An image projection device includes: a panel unit configured to emit light rays; a projection optical system configured to receive the light rays emitted from the panel unit and to refract the light rays; a reflection unit having a reflection surface for receiving the light rays refracted by the projection optical system and reflecting the light rays; and a screen unit configured to display an image upon receiving the light rays reflected from the reflection surface. The panel unit, the projection optical system, the reflection unit, and the screen unit are arranged such that a distance of a shortest path among paths extending from the panel unit to the reflection unit through the projection optical system along a predetermined linear axis is longer than a distance of a longest path among paths extending from the reflection unit to the screen unit along the predetermined linear axis.

Image projection device

A holographic image display device according to one embodiment comprises: an image display unit on which a holographic image is displayed; and a spatial impression providing unit which forms a space surrounding the holographic image, and includes a transparent color material such that the space looks colored and the holographic image can be recognized from the outside.

Holographic image display device

According to one embodiment of the present disclosure, a method for displaying an image on a multi-display device including two or more displays comprises determining whether the image includes a boundary area image to be displayed over a boundary area between a first display and a second display adjacent to the first display; and inserting dummy data into the image so that the image has an increased size and the dummy data is displayed on a position corresponding to the boundary area.

Image display method

A method in accordance with an embodiment is performed by a control apparatus. The method includes obtaining, when applications having a region within which the applications are overlapped with each other are displayed on the touch display device, information that one application of the applications is displayed to cover the other application of the applications or that said one application is displayed to be covered by the other application within the region; determining, based on the obtained information, touch sensing cycles for touch sensors among a plurality of touch sensors embedded in the touch display device to be different from each other, each of said at least two touch sensors sensing a corresponding part within an entire region where the applications are displayed on the touch display device; and controlling each of said at least two touch sensors to perform a sensing operation based on its touch sensing cycle.
