Brightness control	The value under user mode
	Set to The value under user mode, which allows that the brightest
User contrast control	two of 32 linear distributed gray-scales (0～ 700mv) can be
	distinguished.

Measurement systems

The units of measure stated in this document are listed below: 1 gamma = 1 nano tesla

1 tesla = 10,000 gauss cm = in x 2.54

Lb = kg x 2.2

Degrees F = [°C x 1.8] + 32 Degrees C = [°F - 32]/1.8 u' = 4x/(-2x + 12y + 3)

v' = 9y/(-2x + 12y + 3)

x = (27u'/4)/[(9u'/2) - 12v' + 9] y = (3v')/[(9u'/2) - 12v' + 9] nits = cd/(m2) = Ft-L x 3.426 lux = foot-candle x 10.76
