Description
Technical field
The present invention relates to display screen technology field, more particularly, to a kind of red blue light filter method of display screen.
Background technology
Blue light is the important component of visible ray, and nature mixes without single white light, blue light with green glow, feux rouges in itself
White light is showed after conjunction.Green glow is smaller with Red energies, smaller to eye irritation, and blue light ripple is short, and energy is high, can be directed through
The through eye macular area of crystalline lens, causes ARM, although the harm of feux rouges is so big without blue light, can not also despise,
Often see that bright-coloured feux rouges can accelerate the fatigue of eyes, see easily causing myopia for a long time.In natural light spectrum, green glow is to eyes
Minimum light is injured, three primary light source, that is, three kinds of light of red, green, blue are used in computer, mobile phone, light fixture, to be protected
Eyes maintain green intensity it is necessary to limit the intensity of feux rouges and blue light.
At present there is following defect in product on the market：1st, anti-blue light pad pasting：Anti-blue light, not anti-feux rouges；Need once
Property investment, when not needing anti-blue light, than if desired for checking photo realistic colour with regard to helpless when taking pictures；2nd, anti-blue light eye
Eyeball：Anti-blue light, not anti-feux rouges；One-time investment is needed, the benefit than pad pasting is to remove at any time；Shortcoming is worn to not liking
The people of glasses is invalid；3rd, anti-blue light software：Anti-blue light, not anti-feux rouges；And screen intensity can be made dimmed.
Therefore, it is necessary to a kind of new technical scheme is provided to overcome drawbacks described above.
The content of the invention
Can effectively solve the red blue light mistake of the display screen of above-mentioned technical problem it is an object of the invention to provide a kind of
Filtering method.
To reach the purpose of the present invention, adopt the following technical scheme that：
A kind of red blue light filter method of display screen, is related to video card and display screen, the display screen it is red
Blue light filter method is specific as follows：First, a virtual suspended window, the virtual suspension are set by video card in display screen
Window is located at the top that display screen is shown, the virtual suspended window can be pointed to it by the Alpha colour mixture functions of video card
The red blue light of the APP user interfaces of lower section is filtered；Secondly, it is feux rouges R, green glow G, blue light through the light of virtual suspended window
B, by R=0, B=0 of the virtual suspended window of Alpha colour mixture function settings of video card, concurrently set the G=of virtual suspended window
128。
The video card is connected with display screen.
Compared with prior art, the present invention has the advantages that：The red blue light filtering side of display screen of the present invention
Method is due to cheap using pure software scheme, cost；And due to being realized using software, this method can filter red, blue light respectively, and
And the degree of controllable filtering；Simultaneously on the basis of brightness is maintained, make brightness softer, will not be excessively dark because of screen, excessively bright right
Eyes damage；It is easy to use, realized with software, start, configure it is convenient and simple.
Brief description of the drawings
Fig. 1 is the schematic diagram of the red blue light filter method of display screen of the present invention.
Embodiment
Clearly complete explanation is made to the red blue light filter method of display screen of the present invention below in conjunction with accompanying drawing.
The red blue light filter method of display screen of the present invention includes display screen and the video card being connected with display screen.
The display screen is display screen common on the market, and it can be the equipment such as mobile phone, tablet personal computer, computer
Display screen.The video card is connected with display screen, and the video card is display card common on the market, and it is prior art.
As shown in figure 1, the red blue light filter method of the display screen of the present invention is as follows：Shown first by video card
One virtual suspended window 1 is set in screen, and the virtual suspended window 1 is located at the top that display screen is shown, described virtual outstanding
The red blue light that floating window 1 can be pointed to APP user interfaces 2 below by the Alpha colour mixture functions of video card is filtered；Its
Secondary, the light through virtual suspended window 1 is feux rouges R, green glow G, blue light B, is virtually hanged by the Alpha colour mixtures function setting of video card
R=0, B=0 of floating window 1, concurrently set the G=128 of virtual suspended window 1.
Virtual suspended window 1 uses Alpha colour mixture functions, as itself R=0 and B=0, in the APP user with being disposed below
When interface 2 is superimposed, the R of display interface 3 is original half after superposition, and B is existing half, so as to right
Feux rouges and blue light are filtered, and can filter 50% original feux rouges and blue light, and the present invention can also be virtual by setting
The different R and B values of suspended window 1 are to reach the different degree filtered to feux rouges and blue light.
In the luminescent system based on three primary colours, green glow is maximum to brightness contribution, and its formula is as follows：Y=0.30R+0.69G
+ 0.11B, Y therein are brightness, and R, G, B are feux rouges, green glow and blue light respectively, and G coefficient is 0.69, and what it is than deputy R is
Count more more than one times, it is seen that contribution of the green glow to brightness is maximum, and therefore, G is as the key for maintaining brightness, it is impossible to is virtually suspended
Window 1 is filtered, and therefore, the G of virtual suspended window 1 is set as 128 by video card, so and the APP positioned at the virtual lower section of suspended window 1
The green glow that the virtual lower section of suspended window 1 is pointed to after the green glow superposed average of user interface 2 changes minimum, it is assumed that is suspended positioned at virtual
The green glow of the APP user interfaces 2 of the lower section of window 1 is G1, and the green glow after superposition is G2, then G2=(G1+128)/2, is less than for G
128 APP user interfaces, through with that can be brightened slightly after the virtual colour mixture of suspended window 1 a bit, 128 APP users circle are more than for G
It face, can become smaller slightly after colour mixture, as a result once filter equivalent to having been done to G, so that brightness is softer.
Beneficial effects of the present invention are：
1st, the alpha colour mixture functions of using realize mobile phone, the red of (flat board) computer display screen curtain, blue light filtering, do not consume
CPU, mobile phone, (flat board) computer system speed are not interfered with.
2nd, red, blue light is concurrently or separately filtered.
3rd, intensity of brightness is maintained, and makes brightness softer.
