Before one can experience your holographic display, you must have pre-created digital content or a computer-generated hologram.
You will require a high-definition or ultra-high-definition screen to reflect your computer-generated hologram through glass optics.
The glass optics must have special coatings to improve throughput. The coating also prevents backward reflections that might lead to the formation of a defective display.
Your angle of view and viewing position will determine the clarity and quality of the 3D image.
You can view your holographic display image from different viewing angles. As you change your viewing position, the displayed image will shift accordingly. Amazing!
Types of Holographic Display Based On Applied Technologies
Laser Plasma Holographic Display
This type of hologram projection uses powerful lasers and does not require any screen to display images. The lasers induce plasma that will form your holographic images in the air!
A major drawback of this technology is its formation of low-quality images. So, if your project needs captivating high-resolution 3D displays, it’s not your best technology.
Full-Parallax, Horizontal Only Parallax | Vertical Only Parallax Displays
If you are looking for a holographic display that viewers will see irrespective of their viewing angles, go for a Full-parallax hologram projection.
The technology ensures the optical information for your 3D image display is presented in horizontal and vertical axes. A major drawback with this type of technology is that your display will require more processing power.
A compromise of a full-parallax holographic display is a horizontal or a vertical-only parallax option. With these two options, your display’s processing power will be reduced.
However, viewers will only see your image at certain horizontal or vertical angles. Between the two, the most user-friendly option is the horizontal-ONLY parallax. This is because human eyes naturally find horizontal viewing easier!
Micro-magnetic Piston Holographic Displays
This type of holographic display uses MEMS(Micro-electro-mechanical system) technology. In this technology, microscopic pistons that move upwards and downwards represent image pixels.
The light reflections from moving pistons (“pixels”) form your 3D holographic display!
Touch-sensitive Holographic Displays
With current technological developments, there are now holograms you can touch. These holographic displays rely on haptic technology and have many applications, such as in science-fiction movies. A classic example is in the Star Wars.

Types of Holographic Displays Based On User
You can also group holographic displays based on how users can view them. They fall into three categories namely:
Head-mount Holographic Display(HMD)
As the name suggests, a head-mounted display has a special headwear or helmet with a front section for viewing a 3D image. Your HMD can come with either a monocular or a binocular.
You will find holographic HMD displays used in human-machine interfaces, medical sectors, engineering, and virtual reality industries.
Single-user Desktop Displays
These are small holographic screens with a small angle of view for single users. Because of their small displays, you must maintain a fixed viewing position for perfect viewing. So, you must sit or stand still for a clear and stable view.
Interactive Multi-user Holographic Displays
These holographic displays allow for multiple viewers. The users can interact with displayed 3-dimensional images of high resolutions.
To develop this multi-viewer display, you need full-parallax holograms. You can use multi-user holographic displays in your engineering design projects. You will also find them in the sports industry.
Advantages and Disadvantages of Holographic Display
Immersive User-Experience
One key advantage of holographic displays is the immersive experience they create.
Whenever you have a well-designed hologram floating on air, its 3D magic will instantly captivate your target audience! It is for this reason that holographic displays are popular, especially in the gaming and virtual reality industries.
Enhanced Visualization For Better Understanding
Sometimes, the best way to let people understand a complex image or design is to let them have a different viewing perspective.
This benefit makes holographic displays useful in marketing, medical, architectural, and engineering industries.
Enhances Engagement Through Interactive Communication
You can use holographic displays to enhance interactive communication when presenting a product to your potential customers.
The magical 3D display of your product will help viewers to have a wider perspective of its technical features. As a result, there will be more interaction and engagement.
Has No Application Limit in Science & Engineering
Another advantage of holographic display technology is its wide use in scientific and engineering fields, such as:
These applications enable researchers, scientists, and engineers to visualize and analyze complex three-dimensional structures with greater clarity and insight.
High Resolution
With small holographic displays, you can achieve superior image resolutions. Therefore, the technology allows you to assess and evaluate item details with high-level precision. This makes the technology useful in critical areas such as microscopy and interferometry, where detailed analysis is required.
Displays Both Depth and Perspective
With a holographic display, your target viewers can capture your presentations or objects from different angles and locations. This ensures your 3D presentations are realistic and captivating.
Boosts Artistic Expression
With holographic display technology, artists can create mind-blowing artistic displays that engage viewers like never before.
Authentication of Security Features | Prevents Forgery
Holographic display technology is also useful when you want to authenticate certain complex labels on products like currency notes. The technology, therefore, helps in the easy identification of certain counterfeit products.
Disadvantages and Limitations of Holographic Displays
Apart from its colorful advantages, the holographic display also has its fair share of disadvantages and limitations, such as:
The Viewing Angle Is Limited
With the angle of view, a holographic display has a limitation. This limitation exists because viewers can only see the formed 3D display from specific angles. If you try to shift your position, the image tends to lose clarity.
Environment Factors
You can only have a perfect holographic display where certain environmental conditions are favorable. This is because the 3D Display is sensitive to vibrations and air movements.
Temperature changes can also impact the display quality because they affect diffraction efficiency.
Difficulty in Producing Full Color Holograms.
Production of a full-color-holographic display is a major drawback that you must be aware of. This is because it is a complex and expensive undertaking.
Holographic Display Technology Is Expensive.
Investing in holographic displays is both complex and expensive. So, it will cost you more to acquire specialized hardware and software needed for data processing, storage, and 3D display. This is a major drawback when you are working on a limited budget.
