Application of picosecond laser cutting machine on flexible screen

The so-called flexible screen refers to a screen that can be bent and folded freely. As a brand-new field, flexible screens are faced with 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.

       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 drawings. It has the advantages of automatic cutting, small cutting edge collapse, high precision, diversified cutting, no deformation of cutting, fine processing, and high processing efficiency. . 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.
