## Abstract

Disclosed is a hologram stage setting which is configured to apply a net screen of a grid network structure coated by a ceramic ball lens on the front part of a stage and directly project images, thereby enabling performance without specific limits on general multi-purpose stages instead of special stages, solving high cost problems caused by using a conventional foil screen, implementing high-resolution images, enhancing durability, and performing easy maintenance and repair. The hologram stage setting includes: a rear screen which is installed on the rear part of a stage to display a rear background image; a lower screen which is installed on the lower part of the stage to display a lower background image; a front screen which is installed on the front part of the stage to display a front hologram image; and a front hologram image projector which generates and projects the front hologram image.

## Claims

### Claim 1

A hologram stage setting, comprising:
a rear screen which is installed at the rear part of the stage to display a rear background image;
a lower screen which is installed at the lower part of the stage to display a lower background image;
a front screen which is installed at the front part of the stage to display a front hologram image; and
a front hologram image projector which generates and projects the front hologram image,
wherein the front hologram image projector is disposed at the upper front side of the front screen to directly project the front hologram image to the front screen, and
wherein the front screen includes a net screen of a grid network structure coated by a ceramic ball lens and a support member which is installed along the edge of the net screen to keep the shape of the net screen.

### Claim 2 (depends on 1)

The hologram stage setting of claim 1, wherein the net screen has a tensile strength of 150 kg/mm2 or more and an elongation of 4% or less.

### Claim 3 (depends on 2)

The hologram stage setting of claim 2, wherein the ceramic ball lens coating the net screen has a particle size of 70 μm.

### Claim 4 (depends on 3)

The hologram stage setting of claim 3, wherein the adhesion of the ceramic ball lens is 99% or more.

### Claim 5 (depends on 4)

The hologram stage setting of claim 4, wherein a reflection coefficient of the net screen is 3.0 Gain.
