Abstract

Described are devices and for providing an extendable screen in a portable communications device having a housing, graphics processor, and a display apparatus. The display includes a second screen portion that can be retracted or extended. A first screen portion can present a graphical output when the second portion is retracted, inactive and housed inside the housing. When the second screen portion is extended, it is coplanar with the first screen portion, and an edge of the second screen portion directly abuts an edge of the first screen portion to form a combined display screen. The graphical output can be rendered on the first screen portion in the first display configuration and, in a second format, rendered on the combined display screen.
