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.

A holographic display system and an electronic device are provided. The holographic display system includes: at least a first optical module, a second optical module and a third optical module arranged sequentially in a first direction towards which the backlight is to be emitted. The first optical module is configured to transmit light of a first polarization direction, the second optical module is configured to transmit light of a second polarization direction, and the third optical module is configured to transmit light of a third polarization direction. The first polarization direction and the second polarization direction are at an angle of .sub.1, the second polarization direction and the third polarization direction are at an angle of .sub.2, and the first polarization direction and the third polarization direction are at an angle of .sub.3, .sub.3 is greater than at least one of .sub.1 and .sub.2.
