Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

Embodiment mono-

The embodiment of the present invention provides a kind of method of controlling screen state, is applied to comprise and as shown in Figure 1, comprising the terminal that approaches optical sensor:

101, obtain and approach the sampled value that optical sensor gathers.

Wherein, described sampled value by approach that optical sensor collects by periodic transmitting infrared light sampled value, the sampled value of described collection and terminal screen are corresponding to the distance between barrier.Terminal screen is far away to the distance between barrier, and described sampled value is less, and terminal screen is nearer to the distance between barrier, and described sampled value is larger.It should be noted that, the described sampled value that approaches optical sensor collection is stored in the register that approaches optical sensor.

102,, according to the first pre-stored definite value and the sampled value of described collection, the first pre-stored reference value is adjusted into more approaching for judging whether that terminal is away from sampled value corresponding to the critical distance of barrier.

Wherein, described the first definite value is a fixing value, inventor found through experiments, the sampled value of the multiple terminals that built-in same type approached to optical sensor during apart from barrier same distance made comparisons, the sampled value of each terminal is different, but the multiple terminals that built-in same type approached to optical sensor are made comparisons with the difference of the sampled value apart from barrier same distance b apart from barrier same distance a, the terminal that approaches optical sensor of each built-in same type is that the difference that sampled value that a is corresponding is the sampled value that b is corresponding with the distance apart from barrier is identical in the distance apart from barrier, therefore, built-in same type is approached to the terminal of optical sensor, difference apart from barrier corresponding sampled value when two different distance is identical, it is for judging whether poor in sampled value corresponding to terminal unlimited distance away from sampled value corresponding to the critical distance of barrier and barrier of terminal that inventor introduces the first definite value.In the pre-stored memory in terminal of the first reference value.Processor approaches after the interrupting information that optical sensor reports receiving for the first time, processor can be made initialization operation to first reference value of storing in memory, compose a larger value to the first reference value, the object of composing higher value is to adjust described the first reference value, and the first reference value after the adjustment making is more approaching for judging whether that terminal is away from sampled value corresponding to the critical distance of barrier than the first reference value before adjusting.

After processor has been adjusted the first reference value, judgement gather sampled value with approach value or with away from value relation, if the sampled value of described collection is greater than the value of approaching prestoring, perform step 103, if the sampled value of described collection be less than prestore away from value, perform step 104.

103, reset describedly away from value according to the first reference value after adjusting, reset the described value of approaching according to barrier in the unlimited corresponding sampled value nearby of terminal.

Wherein, the value of approaching setting in advance described in and described in set in advance pre-stored in the register that approaches optical sensor away from value.In the time that the sampled value gathering is greater than approaching value, can illustrate that terminal approaches barrier.Terminal approaches barrier, concrete setting away from value and the method that approaching value is set can be: processor is described is set to the first reference value after adjustment away from value, because the first reference value after adjusting be more approach actual conditions terminal corresponding whether away from sampled value corresponding to the critical distance of barrier, so be whether more to approach actual conditions terminal away from sampled value corresponding to barrier away from value after arranging; The described value of approaching is set to barrier in the unlimited sampled value of correspondence nearby of terminal, because terminal approaches barrier, processor need to generate one and cut out screen message, close to make screen dimmed screen, so the described value of approaching can be set to hinder thing in the unlimited corresponding sampled value nearby of terminal so as next terminal during away from mobile phone processor can correctly control screen state, making screen is no longer closed condition.The described optical sensor that approaches judges whether that according to sampled value and away from value or with the relation that approaches value reporting interruption information is to processor.When sampled value is greater than when approaching value or sampled value and being less than away from value, approach optical sensor reporting interruption information to processor, so that processor is controlled screen state according to interrupting information after receiving described interrupting information.In the time that processor is received described interrupting information, processor can obtain and approach the sampled value of storing in optical sensor, approach value and away from value.

104, reset describedly away from value in sampled value corresponding to terminal unlimited distance according to barrier, reset the described value of approaching according to the first reference value after pre-stored the second definite value and described adjustment.

