Abstract
A flexible display device that can conform to complex curved surfaces, and methods for manufacturing said display device, are disclosed herein. The display device utilizes a Miura-ori origami structure that, in a folded or at least partially folded configuration, is able to conform to complex curved surfaces. The Miura-ori structure involves folding a two-dimensional substrate in accordance with crease lines comprising a tessellation of parallelograms. Each cell of the tessellation pattern can include one or more luminous elements (LEDs, OLEDs, etc.) bonded to circuit elements embedded within the flexible substrate (e.g., Parylene-C).
