Abstract
An OLED display device and a method for detecting and repairing packaging effects of the same are disclosed in order to improve the production yield of OLED display devices, which relate to the field of display technologies. The OLED display device includes a substrate, an OLED element and a packaging structure, a packaging cavity being formed between the packaging structure and the substrate, the OLED element being located within the packaging cavity. The OLED display device further includes a detection unit, the detection unit being located within the packaging cavity and having a chemical activity for oxygen not lower than that of the OLED element.
Claims19
An OLED display device comprising a substrate, an OLED element and a packaging structure,
- wherein a packaging cavity is formed between the packaging structure and the substrate, and the OLED element is located in the packaging cavity,
- wherein the OLED display device further comprises a detection unit, the detection unit being located in the packaging cavity and having a chemical activity for oxygen higher than that of the OLED element, so as to estimate a packaging effect of the OLED display device through determining whether the detection unit is eroded,
- wherein the OLED display device comprises a display region and a non-display region surrounding the display region,
- wherein a repair unit is arranged in the non-display region and configured for repairing the packaging structure upon detection of a packaging failure of the OLED display device by the detection unit.
