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 light sensor value whether from one close to zero value change to a larger value, namely detect touch-screen and whether leave from certain body surface.
(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:
Does 101) utilizing on described light sensors touch-screen have object to leave? (that is: detect light sensor value from one close to zero value change to a larger 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 101) described in light sensors to the variable quantity of value size need according to repeatedly test draw, can be specifically a numerical value of about 5;
