The electrochromic device 100 is attached to the transparent housing 200, and a lens of the camera 300 is disposed corresponding to the electrochromic device 100.

Regarding the structural modifications of the embodiments, those skilled in the art should also make extensions and modifications on the basis of the embodiments within the scope of the present application.

Further, referring to fig. 7, a metal wiring layer 600 is further embedded in the shielding layer 400 in the present embodiment, and the metal wiring layer 600 is electrically connected to the first conductive layer 110 and the second conductive layer 120 respectively. The metal wiring layer 600 may be formed by providing a metal film and then etching the metal film, or may be formed by using a local metal plating, that is, a metal plating is formed at a position where wiring is required, and the metal wiring layer may be made of a metal material having good conductivity, such as molybdenum or aluminum.

The coloring speed of the electrochromic device 100 is mainly related to the following parameters: the smaller the sheet resistance is, the faster the speed is, but if the ITO with low sheet resistance is to be realized, the transmittance cannot be made high, and the high transmittance requirement cannot be realized. On the premise of keeping ITO high transparency, the color changing speed can be improved to the maximum extent by designing the wiring. The solution adopted by the present embodiment is to design the material and shape of the trace. The silver material has very small impedance and is a good choice in terms of material. In addition, the voltage is uniformly distributed in the whole circle, specifically referring to fig. 8, from the aspect of the wiring structure, the larger the cross-sectional area of the wiring is, the lower the resistance is. The following is a data case (obtained by testing with an area of 30 × 30mm as an example) of different parameters, and it should be noted that the ITO with low sheet resistance here includes the first conductive layer 110 and the second conductive layer 120.

From the data table, it can be found that, when the ITO impedance is constant, the cross-sectional size of the silver wire is increased, and the coloring speed of the electrochromic device can be greatly improved. Therefore, the width of the wire is between 0.5 mm and 1mm, and the coloring speed is good when the thickness is 0.01 mm to 0.02 mm. Here, it should be noted that in the embodiment of fig. 1 and 3, a trace connecting the first and second conductive layers is also provided, and the structure may be similar to that in the present embodiment.

In addition, the fading speed of the electronic color changing module 100 is related to the discharge speed, and when the voltage is removed, the color changing material layer 130 begins to fade, but the fading speed is slow, and the optimal design is performed through a circuit to achieve fast fading. The technical scheme adopted in the embodiment is as follows: by applying a ringing voltage and then switching to a short circuit. If the ringing voltage is sustained, the material will fade to recolor. Therefore, the control of the switching time becomes important, and the present embodiment gives the data referred to below (similarly obtained by performing a test using an electronic color changing module having an area of 30 × 30mm as a sample).

Fade rate in normal open circuit	Short circuit fade rate	Ringing voltage + short circuit fade rate
			about 1-3s	about 0.5-1s	About 0.3-0.5s

Wherein the suggested duration for the reverse voltage is 0.2-0.5s, then quickly switched to the short-circuit mode, and finally switched to the off mode after fading.

According to the embodiment of the application, the response speed of the electrochromic device can be improved by designing the wiring structure and optimizing the driving voltage. Thereby reducing the response time of the electronic color changing module; wherein the response speed includes a coloring speed and a fading speed.

Referring to fig. 9, the electronic device includes an electrochromic device 100, a transparent housing 200, a camera 300, and an appearance film 700. In the embodiment, the appearance film layer 700 is disposed between the electrochromic device 100 and the transparent casing 200. In some other embodiments, the electrochromic device 100 may be sandwiched between the appearance film layer 700 and the transparent casing 200.

Referring to fig. 10, the appearance film 700 includes a transparent area 710 and a color area 720, and the camera is disposed corresponding to the transparent area 710, wherein the transparent area 710 may be a light hole or a light-transmitting through hole, i.e., a hole; the transparent area 710 may also be a transparent area with a substrate, and the shape of the transparent area 710 may be circular to fit the lens of the camera 300.

