ELECTRONIC MIRROR

An electronic mirror (24) comprises a liquid crystal cell (30), wherein the liquid crystal cell (30) comprises a first transparent electrode (34a), a second transparent electrode (34b), a liquid crystal layer (36) comprising liquid crystal molecules arranged between the first transparent electrode (34a) and the second transparent electrode (34b), and an AC voltage source (50) configured to apply an alternating voltage across the liquid crystal layer (36) between the first transparent electrode (34a) and the second transparent electrode (34b), wherein, when a voltage is applied across the liquid crystal layer (36), the liquid crystal molecules in the liquid crystal layer (36) change their orientation, and the electronic mirror (24) is configured to apply a varying voltage across the liquid crystal layer (36) which gradually decreases from outer areas towards the center of the liquid crystal layer (36) such that the refraction index of the liquid crystal layer (36) gradually varies from outer areas towards the center of the liquid crystal layer (36). The liquid crystal cell further comprises a polarizing filter layer (32b), wherein the second transparent electrode (34b) is arranged between the polarizing filter layer (32b) and the liquid crystal layer (36), and a reflective polarizing filter layer (32a), wherein the first transparent electrode (34a) is arranged between the reflective polarizing filter layer (32a) and the liquid crystal layer (36).
