technical field

Embodiments of the present invention relate to the technical field of display devices, and in particular, to a display screen assembly and an electronic device.

Background technique

As the user's demand for the use of electronic devices continues to increase, the screen size of the electronic devices continues to expand. At the same time, the increase in the screen size usually leads to an increase in the overall size of the electronic device, which brings about the problem of inconvenience in portability. Therefore, for the structural design of electronic devices, larger screen size and portability have become a prominent contradiction.

In order to solve the above contradiction, the screen can be set as a flexible display screen, and the flexible display screen can be bent. When the flexible display is in an unfolded state, a relatively large display area can be obtained to meet the user's demand for a larger screen; when the flexible display is in a bent state, the size of the entire flexible display is smaller to facilitate carrying electronics equipment.

However, when the above-mentioned flexible display screen is in an unfolded state, since the flexible display screen is relatively soft, in order to facilitate user operation, a support structure needs to be arranged under the flexible display screen, and the support structure can support the flexible display screen. It can be seen that such an electronic device requires not only a structure for driving the flexible display screen to unfold and bend, but also a structure for supporting the flexible display screen, resulting in a relatively complex structure of the electronic device.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIGS. 1 to 3 , an embodiment of the present invention discloses a display screen assembly, which includes a flexible support portion 100 , a driving mechanism 200 and a flexible display screen 300 .

The flexible support part 100 can be used to support the flexible display screen 300, and the flexible support part 100 has flexibility and can be deformed, so the flexible support part 100 has an unfolded state and a bent state. The flexible support portion 100 is provided with an inner cavity, and the inner cavity can be used for accommodating a working medium, and the working medium here can be solid, liquid or gas, or any combination of the three. When the volume of the working medium changes, the flexible support part 100 can be switched between the unfolded state and the bent state.

The driving mechanism 200 is connected with the flexible support portion 100 , and the driving mechanism 200 can drive the flexible support portion 100 to switch between the unfolded state and the bent state. Optionally, the driving mechanism 200 can realize the volume change of the working medium, so as to drive the flexible support part 100 to switch between the unfolded state and the bent state. In an optional embodiment, the driving mechanism 200 may be a structure such as a semiconductor cooling and heating fin. 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. The state of vaporization and the like changes, so that the volume of the working medium changes, so as to realize the bending of the flexible support portion 100 .

The flexible display screen 300 is disposed on the flexible support part 100 and can be switched between the unfolded state and the bent state with the flexible support part 100 , that is, when the flexible support part 100 is deformed, the flexible display screen 300 can be flexibly supported The flexible display screen 300 is driven and deformed, thereby realizing the unfolding and bending of the flexible display screen 300 . Optionally, the flexible display screen 300 can be an elastic structure, which can undergo elastic deformation and has the ability to recover the deformation. When the flexible support portion 100 deforms and drives the flexible display screen 300 to deform, the flexible display screen 300 has a tendency to restore the deformation. If the flexible support portion 100 no longer exerts any force on the flexible display screen 300, the flexible display screen 300 can restore the deformation. , so as to automatically bend. After this arrangement, no additional structure is required to realize the reset of the flexible display screen 300, so the structure of the display screen assembly is simpler.

In the embodiment of the present invention, when the flexible support part 100 is in the unfolded state, the volume of the inner cavity of the flexible support part 100 is the first volume; when the flexible support part 100 is in the bent state, the volume of the inner cavity is The second volume, the first volume is greater 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 accordingly. At this time, the working medium can apply a force to the flexible support portion 100, so that the flexible support portion 100 is deformed. Thereby switching between the unfolded state and the bent state. Specifically, when the volume of the working medium increases, the flexible support portion 100 can be switched from the folded state to the unfolded state; when the volume of the working medium decreases, the flexible support portion 100 can be switched from the unfolded state to the folded state.

When the flexible support part 100 is in the unfolded state, the flexible support part 100 can support the flexible display screen 300, thereby facilitating the user to operate the flexible display screen 300; when the flexible support part 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 the display screen assembly, the flexible support part 100 can not only drive the flexible display screen 300 to realize unfolding and bending, but also can support the flexible display screen 300 when the flexible display screen 300 is unfolded, without additional setting for supporting the flexible display screen 300 structure, so the structure of the electronic device is simpler.