The color zone 720 is used for cooperating with the electrochromic device 100 to make the electronic device present a color-changeable appearance effect. Wherein the appearance effect is observed from the outside of the transparent case 200. The color region in this embodiment may include a third substrate, and at least one of an ink layer and an optical coating layer stacked on the third substrate. Specifically, referring to fig. 11, the appearance film color region 720 of the present embodiment includes a third substrate 721, an optical coating layer 722 and an ink layer 723.

it should be noted that the illustration of the present embodiment only shows a laminated structure of the appearance film layer color region 720, and the appearance film layer color region 720 may be a laminated structure of the third substrate 721 and the optical coating layer 722 only in some other modified embodiments, a laminated structure of the third substrate 721 and the ink layer 723 only, or the ink layer 723 is sandwiched between the optical coating layer 722 and the third substrate 721, or the ink layer 723 and the optical coating layer 722 are respectively disposed on two sides of the third substrate 721.

Optionally, the appearance film layer color area 720 is formed by forming each functional layer on the same side of the third substrate 721, so that the side on which the functional layers are disposed and the second conductive layer 120 of the electrochromic device 100 can be connected through the adhesive layer (not shown). The functional layers referred to herein include an optical coating layer 722, an ink layer 723, and the like. The appearance film layer 700 may be a single structure, that is, the appearance film layer 200 is a sheet or film structure separately manufactured, and is fixedly connected to the electrochromic device 100 by adhesion; in this embodiment, the appearance film layer 200 is fixedly connected to the first conductive layer 110.

Further, with reference to fig. 9, the electronic device further includes an antireflection film 800, where the antireflection film 800 is disposed on a surface of the transparent casing 200 away from the electrochromic device 100, that is, a surface of the transparent casing 200 away from the appearance film layer 700. Of course, in some other embodiments, the antireflection film 800 may also be disposed on the surface of the appearance film layer 700, or (for example, in the embodiment of fig. 3) may be disposed on the surface of the protective layer or the side of the first substrate 140 away from the second conductive layer 120, or disposed at multiple positions at the same time. The specific arrangement position of antireflection film 800 is not limited here. The material of the anti-reflection film 800 may be calcium fluoride, which reduces reflection and increases light transmittance.

In the electronic device of the present embodiment, the appearance film layer is provided, so that a color-changeable appearance effect can be exhibited.

Referring to fig. 12, the electronic device includes an electrochromic device 100, a transparent housing 200, a camera 300, an appearance film layer 700, and a substrate color layer 900. The substrate color layer 900 and the appearance film layer 700 are respectively disposed on two opposite sides of the electrochromic device 100, the substrate color layer 900 is provided with a light-transmitting through hole 910, the light-transmitting through hole 910 corresponds to the transparent area 710 of the appearance film layer 700, and it is ensured that the substrate color layer 900 does not block the camera 300.

The specific structure of the substrate color layer 900 may be: a colored layer such as an ink layer or a metal plating film is formed on the first substrate or the second conductive layer of the electrochromic device 100.

in the electronic apparatus according to the present embodiment, a laminated structure of the electrochromic device 100, the appearance film layer 700, and the substrate color layer 900 is provided in a region not corresponding to the camera 300, so that a more rich appearance effect can be superimposed.

Referring specifically to fig. 13, a green appearance film 700 and a white substrate color layer 900 are illustrated. The transmittance of the electrochromic device 100 can vary from 0% (completely opaque) to 100% (completely transparent), and at intermediate values, it is in a semi-transparent mode between opaque and completely transparent. Firstly, assuming that the transmittance of the electrochromic device 100 is 0, when we look at the light path 1, the light in the light path 1 penetrates the appearance film layer 700, and then is refracted by the black (or dark) electrochromic device 100, and the color shown by the refracted light path 1 is the superposition of the green color of the appearance film layer 700 and the black electrochromic device 100, namely purple; when the light path 2 is viewed again, and the light path 2 indicates that the transmittance of the electrochromic device 100 is 100%, at this time, light can sequentially pass through the appearance film layer 700 and the electrochromic device 100 and be refracted by the substrate color layer 900, and the color shown by the refracted light path 2 is the superposition of the green color of the appearance film layer 700 and the white substrate color layer 900, that is, is green; the light path 3 is represented in a semi-transparent state between 0% (completely opaque) and 100% (completely transparent) of the transmittance of the electrochromic device, at this time, light of the light path 3 can sequentially pass through the appearance film layer 700 and the electrochromic device 100 in the semi-transparent state and be refracted by the substrate color layer 900, the color represented by the refracted light path 3 is the superposition of the appearance film layer 700 green, the semi-transparent electrochromic device 100 and the white substrate color layer 900, and the light path 3 can present any color between green and purple in the color band according to the difference of the transmittance of the electrochromic device 100.

