  • Patent number: 8987750
    Abstract: A LED chip packaging structure, its manufacturing method, and a display device are disclosed. A conductive unit is formed at two opposite sides of a LED chip unit, and comprises a first conductive layer formed at a side of, and electrically connected to, a first electrode, a second conductive layer formed at a side of, and electrically connected to, a second electrode, and an intermediate isolation layer formed at a side of a GaN layer. The LED chip unit and the conductive unit are connected laterally to form an electrical-connection channel as a whole, without welding a gold wire for the conductive channel as in a traditional LED. Thus, the method is able to reduce the total thickness of the LED chip device, increase the thermal conductivity effect of the LED chip and the overall stability, and improve the light-extraction effect of the surface of the LED chip.