Wherein, in the time that the sampled value gathering is less than away from value, can illustrate that terminal is away from barrier.Because terminal is away from barrier, processor need to generate one and open screen message, by screen opening so that screen is brightened, so processor can describedly be set to barrier in sampled value corresponding to terminal unlimited distance away from value, so that processor can correctly be controlled screen state when next terminal approaches mobile phone, making screen is no longer opening.The described value of approaching is set to the first reference value sum after described the second definite value and described adjustment by processor.Due to described the second definite value be for judge terminal whether approach sampled value corresponding to the critical distance of barrier with for judging whether poor away from sampled value corresponding to boundary away from the critical distance of barrier of terminal, the first reference value is to approach for judging whether that terminal is away from sampled value corresponding to the critical distance of barrier, thus the second definite value and the first reference value and can be for judging whether terminal approaches the sampled value corresponding to critical distance of barrier.

105, according to described in described value of approaching after resetting and away from value control screen state.

As shown in Figure 2, further, after solving screen friction, totally do not cause sampled value bigger than normal, cause the screen problem in closed condition always, after step 102, can also comprise:

106, judge whether terminal approaches barrier first.

Describedly reset describedly away from value according to the first reference value after described adjustment, reset the described value of approaching according to barrier in the unlimited corresponding sampled value nearby of terminal, comprising:

If 107 terminals are not to approach first barrier, resetting described according to the first reference value after pre-stored friction valve and described adjustment is the first reference value sum after described pre-stored friction valve and described adjustment away from value, and resetting the described value of approaching according to barrier in the unlimited corresponding sampled value nearby of terminal is that described barrier is in the terminal sampled value of correspondence infinitely nearby.

If 108 terminals are to approach first barrier, resetting described according to the first reference value after described adjustment is the first reference value after described adjustment away from value, and resetting the described value of approaching according to the first reference value after described adjustment and described friction valve is the first reference value and the described friction valve sum after described adjustment.

105-106 is corresponding with step, after step 102, can also comprise:

109, judge that whether terminal is first away from barrier.

Describedly reset describedly away from value in sampled value corresponding to terminal unlimited distance according to barrier, reset the described value of approaching according to the first reference value after pre-stored the second definite value and described adjustment, comprising:

If 110 terminals are not first away from barrier, according to barrier sampled value corresponding to terminal unlimited distance reset described away from value for barrier is in sampled value corresponding to unlimited distance, resetting the described value of approaching according to the first reference value after described pre-stored the second definite value and described adjustment is the first reference value sum after described the second pre-stored definite value and adjustment.

If 111 terminals are first away from barrier, reset described away from value according to the first reference value after described adjustment and the 3rd pre-stored definite value, reset the first reference value after adjusting described in the described value of approaching initialization according to the first reference value after described adjustment and pre-stored friction valve, wherein, described the 3rd definite value is to be greater than 0 and be less than the constant of friction valve.

The method of the control screen state that the embodiment of the present invention provides, approach by obtaining the sampled value gathering in optical sensor, according to the first pre-stored definite value and described sampled value, the first pre-stored reference value is adjusted into more approaching for judging whether that terminal is away from sampled value corresponding to the critical distance of barrier, described the first definite value is for judging whether poor in sampled value corresponding to terminal unlimited distance away from sampled value corresponding to the critical distance of barrier and barrier of terminal, for sampled value and the value of approaching prestoring or the different relations away from value that prestore, according to the first reference value, barrier is in sampled value corresponding to terminal unlimited distance, the second definite value, barrier is in the approaching value of sampled value adjustment of the unlimited correspondence nearby of terminal and away from value, control screen state according to the described value of approaching after described resetting with away from value, with prior art by approaching compared with the method that optical sensor sets in advance a pair of identical fixed threshold and sampled value control mobile phone screen state same model, same model approached to optical sensor approaches the sampled value of optical sensor according to actual conditions and mobile phone screen state is adjusted threshold value, can ensure according to the correctness of sampled value and a pair of adjustable threshold value control mobile phone screen state.

