To deal with the price war South Korean manufacturers to develop new materials to grab the market

South Korea LED manufacturers in order to Chinese and competitive industry, Seoul semiconductor (Seoul Semiconductor) and LG Innotek to develop "Gan (gallium nitride, GaN") substrate, packaging and testing plant also intends to replace epoxy resin with silicone (Epoxy), strengthen product efficiency, prolong the service life.

Korean media reported on etnews 17, the current LED lighting on sapphire (Sapphire) substrate and silicon carbide (SiC) substrate, the Korean factory "study on Gan Gan substrate" (GaN-on-GaN), that can solve the problem of dislocation (dislocation). More than 10 years ago, Seoul semiconductor research and development, access to relevant patents, previously launched the nPola products, the brightness of 5-10 times higher than the current LED lighting, the company announced that it will soon be published more advanced than nPola.

LG Innotek also joined the research and development of this technology, but the high price of GaN, the company is still adjusting product launch time.

Packaging and testing plant, factory of Korea began to use silicon as packaging materials, replacing the epoxy resin. Epoxy resin using 3 thousand -6 after 1000 hours will appear color shift phenomenon, silicon use time more than 10 times, can be used for 30 thousand -5 hours. In addition, manufacturers are also developing cheaper materials than silicon.

Insiders said that the effectiveness of GaN and silicon are better than the existing material, the disadvantage is expensive, to increase market competitiveness, we must also depress prices, improve performance.

Japanese media, industry news reported on July 11th, Toshiba (Toshiba) plans this year (2014) the official mass production of white LED products, the target for the monthly production capacity significantly amplified 150 times to the present.

Toshiba produced by the company with the white LED white LED (Bridgelux; Dachang Puri TSMC (2330) investment company) jointly developed the "GaN-on-Si" component of LED, and compared to existing components using LED sapphire wafer has more competitive price. Toshiba and in April 2013 acquired the GaN-on-Silicon technology related to the white LED chip related assets.
