Projektbeschreibung / Description
The project is aimed to demonstrate the use of printed electroluminescent displays (ELD) in real world applications. It is a further step in the work of Landshut UAS on developing printed matrix ELDs with compact low cost driver electronics. The functional principle and integration of such display systems in smart textile articles can be found in  and  respectively.
Demonstrators of January 2018 (created for LOPEC 2018)
Demonstrators created in January 2018 feature an ELD integrated into a bag and a back pack with the primary goal to allow traffic signalling for cyclists or skaters during the dark periods of day. In this mode light signals for turning and braking will be given by the display to inform the vehicles driving behind the sportsman of her or his manoeuvres. The second mode of operation – the “fun mode” – can be used to show short text messages to surrounding persons, e.g. during social events or in everyday life , . The idea for this mode originates from our experience with the previous demonstrators  where we observed that young people found it “cool” to be able to “post” their “status” for everyone as it happens in social networks. In the both modes the display will be controlled wirelessly (via Bluetooth) using either a smartphone or a dedicated device.
The major goal of the demonstrator project is to reveal applications which are possible with currently available materials and technology and which can be implemented with low costs even in a low volume production. It will be used at Landshut UAS as a platform for further testing of the use cases and technology under the real life conditions.
The main part of the demonstrators is an electroluminescent matrix display printed on a flexible PET substrate and packaged together with its driver electronics to form a “foil display”. This foil display is designed as a self-contained component to allow an easy integration into textile articles. In the demonstrator the integration is implemented by sliding the foil display into a dedicated pocket on the bag. So it can be easily removed if washing is needed. Several display topologies and matrix resolutions will be tested during the project; focus will lie on a display with a matrix of 32 by 5 pixels and with six to nine additional pictogram elements.
