Abstract: The present disclosure is related to a system and a system for displaying handwriting synchronously, and a handwriting device thereto. The handwriting device adopts a bistable display panel and includes a sensor circuitry that is used to record the handwriting contents over the panel. The sensor circuitry through the handwriting renders handwriting positions and pressure values. These sensed data is transmitted to a computer device instantly when the data of positions and pressure values are generated by the handwriting device. In the computer device, the handwriting can be synchronously displayed through a transformation from the received data to displaying positions and pressure values. Finally, in the computer device, a document recording the handwriting track over time is created. The document can be a picture, a video, or even a document with audio.

Abstract: An electronic writing apparatus is provided. The electronic writing apparatus includes a cholesteric liquid crystal writing tablet, a trace recording unit, a processing module and a transmission interface. The cholesteric liquid crystal writing tablet has a writing/display surface for receiving a writing pressure to display writing trace according to a motion path of the writing pressure. The trace recording unit is disposed on a side of the cholesteric liquid crystal writing tablet opposite to the writing/display surface for detecting a position coordinate of the writing pressure. The processing module is electrically connected to the trace recording unit, and the processing module receives and converts the position coordinate to a writing data corresponding to the writing trace. The transmission interface is electrically connected to the processing module, and the writing data is transmitted to and stored in a cloud computing system or an external electronic apparatus through the transmission interface.
