Embodiment

[0041] According to the structure of the above-mentioned specific embodiments, the full-color display device can be manufactured by the following steps (please refer to FIGS. 2A-2I ):

[0042] Cleaning the substrate 10 and the first electrode 12 formed thereon: organic solvent and deionized water ultrasonic vibration; nitrogen blow-drying; vacuum drying, the temperature is in the range of about 80°C to about 200°C; ultraviolet light ozone cleaning; oxygen plasma The body (oxygen plasma) is clean.

[0043] Forming the pixel pattern: coating the photosensitive polymer insulating material on the substrate 10 and the first electrode 12, forming the required pixel opening 13 and the insulating wall 13' pattern through the photoresist pattern, and each sub-pixel pattern corresponds to a Organic Electroluminescent Components.

[0044] Forming the hole transport layer 14: coating PEDOT / PSS by spin coating, and baking in an inert gas environment.

[0045] Forming the light-emitting l...

Abstract

The invention relates to a kind of organic electrization irradiance subassembly, it possesses irradiance layer, the irradiance layer includes macromolecule conducting main material which can be solidified by illumination, fits for colored display by spin coating method, and the irradiance layer includes at least one little molecule irradiance material to realize high irradiance efficiency. The subassembly can not be limited by molecular weight distributing of macromolecule conducting main material on color fineness.

Description

technical field [0001] The present invention relates to an organic electroluminescence component, in particular to a polymer organic electroluminescence component, the light-emitting layer of which contains a polymer conductive main material, and the polymer conductive main material has phototransition in the main chain or side chain functional group. The linking group can be cured by being cross-linked by light, and the light-emitting layer contains at least a small molecule of light-emitting material. Background technique [0002] The flat-panel display device composed of polymer organic electroluminescent components has many advantages, such as low manufacturing cost, long life, shock resistance, fast response, wide viewing angle, low driving voltage, thinness and large size. The material of the light-emitting layer and carrier transport layer of this light-emitting component is mainly conductive conjugated polymer, which is different from the organic electroluminescent c...
