As shown in fig. 1, the stretchable panel assembly 10 includes a stretchable display module 1, an adsorption layer 2, and a support substrate 3.
The stretchable display module 1 is provided with a display surface and a non-display surface which are opposite to each other, and is used for displaying pictures during operation. The stretchable display module 1 includes a support film (BPF), an organic light-Emitting Diode (OLED), a Thin film encapsulation layer (Thin-Film Encapsulation, TFE), a Polarizer (Polarizer), and a Colorless Polyimide (CPI) -cover plate, which are sequentially stacked. The thickness of the stretchable display module 1 may be 0.15mm-0.25mm. The specific structure and function of each layer of the stretchable display module 1 can be referred to the specific structure and function of the related layer in the existing display module, and the same or similar technical effects can be achieved, which are not described herein.
The adsorption layer 2 is attached to the non-display surface of the stretchable display module 1; the thickness of the adsorption layer 2 is 100um-500um. The supporting substrate 3 is disposed on a side of the adsorption layer 2 facing away from the stretchable display module 1. In an embodiment, the support substrate 3 may be stretched simultaneously with the stretchable module.

The sliding connection manner of the first sub-board 31 and the second sub-board 32 may refer to the existing sliding connection manner between any two components, which is not limited in the present application, so long as the two components are in sliding connection, and the surface of the first sub-board 31, which is close to the stretchable display module 1, and the surface of the second sub-board 32, which is close to the stretchable display module 1, are guaranteed to be always level in the sliding process, so that the flatness of the stretchable display module 1 in the stretching process is guaranteed.
Specifically, in order to prevent the stretchable display module 1 from rebounding after being stretched, the supporting substrate 3 is further provided with a self-locking structure, so that the stretched supporting substrate 3 is limited through the self-locking structure, and further the stretched stretchable display module 1 is limited. The self-locking structure can be arranged at the bottom of the supporting substrate 3 or at a bilateral symmetry position; such as at A, B of the second sub-board 32 along the length of the support substrate 3. The specific structure and function of the self-locking structure can be referred to the related structure and function of the existing self-locking structure, and the same or similar technical effects can be achieved, and the detailed description is omitted herein.
The adsorption layer 2 or the support substrate 3 may be configured in a first state and a second state, and when the adsorption layer 2 or the support substrate 3 is configured in the first state, an adsorption force is provided between the adsorption layer 2 and the support substrate 3, and the adsorption force adsorbs the support substrate 3 to the adsorption layer 2, so as to support the stretchable display module 1, thereby ensuring the flatness of the stretchable display module 1. When the adsorption layer 2 or the support substrate 3 is configured in the second state, the adsorption force between the adsorption layer 2 and the support substrate 3 disappears, so that the stretchable display module 1 is stretched, the size of the stretchable display module 1 can be adjusted according to the actually required display size, richer content can be presented, man-machine interaction is more vivid and more efficient, and user experience of a more stick is brought; compared with the existing folding screen or rolling screen, the whole thickness of the folding screen or rolling screen is thinner, and the whole machine heat dissipation is facilitated. Simultaneously compare in adsorbed layer 2 and supporting baseplate 3 closely laminate through the adsorption affinity, then carry out tensile scheme to stretchable display module assembly 1, can effectively reduce the tensile resistance between adsorbed layer 2 and the supporting baseplate 3 in the tensile process to reduce the required power of tensile resistance between the two of overcoming in the tensile process, make whole tensile process more laborsaving, convenient.
In one embodiment, the adsorption layer 2 and the support substrate 3 are adsorbed by magnetic adsorption force. In this embodiment, at least one of the adsorption layer 2 and the support substrate 3 includes a magnetic material; the first state is an electrified state, and the second state is a power-off state; in the first state, the magnetic material generates magnetism to attract the support substrate 3 to the attraction layer 2 by the magnetic attraction force; in the second state, the magnetic attraction force between the attraction layer 2 and the support substrate 3 disappears.
In a specific embodiment, one of the adsorption layer 2 and the support substrate 3 includes a metal material capable of being magnetically attracted, and the other includes a magnetic material. Wherein, the metal material capable of being magnetically attracted comprises iron, cobalt, nickel, alloys thereof and the like. The magnetic material comprises micro electromagnet material, ferrite material, nickel base alloy, etc.
