchronous frequency and from the harmonics of horizontal synchronous to avoid
interference.
Note4 The voltage above this value should be applied to the lamp for more than 1 second to startup.
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=6.5 mArms.
Brightness becomes 50% of the original value under standard condition.
Kick-off voltage at Ta=0 exceeds maximum value, 1600 Vrms.
Note The performance of the back light, 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 back light and the inverter (miss-lighting, flicker, etc.) never occurs.
When you confirm it, the module should be operated in the same condition as it is installed in your instrument.
