Windscreen navigation a reality?

Thin, curved, transparent display panels soon could be attached to vehicle windscreens, providing full navigation information.

Korean company LG Display has unveiled what is claimed to be the world’s first transparent and curved displays.

The company's Head of Electronics and Telecommunications Research explains: 'If thin, transparent and curved display panels could be attached to a windscreen, drivers would be able to see navigation information displayed there.'

But, in order to use the display for windscreens, 2 technologies must be combined - so that the screen becomes both transparent and curved.

The company adds that transparency needs to be improved; the new LG transparent OLED display features a transmittance of 30% - up from 10% of conventional LCD panels. But, to make the panel for car windscreens, the transmittance rate needs to be pushed up to over 60% . . 'This is not simple because most electrodes - small pieces of metal - are opaque. Currently, research is being carried out to find alternative materials such as graphene, which is transparent and conducts electricity'.

There is also a visibility issue over being able to clearly see the information displayed during the day, when it is brighter outside than inside the vehicle. For passengers this is not such a problem - 'shutter' technology can make the background black.

The technology is expected to become commercialised by no later than 2016, with adoption over the next decade. According to research company IHS, the global transparent display market (not just for vehicles . .) will reach $87 (~£51, €65) billion by 2015.
