Abstract

The invention provides an OLED device and a manufacturing method thereof. The OLED device includes a substrate and a plurality of pixel units on the substrate. Each of the pixel units includes a first electrode layer, an organic layer, and a second electrode layer. The OLED device is characterized by comprising a micro-cavity effect adjusting structure including at least one transparent oxide layer disposed between the first electrode layer and the organic layer. The OLED device and the manufacturing method thereof add a way of adjusting the total optical path difference in optical design so as to improve adjustment flexibility.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED device and a manufacturing method thereof. Background technique [0002] Large-size OLED display technology has become a favored technology for large-size high-end TV applications because of its strong dark-state expressiveness and high contrast ratio. However, due to the limitations of OLED material costs and process yields, its market share is not high. Although the large-size OLED display processed by the solution method is expected to greatly reduce the manufacturing cost by depositing OLED ink materials through inkjet printing technology, but the current bottom emission printed OLED display devices have low aperture ratio, poor luminous efficiency, and small color reproduction range. , short lifespan and other limitations, so top-emitting OLED display devices that can technically solve these limitations have attracted a lot of research and development interest, and ...
