Definitions

  • This invention relates to display panels for producing an unexpected visual effect such as the appearance of a coloured picture, message or advertising material.
  • the present invention seeks to provide a display panel which is patentably different from any known form of display panel.
  • the present invention proposes a display panel comprising a heat-sensitive sheet having a display surface and an opposed rear surface, said sheet incorporating a substance which causes the said display surface to undergo a change in its light-reflective properties when said layer is heated, characterised by electrical resistance heating means closely juxtaposed to selected areas of said sheet such that, when electrical power is applied to said heating means, said selected areas of the sheet are heated causing corresponding areas of the display surface to change its visual apprearance.
  • the panel may be rigid or flexible.
  • the display surface preferably undergoes a change in its light-reflective properties when heated.
  • the wavelength of the reflected light changes so that the panel undergoes a visible colour change.
  • the heating means may be arranged in the shape of an advertising logo or other material.
  • the sheet may include a hypercolour dye (i.e. a dye which temporarily changes colour on application of heat).
  • heating means may be integrally incorporated in the sheet it is preferably applied to the rear surface of the sheet so that it is not visible from the display surface.
  • the heating means may be secured to a carrier layer which is in turn applied to said rear surface of the sheet.
  • a preferred form of heating means comprises an elongate electrically conductive resistance heating element.
  • the heating means is preferably operated by sensor means which is arranged to produce electrical output signals in response to a predetermined triggeringmé.
  • the sensor means may be responsive to various triggering stimuli, including one of more of the following:
  • the output signals from the sensor means may be fed to electronic signal processing means which produces electrical signals for driving the heating means.
  • the processing means may comprise analogue electronics, combined analogue and digital electronics or a microcontroller.
  • the output signals preferably comprise a series of pulses which power the heating means.
  • the pulses may be separated by relatively long gaps.
  • the invention also provides a display panel comprising:
  • FIG. 1 is a general perspective view of a sweat shirt incorporating a display panel in accordance with the invention.
  • Figure 2 is a block diagram of part of the sweat shirt.
  • An item of clothing 1 (in this case a sweat shirt) is formed of cotton or other natural or synthetic textile materials.
  • a design 2 is printed on an area of the shirt using a hypercolour dye which undergoes a temporary colour change when heated.
  • a strip 3 (Fig. 2) of polyamide material incorporating a woven electrically conductive yarn is bonded to the rear (inside) surface of the shirt in registration with the design 2 using a general purpose adhesive. In the example shown, the strip measured about 7mm x 200mm and had a resistance of about 10 ohms.
  • the electrically conductive yarn comprises a bundle of extremely fine flexible electrically conductive fibres each being electrically insulated.
  • the hypercolour dye is applied uniformly to an area of the garment so that the design is formed solely by the shape of the electrical heating element 3 and is not normally visible on the outside surface of the garment.
  • the shirt also incorporates an integral waterproof pouch 4 which is conveniently concealed by being incorporated into a false pocket, badge or a seam of the garment.
  • the pouch contains a sound sensor 5 in the form of a miniature microphone which was connected to a controller card 6 including a variable gain amplifier 7.
  • the gain of the amplifier is automatically controlled to give a large dynamic range, so that the amplifier responds to a relative change in ambient noise level rather than the absolute level.
  • the signal received by the sensor 5 is thus processed by being amplified and peak detected to give an amplitude envelope which is compared with an adjustable reference voltage to produce a series of pulses.
  • the pulses are stretched by a timer to about 1 second and used to drive a switching device 8 which drives the strip 3 via wires 15 bonded to the opposite ends of the strip.
  • the card 6 is under the overall control of a microcontroller 10, which allows more sophisticated sound recognition to be employed if desired. Re-triggering of the switching device is inhibited for a period of up to one minute, which is significantly less than the time taken for the dye to revert to its original colour. After this period, re-triggering causes another one second heating pulse to be sent to the strip 3. Clearly the duration of the pulses and the intervening gaps will depend on the characteristic speed of colour change of the dye or other substance used.
  • the duration of the pulses and/or the gap between them may be controlled according to ambient temperature, by incorporating a suitable temperature sensor. This can significantly increase battery life.
  • the card is powered by a long-life lithium battery 12. Such a battery is capable of delivering several thousand one second pulses, giving a typical working life of between thirty and fifty hours.
