Below in conjunction with accompanying drawing, the embodiment of the present application technical scheme main realized to principle, embodiment and the beneficial effect that should be able to reach is explained in detail.
Embodiment mono-:
Please refer to Fig. 1, the embodiment of the present application provides a kind of method backlight of controlling, and comprising:
S101: gather first brightness value that includes the input equipment place environment of at least one button.
The mode of the brightness value in measurement environment is varied, the brightness value that can determine environment by the infrared ray in collection environment and ultraviolet mode in embodiments of the present invention., specifically, the implementation procedure of the first brightness value that described collection one includes the input equipment place environment of at least one button can be:
First, gather infrared ray or a ultraviolet ray that includes the input equipment place environment of at least one button;
Then, described infrared ray or described ultraviolet intensity are converted into electrical signal intensity, utilize described electrical signal intensity to identify the first brightness value of described environment.
For the first brightness value that makes to obtain more accurate, can select inside that the light sensor of high precision photoelectric pipe is housed, to photoelectric tube two ends, apply a reverse fixedly pressure, make to collect any light particularly infrared ray and ultraviolet ray, photoelectric tube will discharge electronics, when intensity of illumination is higher, the electric current of photoelectric tube is also just larger, so the electrical signal intensity that can obtain by conversion judges the light intensity of described environment.
After execution step S101, the method in the embodiment of the present application enters S102, judges that whether described the first brightness value is less than a default brightness value, obtains the first judged result that is:.
What whether the bright-dark degree that identifies input equipment place environment for the first brightness value gather obtaining can make human eye clearly observes surroundings, need to further confirm.Show that according to the study human eye generally can see thing clearly in light luminance value is the environment of 30-10000 nit, when light luminance value lower than 30 nit time sight line will fog, so, in the present embodiment, the minimum brightness value that a human eye can be able to be seen clearly to thing is preset as 30 nits, so just described the first brightness value and 30 nits can be compared, confirm that described environment is bright or dark.Suppose that it is 20 nits that step S101 collects first brightness value that includes the input equipment place environment of at least one button, judgement obtains 20 nits and is less than 30 nits so, obtain first and judgment result is that keyboard ambient brightness value is around lower than default brightness value, and when the first brightness value is 40 nit, judgement obtains 40 nits and is greater than 30 nits so, obtains first and judgment result is that keyboard ambient brightness value is around higher than default brightness value.。
The the first judged result execution step S103 obtaining according to S102: when described the first judged result shows described the first brightness value lower than described default brightness value, generate a distance and detect instruction.
In this application, not only to consider bright and dark light degree judging when whether user needs to open keyboard back light, also need to consider user's actual demand, as: whether really will use keyboard.Specifically, in two kinds of situation:
The first: show that in the first judged result described the first brightness value is lower than described default brightness value, but user does not need to use keyboard, at this time, just show to open keyboard back light.
The second, show that described the first brightness value is lower than described default brightness value, but user need to use keyboard in the first judged result, at this time, just shows it is to open keyboard back light.
In this application, when the second situation meets, will generate a distance and detect instruction, by carrying out distance, detect instruction, can judge the operating body for operation keyboard, as hand, and the distance between keyboard.
When generate a distance by step S103, detect after instruction, the method in the embodiment of the present application continues execution step S104: carry out described distance and detect instruction, detect the actual distance value obtaining between an operating body and described input equipment.
In most of the cases, because user must knock or push button when using input equipment, input equipment and user's hand and the distance of health are to exceed certain distance scope, so, by the distance value between the input equipments such as keyboard and operating body, can effectively judge user and whether maybe will use input equipment.
When detecting the actual distance value obtaining between an operating body and described input equipment, can be by the actual distance value between described operating body and described input equipment in a Proximity Sensor detection acquisition preset range.Proximity Sensor is again displacement transducer, utilize the physical change amount of various element testing objects, by this variable quantity is scaled to distance, measure the distance displacement from transducer to object, there is sensitive and accurate feature, can improve accuracy and the detection efficiency of actual distance value.
Specifically, the implementation of step S104 has:
The first: detect and take keyboard center in the upper area that 20 centimetres, the center of circle is radius by Proximity Sensor, the actual distance value of operating body and keyboard, for example Proximity Sensor probe is arranged on to notebook backlight keyboard " H " by keyway, detects and take the actual distance value of the interior hand of keyboard of notebook computer button " H " upper area that 20 centimetres is radius as the center of circle and " H ".
The second: detect in keyboard epitaxial region 30 cm range by Proximity Sensor, the actual distance value of operating body and keyboard, for example Proximity Sensor probe is arranged between computer-keyboard " Alt " key and keyboard edge, detects the actual distance value of the interior health of keyboard extension 30 cm range and keyboard extension.
Certainly, under the application, technical staff can also adopt alternate manner as required, and at this, the application has just given an example no longer one by one.
After step S104, obtain after the actual distance value of input equipment and operating body the method execution step S105 in the embodiment of the present application: judge that whether described actual distance value is less than a predeterminable range value, obtains the second judged result.
According to the difference of actual detection mode, the setting of predeterminable range value is also different.The first, detection be take keyboard center in the upper area that 20 centimetres, the center of circle is radius, during the actual distance value of operating body and keyboard, because the distance of operating body hand and keyboard can be smaller, so predeterminable range value can be made as the value closer with keyboard distance, as 5 centimetres.The second, detects in keyboard epitaxial region 30 cm range, and during the actual distance value of operating body and keyboard, the permission of the distance of health and keyboard is in the distance of proficiency brachium, so predeterminable range can be made as the value far away with keyboard extension, as 20 centimetres.
