A blog known as “Dingjiao Digital” has reported that Tianma has successfully produced samples of dual-layer OLED displays and is expected to begin mass production in the latter half of the year. The blog suggests that Tianma’s pricing strategy could significantly alter the OLED market next year.
Currently， BOE has already commercialized dual-layer OLED screens， with the Honor Magic6 RSR Porsche Design being one of the first devices to feature this technology. It is also understood that the Huawei Mate 70 RS Non-Fictional Master will incorporate dual-layer OLED panels.
Dual-layer OLED， also referred to as Tandem OLED， enhances traditional single-layer OLEDs by incorporating an additional light-emitting layer. This innovative design distributes the light-emitting demands across two layers， significantly reducing the electric field strength on each layer and thereby slowing down the degradation of the light-emitting materials. This technological advancement is crucial for improving display longevity and performance.
Furthermore， due to the series connection of the two light-emitting layers， dual-layer OLEDs can theoretically achieve double the brightness of single-layer OLEDs. This not only provides users with a much brighter viewing experience but also addresses the light leakage issues often encountered with single-layer OLED panels， while maintaining the inherent flexibility of OLED screen technology. The potential for increased brightness and improved durability positions dual-layer OLEDs as a significant upgrade for mobile devices and other display applications.
