Claims (10)

  1. 一種電子裝置，包括：一觸控板；一驅動單元，耦接至該觸控板，該驅動單元以一掃描頻率驅動該觸控板，以讀取在該觸控板的一觸碰座標；以及一處理單元，耦接至該驅動單元，其中當該電子裝置的一週邊元件被致能或被連接至該電子裝置時，該處理單元依據該週邊元件的特性資訊查找一工作頻率表而獲得該週邊元件的一頻率資訊，以及依據該週邊元件的該頻率資訊決定是否變更該驅動單元的該掃描頻率，其中當該週邊元件的特性資訊未登錄於該工作頻率表，且該驅動單元的該掃描頻率受該週邊元件干擾時，該處理單元使用一跳頻操作變更該驅動單元的該掃描頻率以尋找不受該週邊元件干擾的頻帶，以及將該週邊元件的特性資訊登錄於該工作頻率表。
  2. 如申請專利範圍第1項所述之電子裝置，其中該驅動單元依據一工作頻率設定而決定該掃描頻率，該處理單元依據該週邊元件的該頻率資訊決定是否變更該驅動單元的該工作頻率設定。
  3. 如申請專利範圍第2項所述之電子裝置，其中當該週邊元件被禁能或被拔除時，該處理單元將該工作頻率設定回復為一初始默認值。
  4. 如申請專利範圍第1項所述之電子裝置，其中當該驅動單元的該掃描頻率與該週邊元件的該頻率資訊相衝突時，該處理單元變更該驅動單元的該掃描頻率。
  5. 如申請專利範圍第1項所述之電子裝置，其中該週邊元件包括一充電器或一高解析度多媒體介面元件。
  6. 一種電子裝置的觸控板操作方法，包括：由一驅動單元以一掃描頻率驅動一觸控板，以讀取在該觸控板的一觸碰座標；當該電子裝置的一週邊元件被致能或被連接至該電子裝置時，依據該週邊元件的特性資訊查找一工作頻率表而獲得該週邊元件的一頻率資訊；依據該週邊元件的該頻率資訊決定是否變更該驅動單元的該掃描頻率；以及當該週邊元件的特性資訊未登錄於該工作頻率表，且該驅動單元的該掃描頻率受該週邊元件干擾時，使用一跳頻操作變更該驅動單元的該掃描頻率以尋找不受該週邊元件干擾的頻帶，以及將該週邊元件的特性資訊登錄於該工作頻率表。
  7. 如申請專利範圍第6項所述電子裝置的觸控板操作方法，更包括：依據該週邊元件的該頻率資訊決定是否變更該驅動單元的一工作頻率設定；以及依據該工作頻率設定而決定該驅動單元的該掃描頻率。
  8. 如申請專利範圍第7項所述電子裝置的觸控板操作方法，更包括：當該週邊元件被禁能或被拔除時，將該工作頻率設定回復為一初始默認值。
  9. 如申請專利範圍第6項所述電子裝置的觸控板操作方法，其中所述決定是否變更該驅動單元的該掃描頻率的步驟包括：當該驅動單元的該掃描頻率與該週邊元件的該頻率資訊相衝突時，變更該驅動單元的該掃描頻率。
  10. 如申請專利範圍第6項所述電子裝置的觸控板操作方法，其中該週邊元件包括一充電器或一高解析度多媒體介面元件。
