Description

[0001] The invention relates to the field of electrical engineering and, in particular, to an electronic device. Currently, the external color of an electronic device is primarily determined by the color of the material from which the main body of the electronic device is made. For example, the main bodies of notebook computers can be made of single-color carbon fiber (CF) material, single-color plastic, etc. Impressive color changes are not possible, which reduces user satisfaction.

[0002] In the current state of the art, it is generally possible to apply a specific material to the outside of an electronic device that displays different colors under different viewing angles due to optical interference effects.

[0003] For a user to see the electronic device in a different color, they would have to change the viewing angle, which is unsatisfactory. Therefore, a color change in the appearance of an electronic device cannot be satisfactorily achieved with current technology.

[0011] According to one point of view, the present invention provides an electronic device comprising: a main body which can be transformed from a basic shape into a deformed shape, and a color-changing film attached to the main body which forms part of the externally visible surface of the main body and is deformed when the main body is transformed from the basic shape into the deformed shape, wherein the color-changing film exhibits a first visible effect as part of the external appearance of the main body when the main body is in the basic shape, and another, second visible effect as part of the external appearance of the main body when the main body is in the deformed shape.

[0015] Alternatively, it is envisaged that the color-changing film has nanocrystals and that, during the deformation of the color-changing film while the main body is deformed from the basic shape to the deformed shape, the distance between the nanocrystals changes in order to produce the visible effect as a color change of the color-changing film.

[0016] Alternatively, it is proposed that the color-changing film be a deformable colloidal film.

[0017] Alternatively, the color-changing film is intended to have a thickness in the range of 0.1 to 0.5 mm.

[0018] Alternatively, the main body is further provided to comprise: a flexible carrier housing with a receiving chamber formed therein and an opening arranged therein, a flexible screen arranged in the receiving chamber and having a display area visible through the opening, and a flexible circuit board arranged in the receiving chamber and located between the flexible screen and the flexible carrier housing, wherein the flexible carrier housing, the flexible screen and the flexible circuit board deform flexibly together under an external force, wherein a part of the externally visible surface formed by the application of the color-changing film to the main body is the entire externally visible area of ​​the flexible carrier housing, or the part of the external appearance of the main body formed by the applied color-changing film is the flexible carrier housing, and the flexible carrier housing is made of the color-changing film.

[0019] Alternatively, the main body is provided to further comprise: a first part, a second part, a connecting element that connects the first part to the second part, wherein a displacement of the first part relative to the second part is effected by means of the connecting element, wherein a part of the externally visible surface, which forms the color-changing film attached to the main body, is the connecting element covering the main body.

[0020] Alternatively, the main body is provided to further comprise: a first housing layer, a component receiving frame layer and a second housing layer, wherein the component receiving frame layer is encapsulated by the first and the second housing layers and lies in an inner encapsulated space formed by the first housing layer and the second housing layer, wherein the component receiving frame layer comprises: a first frame, a pivot connecting element and a second frame pivotably connected to the first frame by the pivot connecting element, wherein the first frame and the second frame are deformed by the pivot connecting element under the application of a force.

[0021] According to another aspect of the inventive concept, the invention provides for an electronic device which in particular comprises: a main body, a color-changing film attached to the main body which has a basic shape and a deformed shape, and a stretching device which is configured to effect a change from the basic shape to the deformed shape, wherein the color-changing film, when it is in the basic shape as an external appearance of the main body, shows a first visible effect and, when it is in the deformed shape, shows another, second visible effect.

[0022] The technical solutions according to the embodiments of the invention have at least the following technical effects and advantages.

[0023] In embodiments of the invention, the technical means is used to attach a color-changing film to a part of the outer surface of the main body, so that with a change in the shape of the main body the color-changing film also deforms, making different optical effects visible in order to increase user satisfaction.

[0024] In embodiments of the invention, if the main body is of different shapes, the color-changing film can have different colors. This allows the user to recognize the state of the electronic device simply by the color of the color-changing film, thus immediately ascertaining the current operating state of the electronic device and simultaneously improving its visual appearance.

