Turn your smartphone into a mobile workstation
The Fieldbook LD140 is a ruggedized 14″ lapdock designed for field professionals who need to work comfortably, for long periods of time, and safely, without having to carry multiple pieces of computer equipment.
The concept is simple and rational:
the smartphone remains the sole smart device (applications, data, identity),
the LD140 provides the ergonomics, display, connectivity, and robustness of a real workstation.
A concept designed for the field
In the field, smartphones are essential for quick communication and consultation. But as soon as usage becomes more demanding—writing, typing, checking, prolonged consultation, videoconferencing — their limitations become apparent.
The Fieldbook LD140 bridges this gap by transforming the smartphone into a mobile workstation that is immediately usable, comfortable, and suited to professional environments.
Maximum security, by design
No data. No password. No risk. The LD140 contains:
- no storage memory,
- no identifiers,
- no passwords,
- nor autonomous system.
When disconnected from the smartphone, it does not retain any information whatsoever.
In the event of loss, theft, or abandonment of equipment in a vehicle, workshop, or on a construction site, no data is compromised — because it is not stored in the lapdock. Security is built in by design, without relying on complex procedures or user behavior.
An economical alternative to rugged laptops
Why finance, maintain, and secure a complete rugged laptop when:
- Smartphones already have the performance necessary for most professional uses.
- business applications are already deployed,
- the user environment is already secure and under control
With the LD140, you only invest in what smartphones lack in the field:
- a large, easy-to-read screen,
- sustainable workplace ergonomics,
- a complete set of connectors,
- a rugged design.
Result: fewer devices, less administration, lower costs, and optimized TCO across the entire fleet.
Zero configuration, immediate use
The Fieldbook LD140 is ready to use.
- No preparation phase
- No individual configuration
- No environment to install
As soon as an Android smartphone compatible with desktop mode is connected, the user instantly finds their work environment.
(Compatible with major Android desktop modes, including Samsung DeX, without dependence on a single manufacturer.)
Multi-user, naturally
The LD140 is perfectly suited for shared use: workshops, mobile teams, vehicles, preparation or maintenance areas.
A user plugs in their smartphone → they work.
They disconnect → the device returns to neutral.
Another user plugs in theirs → new immediate environment.
No local session, no data to delete, no intermediate manipulation.
Comfortable working conditions, even in difficult conditions
• Integrated audio and camera with privacy shutter
• Ergonomics adapted for extended use in the field
Autonomy designed for professional use
The LD140 incorporates a battery that allows:
- to operate the lapdock without an external power supply,
- to recharge the smartphone if necessary.
The battery can be removed with a simple movement. It is possible to extend the battery life by replacing the battery pack without interrupting activity.
An external battery charger (4 slots) is available as an option to keep batteries continuously charged and ensure extended use in the field.
Full connectivity
The Fieldbook LD140 offers connectivity suited to professional use:
- 3 USB Type-A ports for connecting any compatible device
- RJ45 network port for environments without Wi-Fi or with limited connectivity
- HDMI port to extend or duplicate the display on an external monitor
Built to last
• IP65 certification
• Resistant to shocks, vibrations, drops, and scratches
• Suitable for use in workshops, warehouses, vehicles, and construction sites
Available accessories
To adapt to all contexts of use:
- smartphone and tablet holders,
- vehicle mounts,
- vehicle power supplies,
- external battery charger (4 slots).
In summary
👉 The Fieldbook LD140 is not just another computer.
It is a new approach to the mobile workstation: simpler, safer, and more efficient, built around the smartphone already in use.
