DETAILED DESCRIPTION

[0047] In order to make the objectives, technical solutions, and superiorities of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure.

[0048] It should be understood that when a layer or element is referred to as being "on" another layer or substrate, it can be directly on the other layer or substrate, or intervening layers can also be present.

[0049] The flexible display device application market is more and more favored by the market, and the flexible screen mobile phone is a commonly used flexible display device. The flexible screen mobile phone refers to a mobile phone using a screen that can be bent and has good flexibility. Compared with the traditional screen, the flexible screen has obvious advantages, not only providing a new use effect for the user, but also being more compact in size and lower in power consumption, and the screen has flexibility, reducing the risk of screen breakage.

[0050] With the development of flexible display, various forms of flexible display devices have appeared, such as folding display devices, sliding roll display devices, etc. Among them, the sliding roll display device, as a new type of display equipment, can steplessly adjust the screen size of the sliding roll display screen according to actual needs, and as a new flexible display mode, has great application value. However, when the sliding roll display device slides open, the sliding open area is suspended relative to the fixed area, and the greater the weight of the sliding open area, the greater the support force required by the sliding roll device during use, thereby reducing the user's use experience. The weight of the sliding open area of the sliding roll device is related to the thickness of the sliding open area, therefore, how to reduce the thickness of the sliding open area of the sliding roll device, reduce the weight of the sliding open area, and improve the user's use experience has become a problem to be solved in the current field.

[0051] Therefore, the present disclosure provides a sliding roll device, Fig. 1 shows a structural schematic diagram of a sliding roll device in a tightening state according to an embodiment of the present disclosure, and Fig. 2 shows a structural schematic diagram of a sliding roll device in an unfolded state according to an embodiment of the present disclosure, as shown in Figs. 1 and 2, the sliding roll device includes a tightening state 101 and an unfolded state 102. Fig. 3 shows an exploded schematic diagram of various structures in a display device according to an embodiment of the present disclosure, as shown in Fig. 3, the sliding roll device includes: a fixed middle frame 11, which is used as a skeleton support structure of the sliding roll device; a flexible display module 12, which includes a first part 121 and a second part 122 connected to each other, the second part 122 is arranged on a side of the fixed middle frame 11 close to the display side, and the first part 121 is configured to be bent away from the display side of the fixed middle frame 11 to realize switching between the unfolded state and the tightening state.

[0052] It should be noted that the display side mentioned in the embodiments of the present disclosure refers to a plane on which the second part 122 of the flexible display module 12 faces away from the side surface of the fixed middle frame 11, and the display area corresponding to the flexible display module 12 on the plane, which is used to display the display screen of the display device.

[0053] In the embodiments of the present disclosure, the fixed middle frame 11 includes a bottom plate and side plates respectively arranged on the first side, the second side, the third side and the fourth side of the bottom plate, wherein the side plates of the first side and the second side are arranged opposite to each other, the side plates of the third side and the fourth side are arranged opposite to each other, the side plates of the first side and the second side extend along a first direction F1, and the side plates of the third side and the fourth side are respectively arranged between the side plates of the first side and the second side, and the first direction F1 is the unfolding and rolling direction of the slide roller device.

[0054] In some optional embodiments, the third side is a side facing away from the unfolding direction of the flexible display module 12 in the first direction F1, the fourth side is a side facing toward the unfolding direction of the flexible display module 12 in the first direction F1, and the side plate of the third side is configured as a shaft type structure, the first part 121 of the flexible display module 12 slides through the shaft type structure of the fixed middle frame 11 on the third side, realizes the bending of the first part 121 to the side of the fixed middle frame 11 away from the display side, and further realizes the switching between the unfolded state and the rolled state. Specifically, in the process of switching the slide roller device from the rolled state to the unfolded state, the first part 121 slides to the side of the fixed middle frame 11 close to the display side, that is, the area of the first part 121 close to the display side gradually increases, and the area of the first part 121 away from the display side gradually decreases. In the process of switching the slide roller device from the rolled state to the unfolded state, since the second part 122 is connected to the first part 121, on the side of the fixed middle frame 11 close to the display side, the second part 122 is arranged on the side of the first part 121 close to the unfolding direction of the flexible display module 12, therefore, under the sliding action of the first part 121, the second part 122 gradually slides away from the side of the fixed middle frame 11, thereby realizing the unfolding of the flexible display module 12.

