Sharp was demonstrating two new QDEL prototype at CES 2024. The first was 12-inch in size (you can see this in the video below), and the second a 30-inch prototype (Sharp did not allow to take photos/videos of the larger display).
Sharp did not disclose much about the display, or any commercialization plans. This seems to be an early-stage development. We do know that Sharp is using QD materials produced by Nanosys (SHOEI), and that the display is produced on an IGZO (Oxide-TFT) backplane.
