With the continuous development of 3C products such as smartphones, smartwatches, tablet PCs, etc., consumers are demanding more and more on the appearance design and tactile experience of the products. 3D curved glass has gradually become the mainstream choice for touch screen glass covers due to its unique design and excellent physical properties.
3D curved glass, i.e. 3 Dimensional Glass, is a kind of screen glass with three-dimensional curvature, which adopts curved design both in the middle and at the edges.
Functional advantages:
Touch Feeling: Curved edge design brings excellent touch feeling.
Aesthetics: make the product more beautiful, increase the differentiation of product design and attract consumers.
Production process and technical challenges of 3D curved glass:
Production process: The production process of 3D curved glass is basically the same as that of 2D and 2.5D products, but the biggest difference lies in the addition of new hot bending molding equipment. 3D glass needs to use the hot bending process, while polishing and silk-screen printing processes need to be carried out on the bended glass, which has resulted in high construction difficulty, low yield rate and relatively high cost.
Technical challenges: Due to the complexity of the production process of 3D curved glass, the technical difficulty is high, thus restricting its large-scale application. However, as various processing manufacturers increase their R&D efforts, the yield of hot pressing continues to improve, and the cost is also reduced, gradually promoting the wide application of 3D curved glass in the glass cover of touch screen.
In summary, the glass cover of the touch screen can use 3D curved glass, and has many functional advantages. With the continuous improvement of the production process and the gradual overcoming of technical challenges, the application of 3D curved glass in touch screen glass cover will become more and more widespread.
