Thereby realizing the separation and curling of the flexible supporting substrate 2 and the flexible display module 1; compare in flexible supporting substrate and the range upon range of scheme of being connected with whole curly with flexible display module, not only can be when flexible supporting substrate 2 and flexible display module 1 are laminated each other, support flexible display module 1 through flexible supporting substrate 2, and curl the thickness that can not bodiness flexible display module 1 through the separation, and then can effectively reduce flexible display module 1 because of thickness is great, and take place the probability of the layering problem between layer and the layer at the in-process that curls, the realization improves the support intensity to flexible display module 1 when not increasing flexible display module 1 thickness.
Specifically, the orthographic projections of the second rotating shaft 5b and the first rotating shaft 4b on the plane of the display surface of the rollable device 10 are arranged in a staggered manner, so as to avoid the problem that the second display part 1b and the second supporting part 2b interfere with each other in the rolling process. The plane of the display surface of the rollable device 10 is the horizontal plane of the first display portion 1a.
The second driving member 5a is connected to the second rotating shaft 5b for driving the second rotating shaft 5b to rotate. In a particular embodiment, as shown in fig. 1, the second driver 5a may be embodied as a coil spring. The first end of the second driving member 5a is fixedly connected with the bracket 3. A first one of the plurality of second gears 5c, which mesh with each other, is connected to a second end of the second driver 5 a.

The end gear of the plurality of second gears 5c engaged with each other is connected to the second rotating shaft 5b, and the end gear of the plurality of second gears 5c drives the second rotating shaft 5b to rotate.
Specifically, after the stretching starts, the second rotating shaft 5b rotates in a first direction (e.g., counterclockwise) to unfold the second supporting portion 2b; meanwhile, the second rotating shaft 5b drives the tail end gear of the plurality of second gears 5c fixedly connected with the second rotating shaft to rotate; the end gear drives the second gear 5c engaged therewith to rotate, thereby gradually driving the first gear of the plurality of second gears 5c to rotate, and the first gear drives the coil spring fixedly connected therewith to tighten.

In a particular embodiment, the second crimping mechanism 5 may also include two second drivers 5a and two sets of intermeshing second gears 5c. A second driving member 5a and a set of second gears 5c engaged with each other may be respectively disposed at two ends of the second rotating shaft 5b to respectively apply an acting force to two ends of the second rotating shaft 5b to rotate in the second direction.
In each group of the plurality of mutually meshed second gears 5c, one or more second gears 5c can be further arranged between the first gear and the end gear, so that the position of the first gear relative to the first rotating shaft 4b is adjusted through the one or more second gears 5c, the second driving member 5a is enabled to avoid the position of the first rotating shaft 4b, and the influence of the second driving member 5a on the winding thickness of the first rotating shaft 4b is avoided.
The specific connection and arrangement of the plurality of second gears 5c and the bracket 3, the second driving member 5a, and the second rotating shaft 5b, which are engaged with each other, are similar to the specific connection and arrangement of the plurality of first gears 4c and the bracket 3, the first driving member 4a, and the first rotating shaft 4b, which are engaged with each other, and thus, for details, reference may be made to the above, and details are not repeated herein.
As can be understood by those skilled in the art, since the coil spring occupies a larger area, the axis of the coil spring is relatively thicker, and if the flexible display module 1 or the flexible support substrate 2 is directly curled by using the central axis of the coil spring, the overall thickness of the curled flexible display module 1 and the curled flexible support substrate 2 is thicker, and the occupied area is larger. Therefore, the first rotating shaft 4b and the second rotating shaft 5b which are different from the central shaft of the coil spring are arranged, so that the diameter of the thin rotating shaft can be selected to be smaller according to actual requirements, namely, the thin rotating shaft is used as a reel of the flexible display module 1 and the flexible supporting substrate 2, and the overall thickness of the flexible display module 1 and the flexible supporting substrate 2 after being curled can be reduced; the thickness is the radius or diameter of the wound product. Of course, in other embodiments, the central axis of the coil spring can be directly used as the reel for the flexible display module 1 and the flexible support substrate 2.
