Abstract:
Provided is a Maxwellian view display which uses a space-time multiplexing scheme and widens a field of view, thereby having a degree of freedom within a set area instead of a fixed position while maintaining the advantage of the existing Maxwellian view, in which a clear image can be observed irrespective of the difference in individual ability for focal point adjustment since the focal point does not need to be adjusted. According to an embodiment of the present invention, a display includes: a light source unit for changing the position of a point light source according to time; a first lens for converting the light emitted from the light source unit to be parallel; an image generating unit for generating an image using the parallel light incident from the first lens; and a second lens for focusing the image generated by the image generating unit.
