Why is there a black border around the screen of iphone6plus?
Many consumers have a misunderstanding here, that is, they think that the mobile phone screen with white body has black edges, while the mobile phone screen with black body has no black edges, but in fact this phenomenon exists in any color of the body. The white fuselage looks very obvious, because the frame of the fuselage is white, in contrast to the black edge of the screen. However, because the frame and black edge of the black fuselage are black, a consistent vision is formed in color, which will make people mistakenly think that the black edge has disappeared.
The black border is the BM area.
There is a famous saying that "existence is reasonable". So this nasty black border doesn't exist for no reason. Its existence must have its function. This black border is considered from the design level, and its scientific name is BM area.
The primary function of BM area is to prevent the screen from leaking light. If there is no BM area on a screen, you will see obvious halo at the edge of the screen. Because there are some errors in the assembly of the screen of each mobile phone, it is impossible to achieve absolute alignment. If the screen frame is aligned with the visible edge of BM area, color glare will appear at the edge of the frame, and the mobile phone with white frame may reflect the screen light, and bright edges will appear around the screen. At present, some mobile phone screens have obvious light leakage, which is caused by the large assembly error of the screen and the inability to effectively block the BM area.
Another reason is the black edge caused by the distance between the internal and external screens of the mobile phone. Many product screens not only have black borders, but also have narrow black borders inside. This is because the mobile phone screen is generally divided into two layers, the innermost layer is the display layer and the outermost layer is the protective glass touch layer. There is still a certain distance between the inner display screen and the protective glass. With the distance, dark shadows will naturally appear, which is also normal.
