An organic light-emitting device, a preparation method, and a display panel are disclosed. The organic light-emitting device is formed on a glass substrate. The organic light-emitting device includes a first electrode, a second electrode, and an organic light-emitting layer disposed between the second and the first electrode. A first light extraction layer is disposed between the first electrode and the glass substrate. The first light extraction layer is formed by dielectric nanoparticles. The side of the first light extraction layer facing towards the organic light-emitting layer has a relatively rough surface. Light is extracted from the organic light-emitting layer by the dielectric nanoparticles. The rough surface formed by the dielectric nanoparticles has a relatively greater ability to scatter more light. The dielectric nanoparticles are inserted into the glass substrate and extract light captured in the organic light-emitting layer, thus improving the light extraction efficiency of the organic light-emitting device.

An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different print head/substrate scan offsets, offsets between print heads, the use of different nozzle drive waveforms, and/or other techniques. Optionally, patterns of fill variation can be introduced so as to mitigate observable line effects in a finished display device. The disclosed techniques have many other possible applications.
