The present invention provides a method, a system, and an apparatus for processing a touch sensing signal, and an electronic device. The method is applied to an operating system and includes: receiving a touch sensing signal generated by a touch sensor of a touch device; converting the touch sensing signal to a touch signal, where the touch signal at least comprises a touch position signal; sending the touch signal to the touch device; receiving the touch signal coded by the touch device and transferring to a touch driver. In implementing the embodiments of the present invention, the touch sensing signal generated by the touch sensor is converted to the touch signal by the operating system followed and returned back to the touch device, and therefore the touch device do not need to perform conversion processing, which can reduce the performance requirement on its chip and lower the cost and volume of the touch device.
