What is the market situation and application scope of LED chip lamp beads? SMD LED is mainly used in lighting system, decoration, electronic equipment indicator, backlight, display, apparatus and other fields. In 2009, the decrease in the production of mobile phones and LCD TVs may affect the supply expectation of such components. The package sizes of conventional monochrome SMD LEDs are 1206 (3215), 1004 (2510), 0805 (2012) and 0603 (1608).

The small size provided by Chinese manufacturers is 0603, and the thickness is only 0.3mm. The smaller LED with size 0402 (1005) is still in trial production.

In addition, Chinese suppliers also provide bi color and tri color products with mature technology but low profits, which are mostly used in backlights, appliances, household products, consumer electronics and displays. Despite low market demand, manufacturers continue to provide sideview SMD LEDs, including 335 (4008), 020 (3806) and 215 (2810).

With the good expectation of the market for the future status of SMD LED, major mainstream manufacturers have launched their own SMD LED development plans and prototype products. For a while, the SMD LED market presented a lively atmosphere of prosperity and contention.
