A cover plate assembly and an electronic device provided according to an embodiment of the present application are described below with reference to fig. 1 to 11.
As shown in fig. 1, one embodiment of the present application provides a cover plate assembly 100, including: a cover body 102; a liquid droplet layer 104 and an electrode layer 106 which are stacked and provided on one side of the cover 102, the electrode layer 106 being provided on the side of the liquid droplet layer 104 away from the cover 102; the liquid drop layer is provided with a plurality of liquid drops, the electrode layer is provided with a plurality of electrodes, the plurality of liquid drops correspond to the plurality of electrodes one to one, and the electrodes are used for adjusting the shapes of the corresponding liquid drops.
Embodiments of a cover plate assembly 100 provided according to the present application, including a cover 102, a droplet layer 104 and an electrode layer 106, by providing a stack of droplet layer 104 and electrode layer 106 on one side of cover 102, a voltage may be applied to the droplets 1042 in the droplet layer 104 by the electrode layer 106, under the action of the voltage change, the shape of the corresponding part of the liquid drop 1042 in the liquid drop layer 104 will change, the cover plate assembly 100 as a whole may thus achieve different patterns or dynamic effects that greatly enhance the display functionality of the cover plate assembly 100, e.g., by controlling the voltages of the various electrodes 1062, can display information such as real-time, weather and the like when a user has functional requirements, greatly expands the display mode of the information acquired by the user, when the user has a display requirement, the displayed interface pattern can be defined by user, and the use experience of the user is improved.
The droplet layer 104 and the electrode layer 106 need to be stacked, so that the electrode layer 106 can more easily form an electric field covering the droplet layer 104, and the shape of the droplet 1042 in the droplet layer 104 of the corresponding portion can be changed by subsequently adjusting the voltage of the electrode 1062 in the electrode layer 106, thereby enhancing the overall display functionality. Specifically, the plurality of droplets 1042 are disposed in the droplet layer 104, the plurality of electrodes 1062 are disposed on the electrode layer 106, and the droplets 1042 and the electrodes 1062 are in one-to-one correspondence, so that the shapes of the droplets 1042 at the corresponding positions can be adjusted under the action of the electrodes 1062, and the cover plate assembly 100 can display different patterns or different dynamic effects in a macroscopic view under the combined action of the deformation of the plurality of droplets 1042.
As shown in fig. 8, a particular number, e.g., 2021, can be formed by moving a droplet 1042.
Alternatively, as shown in FIG. 9, special dynamic effects can be created by moving the droplets 1042, for example by switching from a rectangular array to a circumferential array, with circumferential movement occurring.
It is understood that the droplet layer is a hollow shell, and a large number of droplet particles are present inside, and the arrangement of the droplet particles is dense, but a certain gap needs to be reserved between the droplets 1042 to facilitate the change and movement of the shape, and the specific arrangement is not limited. To ensure that the droplet 1042 at each position can be influenced by one electrode 1062 to deform accordingly.
The shape of the electrode layer 106 may be as shown in fig. 6 and 7, specifically, as shown in fig. 6, the electrode layer 106 is rectangular, and the electrodes 1062 are formed to intersect in a rectangular shape, or as shown in fig. 7, the electrode layer 106 is annular, and each electrode 1062 is circular.
Further, for a single electrode 1062 and the corresponding portion of the droplet 1042, the adjustment of the voltage can make the shape of the droplet 1042 change, thereby showing a dynamic effect. When the electrode 1062 is turned on, the applied voltage changes the contact angle to attract the water droplet and stretch the edge of the water droplet to be flat, then the electrode 1062 is gradually turned off, the adjacent electrode 1062 is gradually turned on, one path of continuous switch is continuously pulled, and the liquid droplet 1042 rolls along the direction of turning on the electrode 1062, so that a dynamic effect is presented.
For the droplet layer 104, a plurality of droplets 1042 are disposed in the droplet layer 104, and a certain gap needs to be formed between the plurality of droplets 1042, so that the droplets 1042 can change and move in shape, and avoid interference.
Note that, as shown in fig. 2 and 3, the degree of wetting of the liquid drop 1042 with the solid surface is generally defined by the contact angle. The surface solid surface is more hydrophobic when the contact angle is larger. The smaller the contact angle, the more hydrophilic the surface solid surface. If a large array of electrodes 1062 is present on the solid surface, the contact angle can be adjusted by voltage, forcing the shape of the droplet 1042 to change.
