Detailed Description
In order to make the technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
An embodiment of the present invention provides an eye protection method for a display device, where fig. 1 shows a light path diagram of the display device in this embodiment, and before describing the eye protection method in this embodiment, first, the display device in this embodiment is described in detail:
in fig. 1, the display device includes a backlight and a display panel disposed on a light emitting side of the backlight.
Most of display products in the current market adopt a backlight mode of a white light LED light source, and the peak wavelength of the white light LED light source is about 450nm, so that visual fatigue can be caused when the display products are watched for a long time.
Therefore, in the present embodiment, a backlight source as shown in fig. 1 is adopted, in fig. 1, the backlight source in the present embodiment includes a blue LED light source 300 and a quantum dot film 400 disposed along a light path of the blue LED light source 300, and blue light emitted by the blue LED light source 300 is mixed by the quantum dot film 400 to form white light.
Specifically, in fig. 1, the backlight source further includes a rear case 100, and a reflective film 200 formed on the rear case 100, the plurality of blue LED light sources 300 are arranged in an array manner, and a diffusion plate, a quantum dot film 400, a first prism film 500, a second prism film 600, and a display panel 700 are sequentially disposed on a light path of the blue LED light sources 300.
It should be noted that, in this embodiment, the quantum dot film 400 should be understood as a film material including a plurality of quantum dot particles, and since the blue light emitted by the blue LED light source 300 is mixed by the quantum dot film 400 to form white light, the quantum dot film 400 is mixed with red quantum dot particles and green quantum dot particles, where the quantum dot film 400 can effectively improve the color saturation and the color gamut of the display device, fig. 2 shows a spectrum diagram of the backlight source in fig. 1, and it can be seen from the diagram that, with the backlight source shown in fig. 1, after the blue light emitted by the blue LED light source 300 is emitted by the quantum dot film 400 and mixed into white light, the energies of the three RGB colors are balanced, the energy of the color connection band is high, and thus the color purity is high.
The eye protection method in this embodiment is described in detail below with reference to the display device shown in fig. 1, where fig. 3 shows a flowchart of the eye protection method of the display device in this embodiment, and the eye protection method includes the following steps:
s100, acquiring a spectrum of the white light;
specifically, in S100, a spectrum detector may be used to detect white light, so as to generate a spectrum corresponding to the white light, where the white light is a mixed light, and therefore, includes lights with different wavelengths, and thus, the spectral values of the white lights with different wavelengths are also different, and for example, table 1 shows the spectral values of the white light with a wavelength of 380 nm:
TABLE 1
S200, obtaining a spectrum of RGB light formed by the white light through a color film substrate;
specifically, similarly to S100, in S200, a spectrum detector may also be used to detect the RGB light formed by the white light via the color film substrate, so as to generate a spectrum of the corresponding RGB light, and since the RGB light includes light with different wavelengths, the spectral values of the RGB light with different wavelengths are different, and for example, table 2 shows the spectral values of the RGB light with a wavelength of 380 nm;
TABLE 2
S300, fitting the spectrum of the RGB light formed by the color film substrate and the spectrum of the light emitted by the backlight source based on the CIE1931 spectrum tristimulus values to obtain the tristimulus values of the RGB light under different wavelengths;
it should be noted that, according to the three primary color principle, a color image can be decomposed into three primary color images, the color information displayed by the LED backlight television is mainly a color image (RGB light) generated by white light emitted from a backlight source via a color film substrate, the color measurement principle, the basic data and the calculation method specified by the international commission on illumination (CIE) are called as CIE standard colorimetry system, and according to the tristimulus value formula of the light source color and the object color, a color tristimulus value expression of the system can be obtained:
wherein,
it is the tristimulus value of the spectrum of a CIE1931 standard chromaticity observer;
here, the CIE 1931-XYZ system selects X, Y, Z as the three primary colors, the three primary colors are used for matching the isoenergetic spectral colors, the spectral tristimulus values of the system are standardized and are named as "CIE 1931 standard chromaticity observer spectral tristimulus values", which is called as "CIE 1931 standard chromaticity observer" for short.
Therefore, in S300, the spectrum of the RGB light formed by the color film substrate and the spectrum of the white light may be fitted based on the CIE1931 spectrum tristimulus values to obtain tristimulus values of the RGB light at different wavelengths;
wherein, in one implementation, S300 further includes the following sub-steps:
s310, multiplying an X value in the CIE1931 spectrum tristimulus value under the same wavelength by a spectrum value of the white light, and multiplying a product result by an R value, a G value and a B value in the spectrum of the RGB light corresponding to the wavelength respectively to obtain an X value, a Y value and a Z value in the R values of the RGB light tristimulus values under different wavelengths respectively;
s320, multiplying a Y value in the CIE1931 spectrum tristimulus values under the same wavelength by a spectrum value of the white light, and multiplying a multiplication result by an R value, a G value and a B value in the spectrum of the RGB light corresponding to the wavelength respectively to obtain an X value, a Y value and a Z value in the G values of the RGB light tristimulus values under different wavelengths respectively;
s330, multiplying the Z value in the CIE1931 spectrum tristimulus value with the spectrum value of the white light under the same wavelength, and multiplying the multiplication result with the R value, the G value and the B value in the spectrum of the RGB light corresponding to the wavelength respectively to obtain the X value, the Y value and the Z value in the B values of the RGB light tristimulus values under different wavelengths respectively.
