This application claims priority to the Chinese Patent Application No. 201510349823.X, filed on Jun. 23, 2015, entitled “ELECTRONIC DEVICE” which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of electronic technology, and in particular, to an electronic device.
Currently, a color of an appearance of an electronic device primarily depends on a color of material with which a casing thereof is made. For example, a casing of a Notebook Computer (NB) is made of Carbon Fiber (CF) material with a single color, plastic material with a single color, or the like. As a result, a rich change in color cannot be achieved, which results in poor user experience.
In view of this, there is a general solution in the related art that particular material is affixed to the outside of an electronic device, and when a user views at different angles of view, the material presents different colors in accordance with the optical interference principle.
That is, if the user wants to view a change in color of the appearance of the electronic device, the user must change the angle of view, which is inconvenient to achieve.
Thus, it is relatively complex to implement a change in color of the appearance of the electronic device in the related art.

As shown in
a main body 10 comprising a basic form and a deformed form; and
a color changing film 11 attached to the main body 10 to form a part of a surface of an appearance of the main body 10, the color changing film 11 being deformed with the main body 10 being changed from the basic form to the deformed form, wherein,
if the main body 10 is in the basic form, the color changing film 11 as the part of the appearance of the main body 10 presents a first visual effect; and
if the main body 10 is in the deformed form, the color changing film 11 as the part of the appearance of the main body 10 presents a second visual effect different from the first visual effect.
In the embodiment of the present disclosure, the main body 10 may be a flexible supporting housing of an electronic device having a flexible display screen, for example, a flexible housing on a back side of a mobile phone having a flexible screen. Alternatively, the main body 10 may also be a band for wearing an electronic device such as an smart wrist-mounted device, for example, a watchband of an smart watch, or a fixing band of an smart wristband. The main body 10 may also be a notebook computer, or a clamshell phone or the like, which is not limited in the present disclosure.
In the embodiment of the present disclosure, the basic form may be an appearance form of the electronic device when the electronic device is in a standby mode, and the corresponding deformed form may be a form of the electronic device when the electronic device is in an operation mode. Alternatively, the basic form may be an appearance form of the electronic device in a first operation mode, and the corresponding deformed form may be an appearance form of the electronic device in a second operation mode, or the like, which is not limited in the present disclosure.
For example, by taking the electronic device being a notebook computer as an example, the basic form may be a form when the notebook computer is not in use, for example, a form when the notebook computer is closed, and the corresponding deformed form may be a form when the notebook computer is in operation, for example, a form when the notebook computer is opened at a certain angle.
Alternatively, by taking a flexible smart mobile phone as an example, the basic form may be a form when the flexible mobile phone is not bent to deform, for example, an appearance form when the mobile phone is in an operation mode of a mobile phone, and the corresponding deformed form may be a form after the mobile phone is bent, for example, an appearance form when the mobile phone is bent to have a ring shape and the mobile phone is in an operation mode of an smart wristband.
Of course, those skilled in the art can obtain other embodiments within the protection scope of the present disclosure according to the above examples without contributing any creative effort, which will not be described in detail in the present disclosure.
In the embodiment of the present disclosure, the color changing film 11 may be used as the whole appearance of the main body 10. For example, the whole appearance of the flexible supporting housing of the flexible electronic device is set as the color changing film 11. Of course, in order to fix the color changing film 11 to the whole appearance of the flexible supporting housing, those skilled in the art may fix a perimeter of the color changing film 11 to the whole appearance of the flexible supporting housing in an affixing manner or another fixing manner, and remaining parts of the color changing film 11 may cover the whole appearance of the flexible supporting housing. When the flexible supporting housing is deformed, the whole color changing film correspondingly is deformed therewith, and a spacing between particles in the color changing film 11 change as the color changing film 11 is deformed. For example, when a spacing between particles is 2 nanometers, the color changing film 11 has a color of red, and when a spacing between particles is 3 nanometers, the color changing film 11 has a color of blue.
In the embodiment of the present disclosure, the color changing film 11 may be used as a part of the appearance of the main body 10, for example, an appearance of a rotational connecting member of a notebook computer. That is, the color changing film 11 may be attached to the appearance of the rotational connecting member. Of course, the attachment manner may be the same as that in the above example, or there may be another attachment manner, which is not limited in the present disclosure. When the color changing film 11 is deformed, for example, the notebook computer is controlled by opening at a certain angle to enter an operation state from an unused state, the color changing film 11 may deform with the rotational connecting member, and a spacing between particles in the color changing film 11 may also change correspondingly, so that a color of the color changing film 11 changes. The specific implementation thereof is the same as that in the above example, which will not be described in detail here.
In the embodiment of the present disclosure, a visual effect is a color effect of the color changing film. The visual effect may be single, for example, a single color, or may be diverse, for example, diverse colors or the like, which is not limited in the present disclosure.
Alternatively, in the embodiment of the present disclosure, the color changing film 11 is deformed with the main body 10 is changed from a basic form to a deformed form, so that the color changing film 11 is converted from a first visual effect to a second visual effect.
In the embodiment of the present disclosure, as the perimeter of the color changing film 11 is fixed to a region where the main body 10 is deformed, when the main body is deformed, the color changing film 11 may be subjected to an external stretching force or an external compressive force. Under the action of the external force, a spacing between a part of particles in the color changing film 11 may change therewith, which finally results in a change in color of the color changing film, thereby enhancing the visual effect of the electronic device.
Alternatively, in the embodiment of the present disclosure, the color changing film 11 is a one-piece film;
if the main body 10 is in the basic form, the one-piece film as the part of the appearance of the main body 10 has a first color, and the first visual effect is the first color; and
if the main body 10 is in the deformed form, the one-piece film as the part of the appearance of the main body 10 has a second color, and the second visual effect is the second color.
In the embodiment of the present disclosure, the color changing film 11 may be a one-piece film, i.e. a whole piece of film, rather than lamination or combination of multiple films. An advantage of using the one-piece film is that when the color changing film 11 is deformed with the main body 10, as the one-piece film has a relatively homogeneous overall construction and particles are disposed in alignment, when the color changing film is correspondingly deformed, a spacing between particles in the color changing film change in a relatively consistent manner, i.e., colors presented by the color changing film 11 are also more uniform. Further, as the manufacturing process of the one-piece film is relatively simple, in the process of producing and manufacturing a product, certain time which is spent on manufacturing may be saved, and some manufacturing steps may be omitted, which effectively improve the production efficiency of the product.
