An organic electroluminescence device and its manufacturing method

Abstract

An organic electroluminescent device and its manufacturing method. The invention provides an organic electroluminescent device, which comprises a glass substrate (1), a transparent conductive thin film layer (2), an organic luminescent layer (3) and a metal electrode layer (4) from bottom to top, and a glass substrate (1) A rough area (6) is included on the surface, and the metal electrode layer (4) passes through the organic light-emitting layer (3) in the rough area (6) to connect with the transparent conductive film (2) under the organic light-emitting layer (3). The present invention has the following technical effects: the production of such a device including the method of passing through the rough region (6) leading electrode does not require organic and metal masks, and can save expensive organic and metal mask manufacturing, cleaning, maintenance, and storage and other costs, simplify the structure of vacuum evaporation equipment, product specifications are not limited by the mask plate model, and it is easy to realize product diversification.

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
