But what we want to discuss today is Epistar and Silan.

A lot of LED display factories in Shenzhen adopts this LED chips configuration (Epistar (Red) + Silan (Green, Blue) is because:
1. Epistar company is focus on manufacturing Red led chips for years. Quality is better than Silan.
2. About Green and Blue LED chip, Silan can produce the chips in the same wavelength and the same chip size to Epistar.

The only different between Epistar Green and Blue chips and Silan Green and Blue chips is, in the first half year, Epistar can show a better color and higher brightness on the screen. But after half a year, The decay of the lights makes them become the same quality.
