Abstract: A holographic display apparatus includes a light guide plate including an input coupler and an output coupler, a holographic image generating assembly configured to generate a holographic image and provide the holographic image to the input coupler of the light guide plate, and an image processor configured to convert source image data based on a point spread function, which is obtained for each pixel of the holographic image on an image plane, to compensate for a blur of the holographic image output through the output coupler.

Abstract: A see-through type display apparatus includes a see-through type optical system configured to transmit a first image via a first-path light, which is light traveling on a first path, to an ocular organ of a user, and a second image via a second-path light, which is light traveling on a second path, to the ocular organ of the user; and an incident light-dependent lens unit provided between the see-through type optical system and the ocular organ of the user and having different refractive powers according to characteristics of incident light, where the incident light-dependent lens unit has a positive first refractive power with respect to the first-path light and has a second refractive power different from the first refractive power with respect to the second-path light.
