[0063] In the following description, for the purpose of explanation, many specific details are set forth to provide a comprehensive understanding of the various exemplary embodiments. However, it is apparent that the various exemplary embodiments can be implemented without these specific details or with one or more equivalent arrangements. In other cases, well-known structures and devices are shown in block diagram form to avoid unnecessarily obscuring the various exemplary embodiments. In addition, the various exemplary embodiments can be different, but not necessarily exclusive. For example, the specific shape, configuration, and characteristics of the exemplary embodiment can be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0064] In the accompanying drawings, the sizes and relative sizes of the elements may be exaggerated for clarity and / or descriptive purposes. Thus, the sizes and relative sizes of the individual elements are not necessarily limited to those shown in the drawings. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed differently from the described sequence. For example, two processes described in succession can be performed substantially simultaneously or in an order opposite to the described sequence. In addition, the same reference numerals represent the same elements.

[0065] When an element is described as being "on" another element, "connected to" another element, or "coupled to" another element, the element may be directly on, directly connected to, or directly coupled to another element, or there may be an intermediate element. However, when an element is described as being "directly on" another element, "directly connected to," or "directly coupled to," another element, there is no intermediate element. Other terms and / or expressions used to describe the relationship between elements should be interpreted in a similar manner, for example, "between" versus "directly between," "adjacent" versus "directly adjacent," or "on" versus "directly on," etc. In addition, the term "connected" may refer to a physical connection, an electrical connection, a communication connection, and / or a fluid connection. In addition, the X-axis, the Y-axis, and the Z-axis are not limited to the three axes of a rectangular coordinate system, and may be interpreted in a broader sense. For example, the X-axis, the Y-axis, and the Z-axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” may be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XY, YZ, and XZ. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0066] It should be understood that although the terms first, second, etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. For example, a first element may be named a second element, and similarly, a second element may be named a first element without departing from the scope of the exemplary embodiments.

Figure 2 Schematically shows a plan view of a display panel in a display module in an unfolded state according to some embodiments of the present disclosure.

[0068] Combined with reference Figure 1A 、 Figure 1B and Figure 2 The display module includes a display panel 100, a supporting housing 200, a first sliding mechanism 300, and a second sliding mechanism 400. The display panel 100 includes a first planar display portion 100A, a second planar display portion 100B, and a flexible display portion 100C. The flexible display portion 100C is connected between the first planar display portion 100A and the second planar display portion 100B. The light-emitting surfaces of the first planar display portion 100A and the second planar display portion 100B are flat, while the light-emitting surface of the flexible display portion 100C can be flat or bent into a curved surface.

[0069] For example, the display panel 100 is a single-side light-emitting type display panel, and the surface of the display panel 100 that emits light and displays an image is the light-emitting surface.

[0070] The supporting housing 200 includes a first supporting housing 210 and a second supporting housing 220, which are spaced apart. The first supporting housing 210 is disposed on the side of the first planar display portion 100A facing away from the light-emitting surface and is fixedly connected to the first planar display portion 100A. The support provided by the first supporting housing 210 allows the light-emitting surface of the first planar display portion 100A to remain flat. The second supporting housing 220 is disposed on the side of the second planar display portion 100B facing away from the light-emitting surface and is fixedly connected to the second planar display portion 100B. The support provided by the second supporting housing 220 allows the light-emitting surface of the second planar display portion 100B to remain flat. The flexible display portion 100C is disposed in the space between the first supporting housing 210 and the second supporting housing 220. No supporting housing is provided on the side of the flexible display portion 100C facing away from the light-emitting surface, allowing the flexible display portion 100C to bend.

[0071] The first sliding mechanism 300 is disposed on the first supporting housing 210. The first sliding mechanism 300 is configured to move the first supporting housing 210 along a first direction D1 toward a side closer to or farther from the second sliding mechanism 400. The first direction D1 is substantially parallel to the light-emitting surface of the first planar display portion 100A. The second sliding mechanism 400 is disposed on a side of the second supporting housing 220 away from the first supporting housing 210. The second sliding mechanism 400 is configured to move the side of the second supporting housing 220 away from the first supporting housing 210 along a second direction D2. The second direction D2 intersects the light-emitting surface of the second planar display portion 100B. The plane defined by the first direction D1 and the second direction D2 is substantially perpendicular to the light-emitting surface of the first planar display portion 100A.

