Abstract: A touch device includes a touch sensing unit, a processing unit, an embedded controller and a digital controller. The touch sensing unit has a first control mode and a second control mode, and senses a touch event from a touch stylus. The embedded controller is coupled to the processing unit. The digital controller is coupled to the touch sensing unit, the embedded controller and the processing unit, and receives a general-purpose input/output (GPIO) signal from the embedded controller. When the GPIO signal is in a first value, the digital controller reports the first control mode to the processing unit. When the GPIO signal is in a second value, the digital processor reports the second control mode to the processing unit. Thus, the performance of the touch device and the touch stylus is improved.

Abstract: A touch display method is configured for an electronic apparatus including a touch display module and an embedded controller. The touch display module includes a touch display device and a touch input controller. The method includes following steps: loading a BIOS to perform an initialization operation when the electronic apparatus has not loaded an operating system; defining a virtual input area in the touch display device; and further displaying an input interface on the virtual input area. Generate a touch event when the touch display device is touched and translate the touch event into a coordinate by the touch input controller. If the coordinate is in the input interface, the touch input controller outputs a function signal to the embedded controller through the hardware interface. The embedded controller translates the function signal into a scan code for the electronic apparatus to execute operations corresponding to the scan code.
