Abstract: A pixel definition layer and an OLED device are provided. The pixel definition layer includes a plurality of openings, the openings each being provided with bottom surface opening, a top surface opening and a side wall. The openings at least include a first opening defining a first pixel unit and a second opening defining a second pixel unit. The first opening is filled with a first pixel luminescent material, and the second opening is filled with a second pixel luminescent material. A decay rate of the first pixel luminescent material is lower than that of the second pixel luminescent material. The area of the bottom surface opening of the first opening is smaller than that of the bottom surface opening of the second opening. The side wall of the opening is provided with a pre-set reference surface. The pixel definition layer can be used for preparing an OLED device.

Abstract: An OLED substrate and a manufacturing method thereof, the OLED substrate includes a substrate, and an OLED device in a sub-pixel region on the substrate. The OLED device includes an organic layer having a non-uniform thickness. The OLED substrate further includes a transmittance adjusting layer in the sub-pixel region. The transmittance of a portion of the transmittance adjusting layer corresponding to a thicker portion of the organic layer is higher than the transmittance of a portion of the transmittance adjusting layer corresponding to a thinner portion of the organic layer. The transmittance adjusting layer is located on a light exit side of the organic layer such that light emitted from the organic layer passes through the transmittance adjusting layer when the OLED substrate is in operation.

Abstract: An organic light-emitting diode (OLED) component includes a substrate; a pixel defining layer and a plurality of first electrodes over the substrate; an insulating layer correspondingly disposed over the pixel defining layer; a first light-emitting layer over each first electrode; and a charge generation layer over the first light-emitting layer. The plurality of first electrodes are physically separated from one another by the pixel defining layer. The insulating layer is configured to facilitate manufacturing of the OLED component, such that after formation of the charge generation layer without a mask, portions thereof positionally corresponding to any two adjacent first electrodes are physically separated by the insulating layer. The OLED component can be a white light organic light-emitting diode (WOLED) component including at least one other light-emitting layer in addition to the first light-emitting layer.
