With the increasing use of tablet PCs, laptops and smartphones to view and share video, wide viewing angle performance is increasingly becoming a selling point.
But display viewing angles of 170 degrees are a serious concern for business users using the devices for email and other business purposes.
A recent NPD DisplaySearch report found that while in 2011, just 7% of monitors used in-plane switching (IPS), fringe field switching (FFS) and similar display panels, this figure could increase to 25% by 2015.
Already, these new IPS/FFS displays are being shipped by some of the biggest names in business desktop and mobile computing, such as LG and IBM/Lenovo.
With these new display technologies, a privacy filter is essential for anyone using a laptop to work in a public place, both to prevent personal embarrassment and to control access to company and client information.
Dealers have a responsibility to educate their customers on this risk and draw their attention to the fact that privacy filters provide a simple, convenient and low-cost solution.
