LCD Screen Damage on Phones

What Causes LCD Screen Damage on Phones?

One common cause is physical impacts, such as accidental drops or forceful impacts, which can lead to cracks, fractures, or other forms of damage. Exposure to extreme temperatures, both high and low, can also adversely affect the LCD screen, causing it to malfunction or develop issues. 

Additionally, manufacturing defects in the screen or internal components can contribute to screen damage. Water or liquid exposure is another significant cause, as it can seep into the device and harm the delicate LCD components. 

The Most Common Causes of LCD Screen Damage on Phones

Understanding these causes is crucial for preventing and addressing LCD screen damage on phones.

1. Physical Damage

Physical damage is the most common cause of LCD screen damage on phones. Accidental drops, impacts, or mishandling of the device can result in cracks, fractures, or other harm to the delicate liquid crystal display (LCD) screen. 

2. Water Damage

Water damage poses a significant threat to phone LCD screens. Exposure to moisture, be it from spills, rain, or submersion in liquids, can infiltrate the internal components of the device, causing irreparable harm to the LCD screen. The sensitive nature of the screen makes it susceptible to malfunctioning and distortions when it comes in contact with the water. 

3. Extreme Temperatures

Extreme high and low temperatures can cause LCD screen damage on phones. Prolonged exposure to heat or cold can affect the LCD’s functionality and lead to screen discoloration, pixel damage, or even complete failure. 

4. Not Using a Screen Protector

The absence of a screen protector leaves the phone’s LCD vulnerable to scratches, smudges, and minor impacts. Screen protectors act as a shield, providing an additional defense against everyday wear and tear. Without this protective layer, the LCD is more susceptible to damage from pocket objects, accidental scrapes, or surface interactions.

5. Manufacturing Defects

Some LCD screen damage is attributed to manufacturing defects. While modern manufacturing processes aim for precision, occasional defects may slip through, leading to malfunctions or abnormalities in the screen. 

These defects can manifest as dead pixels, color irregularities, or other issues that compromise the overall performance and longevity of the LCD.

6. Poor Maintenance

Inadequate maintenance practices can accelerate LCD screen types of damage on phones. Failing to keep the phone in a protective case, placing it in pockets with keys or other sharp objects, or neglecting regular cleaning can result in scratches, dents, or abrasions on the screen. 

Over time, these seemingly minor issues can accumulate, ruining the overall quality and appearance of the LCD.

Preventative Measures of LCD

  • Use a protective case to guard against physical damage.
  • Use a screen protector to prevent scratches and minor impacts.
  • Avoid exposing the phone to water or moisture-prone environments.
  • Keep the phone away from extreme temperatures, both hot and cold.
  • Practice good maintenance by cleaning the phone regularly and storing it safely.
  • Avoid placing the phone in pockets with keys or other sharp objects.
  • Consider environmental factors, such as sunlight exposure, to prevent screen damage.
  • Stay mindful of potential manufacturing defects and address them promptly when identified.

What are the types of LCD damage?

Common types of phone screen damages include cracks or shattered screens due to physical impact, dead pixels causing black dots or distorted colors, backlight issues leading to uneven brightness or flickering, screen burn-in from prolonged display of static images, and water damage causing internal component irregularities. Identifying the type of damage is essential for determining the appropriate course of action, whether repair or replacement.

What causes the phone LCD to break?

Phone LCDs commonly break due to physical damage, often resulting from accidental drops, impacts, or pressure on the screen. Additionally, exposure to extreme temperatures or manufacturing defects can contribute to LCD breakage. The vulnerability of LCDs to external forces makes them prone to cracks and fractures.

Can the LCD screen be repaired?

Yes, a damaged LCD screen can often be repaired. The extent of the repair depends on the nature and severity of the damage. Minor issues, such as small cracks, may be fixable through local phone repair services. Technicians can replace damaged parts or repair the LCD itself. However, extensive damage may require a full LCD replacement, necessitating assistance from authorized service providers or experienced technicians.

What causes LCD to go black?

The LCD going black can result from various factors, including a malfunctioning backlight, loose or damaged connections, software issues, physical damage, or a faulty power supply. Troubleshooting may involve inspecting hardware, addressing software glitches, or seeking professional assistance to diagnose and resolve the specific cause.


These are some of the preventative measures to help you avoid LCD Screen damage. Experts advise you to get your screen repaired immediately to avoid inconvenience. Now that you know the causes of LCD Screen damage, practice good maintenance and avoid the practices mentioned above to ensure your phone screen stays in good condition.
