2.6. Power Supply ON/OFF Sequence

2.6.1. ON Sequence

2.6.2. OFF Sequence

Please maintain the above sequence when turning on and off the power supply of the

module.

If DISPOFF is supplied to the module while internal alternate signal for LCD driving (M) is

unstable, DC component will be supplied to the LCD panel. This may cause damage the

LCD module.

Luminance of Module L IL=3.0mA 70 90 - cd/m

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 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 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.

Note 2 :The time that the luminance level reaches 90% of the saturation level from 0%

when ON signal is applied.

Note 3 :The time that the luminance level reaches 10% of the saturation level from

100% when OFF signal is applied.

Note 4 :Definition of Driving Voltage VOD

Assuming that the typical driving waveforms shown below are applied to the LCD

Panel at 1/A Duty - 1/B Bias (A: Duty Number, B: Bias Number). Driving voltage

VOD is definded as the voltage VO-P when the contrast ratio (CR=LON / LOFF) is at its

maximum.
