Different color out, wherein complex light refers to the visible light comprising different-waveband, such as sunlight.
For graphene film, the graphene film of different shapes can reflect the visible light of different-waveband, thus
Graphene film of different shapes is caused to show different colors.Usual graphene film is in bubble shape, and atmospheric pressure changes
When change, the bubble shape of graphene film has corresponding variation.For example, being in bubble shape when atmospheric pressure becomes larger
Graphene film will receive extruding, so that the recess that the shape of graphene film will be opposite is in when atmospheric pressure becomes smaller
The graphene film of bubble shape will be opposite protrusion.In short, with the change of atmospheric pressure, the shape of graphene film
Have a corresponding change, and graphene film of different shapes be to the reflection case of complex light it is different, it is of different shapes
After graphene film carries out different degrees of reflection to complex light, different reflected lights is formed, different reflected lights is transmitted to
In human eye or sensor devices, graphene film of different shapes is resulted in show different colors.To sum up, in difference

The method for preparing graphene film is not restricted.Display screen includes graphene film, refers to that graphene film belongs to display screen,
For example, display screen can also include substrate, then graphene film can be covered in substrate.
Wherein, graphene film can be the graphene of single layer structure, be also possible to the graphene of double-layer structure, Huo Zheye
It can be the graphene of more layers structure.Specifically, compared to the graphene of single layer structure, double-layer structure or more layers structure
Graphene albedo it is stronger, wherein stronger do not imply that of albedo can reflect further types of visible light, but
Refer to that the intensity for the visible light that graphene film can reflect specific band is bigger.Incident light passes through double-layer structure or more layers
After the graphene film of structure, more light can be reflected by graphene film, that is, human eye or sensor devices can be adopted
The more reflected lights collected, so that the color that graphene film is presented is more obvious, to measure the dress of atmospheric pressure
Measurement is set to be more easier to collect the color of graphene film presentation.
In order to illustrate more clearly of the structure for the display screen for including graphene film, referring to figure 2., display screen includes graphite
Alkene film 210 and substrate 220.Further, fluted 221 are arranged in substrate 220, graphene film 210 is sealed in groove 221
Upper surface, will form cavity between groove 221 and graphene film 210.
In the embodiment of the present application, groove 221 can not only support graphene film 210, can also be graphene film 210
The change of shape provides space.Cavity is formed between groove 221 and graphene film 210, the shape of the cavity also can be with stone
The shape of black alkene film 210 changes and changes, which can reduce the absorption to light relative to solid matter, to improve
The albedo of graphene film 210, so that the color of the presentation of graphene film 210 is more obvious, wherein cavity can
To be considered as inside as gaseous material, gaseous material is usually air, and gaseous material is generally to the absorbability of light relative to solid
The absorbability of the light of substance is smaller, and reflection of the gaseous material generally to the albedo of light relative to the light of solid matter
Ability is stronger, therefore cavity is capable of the albedo of opposite raising graphene film 210, so that graphene film 210 is in
Existing color is more obvious.
Specifically, graphene film 210 is sealed in the upper surface of groove 221, groove 221 can have one or more, stone
A cavity, graphene film 210 and N number of groove can be formed between black alkene film 210 and each groove 221 of substrate 220
Will form N number of cavity between 221, wherein N is positive integer, be in Fig. 2 for being provided with 2 grooves 221 in substrate 220, but
The embodiment of the present application is not intended to limit the quantity of the groove 221 in substrate 220.Wherein, the graphene film being covered in substrate 220
210 be usually the membrane structure of an entirety, but because can form one between graphene film 210 and each groove 221
A cavity for convenience or is easy to understand, and graphene film 210 corresponding on a cavity is interpreted as one herein
A graphene film 210, in fact, the graphene film 210 covered on a cavity is intended only as whole graphene film
210 a part.
The color data of graphene film, N number of groove 221 can be more easily acquired in order to measure the device of atmospheric pressure
May be sized to it is identical, wherein the size of groove 221, shape and size including groove 221, for example, two are recessed
The size of slot 221 is identical, refers to that the shape of the two grooves 221 is identical, size is also identical.When size all phases of N number of groove 221
Meanwhile the shape of the N number of cavity formed between N number of groove 221 and graphene film 210 is also, that is, any two
The shape that corresponding graphene film 210 is presented under identical atmospheric pressure on a groove 221 also can be it is the same, also with regard to table
Show that the color data of the graphene film 210 covered on N number of groove 221 is the same.Then the device of atmospheric pressure is surveyed every time
When amount, the color data of the graphene film 210 covered on any one groove 221 can be acquired, the color data is just
It can be used as the color data of graphene film 210, in this way, when the device of measurement atmospheric pressure acquires color data every time, no
It needs to be accurately positioned acquisition position, so that collection process is more simple.
