Designed for repair professionals
A professional-grade Soft OLED panel combined with technology designed to simplify repair setup on compatible iPhone models.
Designed to support repair setup and display a compatible status in iOS, depending on the model and software version.
A flexible panel delivering deep blacks, good brightness, and precise touch response.
A screen selected and tested to limit excessive power consumption, especially in standby.
A Diagnostic Soft OLED screen supplied without a pre-installed sensor flex cable. The technician prepares and installs the proximity sensor using their usual method.
The same Diagnostic Soft OLED screen, with a pre-installed proximity sensor. This preassembled configuration reduces handling, simplifies preparation, and speeds up installation.
The iPhone checks the installed screen’s electronic information and its connection to the device.
The additional D‑Pro circuit is designed to communicate with the iOS diagnostic and repair setup process.
After successful setup, the iPhone may register the repair and display a compatible status in its history.
A conventional screen may work correctly while being identified as an “Unknown Part.” Depending on the model and iOS version, D‑Pro may allow a status such as “Used” to appear after the applicable procedure.
This technology may eliminate the complex transfer of the old screen’s identification circuit when the model supports it. It does not make the screen a genuine Apple part and does not mean that the repair is certified by Apple.
The exact procedure varies depending on the iPhone model and iOS version. When Repair Assistant is supported:
A tool, activation, or additional steps may be required for some models or software versions. The technician must always follow the procedure that matches the exact product being installed.
D‑Pro screens are selected and undergo comparative testing to limit excessive battery drain when the device sees little use.
Each pixel produces its own light. However, power consumption varies with brightness, displayed colors, and actual usage.
Diagnostic technology primarily supports part recognition and setup. Energy efficiency depends on the overall screen design; the Diagnostic function alone does not guarantee longer battery life.
Actual battery life varies depending on the iPhone model, battery health, brightness, iOS version, active apps, network, and usage conditions.
Diagnostic technology is tested with the iOS versions available when the product is introduced. Its operation depends in part on the operating system, diagnostic tools, and Apple’s recognition mechanisms.
A future iOS update or a change to these systems could:
The screen’s hardware quality and warranty remain unchanged. However, the result obtained after the diagnostic procedure cannot be guaranteed to remain permanently available in future iOS versions.
For eligible manufacturing defects. Eligible internal Soft OLED panel breakage is also covered after inspection, in accordance with the general terms.
An eligible screen hardware defect, as well as eligible internal OLED panel breakage, after inspection.
The reappearance of an authenticity, verification, or history message following an iOS update or a change to Apple’s systems is not a covered hardware defect.
External damage, impacts, cracks, liquid damage, excessive pressure, damaged flex cables, improper installation, or improper use remain excluded.
D‑Pro and D‑Pro+ screens are compatible replacement parts. They are not genuine Apple parts and are neither certified nor approved by Apple.
Subject to applicable statutory warranties, the limitation related to updates concerns software recognition only, not an eligible screen hardware defect.
To the extent permitted by law, the commercial warranty is limited to providing a remedy for the part confirmed to be defective. Labor costs, data loss, lost revenue, and other consequential damages are not covered.
Compatibility with the diagnostic procedure is verified using the iOS versions available at the time of sale. A future update may change part recognition without necessarily affecting its hardware operation.
