[0039] The above display device and display terminal are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0040] The present application provides a display device 1, as shown in Figures 1 to 5, the display device 1 includes a display panel 10, a backlight module 20 and at least one excitation component 30. The backlight module 20 is arranged on the backlight surface of the display panel 10. The backlight module 20 includes an outer frame 21, and the outer frame 21 includes a connected side panel 211 and a bottom panel 212. The side panel 211 is arranged on the periphery of the bottom panel 212, and at least one avoidance groove 2111 is provided in the side panel 211. The excitation component 30 is arranged on the side of the backlight module 20 away from the display panel 10. The excitation component 30 includes a connected driving member 31 and an action member 32, the action member 32 is configured to pass through the avoidance groove 2111 and be connected to the display panel 10, and the driving member 31 is configured to drive the action member 32 to drive the display panel 10 to move.

[0041] In one or more embodiments, the display panel 10 is a liquid crystal panel, which can be any one of a vertical alignment (VA) type, a twisted nematic (TN) type, a super twisted nematic (STN) type, an in-plane switching (IPS) type, and a fringe field switching (FFS) type.

[0042] In one or more embodiments, the backlight module 20 is disposed on the backlight surface of the display panel 10 and is configured to provide a backlight source for the display panel 10. The side of the display panel 10 away from the backlight module 20 is a display surface, which is used for viewing. The backlight module 20 can be a direct-lit backlight or an edge-lit backlight, which is not limited in this application.

[0043] In one or more embodiments, the backlight module 20 includes an outer frame 21. The material of the outer frame 21 can be metal or plastic, but is not limited thereto. The outer frame 21 includes connected side panels 211 and a bottom panel 212. The bottom panel 212 and the side panels 211 are both flat panels. The largest surface of the bottom panel 212 is arranged approximately parallel to the display surface, and the largest surface of the side panels 211 can be arranged approximately perpendicular to the display surface. The bottom panel 212 and the side panels 211 form a receiving cavity, which can accommodate the light-emitting elements of the backlight module 20.

[0044] In one or more embodiments, an avoidance groove 2111 is provided in the side panel 211 . The avoidance groove 2111 can be provided in the side panel 211 , or the avoidance groove 2111 is provided on a side of the side panel 211 away from the center of the display device 1 .

[0045] In one or more embodiments, the excitation component 30 includes a driving member 31 and an actuating member 32. The driving member 31 includes a motor, which may be a linear motor or a rotor motor. The actuating member 32 may be a spring, such as a spring pin.

[0046] The actuating member 32 may pass through the avoidance groove 2111 and be connected to the display panel 10 . When the driving member 31 drives the actuating member 32 to move, the actuating member 32 may drive the display panel 10 to move, thereby achieving tactile feedback.

[0047] In one or more embodiments, the actuating member 32 may move linearly in a direction perpendicular to the display surface, or may swing in a direction perpendicular to the display surface, or may move linearly in a direction parallel to the display surface, without limitation in this application. The amplitude of the actuating member 32 may be set as desired. For example, the actuating member 32 may move in a direction perpendicular to the display surface with an amplitude of 0.05 mm, but is not limited thereto.

[0048] The present application integrates the excitation component 30 into the display device 1 and connects the action member 32 to the display panel 10, thereby shortening the vibration transmission path, reducing friction and damping in vibration transmission, reducing the vibration attenuation transmitted from the action member 32 to the display panel 10, and improving the vibration transmission efficiency.

[0049] In the display device 1 of the present application, as shown in Figures 2 to 4, the driving member 31 is disposed on the side of the bottom plate 212 away from the display panel 10. The avoidance groove 2111 is disposed in the side plate 211, or on the side of the side plate 211 away from the center of the display device 1.

[0050] In one or more embodiments, the driving member 31 is disposed on a side of the bottom plate 212 facing away from the display panel 10 .

[0051] Optionally, in some embodiments, as shown in FIG2 , which is a schematic cross-sectional view of the first display device 1 according to an embodiment of the present application, the bottom plate 212 is provided with a groove 2121 . The groove 2121 is provided on a surface of the bottom plate 212 facing away from the display panel 10 , and the driving member 31 is provided in the groove 2121 .

