Title:
AIR IONIZATION DISPLAY DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/267780
Kind Code:
A1
Abstract:
An air ionization display device (10) and a control method therefor, which relate to the technical field of imaging. The air ionization display device (10) comprises: a pulse laser source (11) for generating a pulse laser beam; a beam splitter (12) for splitting the pulse laser beam into a first sub-beam and a second sub-beam; a pulse laser adjusting assembly (13) for adjusting the wavelength of the second sub-beam to obtain a third sub-beam and adjusting a time difference between the third sub-beam and the first sub-beam, so as to delay the emergence of the third sub-beam; a beam combiner (14) for combining the first sub-beam and the delayed-emergence third sub-beam to obtain a combined beam; and a light field adjusting and controlling assembly (15) for adjusting and converging the combined beam and ionizing air in a display area to form a holographic image.
