The light wavelength corresponding to the color to be displayed of the target light wavelength refers to the light wavelength corresponding to the color to be displayed in the display screen, and for an image to be displayed in the display screen, the position of each pixel point of the display screen corresponds to one color, namely, the light wavelength corresponds to one target light wavelength.
Referring to fig. 2, in some embodiments, at least two F-P cavities 21, include: the first and second F-P cavities 211 and 212 include only one transmission peak having the same wavelength therebetween, respectively, in a case where the thickness of the first F-P cavity 211 is a first target thickness and the thickness of the second F-P cavity 212 is a second target thickness.
The first F-P chamber 211 may also be referred to as a primary F-P chamber, and the second F-P chamber 212 may also be referred to as a secondary F-P chamber.
With continued reference to FIG. 2, the F-P chamber 21 includes: a substrate 201, a first reflective layer 202, a second reflective layer 204, and a conductive layer 205;
the first reflective layer 202 and the second reflective layer 204 are located between the substrate 201 and the conductive layer 205;
an adjusting component (not shown in the figure) is positioned between the first reflecting layer 202 and the second reflecting layer 204, the adjusting component is fixedly connected with the first reflecting layer 202 and the second reflecting layer 204 respectively, and the adjusting component is used for adjusting the distance between the first reflecting layer 202 and the second reflecting layer 204;
the adjusting component is electrically connected with the conductive layer 205, and the adjusting component is electrified through the conductive layer 205, so that the adjusting component is electrically controlled.
In this embodiment, the substrate 201 may be made of a flat glass plate, the first reflective layer 202 and the second reflective layer 204 play a role of reflecting light, a cavity 203 is formed between the first reflective layer 202 and the second reflective layer 204, the adjusting member is disposed in the cavity 203, and the thickness of the whole F-P cavity 21 is adjusted by adjusting the thickness of the cavity 203, as shown in fig. 2, a represents the thickness of the cavity 203 in the first F-P cavity 211, and a represents the thickness of the cavity 203 in the second F-P cavity 212.
Specifically, in some embodiments, the adjusting component is an electrostrictive polymer or an electro-optic effect polymer, and the electrostrictive polymer or the electro-optic effect polymer can deform when being electrically stimulated, so that the thickness, the refractive index and the like between the first reflecting layer 202 and the second reflecting layer 204 can be changed
It should be noted that the control of the deformation amount of the electrostrictive polymer or the electro-optic effect polymer mainly depends on the voltage value applied thereto, specifically, the corresponding relationship between the deformation amount and the voltage value may be obtained in advance through experiments or tests, and when the F-P thickness is actually controlled, the voltage value to be used can be determined directly according to the deformation amount that needs to be adjusted.
The working principle of the F-P cavity is described as follows:
the F-P cavity is formed according to the principle of parallel panel-to-beam interference, which is shown in fig. 3, and the reflected beams 2, 3, 4 and the transmitted beams 1 ', 2 ', 3 ' have relatively close intensities and can pass through, thereby generating the multi-beam interference phenomenon.
The spectral characteristics of the F-P cavity are shown in fig. 4 below, with several transmission peaks. Under the action of an external voltage, the thickness and the refractive index of the cavity of the electrostrictive polymer in the F-P cavity are changed, so that the wavelength of a transmission peak of the F-P cavity is shifted. Thereby achieving the purpose of tuning the wavelength.
Specifically, as shown in fig. 5, under the action of an external voltage, the cavity length and the refractive index of the medium in the cavity of the two resonant cavities of each pixel point change, so that the wavelength of the transmission peak of each FP cavity moves, and the cavity length and the refractive index of the first FP cavity and the second FP cavity can be respectively controlled by controlling the voltage, so that the wavelength of the transmission peak of the two resonant cavities moves
For example: under the action of an external voltage, the wavelengths of the transmission peaks of the two F-P cavities move (respectively, the upper diagram and the middle diagram in fig. 5), the wavelengths of the two F-P cavities are only the same in the 540nm band, the two F-P cavities are superposed, and finally only the light energy in the 540nm band penetrates (as shown in the lower diagram in fig. 5), and the rest bands cannot pass through.
The wavelength bands of light and the colors of the light have corresponding relations, the light with different wavelength bands is different colors, the backlight emits white light, the white light contains full-wavelength visible light, the white light is filtered by the F-P cavities in the pixel points to become single-wavelength light, namely single-color light, the display pixel points enable the lengths (such as A and a in figure 2) of the two cavities to change by adjusting the voltage, so that the light wavelength bands which can be penetrated are adjusted by the combined action of the first-level F-P cavity and the second-level F-P cavity, the light with the wavelength bands corresponding to the color to be displayed in the white light passes through, the light with other wavelength bands is filtered, different colors can be displayed by controlling the cavity lengths of the first-level F-P cavity and the second-level F-P cavity of each pixel point.
For example, the following steps are carried out:
when the pixel point 1 is to display red, the cavity thickness A in the primary F-P cavity of the pixel point 1 is adjusted through voltage to be A1, and the cavity thickness a in the secondary F-P cavity is adjusted to be a 1;
when the pixel point 1 is to display purple, the cavity thickness A in the primary F-P cavity of the pixel point 1 is adjusted through voltage to be A2, and the cavity thickness a in the secondary F-P cavity is adjusted to be a 2;
when the pixel point 1 needs to display cyan, the cavity thickness A in the primary F-P cavity of the pixel point 1 is adjusted through voltage to be A3, and the cavity thickness a in the secondary F-P cavity is adjusted to be a 3;
and so on, when different colors are displayed, the thickness A of the cavity in the first-stage F-P cavity and the thickness a of the cavity in the second-stage F-P cavity are adjusted, so that light with corresponding colors (wave bands) passes through, and light with other colors (wave bands) is filtered.