Embodiment bis-

The embodiment of the present invention provides a kind of method of controlling screen state, is applied to the built-in terminal that approaches optical sensor 450 as shown in Figure 3, and described terminal is with screen and comprise memory 420 and processor 480.Approach and in optical sensor, have infrared light emission secondary light, light-receiving device, analog to digital converter and register.Infrared light-emitting diode periodically outwards transmitting infrared light and by the object near terminal screen by the light-receiving device in infrared light reflection light echo transducer, light-receiving device will receive after the infrared light being reflected back, generation current, and the current conversion of generation is become to voltage, the infrared light intensity size that what the size of electric current received with light-receiving device be reflected back is relevant, intensity is larger, generation current is larger, therefore voltage is also larger, by analog to digital converter, magnitude of voltage is converted into sampled value and is stored in register.Described sampled value and terminal screen are corresponding to the distance between barrier.Terminal screen is far away to the distance between barrier, and described sampled value is less, and terminal screen is nearer to the distance between barrier, and described sampled value is larger.In the register approaching in optical sensor, also store the value of approaching that sets in advance and away from value.Described is the lower limit of terminal during away from barrier away from value, and the described value of approaching is the higher limit of terminal while approaching barrier.Describedly approach register built-in in optical sensor and also stored described value of approaching and described away from value.The described optical sensor that approaches judges whether that according to sampled value and away from value or with the relation that approaches value reporting interruption information is to processor.When sampled value is greater than when approaching value or sampled value and being less than away from value, approach optical sensor reporting interruption information to processor, so that processor is controlled screen state according to interrupting information after receiving described interrupting information.Processor is in the process of screen state being controlled according to interrupting information, and other pre-stored values that need are all stored in the memory in terminal.

As shown in Figure 4, a kind of method of controlling screen state that the embodiment of the present invention provides, comprising:

201, obtain and approach the sampled value that optical sensor gathers.

Wherein, described acquisition methods, with described in step 101 in embodiment mono-, repeats no more herein.

202, judge whether the sampled value of described collection and the first definite value sum are less than the first reference value before adjustment.If the sampled value of described collection and the first definite value sum are less than the first reference value before adjustment, perform step 203; If the sampled value of described collection and the first definite value sum are more than or equal to the first reference value before adjustment, perform step 204.

Wherein, described the first definite value is that the first reference value is to approach for judging whether that terminal is away from sampled value corresponding to the critical distance of barrier for judging whether poor in sampled value corresponding to terminal unlimited distance away from sampled value corresponding to the critical distance of barrier and barrier of terminal.When sampled value and the first definite value sum of described collection are less than the first reference value, the sampled value that described collection can be described not is a very large value, can adjust the first reference value and make the first reference value after adjustment more approaching for judging whether that terminal is away from sampled value corresponding to the critical distance of barrier.When sampled value and the first definite value sum of described collection are not less than the first reference value, the sampled value that described collection can be described is a very large value, if adjust the first reference value, can make the first reference value after adjusting become a larger value and not be suitable for judging whether that terminal is away from sampled value corresponding to the critical distance of barrier.

It should be noted that, described the first reference value is stored in the memory in terminal, when the every adjustment of processor is once after described the first reference value, first reference value of storing in memory just becomes the first reference value after adjustment, and the first reference value before adjustment is capped.

203, adjusting described the first reference value is described sampled value and described the first definite value sum.

204, do not adjust described the first reference value.

205, the sampled value that judges described collection with approach value or with relation away from value.Approach value if the sampled value of described collection is greater than, perform step 206; If the sampled value of described collection is less than away from value, perform step 209.

Wherein, approaching value for for judging that terminal approaches the value of barrier, is for judging the value of terminal away from barrier away from value.For example, in the time that the distance of terminal and barrier is more than or equal to 6 centimetres, can think that terminal is away from barrier, can be sampled values corresponding to 6 centimeters away from value, in the time that the distance of terminal and barrier is less than or equal to 2 centimetres, can think that terminal approaches barrier, the value of approaching can be values corresponding to 2 centimeters.In the time that the sampled value of described collection is greater than approaching value or is less than away from value, processor need to be adjusted described value of approaching and described away from value, so that again according to the value of approaching and away from value and the correct control terminal screen state of current terminal screen state.

It should be noted that, in the described value of approaching and the register away from the pre-stored transducer in terminal of value, and described value of approaching and be adjustable away from value, every adjustment complete once approach value or away from value after, corresponding value of approaching of storing in the register of transducer or will become the value of approaching after adjustment away from value, after adjusting, using and approach value, is the value of approaching after adjusting.The sampled value that judgement gathers with approach the value of approaching used in value or the relation away from value and be the value of approaching after adjusting last time and away from value away from value, the value of approaching of adjusting each time and away from value be for judgement gathers next time next time sampled value and approaching value are provided or when away from being related to of value needs the value of approaching and away from value.

206, judge whether that terminal approaches barrier first.If terminal is not to approach first barrier, execution step 207; If terminal is to approach first barrier, execution step 208.
