Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the schematic flow sheet of the preferred embodiment of the inventive method;
Fig. 2 is the schematic flow sheet of the preferred embodiment of step S3 in specific implementation Fig. 1.
Embodiment
As shown in Figure 1, the disposal route that a kind of capacitance touch screen of the present invention responds by mistake, comprises the following steps:
S1, determine touch-screen mistake response easy happen zone territory.In this step, first response easy happen zone territory (fault easy happen zone territory) by mistake will be found out, usually the data that the touch-screen by being shaped to detailed programs design obtains after debugging and testing, region capacitance touch display screen easily being reported (by mistake response) by external environmental interference by mistake can be determined, this wrong report is not for when user carries out any operation to touch display screen, the response that touch-screen is random, be generally ceaselessly continuous response, namely this region responds easy happen zone territory by mistake, by mistake response easy happen zone territory at least one, four folding corner regions of fault easy happen zone territory normally touch display screen, also can be the arbitrary region that on touch display screen, user usually operates.After next determines and responds easy happen zone territory by mistake, suitably can expand responding easy happen zone territory by mistake, comprise all wrong reports point as far as possible, then the response of the mistake after all suitable expansion easy happen zone territory is represented with two-dimensional coordinate, namely by [X0 between horizontal zone, X1] and vertical area between [Y0, Y1] indicate rectangle response easy happen zone territory by mistake, now coordinate (X can be used in this arbitrfary point by mistake in response easy happen zone territory
k, Y
j) represent.
S2, scan period T is set and allows the times N of continuous response.In this step, can according to the data for the testing inspection that carries out when determining by mistake response easy happen zone territory or multiple Consumer's Experience feedback in step S1, formulate scan period T, guarantee that the scan period T set is the minimum period that by mistake response (wrong report point) occurs for the mistake response easy happen zone territory of touch display screen, in case to the undetected survey of response by mistake and drain process.In order to not affect the normal operation of other application program of electronic equipment, can arrange a time T2 in addition, be the interval time of adjacent twice process, and so total cycle T 1 is actual treatment time T and the summation processing T2 interval time for twice.In addition the continuous response times N arranged in this step, for user touch display screen is operated time, the maximum times of the normal continuous response of touch display screen.
S3, in cycle T, described by mistake response easy happen zone territory to be scanned, calculate continuous response number of times, if continuous response number of times is greater than N, then perform step S4, no, then return step S3.Touch-control IC in electronic equipment can complete the conversion operations that capacitance variations and touch screen respond, and after effectively touching, (no matter being manual palpation or response by mistake) will be reported a little to upper strata.In this step, in time T, Scanning Detction is carried out to all fault easy happen zone territories, only scanning is with or without report point and report point quantity (corresponding response and response times), if after two-dimensional coordinate demarcation by mistake response easy happen zone territory, what only need detection failure area coordinate reports situation, if touch-screen response once, the coordinate in response easy happen zone territory can report about M time by mistake, M=m*t, wherein m is the report point rate of touch-control IC, and t is that touch-screen responds a required time.When occurring reporting the situation of coordinate more than M time continuously, calculate during this reports continuously the number of times reported.This number of times reported continuously exceedes preset times M*N, illustrates that break down in the region occurring to report continuously (by mistake response), performs step S4, if do not have, illustrates that this time reports continuously as the response under normal touch operation, enters the Scanning Detction in next cycle.
S4, recovery operation is carried out to touch-screen.The recovery operation carried out touch display screen in this step comprises to be forced to carry out reset operation to touch display screen or power down powers on again.Aforesaid operations can complete in several seconds, did not affect the normal use of user.
In a preferred embodiment of the invention, for concrete touch-screen, some rate m can be reported to be fixed on a scope.But in fact, a report point rate m is a parameter determined by touch-control IC, and can change as required, generally at about 80HZ, namely per secondly report coordinate 80 times.Further, it is 1 second that predeterminable touch-screen responds a required time t, report more than 4 seconds continuously for maloperation, so in step S2, allow the times N of continuous response can be set to 4, allow the times N * M=N*m*t=4x80x1=320 that coordinate (coordinate of identical point coordinate or difference) reports continuously.
If represent wrong response easy happen zone territory with two-dimensional coordinate, as shown in Figure 2, step S3 comprises the following steps:
S31, in cycle T, the coordinate in by mistake response easy happen zone territory is carried out by column or lined by line scan.
Whether S32, the coordinate detecting described by mistake response easy happen zone territory report more than M time continuously, if so, then calculate this number of times reported continuously, no, then return step S31.
If this number of times reported continuously of S33 is greater than M*N, then there is response by mistake, perform step S4, no, then return step S31.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present invention.