Of course, in other embodiments, the first driving member 4a and the second driving member 5a may also be other power sources, and the first driving member 4a and the second driving member 5a are directly connected to the corresponding rotating shafts to drive the corresponding rotating shafts to rotate synchronously.
Referring to fig. 8-10, fig. 8 is a schematic diagram of an assembled crimpable device 10 of fig. 1 according to another embodiment of the present application; FIG. 9 is a disassembled schematic view of FIG. 8; fig. 10 is a schematic view of the crimpable device 10 shown in fig. 8 with the first display portion and the first support portion removed. The telescopic mechanism 6 is connected with the bracket 3 and can move towards the direction close to or far away from the bracket 3, so as to support the flexible display module 1 and the flexible supporting substrate 2 which are mutually attached.
In a particular embodiment, the telescopic mechanism 6 comprises a housing 61 and a support mechanism 62. The first support part 2a and the first display part 1a are sequentially stacked on one side surface of the housing 61; the first display portion 1a is the smallest effective display area of the rollable device 10. Specifically, referring to fig. 1 and 10, the housing 61 is shown as a U-shaped structure including a bottom wall and two opposite side walls disposed on the bottom wall. The two ends of the first supporting part 2a and the first display part 1a are respectively lapped on the ends of the two side walls, which are far away from the bottom wall. In this embodiment, the system board 60 of the crimpable device 10 may be specifically disposed within a housing 61; and a side surface of the system board 60 facing away from the bottom wall may be flush with a side surface of both side walls of the housing 61 facing away from the bottom wall, so that the first support part 2a and the portion of the first display part 1a are supported by the system board 60, thereby ensuring the overall flatness of the first display part 1a. Wherein the system board 60 is used to illuminate and control the active display area of the rollable device 10 for display; the specific structure and function of the system board 60 are the same as or similar to those of a control system in an existing display terminal, and are not described in detail herein.
One end of the supporting mechanism 62 is slidably connected to the housing 61 to slide out of or into the housing 61, the other end of the supporting mechanism 62 is fixedly connected to the bracket 3, and the supporting mechanism 62 is used for supporting the second display portion 1b extending from the first rotating shaft 4b and the second supporting portion 2b extending from the second rotating shaft 5 b. It will be appreciated that in the crimpable device 10 during stretching, the support mechanism 62 slides out of the housing 61 and the distance between the housing 61 and the stand 3 increases; in the winding process of the crimpable device 10, the supporting mechanism 62 slides into the housing 61, and the distance between the housing 61 and the frame 3 is shortened. Wherein, because first display part 1a and first supporting part 2a are all fixed with casing 61, consequently, supporting mechanism 62 can stretch or the rolling along with flexible display module assembly 1 and flexible supporting substrate 2 in step to make this supporting mechanism 62 satisfy the demand of different effective display area areas.
Specifically, as shown in fig. 1 and 10, the supporting mechanism 62 includes a multi-stage supporting member 621, one end of the multi-stage supporting member 621 is slidably connected to the housing 61, and the other end is fixedly connected to the connecting lug 31 of the bracket 3; and the adjacent two stages of supporting pieces 621 are connected in a sliding manner, so that the length of the supporting mechanism 62 is adjustable; therefore, the adjustable distance range between the shell 61 and the support 3 can be enlarged, and the supporting mechanism 62 is small in size and convenient to store. Wherein the multi-stage support 621 begins to slide out of the housing 61 under tension during the stretching process. During the winding process, the multi-stage supporting member 621 is synchronously contracted by the traction force of the second display part 1b and the second supporting part 2b, and slides into the housing 61.
Specifically, the multi-stage supporting member 621 is connected in a drawer type. Each support 621 includes two opposing support bars 622. In two adjacent support rods 622 of the two adjacent support members 621, one support rod 622 has a sliding slot, and the other support rod 622 has a sliding block matching with the sliding slot, and the two support rods 622 are slidably connected by the sliding block sliding in the sliding slot. Of course, the support 621 and the housing 61 may be slidably connected by a sliding groove and a sliding block, which is not limited in this application.
