Description

觸控顯示面板Touch display panel

本發明是有關於一種觸控顯示技術，且特別是有關於一種觸控顯示面板。 The present invention relates to a touch display technology, and in particular, to a touch display panel.

內嵌式觸控(in-cell touch)面板(例如圖1的內嵌式觸控面板10)經常採用電容式觸控感測技術。此技術由使用在觸控面板上形成的多個觸控電極以基於觸控點與觸控電極之間的電容變化檢測觸控點的座標。然而，在目前的面板結構中，根據電容式觸控感測技術，除觸控感測需要的電容之外，其他圍繞觸控電極的電壓線或電極也會產生不必要的寄生電容，這將導致觸控操作的負載增加、觸控感測的準確性降低，並且在嚴重情況下，可能使觸控感測異常。 In-cell touch panels (such as the in-cell touch panel 10 of FIG. 1 ) often adopt capacitive touch sensing technology. This technology uses multiple touch electrodes formed on a touch panel to detect the coordinates of a touch point based on capacitance changes between the touch point and the touch electrodes. However, in the current panel structure, according to capacitive touch sensing technology, in addition to the capacitance required for touch sensing, other voltage lines or electrodes surrounding the touch electrodes will also generate unnecessary parasitic capacitance, which will This results in increased load on touch operations, reduced accuracy of touch sensing, and in severe cases, abnormal touch sensing.

現今有對資料線輸入觸控同驅訊號以降低寄生電容及觸控負載的方式。對資料線輸入觸控同驅訊號的作法在理想上可減去電容數值，然而在實際應用上，面板設計具修補線(repair line)以當資料線斷線時，將資料線與修補線進行熔接(welding)，讓用於驅動資料線的驅動訊號可通過運算放大器傳送到斷線的另一側。然而，修補線線路的阻容(RC)過大或是受到其他電路的耦合將導致修補後的資料驅動訊號與其餘的不同，此會造成該條資料線上方的觸控點與觸控電極之間的電容與其餘的不同而導致觸控訊號異常並嚴重影響觸控效能。 Nowadays, there are ways to input touch co-driver signals to the data lines to reduce parasitic capacitance and touch load. The method of inputting touch co-drive signals to the data line can ideally subtract the capacitance value. However, in practical applications, the panel is designed with a repair line to connect the data line and the repair line when the data line is disconnected. Welding allows the driving signal used to drive the data line to be transmitted to the other side of the broken line through the operational amplifier. side. However, if the resistance-capacitance (RC) of the repair line is too large or is coupled by other circuits, the repaired data drive signal will be different from the rest. This will cause a gap between the touch point and the touch electrode above the data line. The capacitance is different from the rest, causing abnormal touch signals and seriously affecting touch performance.
