摘要： A transparent thin film display element (100) with a display region(101), and a transition region (105) having a first edge (106) bordering the display region and a second edge (107) opposite to the first edge, the transparent display element having a layer stack (103) comprises:a first conductor layer (110); a second conductor layer (120); and an emissive layer (130) superposed between the first and the second conductor layers and configured to emit light upon electrical current flowing through the emissive layer between the first and the second conductor layers. At least one layer (120) of a group comprising the first and the second conductor layers and the emissive layer has, in the transition region (105), a first coverage at the first edge (106), a second coverage lower than the first coverage at the second edge (107), and an intermediate coverage lying between the first and the second coverage.

摘要： This specification relates to a display arrangement (1) comprising a thin film display element (100) and a display driver unit (200) configured to, while maintaining a second display terminal (222) associated with a second display electrode (122) in its high-impedance state, set a first display terminal (221) associated with a first display electrode (121) and a common display terminal (211) associated with a common display electrode (111), which at least partly laterally overlaps the first display electrode (121) and the second play electrode (122), to their first states and, after setting the first display terminal (221) and the common display terminal (211) to their first states, set the second display terminal (222) to its first state, while maintaining the first display terminal (221) and the common display terminal (211) in their high-impedance states, such that electrical current passes between the first display electrode (121) and the second display electrode (122).

摘要： A method for manufacturing an inorganic thin film electroluminescent display element comprises forming a layer structure, said forming the layer structure comprising forming a first dielectric layer (11); forming a luminescent layer (12), comprising manganese doped zinc sulfide ZnS:Mn, on the first dielectric layer, and forming a second dielectric layer (13) on the luminescent layer. Each of the first and the second dielectric layers are formed so as to comprise nanolaminate with alternating aluminum oxide Al2O3 and zirconium oxide ZrO2 sub-layers.
