Definitions

  • the invention relates to a lighting and display film according to the preamble of claim 1 and a user interface according to the preamble of claim 2.
  • a user interface essentially consists of a keyboard and a display, for example a single or multi-cell LC display.
  • the keyboard can also be integrated in a so-called touchscreen as a display device.
  • the touchscreen has a touch-sensitive surface, via which the relevant functions, characters or numbers can be activated by pressing on defined display fields.
  • Such a touchscreen is comparatively expensive, susceptible to dirt and very susceptible to shocks such as bumps or blows.
  • PEL foils phosphor electroluminescence
  • AMEL foils active matrix electro-luminescence
  • Such films are sold, for example, by the Planar company (Planar homepage: http://www.planar.com/tofc.htm). These foils are used for lighting purposes in civil and military areas.
  • the film can be used for backlighting user interfaces or displays.
  • membrane keyboards simple, mostly icon-based user interfaces can be implemented. These are used, for example, in seat control in aircraft.
  • the electroluminescent film offers a high resolution, so that, for example, the display of numbers with seven segments or the display of letters with 14 segments is possible. However, the high resolution requires the embedding of control modules in the film, so that their production becomes comparatively expensive.
  • the invention is based on the object of specifying a lighting and display film which is suitable for a user interface and which enables a display of characters with little effort for controlling the segments.
  • the user interface realized using the lighting and display film can be designed in such a way that neither dirt nor moisture can penetrate into the corresponding device via the user interface.
  • the user interface is easier to install in a housing. Furthermore, fewer parts have to be used and there are fewer problems with manufacturing tolerances.
  • FIG. 3 shows a section of a display device with character segments
  • FIG. 4 shows a section through a character segment.
  • FIG. 1 shows a top view of a user interface BOF which, for example, has a keyboard field TF on the left and a display device AE on the right.
  • a user interface BOF can be used in communication terminals, such as telephones, fax machines or similar devices.
  • the keyboard field TF contains the twelve-key block known from telephony, the keys not being individually identified.
  • the display device AE has numerical fields ZF1 to ZF6, which are arranged in two rows.
  • a field with 7 segments is drawn. With such a number field, numbers are preferably represented.
  • Fields with, for example, 14 segments can also be used in the invention, by means of which both numbers and letters can be represented.
  • the number of characters that can be displayed in one line and the number of lines can also be freely selected within wide limits.
  • FIG. 2 shows a cross-section of an illumination and display film BAF through which the user interface BOF shown in FIG. 1 is realized.
  • the lighting and display film BAF has color fields FF in a first row, which points to a user (not shown), and light fields LF in a second row.
  • a color field FF and the underlying light field LF are each assigned to one of the keys of the key field TF or a number field ZF1 to ZF6 of the display device AE. Seen from the operator's side is below the Color fields FF or light fields LF for the keyboard field TF a membrane keyboard FT arranged.
  • the corresponding key of the membrane keyboard FT which is not shown in more detail, can be activated by pressing one of the keys of the keypad TF.
  • the individual keys of the keyboard field TF and the individual segments of the number fields ZF1 to ZF6 of the display device AE are illuminated with the light fields LF.
  • the color fields FF which are also assigned to these individual elements, different colors can be selected for them.
  • the color fields FF can also be absent, so that both the keys and the fields of the display device AE are then illuminated in a single color.
  • Electroluminescent films for example the PEL or AMEL films cited at the beginning, are preferably used for the illumination. In particular, those for lighting the individual keys of the keyboard field TF are provided
  • the light fields LF used for the display or illumination of characters do not require the high resolution of the AMEL film that is possible in principle.
  • the number field ZF1 of the display device AE is shown enlarged in FIG.
  • the numerical field ZF1 has 7 light segments LSI to LS7.
  • 14 segments or light segments can also be provided for the character display.
  • the light segments LSI to LS7 are connected to a common reference potential BP.
  • connecting lines ALI to AL6 are provided (the missing connecting line AL7 will be discussed with reference to FIG. 4).
  • the light segments LSI to LS7 and the reference potential BP and the connecting lines ALI to AL6 are arranged in one plane (E1, see FIG. 4). For this purpose, for example, they are embedded in a plane of an electroluminescent film, by means of which the BAF lighting and display film is realized.
  • FIG. 4 shows a section S (see FIG. 3) through the numerical field ZF1 at the level of the three middle, superimposed light segments.
  • voltages for the control of the individual light segments LS 1 to LS7, voltages of approximately 100 volts are required, so that the connecting lines AS1 to AS6 cannot be arranged as tightly as desired.
  • the light segments LSI to LS7 (shown in FIG. 3) and the connecting lines ALI to AL6 and the reference potential BP are arranged in one plane E1.
  • the lighting and display film BAF has a further level E2, in which the connecting line AL7 is embedded.
  • the connecting line AL7 is used to control the middle light segment.
  • This light segment (not shown in the figure) is due to the size of the light segments themselves, i.e. Due to the small distances between the light segments and the necessary distance between the connecting lines ALI to AL6 and BP at the voltage used, not reachable in the plane El.
  • connection lines in level E2 may be necessary for the corresponding activation of the internal light segments in a character field (corresponds to the numerical field ZF, but serves to represent characters, i.e. letters and numbers). Further levels can also be provided for this purpose.

Abstract

L'invention concerne un film d'éclairage et d'affichage (BAF) muni de champs caractères contenant des segments lumineux (LS1 à LS7), servant à représenter des caractères. Des segments lumineux (LS1 à LS6) et les lignes de connexion (AL1 à AL6, BP) associées sont placés en un plan (E1) dans le film (BAF). Selon l'invention, il est prévu au moins un autre plan (E2) avec des lignes de connexion (AL7).
