Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3, an embodiment of the present invention discloses a display screen assembly, which includes a flexible supporting portion 100, a driving mechanism 200, and a flexible display screen 300.
The flexible supporting part 100 may be used to support the flexible display screen 300, and the flexible supporting part 100 has flexibility, which may be deformed, so that the flexible supporting part 100 has an unfolded state and a folded state. The flexible supporting portion 100 is provided with an inner cavity, and the inner cavity can be used for accommodating a working medium, wherein the working medium can be solid, liquid or gas, and can also be any combination of the three. When the volume of the working medium changes, the flexible support portion 100 can be switched between the unfolded state and the folded state.
The driving mechanism 200 is connected to the flexible support 100, and the driving mechanism 200 can drive the flexible support 100 to switch between the unfolded state and the folded state. Alternatively, the driving mechanism 200 may implement a volume change of the working medium to drive the flexible support 100 to switch between the unfolded state and the folded state. In an alternative embodiment, the driving mechanism 200 may be a semiconductor cold-hot plate, and the like, and under the action of the driving mechanism 200, the temperature of the working medium changes, so that the volume of the working medium changes, or the working medium changes in a state such as gasification, so that the volume of the working medium changes, and thus the flexible supporting portion 100 is bent.
The flexible display screen 300 is disposed on the flexible supporting portion 100, and can be switched between an unfolded state and a bent state along with the flexible supporting portion 100, that is, when the flexible supporting portion 100 is deformed, the flexible display screen 300 can be driven by the flexible supporting portion 100, and then deformed, so as to unfold and bend the flexible display screen 300. Alternatively, the flexible display 300 may be an elastic structure, which can be elastically deformed and has the ability to recover the deformation. After the flexible supporting portion 100 deforms and drives the flexible display screen 300 to deform, the flexible display screen 300 has a tendency of restoring deformation, and if the flexible supporting portion 100 does not apply an acting force to the flexible display screen 300 any more, the flexible display screen 300 can restore deformation, so that the flexible display screen is bent automatically. After the arrangement, the resetting of the flexible display screen 300 is realized without additionally arranging a structure, so that the structure of the display screen assembly is simpler.
In the embodiment of the present invention, when the flexible support portion 100 is in the unfolded state, the volume of the inner cavity of the flexible support portion 100 is a first volume; under the condition that the flexible supporting part 100 is in a bending state, the volume of the inner cavity is a second volume, and the first volume is larger than the second volume. When the volume of the working medium in the inner cavity of the flexible support portion 100 changes, the volume of the inner cavity changes, and at the moment, the working medium can apply acting force to the flexible support portion 100, so that the flexible support portion 100 deforms, and the flexible support portion is switched between the unfolding state and the folding state. Specifically, when the volume of the working medium increases, the flexible supporting portion 100 may be switched from the bent state to the deployed state; when the volume of the working medium is reduced, the flexible support portion 100 can be switched from the unfolded state to the folded state.
When the flexible support 100 is in the unfolded state, the flexible support 100 may support the flexible display 300, thereby facilitating a user to operate the flexible display 300; when the flexible supporting portion 100 is in the bent state, the flexible display screen 300 is also in the bent state, so that the size of the display screen assembly is reduced to ensure its portability. In this display screen assembly, the flexible supporting portion 100 can drive the flexible display screen 300 to unfold and bend, and can support the flexible display screen 300 when the flexible display screen 300 is unfolded, and does not need to be additionally provided with a structure for supporting the flexible display screen 300, so that the structure of the electronic device is simpler.
In an alternative embodiment, the driving mechanism 200 may be in contact with the flexible supporting portion 100 to change the temperature of the working medium in the inner cavity of the flexible supporting portion 100, so as to change the volume of the working medium. However, this method has a strong dependency on the heat transfer effect, and once the heat transfer effect is not good, the flexible supporting portion 100 cannot be reliably switched between the unfolded state and the folded state, thereby affecting the normal operation of the display panel assembly. Based on this, the driving mechanism 200 may be in communication with the inner cavity of the flexible supporting portion 100, and the driving mechanism 200 may fill the inner cavity with the working medium and/or extract the working medium from the inner cavity. When the driving mechanism 200 fills the working medium into the inner cavity, the volume of the driving mechanism will gradually increase along with the increasing amount of the working medium, so that the flexible supporting part 100 is gradually unfolded; when the driving mechanism 200 extracts the working medium in the inner cavity, the volume of the driving mechanism is gradually reduced along with the continuous reduction of the amount of the working medium, and the flexible supporting portion 200 can be switched to a bending state. With this structure, the driving mechanism 200 can change the volume of the working medium more quickly and efficiently, thereby more reliably realizing the state switching of the flexible supporting portion 100.
