Abstract

The colour display screen is formed using a matrix of light emitting diodes, each of three elements providing red, green and blue colours. Each stage has separate electrodes (AR, AG, AB) for the different colours and a common cathode (K). The stages are mounted on a circuit board in a solder bath process and are covered by a protective glass plate. The unit may be produced in different sizes. USE/ADVANTAGE - Sports stadium cinema tv television. Light, compact suited to automatic mass production.

Description

Elektronischer LED-Farbbildschirm, in unterschiedlichen Größen, zur Wiedergabe bewegter oder stehender Farbbilder.Electronic LED color screen, in different sizes, for Playback of moving or still color images.

1. Technisches Gebiet ist die elektronische Bildschirmtechnik;1. The technical field is electronic screen technology;

2. Stand der Technik ist die nicht bildträge, schwere Elektronenstrahl- Bildröhre, mit 1-3 oder mehr Elektronenstrahlen (bei Mehrstrahl- Oszilloskopen) und Aktiv-Matrix-LCD-Technik, bildträge;2. The state of the art is the heavy, electron beam Picture tube, with 1-3 or more electron beams (with multi-beam Oscilloscopes) and active matrix LCD technology, slow-moving images;

3. Aufgabenstellung: Einführung eines neuen, kostengünstigen, flachen, verbrauchsarmen, nicht bildträgen, elektronischen LED-Farbbild­ schirms weltweit;3. Task: Introduction of a new, inexpensive, flat, low-consumption, non-image-bearing, electronic LED color image umbrellas worldwide;

4. Anwendungen: in Sportstadien, Kinos, Werbeanzeigen, im Fernsehen, auch als Notebook-Computer-Monitore verwendbar;4. Applications: in sports stadiums, cinemas, advertisements, on television, can also be used as notebook computer monitors;

5. Vorteile sind: wesentlich geringere Bildträgheit (ns) als bei LCD- Farbbildschirmen, sehr große und flache Wandbildschirm-Konstruk­ tionen sind ebenfalls möglich. Helle Bilder, keine Implosionsgefahr, geringes Gewicht, geringe Wärmeentwicklung. Die gefährliche Hoch­ spannung von 30 oder mehr kV entfällt, ebenso die Katodenheizung - dadurch wird Energie gespart. LED haben eine wesentlich höhere Le­ bensdauer gegenüber Heizfäden-Bildröhren.5. Advantages are: significantly lower image inertia (ns) than with LCD Color screens, very large and flat wall screen construction tions are also possible. Bright pictures, no risk of implosion, low weight, low heat generation. The dangerous high voltage of 30 or more kV is eliminated, as is the cathode heating - this saves energy. LEDs have a much higher Le life compared to filament tubes.

6. Unter Bezugnahme auf § 4 und § 6 ergibt sich ein flacher Farbbild­ schirm in Rechteckform. Die LED-Fläche wird mit einem leicht getön­ ten Schutzglas abgedeckt, in einem Kunststoff-Füller eingebettet. Es werden spezielle, meist sehr kleine Leuchtdioden-Tripel gebildet, mit den ausgestrahlten Lichtfarben: rot (R), grün (G) und blau (B), (siehe Zeichnung) - gleicher Norm-Lichtstärke. Diese LED-Tripel werden zweckmäßig in je einem durchsichtigen Kunststoffgehäuse positionsgerecht zusammengefaßt, 3 getrennte Elektroden (3 Anoden: aR, aG, aB, das sind die P-leitenden Schichten, sie werden ange­ steuert), ein gemeinsamer 4. Anschluß (3 zusammengefaßte Katoden "K", also die N-leitenden Schichten werden an Masse-Minus gelegt), werden herausgeführt und an einer Leiterplatte im Lötbad angelötet. Zwischen Katoden und Masse wird ein Strombegrenzungswiderstand eingebaut.6. With reference to § 4 and § 6 results in a flat color screen in a rectangular shape. The LED surface is covered with a light-tinted protective glass, embedded in a plastic filler. Special, mostly very small triple LEDs are formed with the emitted light colors: red (R), green (G) and blue (B), (see drawing) - same standard light intensity. These LED triples are conveniently grouped together in a transparent plastic housing, 3 separate electrodes (3 anodes: a R , a G , a B , these are the P-conductive layers, they are activated), a common 4th connection ( 3 combined cathodes "K", that is, the N-conductive layers are connected to ground minus), are led out and soldered to a circuit board in the solder bath. A current limiting resistor is installed between the cathodes and ground.

Die Arbeitsgänge lassen sich weiter vereinfachen, ein automatischer Fertigungs- und Prüfungsprozeß kann wunschgemäß eingeleitet werden. The operations can be further simplified, an automatic one The manufacturing and testing process can be initiated as required.  

Analog zu den bekannten IC-Herstellungsverfahren lassen sich auch kleinere Bildschirme/Monitore herstellen und funktionsprüfen. Das Temperaturverhalten der LED wird entsprechend kompensiert.Analogous to the known IC manufacturing processes, Manufacture smaller screens / monitors and test them. The temperature behavior of the LED is compensated accordingly.

Der flache LED-Rechteckbildschirm wird Punkt-für-Punkt zeilenweise mikroprozessorgesteuert um auch z. B. der Bild-im-Bild-Technik ge­ recht zu werden. Dadurch werden auch Bildvergrößerungen, Bildauf­ teilungen auf mehreren Bildschirmen, oder Bildausschnitte usw., mög­ lich.The flat rectangular LED screen becomes line-by-point line by line microprocessor controlled to z. B. the picture-in-picture technique ge to be right. This also enlarges the image divisions on multiple screens, or image sections etc., possible Lich.

Ansteuerung mit Wechselstrom (wie beim LCD) ist nicht erforderlich. Flimmerfreie 100-Hz-Technik ist ebenfalls anzuwenden.Control with alternating current (as with the LCD) is not necessary. Flicker-free 100 Hz technology is also to be used.

Verwendung geringster Abstände zwischen den Leuchtdioden und zukunftsweisender Digitaltechnik, hat eine sehr gute Bildqualität zur Folge. Die meisten bisher bekannten Farbbildschirme haben lediglich die Bewertung "gut" erhalten. Es sollen künftig eben auch sehr gute Bildschirme hergestellt werden - eine lohnende Zielsetzung.Use of the smallest distances between the LEDs and forward-looking digital technology, has a very good image quality result. Most color screens known to date have only received the rating "good". In the future, it should also be very good screens are made - a worthwhile objective.
