Abstract:
1. A writing apparatus adapted for performing a writing operation on an electronic paper, said writing apparatus comprising: a writing controller including: a pixel array writing unit coupled electrically to said data driving unit and said scan driving unit, and adapted to be disposed to confront a first planar side of the electronic paper for performing the writing operation on the electronic paper as controlled by said writing controller, where the data signals are written into the electronic paper with reference to the scan signals so as to enable the electronic paper to display a corresponding image; a position detecting unit adapted for generating a positioning signal by detecting a positioning unit of the electronic paper, said writing controller being operable to initiate the writing operation when the positioning signal indicates that the electronic paper is properly placed relative to said pixel array writing unit; a physical driving unit adapted to physically move the electronic paper relative to the pixel array writing unit; and a position tuning unit coupled electrically to said position detecting unit and said physical driving unit for controlling said physical driving unit to physically move the electronic paper when the positioning signal generated by said position detecting unit indicates that placement of the electronic paper relative to said pixel array writing unit deviates from an ideal placement until the positioning signal indicates that the electronic paper is properly placed relative to said pixel array writing unit in order to permit initiating of the writing operation on the electronic paper.
