Green laser beam high-precision cutting flexible screen
Aug 19 , 2021In recent years, one of the hottest topics in the mobile phone industry has been foldable mobile phones. Foldable mobile phones that integrate tablet computers and mobile phones have sounded the clarion call for new technologies. The smart device that was originally supposed to be a tablet when opened, and a mobile phone when closed, is now no longer a fantasy, but a truly tangible product. Samsung and Huawei have launched their own foldable phones. Mobile phone companies such as Apple and Xiaomi closely behind and made strategic arrangements to actively promote the implementation of their own flexible screen mobile phones.
The screen of the foldable mobile phone uses a flexible OLED screen. The so-called flexible screen refers to a screen that can be bent and folded freely. As a brand-new field, flexible screens face many problems in the processing process, and higher requirements are put forward on the processing technology. Compared with traditional brittle material processing, OLED display screens must be processed with the highest precision in the manufacturing process due to its complex layering mechanism to ensure quality and yield.

Laser is the absolute king of high-precision processing. The processing of flexible screens is inseparable from the laser cutting process. Cutting flexible screens by traditional mechanical processing methods is prone to problems such as chipping and cracking. In contrast, the laser cutting process uses a non-contact processing method, which does not produce any mechanical stress and has no effect 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 drawing. It has the advantages of automatic cutting, small cutting edge collapse, high precision, diversified cutting, no deformation of cutting, fine processing, high processing efficiency, etc. .
RFH Laser has launched a high-precision laser cutting machine for the cutting of flexible OLED screen panels. It uses imported lasers and optical devices with good spot quality; it improves the curling phenomenon that occurs during cutting for the touch screen industry materials; strengthened welding bed, casting The aluminum gantry structure and cast iron chassis, together with the high-precision marble platform, ensure the stability of the machine tool during processing; the independently developed laser cutting software integrates excellent motion control performance and powerful graphics processing functions. It is suitable for the mass production of flexible OLED screens of folding mobile phones.
In addition to being suitable for flexible OLED screen processing, high-precision CO2 laser cutting machines are also widely used in high-precision cutting of other non-metallic film materials of various electronic products, such as GDF film, polarizer, touch screen PET, OCA, electronic paper , PC, foam double-sided tape, etc.
The bendability of flexible OLED screens will undoubtedly make mobile phones, tablets and other commonly used 3C electronic devices, revolutionary changes, especially for mobile phones with one hand, the emergence of bendable screens will greatly increase the screen-to-body ratio once again The improvement of the mobile phone can also greatly reduce the space occupied by the mobile phone. Like a wallet, it can be folded when not in use, reducing the space occupied, and unfolded when in use, so as to obtain the visual experience of a large screen.
