AI Technical Summary
Existing foldable display devices face challenges in maintaining reliability due to stress and damage during the manufacturing process, particularly in the folding area, leading to defects such as cracks from repeated folding operations.
A foldable display device with a window featuring different surface roughness in folding and non-folding areas, where the folding area has a lower surface roughness to reduce stress and damage during the laser cutting process, and a method involving distinct laser processes for cutting the display module, using a lower energy laser beam in the folding area to minimize defects.
The approach reduces stress and damage in the folding area, minimizing defects and enhancing the reliability of the foldable display device by ensuring smoother surface modifications and reduced crack formation during repeated folding.
