Original vs OEM vs Aftermarket iPhone Screens

The three grades, plainly

Original is a genuine Apple display, usually pulled from another iPhone, occasionally a service part. OEM-grade (also sold as “soft OLED” or “hard OLED”) is a new OLED panel made by a third-party factory to Apple’s specification. Aftermarket (often “incell”) is a new LCD-type panel engineered to fit an OLED iPhone. All three fit the same frame, connect to the same connector, and support touch, Face ID and the earpiece. The differences are in the picture, the thickness, and the price.

What you can see

• Blacks and contrast. Original and OEM-grade OLEDs switch pixels off for true black. Aftermarket LCD panels have a backlight, so black is dark grey and the screen glows slightly at the edges in a dark room.
• Brightness outdoors. Original panels are brightest. Good OEM-grade panels are close. Aftermarket LCDs are noticeably dimmer in Lahore sun.
• Colour. Original and OEM-grade are close to factory. Aftermarket panels lean cool or slightly washed out, and True Tone is often approximate.
• Thickness. Aftermarket LCDs are thicker, so the screen sits a fraction of a millimetre proud of the frame on some models, and the glass feels different.
• ProMotion. Only original panels deliver a true 120 Hz on Pro models. OEM-grade panels are typically 60 Hz on those models.

What you cannot see

Battery use. An LCD backlight draws more power than an OLED at the same brightness, so aftermarket panels shave some screen time. Durability. Original glass is Ceramic Shield; replacements use ordinary toughened glass and crack more easily, so a protector matters more. iOS notices. On the iPhone 11 and later, any panel not paired through Apple, including a genuine one from another phone, shows “Unknown Part” in Settings. On the iPhone 16 and later, genuine panels can be paired through Repair Assistant, which removes the notice.

Which grade for which phone

iPhone 13 and later, keeping the phone: OEM-grade is the sweet spot; original if you have a Pro and care about 120 Hz. Older iPhone you plan to sell or hand down: aftermarket is fine and honest to the buyer if you say so. Photographers and anyone who edits on the phone: original. Budget is the only constraint: aftermarket gets the phone working properly for the least money, and every grade carries our warranty of up to 6 months. See starting prices on the screen replacement page.

How to tell what you were sold

Turn the brightness to maximum in a dark room and show a black image: an OLED is invisible, an LCD glows. Check Settings → General → About for a “Parts and Service History” entry. And ask for the grade on the receipt; a shop that will not write it down has told you something.
