Glass as a touchstone for questioning  mobile phones?

          Since the launch of the Nokia N9 in 2011, a word about the mobile phone screen has gradually become known to people, and this is "2.5D glass". The biggest difference between 2.5D glass and ordinary glass is that although the front of the glass is flat, it will be recessed into an arc at the edge.

In 2014, after Apple iPhone 6 and Samsung Note 4 followed up,   manufacturers used 2.5D glass in their flagship products. The same is 2.5D glass, but the level in the industry is uneven, and the effects exhibited by Xiaomi Note and nubia Z9 are also very different. Because 2.5D glass is matched with other materials, how to achieve a smooth transition has become the biggest test. It can be said that how to make good use of 2.5D glass has become a challenge for the industrial design and quality control capabilities of mobile phone manufacturers, and it has also become a touchstone to torture the product attitude of mobile phone manufacturers.

2.5D glass eight immortals cross the sea

When   mobile phone manufacturers use the design technology of 2.5D glass, due to lack of experience and insufficient skills, they will always encounter one or other problems.

Taking Xiaomi Note as an example, although the front panel adopts the design of 2.5D glass, due to the insufficient curvature of 2.5D glass, the visual effect is actually the same as that of the ordinary glass panel, plus the magnesium alloy aluminum frame for CNC carving The next sharp ridgeline bright surface, 2.5D glass should have brought a smooth transition on the hand, and there is no longer a hand. Instead, the hand feel is split. Another example is nubia Z9. In order to cover the black edge of the screen with optical refraction, 2.5D glass with a thickness of 1.7mm is selected. The bending arc is exaggerated. The distortion and color band phenomenon caused by optical refraction will appear on both sides of the screen. The effect of a prism caused distortion of the image.

Who is awesome in industrial design

Various   mobile phone manufacturers are keen to use 2.5D glass for their flagships, but most mobile phones only use 2.5D glass on the front. If the front 2.5D glass reflects a brand's longing for beauty, then the use of 2.5D curved glass on the front and back simultaneously shows the brand's interpretation of beauty.
