The evolution of mobile phone case is accompanied by the evolution of mobile phone. From the era of NOKIA functional machines to the era of Apple, HUAWEI and other smart machines, mobile phone cases are facing many opportunities and challenges. But every time it overcame difficulties and developed at a high speed, it seemed like a vivid history of struggle.
Before 2008, all mobile phones in the world were owned by NOKIA. The market share of NOKIA reached 40%. But now we look at this kind of mobile phone, which is called a function machine.
The so-called function machine means that people can only use it for basic functions. These functions are make phone calls and send and receive short messages. Each function is put together separately. The underlying program has basically been written to death. There is no such thing as intelligent interaction and various APP. And this kind of mobile phone is strong and durable. At most, the mobile phones at that time were covered with a layer of plastic protector when they left the factory. This protector s similar to the kind of plastic wrap. And at that time, no one can stick the protector.
But then everyone began to relate to the beauty of the screen. After all, it is strange that people who scratch around on their mobile phones. So we began to fear that the screen was dirty and there were scratches on the screen. We pasted the “PET protector” at that time. But this kind of protector is thin and not scratch resistant. Sometimes when you put it in your pocket, you may be scratched by the key. If you stick this kind of protector, you have to change it frequently. It is annoying.
Apple 4 used front and rear tempered glass for the first time in mobile phones. The resolution reached more than 4 times that of the computer at that time. It surpassed the human retina. At that time, it seemed to be extremely ultra-high definition. How can you bear to let such a beautiful screen get hurt?
As a result, the number of users of PET plastic protectors has increased rapidly. But its shortcomings are revealed. Plastic protector is too durable, easy to get hurt. In particular, plastic protector can't be an explosion-proof screen. So we need to get a very hard layer to protect our beloved mobile phone.
The term toughened protector has entered everyone's eyes. Toughened protector has excellent performance. It stole the limelight of PET plastic protector and sold well. But the curved screen with rounded edges came out again. Manufacturers have racked their brains. The most direct idea is, of course, how to bend the screen and how to bend the toughened protector. This simple idea led to the birth of 3D toughened protector.
