Abstract
A resistive touch control device and driving methods and a driving controller thereof are provided to switch operation modes of a touch panel. Depending on the user'"'"'s requirement, the touch panel can be operated in multi-touch mode or only in an analog mode with high resolution. In other words, the touch control device can be operated in a digital mode, the analog mode, or a hybrid mode including both of the digital and the analog modes.
