Microsoft filed a patent back in 2018, with the purpose of ameliorating common quality issues that dual-screen devices face.
The patent, titled “Selectively Displayable Multiple Display Mode For A GUI”, was published by USPTO today, on July 11th 2019.
Apps generally lack awareness of how programs are displayed on a dual-screen device, thus leading to issues in the appearance of text breaks, toolbars and panels.
The seam between displays may obscure or break up relevant content, thereby causing great inconvenience when gaming, as well as editing videos and images, for example.
Microsoft looks to resolve this issue by intelligently choosing to display important content on only one screen, versus automatically displaying them across both screens.
The patent description includes as follows:
While the hinged mobile computing device is depicted with the primary and secondary displays in a side-by-side orientation, it will be appreciated that other suitable arrangements, such as a top-to-bottom orientation, may be used to display the GUI in the multiple display mode.
As discussed above, when displaying the GUI in the multiple display mode, the primary view on the primary display may include all or a subset of the content of the launch window of the GUI, i.e., the main content of the GUI, and the secondary view on the secondary display may include a subset or none of the content of the launch window of the GUI, i.e., relevant information related to the main content. Typically, the main content and relevant information are different from each other, and also each is different in a respect from the originally presented content in the launch window for the application program. The main content and relevant information may alternatively be referred to as first content and second content.
Microsoft’s upcoming Centaurus laptop will have two 9-inch screens with a 4:3 aspect ratio, 1,440-by-1,920 pixels with a PPI (pixel density) of 267. The device will run WCOS (Windows Core OS) with a dual display UI, will be an always-connected LTE or 5G device powered by 10nm Intel Lakefield processors, and will run Android apps.
