The floor display is the first point of intersection between the user and the lift. Before the user choses his destination, it informs him about the current location, driving direction or special cases that could cause a delay or prevent the use of the lift such as 'lift in maintenance', priority rides (e.g. bed transport in a hospital) or the case of a fire.


Possibilities of installation for floor displays


Special cases

There can be many situations in which the lift is limited in availability or not available to the user at all. If there is no information available specifying the cause of this, frustration and anger might arise.  

Even though the lift is maintained regularly, technical faults can occur. The cause can be e.g. the failure of a component or vandalism. Common displays will only show the information 'lift out of order'.

flexyPage displays can do more. They are connected to the field bus of the lift. Equipped with a position sensor or load sensor the floor displays can state that there has been a malfunction and show where the lift is currently located and whether there is any persons entrapped (see below under 'Entrappment of persons').

A lift needs to be maintained regularly to be able to ensure safety. For this the technician puts the lift into maintenance mode or for older models turns off the outside control from the halls. This way the lift cannot be used anymore.

Thanks to the connection to the lift, flexyPage displays register the maintenance situation and can directly let the users know - 'Lift in maintenance'.

Everybody knows the sign 'Do not use lift in the event of fire!'. However, this does not inform the user whether or not a fire occurred and how he should behave in such a case. Older displays from the field of digital signage, which have no connection to the lift or the building management, will keep displaying the programmed advertisements.

flexyPage displays know the state of the lift and can - depending on a fire signal - change the layout and inform the user not only about the event of a fire but at the same time show references on how to leave the building or an evacuation plan. A voice announcement can also support this visualisation acoustically.

In normal operation there can also be situations where the lift is available to the user only on a limited basis. This can be e.g. a priority ride or a bed transport in a hospital. If the waiting user is not informed about these circumstances, it will appear as if the lift just rides past him without recognising his request. The user will think that the lift doesn't work well or is faulty and he will be frustrated.

flexyPage displays can show numerous special texts. Many of these are already pre-defined, others can be defined freely. This way the user might not get to his destination faster, but he can see why the lift does not stop for him. This reduces frustration and vandalism.

There can be many reasons for a lift with people inside to stop between two floors. This can be a power interruption (very rare), the failure of a component or the triggering of a safety component. Being entrapped in an elevator is not dangerous, but for many people very unpleasant. Thus, they should be freed as quickly as possible.

In all modern lifts an emergency call system is installed, with which 24 hours a day, 365 days a year an emergency call centre can be reached. They will initiate the release of entrapped persons immediately. Regardless of whether this will be conducted by an external service provider or a lift technician from the building, it is always helpful to know where the lift with the people is currently located.

flexyPage displays offer the possibility to display the position and weight of the cabin in case of a malfunction. For this to work, the sensor data of a position and load sensor is required.

Are the displays connected to the internet, this information can also be provided online.

TFT displays have an important advantage over common LED displays thanks to their high resolution: A lot more information can be displayed in a smaller area. Scrolling of long texts as needed for LED displays is not necessary here. Aditionally, information does not have to be in the form of text. It often looks nicer and is also much more practical and expressive to use distinct symbols.

For lift cars there also has to be an emergency light so that in the case of a power interruption an emergency lighting will still be provided. This can also be achieved through TFT displays, if a white area with maximum brightness is displayed.


Possibilities of installation for displays in the lift cabin


A lift display is of course expected to show the user what the lift is currently doing. The basic information for this is: The current floor, the direction of movement, messages and possibly the current load as well as velocity or position.

With flexyPage displays there are new possibilities of interacting with the passengers of the lift. Requests can still be taken by regular buttons or directly on the display. This way e.g. in case of a hearing diability, information and dialugues can be displayed visually.

Sometimes it is necessary in lifts to add different priorities to calls or to keep the doors open longer for loading. When for example a patient in a hospital is being transportet to surgery, the ride should be direct and should not be interrupted at every floor in between. For this case the lift can be given a priority signal through an external input signal via RFID-Chip, PIN code or via timer/events.

flexyPage displays have an inegrated voice announcement. This supports the display in indicating the floor level and can be very useful especially for people with a seeing disability or when the cabin is very full and the view of the display compromised. Additionally important notifications can be given (Mind the step / Door closing) and background music can be played for entertainment. The sound can be played by an internal loudspeaker or external active speakers in stereo. Any number of files can be saved on the SD card of the display. The volume of the background music will be reduced by a fading function during voice announcements.

