TechNews 15th May - Samsung Display showcases display panel using next-generation self-emitting display technology QD-LED (Quantum Dot LED) at SID Display Week 2024.
OLED is currently the only commercially available self-emitting display technology, but due to the use of organic light-emitting materials, OLED has natural defects such as burn-in and aging, and brightness is also limited; Quantum dot display technology already in mass production are based on photoluminescence principle, requiring excitation from a light source to improve color performance.
QD-LED combines the high efficiency of self-emitting technology with quantum dots' high color accuracy and wide color gamut, directly emitting light through current drive, and due to the use of inorganic quantum dots, the stability of the light-emitting material is higher than OLED.
The prototype panel exhibited by Samsung Display measures 18.2 inches, suitable for large notebook applications, with a resolution of 3200x1800 and a pixel density of 202PPI.
This QD-LED display panel uses inkjet printing, enabling large-area pixel patterning and significantly improving production efficiency.
Samsung Display's QD-LED panel is based on an environmentally friendly cadmium-free process and does not use traditional cadmium compound quantum dot materials, with the related paper winning the Annual Outstanding Paper Award at SID.
