Samsung Display Supplies Tandem OLED Laptop Panels With VESA DisplayHDR True Black 1400
Quick Report
Samsung Display announced that it has begun full-scale supply of tandem OLED panels for laptops meeting VESA's new DisplayHDR True Black 1400 certification tier. These new panels achieve peak brightness of up to 1,600 nits at the panel level, representing more than 40% higher brightness compared to conventional single-stack OLED panels, while maintaining true black levels of 0.0005 nits or lower.
The tandem OLED architecture stacks two organic emissive layers to improve light-emitting efficiency and achieve higher brightness while reducing load on each layer, extending lifespan to more than twice that of conventional OLED panels under typical operating brightness. The Lenovo Yoga Pro 9i Aura Edition (16”) earned True Black 1400 certification on July 8, with ASUS, Dell Technologies, and MSI expected to unveil products supporting the certification throughout the remainder of 2026 and into 2027.