Further, the cover 102 includes: a cover plate 1022, wherein a light-transmitting area 1023 is arranged on the cover plate 1022; the diaphragm 1024 is arranged on one side, close to the droplet layer 104, of the cover plate 1022, and a hollow portion 1025 is arranged on the diaphragm 1024, wherein the hollow portion 1025 is arranged opposite to the light-transmitting region 1023; wherein, the projection of the droplet layer 104 on the cover plate 1022 covers the light-transmitting area 1023.
The cover 102 mainly includes a cover plate 1022 and a membrane 1024, the cover plate 1022 serves as an outer casing of the entire cover assembly 100 and can protect the membrane 1024, the droplet layer 104 and the electrode layer 106 inside, and the membrane 1024 is used to seal the cover plate 1022 with a middle frame or other fixed structure so as to prevent dust. It can be understood that the whole of the membrane 1024 is opaque, in order to ensure that the variation of the inner droplet layer 104 can be normally displayed outward through the cover plate 1022, a hollow part 1025 needs to be formed in the membrane 1024, and meanwhile, a transparent area 1023 with certain transparency is formed at a relative position on the cover plate 1022, on this basis, the transparent area 1023 can be covered by limiting the projection of the droplet layer 104 on the cover plate 1022, so that the effect displayed by the droplet layer 104 can be displayed outward under the condition that different voltages are applied to the droplet layer 104 by the electrode layer 106.
Further, as shown in fig. 4 and 5, the spacing between any two adjacent droplets in the droplet layer is equal.
The same distance exists between the liquid drops in the liquid drop layer, so that the corresponding arrangement of the electrodes is facilitated on one hand, and meanwhile, the liquid drops are uniformly arranged in the liquid drop layer, so that the display change of different dynamic effects and patterns is facilitated.
In one embodiment, the droplets 1042 are in a matrix array as shown in FIG. 4 and the droplet layer 104 is rectangular, and in another embodiment, the droplet layer 104 is circular as shown in FIG. 5.
Further, the arrangement between the plurality of liquids is not limited.
Further, still include: and the control circuit board 108 and the electrode layer are arranged on the same side of the cover body, the control circuit board 108 is electrically connected with the electrode layer 106, and the control circuit board 108 is used for controlling the voltage of each electrode 1062.
By providing the control circuit board 108 electrically connected to the electrode layer 106, the voltage of each electrode 1062 can be individually controlled, so as to display the local or overall dynamic appearance effect. The electrical connection between the control circuit board 108 and the electrode layer 106 may be a wired connection or a connection via wireless communication.
It should be noted that the control circuit board 108 and the electrode layer are disposed on the same side of the cover, so that on one hand, the control circuit board 108 is covered by the cover, thereby reducing the possibility of exposure, and on the other hand, the length of the electrical connection between the control circuit board 108 and the electrode layer is reduced, thereby reducing a certain control delay.
The control circuit board 108 includes, but is not limited to, a single panel, a double-sided board, and a multi-layer circuit board.
Further, still include: and a connector 110, wherein one end of the connector 110 is connected with the control circuit board 108, and the other end is connected with the electrode layer 106.
Through setting up connector 110 to link to each other with control circuit board 108 and electrode layer 106 respectively with the both ends of connector 110, can realize the electric connection of control circuit board 108 between electrode layer 106 under the effect of connector 110, thereby can promote the firm degree of electric connection, also be favorable to promoting the interference killing feature of connection.
Further, as shown in fig. 10, the method further includes: the moving element 112 is connected to the electrode layer 106, the moving element 112 is disposed on a side of the electrode layer 106 away from the droplet layer 104, and the moving element 112 can move to drive the electrode layer 106 and the droplet layer 104 to move relatively.
Through setting up the moving member 112 that links to each other with electrode layer 106, can drive to take place relative movement between electrode layer 106 and the liquid droplet layer 104 under the removal effect of moving member 112 self, specifically speaking, because liquid droplet layer 104 is the main part that mainly shows dynamic effect, so only need link to each other moving member 112 and electrode layer 106 to drive electrode layer 106 and take place to remove, can realize the drive to the different parts of liquid droplet layer 104, can further improve the variety of change.