[0072] In one display state, the positions of the first flat display portion 100A and the second flat display portion 100B are set by the first sliding mechanism 300 and the second sliding mechanism 400 so that the light emitting surface of the first flat display portion 100A and the light emitting surface of the second flat display portion 100B are located in the same plane (i.e., Figure 1A When it is necessary to switch to another display state, the side of the second planar display portion 100B away from the first planar display portion 100A moves along the second direction D2 under the control of the second sliding mechanism 400. At the same time, the first planar display portion 100A moves along the first direction D1 toward the second sliding mechanism 400 under the control of the first sliding mechanism 300. During this process, the bendable display portion 100C bends, and the light-emitting surface of the first planar display portion 100A and the light-emitting surface of the second planar display portion 100B form a preset angle β (i.e., as shown in FIG. 1 ). Figure 1B At this angle, the user can more conveniently perform operations such as typing and touching on the second flat display portion 100B.

[0073] In the display module provided in the embodiment of the present disclosure, a first sliding mechanism 300 and a second sliding mechanism 400 are provided. Through the mutual cooperation between the first sliding mechanism 300 and the second sliding mechanism 400, the display panel 100 can present different forms to meet more diversified application scenarios.

[0074] According to some exemplary embodiments, the sliding ranges of the first sliding mechanism 300 and the second sliding mechanism 400 are respectively set so that during the sliding process, a preset angle β formed between the light-emitting surface of the first planar display portion 100A and the light-emitting surface of the second planar display portion 100B is less than 180° and greater than or equal to 90°. When within this angle range, the convenience of typing and touching on the second planar display portion 100B is met while ensuring a better display effect.

[0075] For example, the preset angle β formed between the light emitting surface of the first planar display portion 100A and the light emitting surface of the second planar display portion 100B is 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160° or 170°.

Figure 4D Schematically shows a left view of a first sliding mechanism in a display module according to some embodiments of the present disclosure. Figure 4E Schematically shows a bottom view of a first sliding mechanism in a display module according to some embodiments of the present disclosure.

[0077] According to some exemplary embodiments, in conjunction with reference Figure 1A and Figure 3 The first sliding mechanism 300 can be provided on the side of the first supporting shell 210 away from the first flat display portion 100A, and then combined with reference to Figures 4A-4E The first sliding mechanism 300 includes a first sliding member 310, a second sliding member 320 and a first control system 330. The first sliding member 310 is fixedly arranged on a side of the first supporting shell 210 away from the first plane display portion 100A. The second sliding member 320 is used to be fixedly arranged on the component to be installed. The second sliding member 320 and the first sliding member 310 are slidably connected along the first direction D1. The first control system 330 is configured to control the relative sliding between the first sliding member 310 and the second sliding member 320. The second sliding member 320 is a fixed end and the first sliding member 310 is a movable end. The first sliding member 310 drives the first supporting shell 210 and the first plane display portion 100A to move along the first direction D1 relative to the component to be installed.

[0078] It should be noted that the components to be installed mentioned in the embodiments of the present disclosure should be understood as various devices that require the display module to realize the display function. For example, when the display module is installed in a vehicle as an in-vehicle display screen, the component to be installed can be the vehicle's center console.

[0079] According to some exemplary embodiments, in conjunction with reference Figure 1A 、 Figures 4A-4EThe first sliding member 310 may include a first rack guide 311 and a first rack housing 312.

The first racks 311a extend along a third direction D3 that is perpendicular to the first direction D1. The plurality of first racks 311a are arranged along the first direction D1 and are sequentially connected.

[0080] The second sliding member 320 includes a first gear 321, which is engaged with the first rack guide 311. The first control system 330 has a built-in drive motor, which is connected to the gear shaft of the first gear 321. The first control system 330 is configured to control its built-in drive motor to drive the first gear 321 to rotate counterclockwise or clockwise, thereby causing the first rack guide 311 to move along the first direction D1.

