Description
[technical field]
The present invention relates to LED screen display field, a kind of regulate the method that LED screen blue light shows.
[background technology]
Popularizing of the smart machine such as computer, mobile phone, brings unprecedented test to eyes, and human eye sees computer, mobile phone for a long time,
The pipeline that LED screen distributes can be different from difference to the biological clock of the stimulus effects human eye of human eye, the light distributed due to LED screen
Natural light, between screen light and natural light, delicate difference even can allow human body is uncomfortable, produce sleeping problems, and scientist finds indigo plant
Light content, spectral distribution can affect human eye perception, and by the way of software, screen light can be adjusted so as to more conform to health
Rule.
[summary of the invention]
The present invention provides a kind of regulation LED screen blue light controlling blue content by the way of software processes to show
Method.
For solving the problems referred to above, the present invention adopts the following technical scheme that
The method that regulation LED screen blue light shows, it comprises the steps:
Step 1, according to sunrise and sunset time, calculate the filtering degree to blue light, use following algorithm:
00:00+offset2-03:00+offset1, filtering degree increases according to the time and changes from 100%-90% equal proportion；
03:00+offset1-07:00+offset1, filtering degree increases according to the time and changes from 90%-40% equal proportion；
07:00+offset1-12:00+offset2, filtering degree increases according to the time and changes from 40%-20% equal proportion；
12:00+offset2-18:00+offset2, filtering degree increases according to the time and changes from 20%-40% equal proportion；
18:00+offset2-24:00+offset2, filtering degree increases according to the time and changes from 40%-100% equal proportion；
Wherein, Offset1 is current sunrise time-6:00
Wherein, Offset2 is current sunset time-18:00；
Software is installed in computer or mobile phone, by presetting or calling computer, the position of mobile phone and date and time,
Or confirm computer or the use position of mobile phone and current date and time by transferring GPS software, and then obtain this position
The sunrise time put and sunset time, obtain the filtering degree of the needs of blue light by the algorithm in step 1.
Blue light helped and refreshed oneself daytime, blue light impact sleep at night.The most just best suit human body rule light, natural
Light is followed sunset sunrise and is presented by secretly to bright, then by the bright dimmed natural rhythm and pace of moving things.Screen also should be followed for the filtration of blue light
This rule is the most healthy, and such as high noon, 12 filter value should be more on the low side, should be larger to filter value at night.So
There is a following algorithm:
00:00-03:00, filtering degree increased from 100% to 90% equal proportion change according to the time；
03:00-07:00, filtering degree increases the time from the change of 90%-40% equal proportion according to the time；
07:00-12:00, filtering degree increases according to the time and changes from 40%-20% equal proportion；
12:00-18:00, filtering degree increases according to the time and changes from 20%-40% equal proportion；
18:00-24:00, filtering degree increases according to the time and changes from 40%-100% equal proportion.
Various Seasonal nature light rule over time is different, divides rule approximately by sunset sunrise time
Rule, algorithm above is to process filtering degree with the light Changing Pattern of sunset time 6:00, sunrise time 18:00.For reality
Situation, also should do translation according to sunset sunrise time and process, so final algorithm is:
00:00+offset2-03:00+offset1, filtering degree increases according to the time and changes from 100%-90% equal proportion；
03:00+offset1-07:00+offset1, filtering degree increases according to the time and changes from 90%-40% equal proportion；
07:00+offset1-12:00+offset2, filtering degree increases according to the time and changes from 40%-20% equal proportion；
12:00+offset2-18:00+offset2, filtering degree increases according to the time and changes from 20%-40% equal proportion；
18:00+offset2-24:00+offset2, filtering degree increases according to the time and changes from 40%-100% equal proportion；
Wherein, Offset1 is current sunrise time-6:00
Wherein, Offset2 is current sunset time-18:00；
Described equal proportion is changed to increase over time, and the changing value in filtering degree interval carries out decile, temporally
Increase number, improve or reduce filtering degree preset share.
Step 2, the filtering degree to blue light calculated from step 1, calculate the input value of blue light in LED screen
InputB, uses following function:
The filtering degree of the blue light calculated during wherein n is step 1.
Its principle is by controlling the color filtration degree that RGB input establishment is from 0% to 100%.The most each number of degrees
Ratio is inputted for fixing RGB.
Assume that each input of RGB is InputR (red), InputG (green), InputB (blue), then 0% filtering degree is corresponding
It is 100%InputR, 100%InputG, 100%InputB；When filtering degree is 100%, that corresponding is 90%InputR,
75%InputG, 50%InputB.
Filtering degree is from 0% to 100% change.RGB tri-input excursion then:
R:100%-90%G:100%-75%B:100%-50%
Above InputR and InputG only has more small excursion, allows them present linearly change along with color filtration degree
Changing, and the excursion of InputB is relatively large, the linear change of InputB can not allow user feel filter effect
It is that nature changes uniformly.
Above Input is physical quantity accurately, but human body includes the perception to physical quantity variation such as audition, vision
Linear variability law can not be met.Inside music system, each sound can carry out accurate description by frequency, however each note from
Bass is not linearly to change to the frequency of high pitch.It is according to twelve-tone equal temperament, sound on the basis of f, in interval [f, 2f]
To 13 different single-tones, their frequency is respectively as follows:
What therefore they were constituted is an exponential curve, and the frequency of the n-th sound is that f is multiplied by
In order to meet human eye sense organ, allow filter effect present nature and change uniformly, we allow InputB with filtering degree in
Exponential function changes, and variation relation is as follows:
When filtering degree is n%,
And allow the filtering degree to blue light meet above-mentioned function, in the way of facilitating by software, calculate in different situations
The input value of the blue light of lower correspondence
Wherein, blue light filtering degree is from 0% to 100%, and the numerical range of corresponding blue light input value InputB is 100%-
50%.
Wherein, sunrise time is 6:00, and sunset time is that the blue light filtering degree of 18:00 is:
00:00-03:00, filtering degree increased from 100% to 90% equal proportion change according to the time；
03:00-07:00, filtering degree increases the time from the change of 90%-40% equal proportion according to the time；
07:00-12:00, filtering degree increases according to the time and changes from 40%-20% equal proportion；
12:00-18:00, filtering degree increases according to the time and changes from 20%-40% equal proportion；
18:00-24:00, filtering degree increases according to the time and changes from 40%-100% equal proportion.
The present invention has 1) depend on the operating system such as windows, Android, it is not necessary to machine hardware is arranged, it is not necessary to patch thing
Reason film, only need to install software in place system and both can reach to optimize effect of screen filter blue light；2) intelligence and press close to biology
The algorithm of rule offers convenience by user, eliminates the time manually regulating parameter；3) LED screen blue light is inhibited to endanger,
Protection eyes, the advantage of useful for sleeping.
