learned from BOE that on September 10, BOE’s “R&D and industrialization of high-resolution flexible and flexible AMOLED display technology for mobile applications” (hereinafter referred to as “flexible and flexible AMOLED project” ) Won the special prize of Beijing Municipal Science and Technology Progress Award. The BOE project team achieved mass production of 5 mm outward-folding flexible display screens for the first time in the world.

Naijatechnews learned that when talking about the mass production of the world’s first R5 outer-fold flexible display, BOE stated that the radius of curvature and the bending life are two important indicators to measure the bending resistance of the flexible display. “R” refers to the radius of curvature of the flexible screen; and “R5 200,000 bends” means that the flexible screen can be bent 200,000 times without damage under the condition of a radius of curvature of 5mm. This bending life is flexible The screen is a necessary condition for commercial mass production and application to flexible folding mobile phones.
According to reports, BOE pioneered the multi-neutral layer design theory in the industry, successfully designed the world’s unique multi-layer stack structure for out-folding flexible AMOLED screens and established folding test evaluation standards, achieving 200,000 yuan under the condition of a radius of curvature of 5mm. The second bending has reached the user standard, and the mass production of a 5 mm outward-fold flexible display screen is realized for the first time in the world.
