Einleitung

Das OLED (Organic Light Emitting Diode) -Display ist heller und hat einen höheren Kontrast. Es hat schnellere Zugriffszeiten, einen breiteren Blickwinkel, berbraucht weniger Strom als ein übliches VFD, LED or Liquid Crystal Displays. OLED displays sind selbsteuchtend wegen ihres organischen Materials und benötigen keine Hintergrundbeleuchtung für
alle Umgebungen. Dies erlaubt ebenfalls eine wesentlich dünnere Bauweise als Standard LCDs oder VFDs. Newhaven Display OLED displays werden als einfach anzuwendende Charakter oder  Grafik Module angeboten. Die Charakter Module werden farblich monochrome in Standard oder Slim ( schlank ) Abmessungen angeboten. Die grafischen OLED displays  sind monochrom und als Voll-Farb-Module verfügbar.





Newhaven Display Character OLED Displays

Newhaven Display's Character OLED modules come in standard sizes and can be used as compatible replacements for LCD or VFD modules. They use serial or parallel MPU interfaces; have LCD compatible instructions and 4 built-in font tables.

The Slim Character OLEDs are sleek displays, ideal for new product designs which require a 5mm profile display that can operate with battery power at -40°C to +85°C temperatures. These Slim Character OLEDs also provide a more affordable option while still offering vivid quality at a 10,000:1 contrast ratio. The Slim OLEDs also provide additional color options including yellow, red, blue and green.

Newhaven Display Graphic OLED Displays

Newhaven Display's Graphic OLED modules are easy to use, all-in-one designs. Most Graphic OLED displays require multiple high-voltage power supplies and external logic components. Newhaven Display's custom designed module boards for each Graphic OLED allow the user to have just one interface supply. The Graphic OLED module board has all the required external logic components, making it fast and easy to start using the displays.

Newhaven Display's graphic OLEDs stepped up to a whole new level once adding 18-bit full color graphic options. These full color OLEDs are passive matrix displays and are available in 128x96, 128x128 and 160x128 resolution sizes. Newhaven Display's full color OLEDs include a module containing all necessary logic, have built-in sleep mode and 256-step brightness. Available upon request, these full color OLEDs can also include a resistive or capacitive touch panel.

OLED Display Struktur

oled display structure

OLED Displays are made up of a layer of organic material placed between two conductors. These two conductors (an anode and a cathode) are then between a glass top plate (seal) and a glass bottom plate (substrate). When an electric current is applied to the two conductors, the organic material produces a bright, electro-luminescent light. When energy passes from the negatively charged layer (cathode) to the other (anode) layer, it stimulates the organic material between the two, which in turns emits lights that is visible through the outermost layer of glass.

Wie OLEDs Farbe erzeugen

color oled pixels

In order for OLED displays to produce color, an electric current is needed to stimulate the relevant pixels on the OLED display. The pixels are created by the arrangement of the cathodes and anodes; which are arranged perpendicular to each other. The electric current applied to the selected strips of anodes and cathodes determine which pixels get turned on and which pixels remain off. The brightness of each pixel is proportional to the amount of applied current.

Wie Farb OLEDs arbeiten

color oled diagram

Color OLEDs consist of a metal cathode with a negative charge, an electron transport layer, organic material, a hole transport layer, and an anode with a positive charge. The cathode and anode are arranged perpendicular to each other, creating a pixel where they intersect. Each pixel of a color OLED is divided into red, green, and blue sub-pixels. When the controller sends an electric current to a particular pixel, the current passes through the organic material causing the material to emit light. By adjusting the intensity of the electric current in each red, green, and blue sub-pixel, specific colors and gradients can be created.

Wie OLEDs Licht emittieren


oled display pixel arrangement
    1. Electrical current flows from the Cathode to the Anode through the organic layers, giving electrons to the emissive layer and removing electrons from the conductive layer.
    2. Removing electrons from the conductive layer leaves holes that need to be filled with electrons in the emissive layer.
    3. The holes jump to the emissive layer and recombine with the electrons. As the electrons drop into the holes, they release their extra energy as light.
