Definitions

  • the invention relates to edge resistant windows in general and displays in particular.
  • the invention relates to viewing windows, which are constructed from laminates of the same or different materials.
  • vision windows made of laminates is in the field of displays, both for stationary devices such as televisions or screens and for mobile devices such as telephones, tablets, laptops, watches and the like. Especially with mobile devices is important that the displays are robust against breaking and scratching, especially when it comes to touch displays, ie those that can be controlled by finger movements on the screen / display.
  • the use of crystalline materials as the topmost laminate layer makes use of the good thermal, chemical and especially mechanical properties of ceramic materials.
  • these materials also have disadvantages, which are in particular due to their crystallinity. If force is exerted selectively on a ceramic, ceramics react even at comparatively low forces with breakage, since they are brittle. Thus, if a dynamic punctiform load is exerted on laminate viewing windows, for example if, for example, a mobile telephone falls on one of its edges or, in particular, one of its corners, the probability of failure of the viewing window due to breaks or cracks is greatest.
  • the object of the invention is therefore to provide a viewing window made of a laminate with a crystalline layer and a high breaking strength.
  • the object is achieved by a viewing window with the features of the invention.
  • the viewing window according to the invention comprises a laminate of identical or different materials, of which at least one layer consists of or at least comprises a crystalline ceramic material or a brittle-hard material.
  • crystalline ceramic materials includes both monocrystalline and polycrystalline materials such as sapphire and transparent polycrystalline ceramics such as Al 2 O 3, spinel, AION ceramics, ceramics from the system Y-Al-O such as YAG.
  • a brittle-hard material is understood in particular to be glasses.
  • the viewing window comprises a laminate of at least one layer of a less brittle material and at least one layer of a crystalline ceramic material or a brittle-hard material, wherein the layers are preferably interconnected via an adhesive layer. All layers, including the composite layer of adhesive, are optically transparent, ie have a RIT (Real Inline Transmission) of more than 70% in the visible range of the wavelength spectrum.
  • RIT Real Inline Transmission
  • the laminate is stacked on top of each other so that around the layer of ceramic material or the spherically hard material, a preferably mutually projecting edge of at least one of the other layers is formed.
  • a narrow adhesive edge is wrapped around the edges of the layer of ceramic material or the sprodharten material, so that occurring dynamic loads, for example, in an impact of the component can be initially absorbed by the adhesive edge.
  • the adhesive edge thus serves at the vulnerable edges of the viewing window and in particular the layer of ceramic material or a sprodharten material as a damping element.
  • the material of the adhesive edge and / or of the composite material adhesive has the same refractive index (deviation of max +/- 0.01, better 0.002) as the layer of ceramic material or the spud-hard material. This leads to the fact that the adhesive edge is not visible and visually creates a uniform surface.
  • the adhesive is precisely metered ⁇ -precise or parts of ⁇ and applied so that when selectively pressing the adjacent layer, the layer of ceramic material or the sprodharten material and the adhesive, just as much glue on the edges is pressed out that this edge is created.
  • the targeted pressing of the layers essentially comprises the adaptation of the contact pressure to the adhesive viscosity and area.
  • the present invention relates to:
  • - Viewing window comprising a laminate of the same or different materials, of which at least one layer comprises a crystalline ceramic material or a spherically hard material.
  • the crystalline ceramic material is a transparent monocrystalline or a transparent polycrystalline material.
  • Viewing window wherein the transparent monocrystalline material is sapphire.
  • Viewing window, wherein the transparent polycrystalline ceramic is selected from the material group consisting of Al2O3, spinel, AION or YAG.
  • the viewing window is a laminate of at least one layer of a less brittle material and at least one layer of a crystalline ceramic material or a brittle-hard material, wherein the layers are connected to one another via an adhesive layer.
  • the material of the adhesive edge has the same refractive index as the layer of ceramic material or the brittle-hard material.