[0081] According to some exemplary embodiments, in conjunction with reference Figure 3 and Figure 4A The first rack housing 312 is fixed to the first support housing 210, thereby fixing the first sliding member 310 to the first support housing 210. When the first sliding member 310 moves, the first support housing 210 moves with it. For example, the first rack housing 312 can be fixed to the first support housing 210 by bolts.

[0082] According to some exemplary embodiments, in conjunction with reference Figure 4B and Figure 4E The first rack housing 312 has a stop bar 3121, and the housing of the first control system 330 has a ridge 331. The stop bar 3121 and the ridge 331 cooperate with each other so that the first gear 321 will not separate from the first rack guide rail 311 during the sliding process.

[0083] According to some exemplary embodiments, in conjunction with reference Figure 1A and Figure 4B The second sliding member 320 includes two first gears 321 , and the two first gears 321 are spaced apart along the first direction D1 .

[0084] According to some exemplary embodiments, in conjunction with reference Figures 4A-4E The first sliding mechanism 300 further includes a connecting member 340 , one end of which is fixedly connected to a side of the first control system 330 away from the first sliding member 310 , and the other end of the connecting member is used for mounting on a component to be mounted.

The third sliding member 410 is arranged on a side of the second supporting shell 220 away from the first supporting shell 210. The fourth sliding member 420 is arranged on the component to be installed. The fourth sliding member 420 and the third sliding member 410 are slidably connected along the second direction D2. The fourth sliding member 420 is a fixed end and the third sliding member 410 is a movable end. The third sliding member 410 drives the second supporting shell 220 and the second planar display portion 100B to move along the second direction D2 relative to the component to be installed.

[0087] According to some exemplary embodiments, in conjunction with reference Figure 4A 、 Figure 5A and Figure 5B The second sliding mechanism 400 is electrically connected to the first control system 330, which is configured to control the relative sliding between the third sliding member 410 and the fourth sliding member 420. Considering that the sliding processes of the first sliding mechanism 300 and the second sliding mechanism 400 occur simultaneously, electrically connecting the second sliding mechanism 400 to the first control system 330 can simplify the structure and control method of the display module.

[0088] According to some exemplary embodiments, in conjunction with reference Figure 1A 、 Figure 5A 、 Figure 5B 、 Figure 6A and Figure 6B The fourth sliding member 420 includes a second rack guide 421 and a second rack housing 422.

Since the position of the second rack guide 421 is fixed, the second gear 411 moves along the second direction D2 (according to FIG. 2 ). Figure 8C The second gear 411 moves to the left (as viewed from the perspective shown), and drives the second supporting housing 220 to move toward a side away from the first supporting housing 210 along the second direction D2.

[0102] It should be understood that when Figure 1B The display status is switched to Figure 1A In the illustrated display state, the above-mentioned motion trajectory is opposite, which will not be described here.

[0103] According to some exemplary embodiments, referring to Figure 2 The display panel 100 also includes a rollable display portion 100D and a tail end connecting portion 100E.

[0104] Combined with reference Figure 1C and Figure 3 The display module also includes a curling mechanism 500, and the tail end connection portion 100E is fixedly connected to the curling mechanism 500. The curling mechanism 500 is configured so that the light-emitting surface of at least a portion of the rollable display portion 100D is located in the same plane as the light-emitting surface of the first planar display portion 100A and / or so that the light-emitting surface of at least a portion of the rollable display portion 100D is located on the side of the first planar display portion 100A away from the light-emitting surface, that is, the curling mechanism 500 can change the area of ​​the portion of the rollable display portion 100D that is coplanar with the first planar display portion 100A, thereby adjusting the area of ​​the display panel 100 actually used for display according to display requirements.

