Bezel design guidelines
This topic provides bezel design guidelines for multi-touch hardware solutions.
Tablet Systems include Slates and Convertible Notebooks. These are required to have flush bezel. Flush bezels are also called Edge to Edge glass.
The next image shows a flush bezel that is a cutaway on edge view. If there is a non-active border area between display area and bezel area, the non-active border area is to be considered as part of the bezel area for this illustration and bezel guidance for flush bezels. For details on flush bezel, refer to Device.Digitizer.Touch.Bezel in Device.Digitizer Requirements.
For a tablet system, the main purpose of the bezel and non-active border area is to allow enough space for users to grip the device to reduce accidental touches. Flush bezel guidance is provided below under the heading Flush Bezel.
Non-Tablet Systems include All-In-Ones and Clamshells, and these can have non-flush bezels.
The next illustration shows a non-flush bezel. The bezel is higher than the display area.
Non-tablets are not required to have a flush bezel, but if the bezel is not flush and introduces a raised edge, a 20 mm border area must be implemented to allow for uninterrupted edge access. For details on the requirements on non-flush bezel devices, refer to Device.Digitizer.Touch.Bezel in Device.Digitizer Requirements and System.Client.Tablet.BezelWidth in Windows Hardware Certification Requirements.
