Looking back at history, in 2019, Huawei released the first generation of folding screen Mate X, opening a new era of 5G folding screen mobile phones; in 2020, Huawei released the second generation of folding screen Mate Xs, realizing the evolution of folding screen phones from hardware to ecology. Today, Huawei has released a new generation of folding flagship Mate X2, the trinity of top hardware, innovative interaction, and application ecology, defining the industry standard for folding flagships. In fact, the head phone manufacturers have basically entered the game. In addition to Huawei and Samsung, Apple, Xiaomi, OPPO, and vivo have some new trends. This year, at least seven or eight new foldable screens will be released, and the market will be more lively.
To meet such high-requirement and high-precision processing conditions, laser cutting technology is the best choice now. The laser can concentrate the light energy in the time interval of picoseconds to femtoseconds, and focus the light into the ultra-fine space area. The extremely high peak power and extremely short laser pulse ensure that the processing process will not affect the space involved. The impact of external materials. 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. . At the same time, there is no need for secondary processing such as washing, grinding, polishing, etc., which reduces manufacturing costs. However, the use of traditional mechanical processing methods to cut the flexible screen is prone to problems such as chipping and cracking.
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 to reduce the space occupied, and it can be unfolded when in use to obtain the visual experience of a large screen.
