Technical Field
The invention relates to the technical field of display, in particular to a touch device and a touch substrate.
Background
Due to the high durability, long service life and the function of supporting multi-point touch control, the capacitive touch screen is widely applied to various electronic interaction scene devices. The capacitive touch screen detects the specific position touched by the finger by detecting the capacitance change at the position touched by the finger. Therefore, when the amount of capacitance change caused when touched is small, the conventional capacitive touch screen may not accurately detect whether there is a touch input.
The existing capacitive touch device is realized by two layers of touch driving electrodes and touch sensing electrodes which are intersected in different surfaces, and the working process is as follows: when a touch driving signal is loaded on the touch driving electrode, a voltage signal coupled by mutual capacitance between the touch sensing electrode and the touch driving electrode acts on the mutual capacitance when a human body contacts the touch screen, so that the capacitance value of the mutual capacitance changes, the voltage signal coupled by the touch sensing electrode is further changed, and the position of a contact can be determined according to the change of the voltage signal. However, the mutual capacitance induction quantity between the touch driving electrode and the touch sensing electrode of the existing capacitive touch screen is small, so that the capacitance change caused by the touch of a human body is small, and the touch precision of the touch device is low.
Therefore, a new technical solution is needed to solve the above technical problems.
