It should be understood that such uses of these terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described.

[0061] As used herein, “about,” “approximately,” “close to,” or “basically” includes the value stated and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

For example, the aspect ratio of the channel, the thickness and spacing of each film layer, and the width and spacing of each signal line can be adjusted according to actual needs. The number of pixels in the display substrate and the number of sub-pixels in each pixel are not limited to the quantities shown in the figures.

[0065] In this specification, "electrical connection" includes the situation where components are connected together by elements that have a certain electrical function. There are no particular limitations on what constitutes an "electrical function," as long as it allows for the transmission and reception of electrical signals between the connected components.

[0066] In this specification, triangles, rectangles, trapezoids, pentagons, or hexagons are not strictly defined; they can be approximate triangles, rectangles, trapezoids, pentagons, or hexagons. Small deformations due to tolerances are possible, as are chamfers, curved edges, and other variations.

[0067] Traditional display products are mainly flat screens, such as for home viewing and business office use. However, with the continuous development of display technology, users have higher and higher visual demands for display products. For example, for larger displays, such as those used in the gaming industry, they can be made into concave curved surfaces to provide a wider viewing angle and a better sense of immersion.

[0068] In related technologies, the curvature of curved displays is fixed, resulting in poor viewing experience when viewing the display outside the optimal viewing distance or angle.

[0069] In view of this, embodiments of this application provide a display device that can at least to some extent adjust the curvature of the display module, thereby meeting the viewing needs of users at different distances or angles and improving the user experience.

[0070] The display device of the present application embodiment will be described below with reference to the specific accompanying drawings.

[0071] Figure 1 A structural diagram of a display device according to an embodiment of this application is shown; Figure 2 A top view of a display device according to an embodiment of this application is shown; Figure 3 An exploded view of a display device according to an embodiment of this application is shown from a first angle; Figure 4 An exploded view of the display device according to an embodiment of this application is shown from a second angle.

[0072] Combination Figures 1-4 The first aspect of this application provides a display device, including: a display module 1, a first connector 22, a second connector 23, a third connector 3, and a driving component 4. The display module 1 includes a display panel 11 and a back plate 12 disposed on the backlight side of the display panel 11; a support plate 21 is disposed on the side of the back plate 12 away from the display panel 11, including a first end and a second end disposed opposite to each other; a first connector 22 is disposed on the first end of the support plate 21, and a second connector 23 is disposed on the second end of the support plate 21, the first connector 22 being connected to a first connection position A of the back plate 12, and the second connector 23 being connected to a second connection position B of the back plate 12; a third connector 3 passes through the support plate 21 and is connected to a third connection position C of the back plate 12, the third connection position C being located between the first connection position A and the second connection position B; a driving assembly 4 is disposed on the side of the support plate 21 away from the back plate 12, connected to the third connector 3, and configured to drive the third connector 3 to move to adjust the relative distance between the third connection position C of the back plate 12 and the support plate 21, thereby adjusting the curvature of the display module 1.

[0073] Based on the above disclosure, in this embodiment, the first connector 22 is connected to the back plate 12 at the first connection position A, the second connector 23 is connected to the back plate 12 at the second connection position B, and the third connector 3 is connected to the back plate 12 at the third connection position C. According to the principle of three points forming a circle, the line connecting the first connection position A, the second connection position B, and the third connection position C can form an arc. Therefore, during the movement of the third connector 3 driven by the driving component 4, the support plate 21, the first connector 22, and the third connector 3 can maintain their positions essentially unchanged. A portion of the display module 1 is concave to varying degrees under the pulling or pushing of the third connector 3, changing the distance between point C of the back plate and the support plate 21, thereby changing the curvature of the arc. This allows for adjustment of the curvature of the display module 1, enabling switching between flat and curved screens. Furthermore, the curved screen can provide different curvatures to meet the viewing needs of users at different distances or angles, thus improving the user experience.

[0074] It is understood that the display devices in the embodiments of this application include, but are not limited to, products or components with display functions such as mobile phones, televisions, monitors, tablet computers, and navigators.

