Samsung Display showcased a next-generation display technology called QD-LED (quantum dot LED) at the Society for Information Display (SID) Display Week 2024. Currently, OLED is the only commercially available self-luminous display tech, but it suffers from screen burn-in, aging, and limited brightness due to organic materials.
OLED suffers from screen burn-in and limited brightness , but not QD-LED
Existing quantum dot displays use photoluminescence, requiring a light source to enhance color. QD-LED combines high efficiency of self-luminous displays with the superior color accuracy and wide color gamut of quantum dots. It emits light directly through current and boasts higher material stability than OLED due to inorganic quantum dots.
Samsung’s prototype QD-LED panel measures 18.2 inches, ideal for large laptops, with a resolution of 3200×1800 and a pixel density of 202PPI. This panel utilizes inkjet printing for large-area pixel patterning, significantly improving production efficiency.
Samsung’s environmentally friendly QD-LED panel avoids traditional cadmium compound quantum dots and relies on a cadmium-free process. Notably, the related paper received the prestigious “Annual Outstanding Paper Award” from SID.
