Touchpad driving system and method

Abstract

The invention provides a touchpad driving system and method. The touchpad driving system comprises a touchpad controller, a touchpad driving program, an application program and a service resident program; the touchpad controller is coupled to a touchpad so as to correspondingly generate touch data for a touch gesture operation signal received on the touchpad; the touchpad driving program collectsthe touch data generated by the touchpad controller; the application program is responsible for setting touch gesture parameters; the service resident program is responsible for calling the application program and providing touch gesture processing. Therefore, with the touchpad driving system and the touchpad driving method adopted, gesture processing speed is not easy to delay, and touch smoothness can be improved; and when the system is abnormal and is restarted without power failure, the touchpad can still be used as a mouse without causing system crash.

Description

technical field [0001] The present invention relates to the technical field of touch panels, especially a touch panel driving system and method. Background technique [0002] Touch pads (touch pads) have gradually become standard equipment on various consumer electronics products and computer devices. With the development of touch sensing technology, the touchpad has also improved from only providing single-finger control function to various input functions with various touch gestures, which further increases the applicability of the touchpad . [0003] Since the touchpad is set on an electronic product such as a notebook computer as a hardware input device, it must be matched with a software driver to work properly, such as figure 1 Shown is to illustrate the driver framework of the conventional touch panel, wherein the touch panel 101 in the device hardware part is controlled by a touch panel controller 103, and the system software part then includes a touch panel driver...

AI Technical Summary

Problems solved by technology

[0004] With the driver architecture of the aforementioned touchpad, the processing of gestures and the like is the responsibility of the application program 106, and when the operating system is busy, the system priority of the application program 106 is low. Stopping the program 105 to re-call the application program 106, causing the touchpad 101 to respond slowly or not to be used, and because the application program 106 uses the Windows API (Application Programming Interface) to report the system will have a permission problem, so if the application program 106 accidentally Pausing will cause the touchpad 101 to be unusable

[0005] Therefore, the driver framework of the known touch panel still has some imperfections, and there is a need for improvement.
