Please maintain the above sequence when turning on and off the power supply of the module.
If V
is supplied to the module while internal alternate signal for LCD driving (M) is unstable or
EE
RESET is active, DC component will be supplied to the LCD panel. This may cause damage to
the LCD module.

Note 1 : The voltage ( r.m.s. ) to maintain the electric discharge of the lamp. It is measured after lighting for
3 minutes .
Note 2 : The current ( r.m.s. ) to flow through the lamp with the electric discharge. It i s mea s ured after
lighting for 3 minutes .
Note 3 : The voltage at starting the electric discharge when the voltage is increased gradually from 0V.
Note 4 : Surface Luminance is specified by the initial data of luminance measured at the center of display
surface after 20 minutes power on. ( All ON pattern )
Note 5 : CFL life is defined as the time for which the initial luminance is attenuated by 50% of the
luminance value. Average Life representes the time elapsed at the point of time when the residual
ratio becomes below 50% when plural lamps are lighted in comparison with the definition of life
mentioned above.
