The liquid crystals are aligned together with embedded color particles by an alternating voltage in such a way that the screen darkens or brightens. This happens within milliseconds. According to Continental, in transparent mode the windows no longer show any visible residual turbidity. In addition, different color schemes can be realized.
Controlled darkening of individual window panes offers more: More privacy protection and better air conditioning due to less heating of the interior. If the tinting function in the windshield is coupled with the vehicle electrical system and the cloud connection, areas of the windshield can be automatically darkened or brightened in good time depending on the weather conditions and the position of the sun. As a further example of application, the windows, networked with the locking system, could defrost immediately in winter when the driver approaches his car.
The intelligent glass could become even more important in a completely different function: Information from the driver assistance and infotainment systems could be displayed on a smart glass pane. The pane could also be turned into a smart display with touchscreen elements, according to the technology supplier's pioneers.
