Semi-transparent semi-retroreflective film and air display device
A semi-transparent semi-retroreflective film and an air display device are provided. The air display device includes: a first polarizer and a second polarizer assembled with each other to form a cell; a semi-transparent semi-reflective structure and a semi-transparent semi-retroreflective film disposed between the first polarizer and the second polarizer; a first ¼ wave plate disposed at a side of the air display device adjacent to the first polarizer; and a second ¼ wave plate disposed between the semi-transparent semi-reflective structure and the semi-transparent semi-retroreflective film. The air display device is configured such that polarized light incident from the first polarizer, after being processed by an internal optical path of the air display device, exits from the second polarizer to form an air image at a side of the air display device away from the first polarizer.