For the embodiment of controlling the movement of the electrode layer 106, the circuit control board can selectively control the voltage of the electrode 1062 as a whole, or selectively control the voltage of a part of the electrode 1062, so as to realize the movement variation of a large area.
Further, still include: magnetic element 1122 and electromagnet 1124; the moving part 112 is provided with a magnetic part 1122, the electromagnet 1124 is arranged opposite to the magnetic part 1122, and the electromagnet 1124 is used for driving the magnetic part 1122 to drive the moving part 112 to move when being electrified; or the moving part 112 is provided with an electromagnet 1124, the magnetic element 1122 is arranged opposite to the electromagnet 1124, and the electromagnet 1124 is used for driving the moving part 112 to move under the action of the magnetic element 1122 when being powered on.
In order to ensure the movement of the moving member 112, the magnetic member 1122 and the electromagnet 1124 are provided, and in a specific embodiment, the magnetic member 1122 is provided on the moving member 112, and the electromagnet 1124 is relatively provided at the position of the magnetic member 1122, so that the magnetic member 1122 can be directly driven to move when the electromagnet 1124 is powered on, and the moving member 112 can be moved because the magnetic member 1122 is provided on the moving member 112. In another specific embodiment, an electromagnet 1124 is disposed on the moving member 112, and the magnetic member 1122 is disposed at a position opposite to the electromagnet 1124, so that when the electromagnet 1124 is energized, magnetic force is applied to the magnetic member 1122, and under the action of a magnetic field generated by the magnetic member 1122, the electromagnet 1124 is moved, thereby moving the moving member 112.
Further, the electromagnet 1124 is energized to generate a repulsive force to the magnetic member 1122, and the cover plate assembly 100 further includes: the buffer 114 is disposed on one side of the moving member 112, wherein the buffer 114 and the electromagnet 1124 are disposed on both sides of the moving member 112 when the magnetic member 1122 is disposed on the moving member 112, or the buffer 114 and the magnetic member 1122 are disposed on both sides of the moving member when the electromagnet 1124 is disposed on the moving member 112.
When the electromagnet 1124 is limited to be energized, a repulsive force is generated, so that the magnetic member 1122 and the electromagnet 1124 can be driven to move in opposite directions, and in order to reduce the possibility that the magnetic member 1122 interferes with other structures in the cover plate assembly 100 to cause damage when moving, a buffer member 114 is further provided, and the buffer member 114 is arranged on one side of the moving member 112, so that buffering is realized. Specifically, when the magnetic element 1122 is disposed on the moving element 112, the buffering element 114 and the electromagnet 1124 are distributed on two sides of the moving element 112 in the moving direction, and when the electromagnet 1124 is disposed on the moving element 112, the buffering element 114 and the magnetic element 1122 are distributed on two sides of the moving element 112 in the moving direction, so as to ensure that the buffering effect can be achieved.
In one particular embodiment, a back cover structure is provided by adhering the diaphragm 1024 to the back cover (i.e., cover 102) and then to the bezel, as in a conventional cell phone structure. The open area (i.e. the hollow 1025) of the patch 1024 corresponds to the transparent area (i.e. the light-transmitting area 1023) of the back cover, and a special structure is added below the transparent area, including the array electrode layer 106 and the droplet layer 104, wherein the size of the array electrode layer 106 and the droplet layer 104 is larger than that of the open area of the patch 1024. The array electrode layer 106 is communicated with the mobile phone motherboard PCB through the connector 110, that is, the mobile phone motherboard PCB can control the voltage and state of each electrode 1062 of the array electrode layer 106, so as to control each liquid drop 1042. The droplet layer 104 is a hollow shell, a large number of droplet particles are encapsulated in the hollow shell and distributed on the lower surface of the shell, and the droplet layer 104 plays a role in protecting the droplets 1042.
It is to be noted that the degree of wetting of the liquid drop 1042 with the solid surface is generally defined by the contact angle. The surface solid surface is more hydrophobic when the contact angle is larger. The smaller the contact angle, the more hydrophilic the surface solid surface. If a large array of electrodes 1062 is present on the solid surface, the shape of the droplet 1042 is forced to change by adjusting the contact angle with a voltage. For a single electrode 1062 and the corresponding droplet 1042, the adjustment of the voltage can make the shape of the droplet 1042 change, thereby showing a dynamic effect. When the electrode 1062 is turned on, the applied voltage changes the contact angle to attract the water droplet and stretch the edge of the water droplet to be flat, then the electrode 1062 is gradually turned off, the adjacent electrode 1062 is gradually turned on, one path of continuous switch is continuously pulled, and the liquid droplet 1042 rolls along the direction of turning on the electrode 1062, so that a dynamic effect is presented.
