Beginning with the iPhone 4, Apple moved to an assembly that includes the iPhone LCD, the iPhone digitiser and also the outer glass which is assembled with the factory. This was an improvement within the previous models of iPhone 3 and 3GS which had challenge with dust getting under the glass simply because they were not “fused” together in the clean room environment to avoid dust particles from being trapped involving the layers.
Here are various references:
LCD: The LCD is usually a Liquid Crystal Display which is backlit and it is the flat, thin technology that really “displays” the pictures in your device. This is exactly what you “see” when you are exploring the phone.
DIGITISER: The digitiser is an extremely thin transparent layer sandwiched involving the LCD and also the Glass. It is the component the senses your “touch” and responds to clicking, zooming and selecting on the phone.
GLASS: This can be the glass, the outer piece that protects the digitiser with the elements. It is simply that…a kind fitted custom piece of glass which is made only for your device.
For the reason that LCD is really what actually displays the images, pictures, webpage, etc…If you have dropped your phone and can no more see anything on the screen, that’s probably because it includes a bad LCD. It may be verified if the screen has lines within it, or if it has a “spilled ink” look. Many customers with broken LCD’s report that there’s ink inside the screen…this can be 100% damage LCD. Remember that the LCD is under the digitiser and also the glass…so probably these two items can be damaged as well if the LCD is also damaged.
We’ve also seen bad LCD’s when you are able still see every one of the images, but the screen is extremely DIM. This may indicate a damaged backlight (which can be part of the assembly) and therefore will need a replacement. There may be lots of confusion when it comes to LCD, Digitiser and Glass assemblies vs. Glass Assemblies as well. There can be devices that also use a separate glass piece rather than a “fused” assembly such as the iPhone as stated above. The Android lines are a mix-and-match where many of them are full assemblies and some have separate glass panels which can be replaced individually. If you send in an iPhone 5 for and LCD replacement, you will positively get a brand new LCD, digitiser and glass panel – simply because they are full assemblies. Likewise, you’re going to get all 3 parts replaced if you just have a cracked glass. Again, simply because come pre-assembled as assemblies.
Reports on the iPhone 5’s anodised aluminum casing getting scratched and scuffed quickly started to emerge quite quickly after the launch. A number of people found the coating was easily scratched off across the edges and chipped for the back panel, revealing the silver aluminum beneath. There were also reports of iPhone 5 units being scratched away from the box. A few complaints have come in that the iPhone 5 touch screen is randomly dropping touch input when a finger is dragged forwards and backwards diagonally across the display. Some people have even reported a completely unresponsive touch screen or even the screen going blank for a few seconds. There have also been complaints about the touch screen registering touches after the user hasn’t touched that section of the display. While this doesn’t seem to be an extensive issue it is clearly a pretty extreme problem. There could be more than one issue here, some tests suggest the quick swipe failure is an iOS issue, but the more serious unresponsive or wrongly registering touches problems are likely to be hardware related.
When your problem is severe then take your iPhone 5 to an Apple store and prove to them the difficulty and you’ll get a replacement. You could try resetting or restoring your iPhone 5, but this is most likely a hardware problem and you shouldn’t have any trouble finding a replacement. When your smashed, cracked, damaged and broken iPhone LCD screen assemblies are here, it’s usually best to translate “Original” and “Non-Original” to “Never Repaired or Refurbished” or “Has been Repaired or Refurbished” for easier understanding.