Make the size for the N number of groove 221 being arranged in substrate all identical, possible production difficulty is larger, so in order to drop
Low production difficulty, can also by N number of groove 221 at least one groove 221 be dimensioned to it is big with other grooves 221
Small difference.Because the size of N number of groove 221 is not exactly the same, then the N formed between N number of groove 221 and graphene film 210
The shape of a cavity be also it is not exactly the same, the shape of the graphene film 210 covered on N number of cavity is also with regard to incomplete phase
Together, this also mean that color data of the graphene film 210 covered on every two groove under identical atmospheric pressure is can
It can be discrepant.Therefore, when the size of N number of groove 221 is not exactly the same, in order to obtain more accurate color data,
The device of measurement atmospheric pressure requires to acquire the graphene film 221 covered on the same cavity when measurement every time
Color data.
Wherein, the material of substrate 220 is, for example, silica, because earth silicon material itself just has many grooves
221, so directlying adopt material production substrate 220, then the substrate 220 will carry groove 221.That is, if adopting
Substrate 220 is done with earth silicon material, then without performing etching to form groove 221 to substrate 220, to simplify band groove
The production process of 221 substrate 220.And the albedo of silica is stronger, relatively reduces the loss of incident light, that is, enters
Penetrating light will not be lost because of being absorbed by substrate 220, so that the intensity of the reflected light of graphene film 210 is relatively enhanced,
So that the color that graphene film 210 is presented is more obvious.Certainly, the material of substrate 220 is without being limited thereto, such as substrate
220 material is also possible to glass or other substances.
On the basis of the structure of above-mentioned display screen, the method for the color data for acquiring the display screen is carried out below detailed
Introduction.Wherein, color data can be understood as the data of the color for characterizing graphene film presentation.Characterize the number of color
According to there are many kinds of types, therefore, color data can also be there are many kinds of type.Such as color data can be red green blue tricolor
It is worth (RedGreenBlue, RGB), wherein red value range is 0~255, and green value range is 0~255, blue
Value range be 0~255, any one or several value differences in tristimulus values just represent different colors.
For example, color data is rgb value, and R is 255, G 0, B 0, is recorded for convenience, the color data can be denoted as (255,
0,0), then the color data (255,0,0) means that the color that the graphene film is presented is pure red.Alternatively, color data
It is also possible to black four color value (CyanMagentaYellowBlack, CMYK) of green reddish yellow, as long as in short, the color data being capable of table
Show the color of graphene film, the form of the specific color data is herein with no restriction.The dress of specific acquisition atmospheric pressure
The color data of the display screen of acquisition terminal equipment is set, including but not limited to such as under type:
Mode one, acquire graphene film upper surface reflected light color data, according to the color data of reflected light
Obtain color data.
As it was noted above, the degree of reflection of 210 pairs of light of graphene film of different shapes is different, therefore, atmosphere is measured
The device of pressure can acquire the reflected light of the upper surface of graphene film 210, wherein the thickness very little of graphene film 210,
Therefore graphene film 210 is considered as including upper and lower surfaces.It is object of reference with groove 221 or substrate 220, close to recessed
Perhaps substrate 220 is the separate groove 221 in lower surface to slot 221 or substrate 220 is upper surface.With display screen shown in Fig. 2
For, the one side for being relatively distant from substrate 220 is then the upper surface of graphene film, and the one side of relatively close substrate 220 is then stone
The lower surface of black alkene film 210.Measure the color of the reflected light of the upper surface of the device acquisition graphene film 210 of atmospheric pressure
Data, wherein color data is obtained according to the color data of reflected light and refers to that color data represented by reflected light is exactly graphite
The color data of alkene film 210, that is to say, that the color data of the reflected light of the upper surface of graphene film 210 is obtained,
Just obtain the color data of graphene film 210.
Mode two, acquisition penetrate the color data of the light of graphene film 210, according to the light through graphene film 210
Color data obtain display screen color data.
