Description

technical field [0001] The invention relates to touch sensing technology, in particular to a capacitive touch sensing device and a touch display device. Background technique [0002] As an input medium, a touch screen provides users with better convenience than a keyboard and a mouse. As an interface for user interaction, the touch screen has a long history of being integrated into LCD and other display panels. Touch screens include resistive, capacitive, surface acoustic wave, infrared, and so on. Due to cost reasons, resistive touch screens are still widely used at present. The driving principle of the resistive touch screen is to use the method of voltage drop to find the coordinates of the contact point. This type of touch screen requires the user to apply a certain pressure to make the upper and lower conductive planes conduct at a certain point to form a conduction loop. By detecting the The voltage change of the point determines its position, and multi-touch cannot ...