Figure 9B Schematically shows Figure 9A An enlarged view of the component marked C in FIG. Figure 9C Schematically shows Figure 9A Enlarged view of the middle support plate. Figure 9D Schematically shows Figure 9A An enlarged view of the first support shell. Figure 10A An exploded view of a display module according to some embodiments of the present disclosure is schematically shown. Figure 10B Schematically shows Figure 10A An enlarged view of the first support shell. Figure 10C Schematically shows Figure 10A An enlarged view of the support plate. Figure 9A The exploded view from the light-emitting side of the display panel is shown. Figure 10A The exploded view of the display panel viewed from the side away from the light emitting surface is shown.

[0106] According to some exemplary embodiments, in conjunction with reference Figure 1C 、 Figure 9A and Figure 9B The rolling mechanism 500 includes a support plate 510 and a rotating member 520. The support plate 510 is located on a side of the first support housing 210 away from the first planar display portion 100A. The support plate 510 is slidably connected to the first support housing 210 along a first direction D1. The rotating member 520 includes a rotating shaft 521 and a rotating post 522 disposed on the outer periphery of the rotating shaft 521. The rotating shaft 521 is connected to the side of the support plate 510 away from the first support housing 210 along the first direction D1. The rotating post 522 is configured to rotate freely about the axial direction of the rotating shaft 521. The axial direction of the rotating shaft 521 is parallel to the side where the rollable display portion 100D is connected to the first planar display portion 100A. One side of the rollable display portion 100D is connected to the first planar display portion 100A, and the other side is wound along the surface of the rotating post 522 to the side of the first planar display portion 100A away from the light-emitting surface and fixedly connected to the support plate 510 via the tail connection portion 100E.

[0107] The support plate 510 can move along the first direction D1 relative to the first supporting shell 210, thereby changing the area of ​​the portion of the rollable display portion 100D that is coplanar with the first planar display portion 100A. At the same time, when the rollable display portion 100D is unfolded or rolled up, the rotating member 520 rotates to reduce the friction between the rollable display portion 100D and the rolling mechanism 500, thereby preventing damage to the rollable display portion 100D.

[0108] For example, the support plate 510 moves along the first direction D1 toward the side away from the first support shell 210, that is, Figure 1A The display status shown is switched by Figure 1CIn the display state shown, the portion of the rollable display portion 100D located on the side of the rotating member 520 away from the first planar display portion 100A can be slid to be coplanar with the first planar display portion 100A, thereby increasing the actual display area of ​​the display panel 100.

[0109] For example, the support plate 510 moves along the first direction D1 toward the side close to the first support shell 210, that is, Figure 1C The display status shown is switched by Figure 1A In the display state shown, the portion of the rollable display portion 100D coplanar with the first planar display portion 100A can be slid to the side of the rotating member 520 away from the first planar display portion 100A, thereby reducing the actual display area of ​​the display panel 100.

[0110] According to some exemplary embodiments, in conjunction with reference Figure 1A-1D The first sliding mechanism 300 and the second sliding mechanism 400 cooperate with each other so that the light emitting surface of the first planar display portion 100A and the light emitting surface of the second planar display portion 100B are coplanar (ie Figure 1A or Figure 1C As shown), or the light emitting surface of the first planar display portion 100A and the light emitting surface of the second planar display portion 100B form a certain angle (ie, as shown Figure 1B or Figure 1D As shown). The first sliding mechanism 300, the second sliding mechanism 400 and the rolling mechanism 500 are independent of each other. The bending of the bendable display portion 100C and the rolling of the rollable display portion 100D can be performed separately or simultaneously. By sliding and rolling the rolling mechanism 500, more of the rollable display portion 100D can be made coplanar with the first flat display portion 100A (i.e., Figure 1C or Figure 1D ), or more of the rollable display portion 100D is located on the side away from the first planar display portion 100A (ie, as shown in FIG. Figure 1A or Figure 1B shown).

[0111] According to some exemplary embodiments, in conjunction with reference Figure 1C and Figures 9A-9D A third gear 530 is disposed on the side of the first support housing 210 near the support plate 510. A third rack guide 540 extending in the first direction D1 is disposed on the side of the support plate 510 near the first support housing 210. The third rack guide 540 includes a plurality of third racks 540a extending in the third direction D3. The plurality of third racks 540a are arranged and sequentially connected along the first direction D1. The third gear 530 meshes with the third rack guide 540, allowing the support plate 510 to slide in the first direction D1 relative to the first support housing 510.