It should be noted that the flexible supporting portion 100 may be additionally provided with a discharge port, and the driving mechanism 200 may only fill the inner cavity with the working medium, and may open the discharge port to discharge the working medium when the working medium needs to be discharged from the inner cavity. In other embodiments, an inlet may be additionally provided on the flexible support 100, and after opening the inlet, the working medium may enter the inner cavity through the inlet. The drive mechanism 200 may only draw working medium from the lumen, and thus when it is desired to expel working medium from the lumen, the inlet may be closed and the drive mechanism 200 brought into an operative state, thereby expelling the working medium.
In an alternative embodiment, the driving mechanism 200 includes an output portion and an extraction portion, both of which are communicated with the inner cavity, the output portion can fill the inner cavity with the working medium, and the extraction portion can extract the working medium in the inner cavity. Optionally, the output part and the extraction part can be communicated with the inner cavity through the same connecting channel, when working media need to be filled into the inner cavity, the output part can be in a working state, and the extraction part can be in a non-working state; when the working medium in the inner cavity needs to be extracted, the extraction part can be in a working state, and the output part can be in a non-working state
At this time, the driving mechanism 200 has the functions of filling the working medium into the inner cavity and extracting the working medium from the inner cavity, so that the working medium can be filled and extracted through the cooperation of the output part and the extraction part without additionally providing a discharge port or an inlet on the flexible supporting part 100. Therefore, the structure can simplify the structure of the flexible supporting part 100, and simultaneously, the problem that the structural strength of the flexible supporting part 100 is reduced due to the hole can be prevented, so the structure can improve the structural strength of the flexible supporting part 100.
Alternatively, the flexible display 300 has a first end 310 and a second end 320, and when the flexible support 100 is in the bent state, the flexible display 300 is in the rolled state, the first end 310 may be located at the outermost layer of the flexible display 300, and the second end 320 may be located at the innermost layer of the flexible display 300. That is to say, the flexible display screen 300 can be curled layer by layer when being bent, so that the flexible display screen 300 is in a cylindrical structure in a bending state, and the space occupied by the structure is smaller, thereby being more beneficial to reducing the size of the display screen assembly. Meanwhile, the mode of curling layer by layer and unfolding layer by layer can realize the bending and unfolding of the flexible display screen 300 more conveniently and reliably.
The flexible supporting portion 100 can support the flexible display screen 300, and the size relationship between the flexible supporting portion 100 and the flexible display screen 300 can be flexibly selected, for example, the size of the flexible supporting portion 100 can be much smaller than that of the flexible display screen 300, or the size of the flexible supporting portion 100 can be much larger than that of the flexible display screen 300, and when the former structure is adopted, the supporting effect of the flexible supporting portion 100 is poor; in the latter configuration, a portion of the flexible support portion 100 does not substantially support the structure, thereby resulting in a waste of the structure. Based on this, can make flexible supporting portion 200 extend to second end 320 from first end 310 of flexible display screen 300 to make the size of flexible supporting portion 100 and the size of flexible display screen 300 can match better, and then increase both areas of contact, so both reached better supporting effect, can not cause the waste of structure again simultaneously, make the cost of display screen subassembly lower.
In order to support the flexible display 300 more efficiently at lower cost, the orthographic projection of the flexible display 300 in the thickness direction thereof coincides with the orthographic projection of the flexible support 100 in the thickness direction thereof with the flexible support 100 in the unfolded state. In this embodiment, the edge of the flexible display screen 300 is substantially aligned with the edge of the flexible support 100, and the two are substantially equal in size, so that the flexible support 100 has a larger support area for the flexible display screen 300, and the flexible support 100 has substantially no waste.
