Light-emitting diode (LED) is an electroluminescent semiconductor device that is widely used in home and industrial lighting, outdoor displays,

automotive and mobile applications, and future refined displays (Mini-Led, Micro-Led) and other fields.

Continuously innovative solutions improve performance, reduce costs and enable new application areas in the coming years.

King Choice International provides LED chip companies with high-quality film-forming materials required for positive and negative electrodes,

including high-purity evaporation granules and sputtering targets, such as aluminum (Al), titanium (Ti), nickel (Ni), tungsten (W) ), tungsten titanium (WTi), and transparent conductive materials used for antireflection diffusions, such as ITO, IWO, etc.