[0075] In some embodiments, the display module 1 includes, but is not limited to, an LED (Light Emitting Diode) display module 1, an LCD (Liquid Crystal Display) display module 1, an OLED (Organic Light Emitting Diode) display module 1, a Mini-LED display module 1, or a Micro-LED display module 1. Taking an LCD display module 1 as an example, the LCD display module 1 includes: a display panel 11 and a backplate 12 disposed on the backlight side of the display panel 11. The display panel 11 includes an array substrate (not shown), a color filter substrate (not shown) disposed opposite to the array substrate, and a liquid crystal layer (not shown) disposed between the array substrate and the color filter substrate. The backplate 12 may be disposed on the side of the array substrate away from the color filter substrate. Exemplarily, the backplate 12 may be a substrate that can be bent to a certain extent, such as an aluminum plate; the display panel 11 may be a substrate that can be bent to a certain extent, such as glass.

[0076] In some embodiments, the support plate 21 has a first end and a second end disposed opposite to each other. It is understood that the line connecting the first end and the second end is substantially parallel to the width direction of the back plate 12. The width direction of the back plate 12 may refer to the width direction when the curvature of the display module 1 is zero and the back plate 12 is not bent.

[0077] In some embodiments, the support plate 21 is disposed on the side of the back plate 12 away from the display panel 11, and the first connector 22 and the second connector 23 are located between the support plate 21 and the back plate 12, thereby making the support plate 21 and the back plate 12 spaced apart, that is, there is a certain gap between the support plate 21 and the back plate 12.

[0078] It is worth noting that when the driving component 4 drives the third connector 3 to pull or push a portion of the display module 1, the gap between point C and the support plate 21 changes. For example, when the third connector 3 pulls a portion of the display module 1 (e.g., the area near point C in the width direction X), the distance between point C and the support plate 21 decreases, thereby increasing the curvature (or decreasing the radius of curvature) of the arc formed by the lines connecting points A, B, and C, which means that the curvature of the display module 1 increases (or decreases the radius of curvature). When the third connector 3 pushes a portion of the display module 1 (e.g., the area near point C in the width direction X), the distance between point C and the support plate 21 increases, thereby decreasing the curvature (or increasing the radius of curvature) of the arc formed by the lines connecting points A, B, and C, which means that the curvature of the display module 1 decreases (or increases the radius of curvature).

[0079] It is understandable that the extreme position of the third connector 3 pulling a part of the display module 1 can be the position where the back plate 12 contacts the support plate 21. At this time, the curvature of the display module 1 is the largest (or the radius of curvature is the smallest). The extreme position of the third connector 3 pushing a part of the display module 1 can be the position where the curvature of the display module 1 is 0. At this time, the display module 1 can be a flat screen.

[0080] It is also understandable that when the driving component 4 drives the third connector 3 to pull or push a part of the display module 1, due to the obstruction of the first connector 22 and the second connector 23, the gap between another part of the display module 1 (the area near points A and B in the width direction X) and the support plate 21 remains basically unchanged. Thus, it is equivalent to the display module 1 remaining stationary on both sides in the width direction X, and the middle area of ​​the display module 1 being concave inward, thereby making the display module 1 arc-shaped and thus achieving curvature adjustment.

[0081] In some embodiments, the support plate 21 is an arc-shaped support plate 21. Thus, the support plate 21 can be similar in shape to the display module 1 when it is bent, thereby achieving a conformal setting with the display module 1 and improving the stability of the structure.

[0082] Figure 5 A schematic diagram of the planar layout of the display panel is shown.

