韩媒：京东方内蒙古B6工厂或将生产MLED

Core Viewpoint - The article highlights that ULVAC has won a bid to supply a sputtering machine for the MLED BP equipment upgrade and technical transformation project for Yuansheng Optoelectronics, a subsidiary of BOE Technology Group [2][5]. Company Overview - Yuansheng Optoelectronics is a wholly-owned subsidiary of BOE, operating the B6 factory in Inner Mongolia, which began operations in 2013 and is capable of producing 5.5-generation LCD and rigid OLED panels. The LCD panels are primarily used in automotive displays and medical devices, while OLED products focus on mobile devices [5]. - The sputtering machine is a Physical Vapor Deposition (PVD) device used to create thin films on substrates in a vacuum environment, essential for constructing circuits on the backplane (BP) of Mini and Micro LED chips [5]. Equipment Details - The specific equipment being supplied is the SMD-1500 sputtering machine, suitable for 5.5-generation glass substrates measuring 1300 mm x 1500 mm. Although the price of the equipment was not disclosed, it was previously reported that similar machines were sold for 490 million KRW each [6]. - This collaboration between ULVAC and BOE is not new, as they have a history of working together in the equipment supply sector. The current delivery of a single sputtering machine is likely aimed at performance validation for MLED BP production processes [6].
