Definitions

  • This invention is concerned with improvements in or relating to key pads, and in particular, though not exclusively, to a key pad having one or more keys having a variable visual appearance in accordance with varying light conditions .
  • a key pad according to the invention may be used for display of information on a permanent or intermittent basis.
  • information is required for display only on an intermittent basis it is considered advantageous if the presence of information graphics is not visible to an observer until the information becomes relevant to a particular situation and is to be displayed.
  • a key pad having one or more keys, the or at least one of the keys having an obverse side and a reverse side, and wherein, in use, when viewed from the obverse side the or the at least one of the keys has a first appearance when not lit from the reverse side, but has a second appearance when lit from the reverse side.
  • a key pad having one or more keys, wherein at least one of the one or more keys comprise a plurality of layers, said layers including ' ⁇ , first at least partially transparent layer, and a second layer, at least selected areas of said second layer having a degree of contrast in opacity and/or colour, said first and second layers being associated with a substrate layer having an obverse surface and a reverse surface, wherein means are provided for furnishing said substrate layer with a partially transparent tinted appearance, and wherein said first layer comprises a coating comprising a transparent carrier in which are supported non-opaque particulate light splitting or light frequency modifying materials, said materials being capable of causing light splitting effects when viewed in light falling in a direction of the obverse surface of said substrate layer, and wherein further said second layer provides said at least selected areas rearwardly of said first layer which are of pre-determined size and shape, the construction and arrangement being such that the light-splitting or modifying effects caused by said part
  • a suitable first layer* may be provided by comprising at least a substantially transparent carrier containing particulate semi-transparent colour producing materials.
  • a suitable material may be a flaked iridescent material of the kind exemplified by mica. Mica flakes may be pre-coated with ultra-thin layers of pigment, for example, oxides of metals such as titanium or iron.
  • the visual effect of the presence of the pigment may be varied according to the thickness of the pre-coating. Variations may also be observed in accordance with a base colour of the substrate layer and degree of translucency thereof.
  • said second layer may be provided as graphics in the form of information symbols applied in a discontinuous layer of an opaque or a substantially opaque pigment.
  • said pigmented material may be printed pigmented ink or the like.
  • said second layer may by colour tinted in a contrasting hue so that the colour tint is visible only on the passage of light from a source located at a reverse side of the at least one key.
  • a key pad having one or more keys, wherein at least one of the one or more keys comprise a substrate layer and a coating layer applied to an obverse surface of the layer, said coating comprising non-opaque particulate light frequency modifying materials entrained in a carrier therefor, said particulate materials being capable of causing light splitting effect ' s when viewed in light falling upon the coated obverse surface, wherein said substrate layer is non-opaque except where provided with a layer comprising opaque or substantially opaque areas which are of pre-determined size and shape, the construction and arrangement being such that the light-splitting or modifying effect caused by the particulate material and visible in ambient light is suppressed by the passage of light from a source located at a reverse side of the at least one key so that the presence of the opaque areas become visible from an obverse side of the key.
  • the at least one key(s) may be comprised of a partially transparent panel substrate which is of the kind referred to as smoke coloured.
  • the colour may, if preferred, be imparted to the keys(s) in a third layer which may be applied by a printing technique, but if preferred, may be obtained by the inclusion of pigment in the plastics film or other material of the key(s) substrate. It may be found that high quality visual effects are obtained with the use of pigments of a relatively dark hue.
  • the first layer may be provided by coating the substrate with a layer including ultra-thin flakes of mica that in the present example has been pre-coated with titanium dioxide.
  • the coated flakes are capable of splitting light into its visible component colours, the apparent colour depending upon the thickness of the titanium dioxide layer on the mica. This, varies in the present examples from 40 to 160 nm giving a range of colour from silver-white through copper-red, lilac, vivid blue, turquoise and finally green, the colour sequence being repeated as additional thickness is imparted to the titanium dioxide layer.
  • colour changes may be seen according to an angle from which the coated mica flakes are observed, the so-called interference colour being visible only at the glancing angle. Colours seen at other angles will differ. For example, if a blue "interference" layer of pigmented material forms a coating on a white background, then the light reflected at the glancing angle is blue and masks the complementary colour yellow which is seen at other angles. On a coloured background, the transparency of the coating permits the background colour to be visible through the coating, but at the glancing angle the interference colour predominates. On a curved key both colour effects may be observed at the same time on differing areas of- the key to give a visually pleasing effect.
  • a light source behind the key(s) will allow light from that source to penetrate the key(s) and the pigmented coating of the first layer. If the light from behind the key(s) is of greater intensity than ambient light falling on the obverse surface of the facia key(s) the colour effect visible in the first layer will be suppressed and the colours of the second layers will predominate as the keys "lights up".
  • the provision of graphics if present in the second layer will permit symbols to be visible, eg. as dark or darker areas against the back-lit key(s) .
  • a key pad assembly adapted to provide a variable visual appearance and including a key(s) according to the first aspect of the invention.
  • the key pad assembly may comprise a facia having one or more apertures, each aperture being adapted to receive a key of the key pad.
  • the facia may be made from an opaque material.
  • the facia may also be formed from a plurality of layers in a similar manner to the key(s) .
  • the key pad and facia are advantageously mounted relative to one another.
  • the assembly may further comprise a light source such that, in use, light from the source falls on a reverse surface of the key(s) .

Abstract

La présente invention concerne des claviers adaptés à donner une information ou d'autres données, que l'on peut regarder dans des conditions différentes de lumière et/ou dans un but purement décoratif. Le côté d'observation du clavier est recouvert d'une première couche (8) d'un matériau transparent ou partiellement transparent qui contient des fragments de matériau translucide tel que du mica à iridescence de couleur augmentée à l'aide d'un revêtement d'oxyde métallique adéquat. Le côté opposé du clavier est recouvert d'une couche (12) contenant un matériau pigmenté, par exemple sous forme de caractères ou d'autres formes qui s'affichent par rétro-éclairage à l'aide d'une source de lumière (15) suffisamment puissante afin de supprimer l'iridescence de la couche (8), visible en lumière ambiante, permettant ainsi de faire effectivement disparaître ce qui était visible sur la face d'observation et de rendre visible, à l'observateur, la couche (12) de caractères.