[0055] In contrast, during the switching of the sliding and rolling device from the unfolded state to the tightened state, the first part 121 slides away from the side of the fixed middle frame 11 close to the display side, that is, the area of the first part 121 away from the display side gradually increases, and the area of the first part 121 close to the display side gradually decreases. During the switching of the sliding and rolling device from the unfolded state to the tightened state, the second part 122 gradually slides towards the side of the fixed middle frame 11 close to the display side under the sliding action of the first part 121, thereby realizing the tightening of the flexible display module 12.

[0056] In the embodiments of the present disclosure, during the switching of the sliding and rolling device from the tightened state to the unfolded state, the second part 122 of the flexible display module 12 is configured to slide relative to the fixed middle frame 11, and the first part 121 is configured to gradually increase the orthographic projection area of the side of the fixed middle frame 11 close to the display side, thereby gradually increasing the display area of the display side of the flexible display module 12 (including the area of the second part 122 and the area of the first part 121 on the side of the fixed middle frame 11 close to the display side).

[0057] In the sliding process of the second part 122, the area of the second part 122 that is misaligned with the fixed middle frame 11 gradually increases, and the second part 122 gradually loses the support of the fixed middle frame 11, thereby causing a certain support burden to the user and affecting the use experience. In the unfolded state, the orthographic projection of the fixed middle frame 11 on the flexible display module 12 does not overlap the second part 122. Therefore, in order to reduce the weight burden of the second part 122, it is necessary to reduce the thickness of the slide roll device in the corresponding area of the second part 122 and reduce the weight of the slide roll device in the corresponding area of the second part 122 to improve the user experience. In the embodiment of the present disclosure, the flexible display module 12 and the fixed middle frame 11 enclose an accommodation space, and the system component 13 is arranged in the accommodation space. The system component 13 is a key component for realizing the display function in the slide roll device. Since the system component 13 has a large weight and thickness, if the system component 13 is arranged on the second part 122 of the flexible display module 12, it will greatly increase the thickness of the slide roll device in the corresponding area of the second part 122, and further increase the weight of the slide roll device in the corresponding area of the second part 122. Figure 5 shows a top view of an embodiment of the present disclosure, in which a system component is arranged in the accommodation space of the fixed middle frame. As shown in Figure 5, by arranging the system component in the accommodation space, the system component 13 is always in the accommodation space of the fixed middle frame 11 during the conversion of the slide roll device between the tightened state and the unfolded state. The system component 13 is at least partially misaligned with the second part 122, and the system component 13 does not change position with the sliding of the second part 122, so that it always receives the support of the fixed middle frame 11, thereby effectively reducing the thickness of the corresponding slide opening area of the second part 122, reducing the weight of the slide opening area, and improving the user experience.

[0058] In some optional embodiments, during the switching of the sliding and rolling device from the tightening state to the unfolding state, the second part 122 gradually slides away from the side of the fixed middle frame 11 under the sliding action of the first part 121, and the system component 13 is arranged in the accommodating space in the fixed middle frame 11, so that the overlapping area between the orthogonal projection of the system component 13 on the flexible display module 12 and the second part gradually decreases. In the case where the sliding and rolling device is completely switched to the unfolding state, the second part 122 completely slides out of the corresponding area of the fixed middle frame 11, at this time, the orthogonal projection of the system component 13 in the fixed middle frame 11 on the flexible display module 12 has no overlap with the second part 122, the thickness of the corresponding area of the second part 122 is the thickness of the flexible display module 12, and the thickness of the corresponding area of the first part 121 includes the thickness of the flexible display module and the system component 13, so as to ensure that the thickness and counterweight of the corresponding area of the second part 122 suspended outside the fixed middle frame 11 in the unfolding state are small. Since the sliding and rolling device is in the unfolding state most of the time during use, the embodiment of the present disclosure effectively reduces the thickness of the corresponding area of the second part 122 in the unfolding state by arranging the second part 122 and the system component 13 to be completely staggered in the unfolding state, reduces the support requirement of the sliding and rolling device in the unfolding state, and greatly improves the user experience when using the sliding and rolling device.

