Note 1 :

Voltage (Applied actual waveform to LCD Module) for the best contrast. The range of

minimum and maximum shows tolerance of the operating voltage. The specified contrast ratio and

Note 1 : Contrast ratio is definded as follows.

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.

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

as follows.

measured atθ= 10 ﾟ, φ=270 ﾟ on the segment which the ON signal is applied to.

measured atθ= 40 ﾟ, φ=270 ﾟ on the segment which the OFF signal is applied to.
