Abstract

The invention relates to a signal processing method for a combined type touch-control panel, which is used for receiving a first touch-control signal emitted by a first interface and a second touch-control signal emitted by a second interface simultaneously. The method comprises the following steps of: firstly, obtaining an effective trigger area of the touch-control panel, setting a first mode block and a second mode block on the effective trigger area, and obtaining a trigger point generated by the first interface or the second interface on the effective trigger area; and secondly, judging a touch-control signal and a touch-control position of the trigger point, and if determining that the trigger point is an effective point, executing a first mode or a second mode correspondingly according to the position where the trigger point is positioned.

Description

technical field [0001] The invention relates to a signal processing method of a touch panel, in particular to a signal processing method of a composite touch panel. Background technique [0002] In recent years, with the rise of information appliance (IA) products, such as mobile phones, digital cameras, satellite navigation and positioning devices (global positioning system, GPS), or personal digital assistants (personal digital assistant, PDA) and other portable electronic Devices are becoming more and more popular, and such information home appliances are constantly being developed towards the direction of easy operation, small size and large screen size, especially consumers have stricter requirements on the size and screen size of portable electronic products. As the current production cost of touch panels has been greatly reduced, many consumer electronics products integrate touch panels with liquid crystal display panels, and replace existing computer peripheral devic...
