1. A self-lit display panel comprising:
a first substrate;
a photonic integrated circuit (PIC) layer supported by the first substrate, the PIC layer comprising an array of waveguides for guiding illuminating light;
an electronic circuitry layer supported by the PIC layer; and
a pixelated electrode layer comprising an array of pixel electrodes, wherein the electronic circuitry layer is configured for applying electrical signals to the array of pixel electrodes;
wherein the PIC layer comprises an array of out-couplers coupled to the array of waveguides for out-coupling portions of the illuminating light through the electronic circuitry layer and through the array of pixel electrodes.
