[0049] Figure 1 A schematic diagram illustrating the structure of a display device in a folded state, according to an embodiment of this disclosure, is provided. Figure 2 A schematic diagram illustrating the unfolded state of a display device provided in this disclosure is illustrated. Figure 3 A schematic diagram illustrating the structure of a flexible display screen provided in this disclosure is shown. Figure 1 or Figure 2 ,as well as Figure 3 As shown, the display device includes: a display housing 1, a folding mechanism 2, and a flexible display screen 3. The display housing 1 includes a first main housing 11 and a second main housing 12, the width of the first main housing 11 being greater than the width of the second main housing 12. The folding mechanism 2 is located between the first main housing 11 and the second main housing 12, and is connected to one side of the first main housing 11 along the length direction and one side of the second main housing 12 along the length direction, respectively. The first main housing 11 and the second main housing 12 can switch between folding and unfolding. The flexible display screen 3 is connected to the first main housing 11 and the second main housing 12, respectively, and has a binding area 31 located on one side of the first main housing 11 along the length direction.

[0050] In this embodiment, since the width of the first main housing 11 is greater than the width of the second main housing 12, asymmetrical folding of the display device is achieved. Thus, by placing the bonding area 31 of the flexible display screen 3 on one side of the first main housing 11 along its length, the maximum width of the bonding area 31 is greater than half the width of the display device. Compared to symmetrically folded display devices in related technologies (where the maximum width of the bonding area 31 is only half the width of the display device), the display device provided by this embodiment can significantly increase the maximum width of the bonding area 31, thereby reducing wiring difficulty for the bonding area 31 with its maximum width.

[0051] In this context, the widths of the first main housing 11 and the second main housing 12 refer to their dimensions in the vertical length direction. The length direction discussed in this disclosure refers to the length direction of the display device. Figure 1 or Figure 2 The direction shown is O. After the first main housing 11 and the second main housing 12 are connected by the folding mechanism 2, they can switch between folding and unfolding, thereby enabling the display device to have the following... Figure 1 The folded state shown, or as Figure 2 The unfolded state is shown. The specific structure of the folding mechanism 2 can be referenced from related technologies, as long as the surfaces of the first main housing 11 and the second main housing 12 on the same side are coplanar when the display device is in the unfolded state. This embodiment does not limit this. For example, the folding structure is a folding hinge.

[0052] Among them, such as Figure 3 As shown, the flexible display screen 3 has a first display area 32, a second display area 33, and a folding area 34 located between the first display area 32 and the second display area 33. The edge of the first display area 32 is limited to the first main housing 11 so that the orthographic projection of the first display area 32 is located on the first main housing 11. The edge of the second display area 33 is limited to the second main housing 12 so that the orthographic projection of the second display area 33 is located on the second main housing 12. The binding area 31 of the flexible display screen 3 is connected to the first display area 32. When the display device is in a folded state, the first display area 32 and the second display area 33 of the flexible display screen 3 are in a stacked state facing each other; when the display device is in an unfolded state, the first display area 32 and the second display area 33 of the flexible display screen 3 are in a coplanar state.

[0053] When the display device is in a folded state, the first main housing 11 and the second main housing 12 can be folded relative to each other, that is, folded in a way that causes the first display area 32 and the second display area 33 to be opposite each other, in which case the first display area 32 and the second display area 33 are located between the first main housing 11 and the second main housing 12; or they can be folded back to back, that is, folded in a way that causes the first display area 32 and the second display area 33 to be opposite to each other, in which case the first main housing 11 and the second main housing 12 are located between the first display area 32 and the second display area 33.

[0054] When the first main housing 11 and the second main housing 12 are folded relative to each other, because the width of the second main housing 12 is smaller than the width of the first main housing 11, the second main housing 12 fails to completely cover the first display area 32. Therefore, when the display device is in the folded state, as... Figure 1 As shown, the screen ratio of the display device can be increased by displaying the image through the area D on the first display area 32 that is not blocked by the second main housing 12, thereby achieving a certain screen ratio of the display device.

[0055] For the first main housing 11 and the second main housing 12 included in the display housing 1, the larger the ratio of the width of the first main housing 11 to the width of the second main housing 12, the wider the area that the display device can display when it is in the folded state, and the wider the binding area 31 is when the first main housing 11 and the second main housing 12 are folded in a relatively folding manner. However, the width of the second main housing 12 will also be narrower, thus affecting the aesthetics of the display device.

