What Is a Hologram Display?
Hologram Displays are a revolution in advanced technology for the 21st century, a technology that offers a new paradigm for visual communication.
It enables the representation of information in three dimensions, bringing depth and a three-dimensional feel that cannot be captured by conventional two-dimensional displays. Hologram Displays are the key to futuristic interaction and provide opportunities for effective presentation and engagement.
This technology contributes to innovation and competitiveness in the industry and opens the door to new business development.
Uses of Hologram Displays
Hologram Display technology is expected to be used in a variety of industries and situations due to its unique three-dimensional presentation capabilities.
1. Medical Field
In the medical field, three-dimensional displays of image data from MRI and CT scans enable more detailed diagnosis and surgical planning. In medical education, Hologram Displays may also be used to help deepen understanding of anatomy.
2. Entertainment
Increasingly, holographic displays are being used in movies, games, and music events. Especially in live concerts, holograms can be used to recreate deceased artists to create a realistic performance.
3. Actual Stores and Exhibitions
Realistic 3D models can be displayed to showcase and advertise new products to attract the attention of consumers and visitors.
Principle of Hologram Displays
Hologram Displays are gaining attention as a technology for visually conveying three-dimensional information. Typical principles and models are as follows
1. Blade Rotation Type
In this method, images are projected onto blades rotating at high speed to produce three-dimensional images. A series of images are projected onto the blades, utilizing the visual afterimage effect to produce images that appear to be floating in the air.
2. Pepper Ghost Type
This is a classic optical illusion method which uses a transparent plane (usually glass or transparent plastic) to reflect the image of an object to produce an effect that makes the real object appear to float. It is mainly known for use in entertainment situations, where objects appear to float in the air when viewed from certain angles.
3. Vapor Depiction Type
This method projects light onto fog or vapor to produce an image floating in the air. This method is particularly suitable for outdoor events and shows, and can produce large-scale 3D images.
4. 3D Hologram Type
This method records interference patterns of light from objects and reproduces them to generate true 3D images. By utilizing interference and diffraction of light, 3D information of objects can be precisely reproduced, and very realistic 3D images can be enjoyed.
5. Retinal Display
This display technology projects images directly onto the user’s retina. It has the form of a headset or glasses and can display high resolution. It can also be mixed with external images to provide an augmented reality (AR)-like experience.

Advantages of Hologram Displays
As Hologram Display technology has evolved in recent years, its use has expanded in many areas. This is due to the many advantages of this technology. Below are some of the major advantages of Hologram Displays.
1. Three-Dimensional Visual Experience
One of the most obvious advantages is the visual experience of a true three-dimensional image. Users can intuitively perceive the front, back, and height of objects, unlike 2D flat displays.
2. Real-Time Interaction
Modern Hologram Displays, when combined with technologies such as haptic feedback and gesture recognition, enable real-time interaction. This provides a more immersive experience.
3. Space Savings
Since there is no need to display physical objects, exhibition space and storage can be saved. Especially in situations such as commercial facilities and exhibitions, information can be communicated without feeling physically restricted.
4. Advanced Presentation
Complex data and structures can be visually presented in a 3D form, making presentations conducive to comprehension. This is expected to be especially useful in specialized fields such as medicine, architecture, and design.
5. A New Form of Entertainment
Hologram Displays offer new experiences in the world of entertainment. Used in concerts, on stage, and in attractions, they can provide audiences with unprecedented shows.
6. Reduced Environmental Impact
The environmental impact can be reduced by eliminating the need to produce and transport physical materials and models. This also contributes to the creation of a sustainable society.
