Very dark, yet large viewing angle

What is possible with screening films, one knows of the great versions for laptops. This here is the great unfortunately hardly comparable. Even by just looking at the front it is as dark as sunglasses. She swallows roughly more than 50% of light. If you then move to the side, the screen is dark until an angle which goes far beyond the from which someone looks from the next seat on the train at the display. This privacy film is completely useless for my purposes.