In order to ensure that the support substrate 3 has a good support strength while the adsorption layer 2 and the support substrate 3 are tightly attached by the adsorption force. In one embodiment, the support substrate 3 comprises a metallic material that can be magnetically attracted; the adsorption layer 2 comprises an electromagnetic material. The present application will be described with this example. In addition, because the adsorption layer 2 can be synchronously stretched along with the stretchable display module 1 in the stretching process of the stretchable display module 1, in order to enable the adsorption layer 2 to have better stretching performance, the adsorption layer 2 further comprises an elastic material; the electromagnetic material may be dispersed between the elastic materials in particular to ensure uniformity of deformation of the adsorption layer 2 during stretching. The elastic material related to the application can be hyperbranched polyurethane elastic material.
Of course, as shown in fig. 4, fig. 4 is a top view of an adsorption layer according to an embodiment of the application; the adsorption layer 2 may also include an elastic layer 21 made of an elastic material and a plurality of electromagnets 22, where the elastic layer 21 has a plurality of grooves or holes, and the plurality of electromagnets 22 are in one-to-one correspondence with and embedded in the plurality of grooves or holes. Wherein the magnetic body is made of a magnetic material. Thus, the absorbent layer 2 can be ensured to be internally configured into different first states and second states, and the tensile property of the absorbent layer 2 can be effectively ensured.
In another embodiment, unlike the above embodiment, it is: the support substrate 3 includes a magnetic material, and the adsorption layer 2 includes a metal material that can be magnetically attracted. In one embodiment, the adsorption layer 2 may be a metal film layer, and in order to ensure that the metal film layer has better tensile properties, the effect of the metal film layer on the tensile properties of the whole stretchable screen assembly 10 is reduced, and the thickness of the metal film layer is 1um to 10um. In another embodiment, the adsorption layer 2 further comprises an elastic material, and the magnetically attractable metal material is uniformly dispersed between the elastic materials. In yet another embodiment, similar to the structure shown in fig. 4, the adsorption layer 2 includes an elastic layer 21 and several metal bodies (not shown in fig. 4); the elastic layer 21 is provided with a plurality of grooves or holes which are arranged at intervals, and a plurality of metal bodies are in one-to-one correspondence with the grooves or holes and are embedded in the grooves or holes; wherein, the material of the metal body is a metal material which can be magnetically attracted. This not only ensures that the adsorption layer 2 can be adsorbed by the support substrate 3, but also effectively ensures the tensile properties of the adsorption layer 2.
In yet another embodiment, the adsorption layer 2 and the support substrate 3 may each also comprise a magnetic material. In this embodiment, the adsorption layer 2 and the support substrate 3 may be simultaneously configured in the first state to simultaneously generate magnetism; however, it should be emphasized that in this embodiment, if the stretchable panel assembly 10 is not stretched, the adsorption layer 2 and the support substrate 3 should be simultaneously configured in the second state to simultaneously vanish the magnetism. It will be appreciated that the magnetism of the magnetically attractable layer 2 and the support substrate 3 are opposite to each other. Of course, in this embodiment, when it is necessary to stretch the stretchable panel assembly 10, one of the adsorption layer 2 and the support substrate 3 may be configured to be in the first state, so that one of the two is magnetic, and tight connection of the two is achieved by magnetic adsorption.
In yet another embodiment, unlike the above embodiment, the adsorption layer 2 and the support substrate 3 each include a conductive material. The conductive material may be a conductive metal such as aluminum, silver, alloys thereof, and the like. In the first state, the adsorption layer 2 and the support substrate 3 are both charged and are different in polarity, so that the support substrate 3 is adsorbed on the adsorption layer 2 by electric adsorption between the adsorption layer 2 and the support substrate. In the second state, neither the adsorption layer 2 nor the support substrate 3 is charged, and the electric adsorption force therebetween disappears.
In this embodiment, in order to ensure the tensile properties of the adsorption layer 2 and the support substrate 3, at least the adsorption layer 2 in the adsorption layer 2 and the support substrate 3 further include an elastic material, and the distribution manner of the conductive material and the elastic material is similar to that of the conductive material and the elastic material that can be magnetically attracted, which are described above, and detailed descriptions thereof are omitted herein. The supporting substrate 3 may be a structure of the first sub-board 31 and the second sub-board 32 that are slidably connected as shown in fig. 3, or a structure similar to the adsorption layer 2 and further including an elastic material, that is, the conductive material is uniformly dispersed in the elastic material, or the elastic material forms the elastic layer 21, and the conductive material is made into a conductive body, and the conductive body is embedded in a plurality of grooves of the elastic layer 21, which is described in detail in the related description of fig. 4.
