Patent number: 11137639Abstract: The invention relates to a switchable optical device (10) having a layer structure comprising at least one switchable layer (15) and at least one optical layer (20, 22). The at least one switchable layer (15) comprises a liquid-crystalline material and at least one dye. The at least one optical layer (20, 22) has at least one reflection band (32) which includes at least a first part of the visible spectrum and has at least one transmission band (30, 34) which includes at least a second part of the visible spectrum. The absorption spectrum of the at least one switchable layer (15) is adjusted by means of the at least one dye such that the light transmission through the switchable optical device (10) for incident light in the visible light spectrum for at least one of the states of the switchable layer (15) is set to a predetermined transmission spectrum.Type: GrantFiled: May 8, 2018Date of Patent: October 5, 2021Assignee: MERCK PATENT GMBHInventors: Ties De Jong, Casper Van Oosten