We integrated various functions for recognising dangerous sotuations into the display. For example the detection of steps created by a wrong position of the lift cabin. For this function the data of an absolute position sensor has to be available via the CANopen-Lift interface.

Then the displays will measure how accurately the cabin stops every time and can automatically display an appropriate warning when the door opens. At the same time the voice announcement can promt a 'mind the step' warning.

flexyPage displays are equipped with modern processors usually used for phones and tablets. For these battery-driven devices they achieve a high processing power with minimal energy consumption. For the background lighting of the displays we only use modern LED backlights, which also have a very high efficiency.

To reduce the energy consumption even further, we implemented many functions that let us recognise whether there is a person in the lift or not and whether the lift is currently in use or rest. In resting periods the backlights can be reduced or fully switched off, thus, reducing the energy demand to a minimum. When the display is needed again, the backlight can be turned back on in the fraction of a second.

Several displays in one lift with and without touch

Often, in a project, several displays have to work as a group. In this case it is important that the displays can be linked together and the information of the sensors and of the building can be shared among all displays. A parallel wiring to every single display requires too much effort and limits the amount of possible signals.



The flexyPage displays are always equipped with a LAN-port. Via this port the configuration of the displays, as well as the connection to the internet and to the building automation is realised. In the displays, equipped with the display controller fel1A (starting at 10,1"), there are two 10/100 Mbit LAN-ports, which are coupled via an internal switch. This way, many displays can be connected as a chain very easily without the necessity of any further active external network components (switch/hub). This saves enormous costs in planning and realization of connected display systems.


Furthermore, the flexyPage displays include a CANopen-interface to connect to lifts, to query sensors and to communicate with each other.

If the displays are deployed in a lift that already supports the CANopen standard, complete information about the lift is available without extensive wiring. But even in older lifts this port offers many advantages. Here all displays can be connected to the bus wire very easily and the connection to the control can occur via a single I/O module for all signals. It is even possible to use the market-common sensors independently from the control.

With the CAN bus it is possible to transmit real-time-capable messages. This makes it ideally suited to synchronize various processes in various displays, for example, for the reproduction of multimedia data on several displays.


We implented a CAN / LAN gateway into the flexyPage displays and can therefore tunnel the data from CAN networks through an intranet or the internet.

This simplifies the mounting. In many situations it is possible to use existing installations and less cable has to be wired. The detailed distance diagnosis up to the field bus level or the connection to other elements of the building automation is easily possible as well.



cross-linking several displays in a lift

All flexyPage displays support the open standard CANopen-Lift. If the lift control supports the standard as well, the installation and setup is simple. This is due to the plug and play abilities of the standard. In this case the complete information of the lift is available to the display. If the lift possesses an old discrete control system or a proprietary bus system the flexyPage displays can be used as well. In this case the necessary signals can be provided with the help of an I/O-module. Additionally, sensors can be connected to the display that enable supplement functions, which are usually limited to modern lifts with CANopen controllers.

Lift with CANopen

The connection to a lift with the CANopen-Lift standard is very easy. Nonetheless the installation has to be made by a specialist, who is familiar with the security requirements for the work at electric contstructions of lifts.

Every flexyPage display comes with a CAN-bus interface. The interface terminals have to be connected with the bus of the construction using only two twisted wires. The standard sets the wire colors of white for CAN H and blue for CAN L. Next, the termination of the CAN-bus has to be checked and possibly adjusted.

After the login into the user interface of the flexyPage display the NodeID and the baud rate have to be set up. Now all messages on the bus of the lift are available for the display as well. You can now use the widgets you need for your application.

Lift without CANopen

For lifts that do not support CANopen-Lift the necessary signals can be provided by an external I/O-module. The I/O-module can be intergrated directly at the signals' origin, for example, in the cabinet of the control or in the terminal. For data connection to the display only 2 twisted wires are necessary. The I/O-modules are available from different manufacturers freely on the market.

Additional Shaft Installation

If, in the course of modernisation, LED displays on the floors are to be retrofitted, the whole shaft installation can occur via a CANopen-installation controlled by a flexyPage display. This way the wiring in the shaft necessitates only two twisted wires and besides the exterior calls it is possible to output floor status, run direction, departing arrows, floor bell and special texts.

Additional Sensors

If additional sensors are needed, which cannot be provided by the existing control, the necessary sensors can be connected directly to the CAN-bus. This way, it is possible to show, for example, the current weight or the position and speed in the cabin.