[0025] To explain the invention, it is described below with reference to the drawings in the form of exemplary embodiments. Naturally, the drawings serve only to illustrate exemplary embodiments, and a person skilled in the art can easily deduce deviations from the invention and any further graphical explanations from the following.

[0026] The drawings show: Fig. 1. A representation of an electronic device according to an embodiment of the invention, Fig. 2 a block representation of a color change according to an embodiment of the invention, Fig. 3A - 3B Block representations of a color-changing film according to an embodiment of the invention, Fig. 4A - 4C Illustrations of an electronic device according to a further embodiment of the invention, Fig. 5A - 5B Illustrations of an electronic device of a further embodiment of the invention, Fig. 6A - 6B Illustrations of an electronic device of a further embodiment of the invention and Fig. 7 a schematic representation of an electronic device according to a further embodiment of the invention.

[0027] The embodiments of the invention provide an electronic device comprising: a main body which can be transformed from a basic shape into a deformed shape, and a color-changing film attached to the main body which forms part of the externally visible surface of the main body and is deformed when the main body is transformed from the basic shape into the deformed shape, wherein the color-changing film exhibits a first visible effect as part of the external appearance of the main body when the main body is in the basic shape, and another second visible effect as part of the external appearance of the main body when the main body is in the deformed shape.

[0028] In embodiments of the invention, the technical means is used to attach a color-changing film to a part of the outer surface of the main body, so that with a change in the shape of the main body the color-changing film also deforms, making different optical effects visible in order to increase user satisfaction.

[0029] In embodiments of the invention, if the main body is of different shapes, the color-changing film can have different colors. This allows the user to recognize the state of the electronic device simply by the color of the color-changing film, thus immediately ascertaining the current operating state of the electronic device and simultaneously improving its visual appearance.

[0030] To illustrate and facilitate understanding of the invention, it is described below with reference to the drawings in the form of exemplary embodiments. Naturally, the drawings serve only to explain exemplary embodiments, and a person skilled in the art can easily deduce deviations from the invention and any further graphic representations from the following descriptions. Further embodiments are obvious to a person skilled in the art within the scope of the disclosure of the present invention, without requiring any inventive step. Furthermore, features from the embodiments of the invention can be freely combined with one another.

[0031] Where the term “and / or” is used here, it is intended to encompass both an interpretation as “and” and an interpretation as “or”.

[0032] Fig. Figure 1 shows an electronic device according to one embodiment of the present invention, which comprises: a main body 10, which can be transformed from a basic form into a deformed form, and a color-changing film 11 attached to the main body 10, which forms part of the externally visible surface of the main body 10 and is deformed when the main body 10 is moved from the basic shape to the deformed shape, wherein the color-changing film 11, as part of the external appearance of the main body 10, shows a first visible effect when the main body 10 is in its basic form, and the color-changing film 11, as part of the external appearance of the main body 10, shows another, second visible effect when the main body 10 is in its deformed form.

[0033] In this embodiment, the main body 10 can be a flexible carrier housing of an electronic device that has a flexible screen, for example, a flexible main body on the back of a mobile phone with a flexible screen. Alternatively, the main body 10 can also be a band for wearing an electronic device, for example, a smart wrist device, a watch strap for a smartwatch, or a fastening strap for a smart device worn on the arm. The system can also be part of a notebook computer, a telephone, etc. There are no restrictions in this regard.

[0034] In this embodiment, the basic form can be the appearance of the electronic device when it is in standby mode. The deformed form can be the form of the electronic device when it is in an operating state. Alternatively, the basic form can be the appearance of the electronic device during a first operating state, and the deformed form during a second operating state. There are no restrictions in this regard.

[0035] For example, if we consider a notebook as an electronic device, the basic form can be that when the notebook computer is not in use, for example when folded, and the deformed form can be the form when the notebook computer is in operation, i.e. when it is opened to a certain angle.

