Embodiment one
The embodiment of the present application provides a kind of euphotic cover plate, and Fig. 2 is the structural schematic diagram of the euphotic cover plate, this Shen euphotic cover
Plate includes:
Euphotic cover plate ontology 21；
Light-transmissive film layer 23 is set to 21 first side surface of euphotic cover plate ontology, including is sequentially overlapped setting at least two layers
Light-transmissive film；
Ink layer 22 is set to 21 second side surface of euphotic cover plate ontology；
Wherein, the refractive index of the light-transmissive film adjacent with the euphotic cover plate ontology 21 is greater than the euphotic cover plate ontology 21
Refractive index, and the respective refractive index of at least two layers of the light-transmissive film is passed at a distance from the euphotic cover plate ontology 21 with respective
Subtract；Alternatively, the refractive index of the light-transmissive film adjacent with the euphotic cover plate ontology 21 is less than the refraction of the euphotic cover plate ontology 21
Rate, and the respective refractive index of at least two layers of the light-transmissive film is incremented by a distance from the euphotic cover plate ontology 21 with respective.
Euphotic cover plate ontology 21,21 side of euphotic cover plate ontology are coated with ink layer 22；
At least two layers of light-transmissive film 23 on 21 other side of euphotic cover plate ontology；
Wherein, between the refractive index of any light-transmissive film 23, with the light-transmissive film 23 and the euphotic cover plate ontology 21 away from
From correlation.
Below by this programme is illustrated, in the embodiment of the present application, referring to fig. 2, it is located at the euphotic cover plate ontology
Light-transmissive film 23 on 21 shares two layers, and the first light-transmissive film close to the euphotic cover plate ontology 21 is 23a, far from the light transmission
Second light-transmissive film of cover board body 21 is that 23b, the first light-transmissive film 23a and the second light-transmissive film 23b close contact are seamless.
Preferably, the material of the euphotic cover plate ontology 21 includes glass.
When the material of euphotic cover plate ontology 21 is glass, which is glass plate.Glass plate has
The characteristics of translucency is good, surfacing.Due to its surfacing, other film layers can be preferably carried, are conducive at it
Surface forms other smooth film layers.Under normal conditions, the sheet thickness is very thin, and refractive index is about 1.5, but excessively thin glass
Glass plate is easily broken under external force, and the thickness of the glass plate can be preset according to actual needs.
Preferably, the material of the light-transmissive film layer 23 includes optical cement.
The optical cement specifically can be OCA (Optically Clear Adhesive) optical cement, and OCA optical cement is colourless
Transparent, light penetration often can achieve 90% or more, and cementing strength is good.Due to OCA optical cement can in room temperature or
Solidify under medium temperature, and the feature that cure shrinkage is small, therefore, production technology hardly possible lower to a certain degree can be reduced using OCA optical cement
Degree.In addition, optical cement can preferably blind, be not easy to leave gap in film layer junction, the optical cement surface after solidification is flat
It is whole not easily to fall off, it is preferably light transmission membrane material.
In the present solution, any light-transmissive film refractive index, between the light-transmissive film and the euphotic cover plate ontology away from
From correlation.
The refractive index of light-transmissive film can realize by adulterating, adjusting the modes such as material concentration, in this example, it is assumed that optics
The refractive index of glue is 1.48 or so, and the refractive index of euphotic cover plate ontology is 1.5.The refractive index and light-transmissive film of light-transmissive film are apart from light transmission
The value of cover board body is related, can specifically be divided at least following two situation:
Situation one:
The refractive index of the light-transmissive film adjacent with the euphotic cover plate ontology is greater than the refractive index of the euphotic cover plate ontology, and
The respective refractive index of at least two layers of the light-transmissive film is successively decreased at a distance from the euphotic cover plate ontology with respective.
Fig. 2 shows structure in, the one layer light-transmissive film adjacent with euphotic cover plate ontology 21 is the first light-transmissive film 23a.It is false
If the refractive index of first light-transmissive film 23a is greater than the refractive index of euphotic cover plate ontology 21, then, the refraction of the second light-transmissive film 23b
Refractive index of the rate less than the first light-transmissive film 23a.In this example, it is assumed that the refractive index of the first light-transmissive film 23a is 1.6, and second
The refractive index of light-transmissive film 23b is 1.5.
