HP is integrating Privacy Filters in its Laptop and Tablet Segments


If you are a Peeping Tom and enjoy looking at the laptop or tablet screens of other people, you are in for a surprise. You will not be able to view anything if you are taking a sneak peak on the latest HP product. This is because the company is putting integrated filters in its laptop and tablet displays this year.

The privacy filters make laptop and tablet screens visible to users in direct view of the display. If you move slightly away from the view, the screen becomes fuzzier and then virtually invisible the further you go. John Groden, director for Elitebook products at HP said that the users will not be able to see a screen from a 35 degree angle on the left or right. This feature could be handy in planes, airports or cafes, where sensitive information on the laptop could be visible to others.

“Security is especially important to corporate users, and this technology will prevent visual hacking,” which is a growing threat, Groden said.

Unlike third party filters available in the market, HP’s filter can be disabled by pressing a button on the laptop and make the screen visible from wider viewing angles. This becomes particularly handy when multiple viewers are watching movies on a laptop. HP’s integration of an internal privacy film in the computer screen differentiates it from other technologies in the market today. Current filters available in the market were all external and they had to be attached on to the laptop or tablet screen.

The internal privacy filter technology was developed in conjunction with 3M, which sells external privacy filters. The integrated privacy filter is connected to the motherboard and works with the CPU and GPU to enable it to be turned on and off. That also helps keep the color, brightness and refresh rate intact when the screen is in privacy mode. Overall, it will provide a better visual experience than external privacy filters, which can lower the brightness of a screen.

If you have doubts about the filter interfering with the screen resolution, you can quell them as they are non-intrusive. The new technology could become available this year first in 14-inch laptops, which are HP’s best-selling PCs. It will be an optional feature that could raise the price of a laptop. The technology will ultimately be added to more portable products later in the year, Groden said.
