iPad cracked glass vs. cracked LCD

Glass vs. LCD: what's actually underneath

An iPad screen is a sandwich. On top is the glass digitizer (the part you touch). Underneath is the LCD or OLED panel (the part that lights up the image). They're two separate components — and on most iPads they can fail independently.

Signs it's JUST the glass (cheaper repair)

If all of these are true, you most likely have a glass-only crack.

• You can see cracks or chips on the surface, but the picture underneath is perfect.
• Touch still works everywhere on the screen.
• No black spots, no rainbow lines, no bleeding ink-like patches.
• No dead zones where touch is unresponsive.

Signs the LCD is also damaged (pricier repair)

If any of these show up, the LCD underneath is also cracked.

• Black blotches, ink-like bleeding patches, or areas where the backlight shows but no image.
• Rainbow / oil-slick lines spreading from the crack.
• Vertical or horizontal lines down the screen.
• Sections of the screen stay black even though the iPad is clearly on.
• Touch is dead in entire zones (not just at the crack).

Why the price difference?

On older iPads (iPad 7th–10th gen, older iPad Mini, older iPad Pro), the glass and LCD are separate parts. We can replace just the glass for a lot less.

On newer iPad Pro models with laminated displays, the glass and LCD are bonded into one assembly — even a glass-only crack means swapping the whole thing. That's why iPad Pro repairs are higher than a standard iPad.

Should you fix a hairline crack if the screen still works?

Usually yes. Reasons:

• Cracks spread — every drop or temperature change pushes the crack further across the glass.
• Glass chips cut fingers. Especially bad for kids' iPads.
• Moisture and grit get under the glass and damage the LCD. A $129 glass repair this week is cheaper than a $300+ LCD repair next month.