The locking mechanism is used for locking the relative motion between the telescopic mechanism 6 and the bracket. The locking mechanism can be a clamp, a buckle and other structures capable of realizing fixation and limiting, and the structure for realizing the self-locking function can be referred to in the prior art, and is not described in detail herein. It will be appreciated that the release of the locking mechanism allows for either a stretching process or a winding process. The locking mechanism locks, i.e., locks, the multi-stage support 621 and prevents the multi-stage support 621 from sliding relative to each other, so as to limit the effective display area of the rollable device 10 to the size of the current area.
In a particular embodiment, as shown in fig. 3, the crimpable device 10 further comprises a first roller 8a and a second roller 8b. The two ends of the first roller 8a are respectively connected to the first baffle 3a and the second baffle 3b, the second display part 1b of the flexible display module 1 is positioned on the surface of one side of the first roller 8a, which is far away from the second support part 2b, and drives the first roller 8a to rotate in the stretching process, so that the second display part 1b is in smooth transition between curling and flattening; thereby reducing damping and reducing tension; and to avoid the occurrence of creases, cracks, or the like, thereby protecting the second display section 1b.
Two ends of the second roller 8b are respectively connected to the first baffle 3a and the second baffle 3b, and the second supporting part 2b of the flexible supporting substrate 2 is positioned on the surface of one side of the second roller 8b, which is far away from the second display part 1b, and drives the first roller 8a to rotate in the stretching process, so that the second supporting part 2b is in smooth transition between curling and flattening; thereby reducing damping and reducing tension; and to avoid the occurrence of creases or cracks, etc., thereby protecting the second support portion 2b.
The carrying plate 7 is connected between the first barrier 3a and the second barrier 3b, and between the first roller 8a and the second roller 8b, for carrying a portion of the second display part 1b developed from the first rotating shaft 4 b.
In a specific embodiment, at least one of the second supporting portion 2b of the flexible supporting substrate 2 and the second display portion 1b of the flexible display module 1 includes an inductive element; the sensing element is used for sensing the received trigger data.
The control element is connected with the sensing element and used for determining whether the second display part 1b of the flexible display module 1 is unfolded from the first rotating shaft 4b or not according to the trigger data of the sensing element and controlling the second display part 1b and the first display part 1a of the flexible display module 1 unfolded from the first rotating shaft 4b to be effective display areas; through the discernment of effective display area, the corresponding effective display area of lighting to realize that flexible display module assembly 1 divides the region to light, with the size of the effective display area of accurate control flexible display module assembly 1, compare in the scheme that flexible display module assembly 1's whole region all carries out the demonstration, can effectively reduce flexible display module assembly 1's energy consumption.
In one embodiment, the sensing element is disposed on the flexible supporting substrate 2, and the sensing element may be a pressure sensor for sensing pressure data received by the pressure sensor. In this embodiment, the control component determines whether the second display portion 1b of the flexible display module 1 is unfolded from the first rotating shaft 4b according to the pressure data sensed by the pressure sensor, and controls the portion of the second display portion 1b unfolded from the first rotating shaft 4b and the first display portion 1a to be the effective display area of the rollable device 10.
Of course, in other embodiments, the sensing element may also be a photosensitive element, for example, the photosensitive element may be a photosensor, a photodiode, a photoresistor, or the like.
In particular, see fig. 6 and 7. The at least second supporting portion 2b of the flexible supporting substrate 2 may further include a semiconductor material film 22, the semiconductor material film 22 and the ferromagnetic substrate 21 are stacked, and when the flexible display module 1 and the flexible supporting substrate 2 are attached to each other, the semiconductor material film 22 is located on one side of the non-display surface of the flexible display module 1 and located between the flexible display module 1 and the ferromagnetic substrate 21.
