According to South Korean media reports on April 15, Samsung Display has achieved a breakthrough in its 8.6-generation OLED panel production for IT applications, with the yield rate now exceeding 85% and approaching the industry's "golden yield" benchmark of 90%. Mass production is expected to begin between June and July.
The panels produced are set to be supplied to Apple for its upcoming 14-inch and 16-inch MacBook Pro models, with an estimated supply volume of approximately 2 million units this year.
Samsung Display is currently manufacturing test samples. A sample shipment ceremony was held on March 16, and volume shipments are scheduled to start as early as June. Given that it takes roughly 10 weeks from the input of the mother glass substrate to the completion of module production, mother glass input is expected to commence in May, with mass production of panels beginning no later than July.
In 2023, Samsung Display announced an investment of approximately 4.1 trillion Korean won to build its 8.6-generation production line, which has a designed monthly capacity of 15,000 mother glass sheets. Currently, only one line with a monthly capacity of 7,500 sheets is in operation. Once fully matured, the facility is projected to support an annual production capacity of around 5 million panels. With mass production starting in June or July, the actual operational period this year will be approximately six months. Based on the current 85% yield rate, the maximum output for 2026 is estimated at 1.9 million to 2.1 million panels.
Demand for 8.6-generation IT OLED panels is currently concentrated almost entirely on Apple. As a result, reactions from other potential customers are being closely watched. The rapid improvement in yield allows Samsung Display to achieve stable production while easing the burden of high panel prices. It also provides flexibility to utilize its remaining production lines more effectively.
An industry source noted, "The decision on whether to use the remaining production line for IT OLED or redirect it toward mobile OLED will determine the possibility of acquiring new customers. If new clients are secured, a shift toward LTPO (Low-Temperature Polycrystalline Oxide) OLED for smartphones could also be considered."
Meanwhile, Chinese panel makers are accelerating their own 8.6-generation OLED projects. BOE has already delivered its first 8.6-gen OLED samples for verification; Visionox has begun moving equipment into its facility; TCL CSOT has started ordering equipment for its 8.6-generation printed OLED project; and although LG Display (LGD) has not yet confirmed construction of an 8.6-gen line, it is reportedly considering the use of its proprietary eLEAP technology for large-size OLED production.
