Abstract
A wearable display apparatus is provided. The wearable display apparatus includes: a substrate having first and second surfaces; a display component on the first surface; a surface acoustic wave transmission layer on the second surface; a surface acoustic wave input transducer configured to send out a first surface acoustic wave; a surface acoustic wave output transducer on the surface acoustic wave transmission layer, each surface acoustic wave output transducer and a corresponding surface acoustic wave input transducer being at an edge of the substrate to be adjacent to and spaced apart from each other, and each surface acoustic wave output transducer being configured to receive a second surface acoustic wave resulted from the first surface acoustic wave being transmitted and modulated by the surface acoustic wave transmission layer; and a control device, configured to control a target area of the display component to display.
