Most of our repairs are screen replacements, and this is due to the fragile glass that is used for smartphones and tablets. Lots of customers ask us, “Why they are so easy to break?” Why they don't invent unbreakable screens? The screen of the smartphones is so easy to break because the big producers use normal glass, which allows them to sell smartphones at an affordable price. investing in other type of screen increases the production costs of a smartphone, therefore, iPhones, Samsung, HTC or other smartphones won’t be accessible for everyone! There are a number of articles and discussions on this topic, discussing Gorilla Glass (used by Apple, Samsung and others), OLED and the newer Sapphire Glass. Which one is the best and why? Well, Apple started to include Gorilla Glass on its iPhones from the beginning. The idea started a year earlier, when Steve Jobs discussed with CEO of Corning Inc., Wendell Weeks, about a joint development. So Corning factory developed the screens for iPhones and other smartphones, as well as other consumer electronic devices for other companies. OLED (Organic Light Emitting Diodes) defines solid-state devices composed of thin films of organic molecules that create light with the application of electricity. OLEDs can provide brighter, crisper displays on electronic devices and it was used on HTC Desire, Samsung Jet and Nokia N86. The most recent innovation in terms of screen types for smartphones is mentioned in an article posted on CNET website. The new kind of screen is called Sapphire Glass and is made from sapphire, actually not from sapphires mined from the ground, but is synthetically grown from a "mother" or starter crystal, companies that manufacture synthetic sapphire melt and cut the material into wafers, sheets, you name it. So is created and manufactured in the laboratory. This screen seems like it's made of glass, because is not different from one, but it isn't glass for sure! Depending on the exact formula of chemically reinforced glass, sapphire has approximately 2.5 or 3 times its strength. In terms of the pricing, the material is more expensive, about three or four times the cost of current glass screens. So I guess now is clear why they don’t use it for smartphone screens yet. But manufacturing prices continue to drop, so maybe in few years we will use them as we use glass today. If you want to see more about this, watch out this video with a demonstration: The company that organized the sapphire display demo GT Advanced Technologies, manufactures giant blocks of crystalline sapphire that customers can then turn into phone screens, TV leds or something else. It takes 16 days and 2,200 Celsius degrees to create a 250-pound block of synthetic sapphire. Today there is no possibility to create sapphire displays for so much request, but who knows what will happen in the future? How much are you willing to pay for an unbreakable iPhone screen?
