Description
Technical field
The present invention relates to a kind of is the method and mobile terminal reminded before mobile terminal touch screen is scratched.
Belong to mobile terminal touch screen prevention area.
Background technology
At present, although the material that the touch screen on market uses is increasingly advanced, but mobile phone is placed on pocket
In still have situation about being much scratched, as key and mobile phone are placed in pocket simultaneously, be just likely to exist
Leaving cut above screen, this is owing to the hardness of touch screen cannot be with metal ratio.
Chinese Patent Application No. is 201010002215.9 to disclose a kind of prevention mobile terminal touch screen
The method damaged and relevant apparatus, after being characterized in detecting that touch screen comes in contact event, then determine
Whether this contact event can cause touch screen from being damaged, when confirming that this contact event is damaged, performs predetermined
The measure of prevention touch screen from being damaged；Wherein, " whether detection touch screen comes in contact event " basis
In touch screen structure, the level change of conductive layer detects；" determine whether this contact event can cause
Touch screen from being damaged " whether can enter more than the first predetermined value according to contact point unit are average pressure value
Row judges, it is also possible to the number of times being consecutively detected contact event according to the detection cycle is the most pre-more than second
Definite value judges；" perform the measure of predetermined prevention touch screen from being damaged " and mobile terminal can be used
Audio chip send and prevent the warning tone of touch screen from being damaged measure from carrying out for reminding user to take
Prevention, it would however also be possible to employ the vibrations device vibrations of mobile terminal, makes mobile terminal change current location and enters
Row prevention.But this application is just for the detection of contact event, not to mobile terminal local environment
Automatically carrying out anticipation, such as mobile terminal in open environment is to detect contact event
, accordingly, it would be desirable to the detection of always on contact event, if there is unnecessary prompting, it will
Use to mobile phone users brings inconvenience, and does not also have corresponding technology to open in this application file
Show.
Summary of the invention
The invention aims to solve the defect of above-mentioned prior art, it is provided that a kind of mobile terminal touches
Touching the method for prompting before screen is scratched, the method can first detect touch screen status, touches in confirmation

Following steps:
S1, unlatching proximity transducer；
The infra-red intensity and first that the infrared receiving tube of S2, relatively sensor receives sets threshold
Size between value 1000, if infra-red intensity is more than 1000, touch screen is in object proximity state,
During i.e. mobile terminal is in the environment of closing, as being in trousers pocket and pocket, perform S4；
The infra-red intensity and second that the infrared receiving tube of S3, relatively sensor receives sets threshold
Size between value 500, if infra-red intensity is less than 500, touch screen is in object away from state,
During i.e. mobile terminal is in open environment, do not carry out any operation；
S4, when touch screen is in object proximity state, detected whether touch event；
S5, when detection has touch event, according to touch information judge touch magnitude range the least
Whether it is more than touch screen maximum pressure setting value in range set value (20,20) and touch pressure value
255, if the magnitude range touched is less than (20,20), and touch pressure value is more than 255, determines that this touches
The event of touching will scratch touch screen, i.e. illustrate that contact point now is less, in fact it could happen that sharp-pointed metal object
Body (owing to metal object is capacitive character material, can cause the change of touch screen electric capacity) is with bigger
Pressure extrusion touch screen；
S6, determine this touch event will scratch touch screen time, utilize the tinkle of bells remind user prevent touch
Screen is scratched.
In the present embodiment, in step s 2, when touch screen is in object proximity state, the reddest
If outer line strength drops to less than 1000 more than 500, still can be in object proximity state；In step
In rapid S3, when touch screen is in object away from state, if now infra-red intensity rises to 500
When above less than 1000, still can be in object away from state；Touch information described in step S5 includes sitting
