1. A handwriting data processing method, which is applied to a pen display and a data processing device, the pen display being connected with the data processing device in a wireless communication manner, the handwriting data processing method comprise steps of:
the data processing device obtaining a transformed handwriting data from the pen display in the wireless communication manner; the data processing device generating a compressed screen image and capturing a small range of a handwriting image of the transformed handwriting data to form a captured handwriting data; the data processing device further wirelessly transmitting the compressed screen image and the captured handwriting data, which is received and not compressed, to the pen display;
the pen display uncompressing the compressed screen image, the pen display overlapping the uncompressed screen image and the captured handwriting data which is not compressed to form a complete screen image and displaying the complete screen image.