Specifically, the method for calculating the tristimulus values of RGB light at different wavelengths is as follows: firstly, knowing a CIE1931 spectrum tristimulus value, a spectrum of white light obtained in S100 and S200, and a spectrum of RGB light formed by the white light through a color filter substrate, for example, table 3 shows the CIE1931 spectrum tristimulus value with a wavelength of 380 nm;
TABLE 3
Then, at the same wavelength, for example: 380nm, multiplying an X value in a CIE1931 spectrum tristimulus value under a corresponding wavelength by a spectrum value of white light, then multiplying a multiplication result by an R value, a G value and a B value in a spectrum of RGB light, so as to obtain an X value, a Y value and a Z value in the R value of a tristimulus value of the RGB light under 380nm, similarly, obtaining the G value and the B value of the tristimulus value of the RGB light under 380nm by using the same method, so as to obtain the tristimulus value of the RGB light under 380nm, and finally obtaining the tristimulus values of the RGB light under other different wavelengths in sequence, wherein, for example, table 4 shows the tristimulus values of the RGB light under 380 nm:
TABLE 4
S400, obtaining a spectrum of light emitted by the display device based on the three primary color values of the RGB light under different wavelengths;
specifically, in S300, the tristimulus values of RGB light at different wavelengths can be obtained, and thus in S400, the spectrum of light emitted by the display device can be further obtained from the tristimulus values of RGB light at different wavelengths.
Wherein, in one implementation, the S400 further includes the following sub-steps:
s401, summing R values, G values and Y values in B values of RGB light under different wavelengths to obtain a summation result;
s402, dividing the summation result by a Y value in the CIE1931 spectrum tristimulus values corresponding to the wavelengths to obtain a spectrum value of the light emitted by the display device corresponding to the wavelengths;
and S403, obtaining the spectrum of the light emitted by the display device based on the spectrum values of the light emitted by the display device under different wavelengths.
Specifically, first, at the same wavelength, for example: 380nm, summing the R value, the G value and the Y value in the B value of the RGB light under 380nm wavelength to obtain a summation result, further, dividing the summation result by the Y value in the CIE1931 spectrum tristimulus value under 380nm wavelength to obtain the spectrum value of the light emitted by the display device under 380nm wavelength, and finally sequentially obtaining the spectrum values of the light emitted by the display devices under other different wavelengths to obtain the spectrum of the light emitted by the display device.
S500, judging whether the peak wavelength of blue light in the spectrum of the light emitted by the display device is in a preset range;
specifically, whether the wavelength of the peak of the blue light in the spectrum is within the preset range is checked according to the spectrum of the light emitted by the display device obtained in S400, wherein the short-wave blue light with the wavelength within 415-450nm can increase the amount of toxins in the macular region in the eye, so the preset range can be set to be between 415-455nm, and when the peak wavelength of the blue light in the spectrum of the light emitted by the display device is within 415-450nm, it can be determined that the light emitted by the display device is irradiated on the human eye for a long time, which can seriously threaten the health of the fundus oculi, and therefore, the display device needs to be adjusted.
And S600, adjusting the display device according to the judgment result.
When the peak wavelength of the blue light in the spectrum of the light emitted by the display device is within a preset range, the display device is adjusted, so that the peak wavelength of the blue light in the spectrum of the light emitted by the display device is not within the preset range, the blue light wave band is avoided, and the purpose of protecting eyes is achieved.
Here, the adjustment method mainly includes the following three schemes:
the first method comprises the following steps: the wavelength of the blue light emitted by the blue LED light source 300 is increased or decreased, and here, the specification of the blue LED light source 300 is changed to increase or decrease the wavelength of the blue light emitted by the blue LED light source 300, so that the peak wavelength of the blue light in the spectrum of the light emitted by the display device is further not in the preset range.
And the second method comprises the following steps: the diameter of the quantum dot particles in the quantum dot film 400 is increased or decreased, and the size of the quantum dot particles determines the wavelength band of light generated after the blue LED light source 300 is excited, as known from the material characteristics of the quantum dot particles, according to the adjustment of the size of the quantum dot particles, the blue light emitted from the blue LED light source 300 can generate white light mixed with blue, green, red, etc. colors after passing through the quantum dot film 400, and by increasing the diameter of the quantum dot particles, the peak wavelength of the blue light emitted by the blue light LED light source 300 after passing through the quantum dot film 400 can be increased, and correspondingly, the peak wavelength of the blue light emitted by the blue light LED light source 300 after passing through the quantum dot film 400 can be decreased by decreasing the diameter of the quantum dot particles, thereby further causing the peak wavelength of blue light in the spectrum of light emitted by the display device to be outside the predetermined range.
Third, the wavelength of the blue light emitted by the blue LED light source 300 is increased or decreased; and increasing or decreasing the diameter of the quantum dot example in the quantum dot film 400, in a third scheme, the former two schemes may be combined, and the diameter of the quantum dot particles in the quantum dot film 400 and the wavelength of the blue light emitted by the blue LED light source 300 are changed, so as to further make the peak wavelength of the blue light in the spectrum of the light emitted by the display device not in the preset range.
