HP and 3M said they will integrate built-in privacy screens into some laptops that can be turned on and off with the push of a button. Details of the 3M film were sparse, but HP said it should have it in some laptops by next year.
Currently, ensuring privacy in cramped quarters is usually handled by installing a clumsy plastic sheet that narrows the field of view to only the person directly in front of the computer. If you're on the side, you see black. But when you have to peel off that screen when it's time to show off your PowerPoint, and they often get dinged up and lost.
It’s a messy, clumsy solution. HP and 3M’s integrated privacy screen feature could make shunning prying eyes a lot more convenient and secure as you work on your Great American Science Fiction Novel in the local cafe. You don’t want your nemesis to steal your idea, after all.