[0056] Optionally, the ratio of the width of the first main housing 11 to the width of the second main housing 12 is 2, that is, the width of the first main housing 11 is twice the width of the second main housing 12. Thus, the width of the second main housing 12 is 1 / 3 of the width of the display device, so as to ensure the aesthetics of the display device when it is folded, and the display device has a wider binding area 31 (2 / 3 of the width of the display device) to reduce the wiring difficulty of the binding area 31; and the display device has a wider display area (1 / 3 of the width of the display device) when it is folded, so as to ensure the display effect of the display device when it is folded.

[0057] Of course, the ratio of the width of the first main housing 11 to the width of the second main housing 12 can also be other values, as long as the display device has a wide binding area 31 and the display device is aesthetically pleasing when folded, and has a wide display area. This disclosure does not limit this.

[0058] In this embodiment, the display device may only have a folded form, or it may have a roll-up form. When the display device has both a folded and a roll-up form, it can achieve multiple screen-to-body ratios in the folded form and at least one screen-to-body ratio in the roll-up state, thereby improving the display effect.

[0059] For the structure of the display device with a folding form, please refer to the above embodiments. Next, the structure of the display device with a sliding form will be explained.

[0060] For a display device with a sliding and retracting shape, the first main housing 11 may have a sliding and retracting state, or the second main housing 12 may have a sliding and retracting state, or both the first main housing 11 and the second main housing 12 may have a sliding and retracting state.

[0061] In cases where both the first main housing 11 and the second main housing 12 have a sliding state and a retracted state, a screen ratio display can be achieved by sliding the first main housing 11 alone, a screen ratio display can be achieved by sliding the second main housing 12 alone, or a screen ratio display can be achieved by sliding the first main housing 11 and the second main housing 12 simultaneously.

[0062] Taking the first main housing 11 having a sliding state and a retracted state as an example, such as Figure 2 or Figure 4 As shown, the first main housing 11 includes a first main housing 111 and a first sliding housing 112. One side of the first main housing 111 along the length direction is connected to the folding mechanism 2. The first sliding housing 112 is connected to the side of the first main housing 111 away from the folding mechanism 2, and the first sliding housing 112 can slide relative to the first main housing 111 in a direction perpendicular to the length direction.

[0063] The first sliding housing 112 is capable of sliding relative to the first main housing 111 in a direction perpendicular to its length, i.e., the first sliding housing 112 can slide away from the first main housing 111, so that the first main housing 11 is in a position such that... Figure 4 The slide-roll state shown, or the sliding towards the first main housing 111, so that the first main housing 11 is in the position shown. Figure 2 The retracted state is shown. In this way, the first main housing 11 can be switched between the sliding state and the retracted state by sliding the first sliding housing 112 relative to the first main housing 111.

[0064] In addition, in the case where the first main housing 11 includes the first main housing 111 and the first sliding housing 112, in order to ensure the normal display of the flexible display screen 3, the flexible display screen 3 is slidably fixed on the first sliding housing 112.

[0065] The flexible display screen 3 includes a bonding area 31 located on one side of the first host housing 111 along the length direction, and the maximum design width of the bonding area 31 is the width of the first host housing 111, so as to ensure that the flexible display screen 3 has a wider width, thereby reducing the wiring difficulty of the bonding area 31.

[0066] Among them, such as Figure 5 As shown, the flexible display screen 3 includes, in addition to the first display area 32, the second display area 33, and the folding area 34 mentioned above, a first sliding area 35; the first display area 32 is limited on the first main housing 111, the second display area 33 is limited on the second main housing 121, and the first sliding area 35 is slidably fixed on the first sliding housing 112.

[0067] Thus, when the first sliding housing 112 moves away from the first main housing 111, the first sliding roll area 35 slides relative to the first sliding housing 112, so that the first sliding roll area 35 is in a flat state and coplanar with the first display area 32, so as to display the image in the first sliding roll area 35, the first display area 32, the second display area 33, and the folding area 34; when the first sliding housing 112 slides towards the first main housing 111, the first sliding roll area 35 slides relative to the first sliding housing 112, so that the first sliding roll area 35 is in a rolled-up state, so as to display the image in the first display area 32, the second display area 33, and the folding area 34. In addition, when the first main housing 11 switches between the sliding state and the retracted state, the display device can switch between two different screen ratios simultaneously, thereby improving the display effect of the display device.

