A LED package structure is provided. The LED package includes a three-element red-green-blue (RGB) light emitting diode (LED). The carrier of the LED package has a power input pin and a ground pin and the pins form extension portions inside the carrier. The driver element, a red dice, a green dice, and a blue dice are disposed within the carrier. The driver element controls the red, green and blue LED dices by receiving an operation power and a PWM (Pulse Width Modulation) signal from the power input pin. By this arrangement, the LED package with compact structure, good mixing effect, and high resolution is achieved. Furthermore, the using space is saved and the PIN number is reduced to allow mass production with low costs. |
