Problems solved by technology
[0006] Although the above method can effectively detect the encapsulation effect of the organic light-emitting diode, its manufacturing process is relatively complicated and the cost is relatively high. Moreover, in order to prevent the mutual interference between the energized electrode 10 and the test electrode 5 from affecting the accuracy of the measurement results, in An insulating layer 6 is also provided between the sealing layer 3 and the test electrode 5, which makes the overall structure of the organic light emitting diode more complex and increases the number of manufacturing steps.

An organic light emitting display (OLED) panel and a manufacturing method therefor, and a detection method for a packaging effect. The organic light emitting display panel comprises: a substrate (20), a cover plate (40) arranged opposite to the substrate (20), an organic light emitting display element (22) arranged on the substrate (20), a humidity-sensitive film (42) arranged on the cover plate (40), and a sealant frame (60) which bonds the substrate (20) and the cover plate (40) together. A confined space (246) is formed among the substrate (20), the cover plate (40) and the sealant frame (60). The organic light emitting display element (22) and the humidity-sensitive film (42) are both sealed in the confined space (246). A plurality of test leading wires (44) are arranged between the humidity-sensitive film (42) and the cover plate (40), wherein one end of each test leading wire (44) is electrically connected to the humidity-sensitive film (42), and the other end thereof is extended to the outside of the confined space (246) from the sealant frame (60) and used for electrically connecting a measurement apparatus.
Description
Technical field [0001] The invention relates to the field of flat display, in particular to an OLED panel, a manufacturing method thereof, and a method for detecting packaging effects. Background technique [0002] Flat display devices have many advantages such as thin body, power saving, and no radiation, and have been widely used. The existing flat display devices mainly include liquid crystal display devices (LCD, Liquid Crystal Display) and organic light emitting display devices (OLED, Organic Light Emitting Display). [0003] Organic light-emitting display devices have the characteristics of self-luminescence, high brightness, wide viewing angle, high contrast, flexibility, and low energy consumption. Therefore, they have received widespread attention. As a new generation of display methods, they have begun to gradually replace traditional liquid crystal display devices. Widely used in mobile phone screens, computer monitors, full-color TVs, etc. OLED display technology is d...
