SMD LED display were composed by SMD LED lamps. SMD LED lamps is short for “Surface Mounting Device”
SMD LED display is more and more popular since the Advantages of perfect: color blending capability, no color shift at extreme angles, much wider viewing angle comparing to DIP. More important reason why SMD is more popular is the resolution of SMD LED display is much higher than DIP LED display. For example, the smallest pixel for DIP LED display is 10mm. However, the smallest pixel pitch for SMD LED display is 3.2mm which means 9 times resolution higher than DIP LED displays. Furthermore, the SMD LED display is more energy saving and cost is also lower than DIP LED display
According to the SMD LED’s encapsulation size, SMD LED can be classified to several models, like: 0606, SMD0808, SMD0909, SMD1010, SMD1515, SMD 2020, SMD2121, SMD3528, SMD1921, SMD2525, SMD2727, SMD3535, SMD5050 SMD etc
SMD 1921, 2525, 2727, 3535, 5050 is used for outdoor waterproof models, others is used for indoor non-waterproof models.
According to the SMD LED’s encapsulation color:, SMD LED can be classified to Black LED lamps and white LEDs.
