Problems solved by technology

As a result, not only is it difficult to control its purity, but it is also highly dangerous
Due to the extremely high risk, this cathode process is not suitable for the mass production process of monochrome or full-color inkjet printing of polymer light-emitting diode components.

Embodiment 1

[0039] Such as figure 2 Shown is a schematic cross-sectional view of an organic electroluminescent device according to an embodiment of the present invention.

[0040] refer to figure 2 , the organic electroluminescent component in the figure is a two-layer structure component, which includes a transparent substrate 100, an anode 102, a light emitting layer 104, an ion-doped layer 105, a cathode 106, a cover plate 110 and a Frame glue 108. The method of forming the organic electroluminescent device is to sequentially form the anode 102 , the light emitting layer 104 , the ion-doped layer 105 and the cathode 106 on the transparent substrate 100 . Afterwards, a cover plate 110 is formed on the cathode 106, and a frame glue 108 is formed around the transparent substrate 100 and the cover plate 110, so as to encapsulate the organic electroluminescence component.

[0041] Wherein, the transparent substrate 100 is, for example, a glass substrate, a plastic substrate or a windab...

Abstract

The invention supplies a method to make organic electric-promoted component. The component includes: a base plate, a anode on the plate, a light emitting layer on the plate, a cathode on the layer, and a hydronium layer of impurities. And the hydronium layer of impurities adds 0.1%~10% LiClO4 or other hydronium compound to Alq3.

Description

technical field [0001] The invention relates to an organic electroluminescent component (OEL) and a manufacturing method thereof, in particular to an organic electroluminescent component with low driving voltage and a manufacturing method thereof. Background technique [0002] Currently, displays featuring light weight and high efficiency, such as liquid crystal displays, have been widely developed. However, LCD still has many problems, such as not wide enough viewing angle, not fast enough response time to be used in high-speed animation, and requiring a backlight which consumes more power, etc. In particular, there is still a problem in the liquid crystal display, that is, it is impossible to achieve a large-scale panel. [0003] However, there is now a new flat panel display technology that can solve the above problems. This new flat panel display is an organic electroluminescent display developed in recent years. An organic electroluminescent display is a display compo...
