The invention discloses a high-reliability plug-in type light-emitting diode with a built-in driving IC, and belongs to the field of diodes, the high-reliability plug-in type light-emitting diode with the built-in driving IC comprises a built-in IC control chip, a lead frame and a light-emitting chip, the lead frame comprises five functional welding pins, and the five welding pins are respectively DO, Gnd, Vcc, DI1 and DI2. The DO contains DO1 and DO2; the built-in IC control chip is used for processing data signals of the controller and a superior pixel point; the light-emitting chip is used for radiating visible light; the DO is used for outputting a data signal; and the Gnd and the Vcc are respectively a positive electrode and a negative electrode. Normal operation of the pixel points is guaranteed, meanwhile, double-path signal transmission is adopted, operation of the secondary pixel points is not affected after a single pixel point is damaged, normal display of the whole color is guaranteed, the use reliability is higher, the market use requirement is met, the maintenance probability is reduced, and the high-reliability plug-in type light-emitting diode is suitable for application and popularization.
