請參考第2圖，第2圖為本發明觸控感應面板的示意圖。如第2圖所示，本發明觸控感應面板200係電連接至一外部電子裝置300(例如一手持式電子裝置)。本發明觸控感應面板200包含一感應板210用以根據感測到之觸控位置產生觸控訊號，及一處理器220電連接於感應板210。處理器220包含一類比數位轉換器222，一輸出入介面224，一隨機存取記憶體226，及一處理單元230。類比數位轉換器222係用以將感應板210產生之觸控訊號從類比形式轉換為數位形式。隨機存取記憶體226可為為一靜態隨機存取記憶體。相異於先前技術的係，隨機存取記憶體226除了用以儲存數位化之觸控訊號外，隨機存取記憶體226亦會於外部電子裝置300開機後經由輸出入介面224從外部電子裝置300之一記憶體320下載和儲存觸控感應面板200運作時所需之操作程式322。之後，處理單元230再執行觸控感應面板200之操作程式322以根據隨機存取記憶體226儲存之觸控訊號產生一輸出訊號，並將輸出訊號經由輸出入介面224傳送至外部電子裝置300之一處理器310。外部電子裝置300之處理器310再根據處理單元230傳來之輸出訊號以及記憶體320儲存之操作程式324進行運作。Please refer to FIG. 2 , which is a schematic diagram of the touch sensing panel of the present invention. As shown in FIG. 2, the touch sensing panel 200 of the present invention is electrically connected to an external electronic device 300 (for example, a handheld electronic device). The touch sensing panel 200 includes a sensor board 210 for generating a touch signal according to the sensed touch position, and a processor 220 electrically connected to the sensor board 210. The processor 220 includes an analog-to-digital converter 222, an output interface 224, a random access memory 226, and a processing unit 230.

在上述流程圖400中，步驟440至步驟460係於步驟430之後執行，然而在本發明其他實施例中，步驟440至步驟460可於步驟420之手持式電子裝置300進行初始化時開始執行。In the above-described flowchart 400, the steps 440 to 460 are performed after the step 430. However, in other embodiments of the present invention, the steps 440 to 460 may be performed when the handheld electronic device 300 of step 420 performs initialization.
相較於先前技術，本發明觸控感應面板之啟動方法係將觸控感應面板運作時所需之操作程式儲存於外部電子裝置之非揮發性記憶體內，當外部電子裝置被開啟時，觸控感應面板之處理器之隨機存取記憶體再從外部電子裝置之記憶體下載和儲存觸控感應面板運作時所需之操作程式，以供觸控感應面板之處理單元執行操作程式。因此本發明觸控感應面板之處理器不需要快閃記憶體(或其他非揮發性記憶體)來儲存觸控感應面板運作時所需之操作程式，進而使本發明觸控面板之功率消耗減少。請參考表1，表1為16千位元組之快閃記憶體與隨機存取記憶體之比較表。快閃記憶體製造程序也較複雜，排除此快閃記憶體的部分也同時降低製造成本及功率消耗。Compared with the prior art, the touch sensing panel is activated in the non-volatile memory of the external electronic device when the external electronic device is turned on. The random access memory of the processor of the sensing panel downloads and stores the operation program required for the operation of the touch sensing panel from the memory of the external electronic device for the processing unit of the touch sensing panel to execute the operating program. Therefore, the processor of the touch sensing panel of the present invention does not require flash memory (or other non-volatile memory) to store the operation program required for the operation of the touch sensing panel, thereby reducing the power consumption of the touch panel of the present invention. . Please refer to Table 1. Table 1 is a comparison table of flash memory and random access memory of 16 kilobytes.
