An industry insider says that Samsung Display has developed a screen that will support UDC. The gap between pixels was made wider to allow light to pass through. Even so, special algorithms are needed to correct the image as light is refracted by the OLED display layer. The camera module will be supplied by Samsung LSI.

The Samsung Galaxy Z Fold3 is expected to be unveiled in the third quarter of 2021. The adoption of UDC will help solidify its position as the new flagship (while the Galaxy Note lines are getting merged).
