Firstly, you need to understand the difference between screen glass and LCD. This is especially important when making decisions about the type of repair you want for your device.
|
|
|
Two parts make up the front display panel: the screen glass and LCD.
|
|
|
|

|
|
Screen glass is a protective layer placed on the LCD to protect it from scratches, dust, and other forms of damage. (also commonly referred to as the “screen”, "glass" or “digitizer”).
It also reduces glare and reflection, making the screen image clearer.
Screen glass is usually made of tempered glass or plastic and comes in various thicknesses.
|
|
|
Damage to the screen glass
|
|
In the event a damage is done to the screen glass, if the impact is not too great, only the glass will be broken or chipped off.
The LCD, which is beneath the glass screen, will be protected from further damage. The LCD will still function and no unusual distortions is seen on it.

LCD panel of iPhone
|
|
LCD, which stands for Liquid Crystal Display, is a type of display technology that uses liquid crystals to create the image on the screen. (commonly referred to simply as “LCD” or “LED” or “OLED”).
It is made up of many small pixels arranged in a grid. Every pixel has three subpixels used to create the screen colours.
LCDs are found in a range of products, from televisions to smartphones, and they are known for their bright, sharp images and low power consumption.

|
Damage to LCD and glass
|
|
The display is the most fragile part of the phone. It covers almost the entire front panel of the iPhone.
Though Apple has improved its glass durability over time, it is still susceptible to cracking when dropped or hit by heavy objects.
Following are some of the signs to look out for if you suspect your iPhone is having issues with its display.
|
|
|
|
Tinted or yellowish screen is common for iPhone with extensive usage
|
|
If you notice that your iPhone's screen is discoloured or has a yellowish tint, it's time to replace the screen.
This could be a sign of water damage or other internal problems, and it could also be a sign that your phone has overheated.
|
|
|
|
Horizontal or vertical lines on LCD
|
|
If you notice lines on your iPhone's screen, this could be a sign that the screen's internal components have been damaged.
There are small transistors and wiring internally and one of these could be malfunctioning.
|
|
|
Blacked out or blank display
|
|
|
|
Part of display blacked out
|
|
|
You can hear the chime sound when the iPhone is turned on, but the display is blank. Or a section of the LCD is blacked out and unresponsive.
|
|
|
Touchscreen is unresponsive
|
|
If you notice that the touchscreen is not responding to your touch, the LCD is likely faulty.
Additionally, if the touchscreen is slow to respond or unresponsive in certain places, this can also signify a broken LCD.
|
|
|
Black spots or dead pixels
|
|
|
|
Apple
|
|
Dead pixels are small areas of the LCD that do not display images or text.
To check for dead pixels, set the phone background to Red, Green and Blue.
If you notice any unusual spots on these backgrounds, it indicates the pixel on the display has burned out.
|
|
If the phone's screen is hot to the touch, it could be a sign that something is wrong with the internal components.
This could be a sign of a battery or processor issue, which needs to be checked as soon as possible to prevent further damage to the LCD.
|
|
|
|
Screen flickering on and off
|
|
|
If your iPhone's screen starts flickering or has a "static" effect, the LCD is highly unstable and need replacement.
