Definition of optical data, see page 84 Applied to NotDISP.OFF, FRAME, LOAD, CP, UD0-UD3, LD0-LD3 FRAME=140Hz, UD0-UD3=0.1.0.1...LD0-LD3=1.0.1.0..VDDVEE=22.7V,T=25C Recommended LC driving voltage may fluctuate about +-1.0V by each module A higher starting voltage will be needed for CFL at 0C. Lifetime of CFL is reduced at 0C.
Note 7: Note 8: Note 9: Note 10:
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. Storage at -25C < 48 hr, at 60C < 168 hr Need to make sure of flickering and rippling of display when setting the Frame Frequency in your set Measurement after 10 minutes of CFL operating. Brightness control at 100% Starting discharge voltage is increased when LCM is operating at lower temperature. Please check the characteristics of inverter before applying.
