Need to make sure of flickering and rippling of display when setting the FRAME Frequency in your set. Background colour of the LCD changes depending on temperature. Between 40-50C optical characteristics of the LCD like contast and viewing angle change but the display remains readable. Higher starting voltage of CFL and higher LCD driving voltage are needed while operating at 0C. The lifetime of CFL will be reduced at 0C Storage at -20C < 48 hr, Ta at 60C < 168 hr Measurement after 10 minutes of CFL operating. Brightness control100% Starting discharge voltage is increased when LCM is operating at lower temperature. Please check the characteristics of inverter before applying.
