Abstract
In an example implementation, a touch-sensitive illuminating display includes a transparent flexible touch layer, a transparent top conductive layer adjacent the flexible touch layer, a bottom conductive layer, and an electroluminescent layer and variable-thickness dielectric layer sandwiched between the top and bottom conductive layers. Pressure against the flexible touch layer is to reduce the dielectric layer thickness and bring the top and bottom conductive layers closer together, causing the electroluminescent layer to emit light where the pressure is applied.
