Abstract: A mask is provided. The mask is applicable to prepare an organic functional layer of a sub-pixel in a display panel. The display panel includes a plurality of pixel units and a pixel defining layer, wherein each pixel unit includes a plurality of sub-pixels, and the pixel defining layer surrounds each sub-pixel. The mask includes a substrate and at least one photo spacer, wherein the substrate includes an opening region and a light shielding region. The opening region exposes a light emitting region of part of the sub-pixels, and the light shielding region covers the remaining sub-pixels and the pixel defining layer. The photo spacer is disposed in the light shielding region.

Abstract: An organic light emitting device, a preparation method therefor, and a display apparatus are provided. The organic light emitting device includes an anode, a cathode, and a light emitting layer and an electron transport layer arranged between the anode and the cathode. The electron transport layer is arranged between the light emitting layer and the cathode. The electron transport layer includes a first host material and a second host material. A mixing ratio of the first host material to the second host material of one side of the electron transport layer close to the light emitting layer is different from a mixing ratio of the first host material to the second host material of one side of the electron transport layer away from the light emitting layer.
