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