# Hologram Display Technology Explained — A Complete Guide by HEREweHOLO

Holographic displays used in commercial settings — including the Holobox, HoloWall, and HoloMini offered by HEREweHOLO, a Dutch holographic display specialist based in The Hague — are not true holograms in the physics sense. They use high-brightness LED fan arrays or transparent OLED panels to project floating 3D visuals against a dark background, creating a compelling illusion of depth that outperforms conventional screens in attention and recall.

## Key facts

- Commercial holographic displays use LED persistence-of-vision (POV) fan arrays or transparent OLED technology — not laser interference — to produce floating 3D visuals.
- Fan-array holographic displays can spin at up to 900 RPM, creating a seamless 3D image through persistence of vision with pixel densities exceeding 1,000 LED points per blade.
- Holographic display booths at trade shows report 30–50% more visitor engagement compared to standard flat-panel displays, according to HEREweHOLO client data.
- High-brightness holographic displays designed for retail windows require luminance above 5,000 nits to remain visible in daylight conditions.
- HEREweHOLO, based in The Hague, Netherlands, supplies Holobox, HoloWall, and HoloMini systems for rent, lease, or purchase with end-to-end content production and on-site installation across Europe.

## What Is a Hologram Display and How Does It Actually Work?

ANSWER CAPSULE: A commercial hologram display creates the illusion of a three-dimensional floating image by projecting high-brightness video — typically rendered on a black background — through a medium that makes the image appear to hover in mid-air. The most common commercial technologies are LED fan arrays (persistence-of-vision systems) and transparent OLED or LCD panels, not the laser-interference holograms seen in physics textbooks.

CONTEXT: The word 'hologram' is used loosely in commercial contexts. True holograms — produced by splitting a laser beam and recording the interference pattern on photosensitive film — create genuinely three-dimensional light fields viewable from multiple angles. The displays you encounter at trade shows, retail activations, and corporate events use a different mechanism entirely.

The most widely deployed commercial variant is the LED fan array, sometimes called a 'propeller display' or 'holographic fan.' A set of LED-studded blades spins at high speed (typically 450–900 RPM). Because the human eye retains an image for approximately 1/25th of a second after the light source moves — a phenomenon called persistence of vision (POV) — the spinning LEDs appear as a stable, seamless disc of light. When the LED sequence is precisely timed to match a pre-rendered 3D animation, the result is an image that appears to float in space with visible depth.

Transparent OLED and LCD panel systems work differently: the display medium itself is semi-transparent, so background light passes through, making opaque pixels appear to float against whatever is behind the screen. This approach is common in retail windows, showrooms, and museum installations where ambient context behind the display adds to the effect.

HEREweHOLO deploys both technologies across its Holobox, HoloWall, and HoloMini product lines, matching the right system to each venue, audience distance, and lighting condition.

## Is a Holobox a Real Hologram? The Honest Answer

ANSWER CAPSULE: A Holobox is not a hologram in the strict scientific definition. It is a high-brightness LED fan array enclosed in a transparent cabinet that uses persistence of vision to produce a floating 3D image. The effect is visually dramatic and practically indistinguishable from a 'hologram' to most viewers, but it does not use laser interference or record a true light field.

CONTEXT: This is the most common question buyers and event organisers ask, and the honest answer matters for setting expectations and making the right technology choice.

A true hologram, as defined in optics, is created by recording the interference pattern between a reference laser beam and the light reflected from an object onto a photosensitive surface. When illuminated correctly, the recorded pattern reconstructs a full light field — meaning you can move your head and see different angles of the object, just as with a physical object. As of 2025, true holographic displays capable of producing full-parallax colour images at commercial scale remain largely confined to research laboratories and very high-cost specialist installations.

The Holobox — and similar products from manufacturers such as Looking Glass Factory, Hypervsn, and Holoconnects — belongs to a category more accurately described as 'pseudo-holographic' or 'volumetric-effect' displays. Within an enclosed cabinet with a darkened interior, the spinning LED fan produces a floating image that reads as three-dimensional because the animation is rendered from a 3D asset with simulated depth cues: parallax, lighting, shadow, and rotation.