In this embodiment, the sensing elements are integrated on the semiconductor material layer 22, and the sensing elements can be integrated on the entire semiconductor material layer 22 and uniformly distributed on the semiconductor material layer 22. Thus, the sensing element can sense the pressure applied to each position of the semiconductor material film layer 22, so that the control element can determine the portion, in the flattened state, of the second display part 1b of the flexible display module 1 according to the pressure data size of each position detected by the sensing element, and further determine the effective display area of the flexible display module 1. The specific structure and material of the sensing element integrated in the semiconductor material film 22 can be referred to the specific structure and material of the conventional semiconductor material film pressure sensor. Of course, the sensing element may be specifically integrated in other regions of the semiconductor material layer 22 different from the first fixed end thereof.
In this embodiment, when the second display portion 1b and the second supporting portion 2b are attached to each other, since the ferromagnetic substrate 21 has a magnetic attraction force to the metal substrate 12, the magnetic attraction force further applies a pressure to the semiconductor material film 22, and the sensing element on the semiconductor material film 22 senses the magnetic attraction force, so as to obtain the current pressure data.
In some embodiments, the number of the sensing elements is multiple, and the sensing elements are correspondingly distributed at different positions of the semiconductor material film layer 22, when the flexible display module 1 is gradually stretched from the curled end to increase the flattening area or is rolled back from the free end to the first reel, the sensing elements at different positions are subjected to corresponding pressures to generate corresponding pressure values, so as to determine that the corresponding area state is flattened or curled, and perform lighting and extinguishing or resolution matching operations on the display screen. Specifically, referring to fig. 3, when the second supporting portion 2b of the flexible supporting substrate 2 and the second display portion 1b of the flexible display module 1 are separately curled on the corresponding rotating shafts, the pressure data sensed by the sensing element is not less than the first pressure threshold. When the second supporting part 2b of the flexible supporting substrate 2 and the second display part 1b of the flexible display module 1 are unfolded from the corresponding rotating shafts, the pressure data sensed by the sensing element is smaller than a first pressure threshold and larger than a second pressure threshold; or the pressure data is equal to the second pressure threshold. The first pressure threshold is greater than the second pressure threshold, and specific values of the first pressure threshold and the second pressure threshold may be set according to actual conditions, which is not limited in this application.
In a specific embodiment, referring to fig. 11, fig. 11 is a schematic structural diagram of a control element provided in an embodiment of the present application. The control element includes a control module 91. The control module 91 is connected with the pressure sensor; in response to the pressure data being smaller than the first pressure threshold and greater than or equal to the second pressure threshold, the control module 91 controls the first display portion 1a and the second display portion 1b having the area corresponding to the pressure data to be the effective display area, so as to light up the effective display area for displaying the image.
Further, the control module 91 controls the second display section 1b having the area corresponding to the pressure data not to perform the image display in response to the pressure data not being less than the first pressure threshold value. For example, the portion of the second display portion 1b in the rolled state is controlled to be in the off state or the non-operating state, so as to reduce the power consumption of the second display portion 1b. It can be understood that the portion of the second display portion 1b that is not currently displayed with an image can still be displayed after being subsequently stretched to the flattened state.
The following illustrates a specific scheme for determining the effective display area of the flexible display module 1.
The inductive element distribution area is sequentially divided into several areas along the crimping direction of the crimpable device 10. Take ten regions as an example. The portion of the flexible display module 1 corresponding to the first region forms a first display portion 1a. In an embodiment, if the pressure data sensed by the sensing elements corresponding to the second, third, and fourth regions is smaller than the first pressure threshold and larger than the second pressure threshold, the control element determines that the portions of the flexible display module 1 corresponding to the second, third, and fourth regions are unfolded from the first rotation axis 4b and attached to the flexible support substrate 2. If the pressure data sensed by the sensing elements corresponding to the fifth area and the sixth area is the second pressure threshold, the control element determines that the portions of the flexible display module 1 corresponding to the fifth area and the sixth area are unfolded from the first rotating shaft 4b but are not attached to the flexible support substrate 2. If the pressure data sensed by the sensing elements corresponding to the seventh area to the tenth area is not less than the first pressure threshold value; the control element determines that the portions of the flexible display module 1 corresponding to the seventh to tenth areas are wound on the first rotating shaft 4 b. At this time, the control element controls the portions of the flexible display module 1 corresponding to the first region, the second region, the third region, the fourth region, the fifth region, and the sixth region to be the effective display regions of the rollable device 10.
