Flat light guide plate with LED as light source
The precision required by the light guide plate mold is in the micron level, which belongs to the category of precision micro-nano processing. The traditional combination of servo motor and screw drive can no longer meet the needs of micro-nano technology in the processing and manufacturing industry, resulting in many new micro-displacement drive components, such as voice coil motors, piezoelectric ceramic drives, and so on. Among them, piezoelectric ceramics have become the first choice for micro-nano applications due to their advantages of high displacement control accuracy, fast response speed, large driving force, low driving power and wide operating frequency. Because processing the microstructure on the light guide plate mold requires a small feed stroke, and the required accuracy and frequency are high, piezoelectric ceramics can be used as the core driving element of the collision machine.
