The new '2014 Sapphire Substrate Market Report' published by LEDinside, the green energy research department of TrendForce, a market research institution, points out that Apple's iWatch, which will be launched at the end of 2014, will have the opportunity to use sapphire cover. IWatch's sapphire cover is expected to reach of the sapphire market demand in 2014. If 2015 sales digital up to market optimistic prediction of 60 million a 2015 will accounted for sapphire substrate dosage of 27 and overall sapphire substrate of consumption total will is in 2014 will growth a times more than up to 129. The sapphire cover will likely be applied to APPLE wearable devices. According to the LEDinside survey, the AppleiWatch cover, which will be unveiled at the end of the year, will have the opportunity to import sapphire. Because the sapphire material has the characteristics of wear resistance and scratch resistance, the traditional boutique watches have been used for years. However, the market demand for hand-held application devices is quite large, which is far from the market size of traditional fine watches with only about 1 million watches per year. moreover, the sapphire long crystal process used in the traditional watch cover in the past has been unable to meet the huge market demand for hand-held applications. According to iWatch specifications, special sapphire crystal rods must be used to meet the requirements of subsequent processing design, which also explains why Appple needs to actively build the sapphire industry supply chain. The sales figures of iWatch will determine the supply and demand of sapphire substrate industry in 2015. It is understood that APPLE's first iWatch will have men's and women's watches. The watches will be fully equipped with sapphire watches, which are respectively men's 1. 66 and women's models 1. 33 '. Since iWatch was only launched at the end of 2014, if iWatch has a total demand of 5 million units in 2014, it is estimated that it will account for 6 sapphire market demand. As for 2015 of iWatch total shipments digital the opinions vary at present know to iWatch in 2015 season of stock quantity also up to the 13 Million A. If the sales situation exceeds expectations, the optimistic forecast in the market will have the opportunity to ship 60 million units. When overall sapphire cover of demand will accounted for sapphire substrate dosage of 27 and overall sapphire substrate of consumption total will is in 2014 will growth a times more than up to 129. Therefore, consumers' acceptance of iWatch will determine the important factor of whether the sapphire substrate industry will be tight in 2015.
