Parameter
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.
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.
