Embodiment Construction

[0041] The present invention will be described in detail below with reference to the specific embodiments shown in the drawings. It is worth noting that the embodiments described below do not limit the present invention, and the structural, method, or functional transformations made by those skilled in the art based on these embodiments are all included in the protection scope of the present invention.

[0042] Please refer Figure 1 to Figure 6 Shown are three embodiments of the OLED device 100, 100', 100" of the present invention, including a substrate 1, a light-emitting element disposed on the substrate 1, and a packaging cover 91. The light-emitting element includes a first electrode layer and a second electrode layer. The electrode layer and the light-emitting layer 7 located between the first and second electrode layers. In the described embodiment, the first electrode layer is the anode layer 5 and is located below the light-emitting layer 7, and the second electrode layer...

Abstract

The invention relates to an OLED device and a method of the OLED device. The OLED device comprises a substrate, a light emitting element on the substrate and a packaging cover, the light emitting element comprises a first electrode layer, a second electrode layer and a light emitting layer between the first electrode layer and the second electrode layer, and an inorganic pixel limiting layer used for sealing the light emitting element between the first electrode layer and the second electrode layer is arranged around the light emitting element. The inorganic pixel limiting layer is closely attached to the first electrode layer and the second electrode layer. Through the arrangement, the light emitting layer is surrounded in internal inorganic layer closed space, the capacity of blocking moisture and oxygen can be improved, and therefore the packaging effect is improved, and the structure is simple.

Description

Technical field [0001] The invention relates to the field of packaging technology, and specifically designs an OLED device and a method thereof. Background technique [0002] Organic light emitting diodes (Organic Light Emitting Diode, OLED) have excellent performance and wide application, but because of the material properties, they are easily deteriorated after being attacked by water vapor and oxygen, so the packaging performance is very demanding. Traditional glass cover or metal cover packaging has achieved good results, but it is not completely suitable for some important or potential applications, such as top-emitting OLED display technology, flexible OLED display technology, or flexible OPV. For this reason, the industry has developed a thin-film packaging technology, which uses one or several layers of vacuum-deposited thin films to block water vapor and oxygen, does not block the path of light emission or incidence, and does not affect the flexibility of the substrate. ...
