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.