In addition, in the embodiment, only the green appearance film layer 700 and the white substrate color layer 900 are used in combination, when the color combination of the appearance film layer 700 and the substrate color layer 900 is changed, and the electrochromic device 100 is controlled to change different transmittances, the color change effect of almost any color can be obtained. Therefore, as can be seen from the above analysis, the electrochromic device according to the present embodiment can superimpose a rich appearance effect by providing the laminated structure of the electrochromic device 100, the appearance film layer 700, and the substrate color layer 900.

The electrochromic device 100 is completely embedded in the sinking groove 201, but in some other embodiments, a part of the structure may protrude from the sinking groove 201, and those skilled in the art can select the part of the structure according to actual design requirements.

Optionally, the electrochromic device 100 includes a first conductive layer 110, a color-changing material layer 130, and a second conductive layer 120 sequentially stacked along a depth direction of the sinker 201, where the first conductive layer 110 is disposed on a bottom surface of the sinker 201. Further, the electrochromic device 100 may further include a first substrate 140 disposed on an outer surface of the second conductive layer 120, wherein the first substrate 140 may serve as a cover, a protector, and a support for the second conductive layer 120.

Further, referring to fig. 17, different from fig. 16, the transparent casing 200 in this embodiment is provided with a through containing hole 202, the containing hole 202 is disposed corresponding to the camera 300, and the electrochromic device 100 is embedded in the containing hole 202. Optionally, the electrochromic device 100 includes a first substrate 140, a first conductive layer 110, a color-changing material layer 130, a second conductive layer 120, and a second substrate 170, which are sequentially stacked along the axial direction of the accommodating hole 202.

The detailed structural features of this section are not described herein again.

in the electronic device in the embodiment, the sinking groove or the accommodating hole structure is arranged on the transparent shell, and the electrochromic device is arranged in the sinking groove or the accommodating hole, so that the electronic device can play a good role in protecting the electrochromic device on one hand, and can reduce the thickness of the whole structure of the electronic device on the other hand, thereby saving space.

Referring to fig. 18, the electronic device of the present embodiment includes an electrochromic device 100, a transparent casing 200, a camera 300, and an appearance film 700. The appearance film 700 is attached to the transparent casing 200, the light-transmitting area of the appearance film 700 is a light-transmitting through hole, and the optical adhesive 500 is filled inside the light-transmitting through hole. The electrochromic device 100 is disposed corresponding to the light-transmitting region of the appearance film 700, and the camera is disposed corresponding to the electrochromic device 100.

alternatively, the electrochromic device 100 in this embodiment is illustrated as including a dual substrate structure. Different from the foregoing embodiments, the electrochromic device 100 further includes an antireflection film layer 180, wherein the antireflection film layer 180 is respectively disposed between the first substrate 140 and the first conductive layer 110, on the second substrate 170 and the second conductive layer 120, and on the surfaces of the second substrate 170 on the side far from the second conductive layer 120.

It should be noted that in some other embodiments, the antireflection film 180 may be disposed at one or more positions, and the antireflection film 180 may be disposed between adjacent dielectric layers with different refractive indexes. The antireflection film 180 is a transparent film that attenuates reflected light and is formed according to the principle of film interference. Generally, the multilayer film structure may have a better antireflection effect, so the antireflection film 180 in the embodiment of the present application may also be a stacked film structure of the multilayer film structure, and according to the antireflection principle of the antireflection film, the refractive index of the antireflection film satisfies the formula: in the formula, n1 and n2 are respectively expressed as the refractive indexes of two dielectric layers adjacent to the antireflection film; and n represents the refractive index of the antireflection film. Taking air and the second substrate 170 (glass) as an example, the refractive index of the antireflection film on the surface of the second substrate 170 away from the second conductive layer 120 is certainly the same, the antireflection film 180 itself may also be formed by stacking a plurality of layers, and the sub-stacked structures of adjacent antireflection films all satisfy the formula

Alternatively, the material of antireflection film 180 may be Al2O3, MgF2, Bi2O3, etc., and the thickness of antireflection film 180 is generally one-fourth of the wavelength of light. Of course, simply increasing the number of the film layers does not lead to unlimited improvement of the antireflection effect, and it is also closely related to the design of the film thickness, the selection of the film material, and the like, and detailed technical features regarding the material and thickness design of the antireflection film are not described in detail herein.