[0052] For example, the bottom plate 212 can be made of plastic, and the groove 2121 can be provided on the side of the bottom plate 212 away from the display panel 10. By providing the groove 2121 on the bottom plate 212, an accommodating space can be provided for the driving member 31. At the same time, the bottom plate 212 can replace the housing of the driving member 31.

[0053] In the first display panel 10 device, the driving direction of the driving member 31 can be along a direction roughly parallel to the maximum plane of the base plate 212, that is, the horizontal direction in Figure 2. The driving member 31 can drive the action member 32 to move in a direction roughly perpendicular to the maximum plane of the base plate 212, that is, the vertical direction in Figure 2. The action member 32 then drives the display panel 10 to move in the vertical direction, that is, in the direction perpendicular to the display surface.

[0054] Optionally, in some embodiments, as shown in FIG3 , FIG3 is a schematic cross-sectional view of a second display device 1 according to an embodiment of the present application. The second display device 1 differs from the first display device 1 in that no groove 2121 is provided on the bottom plate 212. The driving member 31 is disposed close to the surface of the bottom plate 212 facing away from the display panel 10. This arrangement can reduce the thickness of the bottom plate 212 and reduce the material cost of the bottom plate 212. In the second display device 1, the bottom plate 212 can be a sheet metal part, and the material of the bottom plate 212 can be iron, aluminum, or the like.

[0055] Optionally, in some embodiments, as shown in FIG4 , which is a schematic cross-sectional view of a third display device 1 according to an embodiment of the present application, the third display device 1 differs from the second display device 1 in the placement of the actuating member 30 . In the third display device 1 , the driver 31 is positioned near the edge of the base plate 212 , with the orthographic projection of the driver 31 on the base plate 212 located within the base plate 212 , and the orthographic projection of the actuating member 32 on the driver 31 located within the driver 31 .

[0056] The driving member 31 is arranged close to the edge of the base plate 212 and does not exceed the edge of the base plate 212. The positive projection of the action member 32 on the driving member 31 is located inside the driving member 31, so that the driving member 31 and the action member 32 are close to each other, further reducing the vibration transmission path between the driving member 31 and the action member 32 and improving the vibration transmission efficiency.

[0057] In one embodiment, the driving direction of the driving member 31 can be the same as the moving direction of the actuating member 32, thereby reducing kinetic energy loss. For example, the driving direction of the driving member 31 can be perpendicular to the display surface, and the moving direction of the actuating member 32 can also be perpendicular to the display surface, thereby avoiding kinetic energy loss caused by inconsistent movement directions of the driving member 31 and the actuating member 32.

[0058] In the display device 1 of the present application, as shown in Figures 2 to 4, the display panel 10 includes a stacked cover plate 11 and a display body 12, the cover plate 11 is arranged on the side of the display body 12 away from the backlight module 20, the orthographic projection of the display body 12 on the cover plate 11 is located inside the cover plate 11, and the orthographic projection area of ​​the display body 12 is smaller than the area of ​​the cover plate 11; wherein, the action member 32 is connected to the surface of one side of the cover plate 11 close to the backlight module 20.

[0059] In this embodiment, the cover plate 11 may be made of, but not limited to, polyimide, glass, etc. The cover plate 11 may protect the display body 12 and improve the impact resistance of the display device 1 .

[0060] In this embodiment, the display body 12 can be used for display. The display body 12 includes a display area and a non-display area arranged outside the display area. The display area is provided with a plurality of sub-pixels.

[0061] The display body 12 may include a first substrate and a second substrate in opposing relation, with a liquid crystal layer disposed therebetween. The first substrate may be a color filter substrate, which may include a plurality of color resists, such as red, blue, and green. The color resists may convert white light into corresponding colored light. For example, the red color resist allows red light to pass through while blocking light of other colors, the blue color resist allows blue light to pass through while blocking light of other colors, and the green color resist allows green light to pass through while blocking light of other colors. When white light passes through corresponding color resists of different colors, it may be converted into corresponding red, blue, and green light, thereby achieving color display.