[0036] Alternatively, taking a flexible smartphone as an example, the basic form can be that when the flexible smartphone is not deformed, for example when it is in operating mode as a mobile phone, and the deformed form is that when the mobile phone is bent, for example a state in which it is bent into a ring and can be worn as a smart bracelet.

[0037] Of course, a person skilled in the art could easily devise other embodiments of the invention as variations of the examples above. Such further variations are therefore not described in detail here.

[0038] In this embodiment of the invention, the color-changing film 11 can comprise the entire outer surface of the main body 10. For example, the entire outer surface of the flexible carrier housing of the flexible electronic device is formed by the color-changing film 11. To attach the color-changing film 11 to the entire outer surface of the flexible carrier housing, a person skilled in the art can define an edge of the color-changing film 11 such that it can be attached to the outer surface of the flexible carrier housing, so that the color-changing film 11 covers the entire outer surface of the flexible carrier housing. If the flexible carrier housing is deformed, the entire color-changing film also deforms, and the distance between particles in the color-changing film 11 changes with the deformation of the color-changing film 11.For example, if the distance between particles is 2 nm and the color-changing film 11 is red, the color-changing film 11 can be blue if the distance between the particles is 3 nm.

[0039] In this embodiment of the invention, the color-changing film can also be provided for only a portion of the outer surface of the main body 10, for example, the outer surface of a swivel connector of a notebook computer. The color-changing film 11 is then attached to the outer surface of the swivel connector. This can be the attachment method mentioned above; other attachment options are, of course, possible. If the color-changing film 11 is deformed, for example, because the notebook computer is opened to a specific angle for use, the color-changing film 11 deforms along with the swivel connector, thereby changing the distance between particles in the color-changing film 11 and thus its color. The specific embodiment corresponds to the one mentioned above and will not be explained again here.

[0040] In the embodiment of the present invention, a visible effect is a color effect of the color-changing film. It can be a single visible effect, for example, a single color, or several visible effects, for example, different colors. There is no limitation in this respect.

[0041] Alternatively, in the embodiments of the invention, it is provided that the color-changing film 11 is deformed from the basic shape to the deformed shape when the main body 10 is changed, so that it changes from the first visible effect to the second visible effect.

[0042] In this embodiment of the present invention, since the edge of the color-changing film 11 is attached to a region of the main body 10 that deforms when the main body 10 is deformed, the color-changing film 11 is stretched or compressed under an external force. This can change the distance between particles in the color-changing film 11, resulting in a color change of the color-changing film and thus an improvement in the optical appearance and function of the electronic device.

[0043] In non-inventive embodiments, it is provided that the color-changing film 11 is a one-piece film and that the one-piece film has a first color as part of the external appearance of the main body 10 when the main body 10 is in its basic form, so that the first visible effect is the first color, and that the one-piece film has a second color as part of the external appearance of the main body when the main body 10 is in its deformed form, so that the second visible effect is the second color.

[0044] In this non-inventive embodiment, the color-changing film 11 is a single, one-piece film instead of a laminated structure or a combination of several films, which would be equally possible. The advantage of a one-piece film is that, when the color-changing film 11 is deformed together with the main body 10, it has a relatively more homogeneous structure. This results, for example, in a relatively uniform displacement of the particles in the color-changing film when the film is deformed; that is, the color effect exhibited by the color-changing film 11 is more uniform. Furthermore, manufacturing a one-piece film is comparatively simple, thus saving manufacturing time and production steps, which promotes production efficiency.

[0045] In one embodiment of the present invention, the color-changing film 11 comprises at least M sub-films, wherein M is an integer ≤ 2, each of the M sub-films having a first color as part of the external appearance of the main body 10 when the main body 10 is in its basic form, wherein at least one first sub-film of the M sub-films has a first color that differs from that of a second sub-film, so that the first visible effect comprises the first colors of the M sub-films, and each of the M sub-films having a second color as part of the external appearance of the main body 10 when the main body 10 is in its deformed form, wherein the first sub-film of the M sub-films has a second color that differs from that of the second sub-film of the M sub-films, so that the second visible effect comprises the second colors of the M sub-films.

