Dell on Wednesday introduced a Latitude notebook with a privacy screen that reduces side viewing angles so the display cannot be easily read by people sitting next to the user.
The Latitude E6400 contains software that creates an angle-reducing pixel-based pattern on the screen. The screen has a 30-degree viewing zone in front, but for people more than 15 degrees on either side, the display is white.
Despite the alteration, Dell said there's minimal impact on display brightness, and the technology eliminates the need for a separate plastic screen insert when more privacy is needed. The feature is activated either through a key-combination on the keyboard or Dell's ControlPoint software.
In launching the feature, Dell is targeting businesspeople who spend lots of time on the road and find themselves working in airports or other public places. The option costs an additional $139.
In addition to the new Latitude add-on, Dell unveiled mobile workstations that the company said are its most powerful to date. The Dell Precision M6400 and M6400 Covet feature twice the memory and substantially more storage than similar Dell systems currently available.
The Precision M6400, which is available as of Wednesday, includes an Intel Core 2 Duo quad-core processor, up to 16 GB of memory, and up to 1 GB of graphics memory. The system supports up to two hard drives with optional RAID 0 or RAID 1 configuration. Pricing starts at $2,599.
The M6400 Covet will also include a quad-core Intel processor. Further specifications and pricing were not available. The system is expected to be available by the end of the year.
