The mobile repair industry has taken significant steps over the past several months. The middle of the road aftermarket screen has evolved. Mediocrity has given rise to a better, more reliable, extreme-copy screen that will give users an experience much closer to their original counterpart. This is a huge win for independent repair stores who are looking to build a lasting brand.

The release of these new extreme-copy screens has created a much needed boost in quality standards for our industry starting with the Chinese factories who assemble them, and it’s our job as an industry, vendors and shop owners alike, to drive the change forward.

Common LCD Structure on High Copy Aftermarket

The Sourcely team has been working hard to source the right raw materials and the right engineering team dedicated to building displays that are as close to the original as possible, but affordable enough to maintain viability in the marketplace.

First let’s take a look at how the existing extreme-copy screens compare to OEM and the key differences:

Most Significant Changes:

  • Backlight (ESR)

The biggest and most important improvement is in the backlight. Unlike regular aftermarket screens, high copies use a 3M ESR (Enhanced Specular Reflector) Film providing brighter colors, better viewing angles, and a more efficient display.

On the downside, the new high-copies have overpowered the backlight to get the brightness (Nits) up. This effectively sacrifices the refresh rate that is part of the Graphics processor by pulling more power to the backlight. The result is an image being redrawn at a slower rate which causes a delay commonly referred to as “jelly effect” as seen below:

  • Proprietary Formula Glass

When it comes to the front glass, although some high copy manufacturers claim to use “Corning” glass, we have found that not to be true when we did a teardown of the screen. Instead, they use a normal copy glass but increased the tempering time. We also found that the high copy displays are using a special liquid nano tempered glass on top of their regular copy glass. The nano coating Strengthens the glass on a molecular level which is allowing it to pass the 2m flaa/ball impact test and the glass flexion test.   

  • OCA Tape

Another significant change is with the OCA adhesive. While OEM vendors use a 150-175μm OCA, high copy screens use a 200μm. The 175μm tape gives the display slightly better light control and touch since touch panels are closer. However, the thicker the OCA is, the higher the chances of bubbles and rainbows on the screen in the future.

Although these changes are significant, we still need to keep in mind that a copy is a copy – even if it’s a high one. This means that the LCD, brightness, touch, and other important components still don’t have the original quality, but are getting much closer.


Why are we talking about this? Because all these amazing advances have made us decide to raise our own bar. We understand that product quality is a never-ending work in progress and we decided to contribute as well. We recently hired one of the best people in the industry to take on our Quality control and vendor relationships and bring us one rung further up the ladder. We will continue our R&D working closely with factory engineers and China market analysts to ensure we always provide top products to our clients.

We are proud to announce that Sourcely is introducing a new generation of extreme-copy aftermarket screens.

No smoke and mirrors and no over-hyped marketing, we want to be completely transparent and inform our clients of exactly what is going into their build. We will always share the details of our display assembly, how new designs differ from what’s currently on the market, and what remains the same during design changes.
