Multi-touch screen technology, human-computer interaction research based on multi-touch technology. The self-capacitive touch screen realizes the multi-touch recognition gesture direction, that is, only detects and distinguishes multi-touch behaviors, such as zooming, dragging, rotating, etc. The way is the axis interleaved technology.
It is a diamond shape sensing unit plan on the conductive layer, and each layer requires a conductive layer.
Taking the two-axis type as an example, when detecting the touch behavior, the sensing controller scans the horizontal axis and the vertical axis respectively, and the horizontal and vertical sensing points of the capacitive sticks will have rising peaks, the two-axis intersection is the touch point.