[0059] In some optional embodiments, the system component 13 includes but is not limited to a battery, a mainboard, a driving board, a loudspeaker, a flexible printed circuit (FPC) component, and the like. It should be noted that the arrangement mode of the system component 13 can be determined according to the actual requirement of the sliding and rolling device, and the composition of the system component 13 can also be determined according to the actual requirement of the sliding and rolling device, which is not limited in the embodiment of the present disclosure.

[0060] In some optional embodiments, as shown in FIG. 3, the system component 13 includes a mainboard 131 and a battery 132. In order to further improve the display performance of the display device, the mainboard 131 and the battery 132 are arranged in a stacked manner along a second direction F2, which is the arrangement direction of the fixed middle frame 11 and the flexible display module 12. In the embodiment of the present disclosure, by arranging the mainboard 131 and the battery 132 of the system component 13 in a stacked manner, the mainboard 131 and the battery 132 avoid mutual restriction of available space due to same-layer arrangement, so that the area of the mainboard 131 and the battery 132 can be maximized without affecting the available space of each other, thereby effectively improving the performance of the system component 13.

[0061] In some optional embodiments, the flexible display module 12 further comprises a module circuit component 123, which comprises components for realizing the display function of the flexible display module 12. Optionally, the module circuit component 123 comprises, but is not limited to, a chip on film (COF), a flexible printed circuit (FPC), a printed circuit board (PCB), and the like. During the operation of the slide roller device, the heat of the slide roller device is mainly generated by the system component 13 of the slide roller device and the module circuit component 123 of the flexible display module 12. If the system component 13 of the slide roller device and the module circuit component 123 of the flexible display module 12 are close to each other during the process of switching the slide roller device from the retracted state to the unfolded state, the heat generated by the operation of the flexible display module 12 and the heat generated by the operation of the system component 13 of the slide roller device will be in the same area, thereby causing the heat generated by the whole slide roller device to be relatively concentrated, resulting in serious local heating of the slide roller device. Therefore, in the embodiments of the present disclosure, FIG. 4 shows a schematic diagram of the combination of the second part of a flexible display module and a movable housing according to an embodiment of the present disclosure. As shown in FIG. 4, the module circuit component 123 is arranged on the side surface of the second part 122 close to the fixed middle frame 11, and the orthographic projection of the module circuit component 123 on the flexible display module 12 is located inside the second part 122. During the process of switching the slide roller device from the retracted state to the unfolded state, the second part 122 and the system component 13 are at least partially arranged in a staggered manner, and the orthographic projection of the module circuit component 123 on the flexible display module 12 is located inside the second part 122, so that the system component 13 and the module circuit component 123 are at least partially arranged in a staggered manner.

[0062] Specifically, during the process of switching the slide roller device from the retracted state to the unfolded state, the overlapping area of the orthographic projection of the system component 13 on the flexible display module 12 and the module circuit component 123 gradually decreases, and in the unfolded state, the orthographic projection of the system component 13 on the flexible display module 12 and the module circuit component 123 have no overlap.

[0063] In the embodiment of the present disclosure, by arranging the module circuit component 123 of the flexible display module 12 on the side surface of the second part 122 close to the fixed middle frame 11, the module circuit component 123 is synchronously slid with the second part 122, and in the process of switching the slide roll device from the tightening state to the unfolded state, the overlapping area between the module circuit component 123 arranged in the area of the second part 122 and the system component 13 arranged in the area of the fixed middle frame 11 gradually decreases, thereby effectively reducing the overlapping area of the heat source, avoiding the concentration of the main heat source in the working process of the slide roll device, and preventing the problem of serious local heating. In addition, since the module circuit component 123 is always located in the area of the second part 122, the module circuit component 123 will not be bent with the first part 121 in the process of switching between the tightening state and the unfolded state, further ensuring that the performance of the module circuit component 123 is not affected by bending.

[0064] In some optional embodiments, the flexible display module 12 can be an organic light emitting diode (OLED) display module, a quantum dot light emitting diode (QLED) display module, etc., which is not limited in the embodiment of the present disclosure.

