According to reports, BOE started mass producing OLED displays at its 6-Gen B12 production line in Chongqing, China. The ramp up is in stages, with the plant expected to reach full production capacity in late 2022 or early 2023.
The reports suggest that the first panels in production now will ship to Oppo for its smartphones. Actual shipments will begin by the end of 2021 (it is likely that actual production volume right now is still low).
The B12 line in Chongqing will have a full yearly capacity of 48,000 substrates, when all three lines are operational (each line has a capacity of 16,000 substrates). When the plant will run at at full capacity, BOE's OLED production capacity will reach 144,000 substrates.
