On September 10, BOE’s flexible AMOLED project won the Special Award of the Beijing Science and Technology Progress Award. The BOE project team achieved mass production of the world’s first 5mm outward folding phone.
When discussing the mass production of the world’s first R5 outward-folding flexible display, BOE stated that the radius of curvature and bending lifespan are two key indicators for measuring the bend resistance of flexible screens. The ‘R’ represents the bending radius of the flexible screen. ‘R5 200,000 bends’ means that under a 5mm bending radius, the flexible screen can withstand 200,000 bends without damage. This bending lifespan is a necessary condition for the commercial mass production of flexible screens and their application in flexible folding phones.
According to reports, BOE is the first in the industry to propose the multi-neutral layer design theory, successfully designing the world’s unique multi-layer stack structure for outward-folding flexible AMOLED screens, and establishing folding test evaluation standards.
Based on the above technological innovation breakthroughs, BOE has deployed fully flexible sixth-generation AMOLED production lines in Chengdu, Mianyang, and Chongqing. BOE Chengdu’s sixth-generation flexible line was mass-produced in October 2017, and Mianyang’s sixth-generation flexible line was also mass-produced in July 2019.
According to the report, in the first half of 2020, BOE’s flexible AMOLED display shipments accounted for 20.3% of global shipments. Motorola, LG, OPPO, and Nubia have adopted BOE flexible screens.
At present, in addition to the mobile phone field, BOE is also applying flexible display products to intelligent cockpits, business offices, smart homes, and many other fields, and continues to expand the application space of flexible OLED technology.
