What Does "CC" Mean?
🔍 What Does "CC" Mean?
-
CC stands for "Curved Coverage" or "Curvature Coefficient", depending on the manufacturer.
-
It’s an informal industry term often used to indicate the degree of edge curvature that a tempered glass screen protector supports.
📐 What Does "300CC" Specifically Mean?
-
300CC implies a moderate level of curvature, more curved than 100CC or 120CC but not as deep as 500CC.
-
It’s often used on phones with 2.5D or partial 3D curved screens, like certain Samsung Galaxy or Huawei models.
-
The higher the CC number, the more aggressively curved the protector is around the edges.
🧪 Comparison Example:
| Curvature Code | Typical Edge Design | Use Case |
|---|---|---|
| 100CC | Flat or very slightly curved | Flat-screen phones or budget models |
| 120CC | Light 2.5D edge | Basic edge protection |
| 300CC | Moderate curve | Curved screens (e.g., Galaxy S series) |
| 500CC | Deep 3D curve | Full edge-to-edge coverage (premium look) |
🛡️ Summary
The "300CC" in a screen protector refers to its curvature level—offering a good balance between edge protection and screen responsiveness. It’s ideal for phones with moderately curved screens and often provides better edge adhesion than flat protectors.
If you're choosing a screen protector for a curved-display smartphone, knowing the CC rating helps you pick the right fit.
