the causes of poor breakage in the bending area of the LCD display's FPC

 What are the causes of poor breakage in the bending area of the LCD display's FPC, and what are the directions for optimization? 

Answer：The FPC of the LCD screen is fractured. Possible causes include the bending radius being too small, less than the design allowable value. Generally, it should be ≥3 times the FPC thickness. Alternatively, the tensile force during assembly may exceed the FPC's tensile strength (standard FPC is approximately 50-100 N/cm²).
