Samsung Display announced that it has commercialized a new foldable OLED display that is the first to achieve a curvature radius of 1.4R mm. This display will be adopted in Samsung's Galaxy Z Fold2 5G (7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED) with an Ultra-Thin Glass (UTG) cover glass.
Samsung says that in order to minimize the folding stress that is increased in such a small folding radius, the company has optimized a series of technologies related to the material of the display, the panel design and the module assembly, so that the multi-layered structure will function like a cushion when the panel is folded.
Samsung Display commissioned Bureau Veritas, a global test, inspection and certification company, to verify 200,000 foldings of its 1.4R foldable OLED display. In addition, Samsung Display has received Eye Care Display certification from SGS. The new display has achieved an improved emission level for blue light of only 6.5%.
