Samsung Display showed a lot of innovations around their OLED technologies, but only one microLED demo. This was a stretchable display designed for automotive or wearable devices.

At Display Week 2025, they showed a similar demo in an 11-inch form factor with 120 PPI and 25% stretchability using microLEDs that were 15 x 25 microns in size (See video summary here). These displays are able to stretch in all three dimensions. However, the company acknowledged that the pixel density and luminance in the stretched region was lower, so they worked to improve this over the last year.

The company showed an improved display in their booth this year. It remains 11 inches but has increased the PPI to 200, which they claim is the highest to date. Stretchability was 30% with a deformation height of 42mm (video).

To address the reduction in luminance in the stretched region, Samsung Display added three strain sensors to the display (paper 102-3). For electrical interconnection, they fabricated a serpentine-type electrode in Aluminum. This allows for up to 50% elongation. All were embedded into an elastomeric material to ensure its durability.

In paper 87-3, they confirmed that keeping the strain below 10% did not result in any failure, even after 10K cycles. The research team also optimized the bridge structure to move from electrodes that were side-by-side to one that are top and bottom.
