In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are a subset of the embodiments in the present application and not all embodiments in the present application. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 2 to 20, in a first aspect, an embodiment of the present application provides a rollable display module 100, which includes a display area 104 and a peripheral area 105 surrounding the display area.

The rollable display module 100 includes a flexible display panel 110, and at least a portion of the flexible display panel 110 is located in the display area 104 of the rollable display module 100.

It is understood that the display area 104 of the rollable display module 100 includes at least a portion of the flexible display panel 110, which can be used for emitting light and displaying images. The peripheral region 105 of the rollable display module 100 can include a portion of the flexible display panel 110 extending to the peripheral region, and the peripheral region 105 can be used for routing the flexible display panel 110.

Referring to fig. 2-4, the y direction is a rolling direction of the rollable display module 100, and the rollable display module 100 in this embodiment can be rolled in a length direction thereof, so that the rolling direction is the length direction of the rollable display module 100. The x direction may be a width direction of the rollable display module 100. The z direction may be a thickness direction of the rollable display module 100.

As shown in fig. 2 and fig. 11 to 19, the flexible display panel 110 includes a flexible panel 112, a functional layer 113, and an encapsulation layer 115, which are stacked in a thickness direction z.

The flexible screen 112 includes a substrate, a driving array layer, and an organic electroluminescent assembly layer, which are stacked. The substrate is located on the side of the flexible screen 112 remote from the thin film encapsulation layer. In the flexible panel 112 located in the display area, the driving array layer includes thin film transistors driving the organic electroluminescent device layer. The organic electroluminescent assembly layer comprises an anode layer, a hole transport layer, a hole injection layer, an organic light emitting layer, an electron injection layer, an electron transport layer, a cathode layer and the like which are sequentially stacked. The thin film transistor is connected with the anode layer or the cathode layer and provides an electric signal for the organic electroluminescent component layer. When electric signals are written in the organic electroluminescent assembly layer, holes of the anode layer are transmitted to the organic light-emitting layer through the hole transmission layer and the hole injection layer, electrons of the cathode layer are transmitted to the organic light-emitting layer through the electron transmission layer and the electron injection layer, and the electrons and the holes are combined in the organic light-emitting layer to generate photoelectrons, so that the organic light-emitting layer emits light.

The flexible screen 112 in the peripheral region is provided with various circuits such as a power supply line, a clock line, a gate driving circuit and a source driving circuit for connecting the thin film transistor, and the like, so as to ensure the normal operation of the flexible display panel.

A thin film encapsulation layer may be further disposed between the flexible screen 112 and the functional layer, and the thin film encapsulation layer is used for encapsulating the flexible screen 112 and may include an organic layer and an inorganic layer which are stacked. The film encapsulation layer can prevent water vapor and oxygen outside the film encapsulation layer from permeating into the flexible screen 112, and ensure the structural stability and the service life of the driving array layer and the organic electroluminescent component layer.

Among them, the functional layer 113 may include a polarizing layer, a touch module layer, and the like. The polarizer is used to transmit light vibrating in a certain direction, and can improve the display contrast of the flexible screen 112. The touch module layer is provided with a plurality of touch elements which are arranged in an array mode so as to realize the touch function of the display panel.

The flexible display panel 110 may further include a first adhesive layer 114, which may be located between the functional layer 113 and the encapsulation layer 115. The first adhesive layer 114 includes an optical glue layer for connecting the functional layer and the encapsulation layer.

Among other things, the encapsulation layer 115 includes a flexible cover sheet having good abrasion and scratch resistance, which can provide flexible protection for the functional layer and the flexible screen 112.

Based on the structure of the flexible display panel 110, the surface of the flexible display panel 110 includes the light emitting surface 117 and the backlight surface 118 spaced apart from each other in the thickness direction z of the flexible display panel 110, and the side surface 119 extending in the thickness direction z of the flexible display panel 110.