[0083] For example, such as Figure 1 As shown, the LCD product can be divided into a display area 101 (AA area, Active Area) and a bezel area 102 according to the area division. The bezel area 102 is divided into an upper bezel 121, a lower bezel 122, a left bezel 123, and a right bezel 124. The lower bezel 122 is provided with a DP (Data Pad, data trace side), including a glass electrode edge for bonding external electronic devices (such as driver ICs and flexible circuit boards). The upper bezel 121 is provided with a DPO (Data Pad Opposite, data trace opposite side), including a Gate metal trace area. The left bezel 123 and / or the right bezel 124 are provided with a GOA (Gate on Array, gate driver integration area 143), which is provided with a Gate (gate metal layer), an SD (source drain metal layer), an Active (active layer), and a passivation layer.

[0084] In some embodiments, the display panel 11 includes a display area and a border area disposed on at least one side of the display area; the back panel 12 includes a first side 121 and a second side 122 disposed opposite to each other in the width direction X of the back panel 12, the first connection position A is located on the first side 121, and the second connection position B is located on the second side 122. The orthographic projections of the first connection position A and the second connection position B on the display panel 11 are located in the display area, and there is a preset distance between the first connection position A and the second connection position B and the boundary line, the boundary line being the boundary line between the display area and the border area, and the ratio between the preset distance and the width of the display area is in the range of 0.10-0.20, for example 0.10, 0.15, 0.18, 0.20, etc.

[0085] In some embodiments, the ratio between the preset spacing and the width of the display area is 0.15.

[0086] It should be noted that the width direction X can refer to the direction from the left border to the right border mentioned above, and the left border and / or the right border are provided with a GOA (Gate on Array). Among them, the first side 121 of the backplate 12 is close to the left border, and the second side 122 of the backplate 12 is close to the right border.

[0087] Figure 6 The diagram shows the positions of the first connection position and the second connection position on the curve according to an embodiment of this application.

[0088] It is understandable that when the display panel 11 uses a glass substrate, the glass substrate has a certain degree of rigidity due to the characteristics of the glass material. Therefore, although the glass substrate can be bent, it has high hardness and strong tensile strength. When the glass substrate is bent, the stress is mainly concentrated in the middle area of ​​the glass substrate, while the edge area remains flat. Furthermore, with the support of the support plate 21, the first connector 22, and the second connector 23, the edge area is even less prone to deformation. Therefore, in this embodiment, the first connection position A and the second connection position B can be designed according to the changing characteristics of the glass substrate. For example... Figure 6As shown, the curve of the display panel 11 is divided into a central arc segment and two straight segments on either side. As point C moves closer to or further away from the support plate 21, the area of ​​the display module 1 corresponding to the straight segments on either side remains flat, while the curvature of the area of ​​the display module 1 corresponding to the central arc segment changes. Therefore, in this embodiment, the first connection position A and the second connection position B can be designed by determining the boundary line between the straight and arc segments. For example, the first connection position A and the second connection position B can be set on the boundary line. In this case, the display module 1 experiences uniform force and no waste during the pulling or pushing process; alternatively, the first connection position A and the second connection position B can be set near the boundary line, thus still achieving the effect of uniform force and minimal waste.

[0089] In some embodiments, the first connection position A and the second connection position B are symmetrically arranged with respect to the third connection position C.

[0090] For example, in the width direction X of the back plate 12, the first connection position A and the second connection position B are symmetrically arranged with respect to the third connection position C, so that when the distance between the third connection position C and the support plate 21 is adjusted, the support plate 21, the first connector 22 and the second connector 23 can provide uniform support force to the display module 1, ensuring the structural stability of the display module 1 during movement.

[0091] In some embodiments, the third connection position C is located at the center of the back plate 12.

[0092] Understandably, when the third connector 3 applies a pulling or pushing force from the center of the backplate 12 to the display module 1, the pulling or pushing force will be transmitted symmetrically along the display module 1, so that the degree of curvature on both sides is basically the same, avoiding twisting or wrinkling caused by local stress concentration (especially the glass substrate and thin film layer); in addition, the center drive can ensure a smooth transition of the overall curvature of the display module 1, reduce the deformation lag in the edge area, and is suitable for scenarios that require optical uniformity (such as curved screen display); in addition, the edges of the display module 1 usually have encapsulation glue, circuit traces or interfaces, etc., and applying force at the center can reduce the mechanical stress on these sensitive areas and reduce the risk of breakage.

