A European consortium is developing innovative unbreakable displays

EU-funded research looks for extra-unbreakable displays

German-led consortium has launched a project developing extremely robust and very lightweight displays for smart phones and advertising.

The LiCRA project, expected to last 30 months, will look into innovative ways to build flexible and highly ruggedised displays based on liquid crystals deposited on plastic substrates.

The team believes they will be able to develop methodology to build displays with better resolution at lower production costs than offered by currently existing methods.

University of Stuttgart, coordinating the project, will work with a British company Plastic Logic to advance its knowledge of the organic thin film transistor (OTFT) technology, which has, so far, been used for monochrome e-paper displays.

The team will devise innovative processes for liquid crystal cells assembly and look into possibilities to use organic light emitting diodes (OLEDs) with polarized light emission.

The use of OLEDs would enable reducing the backlight demands and removing one of the two polariser sheets, which have so far been necessary for liquid crystal cells.

LOFO High Tech Film will develop plastic films for the liquid crystal displays with special attention to low deformation during the successive production of the liquid crystal displays as well as minimised optical birefringence as both would degrade the optical performance of the displays.

Micro resist technology GmbH will develop materials and processes for nano-imprint lithography. While the production if microelectronic structures with classic lithography means exposure of a photo resist with UV light and subsequent development of the resist, in nano imprint lithography the desired structures are directly transferred to an adequate nano imprint resist by the use of a mould.

The unbreakable, light-weight and low-cost displays could be used in consumer electronics including tablets and smartphones, in the automotive sector or advertising.