In some embodiments, as shown in fig. 2, a surface of the side of the encapsulation layer 115 away from the flexible screen 112 forms a light-emitting surface 117 of the flexible display panel, and a surface of the side of the substrate of the flexible screen 112 away from the encapsulation layer 115 forms a backlight surface 118 of the flexible display panel. In other embodiments, as shown in fig. 11, to further prevent the flexible screen 112 from being damaged, a support protective layer 116 is further adhered to the substrate side of the flexible screen 112 away from the functional layer. At this time, a surface of the side of the support protection layer 116 away from the encapsulation layer 115 forms a backlight surface 118 of the flexible display panel 110.

A side 119 of the flexible display panel is connected between the light emitting surface 117 and the backlight surface 118, and in this embodiment, the flexible screen 112, the functional layer 113, and the encapsulation layer 115 are flush with the side 119. In other embodiments, flexible screen 112, functional layer 113, and encapsulation layer 115 may be non-flush with each other.

In this embodiment, the flexible display panel 110 is connected with a supporting member 120, at least a portion of the supporting member 120 is located in the peripheral region 105 of the rollable display module 100 extending along the rolling direction y, and the supporting member 120 has a supporting end 106.

When the rollable display module 100 is rolled at least two times, the support end 106 of the support 120 of the rollable display module 100 of any one turn abuts against the supported portion 107 of the rollable display module 100 of the adjacent turn, and there is a gap between the flexible display panel 110 of the rollable display module 100 of any one turn and the flexible display panel 110 of the rollable display module 100 of the adjacent turn.

Thus, when the rollable display module 100 is rolled, by the matching of the supporting end 106 of the side surface 119 of the flexible display panel 110 in the peripheral area 105 and the supported portion 107, a distance is formed between two adjacent circles of flexible display panels 110, so that friction between two adjacent circles of flexible display panels 110 is avoided, friction damage to the flexible display panels 110 is prevented, and the service lives of the flexible display panels 110 and the rollable display module 100 with the flexible display panels 110 are prolonged.

As an implementation manner, a distance between the flexible display panel 110 of the rollable display module of any one turn and the flexible display panel 110 of the rollable display module of the adjacent turn ranges from 0.1mm to 3 mm.

When the distance between the flexible display panel 110 of the rollable display module of any circle and the flexible display panel 110 of the rollable display module of the adjacent circle is smaller than 0.1mm, friction may still be generated between the adjacent flexible display panels, resulting in friction damage. When the distance between the flexible display panel 110 of the rollable display module of any circle and the flexible display panel 110 of the rollable display module of the adjacent circle is larger than 3mm, the distance between the adjacent flexible display panels is too large, and the volume of the rollable display module after being rolled is increased without being changed in carrying. Therefore, in practical use, the distance value is adjusted according to practical needs, and the embodiment does not limit this.

In this embodiment, the structure of the supporting member may include the following three types:

in the structural embodiment as the first realizable support, the support 120 includes the first support portion 121 and the second support portion 122.

The first supporting portion 121 is connected to the flexible display panel 110, and at least a portion of the first supporting portion 121 extends into the peripheral region 105 outside the side 119, and the second supporting portion 122 is connected to the first supporting portion 121 in the peripheral region 105 outside the side 119; the end of the second support part 122 forms a support end 106, and the surface of the first support part 121 facing away from the second support part 122 forms a supported part 107.

Thus, when the rollable display module 100 is rolled, due to the matching of the supporting end 106 of the second supporting portion 122 and the supported portion 107 of the first supporting portion 121 in the peripheral region, a distance can be formed between two adjacent circles of flexible display panels 110, friction between two adjacent circles of flexible display panels 110 is avoided, friction damage to the flexible display panels 110 is prevented, and the service lives of the flexible display panels 110 and the rollable display module 100 with the flexible display panels 110 are prolonged.

The support member 120 is divided into a first support portion 121 and a second support portion 122, and the second support portion 122 is connected to the flexible display panel 110 through the first support portion 121, so that stability of a connection relationship between the second support portion 122 and the flexible display panel 110 is increased. The first supporting part 121 is disposed to improve the supporting strength of the flexible display panel 110.