Referring to fig. 19, the electronic device in this embodiment also includes an electrochromic device 100, a transparent casing 200, a camera 300, and an appearance film 700. Different from the previous embodiment, the electrochromic device 100 is a single-layer substrate structure, the first conductive layer 110 is directly disposed in the transparent region of the appearance film layer 700, an antireflection film 180 is disposed between the appearance film layer 700 and the transparent casing 200, the antireflection film 180 is disposed between the first substrate 140 and the second conductive layer 120, and the antireflection film 180 is disposed on the surface of the first substrate 140 away from the second conductive layer 120. Similarly, the refractive index of the anti-reflection film 180 satisfies the formula taking the anti-reflection film 180 between the first substrate 140 and the second conductive layer 120 as an example, generally, the refractive index of the second conductive layer 120 (made of ITO) is about 1.78, and the refractive index of the first substrate 140 (made of glass as an example) is 1.5, so the refractive index of the anti-reflection film 180 disposed between the first substrate 140 and the second conductive layer 120 is about 1.78

Referring to fig. 20, an electronic device in this embodiment is different from the embodiment in fig. 18 in that an antireflection film 180 and a protection film 190 are further disposed on a surface of the transparent casing 200 away from the electrochromic device 100 in this embodiment. The protection film 190 may include an AF film (Anti-Fingerprint film), a DLC film (Diamond-like carbon film), and the like. The AF film may be used to prevent fingerprint residues, and the DLC film is used to increase the wear resistance of the outer surface of the transparent case 200. The protective film 190 may be provided with only one of the AF film and the DLC film, or may be provided with both of them, and in the case where both of them are provided, the DLC film is provided on the outermost surface. For detailed technical features of antireflection film 180, refer to the related description of the foregoing embodiments.

in addition, in the electronic device structure in the embodiment of fig. 19, the antireflection film 180 and the protection film 190 may also be disposed on the surface of the transparent casing 200 on the side away from the electrochromic device 100.

Among them, the flash lamp 301 may emit light through the electrochromic device 100 and the transparent case 200 when the electrochromic device 100 is in a transparent or translucent state. The flash 301 may be arranged on a middle frame or a circuit board (indicated by reference numeral 88) of the electronic device alongside the camera 300, or may be arranged at another position, which is not specifically limited herein.

Optionally, the sensing module 302 may include a light sensor module 3021, a proximity sensor module 3022, and the like, where the light sensor module 3021 is used to collect ambient light, that is, sense ambient light conditions, and enable the processing chip to automatically adjust the backlight brightness of the display, thereby reducing power consumption of the product. Because the display consumes up to 30% of the total battery capacity, the use of the ambient light sensor can extend the operating time of the battery to the maximum. Ambient light sensors, on the other hand, help the display to provide a soft picture. When the ambient brightness is high, the LCD using the ambient light sensor will automatically adjust to high brightness. When the external environment is dark, the display will turn to low brightness. The conventional optical sensor module 3021 includes a photo resistor, a photodiode, a photo transistor, a silicon photocell, and the like.

The proximity sensor module 3022 is a device capable of sensing the proximity of an object, and recognizes the proximity of the object by using the sensitivity of the displacement sensor to the approaching object, and outputs a corresponding switch signal, so the proximity sensor is also generally called a proximity switch. Movement and presence information of the object can be detected and converted into an electrical signal. In particular, the method can be used for assisting in controlling the lighting and extinguishing of the display screen of the electronic device. The installation position of the sensing module 302 is not limited to the situation in the figure.

The electronic device provided by the embodiment can simultaneously realize shielding and exposure of functional devices such as the camera, the flash lamp and the sensing module.

Referring to fig. 22, the electronic device includes a rear cover 10, a screen 20 and a camera 300. The rear cover 10 is connected with the screen 20, and a containing space 1001 is formed between the rear cover 10 and the screen 20; the camera 300 is located in a receiving space 1001 formed by the rear cover 10 and the screen 20.

