Since the launch of Nokia N9 in 2011, a word about mobile phone screens has gradually become known to people, which is "2.5D glass". The biggest difference between 2.5D glass and ordinary glass is that although the front of this kind of glass is flat, the edge part will be concave downward into an arc.
In 2014, after Apple iPhone 6 and Samsung Note 4 followed suit, domestic manufacturers began to use 2.5D glass in their flagship products. It is also 2.5D glass, but the level in the industry is uneven. The effects displayed by Xiaomi Note, nubia Z9, etc. are also very different. Because when 2.5D glass is matched with other materials, how to achieve a smooth transition becomes the biggest test. It can be said that how to make good use of 2.5D glass has become a challenge to the industrial design and quality control capabilities of mobile phone manufacturers, and has also become a touchstone for questioning the attitude of mobile phone manufacturers towards their products.
2.5D Glass Eight Immortals Crossing the Sea
When domestic mobile phone manufacturers use the design technology of 2.5D glass, they will always encounter problems of one kind or another due to lack of experience and insufficient skills.
Take Xiaomi Note as an example. Although the front panel uses a 2.5D glass design, due to the insufficient curvature of the 2.5D glass, the visual effect is actually similar to that of an ordinary glass panel. In addition, the magnesium-aluminum alloy middle frame is CNC carved and remains The next sharp edge is bright, and the smooth transition that 2.5D glass should have brought to the hand no longer exists, but instead it fragments the hand feel. Another example is that Nubia Z9 uses optical refraction to cover the black edges of the screen. It uses 2.5D glass with a thickness of 1.7mm. The curvature is exaggerated. Distortion and ribbons caused by optical refraction will appear on both sides of the screen, which will form when looking at the screen from the side. Creates a prism effect, causing image distortion.
Who is the master of industrial design?
All domestic mobile phone manufacturers are keen to use 2.5D glass for their flagship phones, but most mobile phones only use 2.5D glass on the front. If the 2.5D glass on the front reflects the brand’s yearning for beauty, then the use of 2.5D curved glass on both the front and back highlights the brand’s interpretation of beauty.
