The alkali-aluminosilicate sheet glass is used primarily as cover glass for portable electronic devices, including mobile phones, smartwatches, portable media players, portable computer displays, and television screens. It is manufactured in Harrodsburg, Kentucky; in Asan, South Korea; and in Taiwan.
According to internal info, Apple procured 82% of panels from Samsung, 12% from the Korean company LG Display and the other 6% from the Chinese BOE.
The LCD (or Liquid Crystal Display) screen is entirely responsible for the display and touch-response function of your device. So which screen is broken? Most of the time, the damage to your screen will be pretty obvious. You`ll see the spider web patterns of shattered glass across the front of your iPhone.
Screen repair

We replace cracked screens for a fee. Accidental damage isn`t covered by the Apple warranty. Screen repairs are eligible for coverage for accidental damage from handling with your AppleCare+.

You can also dial *#*#0*#*#* to test the LCD screen or *#*#2664#*#* for a touch-screen test. However, you either need a third-party app, remote help, or extensive Apple Customer Support assistance for an iPhone. Let`s review the different ways to run an iPhone hardware test.
The LCD color filters are made with a photolithography process on large glass sheets that are later glued with other glass sheets containing a thin-film transistor (TFT) array, spacers and liquid crystal, creating several color LCDs that are then cut from one another and laminated with polarizer sheets.
An Unknown Part message will appear if the display installation is incomplete or if the display: Was replaced with a nongenuine display. Was already used or installed in another iPhone. Isn`t functioning as expected.
The Retina display is a branded series of IPS LCD and OLED displays by Apple Inc. and have a higher pixel density than its traditional displays.
In short, LCDs are lit by a backlight, and pixels are switched on and off electronically while using liquid crystals to rotate polarized light. A polarizing glass filter is placed in front and behind all the pixels, the front filter is placed at 90 degrees.
If you crack your phone screen and do not fix it immediately, you could damage your LCD. Dust can also seep through the cracks on the screen and cause LCD screen damage. Water or liquid damage: If you drop your phone into water or some other liquid, some of it could seep into the phone and damage the LCD screen.
Generally, if the damage is minor, the repair is affordable and easy, and the display is still under warranty or insurance, you should repair it. However, if the damage is major, the repair is expensive and difficult, and the display is out of warranty or insurance, it may be best to replace it.
On average, iPhone screen repairs cost $220.

If you have a warranty, prices start at $29 but can increase to $329 if you don`t have one.

The basic display using liquid crystals is composed of six main components: a polarizing filter, a glass plate that has a transparent electrode pattern, the liquid crystal material, a clear common electrode on glass, a polarizer whose axis is crossed compared to the first polarizer, and either a reflective surface or a …
LCD screens can be grouped into three categories: TN (twisted nematic), IPS (in-plane switching), and VA (Vertical Alignment). Each of these screen types has its own unique qualities, almost all of them having to do with how images appear across the various screen types.
1. An LCD consists of a thin layer, of 5–10 μm thickness, of liquid crystal material, confined between two glass substrates coated with a transparent conductor which has been selectively etched using standard techniques to produce the desired electrode pattern.
LCDs are another display technology used for smartphones, and this year DisplayMate testing proves that Apple`s iPhone 7 and 7 Plus have the best LCDs it has ever tested. The Apple iPhone 7 and 7 Plus have the same display size and resolution as we have seen on these two models for years.
Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen.
One of the most important differences between an original and a “copy” screen is how the digitizer (touch sensor) is designed. Apple has it manufactured as part of the LCD itself, whereas the copies have it on the glass.
Long story short, if “Unknown Part” appears, the component is likely to have been replaced by a new one that will work as well as an original one. And even if something did go wrong, your device is always under warranty for any defective issue.

OEM Screens

OEM screens are the original screen that came on the phone when it was new. To spot an OEM screen:- Check to make sure the touch flex is not connected to the glass. In the top left-hand corner there is a black sticker over the 3d barcode.

LCD stands for Liquid Crystal Display. OLED stands for Organic Light-Emitting Diode. OLED is a newer, more advanced technology which offers superior quality and performance to LCD. OLED screens have better contrast, higher brightness, fuller viewing angle, wider colour range and faster refresh rates.

Liquid crystal display explained

Both types of displays use liquid crystals to help create an image. The difference is in the backlights. While a standard LCD monitor uses fluorescent backlights, an LED monitor uses light-emitting diodes for backlights.
