The time that the luminance level reaches 10% of the saturation level from 100% when OFF signal
is applied.
Voltage (Applied actual waveform to LCD panel ,1/5 bias) for the best contrast. The range of
minimum and maximum shows tolerance of the operating voltage. The specified contrast ratio
and response time are not guaranteed over the entire range.