Specifically, the embodiments of the connection of the first support portion 121 and the second support portion 122 include the following two types:

referring to fig. 2 to 10, in a first possible embodiment of connecting the first supporting portion and the second supporting portion, the first supporting portion 121 is connected to the backlight surface 118 of the flexible display panel 110 in the peripheral region 105, the second supporting portion 122 is located on a side of the first supporting portion 121 close to the light emitting surface 117, an end of the second supporting portion 122 extends toward the light emitting surface 117, and an end of the second supporting portion 122 is higher than the light emitting surface 117.

It can be realized that a second adhesive layer 111 can be arranged between the first supporting part and the backlight surface, the first supporting part 121 is connected with the backlight surface 118 through the second adhesive layer 111, and the second adhesive layer 111 can select optical cement.

The second support part 122 is located in the peripheral area 105 outside the side surface of the flexible display panel 110, and may extend in the rolling direction y. The second support portion 122 is connected to a side of the first support portion 121 close to the light emitting surface 117. The second supporting portion 122 is connected to the first supporting portion 121 by a second connecting member 1212, and the second connecting member 1212 may be a double-sided tape. The end of the second supporting portion 122 is higher than the light emitting surface 117, and it can be understood that the end of the second supporting portion protrudes out of the light emitting surface 117.

In some embodiments, as shown in fig. 2 and 3, the first supporting portion 121 is disposed in a whole layer, a surface of the first supporting portion 121 close to the backlight surface 118 is connected to the entire backlight surface 118, and the first supporting portion 121 extends into the peripheral region 105 outside the side surface of the flexible display panel 110 (i.e., the first supporting portion 121 extends along the width direction x).

As an alternative embodiment, the end of the second supporting portion 122 extends toward the light emitting surface 117 and is higher than the light emitting surface 117 to form the supporting end 106. The distance between the end of the second supporting part 122 and the light-emitting surface 117 is 0.1mm-3 mm.

When the distance between the end portions of the second supporting portions 122 and the light emitting surface 117 is less than 0.1mm, the end portions of the second supporting portions 122 are not enough to form the supporting ends 106, and friction may still occur between adjacent flexible display panels, which may cause friction damage. When the distance between the end portions of the second supporting portions 122 and the light emitting surface 117 is greater than 3mm, the supporting ends 106 formed by the end portions of the second supporting portions 122 are too convex, which affects the visual effect of the display area, and the distance between the adjacent flexible display panels is too large, so that the curled display module after being curled is increased in volume and is not changed in carrying. Therefore, in practical use, the distance value is adjusted according to practical needs, and the embodiment does not limit this.

As an alternative embodiment, the second supporting portion 122 is spaced apart from the side 119 of the flexible display panel 110 by a distance in a range of 0.1mm to 1 mm. An adhesive 1222 is filled between the second support portion 122 and the side surface 119, and the adhesive 1222 connects the second support portion 122 and the side surface 119. The Adhesive 1222 may be selected from UV glue (Ultraviolet light Adhesive).

When the distance between the second supporting portion 122 and the side surface of the flexible display panel 110 is smaller than 0.1mm, the adhesive member filled in the distance between the second supporting portion 122 and the side surface of the flexible display panel 110 is not enough to enable the second supporting portion and the flexible display panel to be fastened and connected, the second supporting portion and the flexible display panel are likely to be separated in the winding use process, the display module 100 capable of being curled is damaged, and the service life of the display module 100 capable of being curled is shortened. When the distance between the second supporting portion 122 and the side surface of the flexible display panel 110 is greater than 1mm, the space occupied by the bonding member in the rollable display module 100 is increased, the occupied space of the flexible display panel is reduced, and the area of the display area is reduced. Therefore, in practical use, the distance value is adjusted according to practical needs, and the embodiment does not limit this.

