When a customer drops an iPhone and shatters the outer glass but the LCD/OLED beneath still works, your shop has two paths: replace the full display assembly, or attempt a glass-only repair by separating the panel. The second is higher margin and higher risk. Here is how to decide per job.
The Economics Side by Side
| Factor | Full Assembly Swap | Glass-Only Repair |
|---|---|---|
| Part cost | High (whole assembly) | Low (glass + OCA + frame tape) |
| Bench time | 20-40 min | 60-120 min with lamination equipment |
| Success rate (typical shop) | Near 100% | 70-90% depending on panel type |
| True Tone / brightness retention | May need transfer or pairing | Preserved - original panel stays |
| Risk | Low | Panel cracking during separation; ghost touch after lamination |
Which Panels Tolerate Glass-Only
- Good candidates: iPhone 8 through 11 LCD assemblies, XR/11 panels - forgiving separation, cheap donors for practice.
- Possible with care: 12/13 OLED - thin panels, higher crack-out risk, needs a constant-heat platform.
- Not recommended: ProMotion OLEDs and 14/15 assemblies - separation failure rates erase the margin on most used prices.
Equipment Reality Check
Glass-only only pencils out with a heated platform, a wire or molybdenum saw rig, an autoclave or vacuum OCA laminator, and bubble-removal gear. Shops that try the job with a heat gun and hand lamination ship ghost-touch comebacks that cost more than the saved part money.
Decision Rule for the Counter
Quote glass-only when: device value is mid-range or lower, the panel is confirmed working (touch test all corners), and your shop has the lamination rig. Quote full assembly when the panel has any touch fault, when it is a flagship OLED, or when the customer needs same-day turnaround.

FAQ
Does glass-only keep Face ID working? Yes - the original panel and sensors stay in place, so no pairing issues.
What is the most common glass-only failure? Ghost touch after lamination, usually from trapped debris or an over-heated panel.
Can we offer both and let the customer choose? That is the best counter script: fast/full vs cheaper/slower with a stated risk.
