GHOST DOT 1500

The GHOST DOT 1500 is the circular transparent screen one and a half metres in diameter: 1.77 m² of surface, roughly 58,000 pixels. It is the range's intermediate diameter, and the one that settles the most real-world cases.

The last format that needs no equipment

At a metre and a half the disc stays transportable and goes up with two people, with no cherry picker and no load study. Beyond that — two metres and up — you enter installation territory: calculated rigging point, working at height, an installer on site.

So this is the format for places that want the effect without the works: agency lobby, showroom, reception area, recurring exhibition stand, a shop with good ceiling height.

Specifications

Pitch of 3.9 × 7.81 mm, density of 32,768 pixels per square metre, SMD1921 LEDs, 2,500 nits, 3,840 Hz refresh, 140° / 140° viewing angle, average consumption 240 W/m² — about 425 W in normal operation, against a theoretical 1.4 kW peak.

Distance, always

The 7.8125 mm vertical pitch needs 13.4 metres for the grid to stop being perceptible. At a metre and a half in diameter, the screen is usually seen from closer than that.

So design it as an animated light source rather than a screen. Close up you see the strips and perceive a moving texture; that is the intended effect in a lobby, it is not an information medium. If the need is a legible message, diameter is not the lever: you need a tighter pitch, and therefore a flat surface.

What transparency gives at this scale

A metre-and-a-half disc hung in front of a glass wall, a lobby perspective or a textured wall masks almost nothing. You see the architecture through it, and the image seems to float in front. That doubling is what makes the object — and it disappears entirely if the screen sits in front of a neutral background at close range.

The rule is simple: there must be depth behind. Two metres of clearance minimum between the disc and whatever is behind it, failing which the screen reads as a solid surface whatever its transparency.

Position in the range

The GHOST DOT 1000 fits a shop window. The GHOST DOT 2000 crosses body scale and becomes an architectural element. For genuinely detailed image reading you need a flat surface and a tighter pitch — see the GHOST range.

Avec un pitch de 3.9 mm, GHOST DOT 1500 couvre les distances de vision moyennes (3 à 8 m). Conçu pour un usage indoor, ce module combine 2500 nits et 3840 Hz, soit l'ensemble des paramètres attendus sur une installation B2B professionnelle.

Technical Maintenance and Configuration

To maximize the lifespan and performance of your GHOST DOT 1500 installation, several technical factors should be considered:

• Viewing Distance: Ensure the installation height and distance align with the pitch density to maintain visual cohesion and prevent pixelation for the audience.
• Controller Setup: We recommend using high-end NovaStar or Colorlight controllers to leverage the 3840Hz refresh rate effectively. Proper RCFG file configuration is essential for color calibration.
• Power Supply Stability: Maintain a stable 5V DC input. Avoid long power cable runs to prevent voltage drops that could affect the brightness uniformity across the LED array.
• Maintenance: Thanks to the SMD architecture, individual LED repair is possible. We advise keeping a "spare parts kit" including extra modules and receiving cards from the same production batch to ensure color matching.
