Problems solved by technology

However, the reliability and accuracy of detecting the encapsulation effect of the OLED display device using the above two methods are relatively low. Due to defects such as air holes and cracks in the packaging structure, it is impossible to detect OLED display devices in which water or / and oxygen penetrates into the packaging cavity through defects such as air holes and cracks, resulting in packaging failure; During detection, it is impossible to detect OLED display devices with good picture display quality but water or / oxygen has slowly infiltrated into the package cavity, that is, it is impossible to detect OLED display devices with good picture display quality but slight failure in the package, that is, When the above two methods are used to detect the packaging effect of OLED display devices, it is impossible to detect OLED display devices with insignificant packaging failure, which leads to a low factory pass rate of OLED display devices

Abstract

The invention discloses an OLED display device and a packaging effect maintenance method thereof, relates to the technical field of display, and aims at enhancing the ex-factory pass rate of the OLED display device. The OLED display device comprises an underlying substrate, an OLED device and a packaging structure. A packaging cavity is formed between the packaging structure and the underlying substrate. The OLED device is arranged in the packaging cavity. The OLED display device also comprises a detection part which is arranged in the packaging cavity. The chemical activity of the detection part for water or / and oxygen is the same with that of the OLED device for water or / and oxygen, or the chemical activity of the detection part for water or / and oxygen is the higher than that of the OLED device for water or / and oxygen. The OLED display device is used for displaying frames.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display device and a maintenance method for its encapsulation effect. Background technique [0002] Organic Light Emitting Diode (OLED) display devices have the characteristics of self-luminescence, high brightness, wide viewing angle, high contrast, flexibility, low energy consumption, etc. It is widely used in mobile phone screens, computer monitors, full-color TVs, etc. [0003] OLED display devices generally include a substrate, an OLED device, and a packaging structure. The OLED device is located on the substrate, and the packaging structure and the substrate together form a packaging cavity. The OLED device is packaged in the packaging cavity. Or / and water vapor is very sensitive, therefore, the encapsulation effect of the OLED display device is generally required to be relatively high. At present, during the production of OLED display devices, the encapsulation ...
