摘要： A highly stable organic light-emitting panel includes a substrate and a plurality of pixelated OLED circuit assemblies. The substrate further includes an auxiliary electrode and a plurality of circuit protection structures, each of which is electrically connected to a corresponding pixelated first electrode in each pixelated OLED circuit assembly. The plurality of circuit protection structures are respectively connected to the auxiliary electrode. An insulator covers the auxiliary electrode, the plurality of circuit protection structures, and an area between the plurality of circuit protection structures and the plurality of OLED circuit assemblies. When a current passing through a pixel with short-circuit defect in any one of the plurality of OLED circuit assemblies is greater than a predetermined threshold of the circuit protection structure, the circuit protection structure corresponding to the pixel with short-circuit defect fuses, thereby isolating the OLED circuit assembly corresponding to the pixel with short-circuit defect.