Referring to fig. 5 and 6, fig. 5 is a schematic diagram of a laminated structure of a stretchable panel assembly according to another embodiment of the present application. FIG. 6 is a schematic diagram of a controller according to an embodiment of the present application; unlike the stretchable screen assembly 10 provided by the embodiments corresponding to fig. 1 to 4 described above, the stretchable screen assembly 10 further includes a tension sensor 4 and a controller 5.
The tension sensor 4 is used for sensing a tension value received by the stretchable display module 1. It can be understood that the stretchable display module 1 is subjected to a certain tensile force during the stretching process, so as to deform; the tension sensor 4 is specifically configured to sense a tension value of the tension. As shown in fig. 5, the stretchable screen assembly 10 further includes a tension detecting film 6, and the tension sensor 4 is specifically integrated in the tension detecting film 6. In particular, the tension detecting film 6 may be made of a conductive material that undergoes a change in resistance when the tension detecting film 6 is stretched. The tension detecting film 6 determines the tension value of the stretchable display module 1 based on the change of its resistance.
It will be appreciated that under small deformations, the strain epsilon at a point of an elastic element is proportional to the force exerted by the elastic element and also proportional to the elastic deformation, as is known from the material mechanics. For the sensor, differential full bridge measurement is generally adopted, namely, the bonded strain gages form a bridge circuit, namely, the R1, R2, R3 and R4 strain gages with equal resistance values are actually 4 (or 8 strain gages), namely, R1=R2=R3=R4, when the sensor is subjected to the action of external force (tensile force or pressure), the elastic element of the sensor generates strain to change each resistance value, and the change values are respectively delta R1, delta R2, delta R3 and delta R4, at this time, the originally balanced bridge becomes unbalanced, and the bridge circuit has voltage output. In short, the external force P causes deformation of the strain gauge in the sensor, resulting in unbalance of the bridge, thereby causing variation of the output voltage of the sensor, and we can know the magnitude of the force or the deformation of the stretchable display module 1 by measuring the variation Δv of the output voltage. Wherein the deformation amount Δs=epsilon× Δv of the stretchable display module 1; wherein epsilon is related to the factors such as the elastic element material, the film thickness of the tension sensor film and the like; deltaV is the voltage output variation.
As shown in fig. 5, the projection areas of the stretchable display module 1, the adsorption layer 2 and the tensile force detection film layer 6 on the support substrate 3 are the same, and the projection areas of the stretchable display module 1, the adsorption layer 2 and the tensile force detection film layer 6 on the support substrate 3 are the same as the cross-sectional area of the support substrate 3.
The controller 5 comprises an electromagnetic control module 51, and the electromagnetic control module 51 is connected with the tension sensor 4; when the electromagnetic control module 51 responds to the change of the tension value of the tension sensor 4, the adsorption layer 2 is controlled to be converted into a second state from the first state; the controller 5 controls the adsorption layer 2 to be converted from the second state to the first state in response to the constant tension value of the tension sensor 4. It can be understood that in the formula f= k.s, F is a tensile force, k is a rigidity coefficient of the stretchable display module 1, and s is an elongation of the stretchable display module 1. According to the formula, in the stretching process of the stretchable display module 1, that is, when the length of the stretchable display module 1 is continuously changed, the tensile force applied to the stretchable display module is also continuously changed; therefore, when the tension value of the tension sensor 4 changes, it indicates that the stretchable display module 1 is in or about to be in a stretched state or a contracted state at this time; when the tension value of the tension sensor 4 is constant, it indicates that the stretchable display module 1 is not stretched or not shrunk at this time. It will be appreciated that when the tension value of the tension sensor 4 is constant, the stretchable display module 1 is not stretched or contracted, i.e. the display module 1 is at a certain fixed size.