In an optional technical solution, the above-mentioned driving mechanism 200 may be in contact with the flexible support portion 100 to change the temperature of the working medium in the inner cavity of the flexible support portion 100, thereby promoting the volume of the working medium to change. However, this method has a strong dependence on the heat transfer effect. Once the heat transfer effect is not good, the flexible support portion 100 cannot be reliably switched between the unfolded state and the bent state, thereby affecting the normal operation of the display screen assembly. Work. Based on this, the driving mechanism 200 can be communicated with the inner cavity of the flexible support portion 100 , and the driving mechanism 200 can fill the inner cavity with the working medium and/or extract the working medium in the inner cavity. When the driving mechanism 200 fills the inner cavity with the working medium, as the amount of the working medium continues to increase, its volume will gradually increase, so that the flexible support portion 100 is gradually expanded; when the driving mechanism 200 extracts the working medium in the inner cavity , as the amount of the working medium continues to decrease, its volume will gradually decrease, and the flexible support portion 200 can be switched to the bending state. After adopting this structure, the drive mechanism 200 can change the volume of the working medium more quickly and effectively, thereby realizing the state switching of the flexible support portion 100 more reliably.

It should be noted that the flexible support portion 100 may be additionally provided with a discharge port. At this time, the driving mechanism 200 may only charge the working medium into the inner cavity. discharge. In other embodiments, an additional inlet may be provided on the flexible support portion 100, and after the inlet is opened, the working medium can enter the inner cavity through the inlet. The driving mechanism 200 can only extract the working medium in the inner cavity, so when the working medium needs to be discharged from the inner cavity, the inlet can be closed, and the driving mechanism 200 can be brought into a working state to discharge the working medium.

In an optional embodiment, the driving mechanism 200 includes an output part and an extraction part, and both the output part and the extraction part are communicated with the inner cavity, the output part can fill the working medium into the inner cavity, and the extraction part can extract the liquid in the inner cavity. working medium. Optionally, the output part and the extraction part can be communicated with the inner cavity through the same connection channel, when the inner cavity needs to be filled with working medium, the output part can be in a working state, and the extraction part can be in a non-working state; when 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 in the inner cavity at the same time, so there is no need to open an additional discharge port or an inlet on the flexible support portion 100, and through the output portion and the extraction portion The synergy can realize the filling and extraction of the working medium. Therefore, the structure can simplify the structure of the flexible support portion 100 and prevent the structural strength of the flexible support portion 100 from being reduced due to the opening. Therefore, the structure can improve the structural strength of the flexible support portion 100 .

Optionally, the flexible display screen 300 has a first end 310 and a second end 320. When the flexible support part 100 is in a bent state, the flexible display screen 300 is in a rolled state, and the first end 310 may be located on the flexible display screen 300. the outermost layer, the second end 320 is located at the innermost layer of the flexible display screen 300 . That is to say, when the flexible display screen 300 is bent, it can be rolled layer by layer, so that the flexible display screen 300 has a cylindrical structure in the bent state, and this structure occupies less space, so it is more conducive to reducing the size of the display screen components. size of. At the same time, the method of layer-by-layer curling and layer-by-layer unfolding can more conveniently and reliably realize the bending and unfolding of the flexible display screen 300 .

The flexible support part 100 can support the flexible display screen 300, and the size relationship between the two can be selected flexibly. For example, the size of the flexible support part 100 can be much smaller than the size of the flexible display screen 300, or the size of the flexible support part 100 can be much larger than that of the flexible display screen The size of 300, when the former structure is adopted, the supporting effect of the flexible support part 100 is poor; when the latter structure is adopted, a part of the flexible support part 100 basically does not play a supporting role, which will lead to a waste of structure. Based on this, the flexible support portion 200 can be extended from the first end 310 to the second end 320 of the flexible display screen 300, so that the size of the flexible support portion 100 and the size of the flexible display screen 300 can be better matched, thereby increasing the size of the flexible display screen 300. The contact area between the two is increased, so as to achieve a better support effect, and at the same time, it will not cause waste of structure, so that the cost of the display screen assembly is lower.

