In this article, we will introduce the effect of black borders, their advantages and disadvantages, and the difference between them and borderless films. We will also introduce recommended usage methods and actual customer feedback.

What is the black border on glass film for? What are its benefits?
①Protects the LCD screen up to the edges
The black-rimmed glass film protects the edges of the display, preventing damage from drops and impacts. You can use it with peace of mind.
② Suppression of dust and bacteria on edges
The black border helps the edges of the film to fit tightly, preventing dust from accumulating on the edges and preventing the growth of bacteria. It also keeps your iPhone display clean for longer, which is effective from a hygienic standpoint.
3. Eliminate air bubbles in gaps
Glass films with black edges have the advantage of being less likely to cause air bubbles in the gaps. In particular, the edges of the iPhone 15 series released this year (September 2023) have a rounded edge design, so there is a disadvantage that air bubbles are easily trapped when the glass film is applied. If you want to thoroughly eliminate air bubbles, we recommend a glass film with a black edge.
4. Reduction of light reflection
By applying a tempered film with a black border, the contrast can be enhanced by the effect of the black border, making the entire screen appear clearer. It also reduces the appearance of discomfort by making it harder for the display to reflect light.
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 film is usually a glass film with a black border. The tempered glass has been given a 3D rounded edge treatment, 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 glass 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 the compatibility with your case, especially if the film is thick.