After step S105, perform step S106: when described actual distance value is less than described predeterminable range value, generate a backlight open instruction, if the second judged result shows to stop when described actual distance value is more than or equal to described predeterminable range value this operational cycle.
When having backlight open instruction to generate, S107: carry out described backlight open instruction, open at least one luminescence unit corresponding with described at least one button.
In most of the cases, at least one luminescence unit that described at least one button is corresponding can be Light-Emitting Diode, because light-emitting diode operating voltage is very low, very little being adapted at of operating current used on the low power consumption input equipments such as keyboard, shock resistance and the anti-seismic performance of light-emitting diode are good simultaneously, be applicable to the input equipment that keyboard type length is knocked, make that reliability backlight is high, the life-span is long.White luminous diode can embed design in keyboard draw-in groove, because each button of keyboard adopts special polymer black partly to have good light-proofness, white portion possesses very strong transparency, so after opening the white luminous diode of high brightness, keyboard can be good at illuminating and does not affect surrounding environment.For very convenient the user in processing transactions at night, and can not have influence on household and have a rest.
In order to judge more accurately whether user will use keyboard input really, can be before step S106 generate a backlight open instruction, repeating step S104, S105: again detect the second actual distance value obtaining between an operating body and described input equipment; Judge whether described the second actual distance value is less than the actual distance value that detects for the first time acquisition, if judged result is the second actual distance value, is less than the actual distance value detecting for the first time and shows that operating body is close to keyboard, determine that user will use keyboard really, perform step S107 and open keyboard back light.
In the embodiment of the present application, to opening at least one luminescence unit corresponding with described at least one button, can also inquire about and obtain the monochrome information corresponding with described actual distance value, based on described monochrome information, open at least one luminescence unit corresponding with described at least one button, making the luminous brightness of described luminescence unit is the brightness of described monochrome information sign.
As the actual distance value detecting is 10 centimetres and is less than 20 centimetres of predeterminable range values, it is 100 nits that now inquiry obtains 10 centimetres of corresponding monochrome informations of actual distance value, opening so keyboard back light, to make its brightness value be 100 nits, if actual distance value is 8 centimetres of brightness so backlight, can be 80 nits.By judgement human body, apart from the distance of keyboard, obtain the distance of user's sight line, when user distance keyboard is closely to less lower than predeterminable range value, by backlight, turn on, so that user can clearly identify keyboard; Nearer, but more lower than predeterminable range value when user distance keyboard, by backlight, weaken, now user also can clearly identify keyboard, to play the technique effect of power saving.
In some cases, user distance keyboard enough closely even leans against on keyboard but user does not input any content, now keyboard back light can cause the waste of resource always in opening, so the application is after opening at least one luminescence unit corresponding with described at least one button, in Preset Time section, detect described input unit and whether have input operation, obtain a testing result, if testing result is nothing, close at least one luminescence unit corresponding with described at least one button.If Preset Time is 3 minutes, in 3 minutes, user does not input any content by keyboard, and closing keyboard is backlight automatically, avoids the waste of resource.
Below in conjunction with an actual use procedure, to the method in the embodiment of the present application, specifically should be used as a detailed description:
Suppose user A just one with window but in the very dim room of whole light, use one with the notebook computer of backlight keyboard, the brightness value that the light sensor of this backlight keyboard collects keyboard place environment is 25 nits, because 25 nits are less than default brightness value 30 nits, just open distance detection function.Now user A chats by notebook computer and friend, when friend given back information " having a meal? " after, user A just need to be inputted and " also not have by keyboard in the text input field of QQ software.", when user A stretches out one's hand on keyboard, when Proximity Sensor detects in one's hands and actual range keyboard and is less than 5 centimetres of predeterminable ranges, open keyboard back light, user A " is not also had in input." time can see keyboard clearly.When having inputted, user A " also do not have." after friend all there is no reply always, user A does not also just input any content, now input detection unit detects 3 minutes internal keyboards without any input content, judges and show that keyboard is not used that closing keyboard is backlight.
After a period of time, user A has opened indoor electricity-saving lamp, and user A is just preparing to input in the text input field of QQ software by keyboard that " you are very busy, and I have descended Kazakhstan."; because user A has now opened indoor electricity-saving lamp; the brightness value that the light sensor of backlight keyboard detects keyboard periphery is that 50 nits are greater than default brightness value 30 nits; can not open distance detection function; even if now user A is near keyboard and use keyboard input " it seems that you are very busy, I have descended Kazakhstan.", keyboard back light can not opened yet, and has avoided the waste of resource.
Method in the embodiment of the present application, at least has following technique effect:
By adopting light and range sensor automatically to control opening and closing backlight, solve prior art and cannot automatically control technical problem backlight, reached the technique effect that automation is controlled; Avoided use physical button to control backlight, physical button is long easily occurs that button malfunction causes the technical problem that cannot open backlight, has improved the reliability of backlight control simultaneously.Because control backlight is completed automatically by transducer and control appliance, the use of whole electronic equipment is more intelligent simultaneously, and user experiences better.In the process of using, the application's input equipment backlight is at light enough secretly and to open input equipment user distance input equipment enough closely has input purpose in the situation that backlight, in closed condition when all the other times are backlight, there is good power saving effect.
