For an average visitor at CES 2024, and to most tech aficionados back home, QD-OLED and micro-LED may have been the biggest TV display tech takeaways. But it turns out Sharp Display Technology Corporation was not quite content with that. The tech company quietly showcased a QDEL display in a portable 12-inch size, which on its merit is termed the future of TV displays.
We may have had a slight idea that there was a possibility of QDEL TVs coming to CES, while most of us were back longing for the concept, Digital Trends’ Caleb Denison was privy to the newest in the display technology when Sharp revealed the first QDEL display to a small group of CES attendees in the fag end of the event. Sharp also showed off a 30-inch display prototype as a proof of QDEL display tech scalability.
For those unaware, QDEL stands for Quantum Dot Electroluminescent. It essentially uses the same quantum-dot tech that QLED TVs use but there is a difference in how the two work for the better of the viewer. Typically, the quantum dots in the QLED TVs absorb light from an LED or OLED (as its light source) to convert it into color; the QDEL display on the other hand uses light directly from electricity input to display color; eliminating the need for an additional light source.
A QDEL screen thus does not require a LED or an OLED backlight to create color or brightness. The quantum dots themselves are modified to create color and pure picture using sub-pixels with dedicated red, blue and green colors. This means QDEL TV, when made, would be able to deliver far richer black, accurate color, and brightness than OLEDs over a long time, which OLEDs have been engineered to do. But because of being organic material OLED cannot do it over a long time.

Big claim that Denison makes, through input from Sharp, is that QDEL could be mass produced soon owing to their easy manufacturing method, which is similar to that of LEDs. This would mean the QDEL displays could be made quicker and at relatively lesser price spike. That said, there is no information on when QDEL TVs will hit the market, but there is speculation that the display tech could first penetrate onto screens on wearables, phones, laptops et al, before reaching the TVs.