Euphotic cover plate ontology 21 is reached through ink layer 22 referring to Fig. 3, light m, it is extraneous from 21 directive of euphotic cover plate ontology
During can occur repeatedly reflect and reflection.Wherein, light m reaches connecing for euphotic cover plate ontology 21 and the first light-transmissive film 23a
At contacting surface, the light for being reflected back ink layer direction is reflection light n1.It was reflected when due to wave from optically thinner medium directive optically denser medium
Cheng Zhong, vibration when direction of vibration of the back wave when leaving reflection point reaches incidence point relative to incidence wave differ half week
Phase, this phenomenon are called half-wave loss.Separately since the refractive index 1.6 of the first light-transmissive film 23a is greater than the folding of euphotic cover plate ontology 21
Rate 1.5 is penetrated, therefore, half-wave occurs in reflection light of the light m at the contact surface of euphotic cover plate ontology 21 and the first light-transmissive film 23a
Loss, i.e. reflection light n1Phase and the phase phase difference half period of light m.
Then, some light is transmitted through in the first light-transmissive film 23a in light m, in the first light-transmissive film 23a and the second light-transmissive film
It is reflected at the contact surface of 23b, reflection light n2.Since half-wave loss phenomenon is not present in transmitted ray, it is transmitted through
The phase of some light m in first light-transmissive film 23a and the phase of light m in former euphotic cover plate ontology 21 are identical.
Since the refractive index 1.6 of the first light-transmissive film 23a is greater than the refractive index 1.5 of the second light-transmissive film 23b, part light
When line m reflects at the contact surface of the first light-transmissive film 23a and the second light-transmissive film 23b, there is not half-wave loss in reflection light,
That is reflection light n2Phase it is identical as the phase of light m.
Then, some light m is transmitted through the second light-transmissive film 23b from the first light-transmissive film 23a, since there is no half for transmitted ray
Wave loses phenomenon, therefore, is transmitted through light in the phase and former euphotic cover plate ontology 21 of some light m in the second light-transmissive film 23b
The phase of line m is identical.
Since the refractive index 1.5 of the second light-transmissive film 23b is greater than the refractive index 1.0 of air, some light m is second
When reflecting at the contact surface of light-transmissive film 23b and air, there is not half-wave loss, i.e. reflection light n in reflection light2Phase
It is identical as the phase of light m.
According to above-mentioned analysis it is found that light m is during injection, it is reflected back ink layer direction there are three types of light, is reflected
Light includes n1、n2And n3.Wherein, reflection light n2And n3Phase it is identical as the phase of light m, and reflection light n1Phase
The phase phase difference 180 degree of position and light m.
Reflection light n1After directive ink layer, it is possible to be received by the receiver, make an uproar to form bottom, influence receiver and connect
Receive outer signals.The reflection light n in ink layer direction is reflected back in this programme2And n3With reflection light n1Half of phase phase difference
Wavelength, as reflection light n2Or n3With reflection light n1It when meeting, can cancel out each other, to reduce the reflection that receiver receives
Light n1, and then have the function that reducing bottom makes an uproar.
Situation two:
The refractive index of the light-transmissive film adjacent with the euphotic cover plate ontology is less than the refractive index of the euphotic cover plate ontology, and
The respective refractive index of at least two layers of the light-transmissive film is incremented by a distance from the euphotic cover plate ontology with light-transmissive film.
Fig. 2 shows structure in, the one layer light-transmissive film adjacent with euphotic cover plate ontology 21 is the first light-transmissive film 23a.It is false
If the refractive index of first light-transmissive film 23a is less than the refractive index of euphotic cover plate ontology, then, the refractive index of the second light-transmissive film 23b
It is negatively correlated with the value apart from euphotic cover plate ontology 21.In this example, it is assumed that the refractive index of the first light-transmissive film 23a is 1.4, and the
The refractive index of two light-transmissive film 23b is 1.5.
