The iPhone 14 Plus features a 6.7-inch OLED display that sets a high standard for visual quality and touch performance. For professional repair shops, the choice between OEM (Original Equipment Manufacturer) screens and aftermarket OLED modules is not just about cost—it directly impacts repair efficiency, device longevity, and customer satisfaction.
Kelai (brand: JK), a leading manufacturer of smartphone LCD and OLED modules in China, leverages advanced R&D, precise manufacturing, and global market insight to provide aftermarket screens that deliver near-OEM performance, wide compatibility, and cost-effective solutions. This guide explores the decision-making process for repair professionals, focusing on technical performance, mechanical integration, durability, operational strategy, and advanced repair considerations.
Repair quality depends on more than simply replacing a broken screen. The display is the most visible and interactive component of a smartphone:
Incorrect or low-quality replacements affect brightness, color accuracy, and touch responsiveness.
Poorly integrated screens may lead to early wear, connector failures, or touch panel malfunction.
Operational costs and customer perception are heavily influenced by screen performance and reliability.
Selecting the right screen—whether OEM or aftermarket—has long-term operational and financial implications for repair shops.
Repair professionals must evaluate visual performance metrics to ensure replacement screens meet user expectations.