[0046] In the embodiment of the present invention, the color-changing film 11 can be composed of several partial films. How Fig. Figure 2 shows that the color-changing film is formed by "stacking" several sub-films. The term "stacking" can refer to the fact that the multiple color films are placed on top of each other or next to each other, in order to influence the deformation of the multiple sub-films collectively or to influence the deformation of individual sub-films. The sub-films can therefore also lie side by side. Furthermore, the sub-films can have different shapes. For example, one sub-film can be rectangular, another square, etc. There are no restrictions in this regard.

[0047] In order to achieve a particularly diverse optical impression, one can, in the embodiment of the present invention according to Fig. 3A and Fig. 3B Use different sub-films with different colors, for example, viewed from left to right and from top to bottom, the sequence red, orange, yellow, green, blue, and white. If the main body 10 is deformed, several sub-films undergo the same deformation. If several sub-films have several different initial colors, the sub-films do not behave the same way when the main body 10 is moved from its basic shape to its deformed shape. In the example shown, the six sub-films then assume the colors yellow, blue, green, white, red, and orange, viewed from left to right and top to bottom, respectively. Thus, the color-changing film 11 is also multicolored from the six sub-films before the main body is deformed. After its deformation, the color-changing film 11 remains multicolored, with the color of each sub-film changing. As a result, the main body exhibits a diverse color effect and can meet the user's requirements.

[0048] In the embodiment of the present invention, several partial films can also be designed to initially have the same color. For example, several partial films are red when the main body 10 is in its basic shape. If the main body 10 is deformed, the several partial films undergo the same deformation. They then all have, for example, the color blue when the main body 10 is in the deformed state. This results in conditions similar to those of a single-piece film, which is why the description in this respect is not repeated. Of course, several partial films can be designed by a person skilled in the art to have any desired color. There is no limitation in this regard.

[0049] Alternatively, in the embodiment of the present invention, it can be provided that the color-changing film 11 has nanocrystals and that, when the color-changing film 11 is deformed together with the deformation of the main body 10 from the basic shape to the deformed shape, a distance between the nanocrystals changes in order to produce the visible effect as a color change of the color-changing film.

[0050] In this embodiment of the invention, the color-changing film 11 is a nanocrystal film. When it is actuated, for example by stretching or compressing, and the film is thereby deformed, the nanocrystals are also stretched or compressed, and the distance between the nanocrystals increases or decreases. If the distance decreases, the nanocrystals reflect or backscatter light more in the blue range, whereas if the distance increases, the nanocrystals reflect or backscatter light more in the red spectral range, so that the color-changing film 11 displays different colors.

[0051] Alternatively, in this embodiment it is provided that the color-changing film 11 can be a deformable colloidal film.

[0052] In this embodiment, the color-changing film 11 is an elastically deformable colloidal film. A person skilled in the art can suitably provide the elasticity of the colloidal film to ensure that the color-changing film 11 can be used very frequently, thus increasing the service life of the electronic device.

[0053] Alternatively, in this embodiment of the invention, it is provided that the color-changing film 11 has a thickness in the range between 0.1 and 0.5 mm.

[0054] In this embodiment of the invention, the thickness of the color-changing film 11 is selected to achieve a particularly good effect. If the thickness is within the specified range, the color-changing film 11 exhibits a particularly good visible effect. Furthermore, the thickness within the specified range does not affect the tactile feel. Of course, a different value for the thickness of the color-changing film 11 can also be chosen, depending on the specific requirements. There are no restrictions in this regard.