In a further embodiment, the flexible supporting portion 100 has a third end 110 corresponding to the first end 310 of the flexible display panel 300 and a fourth end 120 corresponding to the second end 320, the third end 110 is provided with a communication port, and the driving mechanism 200 is communicated with the inner cavity through the communication port. Because the first end is located the outermost layer of flexible display screen, consequently actuating mechanism 200 can be located the outside of flexible display screen 300, sets up like this and is convenient for on the one hand installation and maintains actuating mechanism 200, and on the other hand also can prevent that actuating mechanism 200 from disturbing flexible display screen 300 and carrying out the operation of bending and expanding to this smoothness when promoting flexible display screen 300 and carrying out the state switching.
Alternatively, the flexible supporting portion 100 may be an integral structure, and a single flexible display screen 300 may be supported by one flexible supporting portion 100, but since the size of the flexible display screen 300 is generally large, the size of the flexible supporting portion 100 may also be large, which causes the condition change of the flexible supporting portion 100 not to be easily and accurately controlled, and the problem of poor supporting effect of the flexible supporting portion 100 is easily caused. Based on this, in other embodiments, the number of the flexible supports 100 may be at least two, each of the flexible supports 100 is sequentially arranged along the unfolding direction of the flexible support 100, and the inner cavities of each of the flexible supports 100 are isolated from each other. Thus, the size of the single flexible supporting part 100 is relatively small, and the volume change condition of the inner cavity of each flexible supporting part 100 can be controlled independently and accurately, so that the flexible display screen 300 can be supported more accurately. Meanwhile, by adopting the scheme, the states of different flexible supporting parts 100 can be controlled more pertinently, so that more supporting modes are realized, and the use requirements of users in different states are met. For example, a fully extended, partially extended, etc. mode of the flexible display 300 may be implemented.
In an alternative embodiment, in the case that the working medium is air, the driving mechanism 200 includes an air pump 210 and an air transmission pipeline 220 communicated with the air pump 210, the air transmission pipeline 220 has air transmission ports, the number of the air transmission ports is equal to the number of the flexible supporting portions 100, and each air transmission port is communicated with the inner cavity of each flexible supporting portion 100 in a one-to-one correspondence manner. The pneumatic driving method has higher safety than the hydraulic driving method, and the driving mechanism 200 has higher operability because the connection between the driving mechanism 200 and the flexible supporting portion 100, the removal and installation of the driving mechanism 200, and other operations are easier to achieve.
In addition, under the condition that the working medium is gas, the flexible supporting portion 200 can be an air bag which has certain elasticity, and when the volume of the working medium in the inner cavity of the air bag changes, the air bag can deform so as to better adapt to the volume change of the working medium, so that the flexible supporting portion 200 is not easy to damage.
Based on the display screen assembly described in any of the above embodiments, an embodiment of the present invention further discloses an electronic device, which includes a device main body and the display screen assembly described in any of the above embodiments, and the display screen assembly is connected to the device main body, so that the display screen assembly can implement a display function.
In an alternative embodiment, the device body may include a first main body portion and a second main body portion, the first main body portion is hinged to the second main body portion, the first portion of the flexible display screen 300 is connected to the first main body portion, and the second portion of the flexible display screen 300 is connected to the second main body portion. In this embodiment, the first main body portion and the second main body portion can rotate relatively, and when the first main body portion and the second main body portion rotate relatively, the first portion and the second portion of the flexible display screen 300 can rotate relatively, so that the flexible display screen 300 can be unfolded and folded. In this embodiment, the flexible display 300 is relatively simple in its deformation form, so that the whole electronic device is simpler in structure.
In another alternative embodiment, the device main body may include a housing, and when the flexible support portion 100 is in the unfolded state, the flexible display screen 300 is at least partially located outside the housing, and the flexible display screen 300 may display; under the condition that the flexible supporting portion 100 is in the bent state, the flexible display 300 is located inside the housing, and at this time, the flexible display 300 is hidden inside the housing, so the housing can better protect the flexible display 300. It can be seen that, with such a structure, the flexible display screen 300 is not easily damaged by collision with other objects, and thus the reliability of the electronic device is higher.
The electronic device disclosed in the embodiment of the present invention may be a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), an electronic game machine, or the like, and the specific type of the electronic device is not limited in the embodiment of the present invention.