Referring to fig. 4, light m reaches euphotic cover plate ontology, the mistake from the euphotic cover plate ontology directive external world through ink layer 22
Repeatedly refraction and reflection occur for Cheng Zhonghui.Wherein, light m reaches the contact surface of euphotic cover plate ontology 21 and the first light-transmissive film 23a
Place, the light for being reflected back ink layer direction is reflection light n1.Since the refractive index 1.4 of the first light-transmissive film 23a is less than euphotic cover plate
The refractive index 1.5 of ontology, therefore, reflection light of the light m at the contact surface of euphotic cover plate ontology 21 and the first light-transmissive film 23a
There is not half-wave loss, reflection light n1Phase it is identical as the phase of light m.
Then, some light is transmitted through in the first light-transmissive film 23a in light m, in the first light-transmissive film 23a and the second light-transmissive film
It is reflected at the contact surface of 23b, reflection light n2.Since half-wave loss phenomenon is not present in transmitted ray, it is transmitted through
The phase of some light m in first light-transmissive film 23a and the phase of light m in former euphotic cover plate ontology 21 are identical.
Refractive index 1.5 due to the refractive index 1.4 of the first light-transmissive film 23a less than the second light-transmissive film 23b, part light
When line m reflects at the contact surface of the first light-transmissive film 23a and the second light-transmissive film 23b, there is half-wave loss in reflection light, i.e.,
Reflection light n2Phase and the phase phase difference half wavelength of light m.
According to above-mentioned analysis it is found that light m is during injection, there are at least two light to be reflected back ink layer direction,
Reflection light includes n1And n2.Wherein, reflection light n1Phase it is identical as the phase of light m, and reflection light n2Phase
With the phase phase difference 180 degree of light m.
Reflection light n1After directive ink layer, it is possible to be received by the receiver, make an uproar to form bottom, influence receiver and connect
Receive outer signals.The reflection light n in ink layer direction is reflected back in this programme2With reflection light n1Phase phase difference half wavelength,
As reflection light n and reflection light n1It when meeting, can cancel out each other, to reduce the reflection light n that receiver receives1, in turn
Having the function that, which reduces bottom, makes an uproar.
Technical solution provided by the present application is projecting part in such a way that light-transmissive film is arranged in euphotic cover plate outer body
Signal wave reflect, according to half-wave loss principle, phase and the bottom for the signal wave being reflected back are made an uproar the phase of middle part signal wave
Phase difference half wavelength can offset bottom and make an uproar middle part signal wave, reduce bottom to a certain extent and make an uproar, optimization receives the property of signal wave
Energy.
Embodiment two
The scheme based on the above embodiment, the application also provides a kind of euphotic cover plate, to further illustrate we
Case, as shown in figure 5, euphotic cover plate provided by the present application includes:
Euphotic cover plate ontology 51,51 side of euphotic cover plate ontology are coated with ink layer 52；
At least two layers of light-transmissive film 53 on 51 other side of euphotic cover plate ontology；
Wherein, between the refractive index of any light-transmissive film 53, with the light-transmissive film 53 and the euphotic cover plate ontology 51 away from
From correlation.
As shown in figure 5, in this example, the light-transmissive film positioned at 51 1 surface of euphotic cover plate ontology shares 4 layers, from close to thoroughly
Light cover board body 51 is successively to far from euphotic cover plate ontology 51: the first light-transmissive film 53a, the second light-transmissive film 53b, third light-transmissive film
53c, the 4th light-transmissive film 53d.
Based on the structure shown in Fig. 5, it is assumed that the refractive index of euphotic cover plate ontology 51 is 1.5, according to euphotic cover plate ontology 51
With the index of refraction relationship of the first light-transmissive film 53a, this programme is illustrated by following two example:
Example one:
The refractive index of first light-transmissive film 53a is greater than the refractive index of euphotic cover plate ontology 51, the refractive index of the second light-transmissive film 53b
Less than the refractive index of the first light-transmissive film 53a, refractive index of the refractive index less than the second light-transmissive film 53b of third light-transmissive film 53c, the 4th
The refractive index of light-transmissive film 53d is less than the refractive index of third light-transmissive film 53c.
