TOUCH CONTROLLER, TOUCH SYSTEM, AND METHOD FOR DETECTING A TOUCH SCREEN |
| 摘要 |
The invention discloses a touch controller, a touch system, and a method for detecting a touch screen. At first, a full screen driven detection is performed on a touch screen to determine whether at least one external object touches or approaches the touch screen. Then, if the full screen driven detection represents that no external object touches or approaches the touch screen, an updating determination is performed to determine whether a plurality of reference values are updated during a predetermined updating period of time. If the updating determination represents that the reference values are not updated during the predetermined updating period of time, the reference values will be updated based on a first 2D sensing information. |

1. A method for detecting a touch screen, comprising:
performing a full screen driven detection on a touch screen to determine whether at least one external object touches or approaches the touch screen; performing an updating determination to determine whether a plurality of reference values are updated during a predetermined updating period of time if the full screen driven detection represents that no external object touches or approaches the touch screen; and updating the reference values based on a first 2D (two-dimensional) sensing information if the updating determination represents that the reference values are not updated during the predetermined updating period of time. |