[0068] The connection method between the first sliding area 35 of the flexible display screen 3 and the first sliding housing 112 can refer to related technologies, and this disclosure does not limit this aspect. For example, in some embodiments, such as... Figure 6 As shown, the first sliding housing 112 includes a first frame 1121, a second frame 1122, a side plate 1123, and a plurality of slide rods 1124. The first frame 1121 and the second frame 1122 are arranged opposite to each other, and the side plate 1123 is connected between the first frame 1121 and the second frame 1122. The opposite side walls of the first frame 1121 and the second frame 1122 have slide tracks. The ends of the slide rods 1124 are respectively slidably limited within the slide tracks on the first frame 1121 and the second frame 1122. The first sliding roll area 35 of the flexible display screen 3 is fixed on the plurality of slide rods 1124 (for example, by adhesive bonding).

[0069] Thus, when the first sliding housing 112 slides relative to the first main housing 111, multiple sliders 1124 slide within the tracks of the first frame 1121 and the second frame 1122, thereby enabling the sliding of the first roll-up area 35 of the flexible display screen 3 and ensuring that the display device can switch between two different screen ratios (displaying images through the first display area 32, the second display area 33, and the folding area 34, or displaying images through the first display area 32, the second display area 33, the folding area 34, and the first roll-up area 35).

[0070] In some implementations, such as Figure 6 As shown, the shell wall of the first main housing 111 has a plurality of first comb tooth structures 1111 facing the first sliding housing 112, and the shell wall of the first sliding housing 112 has a plurality of second comb tooth structures 1125 facing the first main housing 111 (for example, the side plate 1123 of the first sliding housing 112 has a second comb tooth structure 1125 facing the first main housing 111), and the plurality of first comb tooth structures 1111 engage with the plurality of second comb tooth structures 1125.

[0071] The plurality of first comb tooth structures 1111 and the plurality of second comb tooth structures 1125 are distributed at intervals along the length direction, and the first comb tooth structures 1111 and the second comb tooth structures 1125 are arranged alternately to facilitate the meshing of the plurality of first comb tooth structures 1111 and the plurality of second comb tooth structures 1125. The first sliding housing 112 slides away from the first main housing 111 so that when the first main housing 111 is in the rolled-up state, at least the tips of the plurality of first comb tooth structures 1111 and the plurality of second comb tooth structures 1125 mesh; the first sliding housing 112 slides towards the first main housing 111 so that when the first main housing 111 is in the retracted state, the plurality of first comb tooth structures 1111 and the plurality of second comb tooth structures 1125 are fully meshed.

[0072] When the first sliding housing 112 slides away from the first main housing 111, a gap will inevitably form between the first sliding housing 112 and the first main housing 111. However, through the above-mentioned arrangement of the first comb tooth structure 1111 and the second comb tooth structure 1125, when the first comb tooth structure 1111 and the second comb tooth structure 1125 are engaged, the gap between the first sliding housing 112 and the first main housing 111 is prevented from penetrating the first main housing 11 in the length direction. This ensures the support effect of the first main housing 11 on the flexible display screen 3 when the first main housing 11 of the display device is in the sliding state. In addition, when the first main housing 11 is in a sliding state, at least the tips of the multiple first comb tooth structures 1111 and the multiple second comb tooth structures 1125 are engaged. In this way, by limiting the middle second comb tooth structure 1125 by two adjacent first comb tooth structures 1111, and by limiting the middle first comb tooth structure 1111 by two adjacent second comb tooth structures 1125, the stability of the first sliding housing 112 sliding towards the first main housing 111 is ensured, and the first sliding housing 112 is prevented from tilting.

[0073] Optionally, such as Figure 6 As shown, the first comb tooth structure 1111 and the second comb tooth structure 1125 are both rectangular. Of course, in this embodiment, the first comb tooth structure 1111 and the second comb tooth structure 1125 can also be triangular or trapezoidal, etc. This embodiment does not limit this.

[0074] When both the first comb tooth structure 1111 and the second comb tooth structure 1125 are rectangular, when the first sliding housing 112 slides relative to the first main housing 111, the side of the first comb tooth structure 1111 along the sliding direction continuously contacts the side of the second comb tooth structure 1125 along the sliding direction, thereby continuously limiting the first sliding housing 112 and ensuring the stability of the sliding of the first sliding housing 112.

[0075] In this embodiment of the disclosure, the sliding of the first sliding housing 112 relative to the first main housing 111 can be manual or electric.