in the embodiment of the present application, the resonant cavity is an F-P cavity, and according to the light splitting principle of the F-P cavity shown in fig. 5, the target thickness of each F-P cavity corresponding to different target light wavelengths can be predetermined, so that after the target light wavelength of each pixel point is obtained, the target thickness of each F-P cavity corresponding to each pixel point can be determined, and further, the thickness of each F-P cavity in each pixel point can be adjusted.
In some embodiments, each pixel includes a first F-P cavity and a second F-P cavity; and adjusting the thickness of the first F-P cavity to be a first target thickness and adjusting the thickness of the second F-P cavity to be a second target thickness according to the target optical wavelength.
Specifically, the thickness of each F-P cavity is adjusted to a target thickness of each F-P cavity by an adjustment component in each F-P cavity, depending on the target optical wavelength.

(1) determining a target thickness of each F-P cavity according to the target optical wavelength;
in the embodiment of the application, the transmission peak with the same wavelength between each F-P cavity can be determined according to the wavelength of the target light, and accordingly, the target thickness of each F-P cavity can be determined according to the transmission peak. It can be understood that the wavelength of the unique transmission peak corresponding to each F-P cavity under the condition of different target thicknesses can be determined through preliminary experiments or tests, so that the thickness of each F-P cavity can be directly determined according to the target light wavelength required to be received.
(2) Determining an adjustment voltage corresponding to each F-P cavity according to the target thickness;
the corresponding relation between the adjustment voltage and the target thickness can be determined through experiments or tests in advance, and the corresponding adjustment voltage can be directly determined according to the required target thickness.

And adjusting the thickness of each F-P cavity to the target thickness of each F-P cavity by applying an adjusting voltage corresponding to the adjusting component in each F-P cavity.
Step 604: displaying the target image;
in the embodiment of the application, after the thickness of each F-P cavity is adjusted, only light with the target light wavelength can transmit out of the F-P cavity, so that after white light emitted by a backlight layer of a display screen is filtered by the F-P cavity in each pixel point, the color corresponding to the target light wavelength of the pixel point can be displayed on each pixel point.
