Beyond the Screen: Sourcing Essential Phone Display Parts for Repairs

When I started STMAX in 2016, the industry focused entirely on the finished screen assembly. But as the market matured, I realized that the real pros—the refurbishment factories and the master technicians—needed more. They needed the raw phone display parts to perform surgical repairs. They didn't just want to swap a screen; they wanted to rebuild it.

Take the backlight, for example. It’s a sandwich of reflective sheets, diffusers, and prisms. If you use a cheap replacement backlight sheet, the screen looks uneven. We source our backlight materials from top-tier Japanese and Korean suppliers. When we sell you phone display parts like backlight units, we are selling you uniformity and brightness that matches the OEM standard.

Then there is the glass lens. In the refurbishment game, the glass is everything. We sell "Cold Carve" glass that fits the curvature of the phone perfectly. I've seen cheap glass that is slightly flat, causing it to lift off the frame after a week. Our glass phone display parts are precision-molded to exact tolerances. We also ensure the oleophobic coating is applied via electroplating, not just a cheap spray, so it lasts for months, not days.

We also focus on the humble frame adhesive. It’s just a sticker, right? Wrong. It’s the water seal. It’s the dust barrier. We use high-viscosity, water-resistant adhesives for our phone display parts. We want a technician to feel confident that when they seal a phone, it stays sealed.

At STMAX, we understand that a repair is only as good as the weakest component. That is why we apply the same rigorous QC to a $0.50 bracket as we do to a $50 screen. Whether you are buying the whole assembly or the individual phone display parts, you are getting the STMAX guarantee of quality.