The degree of reflection of 210 pairs of light of graphene film of different shapes is different, also means that graphite of different shapes
The light that alkene film 210 can penetrate is also different, wherein through the light of graphene film 210, refers to light by graphene
The upper surface of film 210, into the lower surface of graphene film 210, then the light of the lower surface of graphene film 210 is interpreted as
The light of graphene film 210 is crossed, for convenience, the light that hereinafter will transmit through graphene film 210 referred to as penetrates light.Wherein,
The content of the upper and lower surfaces of graphene film can be with reference to the content being described above, and details are not described herein again.Measure atmosphere
The device of pressure can acquire the color data through light, and the color data through light is exactly the number of colors of graphene film 210
According to.
Specifically, thin in order to clearly demonstrate the graphene acquired in display screen shown in Fig. 2 in the way of above two
The detailed process of the color data of film 210, is illustrated below with reference to Fig. 3.For example, incident light a is sunlight, i.e. incident light a
Contain the visible light of various different-wavebands.Specifically, incident light a is incident on the upper surface of graphene film 210, graphene is thin
The upper surface of film 210 can reflect the visible light of a part of wavelength band in incident light a, and the visible light that this part is reflected is as schemed
Reflected light c shown in 3.In addition graphene film 210 can also absorb the visible light of a part of wavelength band in incident light a,
In, absorption can be understood as this part light by being depleted after graphene film 210.Furthermore graphene film 210 can also be saturating
The visible light of a part of wavelength band is crossed, this part transmission light b as shown in Figure 3 through the light of graphene film.
Therefore, it is surveyed in the embodiment of the present application referring to the method for the color data of two kinds of acquisition display screens described above
The device of amount atmospheric pressure can acquire reflected light c and obtain the color data of graphene film 210, or can also acquire transmission
The color data of light b acquisition graphene film 210.Referring to above content it is found that when atmospheric pressure change when marquis, graphene
The shape of film 210 can also change with the variation of atmospheric pressure.Incident light a in so Fig. 3 passes through stone of different shapes
After black alkene film 210, the visible light that the reflected light of acquisition is included is different, it is clear that acquisition included through light
Visible light be also it is different, then measure atmospheric pressure device acquire different reflected light under different atmospheric pressures or
The color data for acquiring the different transmitted lights under different atmospheric pressures can obtain the corresponding number of colors of different atmospheric pressures
According to.
Since the light through graphene film 210 is for the reflected light of graphene film 210, intensity is smaller, because
The intensity of the collected reflected light of the method for this employing mode one is bigger, so that the device of measurement atmospheric pressure more holds
Easily collect the color data of graphene film 210, that is to say, that the device pass-through mode one for measuring atmospheric pressure acquires color
When data, the sensitivity for measuring the device of atmospheric pressure is relatively higher.But in the method for mode one, because of graphene film
210 upper surface be exposed to it is outer, so compared to 210 lower surface of graphene film, the upper surface of graphene film 210 is more
It is easy to be influenced by external environment, such as 210 upper surface of graphene film is easy to appear impurity to influence the color of acquisition
The accuracy of data, therefore the accuracy that mode two acquires comparatively may be higher.So, which kind of mode is selected to obtain actually
Color data is obtained, can be defaulted by the device, or can be selected by user, such as user can select according to the actual situation.
Wherein, the sensitivity for measuring the device of atmospheric pressure refers to that the device of measurement atmospheric pressure being capable of collected graphite
The smallest variation degree of the color of alkene film 210.Because of reflected light or stronger, the graphene film 210 through the intensity of light
The saturation degree of the color of presentation is higher, and the color that corresponding graphene film 210 is presented is more obvious, then measures the dress of atmospheric pressure
Set the color data more easy to collect to display screen.Opposite, if reflected light or too small, the graphite through the intensity of light
The saturation degree for the color that alkene film 210 is presented is lower, then the device for measuring atmospheric pressure is just more difficult to collect the color of display screen
Data.Therefore, in order to improve measurement atmospheric pressure device acquisition color data sensitivity, it is necessary to raising be described above
Reflected light or through light intensity.That is, improving reflected light or the intensity through light, then atmospheric pressure is measured
The sensitivity of the atmospheric pressure of device measurement is higher.
Further, in order to improve measurement atmospheric pressure device measurement atmospheric pressure sensitivity, groove 221 it is straight
Diameter is set as 0.6mm to 0.9mm, when the diameter of groove 221 is set as 0.6mm to 0.9mm, measures the dress of atmospheric pressure
Set the color data for being easier to collect display screen.
