The team developed a tabletop true 3D display based on integral imaging in 2021. The 3D display has good performances: the horizontal viewing angle is 360°, the vertical viewing angle is 68.5°, the display size is 83.5cm × 72.5cm, and the resolution is up to 7680 × 8640. It can be applied in electronic sand table, meeting and other occasions. The team applied for about 20 international and Chinese invention patents about the 3D display.
