6-2. Backlight driving
The backlight system is an edge-lighting type with single CCFT (Cold Cathode
Fluorescent Tube).
The characteristics of the lamp are shown in the following table.

[Note2]Calculated Value for reference ( IL × V L)
[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
start-up. Otherwise the lamp may not be turned on.
[Note5] Lamp life time is defined as the time when either ① or ② occurs in the continuous
operation under the condition of Ta = 25℃ and IL = 6.0 mArms.
① Brightness becomes 50 % of the original value under standard condition.
② Kick-off voltage at Ta = 0℃ exceeds maximum value.
[Note] 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.
