Service pack and OEM pull screens keep the phone's original OLED display behavior. Aftermarket OLED costs less with small differences, and aftermarket LCD costs least but is thicker, has weaker blacks and often does not support the under-display fingerprint sensor. Quote at least two tiers and check each listing on the Parts4Cells screens catalog for exact details.
What is the difference between the four screen types?
| Type | What it is | Customer notices | Typical use |
|---|---|---|---|
| Service pack | New screen in Samsung service packaging, often with frame | Looks and works like the original | Premium and flagship repairs |
| OEM pull | Original screen removed from another device and tested | Original display; cosmetic grade varies | Original quality at a lower price |
| Aftermarket OLED | Third-party OLED panel | Slight differences in color, brightness or thickness | Mid-price repairs |
| Aftermarket LCD / incell | LCD-based replacement for an OLED phone | Greyer blacks, thicker, fingerprint sensor often unsupported | Lowest-cost repairs |
Why does screen type affect the fingerprint sensor?
Galaxy S and many A phones read fingerprints through the OLED display. LCD-based replacements put a backlight layer where the sensor needs to see through, so under-display fingerprint unlock often stops working. If the customer relies on fingerprint unlock, quote an OLED option.
How do you pick the right screen for a job?
- Ask what matters most to the customer: price, looks or keeping the phone like new.
- Offer an original-quality option (service pack or OEM pull) and a lower-cost option (aftermarket OLED or aftermarket LCD).
- Write the chosen type on the repair ticket so warranty questions are simple later.
How do you check a screen before installing it?
Connect the new screen to the board before gluing anything. Check touch in every corner, look for dead pixels and tint on white and grey backgrounds, and test brightness from minimum to maximum. A screen that fails the test goes back in its original packaging, without adhesive residue. Most suppliers' return policies require parts to be returned unused.
Frequently asked questions
Is an OEM pull screen new?
No. It is an original screen taken from another device and tested. Display behavior matches the original, and cosmetic condition depends on the grade.
Why is an aftermarket LCD cheaper than an aftermarket OLED?
LCD panels cost less to make. The trade-offs are a thicker assembly, weaker blacks, higher power use and often no under-display fingerprint support.