[0112] According to some exemplary embodiments, in conjunction with reference Figure 9A and Figure 10A The curling mechanism further includes a second control system 550, which is configured to drive the third gear 530 to rotate. The second control system 550 can be fixed to the first supporting shell 210. The second control system 550 has a built-in drive motor, which is connected to the gear shaft of the third gear 530. The second control system 550 drives the third gear 530 to rotate by controlling the built-in drive motor.

[0113] According to some exemplary embodiments, in conjunction with reference Figure 1C 、 Figure 9A and Figure 9D The first supporting shell 210 includes a first part 210A and a second part 210B. Along the direction perpendicular to the light-emitting surface of the first planar display portion 100A, the thickness of the second part 210B is greater than the thickness of the first part 210A. The thickness of the second part 210B matches the radial dimension of the rotating column 522, thereby ensuring that the part of the rollable display portion 100D that is coplanar with the first planar display portion 100A and the part of the rollable display portion 100D located on the side of the rotating body 520 away from the first planar display portion 100A are basically parallel.

[0114] According to some exemplary embodiments, in conjunction with reference Figure 1C 、 Figures 9A-9D and Figures 10A-10B The second part 210B includes a hollow portion 211 on a side away from the first planar display portion 100A, and the second control system 550 is arranged in the second part 210B of the first supporting shell 210. The third gear 530 installed on the second control system 550 is exposed by the hollow portion 211, so that the third gear 530 is engaged with the third rack guide 540 located outside the first supporting shell 210.

[0115] According to some exemplary embodiments, in conjunction with reference Figure 1C 、 Figures 9A-9D and Figures 10A-10B The hollow portion 211 is in the shape of a strip extending along the first direction D1, and the width of the hollow portion 211 along the third direction D3 is greater than the width of the third rack guide rail 540 along the third direction D3. At least a portion of the third rack guide rail 540 is located in the hollow portion 211, thereby reducing the thickness of the display module. At the same time, there is no interference between the third rack guide rail 540 and the first support shell 210.

[0116] According to some exemplary embodiments, in conjunction with reference Figure 1C 、 Figures 9A-9CThe curling mechanism 500 also includes a spring telescopic rod 560 extending along the first direction D1. The rotating shaft 521 and the third rack guide rail 540 are connected through the spring telescopic rod 560. The third rack guide rail 540 is fixed on the surface of the support plate 510 close to the first support shell 210, thereby realizing the connection between the rotating shaft 521 and the support plate 510.

[0117] According to some exemplary embodiments, referring to Figure 9B The rotating member 520 includes at least two rotating posts 522 spaced apart along the axial direction of the rotating shaft 521. One end of a spring-type telescopic rod 560 is connected to the portion of the rotating shaft 521 exposed between two adjacent rotating posts 522. The other end of the spring-type telescopic rod 560 is connected to the support plate 510. As the support plate 510 slides, the spring-type telescopic rod 560 expands and contracts to ensure that the rollable display portion 100D remains stretched.

[0118] For example, two spring telescopic rods 560 are connected to the rotating shaft 521 , and the two spring telescopic rods 560 are respectively fixed to both sides of the third rack guide rail 540 along the third direction D3 , and the width direction of the third rack guide rail 540 is perpendicular to the extension direction of the third rack guide rail 540 .

[0119] According to some exemplary embodiments, in conjunction with reference Figure 1C 、 Figure 9A 、 Figure 9C 、 Figure 9D and Figure 10B The second part 210B of the first supporting shell 210 is provided with a limiting slide groove 212 on the side away from the first flat display portion 100A. The limiting slide groove 212 extends along the first direction D1. The support plate 510 is close to the sliding portion 511 on one side of the first supporting shell 210. The sliding portion 511 can slide along the first direction D1 in the limiting slide groove 212.

