How To Handle Apple iPhone Screen Cracks And Touchscreen Malfunctions

If your iPhone’s screen cracks, you might encounter some issues and it could also stop working all together. It can be a relationship between a crack and a screen malfunction, but it can also be a coincidence that the screen doesn’t function. Alternative issues may cause the malfunctions. It is possible that a crack interrupts the electrical signals if it reaches a specific layer. You should know that the touch screen contains multiple layers.

The iPhone has a screen that is durable and scratch-resistant. That is possible grace to the glass, used also at the windshields of helicopters and high-speed trains. The fingerprints are no more an issue because it is resistant to oily grime, on the diagonal of 3.5 inches. That feature is called “oleophobic”. Another ability that the screen has is the impressive resolution of 326 pixels per inch. That means that the images will be clear even if you will use zoom in option while taking pictures. The in-plane switching technology will help the picture to keep its clarity no mater the angle that it’s taken from.

When using an iPhone you will notice that its screen provides navigation and control options, not only showing images. That ability isn’t found on others displays. In order to open a program or make some setting changes, the user has to type on virtual buttons instead of physical ones. If you choose to zoom in or out on any page, just make a pinching motion and if you want to access a new material, swipe the screen. You will notice that the screen doesn’t work if using gloves or a stylus. That is because it works by transmitting changes in electrical conductivity. The fingertips have electrical charge that is detected when you touch the screen.

The layers from what the Apple iPhone screen is made of are: the protective glass, the digitizer and the Liquid Crystal Display, know as the LCD. The protective glass has the protection role, the digitizer is the one that detects the electrical current and the LCD is the one that displays the images. The applications on the home screen are displayed by that last layer. If the protective glass is cracked it shouldn’t affect the functionality of the screen. We couldn’t say the same thing if the layers that are affected are the digitizer or the LCD. That is the case when the screen will no longer work, when the crack damages one of these two layers.

You should consider that there are some alternative issues before replacing the screen. That way, make sure that the screen isn’t dirty or that there is no protective shield interfering with the detector. Another possibility is to reset the phone. In order to do that, make sure you press and hold the “Sleep/Wake” and”Home” buttons. When the Apple logo appears it is alright to release those buttons and the problem should be fixed, only if it is a software-related one. If after all that, the screen remains blank consider the possibility to replace it. You will simply have to go to a local Apple Store and the screen issue will be quickly solved. If you will choose to do the replacement yourself, make sure that you have purchased the correct size and that you have a kit that contains all the necessary parts.
