Abstract

A glass panel/window which enables continuously variable light transmission has many applications in various branches of industry and everyday life, which often result in valuable and significant savings in power consumption and improved living standards, and has been developed from the liquid crystal display (LCD) conceptual method. A homogeneous distribution of the liquid crystals is obtained which results in a variation in the position and in the degree of transmittance by the application of a controlled DC voltage.

Aufgabe der ErfindungObject of the invention

Das Ziel unserer Produkt und Verfahrensentwicklung ist eine Glasscheibe, die bei möglichst geringem Energieverbrauch den Lichdurchfluß stufenlos regeln kann.The goal of our product and process development is one Glass pane that with the lowest possible energy consumption Can regulate light flow continuously.

Grundlage dafür wird die Weiterentwicklung der bekannten LCD Anzeige (nach der Abkürzung für englisch Liquid Crystal Display: Flüssigkristallanzeige) sein. The basis for this will be the further development of the well-known LCD Display (after the abbreviation for English Liquid Crystal Display: Liquid crystal display).  

Lösung der AufgabeSolution of the task

Bei der Beschichtung der Glasscheibe entfällt die eigentliche Maske, die bislang notwendig war um Balken und Sonderzeichen zu erzeugen. Dadurch erhalten wir eine homogene Verteilung der Flüssigkristalle, die wiederum durch anlegen einer regelbaren Gleichspannung ihre Lage und damit den Grad der Durchsichtigkeit verändern.When coating the glass pane, the actual one is omitted Mask that was previously necessary around bars and special characters to create. This gives us a homogeneous distribution of the Liquid crystals, which in turn by creating an adjustable DC their location and thus the degree of Change transparency.

Entfernen wir nun auch noch den in LCD Anzeigen notwendigen Reflektor, in der Regel wird dort Metallfolie eingesetzt, dann erhalten wir eine durchsichtige Glasscheibe die sich beim anlegen einer Steuspannung verdunkelt.Let us now remove the one necessary in LCD displays Reflector, usually metal foil is used there, then we get a transparent glass pane that is put on when you put it on darkened from a voltage.

Vorteile der ErfindungAdvantages of the invention

  • 1. "dunkelgesteuerte" Fenster verwehren Fremden oder auch Einbrechern den Durchblick. So daß z. B. die liegengelassene Videokamera auf dem Rücksitz des Autos den potentiellen Dieb nicht mehr zum Einbruch animiert.
    Gleichzeitig erhöht sich das Risiko für den Einbrecher erwischt zu werden, schließlich könnte ja auch z. B. ein Pitbull dort ein Nickerchen machen.    1. "Dark-controlled" windows prevent strangers or burglars from seeing through. So that z. B. the abandoned video camera in the back seat of the car no longer encourages the potential thief to break in.
    At the same time, the risk of being caught by the burglar increases. B. take a pit bull there napping.
  • 2. "dunkelgesteuerte" Fenster vermindern die Sonneneinstrahlung, d. h. z. B. der Fahrzeuginnenraum des abgestellten PKW wird nicht so stark aufgeheizt.2. "dark-controlled" windows reduce solar radiation, d. H. e.g. B. the vehicle interior of the parked car will not heated up so much.
  • 3. Die Raumhelligkeit in Gebäuden und Fahrzeugen ließe sich mit Hilfe von entsprechenden automatischen Reglern z. B. Dämmerungsschalter oder Solarzelle über einen großen Tageszeitraum konstant halten.3. The room brightness in buildings and vehicles can be with Help from appropriate automatic controllers such. B. Twilight switch or solar cell over a large one Keep the daily period constant.
  • 4. Wohnräume lassen sich schnell und unkompliziert z. B. mit einer Fernbedienung, oder einer Zeitschaltuhr entsprechend den persönlichen Anforderungen gestalten.4. Living rooms can be quickly and easily z. B. with a Remote control, or a timer according to the design personal requirements.
  • 5. Kostenvorteil für die Kunden:
    • - kostenaufwendige Installation von Rollläden können entfallen
    • - Versicherungstechnische Vorteile bei geringerer Schadensbilanz (siehe Pkt. 1)
    • - Klimaanlagen in Kraftfahrzeugen und Gebäuden verbrauchen weniger Energie da der Innenraum nicht mehr so stark aufgeheizt wird
    • - da es sich bei der dimmbaren Scheibe um ein passives Bauelement handelt, entstehen kaum, oder bei Verwendung einer Solarzelle keine Energiekosten.
    • - da die dimmbare Scheibe keine mechanisch bewegten Bauteile besitzt, entstehen auch keine Wartungskosten
    5. Cost advantage for customers:
    • - Costly installation of roller shutters can be omitted
    • - Technical advantages with a lower loss balance (see point 1)
    • - Air conditioning systems in motor vehicles and buildings use less energy because the interior is no longer heated as much

Beispielexample

Jeder der eine Digitaluhr mit LCD Anzeige besitzt, wird beim ablaufen der Batterie, also beim absenken der Batteriespannung feststellen, das die eigentlich zur Anzeige gedachten Balken langsam bis zur Durchsichtigkeit verblassen.Anyone who has a digital clock with LCD display will run out when the battery runs out lower the battery voltage determine that the actually intended for display Slowly fade the bars to transparency.

Stellt man sich nun vor, daß dieser Anzeigebalken der Uhr die Größe einer Fensterscheibe annimmt, dann ließe sich deren Lichtdurchlässigkeit z. B. mit Hilfe eines Potentiometers stufenlos regeln.Now imagine that this clock display bar is the size of a window pane assumes, then their translucency z. B. with the help of a potentiometer regulate continuously.

Bedenkt man dabei, das es sich bei der LCD Anzeige um ein passives Bauelement handelt, so wird klar, daß der zu erwartende Energieverbrauch sehr gering, also auch von einer im Fensterrahmen eingebauten Solarzelle übernommen werden kann, siehe Anlage 1.If you consider that the LCD display is a passive component, it becomes clear that the expected energy consumption is very low, i.e. it can also be taken over by a solar cell installed in the window frame, see Appendix 1 .

Somit entfällt auch eine externe Stromversorgung und aufwendige Verkabelung des Fensters. Zusätzlich zum dargestellten Drehpotentiometers, lässt sich natürlich auch ein Dämmerungsschalter installieren. Dadurch wird es möglich sein, die Raumhelligkeit über einen großen Tageszeitraum automatisch konstant zu halten.This also eliminates the need for an external power supply and complex wiring of the window. In addition to the rotary potentiometer shown, it can of course also be used Install the twilight switch. This will allow the room brightness to be over to automatically keep a large daily period constant.

Erfolgt die Ansteuerung der "dimmbaren" Scheibe über einen Infrarot Empfänger, so lässt sich die Raumhelligkeit schnell und komfortabel mit einer Fernbedienung entsprechend den persönlichen Anforderungen einstellen.If the "dimmable" pane is controlled via an infrared receiver, then let the room brightness quickly and comfortably with a remote control according to the set personal requirements.

Als weitere Anwendung wäre der Einbau einer programmierbaren Zeitschaltuhr in den Fensterrahmen denkbar.Another application would be the installation of a programmable timer in the Window frames conceivable.

Damit erhält der Anwender die Möglichkeit, die Sonneneinstrahlung und natürlich auch den Einblick Dritter zu vorher programmierten Zeiten auszuschließen oder je nach eingestellter Dimmung einzuschränken.This gives the user the option of sun exposure and of course that Exclude third party insight at pre-programmed times or depending on the set one Restrict dimming.

Natürlich sind auch Mehrfachansteuerungen möglich.Multiple controls are of course also possible.
