Maxwellian display by using time-spatial multiplexing method

摘要

The fixed position that widens the field of view using space-time multiplexing is maintained without the need for focusing, which is the advantage of Maxwellian View. A Maxwellian display with a certain degree of freedom is provided. According to an embodiment of the present invention, a display may include a light source unit for changing a position of a point light source with time; A first lens converting light emitted from the light source unit in parallel; An image generator which generates an image using parallel light incident from the first lens; And a second lens focusing an image generated by the image generator. As a result, a clear range of images can be observed regardless of individual focusing ability, which is an advantage provided by the Maxwellian view, and a range of images that can be observed only from a fixed point of view that has been a disadvantage in the Maxwellian view. Clear zones can be observed regardless of differences in focusing capability in zones with degrees of freedom.