[0076] When the sliding of the first sliding housing 112 relative to the first main housing 111 is done manually, optionally, a first elastic limiting mechanism and a second elastic limiting mechanism are formed between the first sliding housing 112 and the first main housing 111, so that when the first sliding housing 112 slides relative to the first main housing 111, it can be limited to a first position or a second position, thereby ensuring that the first sliding housing 112 is in a retracted state or a rolled-up state relative to the first main housing 111.

[0077] When the sliding of the first sliding housing 112 relative to the first main housing 111 is electrically operated, such as Figure 6 As shown, the first main housing 11 also includes a first transmission mechanism 113, which includes a drive motor 1131 and a transmission rack 1132. The drive motor 1131 is fixed to one of the first main housing 111 and the first sliding housing 112, and the transmission rack 1132 is fixed to the other of the first main housing 111 and the first sliding housing 112. The length direction of the transmission rack 1132 is perpendicular to the length direction of the first main housing 111, and the output shaft of the drive motor 1131 is connected to the transmission rack 1132.

[0078] In the case where the first transmission mechanism 113 includes a transmission rack 1132, the stability of the first main housing 11 when it is in a sliding state can be ensured by the cooperation between the drive motor 1131 and the transmission rack 1132, thereby ensuring the flatness of the flexible display screen 3 and ensuring the display effect of the display device.

[0079] The number of transmission racks 1132 can be one or more. When the first transmission mechanism 113 includes multiple transmission racks 1132, the arrangement direction of the multiple transmission racks 1132 is parallel to the length direction of the display device. This allows the first sliding housing 112 to slide relative to the first main housing 111 at multiple positions, thereby ensuring the stability of the first main housing 11 when switching between the sliding state and the retracted state.

[0080] For example, such as Figure 6 As shown, the first transmission mechanism 113 includes two transmission racks 1132, namely a first transmission rack and a second transmission rack. In order to achieve synchronous transmission of the first transmission rack and the second transmission rack by the drive motor 1131, the drive motor 1131 is a dual-axis output motor, in which case the two output shafts of the drive motor 1131 are respectively connected to the first transmission rack and the second transmission rack; or, the first transmission mechanism 113 includes two drive motors 1131, namely a first drive motor and a second drive motor, with the first drive motor connected to the first transmission rack and the second drive motor connected to the second transmission rack.

[0081] In the case where the drive motor 1131 is a dual-axis output motor, the synchronicity of the movement of the first transmission rack and the second transmission rack can be well guaranteed; however, in the case where the first transmission mechanism 113 includes the first drive motor and the second drive motor, in order to ensure the synchronicity of the movement of the first transmission rack and the second transmission rack, it is necessary to control the first transmission rack and the second transmission rack synchronously through the same controller.

[0082] Optionally, such as Figure 6As shown, the first transmission mechanism 113 includes a transmission rod 1133, a drive motor 1131 is connected to the transmission rod 1133, and the transmission rod 1133 is connected to the transmission rack 1132.

[0083] The output shaft of the drive motor 1131 is connected to the transmission rod 1133 by a spur gear meshing or by a bevel gear meshing; a spur gear is fixed on the transmission rod 1133 so that the transmission rod 1133 can be connected to the transmission rack 1132 through the spur gear.

[0084] When the output shaft of the drive motor 1131 and the transmission rod 1133 are meshed by a spur gear, the axial direction of the output shaft of the drive electrode is parallel to the length direction of the transmission rod 1133. In this case, the drive motor 1131 and the transmission rod 1133 can be arranged along the length direction, thereby reducing the space occupied by the first transmission mechanism 113 as a whole inside the first main housing 11. When the output shaft of the drive motor 1131 and the transmission rod 1133 are meshed by a bevel gear, the axial direction of the output shaft of the drive electrode is perpendicular to the length direction of the transmission rod 1133. In this case, the drive motor 1131 can be arranged in a direction perpendicular to the length direction of the display device, and the transmission rod 1133 can be arranged along the length direction of the display device.

[0085] In the case where the first transmission mechanism 113 includes a transmission rod 1133, the number of transmission racks 1132 can be multiple, as long as a corresponding number of spur gears can be provided on the transmission rod 1133. This embodiment of the present disclosure does not limit this. Thus, by setting the transmission rod 1133, in the case of multiple transmission racks 1132, the distance between two adjacent transmission racks 1132 can be adjusted, thereby achieving relative sliding between the first sliding housing 112 and the first main housing 111 in a larger area, so as to ensure the stability when driving the first sliding housing 112 to slide.