Wherein the electromagnetic control module 51 is triggered in order to prevent malfunction; in a specific embodiment, the electromagnetic control module 51 controls the first state to be converted into the second state in response to the tension value of the tension sensor 4 continuously changing within the first preset time; the electromagnetic control module 51 controls the second state to be converted into the first state in response to the tension value of the tension sensor 4 being continuously constant for a second preset time. The first preset time and the second preset time can be set according to practical situations, which is not limited by the application.
Since the resolution (i.e., resolution) of the stretchable display module 1 is changed when the stretchable display module 1 is stretched; in order to match the corresponding resolution according to the length variation of the stretchable display module 1, the stretchable display module 1 can exhibit a better image quality effect under any size. In a specific embodiment, the controller 5 further comprises a processor 52 and a resolution matching module 53. The processor 52 is connected to the tension sensor 4, and is configured to calculate and send a size change value of the stretchable display module 1 according to the tension value sensed by the tension sensor 4. The size change value is the length change of the stretching display module.
The resolution matching module 53 is connected to the processor 52, and is configured to receive the size change value sent by the processor 52, and match the corresponding resolution to the stretchable display module 1 according to the size change value. Specifically, the resolution matching module 53 determines the area variation of the stretchable display module 1 according to the size variation value, and then matches the corresponding resolution to the stretchable display module 1 according to the area variation. Wherein the resolution is proportional to the area variation.
The resolution herein is understood to be the number of pixels per unit area. The essence of the matching resolution is to match the size of the display area after the stretchable display module 1 is stretched. The size of the matching display area serves to adjust the size of the display content. For example, the icon displayed before stretching is relatively small, and the icon displayed after stretching is large.
Of course, in other embodiments, if the stretchable display module 1 is stretched along two different directions, the tension sensor 4 may be disposed in each direction, and the processor 52 is connected to the tension sensor 4 in each direction, for calculating and sending a size change value of the stretchable display module 1 in each direction according to the tension value sensed by the tension sensor 4 in each direction; the resolution matching module 53 receives the size change value sent by the processor 52, and determines the area change amount of the stretchable display module 1 according to the size change value in each direction; and then matching the corresponding resolution with the stretchable display module 1 according to the area variation.
For example, the stretchable display module 1 is rectangular, and the tension sensors 4 can be integrated along the length direction and the width direction of the stretchable display module 1 respectively; the processor 52 is connected to the tension sensor 4 in each direction, respectively. In a specific stretching process, the stretchable display module 1 can be stretched along the length direction and the width direction of the stretchable display module 1, respectively. The processor 52 calculates and transmits a length dimension change value of the stretchable display module 1 in the length direction according to the tension value sensed in the length direction, and calculates and transmits a width dimension change value of the stretchable display module 1 in the width direction according to the tension value sensed in the width direction; the resolution matching module 53 receives the length dimension change value and the width dimension change value sent by the processor 52, and determines the area change amount of the stretchable display module 1 according to the length dimension change value and the width dimension change value; and then matching the corresponding resolution with the stretchable display module 1 according to the area variation.

Unlike the stretchable screen assembly 10 provided by the embodiment corresponding to fig. 5 described above, the stretchable screen assembly 10 further includes a pressure sensor 7. The projection areas of the stretchable display module 1, the adsorption layer 2 and the tension detection film 6 on the support substrate 3 are the same, and the projection areas of the stretchable display module 1, the adsorption layer 2 and the tension detection film 6 on the support substrate 3 are smaller than the cross-sectional area of the support substrate 3, and the pressure sensor 7 can be arranged at the edge position of the support substrate 3 and positioned on one side surface of the support substrate 3 facing the stretchable display module 1 for sensing and transmitting the pressure value received by the preset position of the stretchable screen assembly 10. It will be appreciated that when the user wishes to stretch the stretchable display module 1, the user may press a designated location whose pressure sensor 7 senses the pressure pressed by the user.
The processor 52 of the controller 5 is connected to the pressure sensor 7 for receiving the pressure value and sending an enabling signal to the electromagnetic control module 51; the electromagnetic control module 51 controls the adsorption layer 2 to be converted from the first state to the second state according to the enabling signal, so that the adsorption layer 2 comprising the electromagnetic material loses magnetism and cannot adsorb the metal substrate, and further the metal substrate cannot support the stretchable display module 1, so that a user can stretch the stretchable display module 1. Wherein the pressure value is greater than zero.
