At this year’s Display Week, Samsung revealed its first ever true QD-LED quantum dot display, produced entirely by inkjet printing techniques without an LED (or OLED) layer. While inkjet printing has been responsible for the production of several display types over the last couple of years, Samsung’s prototype is the first to be a true quantum dot display.
Several companies including TCL and Sharp have showcased prototype models of QD-LED (also referred to as NanoLED) displays, but Samsung’s attempt is the largest coming in at 18 inches with a resolution of 3200×1800.

“While currently commercialized QD-OLEDs produce color by passing light from a blue OLED through a QD-emitting layer, QD-LEDs emit light directly from the QD RGB pixels through the current drive without an OLED,” reads Samsung’s release. “The wide color gamut and high color accuracy that is unique to QDs allows for superior viewing experience. Additionally, the stable material properties of quantum dots, make it highly efficient to manufacture and enable large-scale patterning through inkjet printing.”
While the display is still in prototype stage, QD-LED technology has been lauded as being more eco-friendly, and the inkjet printing process utilized has helped bring down production costs. According to FlatPanelsHD, QD-LED displays were tentatively thought to become commercially available in 2025 or 2026 at the earliest.