Fig. 5-10 illustrate the basic process of making the rollable display module 100. First, the first support part 121 shown in fig. 5 and 6 is manufactured. Then, as shown in fig. 7 and 8, the second support part 122 is bonded to the first support part 121. Next, as shown in fig. 9 and 10, a second adhesive layer 111 is applied to the surface of the first support section 121, and the flexible display panel 110 is adhered to the first support section 121 via the second adhesive layer 111. Finally, an adhesive 1222 is filled between the second supporting portion 122 and the side 119 of the flexible display panel 110, so as to form the rollable display module 100 shown in fig. 2.

As shown in fig. 4, where d denotes a distance between the flexible display panels of two adjacent circles, k denotes a distance between an end of the second supporting portion and the light exit surface, and n denotes a distance between the second supporting portion and the side surface of the flexible display panel. After the rollable display module 100 is rolled at least two times, the support end 106 of the second support portion 122 of the second rollable display module 102 abuts against the supported portion 107 of the first support portion 121 of the first rollable display module 101, the support end 106 of the second support portion 122 of the third rollable display module 103 abuts against the supported portion 107 of the first support portion 121 of the second rollable display module 102, and so on, the support end 106 of the second support portion 122 of any one rollable display module abuts against the supported portion 107 of the first support portion 121 of the adjacent rollable display module, so that a gap is formed between the light-emitting surface 117 of the flexible display panel 110 of the rollable display module of any one turn and the first support portion 121 of the flexible display panel 110 of the adjacent rollable display module.

Thus, the first supporting portion 121 forms the supporting end 106 on the light-emitting surface 117 side, the second supporting portion 122 forms the supported portion 107 on the backlight surface 118 side, and by the cooperation of the supporting end 106 and the supported portion 107, when the rollable display module 110 is wound, a space (the space is formed between the light-emitting surface 117 and the first supporting portion 121 of the adjacent circle) is also formed between the two adjacent circles of flexible display panels 110, so that friction between the two adjacent circles of flexible display panels 110 is avoided, friction damage to the flexible display panels 110 is prevented, and the service lives of the flexible display panels 110 and the rollable display module having the flexible display panels 110 are prolonged.

The first supporting part 121 is connected to the backlight surface 118 of the flexible display panel 110, so that the connection area between the first supporting part 121 and the flexible display panel 110 can be increased, the supporting strength of the flexible display panel 110 is improved, and the uniformity of the distance between two adjacent circles of the flexible display panel 110 after winding is improved.

Referring to fig. 12, in a second possible embodiment of connecting the first supporting portion and the second supporting portion, the first supporting portion 121 is connected to the light emitting surface 117 of the flexible display panel 110 in the peripheral region 105, the second supporting portion 122 is located on a side of the first supporting portion 121 close to the backlight surface 118, an end of the second supporting portion 122 extends toward the backlight surface 118, and an end of the second supporting portion 122 protrudes from the backlight surface 118.

As shown in fig. 12, the first supporting portion 121 is connected to the light emitting surface 117 of the flexible display panel 110 in the peripheral area 105, and extends into the peripheral area 105 outside the side surface of the flexible display panel 110 (i.e., the first supporting portion 121 extends in the width direction x). The second support part 122 is located in the peripheral area 105 outside the side surface of the flexible display panel 110, and may extend in the rolling direction y. The second supporting portion 122 is adhered to one side of the first supporting portion 121 close to the backlight surface. The second supporting portion 122 is spaced apart from the side 119 of the flexible display panel 110, and is connected to an adhesive 1222. The end of the second supporting portion 122 extends toward the backlight surface 118 and protrudes from the backlight surface 118 to form the supporting end 106.

Thus, the second supporting portion 122 forms the supporting end 106 on the backlight surface 118 side, the first supporting portion 121 forms the supported portion 107 on the light emitting surface 117 side, and by the cooperation of the supporting end 106 and the supporting portion 107, when the rollable display module 110 is rolled, a space is formed between two adjacent circles of the flexible display panels 110 (the space is formed between the backlight surface 118 and the light emitting surface 117 of the adjacent circle), which avoids friction between two adjacent circles of the flexible display panels 110, avoids friction damage to the flexible display panels 110, and prolongs the service life of the flexible display panels 110 and the rollable display module 100 having the flexible display panels 110.

