Description

觸控顯示裝置及其複數條觸控驅動電極的驅動方法 Touch display device and driving method of touch driving electrodes

許多觸控螢幕可藉由將電容性觸控面板覆蓋於液晶顯示器(Liquid Crystal Display；LCD)上形成。此觸控螢幕輸出驅動訊號至複數條觸控驅動電極，及自複數條觸控感測電極接收感測訊號。當至少一外部物件觸碰或接近觸控驅動電極與觸控感測電極的交叉點附近時，該觸控驅動電極與該觸控感測電極之間的電容將改變。觸控螢幕即可根據此一電容改變判斷發生觸碰的位置。 Many touch screens can be formed by covering a capacitive touch panel on a Liquid Crystal Display (LCD). The touch screen outputs driving signals to a plurality of touch driving electrodes, and receives sensing signals from the plurality of touch sensing electrodes. When at least one external object touches or approaches the intersection of the touch driving electrode and the touch sensing electrode, the capacitance between the touch driving electrode and the touch sensing electrode will change. The touch screen can change the position where the touch occurs according to this capacitance change.

In addition, the capacitive touch panel covering the liquid crystal display further increases the thickness and weight. However, although the integration of the touch screen assembly into the liquid crystal display can avoid the above problems, the electromagnetic interference (EMI; ElectroMagnetic Interference) generated by the liquid crystal display when the screen is updated will affect the touch driving electrode and the touch sensing electrode The amount of mutual capacitance coupling.
