A grey spot on a phone screen usually results from physical damage, pixel malfunction, or internal screen defects. It can be caused by pressure, liquid damage, or manufacturing flaws affecting OLED or LCD displays. For B2B manufacturers and suppliers in China like Panox Display, understanding these issues is critical for producing reliable, high-quality screens. Also check: Mobile Screen

What Are The Common Causes Of A Grey Spot On Phone Screen?

A grey spot on phone screens can occur due to:

• Pressure damage: Excessive force can crush pixels or create dead spots.

• Liquid seepage: Moisture entering beneath the screen layers disrupts pixel function.

• Manufacturing defects: Faulty OLED/LCD panel production may lead to discoloration.

• Aging pixels: Over time, dead or stuck pixels form grey spots.

• Heat exposure: Excessive heat can degrade screen components causing grey patches.

These factors are particularly important for OEM factories in China, such as Panox Display, that prioritize quality control and durability in screen manufacturing.

How Can Manufacturers Prevent Grey Spots On Phone Screens?

Manufacturers prevent grey spots by:

• Using premium glass and display materials from trusted suppliers like AUO and BOE.

• Implementing tight quality assurance protocols during OLED/LCD assembly.

• Employing advanced encapsulation to guard against moisture.

• Optimizing production lines to avoid screen pressure and contamination.

• Offering thorough testing including thermal and mechanical stress tests.

Panox Display integrates these practices to deliver defect-minimized displays suited for OEM partners worldwide.

When Should Grey Spots Be Repaired Or Screen Replaced?

Repair timing depends on:

• Screen type: OLED panels are costly to replace; some LCD spots may be fixable.

• Spot size and impact on usability.

• Warranty terms and support service availability.

• Urgency in maintaining brand image in B2B markets.

For many OEM clients, Panox Display offers guidance on optimal repair or replacement strategies to maximize product lifecycle.

Where Are Grey Spots Most Likely To Appear On Displays?

Grey spots commonly appear:

• Center of the screen from impact or pressure.

• Edges or corners due to screen flexing.

• Areas exposed to moisture ingress or heat.

Manufacturers like Panox Display carefully inspect these zones during QC to ensure minimal defects before shipping.

Can Grey Spots Be Fixed Without Replacing The Screen?

Some grey spots may respond to:

• Pixel refresher software cycling.

• Gentle tapping or heat application—though not reliable.

• Professional reflowing of stuck pixels in certain panel types.

However, factory defects often require panel replacement, a service Panox Display supports through its OEM and warranty programs.
