Description

Beschreibung:Description:
Bildfläche oder DisplayImage area or display
Die Erfindung bezieht sich auf eine Bildfläche, die sich aus zahlreichen rasterartig angeordneten Bildelementen oder Pixeln zusammensetzt, wobei jeder Pixel mindestens einen Farbspiegel aufweist, der von einer flachen durchsichtigen Kammer gebildet wird, in die eine farbige Flüssigkeit ein- bringbar ist. Ein Pixel ist das kleinste Bildelement einer Bildfläche, dem Farbe und Intensität zugeordnet werden kann. Ein Pixel kann drei oder vier übereinander angeordnete Farbspiegel aufweisen, denen die Farben Rot - Grün - Blau oder die Farben Cyan - Magenta - Gelb und gegebenenfalls einem hinteren vierten Farbspiegel weiß oder Schwarz zugeführt werden.The invention relates to an image surface which is composed of numerous grid-like arranged pixels or pixels, each pixel having at least one color mirror which is formed by a flat, transparent chamber into which a colored liquid can be introduced. A pixel is the smallest picture element of a screen to which color and intensity can be assigned. A pixel can have three or four color mirrors arranged one above the other, to which the colors red - green - blue or the colors cyan - magenta - yellow and optionally a rear fourth color mirror are supplied in white or black.
Bildflächen und Pixel dieser Art sind bekannt aus US 6,037,955, EP 0 806 753 und EP 1 090 384.Image surfaces and pixels of this type are known from US Pat. No. 6,037,955, EP 0 806 753 and EP 1 090 384.
Die Pixel und Farbspiegel der bekannten Bildflächen oder Displays dieser Art haben in der Bildebene eine rechteckige, insbesondere quadratische Form und sind möglichst ohne Abstand neben- und übereinander angeordnet.The pixels and color mirrors of the known image areas or displays of this type have a rectangular, in particular square shape in the image plane and are arranged next to and above one another as far as possible without spacing.
Bei Displays oder Bildflächen, die von größerer Entfernung betrachtet werden und deren Pixel aus Kostengründen größer sein können, besteht bei derartigen rechteckigen oder quadratförmigen Pixeln oder Bildelementen der Nachteil, daß bei Betrachten der Bildfläche aus der Nähe ein störendes Gitter zu sehen ist, das sich aus horizontalen und vertikalen Linien zusammensetzt, die von den Trennwänden der die Farbspiegel bildenden Kammern erzeugt werden.In the case of displays or image surfaces which are viewed from a greater distance and whose pixels can be larger for reasons of cost, such rectangular or square-shaped pixels or picture elements have the disadvantage that an interfering grating can be seen when the image surface is viewed from close up composed of horizontal and vertical lines generated by the partitions of the color mirror forming chambers.
Der Erfindung liegt die Aufgabe zugrunde, eine Bildfläche zu schaffen, bei der auch bei naher Betrachtung das störende Gitter nicht oder nicht so stark in Erscheinung tritt. Ferner sollen die Farbspiegel der Bildfläche leicht elektronisch ansteuerbar sein, und die Stabilität der aus mehreren aus durchsichtigem Material bestehenden und von Kammern sowie Kanälen durchsetzten Schich- ten gebildeten Bildfläche soll verbessert werden. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Farbspiegel in der Bildebene die Form eines gleichschenkligen Dreiecks, insbesondere die Form eines gleichseitigen Dreiecks hat.The invention has for its object to provide an image area in which even at close inspection, the disturbing grid does not or not so strong in appearance. In addition, the color mirrors of the image surface should be easily electronically controllable, and the stability of the image surface formed by a plurality of transparent material and penetrated by chambers and channels should be improved. This object is achieved in that the color mirror in the image plane has the shape of an isosceles triangle, in particular the shape of an equilateral triangle.
Diese Form hat zur Folge, daß die Pixel auf dem Bildschirm nicht ein rechteckiges Raster bilden sondern eine zusammengesetzte Fläche mit ineinander verzahnten Pixel-Reihen. Hierdurch wird die störende Gitterstruktur auf dem Bildschirm vermieden. Das Bild wird durch das Auge des Betrachters erst viel später in einzelne Bildpunkte aufgelöst und kann daher mit geringerem Abstand betrachtet werden.The consequence of this shape is that the pixels on the screen do not form a rectangular grid but rather a composite surface with interleaved pixel rows. This avoids the disturbing grid structure on the screen. The image is resolved by the eye of the beholder much later into individual pixels and can therefore be viewed at a closer distance.
Diese Form der Farbspiegel und damit auch die Form der Pixel hat aber nicht nur optische Vorteile, sondern auch herstellungstechnische Vorteile bei der Herstellung einer aus mehreren durchsichtigen Schichten bestehenden Bildflä- che, die sich aus lückenlos aneinandergesetzten Pixeln und Farbspiegel zusammensetzt und von Kammern, Reservoirs und Kanälen durchsetzt ist.However, this shape of the color mirror and thus also the shape of the pixels not only has optical advantages, but also manufacturing advantages in the production of a consisting of several transparent layers Bildflä- surface, composed of gapless juxtaposed pixels and color mirrors and of chambers, reservoirs and Interspersed with channels.
Insbesondere wenn die Bildfläche aus Pixeln mit drei hintereinander angeordnete Farbspiegeln für die Farben Rot, Grün, Blau oder die Farben Cyan, Magenta, Gelb aufweisen können die Zuführkanäle für die drei Farbspiegel des Pixels im Querschnitt flach und an den drei unterschiedlichen Seiten des dreieckigen Pixels angeordnet sein.In particular, if the image area consists of pixels with three color levels arranged one behind the other for the colors red, green, blue or the colors cyan, magenta, yellow, the feed channels for the three color mirrors of the pixel can be arranged flat in cross-section and at the three different sides of the triangular pixel be.
Die Erfindung betrifft ferner einen Farbspiegel, der an einem Reservoir angeschlossen und von einer flachen durchsichtigen Kammer gebildet ist, wobei zwischen dem Reservoir und dem Farbspiegel ein Fluidstrom bewegbar ist, der sich zusammensetzt aus mindestens zwei nicht miteinander mischbaren Fluiden, von denen ein Fluid auch gasförmig sein kann und von denen ein anderes Fluid eine farbige Flüssigkeit ist. Sowohl mit dem Ziel der Vermei- düng des sichtbaren Gitters als auch mit dem Ziel der Vereinfachung des Aufbaus und der Herstellung kann der Farbspiegel über nur einen Kanal am Reservoir angeschlossen sein, über den die farbige Flüssigkeit dem Farbspiegel oder dem Reservoir zugeführt und gleichzeitig das klar durchsichtige Fluid abgeführt wird. Der Kanal kann im Querschnitt flach sein und seine Breite kann mindestens dreimal so groß sein wie seine Tiefe.The invention further relates to a color mirror, which is connected to a reservoir and formed by a flat transparent chamber, wherein between the reservoir and the color mirror, a fluid flow is movable, which is composed of at least two immiscible fluids, of which a fluid is also gaseous may be and of which another fluid is a colored liquid. Both with the aim of avoiding the visible grille and with the aim of simplifying the construction and manufacture, the color mirror can be connected to the reservoir via only one channel, via which the colored liquid is supplied to the color mirror or the reservoir and at the same time clear transparent fluid is discharged. The channel may be flat in cross-section and its width may be at least three times its depth.