Alternatively, in the embodiment of the present disclosure, the color changing film 11 is comprised of M sub-films, where M is a positive integer greater than or equal to 2;
if the main body 10 is in the basic form, each of the M sub-films, as the part of the appearance of the main body 10, has a first color, at least a first sub-film of the M sub-films has a first color which is different from a first color of a second sub-film of the M sub-films, and the first visual effect is comprised of the first color of each of the M sub-films; and
if the main body 10 is in the deformed form, each of the M sub-films, as the part of the appearance of the main body 10, has a second color, at least the first sub-film of the M sub-films has a second color which is different from a second color of the second sub-film of the M sub-films, and the second visual effect is comprised of the second color of each of the M sub-films.
In the embodiment of the present disclosure, the color changing film 11 may also be comprised of multiple sub-films. As shown in
In the present embodiment of the present disclosure, in order to achieve richer visual experience, as shown in
In the present embodiment of the present disclosure, various sub-films may also be configured with the same initial color. That is, if the main body 10 is in a basic form, various sub-films are set to have a color of red. If the main body is deformed, various sub-films have the same degree of deformation. Therefore, If the main body 10 is in the deformed form, various sub-films have a color of blue. As the principle thereof is similar to that of the one-piece film, the description thereof will not be described in detail here. Of course, various sub-films may be set to have required colors by those skilled in the art by experience, which is also not limited in the present disclosure.
Alternatively, in the present embodiment of the present disclosure, the color changing film 11 is comprised of nanocrystals;
in the process of the color changing film being deformed as the main body 10 is changed from the basic form to the deformed form, a spacing between the nanocrystals in the color changing film change to achieve a visual effect of a change in color of the color changing film 11.
In the present embodiment of the present disclosure, the color changing film 11 is a nanocrystal film. When the film is subjected to an action such as stretching or extrusion which may actuate the film to deform, nanocrystals in the film are stretched or extruded therewith, and a spacing between the nanocrystals may decrease or increase. When the spacing decreases, the nanocrystals may mostly reflect or refract light close to a blue spectrum, while when the spacing increases, the nanocrystals may mostly reflect or refract light close to a red spectrum, which results in different colors being presented by the color changing film 11.
Alternatively, in the present embodiment of the present disclosure, the color changing film 11 may be a deformable colloid film.
In the present embodiment of the present disclosure, the color changing film 11 is an elastic deformable colloid film. Elasticity of the colloid film may be set to a suitable value by those skilled in the art by experience to ensure that the color changing film 11 can be used many times, thereby effectively improving the usage life of the whole electronic device.
Alternatively, in the present embodiment of the present disclosure, the color changing film 11 has a thickness within [0.1 mm, 0.5 mm].
In the present embodiment of the present disclosure, a value of the thickness of the color changing film 11 is merely a predetermined value which achieves a better effect. When the thickness is within the thickness range, the color changing film 11 can present a better visual effect. Further, the thickness range will not influence the hand feeling of the user. Of course, the thickness of the color changing film 11 may be adjusted to another value by those skilled in the art according to practical usage conditions, which is not limited in the present disclosure.
Alternatively, as shown in
a flexible supporting housing 12 having an accommodating cavity 13 formed therein and having an opening disposed therein;
a flexible display screen 14 disposed in the accommodating cavity 13 and having a display output region exposed through the opening;
a flexible circuit board 15 disposed in the accommodating cavity 13 and located between the flexible display screen 14 and the flexible supporting housing 12, wherein the flexible supporting housing 12, the flexible display screen 14 and the flexible circuit board 15 flexibly deform together under the action of an external force;
wherein the part of the surface of the appearance which is formed by attaching the color changing film 11 to the main body 10 is the whole appearance of the flexible supporting housing 12, or the part of the surface of the appearance which is formed by attaching the color changing film 11 to the main body 10 is the flexible supporting housing 12, and the flexible supporting housing 12 is made of the color changing film 11.
In the embodiment of the present disclosure, the flexible supporting housing 12 may be made of flexible glass material, flexible metal material, or flexible carbon fiber material, or the like. Alternatively, the color changing film 11 may be directly made into the flexible supporting housing 12, which is not limited in the present disclosure.
In the embodiment of the present disclosure, the flexible supporting housing 12 may have multiple stiffeners disposed therein, and there are gaps remaining between the stiffeners. Such design has an effect that when the flexible electronic device is not acted by an external force, the flexible electronic device may be maintained in a plate form, and when the flexible electronic device is bent, the stiffeners may further provide a certain amount of supporting force, to maintain a flexible form of the flexible electronic device. Further, as some gaps are reserved between various stiffeners, an angle at which the flexible supporting housing 12 may be bent is increased, thereby ensuring better scalability of the whole flexible electronic device.
In the embodiment of the present disclosure, when the flexible display screen 14 is bent to deform, the display performance of the flexible display screen 14 is not influenced by the deformation of the appearance thereof. Further, the flexible display screen 14 further has a function of implementing multi-screen display according to a degree of bending thereof. For example, when the flexible display screen 14 is bent at an angle greater than 90 degrees, the flexible display screen 14 may be divided into several sub-display screens according to perimeters which are formed after the screen is bent. These sub-display screens may display content independently, or may commonly display the same display content, which is not limited in the present disclosure.
In the embodiment of the present disclosure, the flexible circuit board 15 has a primary function of controlling the display content on the flexible display screen 14, responding to a user's operation or the like. The flexible circuit board 15 may deform under the action of an external force together with the flexible supporting housing 12 and the flexible display screen 14. Further, in order to ensure the function of the flexible circuit board 15 is not influenced after it is deformed, a flexibility process may be implemented on the flexible circuit board 15 by those skilled in the art according to practical conditions. The specific process thereof is also not described in detail in the present disclosure.
In the embodiment of the present disclosure, the main body 10 at least has two forms. The main body 10 may be in a basic form, which is a “plate” form. In this case, as shown in
In the embodiment of the present disclosure, the main body 10 may implement different functions by changing a form. By still taking the above example, the different functions may be for example a function of an smart mobile phone, a function of an smart wristband or the like. When the form is changed, the color changing film 11 may present a different visual effect according to the deformation. Then, the user may judge which operation mode the main body 10 is currently being according to the visual effect of the color changing film 11. For example, when the main body is in a plate form, i.e., the main body does not deform, the color changing film 11 has a color of yellow, and when the main body 10 is bent to deform, the color changing film 11 has a color changed to blue. Obviously, the electronic device according to the present disclosure has a function of well prompting the user of the operation mode in which the electronic device is currently being.

