What is the purpose of the black border on glass film? What are its benefits?
①Protects the LCD screen right up to the edges
The black bordered glass screen protector protects the edges of the display, preventing damage from drops and impacts, giving you peace of mind.
②Suppression of dust and bacteria on the edges
The black border helps the edges of the film adhere more tightly, preventing dust from accumulating on the edges and preventing the growth of bacteria. This also helps keep your iPhone display cleaner for longer, making it more hygienic.
3. Eliminate air bubbles in gaps
Glass film with a black border has the advantage of being less likely to produce bubbles in the gaps. In particular, the iPhone 15 series, released this year (September 2023), has a rounded edge design, which means that bubbles are more likely to form when the glass film is applied. If you want to completely eliminate bubbles, we recommend a glass film with a black border.

The sliding roller guide frame perfectly fits the iPhone 17, eliminating the need for complicated positioning adjustments. Even first-time users can apply it accurately in one go.
④Reduction of light reflection
By applying a tempered film with a black border, the contrast can be enhanced by the black border, making the entire screen appear clearer. It also reduces the display's reflection, reducing the appearance of discomfort.
⑤Improved sense of unity, comfort and grip
When using full-screen display, the edges of the screen may be cut off. In this case, the black border accentuates the edges of the screen, reducing the sense of incongruity. In addition, the 3D rounded edge processing allows the glass film to fit snugly around the smartphone, eliminating the sense of incongruity of the edges when held in the hand.
*What is 3D? About 3D round edge processing 3D glass films are usually glass films with black borders. The tempered glass has 3D rounded edges, which improves the sharpness of the edges, making it smoother to the touch and better dispersing impacts.
What are the disadvantages of a black border?
① Screen obstruction due to misalignment
If the sticker is not properly attached, the black border may overlap the screen, reducing visibility.
Note: If you are not good at applying the film, we recommend choosing a glass film with a guide frame or made of a sturdy material.
② Interference with the case
If it has a black border, it may interfere with some cases, so you should check case compatibility, especially if the screen protector is thick.
