What makes QD-OLED Picture Quality So Exceptional? Inside Quantum Dot Technology
The Hidden Secret Inside Stained Glass Long ago, scientists studied the stained glass windows of European cathedrals, fascinated by their vivid colors in sunlight. What they discovered were tiny semiconductor particles, tens of thousands of times thinner than a strand of hair. Invisible to the naked eye, these particles emitted brilliant colors when exposed to light. Today, we call them 'Quantum Dot'.
How Quantum Dot Size Changes Light Color Scientists continued studying Quantum Dots and discovered something remarkable. They found that the color of light changes depending on the size of the particles. Smaller particles emitted blue light, while larger particles produced red light. As technology advanced, scientists learned to control the size of Quantum Dots more precisely, enabling even more accurate color expression.
Even richer color expression? Quantum Dots excelled at producing pure, vibrant colors. They converted light energy more efficiently, creating brighter and more accurate colors. This quickly caught the attention of the display industry. Compared to conventional displays, Quantum Dot technology delivers higher color purity and richer color reproduction.
The Perfect Match: OLED Meets Quantum Dot technology Building on this groundbreaking potential, in 2018, Samsung Display took on a new challenge by combining OLED technology with Quantum Dots. Unlike conventional large OLED displays that used color filters to produce color, this new approach used light emitted from OLEDs to interact directly with Quantum Dot materials and create color. This enabled even richer and more accurate color reproduction.
The World's First QD-OLED Enters Mass Production QD-OLED UNVEILED AT CES 2022 Real Journey of QD Display After years of research, QD-OLED finally made its debut in November 2021. It was adopted in TVs and monitors, quickly gaining traction in the premium display market. With outstanding color reproduction, deep blacks, fast response times, and wide viewing angles, QD-OLED quickly emerged as a leading next-generation display technology.
The Evolution of QD-OLED Continues Quantum Black™ V-Stripe Penta Tandem™ Since its launch, QD-OLED has continued to evolve rapidly. Products in various sizes have been introduced, along with high-resolution and high refresh rate models, delivering even stronger performance. More recently, advanced technologies such as Penta Tandem™, V-Stripe, and Quantum Black™ have been introduced. A new era of QD-OLED has truly begun.
How Tiny Particles Changed the Way We See From the hidden secret of stained glass came Quantum Dots, tiny particles of light and color. What began as a microscopic discovery has evolved through decades of research and innovation into today's high-performance QD-OLED. Samsung Display continues driving display innovation toward sharper, more immersive viewing experiences.
