Detailed description of the invention
It is described in detail referring to the drawings below in conjunction with embodiment, in order to technical characteristic and advantage to the present invention are interpretated more in-depth.
The method flow diagram of the present invention, as it is shown in figure 1, a kind of touch-screen anti-interference method, the described electromagnetic interference that interference is LCD, comprises the following steps:
Step 1. touch-screen reports the touch point touching area less than systemic presupposition threshold values；
Step 2. starts timer, arranges touch point acquisition time；
Step 3. is the data of the touch point of collection touch in arranging the time, including the area of coordinate value, force value and the touch point of touch point；
The data gathered are compared by step 4., and whether the data that interpretation gathers, in default excursion, are then to perform step 5, otherwise perform step 7；
Step 5. judges whether the area gathering data touch point is both less than systemic presupposition threshold values, is then to perform step 6, otherwise performs step 7；
Step 6. currently disturbs the electromagnetic interference for LCD, and touch-screen carries out reset processing；
Step 7. touch-screen enters normal operating.
Further, the area-limit of the touch point that systemic presupposition threshold values is systemic presupposition described in step 1, exceed threshold values and then touch for user's normal operating, be otherwise the electromagnetic interference point of LCD.
Further, the touch point described in step 2 gathers and reports the touch point touching area less than systemic presupposition threshold values for collection touch.
Further, the acquisition time described in step 2 is definite value, cannot respond to, for touch-screen, the time that normal finger touches, adjusts by systemic presupposition or by user.
Further, the default excursion of the data of the collection described in step 4 is definite value, adjusts by systemic presupposition or by user, when being then the electromagnetic interference point of LCD in this excursion, otherwise touches for user's normal operating.
Further, the reset processing described in step 6 re-powers after being power-off and resets.
The terminal device theory diagram of the present invention as in figure 2 it is shown, the terminal device of a kind of described touch-screen anti-interference method, including:
Detector unit, is less than the touch point of systemic presupposition threshold values for detecting the area that touches on touch-screen, and reports CPU；
Timer, for arranging the acquisition time gathering touch point；