[0120] According to some exemplary embodiments, in conjunction with reference Figure 1C 、 Figure 10A and Figure 10C The support plate 510 is provided with a mounting groove 512 on one side away from the first support shell 210. The tail end connection portion 100E is provided in the mounting groove 512 and fixed to the support plate 510. For example, the tail end connection portion 100E is adhered to the mounting groove 512 by an adhesive layer.

[0121] Figure 11 The figure schematically shows the motion trajectory of the curling mechanism in the display module according to some embodiments of the present disclosure.

[0122] Reference Figure 11 , when Figure 1A The display status is switched to Figure 1CWhen the third gear 530 rotates (according to the Figure 11 As shown in the perspective, the third gear 530 rotates counterclockwise), since the position of the third gear 530 is fixed, the third rack guide 540 moves along the first direction D1 toward the side away from the first support shell 210, thereby driving the support plate 510 to move synchronously toward the side away from the first support shell 210.

[0123] It should be understood that when Figure 1C The display status is switched to Figure 1A In the illustrated display state, the above-mentioned motion trajectory is opposite, which will not be described here.

[0124] Figure 12 An exploded view of a display module according to some embodiments of the present disclosure is schematically shown.

[0125] According to some exemplary embodiments, referring to Figure 12 The display module also includes a pressure sensing module 160, which is disposed on the side of the second planar display portion 100B facing away from the light-emitting surface. Because the angle of the second planar display portion 100B can be adjusted, placing the pressure sensing module 160 on the back of the second planar display portion 100B helps improve pressure sensitivity.

[0126] For example, the pressure sensing module 160 is attached to a side of the second planar display portion 100B away from the light emitting surface through an adhesive layer.

[0127] Figure 13 A cross-sectional view of a display panel of a display module according to some embodiments of the present disclosure is schematically shown.

[0128] Reference Figure 13 , the light emitting surface of the display panel 100 ( Figure 13 Other structural layers are further provided on the side of the display panel 100 (shown as an upper surface) and the side away from the light emitting surface. A polarizing layer 110, an optical adhesive layer 120, and a cover layer 130 are provided on the light emitting surface side of the display panel 100. The optical adhesive layer 120 is located on the side of the polarizing layer 110 away from the display panel 100, and the cover layer 130 is located on the side of the optical adhesive layer 120 away from the display panel 100. A back film layer 140, a supporting backplane 150, a pressure sensing module 160, and a printed circuit board 170 are provided on the side of the display panel 100 away from the light emitting surface. The supporting backplane 150 is located on the side of the back film layer 140 away from the display panel 100, the pressure sensing module 160 is located on the side of the supporting backplane 150 away from the display panel 100, and the printed circuit board 170 is located on the side of the pressure sensing module 160 away from the display panel 100.

[0129] According to some exemplary embodiments, referring to Figure 13The display panel 100 also includes a bending binding portion 100F, which is connected to a side of the second planar display portion 100B away from the bending display portion 100C. The bending binding portion 100F is bent to a side of the printed circuit board 170 away from the second planar display portion 100B and is electrically connected to the printed circuit board 170.

[0130] According to some exemplary embodiments, referring to Figure 13 The supporting backplane 150 includes a first hollow pattern 151, the orthographic projection of which on the display panel 100 at least partially overlaps with the area where the bendable display portion 100C is located. The supporting backplane 150 includes a second hollow pattern 152, the orthographic projection of which on the display panel 100 at least partially overlaps with the area where the rollable display portion 100D is located. By providing hollow patterns in the areas of the supporting backplane corresponding to the bendable display portion 100C and the rollable display portion 100D, the bending or rolling capabilities of the areas corresponding to the bendable display portion 100C and the rollable display portion 100D can be improved while ensuring the supporting performance of the supporting backplane.

The distribution density of the plurality of first hollow portions 1511 is less than the distribution density of the plurality of second hollow portions 1521. Since the rollable display portion 100D is more flexible, the distribution density of the second hollow portions 1521 can be set to be greater to improve the rollability of the support backplate in the area corresponding to the rollable display portion 100D. Since the bendable display portion 100C is more flexible, the distribution density of the first hollow portions 1511 can be set to be slightly greater to improve the support capacity of the support backplate in the area corresponding to the bendable display portion 100C.