In some embodiments, when the magnitude of the stress on the sensing element in the corresponding region is detected, the state of the corresponding region is prevented from being detected by mistake by determining whether the region area of the pressure data distribution is larger than the contact area of the touch tip or the touch control tip of the finger.
In some embodiments, the control module 91 further obtains the area size of the active display area according to the pressure data sensed by the sensing element. Since the rollable device 10 is in the process of stretching or rolling, the area of the portion of the second display portion 1b that is unwound from the first rotating shaft 4b changes in real time, that is, the area of the effective display area of the flexible display module 1 changes in real time. In order to accurately and rapidly match the corresponding resolution for the flexible display module 1, the effective display area of the flexible display module 1 can be ensured to have a better image quality effect under any area size, and the user experience is improved. The control element also includes a resolution matching module 92.
The resolution matching module 92 is connected to the control module 91, and is configured to match a corresponding resolution to the effective display area determined by the control module 91. Specifically, the resolution matching module 92 matches the corresponding resolution to the flexible display module 1 according to the area variation value of the flexible display module 1. Wherein the resolution is proportional to the area variation. It should be noted that the resolution here is understood as the number of pixels per unit area. The essence of the matching resolution is that the resolution matches the size of the area of the effective display area of the flexible display module 1. The effect of matching the area size of the effective display area is to adjust the size of the display content when the effective display area displays the screen. For example, when the area of the effective display area is small, the icons displayed by the flexible display module 1 are small; when the area of the effective display area is large, the icon displayed by the flexible display module 1 becomes large.
In an embodiment, the flexible display module 1 of the rollable device 10 generally has a touch function to control the display of the flexible display module 1. However, the area where the image display is not performed, such as the portion of the flexible display module 1 in the curled state, is easily touched, resulting in an erroneous operation of the flexible display module 1. As shown in fig. 11, the control device further includes a touch module 93, where the touch module 93 is connected to the control module 91 and is used for controlling the effective display area determined by the control module 91 to have a touch function. Only the effective display area of the flexible display module 1 has a touch function, so that the problem of misoperation caused by touching other areas can be effectively avoided; and this scheme can make this curlable device 10 match the corresponding touch-control area according to the real-time change of the effective display area of the flexible display module assembly 1, in order to guarantee this curlable device 10 effective display area has touch-control function all the time. The specific scheme for controlling the effective display area to be the touch area by the touch module 93 can refer to the specific scheme of the existing flexible display module 1 with the touch function, and is not described herein again.
The rollable device 10 provided by the embodiment adopts a separated rolling support scheme, so that the support strength of the flexible display module 1 is improved while the thickness of the flexible display module 1 is not increased, and the probability of the layering problem of the flexible display module 1 is reduced. Simultaneously, whether the second display part 1b of confirming flexible display module assembly 1 through the control element according to sensing element's trigger data launches from first pivot 4b, and control second display part 1b from first pivot 4b go up the flat part of exhibition and first display part 1a be effective display area, thereby realize that flexible display module assembly 1's subregion is lighted, with accurate control flexible display module assembly 1's effective display area, compare in the scheme that whole flexible display module assembly 1 of control all carries out the demonstration, can effectively reduce flexible display module assembly 1's energy consumption, and can improve the degree of accuracy of the effective display area of confirming.

The specific method for determining the effective display area by the control module 91 according to the trigger data can be seen from the related description of the rollable device 10 provided in the above embodiment.
Step S2: matching the corresponding resolution to the effective display area; and/or enabling the effective display area to have a touch function.
In a specific implementation process, the resolution matching module 92 may match the corresponding resolution to the effective display area determined by the control module 91. The effective display area is controlled by the touch module 93 to have a touch function. Specific methods can be found in the related description of the crimpable device 10 provided in the above embodiments.
