Abstract
A mobile electronic device such as a tablet computer is provided having flexible display panel that deforms in response to the application of pressure thereto. The tactile response of the display panel is affected by underlying structures. A bottom layer, which may be rigid, is positioned beneath, parallel to and spaced away from the flexible display panel. Elastic diaphragms or elastic bodies can be interposed between the display panel and bottom layer. A guidance matrix, which may be rigid, can be further interposed between the display panel and bottom layer, such that pressure applied to the display panel results in localized downward deformation in the area of a guidance matrix cavity. The elastic diaphragms or elastic bodies may extend into the guidance matrix cavities. These subsurface structures may be utilized to provide variable tactile response corresponding to the locations of keys on a virtual keyboard displayed on the display panel.
