Specific embodiment
Fig. 1 and Fig. 2 is referred to, the first better embodiment of the invention provides a kind of electronic installation 100, and it can be mobile phone, personal digital assistant（Personal
Digital Assistant, PDA）Or palm PC etc..The electronic installation 100 includes main part 11, display unit 13, sensing unit 15 and processing unit 17.
The main part 11 includes first surface 111 and the second surface 113 being oppositely arranged with the first surface 111.The display unit 13 is arranged on the first surface 111 of main part 11, so that user browses information, for example, browses webpage or reading documents.In the present embodiment, the display unit 13 is touching display screen.Certainly, in other embodiments, the display unit 13 can also be light emitting display device, organic LED display device etc..
The sensing unit 15 is arranged on main part 11, the brightness of the surrounding environment light to sense the electronic installation 100, and the environmental light brightness for sensing is converted into into corresponding electric signal output to processing unit 17.The signal of telecommunication characterizes the brightness of the ambient light that the sensing unit 15 is sensed, i.e. the change of the size of the value of the signal of telecommunication represents the change of the brightness of the ambient light that sensing unit 15 is sensed.In the present embodiment, the value of the signal of telecommunication senses that the brightness of ambient light is proportional with sensing unit 15, i.e. the brightness of the ambient light that sensing unit 15 is sensed is bigger, and the value of the signal of telecommunication of its output is bigger.Certainly, in other embodiments, the value of the signal of telecommunication can sense the brightness of ambient light in inverse ratio with sensing unit 15, i.e. the brightness of the ambient light that sensing unit 15 is sensed is bigger, and the value of the signal of telecommunication of its output is less.
The processing unit 17 can be central processing unit（central processing
Unit, CPU）.The processing unit 17 is electrically connected with the sensing unit 15, to analyze and process the signal of telecommunication that the sensing unit 15 is transmitted, and be compared the electric signal output result and a preset value, and the first function or second function different from first function are performed according to the comparative result.
In the present embodiment, the processing unit 17 can also judge the surrounding brightness of the electronic installation 100 and whether have object closer or far from the electronic installation 100 according to the comparative result.Specifically, when the processing unit 17 is according to the comparative result（It is described in detail below）When judgement has object closer or far from the electronic installation 100, the sensing unit 15 can be used as a proximity transducer（proximity sensor）, the first function of execution of the processing unit 17.If the processing unit 17 judges not having object closer or far from the electronic installation 100 according to the comparative result（For example only the surrounding brightness of the electronic installation 100 changes）When, the sensing unit 15 performs the second function as common optical sensor, the processing unit 17.In the present embodiment, first function is the switching function of display unit 13.For example when the processing unit 17 judges there is object near the display unit 13（Such as user calls or receives calls）When, the display unit 13 is closed, to save electricity；And when the processing unit 17 judges the object away from the display unit 13, display unit 13 is opened, in order to the user operation display unit 13.Second function is the adjustment brightness function of display unit 13, i.e., the screen intensity of described processing unit 17 can be detected according to the sensing unit 15 the surrounding environment light brightness adjustment display unit 13.
In the present embodiment, the sensing unit 15 includes an induction apparatuss 151, and the induction apparatuss 151 are electrically connected with the processing unit 17.The induction apparatuss 151 are sent to processing unit 17 to sense the brightness of the surrounding environment light of the electronic installation 100, and the environmental light brightness for sensing is converted into into the corresponding signal of telecommunication.The processing unit 17 is compared the electric signal output value and a preset value, and performs corresponding first function or the second function according to comparative result.For example, when the processing unit 17 senses the output valve of the induction apparatuss 151, the value of the signal of telecommunication for exporting, decrement in a Preset Time is more than or equal to a preset value, such as user is because dialing or receiving calls and its head blocks the induction apparatuss 151, during so that the value of the signal of telecommunication of the output of the induction apparatuss 151 being reduced, judgement has object near the display unit 13.When the processing unit 17 senses incrementss of the output valve of the sensing unit 15 in the Preset Time more than or equal to the preset value, for example after user hangs up the telephone, its head is away from the sensing unit 15, during so that the value for sensing the signal of telecommunication that unit 15 is not blocked and exports increasing, judge the object away from the display unit 13.Now, used as a proximity transducer, the processing unit 17 performs first function to the sensing unit 15, i.e., when the processing unit 17 judges to have object near the display unit 13, the display unit 13 is closed, to save electricity；And when the processing unit 17 judges the object away from the display unit 13, the display unit 13 is opened, in order to the user operation display unit 13.
When the processing unit 17 judges that the output valve of the induction apparatuss 151 is unsatisfactory for above-mentioned condition, when i.e. described processing unit 17 judges that variable quantity of the output valve of the sensing unit 15 in the Preset Time is less than the preset value, the processing unit 17 judges not having object closer or far from the display unit 13, the sensing unit 15 is used as common optical sensor, the processing unit 17 performs the second function, i.e., the screen intensity of described processing unit 17 is detected according to the induction apparatuss 151 the surrounding environment light brightness adjustment display unit 13.
