Organic light-emitting device and manufacture method thereof

Abstract

The invention relates to an organic light-emitting device and a manufacture method thereof. The organic light-emitting device comprises a glass substrate (1), a transparent conductive film layer (2), an organic light-emitting layer (3) and a metal electrode layer (4) from bottom to top. A rough region (6) is formed on the glass substrate (1), and the metal electrode layer (4) penetrates through the organic light-emitting layer (3) from the rough region (6) to be connected with the transparent conductive film layer (2) under the organic light-emitting layer (3). The organic light-emitting device has the advantages that no organic and metal mask plates is needed when the device manufactured by the method leading electrodes through the rough region (6), cost on manufacture, clean, maintenance, storage and the like of the expensive organic and metal mask plates can be reduced, the structure of a vacuum evaporation device is simplified, product specifications cannot be limited by types of the mask plates, and diversification of the product can be achieved.

Description

technical field [0001] The invention relates to an organic electroluminescence device and a manufacturing method thereof, and belongs to the technical field of plane display solid-state lighting. Background technique [0002] Existing organic electroluminescent devices, such as figure 2 As shown, it includes glass substrate (1), transparent conductive film (2), organic light-emitting layer (3) and metal electrode layer (4) from bottom to top. The traditional lead electrode method is as follows figure 2 As shown: in the first step, a predetermined electrode pattern (7) is formed on the transparent conductive film by means of photolithography or laser, and the transparent conductive film is divided into two areas, a and b, where the current is not connected; the second In the second step, the glass completed in the first step is placed on the organic mask in the organic vacuum evaporation chamber, and the organic light-emitting layer is evaporated after alignment to form a li...

AI Technical Summary

Problems solved by technology

[0003] This traditional lead electrode method requires the positioning of the organic mask and the metal mask. The product model is limited by the pattern and size of the organic and metal mask that has been molded, which is not conducive to product diversification. Replacement products Modeling requires expensive organic and metal mask mold opening fees, and regular cleaning, maintenance and testing of organic and metal masks is required. The requirements for vacuum evaporation equipment are high, and matching mask alignment and pressing are required. integrated system
