Definition of optical data, see page XXX
fFRAME=75Hz, VDD-V0=15.8V, Ta=25°C
Recommended LCD driving may fluctuate about +/- 1.0V by each module.
Flicker or ripples may occur if the LCD is operated at higher or lower
frame frequencies.

Note 5:
Background colour of the LCD changes depending on temperature.
Between 40-50°C optical characteristics of the LCD like contrast and
viewing angle change but the LCD remains readable.
Note 6:
Operating voltage is increased when CFL is operated at 0°C. Lifetime of
CFL is reduced at 0°C.
Note 7:
Storage at -20°C < 48 hrs at 60°C < 168 hrs
Note 8:
Measurement after 10 minutes of CFL operating. Brightness control 100%
Note 9:
Starting discharge voltage is increased when CFL is operating at lower
temperature. Please check the characteristics of inverter before applying.
