  • Patent number: 11552248
    Abstract: An organic light emitting device and a method of manufacturing the same are provided. The organic light emitting device, from bottom to top, includes a substrate, an indium tin oxide layer, a semiconductor layer, and a pixel defining layer. The semiconductor layer covers foreign particles on the indium tin oxide layer to make the indium tin oxide layer have an even thickness. The method of manufacturing the organic light emitting device including steps of providing an indium tin oxide layer, providing a semiconductor layer, patterning, and providing a pixel defining layer. The disclosure prevents from uneven brightness (mura) causing from a bright spot or a dark spot appearing at the foreign particles and ensures an overall even brightness of the organic light emitting device by providing the semiconductor layer disposed on the indium tin oxide layer to cover foreign particles on the indium tin oxide layer.

  • Patent number: 11289554
    Abstract: The present invention provides an organic light emitting device and a fabricating method thereof. The organic light emitting device includes a thin film transistor substrate, a pixel defining layer, a reflective electrode layer, and a plurality of sub-pixels. The pixel defining layer is disposed on the thin film transistor substrate and includes a plurality of via holes; and the plurality of sub-pixels are disposed in the via holes correspondingly. A thin film stand layer is disposed on the thin film transistor substrate and corresponds to a portion of the via holes, causing a reduction in a depth of the portion of the via holes, and a depth of another portion of the via holes is greater than the depth of the portion of the via holes.
