Patent number: 10775671Abstract: A display device includes a light emitter comprising a set of light emitter portions, wherein at least one light emitter portion of the set is configured to emit light with an excitation wavelength, and a color conversion layer including a set of conversion layer portions. At least one conversion layer portion of the set comprises a film comprising a solid polymer composition that includes luminescent crystals of perovskite structure, which are selected from compounds of formula (I): M1aM2bXc (I), wherein M1 represents Cs, M2 represents Pb, and X independently represents anions selected from the group consisting of Cl, Br, I, cyanide, and thiocyanate. The luminescent crystals are of size between 3 nm and 3000 nm, and emit light of a wavelength in response to excitation by the light emitted by at least one corresponding light emitter portion of the set, wherein the excitation wavelength is shorter than the wavelength.Type: GrantFiled: December 21, 2016Date of Patent: September 15, 2020Assignee: AVANTAMA AGInventors: Norman Lüchinger, Ines Weber, Stefan Loher, Marek Oszajca, Benjamin Hartmeier

Patent number: 10294420Abstract: A luminescent component comprises a first film comprising a first solid polymer composition and a second film comprising a second solid polymer composition. The first solid polymer composition comprises first luminescent crystals. The second solid polymer composition comprises second luminescent crystals. The first luminescent crystals are of size between 3 nm and 3000 nm, and emit red light in response to excitation by light with a shorter wavelength. The second luminescent crystals are of size between 3 nm and 3000 nm, and emit green light in response to excitation by light with a shorter wavelength. Said luminescent component is particularly suited for the application in LCD-backlight color conversion.Type: GrantFiled: December 15, 2016Date of Patent: May 21, 2019Assignee: AVANTAMA AGInventors: Norman Albert Luchinger, Ines Weber, Stefan Loher, Marek Oszajca, Benjamin Hartmeier