[0065] In some optional embodiments, as shown in FIGS. 3 and 4, the slide roll device further includes a movable shell 14 arranged on the side surface of the second part close to the fixed middle frame and slidably connected with the fixed middle frame in the first direction F1. In the slide roll device, the movable shell 14 drives the winding and unfolding of the flexible display module 12 by sliding relative to the fixed middle frame 11, thereby realizing the switching of the slide roll device between the unfolded state and the tightening state. In addition, the movable shell 14 also plays a role in sealing and preventing external static electricity from entering. Specifically, the movable shell 14 includes a main body part 141 and a guide part 142, and the guide part 142 extends along the first direction F1 and is located on the opposite sides of the main body part 141. The main body part 141 is arranged protruding away from the display side relative to the guide part 142, so that the side surface of the main body part 141 away from the flexible display module 12 forms a step with the side surface of the guide part 142 away from the flexible display module 12. By arranging the guide part 142 closer to the flexible display module 12 relative to the main body part 141, a structure matching the fixed middle frame 11 is formed, thereby realizing the sliding connection between the movable shell 14 and the fixed middle frame 11.

[0066] In some optional embodiments, FIG. 9 shows a schematic view of the sliding connection between the movable shell and the fixed middle frame of the sliding scroll device in the unfolded state, and FIG. 10 shows a partial enlarged schematic view of the sliding connection between the movable shell and the fixed middle frame of the sliding scroll device in the unfolded state. As shown in FIGS. 9 and 10, the fixed middle frame 11 is provided with a guide strip 111 matching the guide portion 142 of the movable shell 14 on the side close to the flexible display module 12, and the guide strip 111 and the guide portion 142 are slidably connected in the first direction F1. Specifically, the guide strip 111 is arranged on the side of the fixed middle frame 11 located between the first side and the second side and close to the display side, and the guide portion 142 of the movable shell 14 is arranged corresponding to the guide strip 111. The height difference between the side surface of the main body portion 141 away from the flexible display module 12 and the side surface of the guide portion 142 away from the flexible display module 12 is equal to the thickness of the guide strip 111 in the second direction F2. The guide strip limits the sliding of the guide portion 142 in the third direction F3 during the sliding process, so that the guide portion 142 only slides in the first direction F1, thereby realizing the conversion between the retracted state and the unfolded state. The third direction F3 is perpendicular to the first direction F1 and the second direction F2.

[0067] In some optional embodiments, the length of the movable shell 14 in the first direction F1 is greater than the length of the second portion 122 in the first direction F1, so that when the sliding scroll device is completely in the unfolded state, the guide portion 142 of the movable shell 14 and the guide strip 111 of the fixed middle frame 11 have an overlap in the orthographic projection on the flexible display module 12, and there is still a certain overlap length between the guide portion 142 of the movable shell 14 and the guide strip 111 of the fixed middle frame 11. Therefore, the disconnection between the guide strip 111 of the fixed middle frame 11 and the guide portion 142 of the movable shell 14 caused by complete unfolding is avoided, and the problem of jamming or even inability to retract when the sliding scroll device is converted from the unfolded state to the retracted state is avoided.

[0068] In some optional embodiments, since the movable shell 14 is arranged on the surface of the second part 122 away from the display side, there is still an overlapping part between the second part 122 and the fixed middle frame 11 when the second part 122 has not been completely converted to the unfolded state. At this time, in order to reduce the resistance between the one side of the main body part 141 of the movable shell 14 away from the display side and the system components 13 accommodated in the fixed middle frame 11 close to the display side during sliding, the one side of the main body part 141 away from the display side is a flat surface. Arranging the one side of the main body part 141 away from the display side as a flat surface can ensure that the one side of the movable shell away from the display side is aesthetically pleasing while effectively avoiding injury caused by knocking against the user in the unfolded state. In addition, as shown in FIG. 3, since the module circuit part 123 is further arranged between the movable shell 14 and the second part 122, the one side of the main body part 141 close to the display side is provided with an accommodation groove 1411 configured to accommodate the module circuit part 123 of the flexible display module 12.
