Company News >> Notebook love it! Do you really understand the OLED screen? 5th,Dec,2017

Now more and more notebook manufacturers began to try OLED screen, as a new type of screen, OLED has no backlight, can be self-luminous, larger viewing angle, more colorful, energy-saving, flexible bending and so on .

However, the application is not so much in the notebook, heard more OLED burning screen and other reports. What kind of advantages and disadvantages of this screen type in the end, rely on fly? And its past lives. This article may be able to help you.

OLED screen past life

Organic Light-Emitting Diode (OLED), also known as Organic Electroluminescence Display (OELD), organic light emitting semiconductor, and thin film transistor liquid crystal display are different types of products, The former has the advantages of self-luminescence, wide viewing angle, high contrast, low power consumption, high reaction rate, full colorization and simple manufacturing process. However, the former has the advantages of large panel price, technical selectivity, longevity, resolution and color reproduction Can not match the latter.

Organic light-emitting diode displays can be divided into monochrome, colorful and full-color and other categories, of which full-color production technology is the most difficult, according to the organic light-emitting diode display drive can be divided into different passive (Passive Matrix, PMOLED) and active Active Matrix, AMOLED).

Organic light-emitting diodes can be simply divided into organic light-emitting diodes and polymer light-emitting diodes (polymer light-emitting diodes, PLED) are two types, have been developed into mature products. The main advantage of polymer LEDs versus organic LEDs is their large area display. However, due to the problem of product life, currently the products in the market are mainly organic light-emitting diodes.

Initially observed for electroluminescence in organic materials, André Bernanose, in the 1950s, and his colleagues at the University of Nancy in France, Martin Pope and some of his colleagues at New York University in 1960 developed ohmic contacts with organic crystals Ohmic dark-injecting electrode.

They further described the energy requirements for the hole injection electrode contacts and the electron injection electrode contacts. These are the foundations of charge injection in all modern OLED devices.

Pope's group also first observed the DC electroluminescence of a single pure anthracene crystal and a tetracene-doped anthracene crystal under vacuum by using a small silver electrode at a voltage of 400 volts and proposed a field-accelerated electron excitation Molecular fluorescence mechanism.
