the distinction is
1, the structure of raw materials is different: the chip is the main raw material of LED, and the chip can emit light freely; A chip is a solid-state semiconductor device, a P-N junction, that converts electricity directly into light.
2, the composition is different: the composition of the chip: to have arsenic, aluminum, gallium, indium, phosphorus, nitrogen, strontium several of these elements; The composition of the chip: by the gold pad, P pole, N pole, PN junction, back gold layer (double pad chip without back gold layer) composed.
3, the classification is different: the chip can be classified according to the luminous brightness, composition elements; Chips can be classified according to purpose, color, shape, and size.
