I have this small lcd display
http://www.sharpsme.com/Page.aspx/europe/en/part/LQ043T3DX02/
and i've read something about gamma correction (correct me if i'm
wrong)....In lcd display gamma correction is performed by lcd drive
circuit: it applies an ac voltage in lc cell to obtain desidered
Transmittivity/voltage characteristics (transmittivity/voltage without
correction is a sigmoidal fuction). How can i know corrected function?
is it linear or power-law (as crt)?
Another question:
i've read this relationship:
backlight_luminance*transmittivity=output_luminance. If transmittivity
is a linear function, when is more useful a contrast change respect to
a backlight_luminance change? Backlight_luminance change is more power
saving, so i can obtain the same output result with less power...or
not?
Thanks for the help (i'm new in this field, so excuse me for the
questions)