[0055] Alternatively, as in Fig. As shown in 4A, an embodiment of the invention further comprises the main body 10: a flexible carrier housing 12 with a receiving chamber 13 formed therein and an opening arranged therein, a flexible screen 14, which is arranged in the recording recess and has a display area visible through the opening, and a flexible circuit board 15 arranged in the receiving chamber 13, which lies between the flexible screen 14 and the flexible carrier housing 12, wherein the flexible carrier housing 12, the flexible screen 14 and the flexible circuit board 15 deform flexibly together under an external force, wherein a part of the outer surface, which is formed by the color-changing film attached to the main body 10, is the entire externally visible area of ​​the flexible carrier housing 12, or the part of the outer appearance of the main body 10 formed by the attached color-changing film 11 is the flexible carrier housing 12, and the flexible carrier housing 12 is made of the color-changing film 11

[0056] In this embodiment, the flexible carrier housing 12 can be made of a flexible glass material, a flexible metal, a flexible carbon fiber material, etc. Alternatively, the color-changing film 11 can be incorporated directly into the flexible carrier housing 12. There are no restrictions in this regard.

[0057] In this embodiment, several reinforcements can be arranged in the flexible carrier housing 12, with gaps remaining between the reinforcements. Such a design has the advantage that the flexible electronic device maintains a flat configuration as long as no external force is applied. When the flexible electronic device is bent, the reinforcements provide the main body with a certain degree of rigidity to maintain the flexible shape of the device. The gaps left between the various reinforcements increase the angle through which the flexible carrier housing 12 can be bent, thereby improving the overall adaptability of the flexible electronic device.

[0058] In this embodiment of the invention, if the flexible screen 14 is bent into a deformation, its display performance is not affected. Furthermore, the flexible screen 14 optionally has the function of displaying multiple messages depending on the degree of bending. For example, if the flexible screen 14 is bent at an angle greater than 90 degrees, it is divided into several sub-displays according to the circumference formed by the bending of the screen. These sub-displays can independently display content or jointly display the same content. There are no restrictions in this regard.

[0059] In this embodiment of the invention, the flexible circuit board 15 has the main function of controlling the displayed content on the flexible screen 14 according to user input, etc. Under a force, the flexible circuit board 15 deforms together with the flexible support housing 12 and the flexible screen 14. To ensure that the function of the flexible circuit board 15 is not impaired by the deformation, a person skilled in the art can provide the flexibility of the flexible circuit board 15 appropriately according to current requirements. This will not be explained in detail here.

[0060] In this embodiment, the main body 10 essentially has two shapes. The main body 10 can be in a basic shape, which is a "planar" shape. In this case, which is in Fig. As shown in Figure 4B, the main body 10 can be that of a smartphone with a flexible screen and possess the necessary functionality for a smartphone. Due to the reinforcements, the main body 10 remains in a flat shape as long as no external force is applied. Furthermore, as shown in Figure 4B, the main body 10 can be... Fig. As shown in Figure 4C, the main body 10 can also be in a deformed form, for example, bent into a bracelet shape. In this case, the main body 10 is that of a smart bracelet with a flexible screen. The screen in its originally flat state also serves as a screen for the smart bracelet. When the electronic device is in this state, the corresponding functions of a smart bracelet can be realized. Of course, the main body 10 can be bent into a smart bracelet shape in various ways. For example, the main body 10 can be bent inwards along a line that is perpendicular to the long side of the flexible screen 14 and runs along its midpoint, so that the flexible screen 14 forms the inside of the smart bracelet. Alternatively, the main body 10 can also be bent outwards along the aforementioned line, so that the flexible screen 14 serves as the screen for the smart bracelet.There are no restrictions in this regard.

[0061] In this embodiment of the invention, the main body 10 can perform various different functions through deformation. In the example above, these different functions could be those of a smartphone or a smart bracelet, etc. When the shape of the device is changed, the color-changing film 11 displays a different visible effect corresponding to the deformation. The user recognizes the current operating state of the main body 10 based on the visible effect of the color-changing film 11. For example, if the main body is in a flat shape, i.e., not deformed, the color-changing film 11 can be yellow, and blue when the main body 10 is bent. The electronic device according to the invention thus clearly indicates its current operating state to the user.

