6-2. Backlight driving
The backlight system is an edge-lighting type with single CCFT (Cold Cathode
Fluorescent Tube).

[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 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.
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.