Further, each of the droplets 1042 of the droplet layer 104 is arranged in a certain manner, and a reasonable gap is left between the droplets 1042, so that the shape of the liquid can be changed and moved conveniently, and interference can be avoided. The arrangement is not limited, and the array electrode layer 106 under the droplet layer 104 achieves independent control of each droplet 1042 through pressurization. The color of the droplets 1042 can be customized, for example, black, white, colored, and the like.
As shown in fig. 6 and 7, the electrodes 1062 are in communication with the PCB, and each electrode 1062 can be independently controlled to control the shape and position of each droplet 1042 thereon.
In one embodiment, as shown in FIG. 8, the original arrangement of droplets 1042 is on the left, and the movement of each droplet 1042 is independently and sequentially controlled by logic voltages applied to the lower array electrode 1062 to form a date or time pattern 2021 or 20:21, which is visible to the human eye through the transparent region of the back cover.
In another embodiment, as shown in fig. 9, the original arrangement of droplets 1042 is shown on the left, and the movement of each droplet 1042 is independently and sequentially controlled by the logic voltage of the lower array electrode 1062, so that the droplets 1042 rotate in a certain direction, and the human eye can see the rotating pattern through the transparent region of the back cover.
In one particular embodiment, another back cover configuration is provided, differing from the previous one in that the entire display electrode layer 106 is moved in its entirety in addition to the independent on-control of each electrode 1062. The PCB supplies power to the electromagnet 1124 via the connector 110, and when energized, the electromagnet 1124 repels the armature, pushing the armature to move left, and the array electrode layer 106 is mounted to the armature, moving left with the armature. In order to prevent the armature from moving too fast, a spring and a fixed column are arranged on the left side of the armature for buffering. During the time that the current to the electromagnet 1124 is reduced until power is removed, the spring will urge the armature to move to the right, and the array electrode layer 106 will fit onto the armature and move to the right with the armature. The electrode 1062 can adjust the contact angle of the droplet 1042 by voltage, so as to force the shape of the droplet 1042 to change, i.e. the principle of electrowetting. For a single electrode 1062 and the corresponding droplet 1042, the adjustment of the voltage can make the shape of the droplet 1042 change, thereby showing a dynamic effect. When the electrode 1062 is turned on, the applied voltage changes the contact angle to attract the water droplet and stretch the edge of the water droplet to be flat, then the electrode 1062 is gradually turned off, the adjacent electrode 1062 is gradually turned on, one path of continuous switch is continuously pulled, and the liquid droplet 1042 rolls along the direction of turning on the electrode 1062, so that a dynamic effect is presented.
For this embodiment, the entire array electrode 1062 can also move back and forth, and during the back and forth movement, the voltage electric field moves integrally, thereby driving the entire liquid group to change integrally. It will be appreciated that the variation of the present embodiment is more likely. Of course, in this embodiment, the movement of all the electrode 1062 groups may be controlled as a whole by combining the opening and closing control and the back and forth movement control without independent control of each electrode 1062, so that the liquid group may be driven to move as a whole.
As shown in fig. 11, by providing the electronic device 200 according to the second aspect of the present application, including the device middle frame 202 and the cover assembly 100, the display effect of the rear cover of the electronic device 200 can be improved by disposing the cover assembly 100 at the rear side of the device middle frame 202. On this basis, since the electronic device 200 includes the cover plate assembly 100 of any of the embodiments, the beneficial effects of any of the embodiments are achieved, and are not described herein again.
The electronic device 200 may be a smart phone, a tablet, a smart watch, a smart band, or other devices having a rear cover structure.
Further, still include: and the control key 204 is arranged on the equipment middle frame 202, and the control key 204 is electrically connected with the electrode layer 106 of the cover plate assembly.
By arranging the control key 204 electrically connected with the electrode layer 106 on the device middle frame 202, the voltage of the electrode layer 106 can be controlled under the action of the control key 204, so that the control display of the specified pattern or the user-defined pattern can be realized, and the use experience of a user is greatly improved.
