3rd embodiment
Above-described embodiment in order to better understand the present invention, below with the light of the membrane keyboard (i.e. Touch control key) to mobile phone
The scheme being adjusted is described in detail above-mentioned technical proposal of the invention.
In the present embodiment, mobile phone touches key range and posts photoelectric conversion film, is a kind of photoelectric sensor, and the present invention is real
The luminance signal of left and right membrane keyboard can be tested by photoelectric conversion film by applying example, and automatically (including press left and right membrane keyboard
Key lamp) luminance signal be converted into electric signal, wherein there are corresponding functional relations with electric signal for optical signal.
Moreover, photoelectric conversion film is connect with mobile phone by data line in the present embodiment, the available photoelectric conversion of mobile phone
The electric signal that film transfer comes.Since brightness values signal and electric signal have functional relation, in general, brightness values are got over
The electric signal of height, conversion is stronger.After mobile phone receives electric signal, electric signal can be handled, by functional relation by telecommunications
Number it is converted into brightness number.For example, left membrane keyboard brightness number is 0.07cd/m2, right membrane keyboard brightness number is 0.21cd/
m2。
Wherein, the supply current numerical value of general press key lamp is 1 milliampere to 5 milliamperes, correspondingly, the brightness number model of membrane keyboard
Enclosing is 0.05cd/m2 to 0.25cd/m2.Preferably, the supply current generally used is 2 milliampere or so, corresponding brightness number
In 0.10cd/m2 numerical value or so.
If that identical two membrane keyboards of supply current, wherein if the brightness number of a membrane keyboard reaches another
2 times of an outer membrane keyboard brightness number, the two membrane keyboard brightness are non-uniform from the appearance in this way.If reaching 4 times
More than, it is just very uneven from the appearance, it is very ugly, need correcting current numerical value to guarantee that brightness number is close.In the present embodiment
In, if the multiple between brightness number between each Touch control key is greater than 1.5 times, be taken as non-uniform light, need into
Row current regulation.
And in the present embodiment, calculated difference value are as follows: the right membrane keyboard brightness of mobile phone is 3 times of left membrane keyboard brightness
Or left membrane keyboard brightness is the 1/3 of right membrane keyboard brightness, is taken subject to this 3 times, and this 3 times are greater than 1.5 times, then mobile phone can
The supply current of left and right membrane keyboard to be adjusted according to the luminance difference value of left and right membrane keyboard, make they after adjusting
Difference value between brightness number is less than 1.5 times.
Wherein, in the present embodiment, the numerical value of initial supply current can be set automatically by the Android system of mobile phone
It sets or adjusts.
And due to brightness regulation when the supply current to left and right Touch control key is adjusted, then it can be according to following
Electric current gear and the corresponding relationship of size of current are adjusted: in the corresponding relationship, such as every 0.125 milliampere of shelves
Position, electric current gear is since 0.Such as software setting membrane keyboard electric current gear is 6, then the size of current of membrane keyboard is by expression
0.8 milliampere or so, specifically, if software setting electric current gear be 6, the supply current calculated be 0.125* (6+1)=
0.875 milliampere；It is 15 that membrane keyboard current values, which are arranged, in software, then it represents that membrane keyboard size of current is 2.0 milliamperes, specifically, such as
It is 15 that numerical value, which is arranged, in fruit software, then the supply current calculated is 0.125* (15+1)=2.0 milliampere.
It is noted, of course, that as the magnitude of current differed between each gear, can according to practical application scene into
Row flexible setting, such as hereinafter, with every 0.25 milliampere of gear come pair that is arranged between electric current gear and size of current
It should be related to, i.e., the magnitude of current of the invention for differing between each gear is simultaneously not specifically limited.
Wherein, mobile phone the corresponding relationship according to above-mentioned electric current gear and size of current come be adjusted by software come
When adjusting the supply current of left and right membrane keyboard, in order to make the difference value between their brightness number after adjusting less than 1.5 times.
