celexon Battery Motorised Screen 90” Professional Plus Tension Pearlstone

The celexon Motor Professional Plus Batterie Tension - Pearlstone is a modern motorised screen for anyone looking for flexible projection solutions with improved contrast. It combines a contrast-optimised screen fabric with cordless battery operation and an integrated tensioning system for a permanently flat viewing surface.

Modern smart projectors make large images easier than ever before. They focus automatically, correct the image geometry and adapt the projection to the available surface on their own. Instead of being permanently installed in a fixed location, mini, lifestyle and short-throw projectors are used flexibly wherever they are needed – on a sideboard, a side table or a mobile stand.
But this freedom of placement places new demands on the projection surface. Classic matte white screens offer a wide projection angle but often fail to fully exploit the contrast potential of modern projectors in ambient light. Strongly directional ALR fabrics can improve the black level but usually require a precisely defined projector position.
The new Pearlstone contrast fabric closes the gap between these two concepts. It combines a visibly improved black level with uniform, angle-stable image reproduction and was specially developed for the flexible use of modern smart, mini and short-throw projectors.

Contrast reimagined

The Pearlstone fabric takes a different approach from classic ALR projection surfaces. Instead of reflecting the incoming light in a strongly directional way, its specially developed surface ensures even image reproduction across a wide projection and viewing area.
This keeps the projector position flexible. Whether the device is placed centrally, to the side, above or below the screen: brightness, colours and contrast are reproduced evenly across the projection surface. At the same time, viewers in different seating positions benefit from a consistent image without a distracting centre hotspot.
With a viewing angle of 165°, the Pearlstone fabric is also suitable for rooms where several people do not all sit directly in front of the screen. This makes it a versatile solution for the modern living room, flexible media rooms and presentation and training environments.

More image depth in ambient light

The carefully tuned grey tone of the Pearlstone fabric improves the perceived black level compared with classic matte white projection surfaces. Dark areas of the image look richer, gradations are rendered in more detail and the whole image gains visible depth.
This advantage is particularly noticeable in living rooms that cannot be fully darkened. Distracting room reflections are reduced, while colours look natural and balanced. With a gain of 0.9 according to DIN 19045-4, the fabric offers a good balance of image brightness, contrast and colour accuracy.
The Pearlstone screen is therefore not a classic, strongly directional ALR screen. Rather, it is a contrast-optimised projection surface for users who want a better black level without giving up a flexible projector and seating position.

Ultra-fine structures for high-resolution images

The finely textured PVC surface reproduces even small image details precisely and is suitable for high-resolution 4K and 8K content. Contours appear clear, fine textures remain visible and text is displayed cleanly.
The Pearlstone fabric also offers a decisive advantage with modern RGB laser projectors: compared with many classic ALR surfaces, the perceptible speckle or sparkle effect is significantly reduced. The image looks calmer and more natural and remains comfortable to watch even over long periods.
The projection surface thus combines high detail sharpness with uniform brightness, high colour accuracy and a visibly improved black level.

Designed for flexible smart projectors

Autofocus, automatic keystone correction and intelligent image adjustment have long been standard on many smart projectors. For these features to work reliably, the projector must be able to clearly detect the edges of the projection surface.
The black masking border all round of the Pearlstone fabric creates a clear visual frame for this. It helps auto screen fit and similar features detect the visible projection area and position the image correctly within the masking.
Because the Pearlstone fabric reflects the projected light evenly and less directionally than many classic ALR fabrics, the surface is detected reliably even when the projector position varies. This is particularly handy if the projector is not permanently installed but set up again regularly.
At the same time, the black masking improves the perceived image quality: bright content is clearly framed, dark areas of the image appear deeper and the eye has a fixed reference frame.

No time for setting up. Time for content.

Set up the projector, switch it on and let it fit the image automatically: the combination of smart projection technology and Pearlstone fabric makes getting a big picture particularly straightforward. Ideal for anyone who wants to enjoy high-quality projection without spending ages on alignment and image geometry every time.

Permanently tensioned for precise projection

A high-quality surface can only fully show its strengths on a projection surface that is as flat as possible. That is why the Motor Professional Plus battery screen is equipped with a lateral tension system.
The concave cable routing, individually tuned for each screen size, distributes the tensile forces evenly over the entire height of the fabric. Together with the dimensionally stable, rigid large-diameter spiral-groove roller, it ensures excellent flatness and streak-free projection.
The result is a permanently, cleanly tensioned image surface – an important prerequisite for uniform sharpness and precise image geometry.

Motorised – even without a fixed power connection

The combination of Pearlstone fabric and battery technology creates a flexible overall concept for projection and installation. The screen does not need a fixed power connection in everyday use and can therefore also be mounted in positions where there is no socket or prepared power cable.
The integrated, rechargeable 3,000 mAh lithium-ion battery* allows up to 500 extend or retract cycles per charge**. Depending on use, one battery charge can therefore last for up to a year.
The battery is replaceable, contributing to the long-term use of the screen. Should its performance decline after many years of operation, it can be replaced without having to replace the entire screen. This extends the service life and makes this motorised screen a sustainable and reliable long-term solution.
The screen is charged via the charging socket discreetly integrated into the left end cap. The supplied four-metre charging power supply gives you plenty of reach to the nearest socket. An indicator shows the charging status; the screen can also be used while charging.

No Plug. Just Play.

With no permanently visible power cable, the screen blends in particularly discreetly in homes and business premises. At the same time, there is no need for complex electrical work at the installation site. This saves installation effort and opens up new placement options.

Quiet operation and convenient control

The quiet radio-controlled motor extends and retracts the projection surface smoothly. Its soft start and soft stop function reduces speed in the end positions, protects the mechanism and ensures controlled movements.
An RF remote control and a USB wireless trigger are included. The screen can therefore either be operated comfortably from your seat or extended and retracted automatically together with a compatible projector. Manual control directly on the housing is also available.

Flexibly mounted, elegantly integrated

L-shaped mounting brackets integrated at the sides allow classic mounting on a wall or ceiling. Alternatively, the screen can be suspended using the supplied eyelets – for example from high ceilings or trusses.
The discreet, elegant white housing blends unobtrusively into different room concepts. When retracted, the bottom bar closes flush with the housing and protects the projection fabric from external influences.
