Abstract (en)
[origin: WO2005024136A1] A dynamic road marking unit is capable of switching between a first and a second display state. It has an electro-optical layer which is bistable. In principle the dynamic road marking unit only requires energy when switching between the states, i.e. when the visual properties of the dynamic road marking unit are changed.