For example, the initial supply current of left and right membrane keyboard is 2.5 milliamperes, and the brightness number of obtained left membrane keyboard is 0.07cd/
M2, right membrane keyboard brightness number are 0.21cd/m2.It is evident that needing to improve the supply current of left membrane keyboard, to right touch
The supply current of key reduces, wherein can directly determine the electric current tune to left and right membrane keyboard according to the multiple (3 times) of the difference
Section amount, it can directly increase or decrease the electric current gear of left and right membrane keyboard to the brightness number that can correspondingly make between them
Electric current gear of the difference value of value within 1.5 times.It can also carry out multiple gear respectively to adjust, to make after adjusting electric current
The difference value of the brightness number of left and right membrane keyboard is within 1.5 times.
Wherein, the current regulation of one-time-reach-place can save the current regulation time, accelerate the brightness regulation speed of light, but
It is due to differing certain current values (0.25 milliampere as escribed above) between each gear, so the accuracy adjusted is opposite
It is lower with accuracy repeatedly in place；And repeatedly current regulation in place then can more accurately realize brightness regulation.
The regulation scheme to electric current is described in detail by taking current regulation scheme repeatedly in place as an example below:
Here, it needs to improve a class to the supply current of left membrane keyboard, correspondingly, software can select a current gear
Bit value, so that control becomes 2.75 milliamperes from 2.5 milliamperes to the supply current numerical value of left membrane keyboard, the confession of right membrane keyboard electric current
Electric current can reduce a class, and current values become 2.25 milliamperes from 2.5 milliamperes.
After adjusting electric current, photoelectric conversion film detects the luminance signal of left and right membrane keyboard automatically again, and left and right is touched
The luminance signal of key is converted into electric signal and is sent to mobile phone, and mobile phone carries out conversion process to electric signal again, obtains updated bright
Degree value.If the difference between the updated brightness number of left and right membrane keyboard still at 1.5 times or more, continues to repeat above-mentioned
The adjusting of supply current operates.It circuits sequentially, until the brightness number difference of left and right membrane keyboard narrows down within 1.5 times.
Finally, the brightness number difference when left and right membrane keyboard narrows down within 1.5 times, the brightness of left and right membrane keyboard is indicated
Value is qualified, the gamma correction success of mobile phone membrane keyboard.
Certainly, the present invention above-mentioned specific example is only illustrated by taking the light of left and right membrane keyboard as an example, but
In other embodiments, the light-emitting component adjusted to light is not limited to two membrane keyboards, can be extra 1 any number of
Membrane keyboard；Meanwhile being also not limited to carry out brightness regulation to the light of membrane keyboard, it can also be to the red of the breath light on mobile phone
Luminance difference between lamp and green light is adjusted.
The embodiment of the present invention pastes a photoelectric conversion film by the touch key range of the mobile phone in membrane keyboard brightness irregularities,
Photoelectric conversion film can be converted into the variation of luminous intensity the variation of electric signal.Photoelectric conversion film is by the optical brightness of membrane keyboard
Signal is converted into electric signal, and electric signal is returned to mobile phone by data line and is handled, and electric signal is then converted to by mobile phone
Brightness number.Mobile phone carries out the current regulation of press key lamp according to luminance difference automatic start up system software, and until left and right, touch-control is pressed
The luminance difference of key is in scope of design.
Touch controlled key is done circuit design by the present invention respectively, so as to automatically adjust press key lamp electricity by cell phone system software
Flow size, to control the luminance difference of left and right touch controlled key, until touch controlled key luminance difference permission scope of design
It is interior.Operation of the present invention is simple, and time-consuming is short, without a large amount of artificial full inspection and quality sampling observation, without the mold design for doing complexity
It is assembled with jig, greatly reduces cost of labor and assembly detection difficulty, high reliablity improves the consistent of complete machine appearance