In this case, a basic form of the notebook computer is a closed form, and a deformed form of the notebook computer is a form when the notebook computer is in a usage mode, a presentation mode, a tent mode or the like, which is not limited in the present disclosure.
In the embodiment of the present disclosure, the color changing film 11 may be enclosed on the connecting member 18. Thereby, the connecting member 18 which is not convenient to be embellished relative to other portions of the notebook computer is enclosed as a whole, which largely improves the visual experience of the notebook computer.

In the embodiment of the present disclosure, the first housing layer 19 comprises two portions, for example, an opening for arranging a display screen and an opening for arranging a keyboard. The frame component arrangement layer 20 comprises multiple functional components of the electronic device, for example, a processor, a main board, a graphics card or the like. The second housing layer 21 may be a casing of the electronic device for enclosing related components of the frame component arrangement layer 20 together with the first housing layer 19. The first housing layer 19 and the second housing layer 21 are fixed by using an encapsulation technology.

a stretching apparatus 112 configured to actuate a change from the basic form to the deformed form; wherein,
if the color changing film 111 as the appearance of the main body 110 is in the basic form, the color changing film 111 presents a first visual effect; and
if the color changing film 111 as the appearance of the main body 110 is in the deformed form, the color changing film 111 presents a second visual effect different from the first visual effect.
In the embodiment of the present disclosure, the main body 110 may be a flexible supporting housing of a tablet computer, an electronic device having a flexible display screen or the like, for example, a flexible housing on a back side of a mobile phone having a flexible screen.

The stretching apparatus 112 has a function of actuating the color changing film 111 to deform, for example, stretching the color changing film 111. The stretching apparatus 112 may be controlled by the electronic device. Thus, the electronic device may control the color changing film 111 to present a particular visual effect through the stretching apparatus 112 according to users' requirements, which largely improves the user experience.
