1. A method of manufacturing a self-lit display panel, the method comprising:
forming a photonic integrated circuit (PIC) layer comprising an array of waveguides for guiding illuminating light and an array of out-couplers coupled to the array of waveguides for out-coupling portions of the illuminating light;
forming an electronic circuitry layer comprising a pixelated electrode layer comprising an array of pixel electrodes; and
disposing the PIC layer relative to the electronic circuitry layer such that in operation, the illuminating light portions propagate through the array of pixel electrodes.
