The so-called flexible screen refers to the screen that can be bent and folded freely. As a new field, flexible screen is faced with many problems in the process of processing, which puts forward higher requirements for processing technology. Compared with the traditional brittle material processing, OLED display must be processed with the highest precision in the manufacturing process because of its complex layering mechanism to ensure the quality and yield. To meet such high requirements and high precision processing conditions, laser cutting technology is the best choice. The laser can concentrate the light energy in the time interval from picosecond to femtosecond, and focus the light to the ultra fine space area. The extremely high peak power and extremely short laser pulse ensure that the processing process will not affect the materials outside the involved space range.
Laser cutting technology adopts non-contact processing method, which will 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 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. At the same time, there is no need to wash, grinding, polishing and other secondary processing, reducing the manufacturing cost. However, the traditional machining method is easy to cause edge collapse, cracks and other problems.