In the above two possible embodiments of connecting the first supporting portion and the second supporting portion, the first supporting portion 121 and the second supporting portion 122 may be formed integrally.

The first supporting portion 121 may be made of a steel sheet, the second supporting portion 122 may be made of a resin, for example, a profiled high-elasticity wear-resistant rubber, and the first supporting portion 121 and the second supporting portion 122 are integrally formed through a vulcanization process. The first supporting portion 121 and the second supporting portion 122 may be made of resin, and both may be integrally formed by plastic injection molding. The first supporting part 121 and the second supporting part 122 are integrally formed, so that the strength and the stability of the structure are further improved.

In the first structural embodiment of the support member, the second support part 122 of the support member 120 is connected to the flexible display panel 110 through the first support part 121, and the first support part 110 improves the support strength of the flexible display panel.

As a second possible structural embodiment of the supporting member, the supporting member 120 is connected to the flexible display panel 110 located in the peripheral region 105, and the following four embodiments may be included:

in a first possible embodiment, the support 120 is connected to the light exit surface 117.

Referring to fig. 14, the supporting member 120 is connected to the light-emitting surface 117 of the flexible display panel 110 in the peripheral region 105, the supporting end 106 is higher than the light-emitting surface 117, and the backlight surface 118 of the flexible display panel 110 in the peripheral region 105 forms a supported portion.

Thus, the supporting end is formed at the side of the light-emitting surface 117 located in the peripheral area 105, the backlight surface 118 located in the peripheral area 105 forms a supported portion, and through the matching between the supporting end and the supported portion, when the rollable display module 110 is rolled, a space is formed between two adjacent circles of the flexible display panels 110 (the space is formed between the light-emitting surface 117 and the adjacent circle of the backlight surface 118), thereby avoiding the friction between two adjacent circles of the flexible display panels 110, preventing the flexible display panels 110 from being damaged by the friction, and prolonging the service life of the flexible display panels 110 and the rollable display module 100 having the flexible display panels 110.

The support member 120 is connected to the flexible display panel 110, and occupies a smaller connection area, and the same size of the rollable display module 100 can provide a display area with a larger area. The supporting member 120 is located in the peripheral region 105, and does not affect the display screen of the flexible display panel.

In a second possible embodiment, the support 120 is attached to the backlight surface 118.

Referring to fig. 15, the supporting member 120 is connected to the backlight surface 118 of the flexible display panel 110 in the peripheral region 105, the supporting end 106 protrudes out of the backlight surface 118, and the light-emitting surface 117 of the flexible display panel 110 in the peripheral region 105 forms the supported portion 107.

In this embodiment, as shown in fig. 15, the supporting element 120 is connected to the backlight surface 118 of the flexible display panel 110 in the peripheral region 105, and the supporting element 120 protrudes from the backlight surface 118 and forms the supporting end 106. In other embodiments, the support 120 may be attached to the entire backlight surface 118 of the flexible display panel 110.

In this way, the supporting end 106 is formed on one side of the backlight surface 118, the light emitting surface 117 located in the peripheral area 105 forms the supported portion 107, and by the cooperation of the supporting end 106 and the supported portion 107, when the rollable display module 110 is rolled up, a space (formed between the light emitting surface 117 and the backlight surface 118 of the adjacent circle) is also formed between the two adjacent circles of flexible display panels 110, so that friction between the two adjacent circles of flexible display panels 110 is avoided, friction damage to the flexible display panels 110 is prevented, and the service lives of the flexible display panels 110 and the rollable display module 100 having the flexible display panels 110 are prolonged.

The support 120 is connected to the backlight surface 118, so that the display area 104 is not shielded, and the visual experience of the flexible line panel is improved. In some embodiments, when the support 120 supports the entire backlight surface 118, the support strength of the flexible display panel 110 can be enhanced, and the uniformity of the spacing between two adjacent turns of the flexible display panel 110 after winding is improved.

In a third possible embodiment, the support 120 is connected between the light emitting surface 117 and the backlight surface 118.

