Note 5: Background colour of the LCD changes depending on temperature. Between
40-50¡C optical characteristics of the LCD like contast and viewing angle
change but the display remains readable.
Note 6: Storage at -20¡C < 48 hr, at 60¡C < 168 hr
Note 7: Measurement after 10 minutes of CFL operating. Brightness control at 100%
Note 8: Need to make sure of flickering and rippling of display when setting the
FRAME Frequency in your set.
Note 9: Starting discharge voltage is increased when LCM is operating at lower
temperature. Please check the characteristics of inverter before applying.
