402) number of times of touch-screen and control chip communication failure is added up, judge that failed number of times is lower than communication failure setting value? enter step 404), otherwise enter next step;
403) reset operation that re-powers after carrying out power-off of touch-screen, then return step 401);
404) do you judge that the region that antistatic impact ability is weak in touch-screen or touch-screen creates touch event? be enter next step, otherwise return step 401);
405) in setting-up time, detect the same area generation touch event total degree that touch event occurs and exceeded wrong report setting value? be enter next step, otherwise return step 401);
406) touch-screen carries out register software reset operation, then returns step 401).
According to touch-screen static elimination method provided by the invention, described step 401) comprise and detect gravity sensor z-axis value and whether change to from a value being less than "-8 " value that is greater than "+8 ".
According to touch-screen static elimination method provided by the invention, described step 402) in touch-screen to communicate with control chip be I2C(internal integrated circuit Inter-Integrated Circuit) bus communication.
According to touch-screen static elimination method provided by the invention, described communication failure setting value refers to the number of times of this I2C bus (probably going back other I2C equipment of carry) integrated communication failure, is specially 4-6 time.
According to touch-screen static elimination method provided by the invention, described setting-up time is 1 second, and described wrong report setting value is 60-80 time.
Touch-screen static elimination method provided by the invention, for when touch-screen is often subject to electrostatic influence, the touch-screen that can reset effectively is rapidly to recover normal use, and comparatively prior art has the following advantages:
1, when there is electrostatic breakdown to touch-screen to judge accurately;
2, to adopting which kind of reset measure effectively to control after touch-screen generation electrostatic breakdown;
3, avoid using obstacle, reset touch-screen is to recover normal use effectively rapidly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail further:
Fig. 1 is the static elimination program software schematic flow sheet on specific embodiment of the invention touch-screen smart mobile phone.
Embodiment
First, inventive concept and committed step are described:
(i) detect gravity sensor z-axis value whether from a value close to-9.8. change to one close to+9.8 value, in order to judge that touch-screen is from ventricumbent state turnover to supine state.Test according to applicant and prove that general this situation just easily produces electrostatic, and now carry out automatic static elimination process and at utmost can alleviate cpu load.
(ii) the number of times of touch-screen I2C communication failure is added up, judge that whether failed number of times is lower than communication failure setting value, if higher than communication failure setting value, illustrate that touch-screen I2C communicates repeatedly failed, so just carry out power-off and re-power reset again.
(iii) in setting-up time, whether the number of times detecting some region generation touch event has exceeded wrong report setting value, if exceeded wrong report setting value, illustrate and created unlimited touch event in this region of touch-screen, so register software reset has been carried out to touch-screen.
The second, be described in detail in conjunction with specific embodiments:
As shown in Figure 1, the static elimination program on specific embodiment of the invention touch-screen smart mobile phone specifically comprises the following steps:
101) gravity sensor is utilized to detect handheld device touch-screen from the state transfer that faces down for the state of facing up? (that is: detect gravity sensor z-axis value from a value close to-9.8. change to one close to+9.8 value?) be enter next step, otherwise return step 101);
102) number of times of touch-screen and control chip I2C communication failure is added up, judge that failed number of times is lower than communication failure setting value? be enter next step, otherwise enter step 104);
103) reset operation that re-powers after carrying out power-off of touch-screen, then return step 101);
104) do you judge that antistatic impact ability is weak in touch-screen region or other regions create touch event? be enter next step, otherwise return step 101);
105) in setting-up time, detect the same area generation touch event total degree that touch event occurs and exceeded wrong report setting value? be enter next step, otherwise return step 101);
106) touch-screen carries out register software reset operation, then returns step 101).
Wherein:
Step 102) described in the communication failure setting value of I2C communication failure counting need to draw according to electrostatic experimental test repeatedly, specifically can about 5 a numerical value;
Step 104) described in the touch event region that antistatic impact ability is weak on touch-screen hardware often produce;
Step 105) described in wrong report setting value when being less than touch-screen normal touch divided by setting-up time, the secondary numerical value that touch event per second reports can be specifically a numerical value of about 70.
Finally, the foregoing is only preferred embodiment of the present invention, all equalizations done according to the claims in the present invention scope change and modify, and all should belong to the covering scope of the claims in the present invention.
