1. The touch-screen, officially named the Digitizer, is the part of your baby that you stroke, the shiny and silky piece of glass that immediately recognizes your finger. The touch-screen is an electronic visual display that the user controls through multi-touch or simple gestures. By simply touching its screen with a special pen the touch-screen allows the user to directly interact with what is displayed, without using a touchpad, mouse or any other kind of intermediate device. Touch-screens are common in devices such as tablets, computers, game consoles, and your iPhone 5. iPhone 5s LCD replacement also play a prominent role in digital appliance design, as satellite navigation devices, video games, mobile phones and even some books.
The touch-screen is the top glass of your iPhone 5S.
2. The liquid crystal display, also known as LCD, is the display that shows you your “selfies” made with your girlfriend and the games you play. The LCD is directly located under the touch-screen. It is a letters, numbers and images display device. It consists of an array of liquid cells that become opaque or change color under the influence of an electrical field. The physical phenomenon is explained by the property of liquid crystals that influence the polarization direction of the light when they are put under a certain level of voltage. The crystals display themselves and do not produce light, and they have very low energy consumption. An LCD display is electronically controlled by a decoder of numerical and alphabetical characters. Here is a great explanation of how LCD’s work.
What happens most of the time when you drop your iPhone 5S is that your iPhone 5s LCD glass shatters, so that means that your baby might still be alive, but it is not going to “breathe” very well. OK, so now that we have cleared some of the foggy clouds, let’s bring in the more difficult parts.
Both the LCD screen and the touch-screen on the iPhone 5S have been fused together during the manufacturing process and the iPhone 4’s screen design was also the same.
