| 20120013633 | POSITIONING METHOD AND DISPLAY SYSTEM USING THE SAME - A positioning method for obtaining position where a light pen is in contact with a display device at a to-be-positioned spot is provided. The display device includes display areas, corresponding with positioning coding patterns of a built-in positioning frame. The positioning method includes the following steps. Firstly, a positive positioning frame and a negative positioning frame are obtained according to the built-in positioning frame. Next, the positive and the negative positioning frames are respectively added on first original video frames to respectively generate first frame displayed in first frame time and second frame displayed in second frame time. Then the light pen obtains first selected image and second selected image from the first and the second frames respectively. After that, a to-be-positioned pattern is obtained by subtracting the second selected image from the first selected image and a coordinate position of the to-be-positioned spot is obtained. | 01-19-2012 |
