Application of Laser Technology in Foldable Smartphone Manufacturing

As technology continues to advance, foldable smartphones have introduced a revolutionary user experience with their unique flexibility. What makes these devices so smooth and satisfying to use? The answer lies in the application of laser technology in foldable screen manufacturing.

1. Laser Cutting Technology: The Tool for Precision

The glass used in foldable smartphones must be ultra-thin, flexible, and lightweight while maintaining excellent transparency. Ultrafast laser cutting technology ensures precise cutting of the screen glass with high efficiency. Compared to traditional methods, laser cutting offers finer contour shaping, minimal edge chipping, and superior accuracy, significantly improving product yield and processing efficiency.

2. Laser Welding Technology: Bridging Precision Components

Laser welding is extensively used in manufacturing critical components like the hinges and folding mechanisms of foldable smartphones. This technique guarantees aesthetically pleasing and consistently high-quality welds while enhancing the mechanical properties of materials. Laser welding effectively addresses challenges such as deformation, dissimilar material welding, and high-reflectivity material joining.

3. Laser Drilling Technology: The Expert in Precision Positioning

In AMOLED module manufacturing, laser drilling technology plays a crucial role. Automated flexible OLED laser drilling equipment ensures precise energy control and beam quality, offering reliable solutions for fabricating flexible display components.

4. Laser Repair Technology: Key to Enhanced Display Quality

Laser repair technology demonstrates immense potential in correcting bright spots on OLED and LCD screens. High-precision laser devices can automatically identify and precisely locate screen defects—whether bright spots, dim spots, or partial dark spots—and repair them to improve display quality.

5. Laser Lift-Off Technology: Enhancing Product Performance

During OLED manufacturing, laser lift-off technology is used to detach flexible panel modules. This technique contributes to improved product performance and quality.

6. Laser Inspection Technology: The Quality Guardian

Laser inspection, such as FFM laser testing, ensures that foldable smartphones meet stringent quality and performance standards.

The Role of Water Chillers in Laser Processing on Smartphones

Laser processing generates significant heat, which can lead to output instability, affecting product quality or even damaging laser equipment. A water chiller is essential for maintaining stable temperature control. TEYU water chillers, available in various models, provide reliable cooling solutions for diverse laser equipment. They ensure smooth operation, enhance processing quality, and extend the lifespan of laser systems.

Laser technology is indispensable in foldable smartphone manufacturing. It not only enhances production efficiency and product quality but also drives the advancement of flexible display technology.
