  • the invention relates to a display element for a motor vehicle for displaying at least one symbol provided by means of hole laser technology.
  • the display element has a base member having a first side and a first side opposite the second side, wherein in the base member a plurality of holes from the first side to the second side of the base member by means of hole laser technique is introduced and wherein the holes are filled with a filling which comprises an at least partially translucent filling material.
  • the invention relates to a display device with such a display element, a motor vehicle with such a display device and a method for producing such a display element.
  • DE 20 2008 018 130 U1 describes an assembly with a light-emitting device, in particular an LED, which is provided by applying a silicone gel or an epoxy resin to an LED chip in order to increase the efficiency or the efficiency. Through the silicone gel or the epoxy resin while a lens mold is produced, on the surface of a phosphor layer is applied.
  • the display element according to the invention for a motor vehicle is characterized in that the filling has a first part which protrudes from the respective holes on a first side of the base element.
  • the filling thus does not close flush with the hole openings, but protrudes beyond them.
  • the first part of the filling is formed by a dome with a convex surface.
  • a convex-shaped surface allows particularly broad viewing angles and, moreover, such a display element is particularly easy to produce, since, for example, with a suitable choice of filling material, which can be filled in a viscous state in the holes and then cured, such a convex surface shape automatically due to Surface tension of the viscous filling material results.
  • the filling material is a light-scattering filling material. This is particularly advantageous since even wider beam angles can be achieved by light-scattering properties of the filling material.
  • the filling material may be, for example, a plastic and / or a resin. These materials are particularly inexpensive and can be easily formed with very high light-scattering properties.
  • the invention relates to a display device with a display element according to the invention, wherein the display device further comprises at least one light source.
  • the light source is arranged below the base element with a distance of the second side of the base element, wherein the second side of the base element defines a bottom.
  • only a single light source, such as an LED, or even more such light sources for illuminating the filled holes be provided of the display element. If the display element is illuminated by the at least one light source, the light emitted by the light source is guided through the holes filled with the filling in the base element and through the first part of the filling which projects beyond the base element and preferably a convexly shaped surface provides advantageously radiated in very wide radiation angles.

  • the display element 10 displays a symbol 12, which is shown here as an example as A.
  • This symbol 12 is formed by a multiplicity of holes introduced into a base element 14 by means of a hole laser technique, with only one hole 16 being provided with a reference numeral for reasons of clarity.
  • the symbol 12 is thereby generated in particular by the holes 16 in that the holes 16 are thereby introduced into the basic element within the symbol contour 12a and fill the regions of the symbol 12 lying within the symbol contour 12a.
  • the production of symbols to be illuminated by means of hole laser technology has the advantage that closed interior areas of symbols, such as so-called closed punches in letters, can also be provided without required webs.

  • the holes 16 are filled with a filling 18 such that a first part of the filling 18a protrudes beyond the base member 14.
  • the material outlet that is to say the first part 18a of the filling 18, thereby produces a dome with a convex surface, whereby a particularly good light scattering or light emission with large emission angles is effected.
  • the laser holes 16 may be filled with plastic or resin, for example.
  • the filling is designed so that it has good light scattering properties. This can be provided in a simple manner by scattering particles in the material or production of crystals in the corresponding material. By using a light-scattering material, the exit angle of the light from the dome 18a can be additionally increased.
  • the display device 20 has a light source 22, which is arranged below the display element 10, that is to say on the side of the display element 10 facing away from the domes.
  • a backlight of the display element 10 is provided.
  • the backlight can also include other light sources 22.
  • the light emitted by the light source 22 is passed through the filling 18 and exits the dome, thereby generating the luminous symbol 12. Due to the protruding parts 18a of the filling material 18 and the scattering properties of the filling material 18, the light is coupled out of the domes at a very large opening angle.
