46‐3: Distinguished Paper: 5.5‐inch Full HD Foldable AMOLED Display Based on Neutral‐Plane Splitting Concept

Abstract

Splitting of neutral plane is a promising concept for foldable displays because of reducing folding stress in each layer composing them. We verified the concept experimentally and developed a 5.5‐inch full HD foldable AMOLED display, which endured 150k inward folding cycles with a radius of 3 mm.

66‐3: Effective Foldable AMOLED Structure with Bendability and Impact Resistance

“…Thinner functional films are required to achieve high resistance to repeated bending with small radius. Optically Clear Adhesive (OCA) with low shear modulus is adopted as an adhesive between layers because the low modulus facilitates slip between layers and so reduces the stress applied to the functional films during bending [3][4][5]. To maximize stress relaxation and achieve excellent bendability, thicker or softer OCAs are effective [6].…”
