Description
本發明是有關於觸控感測面板技術，特別是一種觸控感測顯示面板。The invention relates to a touch sensing panel technology, in particular to a touch sensing display panel.
內嵌式觸控感測面板(in-cell touch)經常採用的觸控感測單元係由電容式觸碰感測器與後端處理電路所組成，其中電容式觸碰感測器係用來感測使用者之觸碰，而後端處理電路則依據電容式觸碰感測器的輸出訊號來進行觸碰事件(touch event)的判讀。然而，在目前的結構中，電容式觸碰感測器將會與面板的像素陣列(或稱主動元件陣列基板)有大面積的重疊，因而造成寄生電容變大而降低電容式觸碰感測器的感應靈敏度。The touch-sensing unit often used in in-cell touch is composed of a capacitive touch sensor and a back-end processing circuit. The capacitive touch sensor is used to The touch of the user is sensed, and the back-end processing circuit judges a touch event based on the output signal of the capacitive touch sensor. However, in the current structure, the capacitive touch sensor will have a large area overlap with the pixel array (or active element array substrate) of the panel, which will increase the parasitic capacitance and reduce the capacitive touch sensing. Sensor's inductive sensitivity.
現今有對電容式觸碰感測器與主動元件陣列基板輸出同驅波形以降低寄生電容的方式。輸出同驅波形的作法在理想上係可完全減去降生電容數值，然而在實際應用上，面板的遠近端的阻容負載(RC Loading)的差異會造成訊號送至電容式觸碰感測器和主動元件陣列基板的遠端後波形無法完全一致，遠近端阻容負載的不匹配將造成其效果不佳。At present, there are ways to reduce the parasitic capacitance by outputting the same driving waveform to the capacitive touch sensor and the active element array substrate. The method of outputting the same drive waveform ideally can completely reduce the value of the degeneration capacitor. However, in practical applications, the difference between the RC loading at the far and near ends of the panel will cause the signal to be sent to the capacitive touch sensor and The waveform at the far end of the active element array substrate cannot be completely consistent, and the mismatch between the far-end and near-end resistance-capacitance loads will cause its poor effect.
為了改善上述的缺憾，本發明提供一種觸控感測顯示面板，包括：觸控感測層、主動元件陣列基板及開關單元。觸控感測層包含複數個觸控感測單元，每一觸控感測單元電性連接一導電線。主動元件陣列基板與觸控感測層相對設置，且主動元件陣列基板包括複數個資料線。開關單元包含複數個開關，各開關之一端電性連接此些導電線之至少其中之一，另一端電性連接此些資料線之至少其中之一。其中，在觸控感測感測期間，開關處於導通狀態。In order to improve the above disadvantages, the present invention provides a touch-sensing display panel, which includes a touch-sensing layer, an active element array substrate, and a switch unit.

The switch unit includes a plurality of switches. One end of each switch is electrically connected to at least one of the conductive lines, and the other end is electrically connected to at least one of the data lines.