Specifically, because groove 221 diameter be 0.6mm between 0.9mm when, the length of the groove 221 is stone
The integral multiple of the wavelength of black 210 reflected light of alkene film, that is to say, that the chamber of the formation between groove 221 and graphene film 210
Body is substantially to be equal to an optical resonator.Incident light is after optical resonator, and the loss of light is smaller, and even having can
Energy optical resonator can amplify incident light, in short, the substantial light for entering intra resonant cavity is humorous compared to no composition
The intensity of the light into cavity in the case where vibration chamber is bigger.That is, incident light is by the damage after the optical resonator
Consumption is smaller, so that through the opposite increase of intensity of light, while the also opposite increase, and then graphene film of the intensity of reflected light
210 colors presented are with regard to more obvious, so that the device of measurement atmospheric pressure is easier to collect the number of colors of display screen
According to the sensitivity of the i.e. atmospheric pressure of the device measurement of measurement atmospheric pressure is higher.
The device of atmospheric pressure is measured after the color data for obtaining above-mentioned display screen, is needed according to color data, and
Corresponding relationship between color data and atmospheric pressure, to obtain current atmospheric pressure.Wherein, corresponding relationship indicates number of colors
According to the relationship between atmospheric pressure.If it is known that some color data, can obtain the color data from the corresponding relationship
The value of corresponding atmospheric pressure.
Obviously, it before using the corresponding relationship between color data and atmospheric pressure, needs first to obtain the corresponding relationship.
For example, a kind of method for obtaining the corresponding relationship is the color for acquiring the graphene film under a variety of atmospheric pressures
Data are obtained with the corresponding relationship according to the color data under a variety of atmospheric pressures and a variety of atmospheric pressures.
Wherein, a variety of atmospheric pressures are to participate in obtaining the atmospheric pressure of the corresponding relationship.A variety of atmospheric pressures can be use
Family often measures the atmospheric pressure that can be used, such as a variety of atmospheric pressures are normal atmospheric pressure 101Kpa.Alternatively, a variety of atmosphere
Pressure is also possible to the arbitrary atmospheric pressure within the scope of some, that is to say, that a variety of atmospheric pressures are the big of limitless number amount
Atmospheric pressure, such as a variety of atmospheric pressure values are 0Kpa to 60Mpa, i.e., a variety of atmospheric pressures include 0Kpa into 60Mpa
Any one or more atmospheric pressures, wherein Kpa is the unit kPa of atmospheric pressure, and Mpa is the unit megapascal of atmospheric pressure,
And 1Mpa is equal to 1000Kpa.
According to a variety of atmospheric pressures and the corresponding multicolour data of a variety of atmospheric pressures, then corresponding relationship is obtained.It is right
It should be related to that there are many kinds of forms, for example, a kind of corresponding relationship of corresponding relationship between occurrence.
Specifically, directly acquiring the corresponding a variety of color data of a variety of atmospheric pressures one by one, obtain between occurrence
Corresponding relationship.The device of measurement atmospheric pressure can be the multicolour data directly acquired one by one under a variety of atmospheric pressures,
Then the corresponding relationship between a variety of atmospheric pressures and corresponding multicolour data acquisition occurrence is directly obtained.Wherein, it adopts
Collect the method for the color data under some atmospheric pressure referring to the content discussed above, details are not described herein again.Between occurrence
Corresponding relationship refers to that atmospheric pressure is specific numerical value, color data be also specific numerical value.
For example, the device of measurement atmospheric pressure collects the RGB data of graphene film at atmospheric pressure 101Kpa
For (255,255,255)；Atmospheric pressure be 202Kpa under, collect graphene film RGB data be (211,211,
211)；In the case where atmospheric pressure is 303Kpa, the RGB data for collecting graphene film is (158,162,173).Then, it measures
The device of atmospheric pressure can be generated according to a variety of atmospheric pressures obtained above and corresponding color data such as the following table 1 institute
Corresponding relationship between the occurrence shown:
Table 1
| Atmospheric pressure | Color data |
| 101Kpa | (255,255,255) |
| 202Kpa | (201,141,201) |
| 303Kpa | (158,162,173) |
Alternatively, a kind of corresponding pass of corresponding relationship between a certain range of atmospheric pressure and corresponding color data