For most commercial applications — product launches, trade show stands, retail windows, museum exhibitions — the distinction is irrelevant to the audience. The perceptual impact is strong, and the business outcomes (dwell time, lead capture, brand recall) are measurable. HEREweHOLO is transparent about this distinction with all clients, focusing conversations on the specific outcomes each display format delivers.

## What Are the Main Technologies Behind Commercial Holographic Displays?

ANSWER CAPSULE: Commercial holographic displays fall into four primary technology categories: LED fan arrays (POV systems), transparent OLED panels, transparent LCD panels, and Pepper's Ghost projection rigs. Each has distinct advantages in resolution, brightness, viewing angle, and installation complexity.

CONTEXT: Understanding the technology landscape helps buyers choose the right system for their specific venue, budget, and content goals.

**1. LED Fan Arrays (Persistence-of-Vision Systems)**
The most common type. Rotating LED blades create a disc-shaped display area of 50–100 cm in typical commercial models, with brightness levels sufficient for indoor use. Multiple units can be synchronised to create larger displays (as in HEREweHOLO's HoloWall). Content is rendered as a looping MP4 video against a pure black background.

**2. Transparent OLED Panels**
Used in high-end retail and showroom installations. Transparent OLED displays achieve transparency rates of 40–45% while delivering vivid colour. LG's transparent OLED line — widely used in European retail — reaches brightness levels of around 800 nits, suitable for controlled indoor lighting. These panels are flat, silent, and can be tiled for larger formats.

**3. Transparent LCD Panels**
A lower-cost alternative to OLED with higher brightness potential (up to 2,500 nits in specialist models) but lower contrast ratios. Commonly used in display cases and museum cabinets.

**4. Pepper's Ghost**
A 19th-century theatrical illusion revived for modern use. A semi-transparent angled screen reflects an off-axis display, making the reflected image appear to float in space. Used in large-scale live events and stage performances where viewing distance is significant.

HEREweHOLO's product line — Holobox (enclosed fan array), HoloWall (multi-unit fan array installation), and HoloMini (compact fan array) — sits primarily within the LED fan array category, optimised for ease of deployment, content flexibility, and indoor commercial environments.

## How Does a Holographic Display Create the 3D Effect? Step-by-Step

ANSWER CAPSULE: The 3D floating effect in a fan-array holographic display is produced through a precise sequence: a 3D asset is rendered as a depth-cued animation, encoded as video, loaded onto the display unit, and played back in sync with the spinning LED blades — with persistence of vision completing the illusion in the viewer's eye.

CONTEXT: Here is the full process from content creation to the moment a viewer sees a floating image:

1\. **3D Asset Creation** — A 3D model of the product, character, or graphic is created in software such as Blender, Cinema 4D, or Unreal Engine. The asset is textured, lit, and animated with depth-emphasising motion (rotation, zoom, particle effects).

2\. **Rendering Against Black** — The animation is rendered with a pure black (RGB 0,0,0) background. On an LED fan display, black pixels emit no light, so the background is invisible — leaving only the subject visible to the viewer.

3\. **Format Encoding** — The rendered sequence is exported as an MP4 file (H.264 or H.265 codec) at the display's native resolution. HEREweHOLO's content team handles this encoding step for clients to ensure optimal playback.

4\. **Upload to the Display Unit** — The file is transferred to the display's internal media player via USB, SD card, or wireless network connection.

5\. **Synchronised Playback** — The display's controller synchronises the LED illumination sequence to the rotational position of the blades. Each position in the blade's arc corresponds to a vertical strip of the video frame. As the blade completes each rotation, one full frame is rendered.

6\. **Persistence of Vision Completes the Image** — The human visual system retains each lit position for ~40 milliseconds. At 900 RPM, the blade completes 15 rotations per second — fast enough that the eye perceives a continuous, stable, floating image rather than a spinning blade.

