In recent years, one of the hottest topics in the mobile phone industry is the foldable mobile phone. The foldable mobile phone integrating tablet computer and mobile phone has sounded the horn of new technology.
Mobile phone manufacturers' strategic layout flexible screen
The original idea of opening a tablet and closing a smart device with a mobile phone is no longer a fantasy, but a real product. Samsung and Huawei have launched their own foldable mobile phones. Apple, Xiaomi and other mobile phone enterprises followed closely, carrying out strategic layout and actively promoting the landing of their own flexible screen mobile phones.
The screen of foldable mobile phone adopts flexible OLED screen. The so-called flexible screen refers to the screen that can be bent and folded freely. As a brand-new field, flexible screen faces many problems in the process of processing, which puts forward higher requirements for processing technology. Compared with the traditional processing of brittle materials, OLED displays must be processed with the highest precision in the manufacturing process due to its complex layered mechanism to ensure quality and yield.
Laser is the absolute king of high-precision processing. The processing of flexible screen cannot be separated from the laser cutting process. Cutting flexible screen by traditional mechanical processing is prone to edge collapse, crack and other problems. In contrast, the laser cutting process adopts a non-contact processing method, which will not produce any mechanical stress and has no impact on the mechanical properties of the material itself. After drawing on the computer, the laser cutting machine can realize the special-shaped cutting of the flexible OLED panel according to the design drawings. It has the advantages of automatic cutting, small edge collapse, high precision, diversified cutting, no deformation, fine processing and high processing efficiency.
