[Note]
1) DATA is latched at fall edge of DCLK in this timing specification.
2) Polarities of HD and VD are negative in this specification.
3) DENA (Data Enable) should always be positive polarity as shown in the timing specification.
4) DCLK should appear during all invalid period, and HD should appear during invalid period of frame cycle.
5) Accepted only 640 data and 480 lines.
6) REV should be stable during operation.

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 is measured
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 average of 9 luminance values measured at each
point shown above after 20 minutes power on with the all ON pattern adjusted to maximum
contrast and the dimming control of 100%. ( maximum brightness )
Note 5 : CFL Life is defined as time period that the actual luminance becomes 50% or lower of its
initial value.
The Average life time of CFL is defined as the time when half or more of the testing CFLs
have become less bright than 50% of the initial brightness at continuous operation.
