Abstract

The device is made as a web material, whereby the electrical localization of optically active image points is achieved by the use of fibre material with increased electrical resistance

Description

Technisches GebietTechnical field

Die Erfindung betrifft einen Dünn-Bildschirm mit diskreter optischer Auflösung, welcher aus gewobenem Material besteht, mechanisch flexibel ist und dessen Bildpunkte matrizenförmig angeordnet sind, wobei sich die Bildpunkte an den Kreuzpunkten der Gewebefäden während der Herstellung des Gewebes und während des Betriebes selbständig elektrisch lokalisieren.The invention relates to a thin screen with discrete optical resolution, which consists of woven material, is mechanically flexible and its pixels are matrix-shaped are arranged, with the pixels at the cross points of the Fabric threads during the manufacture of the fabric and during the Automatically locate the company independently.

Stand der TechnikState of the art

Heutige Bildschirme werden planar auf Basis einzelner Bildpunkte hergestellt, wie etwa in Grossanzeigetafeln mittels Leuchtdioden, oder Flüssigkeitskristall-Anzeigen von tragbaren Computern (Laptops). Diese Bildschirme sind mechanisch steif, empfindlich auf mechanische Beanspruchung wie Druck oder Torsion und besitzen aufgrund ihres Aufbaus eine nicht zu unterschreitende Mindestdicke. Zudem müssen bei der Herstellung die einzelnen Bildpunkte des Bildschirms explizit festgelegt werden, was zusätzlichen Aufwand erfordert.Today's screens become planar based on individual pixels manufactured, such as in large display panels using LEDs, or liquid crystal displays from portable computers (Laptops). These screens are mechanically stiff, sensitive to mechanical stress such as pressure or torsion due to its structure, it should not be undercut Minimum thickness. In addition, the individual must Pixels of the screen are explicitly set what requires additional effort.

Technische AufgabeTechnical task

Gegenstand der Erfindung ist der Aufbau eines Bildschirms, welcher räumliche Flexibilität besitzt und somit reversibel verformt werden kann, eine dünne Ausdehnung in die Tiefe hat und bei welchem die einzelnen Bildpunkte durch das Zusammenfügen der Einzelteile selbständig gewonnen werden.The invention relates to the construction of a screen, which has spatial flexibility and is therefore reversibly deformed can have a thin expansion in depth and at which the individual pixels by combining the Individual parts can be obtained independently.

Darstellungpresentation

Erfindungsgemäss wird dies bei einem Bildschirm des obigen Typs dadurch erreicht, dass der Bildschirm durch räumlich flexibles Fadenmaterial gewoben wird, welches optisch arbeitet wie auch mechanisch dem Bildschirm genügend Festigkeit verleit sodass er sehr dünn aufgebaut werden kann und dabei räumlich flexibel bleibt. Durch den Vorgang des Webens sowie durch die elektrische Bauart des optisch aktiven Fadenmaterials entstehen an den Kreuzungspunkten der Quer- und Längsfäden automatisch die für die einzelnen Bildpunkte notwendige elektrische Lokalisierung.According to the invention, this is the case of a screen of the above type thereby achieved that the screen through spatially flexible Thread material is woven, which works optically as well mechanically entices the screen enough strength so that it can be built very thin and at the same time spatially flexible remains. Through the process of weaving as well as through the electrical Design of the optically active thread material arise on the Crossing points of the transverse and longitudinal threads automatically those for the electrical localization necessary for individual pixels.

Vorteilhafte WirkungBeneficial effect

Ein erfindungsgemässer Bildschirm weist verschiedene Vorteile auf. Durch die Maschenform innerhalb des Gewebes wird Oberflächenlänge des Bildschirmmaterials gewonnen, wodurch eine höhere reversible Biegsamkeit als mit dem gestreckten Material alleine ermöglicht wird. Eine spezielle Kontaktierung zur elektrischen Lokalisierung der Bildpunkte entfällt, wodurch der Bildschirm dünner aufgebaut werden kann sowie der Aufbau und die Herstellung gegenüber dem Stand der Technik vereinfacht wird. Der Aufbau als Gewebe integriert elektrische, optische und mechanische Funktionen in demselben Material. A screen according to the invention has various advantages. The mesh shape within the fabric makes the surface length of the screen material gained, making a higher reversible Flexibility than is possible with the stretched material alone becomes. A special contact for electrical localization the pixels are omitted, which makes the screen thinner can be as well as the structure and manufacture compared to the State of the art is simplified. The structure as a fabric integrates electrical, optical and mechanical functions in the same material.

Weg zur AusführungWay of execution

Fig. 1 zeigt ein Beispiel für den Aufbau des erfindungsgemässen Gewebes mit den optisch aktiven Querfäden (1), den stromleitenden Längsfäden (2), sowie den Stützfäden in beiden Richtungen (3, 4).Fig. 1 shows an example of the structure of the inventive Fabric with the optically active cross threads (1), the electrically conductive Longitudinal threads (2) and the support threads in both directions (3, 4).

Fig. 2 zeigt die elektrische Kontaktierung sowie die Lokalisierung der Bildpunkte. Durch die Kreuzung von Quer- und Längsfäden entsteht ein elektrischer Kontakt, welcher zur Anregung des optisch aktiven Materials im Querfaden benutzt wird. Die Anregung findet im Bereich (5) statt. Damit sich der Strom nicht auf der gesamten Länge des optisch aktiven Querfadens ausbreitet, besitzt der Querfaden einen elektrischen Widerstand R so, dass sich eine lokale Potentialzone um den Kreuzungspunkt von Quer- und Längsfaden bildet. Damit wird verhindert, dass durch die Anregung eines einzelnen Punktes gleich die gesamte Länge eines Querfadens optisch aktiv wird.2 shows the electrical contact as well as the localization the pixels. By crossing transverse and longitudinal threads An electrical contact is created which excites the optically active material is used in the cross thread. The suggestion takes place in area (5). So that the electricity is not on the spreads the entire length of the optically active transverse thread the transverse thread has an electrical resistance R such that there is a local potential zone around the cross point of cross and Longitudinal thread forms. This prevents the excitation of a single point equals the entire length of a cross thread becomes optically active.

Fig. 3 zeigt den Querschnitt durch einen möglichen Aufbau des optisch aktiven Querfadens. Um eine elektrisch leitende Innenleitung (6) befindet sich konzentrisch das optisch aktive Material (7), welches seinerseits konzentrisch durch eine Aussenhülle (8) mit erhöhtem elektrischem Widerstand R umhüllt wird. Das optisch aktive Material (7) kann dabei entweder selbst aktiv leuchten, wie beispielsweise als längsförmig aufgebaute organische Leuchtdiode (OLED), oder passiv das Licht einer Hintergrundbeleuchtung temporär passieren lassen, wie beispielsweise als Flüssigkeitskristall-Aufbau.Fig. 3 shows the cross section through a possible structure of the optically active cross thread. To be an electrically conductive Inner line (6) is concentrically the optically active Material (7), which in turn is concentric by a Outer shell (8) covered with increased electrical resistance R. becomes. The optically active material (7) can either itself actively shine, such as a longitudinal structure organic light emitting diode (OLED), or passively the light of a Let backlight pass temporarily, like for example as a liquid crystal structure.
