77‐5: <i>Late‐News Paper:</i> Quantitative Assessment of Hinge Creases in Folding Devices

We present a novel, quantitative method for assessing cosmetic defects in folding devices, with a primary focus on hinge region creases which induce tactile and optical distortions. The technique applies to a range of devices, including foldable phones and IT devices showcasing diverse hinge designs from elliptical to tear drop.
