That can work if you put for every pixel, 2 pixels next to eachother the left pixel if for looking direct at it, the right pixel for looking from the side. Than you can put a filter over it that is just transparent abobe the left pixels, so you can see it from the front, but is blocked on the sides so you cant see it from an angle.
Above the right pixels, the filter is made to reflect the light from those pixels to a 45 degrees angle
