Abstract
A single layer mutual-capacitive touch panel and a capacitive touchscreen are disclosed, which belong to the field of display technologies. The scanning frequency of a SITO and the accuracy in scanning a touch signal can therefore be improved. The single layer mutual-capacitive touch panel comprises a substrate and a plurality of touch units arranged in an array on the substrate, wherein each of the touch units includes a first sensing electrode for sensing a vertical coordinate of a touch signal, a second sensing electrode for sensing a horizontal coordinate of the touch signal, and a scanning electrode arranged close to the first sensing electrode and the second sensing electrode to form mutual capacitors therewith respectively.
