Understanding Screen Components

To comprehend the differences between cracked glass and broken LCD screens, it’s essential to understand the basic components of a mobile phone screen. Most modern smartphones consist of three primary layers:

Cracked Glass

What is Cracked Glass?

Cracked glass refers to damage that affects only the outer glass layer of the phone screen. This type of damage can range from minor hairline cracks to extensive shattering. Despite the cracks, the touch functionality and display may still work perfectly if the underlying digitizer and LCD screen are intact.

Repairing Cracked Glass:

Repairing cracked glass typically involves replacing the glass layer while keeping the digitizer and LCD screen intact. This process can be relatively straightforward and cost-effective if the damage is limited to the glass.

Broken LCD Screen

What is a Broken LCD Screen?

A broken LCD screen refers to damage that affects the inner display layer, specifically the LCD or OLED screen. This type of damage can result in various display issues, including black spots, coloured lines, screen flickering, or a completely blank screen. A broken LCD screen can also impact touch functionality if the digitizer is affected.

Repairing a broken LCD screen involves replacing the entire display assembly, which includes the glass layer, digitizer, and LCD screen. This repair is more complex and costly than replacing just the glass.

Frequently Asked Questions about cracked glass and broken LCDs

1. How can I tell if my phone has a cracked glass or a broken LCD screen?

Look for visible cracks on the screen’s surface. If the display and touch functionality are still working correctly, you likely have a cracked glass. If you see black spots, coloured lines, or experience touch issues, you probably have a broken LCD screen.

2. Can I continue using my phone with a cracked glass?

Yes, you can continue using your phone with a cracked glass if the display and touch functionality are unaffected. However, it’s advisable to get the glass replaced to prevent further damage and maintain the phone’s appearance.

3. How much does it cost to repair a cracked glass versus a broken LCD screen?

Repairing a cracked glass is generally less expensive than repairing a broken LCD screen. The cost can vary depending on the phone model and the repair service provider. Replacing a broken LCD screen involves more components and labour, making it costlier.

4. Can I repair the cracked glass or broken LCD screen myself?

While it’s possible to repair the cracked glass or broken LCD screen yourself using DIY repair kits, it’s recommended to seek professional help. DIY repairs can be risky and may void your warranty or cause further damage if not done correctly.

5. Will my phone’s warranty cover screen damage?

Screen damage is usually considered accidental damage and is not covered under the standard warranty. However, if you have purchased an extended warranty or insurance plan that includes accidental damage, it may cover the repair costs.

6. How can I prevent my phone screen from getting damaged?

Use a high-quality screen protector and a durable phone case to reduce the risk of screen damage. Avoid exposing your phone to excessive pressure, impacts, or water.


Understanding the difference between cracked glass and a broken LCD screen is crucial for determining the appropriate repair solution and cost. While cracked glass affects only the outer layer and is relatively straightforward to fix, a broken LCD screen involves more complex repairs and higher costs. By recognising the symptoms and causes of each type of damage, you can make informed decisions about repairing and maintaining your mobile phone.
