Abstract An electronic display device having a layered monolithic sheet-form structure with a rectangular shape, rounded corners, a thickness under 1.5 mm, and a smooth outer surface. The layered structure includes a first optically transparent layer with Young's modulus of at least 1 GPa, a second optically transparent or translucent layer, and a third opaque heat-conductive layer. A light emitting region contains a two-dimensional pixel array of at least one million individually addressable organic light emitting diodes (OLEDs) arranged with a density of at least 300 pixels per inch across a 10-30 centimeter dimension. Each pixel contains red, green, and blue OLEDs sized from 1 to 300 micrometers. The array covers over 90% of the device area. Adhesive layers are positioned on both sides of the array. The structure has a longitudinal fold area allowing repetitive folding with a 1-5 mm radius of curvature and at least one transparent area.
