The ordinary glass is transformed into a unique touch screen. Users can touch the image suspended on the glass surface through their fingertips, which has a strong sense of science fiction and art. The glass screen only presents the projection light from the projector at a specific angle, which is refracted to the eyes of the audience, while the external environment light from other directions will not interfere with the presentation of empty and full. Therefore, even in a bright environment, the 30 inch suspension touch all-in-one machine can still perform perfect imaging and touch control: keep the picture bright, touch accurate, and perform well. The 30 inch suspension touch screen kiosk/Holographic Transparent Advertising Display is a good choice for the company's exhibition hall, exhibition, counter, business promotion activities and new product launch.