Referring to fig. 16 and 17, the support member 120 includes a first sub-support member 1201 and a second sub-support member 1202, the first sub-support member 1201 is connected to the light emitting surface 117 of the flexible display panel 110 located in the peripheral region 105, the second sub-support member 1202 is connected to the backlight surface 118 of the flexible display panel 110 located in the peripheral region 105, and the first sub-support member 1201 and the second sub-support member 1202 are disposed opposite to each other; the supporting end 106 is located on one of the first and second sub-supports 1201 and 1202, and the supported portion 107 is located on the other of the first and second sub-supports 1201 and 1202.

The first sub-supporting member 1201 is connected to the light emitting surface 117, and the second sub-supporting member 1202 may be connected to the backlight surface 118 of the flexible display panel 110 in the peripheral region 105 as shown in fig. 16, or connected to the entire backlight surface 118 of the flexible display panel 110 as shown in fig. 17. One of the first sub-support 1201 and the second sub-support 1202 may be higher than the connection surface thereof, or both the first sub-support 1201 and the second sub-support 1202 are higher than the connection surface thereof, or the first sub-support 1201 is higher than the light-emitting surface 117, and the second sub-support 1202 is recessed toward the direction close to the light-emitting surface 117, or the first sub-support 1201 may be recessed toward the backlight surface 118, and the second sub-support 1202 is higher than the backlight surface 118, so that the first sub-support 1201 and the second sub-support 1202 are matched with each other, one of them forms the support end 106, and the other forms the supported portion 107, so that after the rollable display module 100 is rolled, the support end 106 is matched with the supported portion 107, and supports the flexible display panels 110 of adjacent ring layers, and ensures that a space is formed between the flexible display panels 110 of adjacent rings.

In this way, one of the first sub-supporting member 1201 and the second sub-supporting member 1202 forms the supporting end 106, and the other one of the first sub-supporting member 1201 and the second sub-supporting member 1202 forms the supported portion 107, and by the cooperation between the supporting end 106 and the supported portion 107, when the rollable display module 110 is rolled up, a space (formed between the light emitting surface 117 and the backlight surface 118 of the adjacent circle) is also provided between the two adjacent circles of flexible display panels 110, so that friction between the two adjacent circles of flexible display panels 110 is avoided, friction damage to the flexible display panels 110 is not caused, and the service lives of the flexible display panels 110 and the rollable display module 100 having the flexible display panels 110 are prolonged.

The supporting member 120 is divided into a first sub-supporting member 1201 and a second sub-supporting member 1202, which are respectively connected to the light emitting surface 117 and the backlight surface 118, and the distance between the first sub-supporting member 1201 and the second sub-supporting member 1202 and the connection surface can be properly adjusted as required, so as to facilitate the structural adjustment by matching with the rollable display module 100.

In a fourth possible embodiment, the support member 120 is connected to only the side of the flexible display panel 110.

Referring to fig. 13, a support 120 is connected to a side 119 of the flexible display panel 110 in the peripheral region 105, one of an end of the support 120 close to the light-emitting surface 117 and an end of the support 120 close to the backlight surface 118 forms a supporting end 106, the other of the end of the support 120 close to the light-emitting surface 117 and the end of the support 120 close to the backlight surface 118 forms a supported portion 107.

In the present embodiment, as shown in fig. 13, an end of the supporting member 120 close to the light emitting surface 117 is higher than the light emitting surface to form the supporting end 106. The end of the support 120 near the backlight surface 118 forms a supported portion 107. In other embodiments, the end of the support 120 near the backlight surface 118 may extend beyond the backlight surface 118 to form the support end 106. An end of the support 120 near the light emitting surface 117 may form a supported portion 107. Reference may also be made to the arrangement of the first sub-support 1201 and the second sub-support 1202, wherein one end of the first sub-support is higher than the backlight surface, and the other end of the first sub-support is recessed. The above arrangement is based on the design distance formed between the two adjacent circles of the flexible display panel 110.

