Specific embodiment
Below in conjunction with the specific embodiment of the description of the drawings present invention.
As shown in figure 1, one embodiment of mobile phone of the present invention includes：
Infrared optical sensor 110；
Infrared optical sensor is the electronic component to infrared ray responsive, and its electrical parameter can show under infrared ray radiation
Write change.One common example is infrared photoresistor.Infrared photoresistor is made up of quasiconductor, the conductive capability of quasiconductor
Depending on semiconductor conduction band carriers number number, when photoconductive resistance be subject to illumination when, the Electron absorption photon in valence band
Conduction band is transitted to after energy, becomes free electron, while producing hole, the appearance of electron-hole pair makes resistivity diminish.Illumination
Stronger, photo-generate electron-hole is to more, and resistance is just lower.After photoconductive resistance two ends add voltage, photoconductive resistance is flow through
Electric current increases with illumination and increases.Incident illumination disappears, and electron-hole pair is gradually combined, and resistance also gradually recovers initial value, electric current
It is gradually reduced.
Light guide structure 115, its opening is located near touch screen, for directing the light to infrared optical sensor 110；
Light guide structure 115 can be the structure of any permeable light, and simplest situation is an aperture, it is also possible to
Transparent material, such as transparent plastic are covered on aperture.The opening of light guide structure 115 is in the vicinity of touch screen, it is preferred that be located at
The top of touch screen, can so avoid the interference of handss.Can be between the opening and infrared optical sensor 110 of light guide structure
There are light-guide device, such as light guide sheet, optical fiber etc..
Detector unit 120, for detecting that the electrical parameter of infrared optical sensor 110 changes；
For example, when infrared optical sensor 110 is specially infrared photoresistor, detector unit 120 is used to detect its resistance
The change of value.One exemplary circuit is as shown in Fig. 2 one end ground connection of infrared photoresistor R1, the other end imposes biased electrical
Pressure VCC, infrared photoresistor R1 adds one end of bias voltage in parallel with the input of analog-digital converter ADC, analog-digital converter ADC
Outfan be then connected with control unit 130.The voltage drop at analog-digital converter collection infrared photoresistor R1 two ends, the pressure drop
Reflect the resistance of infrared photoresistor R1.It is of course also possible to be connected in parallel on infrared photosensitive electricity with the device of a measurement resistance
Resistance two ends, by the resistance for measuring control unit 130 is input into.
Control unit 130, for being touched according to the electrical parameter of the infrared optical sensor 110 for measuring change locking or unblock
Touch screen.
Specifically, when the electrical parameter change of infrared optical sensor 110 shows to have the close touch screen of infrared radiation source, locking
Touch screen, is allowed to trigger, otherwise then unlocks touch screen.For example, when infrared optical sensor 110 is specially infrared photoresistor
When, when its resistance is less than default threshold value, the close touch screen of infrared radiation source is illustrated, the now locking of control unit 130 touch screen.
Sometimes, when mobile phone exposure is under sunlight, infra-red radiation is very strong, or may have and do not launch strong ultrared thing
The close touch screen of body (such as felt pen), may cause false-lock to determine, for this purpose, in another embodiment of the present invention, above-mentioned handss
Machine also includes：
Visible light-sensitive element 140；Light guide structure 115 is additionally operable to direct the light to visible light-sensitive element 110；Detector unit 120
It is additionally operable to detect the electrical parameter change of visible light-sensitive element 140；Control unit 130, specifically for according to the infrared light for measuring
The electrical parameter change of quick element 110 and the electrical parameter change locking of visible light-sensitive element 140 unlock touch screen.
Visible light-sensitive element is the electronic component sensitive to visible ray, and under visible light illumination its electrical parameter can show
Write change.One common example is visible light-sensitive resistance, and its characteristic is similar to infrared photoresistor, light guide structure 115 and inspection
Survey unit 120 also similar with aforementioned infrared optical sensor with the connection of visible light-sensitive element 140, do not repeat herein.
Visible light-sensitive element 140 can indicate the light intensity for being irradiated to touch screen, and control unit 130 is according to infrared photosensitive
The electrical parameter change locking of element 110 and visible light-sensitive element 140 unlocks touch screen.Specifically, when infrared photosensitive
The electrical parameter change of element 110 shows there is the close touch screen of infrared radiation source, while the electrical parameter change table of visible light-sensitive element
When the bright visible ray for being irradiated to touch screen is weak, touch screen is locked, be allowed to trigger, otherwise then unlock touch screen.For example, it is hot
Outer light-sensitive element 110 is specially infrared photoresistor, it is seen that when light-sensitive element 140 is specially visible light-sensitive resistance, work as infrared light
When quick resistance is higher than default threshold value less than default threshold value and visible light-sensitive resistance, illustrate that infrared radiation source is close to tactile
Screen is touched, while infrared source shield touch screen, the now locking of control unit 130 touch screen.
Using this embodiment, very strong in infra-red radiation or without strong infra-red radiation object proximity can be prevented effectively from and touched
False-lock determines touch screen in the case of touching screen, and preferably ensureing will not false triggering when the close touch screen of human body large area.
It will be understood by those skilled in the art that visible light-sensitive element 140 can share one with infrared optical sensor 110 leading
Photo structure 115, in addition it is also possible to the two is connected respectively with a light guide structure.Equally, detector unit 120 can include same
Individual physical device is respectively used to detect that visible light-sensitive element 140 can change with the electrical parameter of infrared optical sensor 110, also may be used
To be respectively used to detect that visible light-sensitive element 140 can join with the electricity of infrared optical sensor 110 including different physical devices
Number change, does not limit this present invention.Additionally, above-mentioned mobile phone also need not be realized locking and unlocked simultaneously, it can be only realized
