2011 Dual Views

This is a pure software solution to enable dual views on common TN LCDs.
We can show two different arbitrarily images on two customized view angles.



As you know TN LCDs shows unintended colors when you're looking at it from sides.
This is because liquid crystals (LC) in display is rotated in horizontally as the below image illustrates. Thus, humans perceive different brightness over different view angles.



This graph illustrates brightness variances over different view angles and
there are several intersection points.
Those intersections enable to hide / show set of specific range of colors.
