Recently, Crystal Optoelectronics said that the sapphire substrate has the advantage of mature industrial chain and relatively reasonable cost, and there is no risk of being replaced by silicon substrate technology.
Some investors inquired about the negative impact of silicon substrate technology on the company. Crystal Optoelectronics said that silicon substrate production technology is difficult and expensive, and it is currently only used for high-end products of some high-power lighting chips.
Crystal Optoelectronics is mainly engaged in the production, processing and sales of precision optical film components, sapphire substrates (including PSS) and micro projection modules.
