BOE developed its own crease-less foldable OLED display

BOE announced that it has developed a new crease-less (or zero-line) foldable OLED display, which it brands as BOE Glaze Fold. BOE says that the new technology reduces the crease visibility (and feel) by over 40%.

The visible crease has been one of the major foldable OLED adoption hurdles. Earlier this year Samsung Display was first to demonstrate a crease-less foldable OLED. Reportedly, SDC's technology will be utilized by Samsung in their 2026 foldable smartphone - and also by Apple in their 2026 foldable iPhone.

BOE's crease-less OLED was enabled by a multi-neutral-layer architecture design, that performs better than the standard single-neutral-layer display. Using a gradient modulus design, the new multi-layer architecture helps the stress to be spread out on several layers, and so reduces the peak stress and finally stops the deformation that quickly happens with folding displays. 

BOE also says that it has reduces the thickness of the various layers in the displays, and made them more integrated, which also helped reduce the stress during folding, and also improved the overall flexibility. To achieve even better results, BOE's display engineer collaborated with its module engineers to create a new hinge design to increase stress compensation, another mechanical factor that causes a visible crease.
