(2) At present, the nonmetallic materials that can be used as mobile phone casings usually include polycarbonate (plastic, which is commonly used in functional machines and has been eliminated), glass (the glass casing of iPhone4 proves that this technology is feasible), ceramics (the output of millet ceramic mobile phones is not high), carbon fiber (the cost is too high) and so on. Because of its material, handle and formability, glass is the most likely material to be used first among nonmetallic materials at present.
(3) With the wide application of flexible organic light-emitting diodes, the cover glass needs to be made into 3D shape, and the back glass needs to be upgraded to 3D glass based on the requirements of grip and aesthetics.
As the industry vane, both Apple and Samsung use double-sided 3D glass, which will inevitably drive other brands of mobile phones to follow up quickly. Some analysts believe that the permeability of 3D glass will reach 40% in 2065438+2008, and the corresponding market size should be in the order of hundreds of billions in terms of single-sided 3D glass 75 yuan. Since 3D glass is so sought after by the market, let's analyze the patent layout in the field of domestic 3D glass, from which we may find out which one is really powerful.