In this way, the supporting end 106 and the supported portion 107 are formed on the side surface of the flexible display panel by the supporting member 120, and similarly, when the rollable display module 110 is rolled, a space (the space is formed between the light emitting surface 117 and the backlight surface 118 of the adjacent circle) is formed between two adjacent circles of flexible display panels 110, so that friction between two adjacent circles of flexible display panels 110 is avoided, friction damage to the flexible display panels 110 is avoided, and the service lives of the flexible display panels 110 and the rollable display module 100 having the flexible display panels 110 are prolonged.

The supporting end 106 is formed outside the flexible display panel 110, so as to avoid covering the light emitting surface 117 and the backlight surface 118 of the flexible display panel 110, and the visual effect of the display area of the flexible display panel 110 is not affected.

In the above four possible embodiments, the optional supporting element 120 is integrally formed on the connecting surface thereof, for example, the supporting element 120 and the backlight surface 118 are integrally formed on the layer, so as to further improve the connection stability of the structure.

In this second possible structural implementation of the supporting member, the supporting member 120 is directly connected to the flexible display panel 110 in the peripheral region 105, so that the connection relationship is simple and the manufacturing process is simple.

In a third possible embodiment of the support structure, the support 120 is a combination of the two possible embodiments of the support structure.

As shown in fig. 18 and 19, a support 120 is connected to the light emitting surface 117, the side surface 119, and the backlight surface 118 of the flexible display panel 110, an adhesive 1222 is filled between the support 120 and the side surface 119 of the flexible display panel 110, the support 120 and the light emitting surface 117 are connected by a second adhesive layer 111, and the support 120 and the backlight surface 118 are connected by the second adhesive layer 111. The portion of the support member 120 connected to the backlight surface 118 may extend over the entire backlight surface 118 as shown in fig. 18, or may be connected only to the backlight surface 118 of the flexible display panel 110 located in the peripheral region 105 as shown in fig. 19. In line with the manner of mating the first and second sub-supports 1201 and 1202, the support 120 forms a support end 106 and a supported portion 107, respectively.

Thus, by matching the supporting end 106 and the supported portion 107, when the rollable display module 110 is wound, a space (the space is formed between the light emitting surface 117 and the backlight surface 118 of the adjacent circle) is also formed between the two adjacent circles of flexible display panels 110, so that friction between the two adjacent circles of flexible display panels 110 is avoided, friction damage to the flexible display panels 110 is avoided, and the service lives of the flexible display panels 110 and the rollable display module with the flexible display panels 110 are prolonged.

In one possible implementation, referring to fig. 2 and 3, the support 120 is a flexible member, the support 120 extends along the rolling direction y, and the extension length of the support 120 is equal to or less than the extension length of the rollable display module 100 along the rolling direction y.

As shown in fig. 2-3, the length of the supporting member 120 is equal to the length of the rollable display module 100 along the rolling direction y. Thus, when the rollable display module 100 is rolled, the support member 120 is continuously rolled along with the flexible display panel, so as to form a support for each flexible display panel 110. Alternatively, the support member 120 is a resin member.

Referring to fig. 20, there may be a plurality of the supporting members 120, and the plurality of supporting members 120 are spaced apart from each other in the winding direction y. In this way, the supporting member 120 is supported between two adjacent circles of the flexible display panel 110 at an interval when the rollable display module 100 is rolled. Alternatively, the support member 120 is a rigid member, such as a steel plate.

In an embodiment, as shown in fig. 2, 11-14 and 17-19, a fitting structure is provided at the abutting position of the supporting end 106 and the supported portion 107, the fitting structure includes a fitting groove 1211 and an insert 1221, and the shape of the fitting groove 1211 is matched with the shape of the insert 1221 and is fitted with each other. The insertion groove 1211 is located on one of the supporting end 106 and the supported portion 107, and the insertion piece 1221 is located on the other of the supporting end 106 and the supported portion 107.