In order to more effectively support the flexible display screen 300 at a lower cost, when the flexible support part 100 is in the unfolded state, the orthographic projection of the flexible display screen 300 along its own thickness direction and the orthographic projection of the flexible support part 100 along the thickness direction coincide. In this embodiment, the edge of the flexible display screen 300 is substantially aligned with the edge of the flexible support portion 100 , and the sizes of the two are substantially equal, so that the support area of the flexible support portion 100 for the flexible display screen 300 is larger, and the flexible support portion 100 There is basically no wasted part.

In a further embodiment, the flexible support portion 100 has a third end 110 corresponding to the first end 310 of the flexible display screen 300 and a fourth end 120 corresponding to the second end 320, and the third end 110 is provided with a communication port, The driving mechanism 200 communicates with the inner cavity through the communication port. Since the first end is located at the outermost layer of the flexible display screen, the driving mechanism 200 can be located outside the flexible display screen 300 , which facilitates installation and maintenance of the driving mechanism 200 on the one hand, and prevents the driving mechanism 200 from interfering with the flexible display on the other hand. The screen 300 is bent and unfolded, so as to improve the smoothness of the state switching of the flexible display screen 300 .

Optionally, the flexible support part 100 may be a one-piece structure, and a single flexible display screen 300 may be supported by one flexible support part 100 , but since the size of the flexible display screen 300 is generally large, the size of the flexible support part 100 will also be relatively large It is difficult to accurately control the state change of the flexible support portion 100 , and the problem of poor support effect of the flexible support portion 100 is likely to occur. Based on this, in other embodiments, the number of the flexible support parts 100 may be at least two, the flexible support parts 100 are arranged in sequence along the unfolding direction of the flexible support parts 100 , and the inner cavities of the flexible support parts 100 are isolated from each other . After this arrangement, the size of a single flexible support part 100 is relatively small, and the volume change of the inner cavity of each flexible support part 100 can be individually controlled more accurately, so that the flexible display screen 300 can be supported more accurately. At the same time, after adopting this solution, the states of different flexible support parts 100 can be controlled in a more targeted manner, so as to realize more support modes, so as to meet the usage requirements of users in different states. For example, the flexible display screen 300 can be fully unfolded, partially unfolded, or the like.

In an optional embodiment, in the case where the working medium is gas, the driving mechanism 200 includes an air pump 210 and a gas transmission pipeline 220 communicated with the air pump 210. The gas transmission pipeline 220 has gas transmission ports. The number of the supporting parts 100 is equal, and each gas delivery port is communicated with the inner cavity of each flexible supporting part 100 in a one-to-one correspondence. Compared with the hydraulic drive, the pneumatic drive has higher safety, and the connection between the drive mechanism 200 and the flexible support portion 100, and the disassembly and assembly of the drive mechanism 200 are easier to achieve. Therefore, The drive mechanism 200 is more maneuverable.

In addition, when the working medium is gas, the flexible support portion 200 may be an airbag, the airbag has a certain elasticity, and when the volume of the working medium in the inner cavity of the airbag changes, it can be deformed, so as to better adapt to The volume of the working medium changes, so that the flexible support part 200 is not easily damaged.

The second portion of the display screen 300 is connected to the second body portion. In this embodiment, the first main body part and the second main body part can rotate relative to each other. When the two parts rotate relative to each other, the first part and the second part of the flexible display screen 300 can rotate relative to each other, so as to realize the unfolding and folding of the flexible display screen 300 . In this embodiment, the deformation form of the flexible display screen 300 is relatively simple, so the structure of the entire electronic device is simpler.

In another optional embodiment, the main body of the device may include a casing, and when the flexible support portion 100 is in an unfolded state, the flexible display screen 300 is at least partially located outside the casing, and at this time, the flexible display screen 300 can display ; When the flexible support portion 100 is in a bent state, the flexible display screen 300 is located in the casing, and the flexible display screen 300 is hidden in the casing at this time, so the casing can better protect the flexible display screen 300 . It can be seen that when this structure is adopted, the flexible display screen 300 is not easily damaged due to collision with other objects, so the reliability of the electronic device is higher.
