Abstract:
1. A touch sensing method, adapted to a resistive type touch apparatus, wherein the resistive type touch apparatus comprises: a touch panel comprising: a driving circuit, configured to set the resistive type touch apparatus to operate in a digital mode or in an analog mode, the driving circuit being coupled to the first electrodes, the second electrodes, the third electrodes, and the fourth electrodes, wherein overlapping portions between the first conductive patterns and the second conductive patterns are defined as a plurality of sensing blocks, and the touch sensing method further comprises: selecting an operation mode, such that the resistive type touch apparatus operates either in a single-touch mode or in a multi-touch mode; when the resistive type touch apparatus operates in the single-touch mode, the driving circuit activating a first analog scan and sensing function; when the resistive type touch apparatus operates in the multi-touch mode, the driving circuit activating either a second analog scan and sensing function or a digital scan and sensing function; and when the digital scan and sensing function is activated and the driving circuit senses that one of the sensing blocks is touched, the driving circuit then activating the first analog scan and sensing function.
