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.
