ABSTRACT:
An electronic pen device is proposed, which can be coupled to a computer platform having a display unit and an input-sensing unit, allowing a user to manually input data and/or graphs to the computer platform via the electronic pen device. The electronic pen device includes a micro-processing unit (MPU), a storage unit for storing color-corresponding codes, an input unit for allowing the user to set a display color for the handwriting data and/or graphs to be displayed on the display unit, and a signal output module. The MPU retrieves a color-corresponding code from the storage unit corresponding to the set display color and sends a color signal corresponding to the color-corresponding code to the signal output module that further sends the color signal to the computer platform. The display unit then displays the handwriting data and/or graphs in the set display color responsive to the color signal.
