<p>A dynamic raster device, comprising: a first substrate (11), first electrodes (12), second electrodes (14), a raster material (15), third electrodes (16), a second substrate (17) and a control module, wherein the first electrodes (12) are spaced apart from each other and are arranged on a first surface of the first substrate (11) periodically in parallel, an insulating strip block (13) is arranged in a gap between two adjacent first electrodes (12), the second electrodes (14) are arranged on an upper surface of each insulating strip block (13), the second electrodes (14) which are in different cycles and have the same ordinal position are electrically connected to the other control signal output end of the control module, and the control module is used for receiving human eye position information in real time and independently controlling the voltage between the third electrodes (16) and the first electrodes (12), and the voltage between the third electrodes (16) and the second electrodes (14), according to the human eye position information. By means of the method, a more comprehensive coverage of a strip shape of a raster can be realized, the frequency of wire jumping of single-layer strip-shaped electrodes can be reduced, and the manufacturing difficulty of the raster can be reduced.</p> |
