They offer both a compact form factor, and the ability to unfold into a larger screen.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Dual-screen devices are devices with two separate screens, one often besides the other, that can\u00a0operate\u00a0independently or collectively.