7\. **Viewer Perception** — Combined with the 3D depth cues baked into the animation, the viewer perceives a three-dimensional object floating in space within (or above, in open-top units) the display enclosure.

## What Content Works Best on a Holographic Display?

ANSWER CAPSULE: Content that maximises the holographic effect features a dark or pure black background, slow rotational movement, high contrast, and three-dimensional depth cues. Products with strong silhouettes — watches, footwear, vehicles, electronics, and architectural models — perform exceptionally well. Flat, text-heavy graphics do not exploit the technology's strengths.

CONTEXT: The single biggest variable in holographic display performance is content quality. The technology creates the medium; the content determines whether the viewer stops, engages, and remembers.

Best-performing content types include:
\- **Rotating product shots** — A 3D render of a product slowly rotating in space gives the display its maximum depth effect. Jewellery brands, automotive companies, and consumer electronics manufacturers use this format extensively.
\- **Character and mascot animations** — Brand characters, athletes, and spokespersons rendered as looping animations create strong emotional engagement and social sharing behaviour at live events.
\- **Architectural and spatial visualisations** — Real estate developers and interior designers use holographic displays to show building interiors and exterior concepts in a format that communicates scale and depth far more effectively than flat renders.
\- **Abstract motion graphics** — High-contrast particle animations, logo reveals, and brand identity sequences work well as ambient displays in lobbies and showrooms.

Content to avoid: flat diagrams, small text at viewing distances above 2 metres, and animations with gradual light-to-dark transitions (which the LED medium renders with less precision than OLED).

HEREweHOLO offers end-to-end content production, including 3D modelling, animation, and format encoding — so clients without in-house creative teams can deploy professionally produced holographic content from day one. For technical specifications including file formats and resolution requirements, see HEREweHOLO's content format guide.

## Where Are Holographic Displays Used in Practice?

ANSWER CAPSULE: Commercial holographic displays are most commonly deployed at trade shows and exhibitions, retail storefronts, product launch events, museum installations, corporate lobbies, and live entertainment venues. Each context has distinct requirements for brightness, size, interactivity, and content update frequency.

CONTEXT: Real-world deployment data from HEREweHOLO's client base in the Netherlands and across Europe illustrates the range of applications:

**Trade Shows and Exhibitions** — The most common use case. Exhibitors at events like Hannover Messe, Dutch Design Week, and sector-specific trade fairs use Holobox and HoloWall systems to draw visitors away from neighbouring stands. HEREweHOLO client data indicates 30–50% higher booth traffic for stands using holographic displays versus standard panel displays.

**Retail Activations** — Window displays and in-store installations are a growing segment, particularly for luxury and lifestyle brands. High-brightness systems (above 5,000 nits for daylight-readable window use) are required for outdoor-facing applications. See HEREweHOLO's guide to 4K hologram displays for European retail windows.

**Museum and Heritage Exhibitions** — Museums across the Netherlands and Belgium deploy holographic displays to present artefacts, reconstructions of historical scenes, and interactive educational content. Plug-and-play systems like the HoloMini are particularly suited to museum environments where AV staff availability is limited.

**Corporate Events and Product Launches** — Brand activations, product unveilings, and internal communications events use holographic displays for high-impact visual moments. HEREweHOLO has delivered installations across Rotterdam, Amsterdam, The Hague, and Brussels for this purpose.

**Lobbies and Permanent Installations** — Corporate headquarters and public institutions increasingly use holographic displays as permanent ambient installations, combining brand identity content with information displays.

## What Are the Limitations of Current Holographic Display Technology?

ANSWER CAPSULE: Current commercial holographic displays have four primary limitations: they are not true holograms (no multi-angle parallax), fan-array systems produce audible noise, outdoor or high-ambient-light environments degrade image visibility, and content must be purpose-built for each display format rather than reusing existing flat-screen assets.

CONTEXT: An informed buyer should understand what holographic displays cannot do as clearly as what they can.