Thus, when the rollable display module 100 is rolled, the insert 1221 is inserted into the insertion groove 1211, so as to prevent the flexible display panel 110 from being dislocated, thereby performing a limiting function. As shown in fig. 2, the cross-sections of the insertion groove 1211 and the insertion member 1221 are configured to be matched with each other in a semicircular shape, and the cross-sections of the insertion groove 1211 and the insertion member 1221 may be other shapes such as a square shape and a trapezoid shape.

The groove depth k of the embedded groove ranges from 0.1mm to 1 mm.

When the groove depth k of the embedded groove is less than 0.1mm, the embedded depth of the embedded groove and the embedded part is too small, and the embedding effect cannot be realized. When the depth of the insertion groove is greater than 1mm, it is understood that the insertion groove 1211 is disposed to avoid affecting the flexible display panel 110, and the groove bottom thereof is located at least at the outer side of the layer connecting the flexible display panel 110. The too deep embedded groove is arranged, so that the distance between the supporting piece where the embedded groove is located and the connecting surface of the supporting piece is too large, the thickness of the flexible display device is increased, and the flexible display device is inconvenient to use and carry. Therefore, in practical use, the distance value is adjusted according to practical needs, and the embodiment does not limit this.

The insertion groove 1211 extends along the winding direction y, the extension length of the optional insertion groove 1211 is less than or equal to the extension length of the rollable display module 100 along the winding direction y, and a plurality of insertion grooves 1211 are optionally provided, wherein the insertion grooves 1211 are arranged at intervals along the winding direction y. Of course, the plurality of insertion grooves 1211 may be disposed at intervals along the width direction x perpendicular to the winding direction y, and in practical use, the direction in which the plurality of insertion grooves 1211 are disposed at intervals may be other than the width direction x and the winding direction y, which is not limited in this embodiment. The number of the insertion pieces 1221 is equal to the number of the insertion grooves 1211, and they are provided in one-to-one correspondence.

Thus, the insertion grooves 1211 are continuously or discontinuously distributed on one side of the rollable display module 100, and the corresponding insertion pieces 1221 are continuously or discontinuously distributed on the other side of the rollable display module 100, so as to facilitate the convenience of the winding operation; by increasing the number of the insert members 1221 and the insert grooves 1211, the stability of the winding operation is improved.

Referring to fig. 21, in a second aspect, the present disclosure provides a rollable display device 200, which includes a reel 210 and the rollable display module 100, wherein one end of the rollable display module 100 along the rolling direction y is connected to the reel 210 through a first connection member 211.

When the rollable display device 200 is in the rolled state, there is a gap between the rollable display module 100 and the reel 210.

The display device may be a mobile or fixed terminal such as a mobile phone, a television, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a Personal Digital Assistant (PDA), a virtual reality device, and the like.

The rollable display device 200 provided by the embodiment of the present application includes a reel 210 and a rollable display module 100. When the rollable display device 200 is rolled, due to the arrangement of the first connector 211, a space is reserved between the flexible display panel 110 of the first loop and the reel, and friction between the flexible display panel 110 and the reel 210 is avoided. The rollable display module 100 includes a flexible display panel 110 and a support member 120 connected to each other, at least a portion of the flexible display panel 110 is located in a display area 104 of the rollable display module 100, at least a portion of the support member 120 is located in a peripheral area 105 of the rollable display module 100 extending along a rolling direction y, the support member 120 has a support end 106, and the rollable display module 100 has a supported portion 107. When the rollable display module 100 is rolled at least two times, the support end 106 of the support of the rollable display module of any circle abuts against the supported portion 107 of the rollable display module of the adjacent circle, and there is a gap between the flexible display panel of the rollable display module of any circle and the flexible display panel of the rollable display module of the adjacent circle. Thus, when the rollable display module 100 is rolled, the supporting end 106 and the supported portion 107 are matched to enable a distance to be reserved between two adjacent circles of the flexible display panels 110, so that friction between two adjacent circles of the flexible display panels 110 is avoided, friction damage to the flexible display panels 110 is avoided, and the service lives of the flexible display panels 110, the rollable display module 100 with the flexible display panels 110 and the rollable display device 200 are prolonged.