[0062] Alternatively, how Fig. Figure 5A shows that in one embodiment of the invention, the main body 10 further comprises: a first part 16, a second part 17, a connecting element 18 that connects the first part 16 to the second part 17, wherein a deformation of the first part 16 relative to the second part 17 takes place by means of the connecting element 18, wherein part of the externally visible surface, which forms the color-changing film 11 attached to the main body 10, is the connecting element 18 covering the main body 10.

[0063] In this embodiment, if the electronic device is, for example, a notebook computer, then the first part 16 is, for example, a part with a screen, the second part 17 is a part with a keyboard, and the connecting element 18 is a swivel mechanism or hinge of the notebook computer that connects the two parts. Then the basic state of the notebook computer is the folded state, and the deformed state is a usage state, a presentation state, a V-shaped setup state, etc. There are no restrictions in this regard.

[0064] In this embodiment of the invention, the color-changing film can be enclosed on the connecting element 18. Since it is not advantageous for the connecting element 18 to be conspicuous compared to the other parts of the notebook computer, the connecting element 18 is completely enclosed, thereby improving the visual appearance of the computer.

[0065] Alternatively, as in Fig. As shown in Figure 5B, in the embodiment of the present invention, the first part 16 comprises a screen, a processor, etc., and the second part 17 is a carrier for the electronic device, which is arranged on the connecting element 18. The connecting element 18 is located on one side of the first part 16. When the electronic device is in its initial state, the carrier can be pivoted so that it is in the same plane as the first part. In this way, the user does not perceive the carrier, thus increasing user satisfaction. The color-changing film 11 is enclosed on a surface of the carrier and further enclosed in a portion of an area of ​​the first part 16, such that the color-changing film 11 covers a gap between the carrier and the first part 16, thereby improving the overall visual appearance of the electronic device.If the carrier is pulled away from the plane in which the first part is located, the color-changing film 11 is stretched and deformed, resulting in a different optical effect.

[0066] Alternatively, how Fig. Figure 6A shows, as provided in an embodiment of the invention, that the main body 10 further comprises: a first case layer 19, a component mounting frame layer 20 and a second housing layer 21, wherein the component receiving frame layer 20 is encapsulated by the first 19 and the second housing layer 21 and is located in an inner encapsulated space formed by the first housing layer 19 and the second housing layer 21, wherein the component receiving frame layer 20 has: a first frame, a swivel connecting element and a second frame 24 pivotably connected to the first frame 22 by the pivot connecting element 23, wherein a deformation of the first frame 22 and the second frame 24 is achieved by the pivot connecting element 23 by applying a force.

[0067] In this embodiment of the invention, the first housing layer 19 (also housing top) has two areas, for example, an opening for a screen and an opening for a keyboard. The component mounting frame layer 20 (also housing middle) comprises several functional components of the electronic device, for example, a processor, a motherboard, a graphics card, etc. The second housing layer 21 (also housing bottom) together with the first housing layer 19 forms a housing for the electronic device, which accommodates the components of the component mounting frame layer 20. The first housing layer 19 and the second housing layer 20 are connected by means of an encapsulation technique.

[0068] Alternatively, as in Fig. As shown in Figure 6B, in the embodiment of the invention, the pivoting connecting element 23 is visible; that is, an opening provided in the second housing layer 21 exposes the pivoting connecting element 23. The color-changing film 11 is then visible at the visible pivoting connecting element 23. When the pivoting connecting element 23 is pivoted, the color-changing film deforms, thereby changing its optical effect and revealing a different color. Of course, the pivoting connecting element 23 can also be encapsulated directly in the first housing layer 19 and the second housing layer 20. In this case, the color-changing film can be arranged on the outside of the second main body 21. A person skilled in the art can design this appropriately. There are no limitations in this regard.
