Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 3:
4. A handwriting processing system, comprising:
a pen display comprising a display module, a transducer, a first wireless communication module and a first processing module being electrically connected with the display module, the transducer and the first wireless communication module, the transducer detecting and further generating a transformed handwriting data;
a data processing device comprising a second processing module and a second wireless communication module being electrically connected with the second processing module, the second wireless communication module being wirelessly coupled to the first wireless communication module;
wherein the data processing device obtains the transformed handwriting data by the second wireless communication module; after the data processing device receives the transformed handwriting data, the data processing device generates a compressed screen image and captures a part of handwriting image of the transformed handwriting data to form a captured handwriting data; the data processing device further transmits the compressed screen image and the captured handwriting data which is not compressed to the pen display by the second wireless communication module; the first processing module uncompresses the compressed screen image and overlaps the uncompressed screen image and the captured handwriting data which is not compressed to form a complete screen image; the display module displays the complete screen image.
