Problems solved by technology

[0004] However, the plasma in the sputtering process easily damages the underlying organic material layer 14 and destroys its light-emitting characteristics.
Furthermore, the oxygen added in the sputtering process for forming a transparent conductive layer (eg, indium tin oxide) can also easily cause the thin metal layer to oxidize and destroy the electron injection ability (electron injection ability)

Abstract

The invention discloses a system for displaying images. The system for displaying images includes an organic light-emitting device including an anode layer on a substrate, a cathode layer and an organic light-emitting layer disposed between the anode and cathode layers. The cathode layer includes a metal layer in direct contact with the organic light-emitting layer, a transparent conductive layer, and an organic buffer layer with a carrier mobility in a range of 10-3 cm2 / (Vs) to 10-5 cm2 / (Vs) disposed between the metal layer and the transparent conductive layer.

Description

technical field [0001] The present invention relates to a flat panel display (flat panel display, FPD) technology, in particular to an organic light-emitting device (organic light-emitting / electroluminescent device, OLED / OELD). Background technique [0002] In recent years, with the advancement of electronic product development technology and its increasingly wide application, such as the advent of mobile phones, personal digital assistants (PDAs) and notebook computers, etc., compared with traditional displays, they have smaller volume and The demand for flat panel displays (FPDs) with power consumption characteristics is increasing day by day, and has become one of the most important electronic application products at present. Among flat-panel displays, organic electroluminescent devices will undoubtedly become the best choice for next-generation flat-panel displays due to their characteristics such as self-luminescence, high brightness, wide viewing angle, high response s...
