Definitions

  • the invention relates to a glass keyboard and its use.
  • Such transparent pressure switch elements also known as touch panels
  • touch panels are known and are nowadays widely used as input media in the form of an attachment module in front of flat screens or television screens.
  • touch panels can also be used as a control terminal instead of a classic keyboard without a combination with a flat screen or television screen.
  • the different touch panels have different user interfaces.
  • Touch panels based on capacitive operating principles have a mechanically non-compliant glass surface during operation. The principle of operation is based on the fact that, due to the different dielectric properties of the finger or the auxiliary tool compared to the air, a change in capacitance is formed around the point of contact. The disadvantage here is that contamination around the point of contact can also be mistakenly interpreted as touch.
  • capacitive displays have a high mechanical, physical and chemical resistance. Capacitive displays are therefore used, for example, in communication terminals in banks, information terminals or the like. used.
  • Ultrasonic touch panels, infrared touch panels and field effect touch panels are based on comparable optical or electrical principles.
  • the surface can be made of glass. Contamination is also critical here, so that such designs are aimed at similar areas of application as capacitive panels. However, their market share is much smaller than the capacitive panels.
  • Resistive touch panels are based on spacing a conductively coated flat carrier, the base material of which is made of glass or plastic panes a few millimeters thick, with a thin, deformable film that is also conductively coated. When the film is touched, its deformation leads to local contacting of the two opposite conductive layers. In principle there are two versions of resistive touch panels:
  • the conductive layers have a very homogeneous, locally constant surface resistance. By reading out the electrical voltage values, the location of the contact can be inferred due to the homogeneous surface resistance.
  • the conductive layers of carrier and film are structured so that discrete conductor tracks are created. Touching the touch panel creates a local short circuit between the discrete conductor tracks, which means that the contact location can be inferred within the framework of the structure size of the conductor tracks.
  • Transparent plastics are used as the film material in the touch panels currently predominantly available on the market. These are kept at a distance from the carrier material by means of spacers, so that incorrect switching (touching the conductive layers) without actuation is excluded.
  • one advantage of resistive touch panels is that a mechanical, albeit low, mechanical deformation force has to be exerted on the film for actuation. Therefore, their sensitivity to contamination is significantly lower, which is why almost exclusively resistive touch panels are used in safety-relevant areas such as medical technology and industrial automation.
  • plastics as film material
  • the physical and chemical resistance is significantly lower than that of glass user interfaces.
  • the transparency may deteriorate.
  • the surface sterilizability is restricted.
  • Another disadvantage when using plastics is the lower thermal resistance (softening, swelling) and the strong thermal expansions compared to glass.
  • the size of the touch panels is severely restricted due to the swellings of the plastics.
  • Such phenomena in relatively small resistive touch panels, such as those used in electronic appointment planners are relatively simple and therefore inexpensive to control. Novel designs of resistive touch panels are being used to use a thin glass pane as the film, which has sufficient deformability at a thickness of 0.15 mm to 0.4 mm.
  • Such a surface has the advantages of the chemical and physical resistance of glass with little risk of incorrect switching.
  • EP 0 546 003 B1 discloses a pressure switch element formed from a glass laminate, which is formed from a flexible thin glass pane and at least one carrier material pane, each of which has an electrically conductive layer on the mutually facing surfaces.
  • the opposing electrically conductive layers are kept at a distance using a spacer.
  • the electrically conductive layers touch one another at the essentially point-specific pressure load point.
  • a pressure switch element of comparable construction is known from US 4,901,074.
  • the thick carrier material disc is connected to the flexible thin glass disc in the edge region, for example with a UV-curing adhesive.
  • a UV-curing adhesive There is adhesive between the two glass panes in the edge area.
  • a critical property when using thin glass panes compared to the use of plastics is the increased sensitivity to breakage (brittleness) when using the keyboard, especially in the edge area. Essentially two break phenomena occur here:
  • a keyboard operation in the edge area of the thin glass pane leads to mechanical tensile stress in the edge area of the thin glass. Due to micro cracks in the course of the edge, which are unavoidable with conventional cutting processes, this can lead to breakage of the edge.
  • the glass keyboard should optionally have effective edge protection, in particular the thin glass pane.

  • the breaking strength of the glass keyboard is significantly increased.
  • the tensile stresses and bends of the thin glass pane that occur particularly in the area of the mount during pressure loading are minimized by deforming the mount in the flexible area.

  • the surface of the thin glass pane is subjected to a substantial pressure load and the lower surface of the thin glass pane is subjected to a tensile load, at least in the area of the holder, of the flexible thin glass pane, the restoring moment essentially resulting from the deformation of the thin glass pane.
  • the thin glass pane has a shape that is curved inwards toward the carrier material pane, at least in the area of the holder, when subjected to pressure. This ensures a particularly high breaking strength when the flexible thin glass pane is loaded in the edge area of the glass keyboard.
