摘要： A stretchable electronic display comprising a substrate sheet of optically transmissive elastic material less than 1.5 mm thick with over 10% elastic range. The sheet has a display region occupying over 50% of its area and a peripheral region. A two-dimensional grid of flexible electrical connectors is disposed within the display region, defining connection nodes and openings. An array of 1-300 μm digitally addressable solid-state light emitting devices are mounted on heat conductive support pads associated with the grid nodes. The substrate sheet is configured for repetitive and reversible stretching along at least one dimension. The display includes an adhesive layer coextensive with the substrate sheet and may have the grid of connectors embedded in the substrate. The light emitting devices can be micro LEDs or OLEDs with over 40000 per square meter average density. The substrate sheet may be moisture impermeable and foldable to a tight radius.

The second CCT is less than the first CCT; a difference between the first and second CCTs is at least 10,000K. The first light spectrum may have a first emission peak in a range of 450 to 480 nm and a second emission peak in a range of 380 to 420 nm.