[0093] Figure 7 A schematic diagram of the structure of the first connector 22 according to an embodiment of this application is shown; Figure 8 An exploded view of the first connector 22 according to an embodiment of this application is shown. It is worth noting that the first connector 22 and the second connector 23 have the same structure. Figure 7 and Figure 8 Only a schematic diagram of the first connector 22 is shown, but the structure of the second connector 23 can also be referenced. Figure 7 and Figure 8 This will not be elaborated upon here.

[0094] In some embodiments, the first connector 22 and the second connector 23 have the same structure. The first connector 22 includes: a first connecting block 22A, a second connecting block 22B, and a rotating shaft member 22C. The first connecting block 22A is connected to the back plate 12 and has a first through hole 22A1. The second connecting block 22B is connected to the support plate 21 and overlaps with the first connecting block 22A. The second connecting block 22B has a second through hole 22B1, which overlaps with the first through hole 22A1. The shape of the second through hole 22B1 is a runway hole in the width direction X of the back plate 12, and the width of the second through hole 22B1 is greater than the width of the first through hole 22A1. The rotating shaft member 22C passes through the first through hole 22A1 and the second through hole 22B1, and the first through hole 22A1 forms a radial constraint on the rotating shaft member 22C.

[0095] It should be noted that the radial constraint formed by the first through hole 22A1 on the rotating shaft component 22C means that when the rotating shaft is inserted into the first through hole 22A1, the first through hole 22A1 restricts the degree of freedom of the rotating shaft in the radial direction (perpendicular to the axis of the rotating shaft), making it unable to move freely within the first through hole 22A1.

[0096] It is understood that the first connecting block 22A and the second connecting block 22B are connected by a pivot member 22C. In the width direction X of the back plate 12, the width of the second through hole 22B1 is greater than the width of the first through hole 22A1 (the shape of the second through hole 22B1 is a "racetrack hole"). That is, the second through hole 22B1 has a larger gap in the width direction X compared to the first through hole 22A1. Therefore, when the third connecting member 3 pulls or pushes a part of the display module 1, the pivot can drive the first connecting block 22A to rotate slightly relative to the second connecting block 22B, preventing jamming between the first connecting block and the second connecting block 22B and preventing rotation.

[0097] In some embodiments, the rotating shaft component 22C includes: a washer 22C1, a nut 22C3 and a bolt 22C4. The washer 22C1 is provided with a third through hole 22C2. The bolt 22C4 passes through the first through hole 22A1, the second through hole 22B1 and the third through hole 22C2 and is threadedly connected to the nut 22C3.

[0098] In some embodiments, the third connector 3 includes a third connecting block 31 and a lead screw 32. The third connecting block 31 is connected to the third connecting position C of the back plate 12; the lead screw 32 passes through the support plate 21 and is connected to the third connecting block 31.

[0099] For example, the third connecting block 31 can be fixed to the back plate 12, for example by screws. The center of the orthographic projection of the third connecting block 31 on the back plate 12 can overlap with the third connecting position C. One end of the lead screw 32 near the back plate 12 is connected to the third connecting block 31, so that when the lead screw 32 moves, it can drive the third connecting block 31 and the display module 1 to move.

[0100] In some embodiments, the drive assembly 4 includes a gearbox 41 and a drive motor 42. The gearbox 41 is disposed on the side of the support plate 21 away from the back plate 12, and includes a first gear 41A and a second gear 41B that mesh with each other. The first gear 41A includes a first threaded hole 41A1, which is threadedly connected to the lead screw 32. The second gear 41B includes a second threaded hole 41B1. The drive motor 42 is disposed on the side of the support plate 21 away from the back plate 12, and includes an output shaft 42A, which is threadedly connected to the second threaded hole 41B1.

