Within no conductor closed. (CCFT only)
*1 It is recommended that I
L
be not more than 5.5mArms so that heat radiation of CCFT
backlight may least affect the display quality.
*2 Power consumption excluded inverter loss.
*3 The circuit voltage(V
S
) of the inverter should be designed to have some margin, because VS
may be increased due to the leak current in case of the LCD module.
*4 Average life time of CCFT will be decreased when LCD is operating at lower temperature.