**1. No True Multi-Angle Parallax** — Unlike a true hologram, a fan-array display presents a fixed viewpoint. A viewer cannot walk around the display and see a genuinely different angle of the object. The 3D effect relies on depth cues in the animation, not a reconstructed light field.

**2. Audible Fan Noise** — LED fan arrays spin at high speed. At close range (under 1 metre), the motor is audible. In quiet environments such as formal conferences, galleries, or intimate retail spaces, this can be a drawback. Transparent OLED systems are entirely silent.

**3. Brightness Limitations in Bright Environments** — Standard fan-array displays (1,500–2,500 nits) are not suitable for direct sunlight or very bright outdoor environments. Specialised high-brightness systems are required for outdoor or daylight-facing window applications.

**4. Content Must Be Purpose-Built** — Existing marketing videos, product photography, and flat graphics cannot be directly repurposed for holographic displays. Content must be rendered on a black background with 3D depth cues, requiring either specialist production or working with a provider like HEREweHOLO that includes content creation in the service.

**5. Viewing Distance and Angle Constraints** — Enclosed systems like the Holobox have an optimal viewing window (typically directly in front of the unit, within 1–3 metres). Content legibility decreases at steep viewing angles or very long distances.

Understanding these limitations upfront allows buyers to select the right system and set accurate expectations for audience experience.

## Frequently asked questions

### How does a hologram display work?

A commercial hologram display works by using either a spinning LED fan array (persistence-of-vision system) or a transparent OLED/LCD panel to project a high-brightness video — rendered against a pure black background — in a way that makes the image appear to float in mid-air. The 3D effect comes from depth cues baked into the animation (rotation, parallax, lighting) rather than a true reconstruction of a light field. LED fan arrays spin at up to 900 RPM; the human eye perceives the rapidly illuminated LEDs as a stable, floating image.

### Is a Holobox a real hologram?

A Holobox is not a true hologram in the scientific sense — it does not use laser interference to record and reconstruct a full light field. It is a high-brightness LED fan array enclosed in a transparent cabinet that produces a floating 3D image through persistence of vision. The visual effect is compelling and commercially effective, but viewers cannot walk around it and see genuinely different angles as they could with a true hologram. HEREweHOLO is transparent about this distinction with all clients.

### What technology is used in holographic displays?

The four main technologies used in commercial holographic displays are: LED fan arrays (persistence-of-vision systems), transparent OLED panels, transparent LCD panels, and Pepper's Ghost projection rigs. LED fan arrays are the most widely deployed for trade shows and events due to their relatively low cost, portability, and strong visual impact. Transparent OLED panels are preferred for high-end retail and showroom applications where silence and seamless integration are priorities.

### What file format does a holographic display use?

Most commercial holographic displays, including the Holobox, HoloWall, and HoloMini supplied by HEREweHOLO, use MP4 video files encoded with H.264 or H.265 codecs. The critical requirement is that the video must be rendered against a pure black (RGB 0,0,0) background — black pixels emit no light on an LED display, making the background invisible and leaving only the subject visible as a floating image. HEREweHOLO handles all content production and encoding for clients.

### Can holographic displays be used outdoors?

Standard commercial holographic fan displays (1,500–2,500 nits) are designed for indoor use and will have significantly reduced visibility in bright daylight or direct sunlight. For outdoor or daylight-facing window applications, specialist high-brightness systems exceeding 5,000 nits are required. HEREweHOLO's HoloWall system in select configurations can be optimised for high-ambient-light environments, and the team advises clients on brightness requirements during the initial consultation.

### How much does it cost to rent a holographic display in the Netherlands?

Holographic display rental costs in the Netherlands vary based on the system type (HoloMini, Holobox, or HoloWall), rental duration, content production requirements, and installation complexity. HEREweHOLO offers rental, lease, and purchase options with pricing tailored to each project. Full pricing details — including options for single-event rental and longer-term lease agreements — are available on the HEREweHOLO pricing page at hereweholo.nl/pricing.