Based on the structure shown in this example, when there is light from the 52 directive external world of ink layer, the first light-transmissive film 53a and second
The light reflected at light-transmissive film 53b contact surface can offset reflection at euphotic cover plate ontology 51 and the first light-transmissive film 53a contact surface
Light.It is particularly due to the light phase difference half wavelength of above-mentioned two reflection, i.e. difference 180 degree, when two kinds of light meet
When can cancel out each other, make an uproar to reduce bottom.
In this application, due to the first light-transmissive film 53a, the second light-transmissive film 53b, third light-transmissive film 53c and the 4th light-transmissive film
The refractive index of 53d is sequentially reduced, and therefore, is transmitted through extraneous light at adjacent two film layers contact surface from the first light-transmissive film 53a
The light of reflection is identical as the light phase of former euphotic cover plate ontology 51, therefore, not only the first light-transmissive film 53a and the second light transmission
The light reflected at film 53b contact surface can reduce bottom and make an uproar, and at the second light-transmissive film 53b and third light-transmissive film 53c contact surface
The light reflected at the light and third light-transmissive film 53c and the 4th light-transmissive film 53d contact surface of reflection can also drop to a certain extent
It makes an uproar at low bottom.
Example two:
The refractive index of first light-transmissive film 53a is less than the refractive index of euphotic cover plate ontology 51, the refractive index of the second light-transmissive film 53b
Greater than the refractive index of the first light-transmissive film 53a, the refractive index of third light-transmissive film 53c is greater than the refractive index of the second light-transmissive film 53b, and the 4th
The refractive index of light-transmissive film 53d is greater than the refractive index of third light-transmissive film 53c.
Based on the structure shown in this example, when there is light from the 52 directive external world of ink layer, the first light-transmissive film 53a and second
The light reflected at light-transmissive film 53b contact surface can offset reflection at euphotic cover plate ontology 51 and the first light-transmissive film 53a contact surface
Light.It is particularly due to the light phase difference half wavelength of above-mentioned two reflection, i.e. difference 180 degree, when two kinds of light meet
When can cancel out each other, make an uproar to reduce bottom.
In this application, due to the first light-transmissive film 53a, the second light-transmissive film 53b, third light-transmissive film 53c and the 4th light-transmissive film
The refractive index of 53d is sequentially increased, and therefore, is transmitted through extraneous light at adjacent two film layers contact surface from the first light-transmissive film 53a
The light of reflection, and euphotic cover plate ontology 51 are identical as the light phase reflected at the first light-transmissive film 53a contact surface, therefore, no
The light only reflected at the first light-transmissive film 53a and the second light-transmissive film 53b contact surface can reduce bottom and make an uproar, and the second light-transmissive film
At the light and third light-transmissive film 53c and the 4th light-transmissive film 53d contact surface reflected at 53b and third light-transmissive film 53c contact surface
The light of reflection also can reduce to a certain extent bottom and make an uproar.
Based on examples detailed above it is found that the film layer quantity of light-transmissive film 53 is more, then reduces the effect that bottom is made an uproar and be more obvious, still,
In the actual production process, blocked up light-transmissive film 53 can reduce integral light-transmitting, therefore, preferably, at least two layers of light transmission
The overall thickness of film is less than the thickness of the euphotic cover plate ontology.
Scheme provided by the present application can guarantee at least two layers light-transmissive film overall thickness be less than euphotic cover plate ontology thickness, one
Aspect is avoided that light-transmissive film blocked up the case where causing light transmittance to decline, and on the other hand, relatively thin light-transmissive film layer is conducive to be thinned saturating
The integral thickness of light cover board, and then the thickness of the electronic equipment using the euphotic cover plate is advantageously reduced, it is preferably saturating in guarantee
Having the function that under the premise of photosensitiveness, which reduces bottom, makes an uproar.
Preferably, the application also provides a kind of euphotic cover plate, and based on the structure of above-mentioned euphotic cover plate, described at least two layers thoroughly
In light film, the thickness of every layer of light-transmissive film is identical.
When multilayer light transmission film thickness is identical, the solidification deformation quantity of every layer of light-transmissive film is essentially identical, and configuration is relatively steady
It is fixed.The light-transmissive film of same thickness can reduce the technical difficulty of technique production, improve and produce whole yield, avoid due to light transmission film thickness
Spend situations such as film layer separates after different appearance solidify.