In particular, the rear cover 10 may comprise a color change device that is switchable between a first state, which is a non-transparent state or a translucent state, and a second state, which is a transparent state. The camera 300 captures an image through the color changing device when the color changing device is in a transparent state, wherein the transparent state includes a fully transparent state and various semi-transparent states between the fully transparent state and the non-transparent state. Specifically, the non-transparent or non-transparent state is that the user cannot perceive the camera through the rear cover with naked eyes, that is, the effect of completely hiding the camera is achieved; the semi-transparent or semi-transparent state is that a user can see the outline of the camera through the rear cover by naked eyes, so that the effect of at least partially hiding the camera is achieved; the full transparency or full transparency state allows the user to see the camera profile and specific structural details through the back cover.

Optionally, the color-changing device is an electrochromic device, the electrochromic device can be switched from a non-transparent state to a transparent state in response to an electrical signal, and the camera 300 collects an image when the electrochromic device is in the transparent state, and for detailed structural features of the color-changing device being the electrochromic device, reference is made to the related description of the foregoing embodiment, and details are not repeated here.

In addition, the color changing device may also be a piezochromic device, the piezochromic device may be switched from a non-transparent state to a transparent state in response to a pressure signal, and the camera 300 collects an image when the piezochromic device is in the transparent state. Specifically, a piezochromic device or a piezochromic material layer may be provided on one side surface of the rear cover 10, or the rear cover 10 itself may be made of a piezochromic material.

the piezochromic material (also called mechanoluminescence chromotropic material) is an intelligent material whose luminescence color is obviously changed under the action of external force, such as pressure, shearing force, stretching force, etc. The method is widely applied to the fields of stress sensors, trademark anti-counterfeiting, memory chips, data storage, optical recording and the like. The piezochromic material includes a piezochromic material and a piezochromic material according to different light emitting principles. The change of the chemical structure of the material molecule and the change of the aggregation state structure under the action of external force are two ways for realizing the piezoluminescence color change of the material. The molecular chemical structure is changed by the action of external force, and the piezoluminescence color change is realized by utilizing different molecular structures to emit light with different colors before and after stress. For example, a colorless polymer having a spiropyran structure is converted into a polymer having a merocyanine structure whose ring is opened to red by an external force, a divinylanthracene PAIE compound, or the like.

further, the color changing device is a color changing device associated with temperature, the color changing device can be switched from a non-transparent state to a transparent state in response to a temperature signal, and the camera 300 collects an image when the color changing device is in the transparent state.

The thermochromic material may be a reversible thermochromic material, such as aminophenyl mercury dithizonate, dimethylaminobenzazobenzene, titanium dioxide, and dimethyl cellulose. The material type and the color change principle regarding thermochromic will not be described in detail here.

Several working process states of the electronic device are as follows, and the principle of using the color-changing device as an electrochromic device is explained. (1) Firstly, starting a camera, namely in a shooting state, starting an electrochromic device to change color, converting a shielding state, namely an opaque state, into a transparent state, finishing shooting by the camera, closing the camera, starting the electrochromic device to change color in a reverse direction, and converting the transparent state into the shielding state; (2) the method comprises the steps that firstly, an electrochromic device is started to change color, a shielding state, namely an opaque state, is changed into a transparent state, when the electrochromic device is completely changed into the transparent state, a camera is started to work and complete shooting, the camera is closed, the electrochromic device is started to change color in a reverse direction, and the transparent state is changed into the shielding state to hide the camera. It should be noted that, in the above two working state processes, after the camera finishes shooting, the two processes of turning off the camera and turning on the electrochromic device to reverse color change may be performed simultaneously or any one of the two processes may be performed first, and no specific limitation is made here.

Further, the electrochromic device also has two states, a blocking state, which we can call as a default state; and a non-shielding state, which is called as an operating state, wherein the shielding state can be a power-on state of the electrochromic device, that is, when the electrochromic device changes from the shielding state to the non-shielding state, the power-on of the electrochromic device is stopped, or a reverse voltage is applied to the electrochromic device, wherein the reverse voltage is applied to accelerate the color change speed of the electrochromic device. When the electrochromic device changes from the non-shielding state to the shielding state, the electrochromic device may be powered on. In addition, the shielding state of the electrochromic device can also be a non-energized state, that is, when the electrochromic device changes from the shielding state to the non-shielding state, the electrochromic device can be energized, and when the electrochromic device changes from the non-shielding state to the shielding state, the energization of the electrochromic device is stopped or reverse voltage is applied to accelerate the color change speed of the electrochromic device.