In a specific embodiment, in order to prevent a situation in which a user misoperations occurs. The processor 52 is specifically configured to receive the pressure value and send a first enable signal to the electromagnetic control module 51 in response to the pressure value being greater than a first threshold value; the electromagnetic control module 51 controls the adsorption layer 2 to be converted from the first state to the second state according to the first enabling signal; processor 52 sends a second enable signal to electromagnetic control module 51 in response to the pressure value not being greater than the first threshold value; the electromagnetic control module 51 controls the adsorption layer 2 to be converted from the second state to the first state according to the second enabling signal.
To further prevent a situation of erroneous operation. The processor 52 is specifically configured to receive the pressure value, and send a first enable signal to the electromagnetic control module 51 in response to the pressure value being continuously greater than the first threshold value for a third preset time; the electromagnetic control module 51 controls the adsorption layer 2 to be converted from the first state to the second state according to the first enabling signal; when the pressure value of the processor 52 is not greater than the first threshold value in the fourth preset time, a second enabling signal is sent to the electromagnetic control module 51; the electromagnetic control module 51 controls the adsorption layer 2 to be converted from the second state to the first state according to the second enabling signal. The first threshold, the second threshold, the third preset time and the fourth preset time may be specifically set according to practical situations, which is not limited by the present application.
Further, as shown in fig. 7, the number of the pressure sensors 7 is at least two, and the processor 52 specifically sends a first enabling signal to the electromagnetic control module 51 in response to the pressure values sensed by the at least two pressure sensors 7 being greater than a first threshold value; the electromagnetic control module 51 controls the adsorption layer 2 to be converted from the first state to the second state according to the first enabling signal; processor 52 sends a second enable signal to electromagnetic control module 51 in response to the pressure value of at least one of the at least two pressure sensors 7 being not greater than the first threshold value; the electromagnetic control module 51 controls the adsorption layer 2 to be converted from the second state to the first state according to the second enabling signal. This can further prevent occurrence of a phenomenon of erroneous operation.
Wherein, at least two pressure sensors 7 are arranged on one side surface of the supporting substrate 3 facing the stretchable display module 1. As shown in fig. 7, the number of the pressure sensors 7 may be two, and the two pressure sensors 7 are disposed on two sides of the stretchable display module 1 along the stretching direction of the stretchable display module 1.
In a specific embodiment, when any one of the tension value sensed by the tension sensor 4 and the pressure value sensed by the pressure sensor 7 meets the above-mentioned condition related to the condition for triggering the electromagnetic control module 51, the electromagnetic control module 51 starts to operate, that is, controls the adsorption layer 2 to switch between the first state and the second state. That is, when the tension value sensed by the tension sensor 4 satisfies the above-mentioned condition for triggering the electromagnetic control module 51, the electromagnetic control module 51 starts to operate, and the adsorption layer 2 is controlled to switch between the first state and the second state. When the pressure value sensed by the pressure sensor 7 meets the above-mentioned condition that the electromagnetic control module 51 is triggered, the electromagnetic control module 51 will also start to operate, so as to control the adsorption layer 2 to switch between the first state and the second state. In this way, when one of the tension sensor 4 and the pressure sensor 7 is prevented from being damaged, the adsorption layer 2 or the support substrate 3 can be controlled to be switched between the first state and the second state, and the service life of the stretchable screen assembly 10 is effectively prolonged.
Of course, the electromagnetic control module 51 may start to operate only when the tension value sensed by the tension sensor 4 and the pressure value sensed by the pressure sensor 7 simultaneously satisfy the above-mentioned respective corresponding conditions for triggering the electromagnetic control module 51, that is, the adsorption layer 2 is controlled to switch between the first state and the second state. Thus, the phenomenon of misoperation can be effectively prevented.

Meanwhile, when the adsorption layer 2 or the support substrate 3 is configured in the second state, the adsorption force between the adsorption layer 2 and the support substrate 3 disappears to stretch the stretchable display module 1, so that the size of the stretchable display module 1 can be adjusted according to the actually required display size, richer content can be presented, man-machine interaction is more vivid and more efficient, and user experience of a more stick is brought; compared with the existing folding screen or rolling screen, the whole thickness of the folding screen or rolling screen is thinner, and the whole machine heat dissipation is facilitated.