[0101] It is understandable that the rotation of the first gear 41A and the second gear 41B is opposite. When the drive motor 42 drives the second gear 41B to rotate forward through the output shaft 42A, the first gear 41A rotates in reverse. At this time, the lead screw 32, which is threadedly connected to the first gear 41A, moves under the action of the thread, which drives the third connecting block 31 to move, and then drives the display module 1 to move, thereby realizing the displacement of point C.

[0102] In some embodiments, the radius of curvature of the display module 1 is in the range of 1000mm-2500mm, for example, 1000mm, 1200mm, 1400mm, 1600mm, 1800mm, 2000mm, 2100mm, 2200mm, 2400mm or 2500mm.

[0103] Therefore, the display module 1 of this application embodiment can achieve curvature adjustment within a curvature radius range of 1000mm-2500mm, which can meet the viewing needs of users at different viewing distances and angles.

[0104] In some embodiments, the initial radius of curvature of the display module 1 is 1400 mm.

[0105] It should be noted that the initial radius of curvature refers to the radius of curvature of the display module 1 when it leaves the factory. This radius of curvature can ensure that the stroke change of the display module 1 is minimized during subsequent adjustments, that is, the stroke to the limit position of the radius of curvature is minimized, thereby reducing the power consumption of the motor to a certain extent.

[0106] In some embodiments, the system further includes a control circuit 5 and an instruction receiving module. The control circuit 5 is electrically connected to the drive component 4; the instruction receiving module is electrically connected to the control circuit 5 and configured to receive curvature adjustment instructions from a user. The instruction receiving module includes curvature adjustment buttons 6 and / or a pickup module 7.

[0107] Understandably, a DP (Data Pad) is provided on the lower bezel (bonding side) of display module 1, including a glass electrode edge for bonding external electronic devices (such as driver ICs and flexible circuit boards). Control circuit 5 can be an MCU (Microcontroller Unit) within the driver IC, and control circuit 5 is electrically connected to the instruction receiving module.

[0108] In some embodiments, the curvature adjustment button 6 can be a mechanical button located on the display module 1, allowing the user to issue curvature adjustment commands by touching the mechanical button; the sound pickup module 7 can be a sound pickup sensor, such as a microphone, allowing the user to issue curvature adjustment commands by uttering voice commands (e.g., "increase curvature" or "decrease curvature"). The curvature adjustment command is transmitted to the control circuit 5 in the form of an electrical signal. After receiving the electrical signal, the control circuit 5 sends a control electrical signal to the drive motor 42 of the drive assembly 4, thereby causing the drive motor 42 to drive the third connecting member 3 to move.

[0109] The curvature adjustment command can include a curvature increase command and a curvature decrease command. The curvature increase command can be transmitted to the control circuit 5 in the form of a first electrical signal, and the curvature decrease command can be transmitted to the control circuit 5 in the form of a second electrical signal. For example, the first electrical signal can be a high-level signal and the second electrical signal can be a low-level signal, or the first electrical signal can be a low-level signal and the second electrical signal can be a high-level signal. No limitation is made here.

[0110] For example, the control circuit 5 can be a logic gate circuit, and the electrical signal corresponding to the curvature adjustment command can be used as the trigger signal of the logic gate circuit to trigger the logic gate circuit to issue a control signal, which can be a pulse signal.

[0111] In some embodiments, the system further includes: a control circuit 5 and a distance sensor 8, wherein the control circuit 5 is electrically connected to the drive assembly 4; and the distance sensor 8 is electrically connected to the control circuit 5 and configured to detect the distance between the user and the display module 1.

[0112] When a user is within 0.5 to 1 meter of the light-emitting side of the display module 1, they can be detected by the distance sensor 8; when the user is within this distance range, the initial radius of curvature of the display module 1 can be set to 1400 mm.

[0113] It is understandable that after the distance sensor 8 detects the distance between the user and the display module 1, the display module 1 can send a control signal to the drive motor 42 of the drive assembly 4 based on the distance, so that the drive motor 42 drives the third connecting member 3 to move. The principle by which the display module 1 sends a control signal to the drive motor 42 based on the distance can be found in related technologies, such as the patent with patent number "ZL202310590902.4" entitled "A Display Device and Curvature Adjustment Method", which describes "the control board controlling the movement of the drive member based on the viewing distance fed back by the distance detector, thereby adjusting the curvature of the flexible screen".