[0086] When the drive motor 1131 and the transmission rack 1132 are connected via the transmission rod 1133, if the drive motor 1131 is a dual-axis output motor, such as Figure 6 As shown, the first transmission mechanism 113 includes two transmission rods 1133, namely the first transmission rod and the second transmission rod. The two output shafts of the dual-axis output motor are respectively connected to the first transmission rod and the second transmission rod. The first transmission rod is connected to the first transmission rack, and the second transmission rod is connected to the second transmission rack.

[0087] Optionally, in the case where the first transmission mechanism 113 includes a transmission rack 1132, one of the first sliding housing 112 and the first main housing 111 has a groove, and the transmission rack 1132 is fixed on the other of the first sliding housing 112 and the first main housing 111 and is slidably limited within the groove.

[0088] Thus, by fixing the transmission rack 1132 to one of the first sliding housing 112 and the first main housing 111, and limiting the other of the first sliding housing 112 and the first main housing 111, the stability of the first sliding housing 112 and the first main housing 111 when sliding relative to each other is ensured.

[0089] For example, the transmission rack 1132 is fixed inside the housing of the first main housing 111, and the inner wall of the first sliding housing 112 has a groove, in which the transmission rack 1132 is slidably limited.

[0090] Taking the second main housing 12 having a sliding state and a retracted state as an example, such as Figure 2 or Figure 4 As shown, the second main housing 12 includes a second main housing 121 and a second sliding housing 122. One side of the second main housing 121 along the length direction is connected to the folding mechanism 2. The second sliding housing 122 is connected to the side of the second main housing 121 away from the folding mechanism 2, and the second sliding housing 122 can slide relative to the second main housing 121 in a direction perpendicular to the length direction.

[0091] The structures of the second sliding housing 122 and the second main housing 121, as well as the sliding of the second sliding housing 122 relative to the second main housing 121, can all refer to the structures of the first sliding housing 112 and the first main housing 111 described in the above embodiments, and the sliding of the first sliding housing 112 relative to the first main housing 111. This disclosure will not elaborate further on these aspects. For example, the shell wall of the second main housing 121 has a plurality of first comb tooth structures 1111 facing the second sliding housing 122, and the shell wall of the second sliding housing 122 has a plurality of second comb tooth structures 1125 facing the second main housing 121. The plurality of first comb tooth structures 1111 mesh with the plurality of second comb tooth structures 1125.

[0092] In addition, such as Figure 5 As shown, the flexible display screen 3 includes, in addition to the first display area 32, the second display area 33, and the folding area 34 mentioned above, a second sliding area 36; the first display area 32 is limited on the first main housing 111, the second display area 33 is limited on the second main housing 121, and the second sliding area 36 is slidably fixed on the second sliding housing 122.

[0093] Thus, when the second sliding housing 122 moves away from the second main housing 121, the second sliding area 36 slides relative to the second sliding housing 122, so that the second sliding area 36 is in a flat state and coplanar with the second display area 33, so as to display the image in the second sliding area 36, ​​the first display area 32, the second display area 33, and the folding area 34; when the second sliding housing 122 slides towards the second main housing 121, the second sliding area 36 slides relative to the second sliding housing 122, so that the second sliding area 36 is in a rolled-up state, so as to display the image in the first display area 32, the second display area 33, and the folding area 34. In addition, when the second main housing 12 switches between the sliding state and the retracted state, the display device can switch between two different screen ratios simultaneously, thereby improving the display effect of the display device.

[0094] When the second sliding housing 122 slides electrically relative to the second main housing 121, such as Figure 6 As shown, the second main housing 12 also includes a second transmission mechanism 123, which is connected to the second main housing 121 and the second sliding housing 122 respectively. The specific structure of the second transmission mechanism 123 can be referred to the first transmission mechanism 113 described in the above embodiments, and the embodiments of this application do not limit it.

[0095] Optionally, for a display device where the first main housing 11 includes a first sliding housing 112 and the second main housing 12 includes a second sliding housing 122, the maximum sliding stroke of the first sliding housing 112 is equal to twice the maximum sliding stroke of the second sliding housing 122. That is, the width of the first sliding area 35 of the flexible display screen 3 described above is equal to twice the width of the second sliding area 36. Of course, the maximum sliding stroke of the first sliding housing 112 can also be greater than twice the maximum sliding stroke of the second sliding housing 122; this disclosure does not limit this.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
