Best laser processing method for OLED screens

One of the hottest topics in the mobile industry is the foldable phone. This foldable phone, which is composed of a tablet and a mobile phone, has sounded the clarion call for new technology.

Originally, it was thought that the smart device, which was a tablet when opened and a mobile phone when closed, is no longer a groundless rumor, but has become a real product. Royole Technology, Samsung, Huawei and others have launched their own foldable phones. Apple, Xiaomi and other mobile phone companies have also followed closely, making strategic arrangements and actively promoting the implementation of foldable phones.

Foldable mobile phone screens use flexible OLED screens, that is, the screens can be bent and folded freely. As a brand-new field, flexible screens have encountered many problems during the processing process, and higher requirements have been put forward for the processing technology. Because the structure of OLED display screens is complex, compared with traditional brittle material processing, to ensure the quality and quality of the products, the maximum precision must be achieved.

Compared with the traditional four-corner right-angle cutting, the shape of mobile phone screens has changed greatly, including water drop screens, bangs screens, full screens and the latest folding screens. For this kind of cutting method, if the traditional additive cutting method is used, problems such as edge collapse, cracks, and poor precision are prone to occur, which will lead to a significant increase in the product defect rate. On this basis, the laser cutting process adopts a contactless processing method, which is suitable for processing thin glass and ultra-thin glass, has the ability to cut special shapes, has the advantages of small edge collapse, high precision, and good cutting edge quality, and significantly improves processing efficiency and processing efficiency. The best laser processing method for OLED screens is achieved.

For cutting flexible OLED screen panels, LASEY Laser has launched an OLED picosecond laser cutting machine. The cutting machine uses imported lasers and optical components, with good spot quality, fast processing speed and high efficiency, high beam quality, stable performance, high beam quality, minimal heat-affected zone and distortion, nonlinear processing, and a wide variety of processable materials. It can be used with various metal and non-metal materials such as stainless steel, aluminum, titanium alloy, sapphire, ceramics, glass, etc., such as PCB cutting, drilling, flat panel display tempered glass, thin film cutting, wafer lithography, and various other industrial manufacturing, solar broadcasting, biological instruments, scientific research, etc.

The emergence of flexible OLED screens undoubtedly shows that domestic technology is developing rapidly and various technologies are constantly iterating and innovating. I believe that in the near future, foldable mobile phones will truly enter the lives of ordinary people.
