Patent number: 11504944Abstract: A cover window for a display includes a multilayer polymer film. The multilayer polymer film includes a first transparent, colorless polymer layer having a first elastic modulus and a second transparent, colorless polymer layer having a second elastic modulus. Each of the first and second transparent, colorless polymer layers include a polyimide, a polyamide imide, or a block copolymer of a polyimide. The polymers of both the first and second transparent, colorless polymer layers are cross-linked. The first elastic modulus is different from the second elastic modulus. The first and second transparent, colorless polymer layers are bonded by consolidation and cross-linking. The first transparent, colorless layer of the multilayer polymer film is the layer farthest from the display.Type: GrantFiled: November 5, 2021Date of Patent: November 22, 2022Assignee: DUPONT ELECTRONICS, INC.Inventors: Kostantinos Kourtakis, Gene M Rossi, Leopoldo Alejandro Carbajal, Mark Allan Lamontia, Mobin Yahyazadehfar

Publication number: 20200128627Abstract: Heater design plays an important role in determining the stretchability of a heater and this invention provides several configurations that improve stretchability. In some of these configurations the use of bus bars with wavelike form, an undulating conductor, provides good stretchability in all directions. In some configurations, slits can be cut in the substrate to further accommodate stretching and improve breathability.Type: ApplicationFiled: October 22, 2018Publication date: April 23, 2020Inventors: MARK ALLAN LAMONTIA, MEHRDAD MEHDIZADEH, MOBIN YAHYAZADEHFAR
