Method for inspecting packaging effectiveness of OLED panel

摘要

The present invention provides a method for inspecting packaging effectiveness of an OLED panel, including: (1) in a manufacture process of an OLED component, forming a test block on a substrate, wherein the test block is made of an active metal, and then forming a plurality of test electrodes, wherein each of the test electrodes has an end connected to the test block and an opposite end extending to the outside for connection with a measurement device; (2) packaging an OLED panel so that said opposite ends of the test electrodes extend out of an enclosing frame; (3) electrically connecting the measurement device to the test electrodes to measure an actual conductivity of the test block; and (4) determining packaging effectiveness according to the actual conductivity. The method of the present invention makes use of conductivity differential of a test block made of an active metal in environments having different water/oxygen content to detect, in a more precise manner, the water/oxygen content in a packaged OLED panel so as to correctly determine the effectiveness of packaging.

1. A method for inspecting packaging effectiveness of an OLED panel, comprising the following steps:
(1) in a manufacture process of an OLED component, forming a test block on a substrate, wherein the test block is made of an active metal, and then forming a plurality of test electrodes, wherein each of the test electrodes has an end connected to and overlying the test block and an opposite end extending to the outside for connection with a measurement device; (2) packaging an OLED panel, wherein the packaged OLED comprises an enclosed space formed by the substrate, a lid and an enclosing frame arranged between the substrate and the lid, the OLED component having an anode, an organic layer and a cathode arranged in that order is disposed in the enclosed space, the test block is disposed in the enclosed space and spaced from the anode, the organic layer and the cathode, and the opposite ends of the plurality of test electrodes extend out of the enclosed space; (3) electrically connecting the measurement device to the test electrodes to measure an actual conductivity of the test block; and (4) determining packaging effectiveness according to the actual conductivity.