[0114] Figure 9 Another schematic diagram of the display device according to an embodiment of this application is shown; Figure 10 Another structural schematic diagram of a display device according to an embodiment of this application is shown.

[0115] In some embodiments, the system further includes: a housing 9, a curvature adjustment button 6, a support base 10, a microphone module 7, a distance sensor 8, and a control circuit 5. The housing 9 houses the display module 1, the support assembly 2, the third connector 3, and the drive assembly 4, and exposes the light-emitting side of the display module 1. The curvature adjustment button 6 for adjusting curvature is disposed on the housing 9. The support base 10 is connected to the housing 9. The microphone module 7 and the distance sensor 8 are disposed on the support base 10. The control circuit 5 is electrically connected to the drive assembly 4, the curvature adjustment button 6, the microphone module 7, and the distance sensor 8.

[0116] Figure 11 A circuit structure block diagram of a display device according to an embodiment of this application is shown.

[0117] For example, the drive motor 42 can be equipped with a corresponding first control sub-circuit 51 for receiving control signals from the control circuit 5, the pickup module 7 can be equipped with a corresponding second control sub-circuit 52 for sending curvature adjustment commands to the control circuit 5, the distance sensor 8 can be equipped with a corresponding third control sub-circuit 53 for sending distance detection signals to the control circuit 5, and the curvature adjustment button 6 can be equipped with a corresponding fourth control sub-circuit 205 for sending curvature adjustment commands to the control circuit 5. The first control sub-circuit 51 to the fourth control sub-circuit 205 are electrically connected to the control circuit 5, thereby achieving overall control linkage. This allows for adjustment to a relatively suitable initial curvature shape through distance sensing, and then allows the user to make the best curvature adjustment through voice or the curvature adjustment button 6.

[0118] Understandably, housing the display module 1, the support component 2, the third connector 3, and the drive component 4 within the casing ensures the aesthetics of the display device and prevents these components from being affected by the external environment. Furthermore, the inclusion of a curvature adjustment button 6, a microphone module 7, and a distance sensor 8 within the display device allows for multiple methods to adjust the curvature of the display module 1, enhancing the user experience.

[0119] Based on the above disclosure, the display module 1 of this application embodiment includes a display panel 11 and a back plate 12. A support, disposed on the side of the back plate 12 away from the display panel 11, includes a first end and a second end disposed opposite to each other. A first connector 22 is disposed at the first end of the support plate 21, and a second connector 23 is disposed at the second end of the support plate 21. The first connector 22 is connected to a first connection position A of the back plate 12, and the second connector 23 is connected to a second connection position B of the back plate 12. A drive assembly 4, disposed on the side of the support plate 21 away from the back plate 12, is connected to the third connector 3 and configured to drive the third connector 3 to move to adjust the relative distance between the third connection position C of the back plate 12 and the support plate 21, thereby adjusting the curvature of the display module 1.

[0120] Therefore, in this embodiment, the first connector 22 is connected to the first connection position A of the back plate 12, the second connector 23 is connected to the second connection position B of the back plate 12, and the third connector 3 is connected to the third connection position C of the back plate 12. According to the principle of three points forming a circle, the line connecting the first connection position A to the third connection position C can form an arc. During the process of the driving component 4 driving the third connector 3 to move, the support plate 21, the first connector 22, and the third connector 3 can maintain their positions basically unchanged. Under the pulling or pushing of the third connector 3, a part of the display module 1 changes the distance between the third connection position C of the back plate 12 and the support plate 21, thereby changing the curvature of the arc. This allows the curvature of the display module 1 to be adjusted. On the one hand, it can realize the switching between flat screen and curved screen. On the other hand, the curved screen can provide different curvatures to meet the viewing needs of users at different distances or angles and improve the user experience.