[0062] The second substrate may be an array substrate, which may include an array layer, which includes a drive circuit configured to provide a drive voltage to each sub-pixel. The drive voltage controls the deflection of the liquid crystal molecules corresponding to each sub-pixel, thereby adjusting light transmittance and controlling the brightness of the image.

[0063] Optionally, in some embodiments, the color resist may also be disposed on the array substrate, that is, the display body 12 may be a COA (CF on Array, color resist is disposed on the array substrate) architecture, but is not limited thereto.

[0064] In this embodiment, optical adhesive may be provided between the cover plate 11 and the display body 12 , and the optical adhesive enables adhesion between the cover plate 11 and the display body 12 .

[0065] In this embodiment, the orthographic projection of the display body 12 on the cover plate 11 is located within the cover plate 11, and the orthographic projection area of ​​the display body 12 is smaller than the area of ​​the cover plate 11. In other words, the cover plate 11 covers the display body 12, and the edge of the cover plate 11 extends beyond the edge of the display body 12. The portion of the cover plate 11 that extends beyond the display body 12 can be connected to the actuating member 32, thereby achieving force transmission.

[0066] It should be understood that the connection between the cover plate 11 and the actuating member 32 may be a rigid connection, thereby ensuring consistency of movement between the cover plate 11 and the actuating member 32 .

[0067] Optionally, in some embodiments, the connection between the cover 11 and the actuating member 32 may also be a flexible connection. Compared with a rigid connection, the vibration transmission efficiency of the flexible connection is lower, but the flexible connection can reduce the impact of the movement of the actuating member 32 on the cover 11, thereby extending the service life of the cover 11.

[0068] In the display device 1 of the present application, the inner wall of the side panel 211 is provided with support protrusions 2112 extending toward each other. The surface of the support protrusion 2112 facing away from the bottom panel 212 is provided with a buffer layer 22 , and the display body 12 is connected to the buffer layer 22 .

[0069] In this embodiment, the support protrusion 2112 can be used to support the display body 12. To prevent the support protrusion 2112 from blocking the light from the backlight source incident on the display area of ​​the display body 12, the orthographic projection of the support protrusion 2112 on the display body 12 does not overlap with the display area.

[0070] Optionally, to prevent the display body 12 from vibrating relative to the backlight module 20 and causing damage to the display body 12, a buffer layer 22 can be provided on the surface of the support protrusion 2112 on the side close to the display body 12. Similarly, the buffer layer 22 is provided corresponding to the non-display area of ​​the display body 12, thereby preventing the buffer layer 22 from blocking light from the backlight source incident on the display area.

[0071] The buffer layer 22 may be made of a material having a buffering capacity, such as foam, but is not limited thereto.

[0072] In the display device 1 of the present application, the backlight module 20 includes a light source assembly 23 , which is disposed in a receiving cavity formed by the bottom plate 212 and the side plate 211 , and is disposed on a side of the support protrusion 2112 close to the bottom plate 212 .

[0073] In one or more embodiments, the light source assembly 23 can provide a planar light source for the display panel 10. When the backlight module 20 is an edge-lit backlight, the light source assembly 23 can include a light bar and a light guide plate. The light bar includes a plurality of lamp beads, such as LEDs. The light bar is disposed on the peripheral side of the light guide plate, with the light-emitting surfaces of the lamp beads close to the peripheral surface of the light guide plate. The light guide plate can convert the light emitted by the lamp beads into a planar light source, and the light source is incident on the display panel 10 from the backlight surface of the display panel 10.

[0074] Optionally, in some embodiments, the light source assembly 23 may further include a prism sheet, a diffuser sheet, etc. The prism sheet may be disposed on the side of the light guide plate facing away from the bottom plate 212, and the diffuser sheet may be disposed on the side of the prism facing away from the bottom plate 212. The prism sheet can enhance the brightness of the planar light source, while the diffuser sheet can provide more uniform light distribution. The light source assembly 23 may further include a reflector sheet disposed between the light guide plate and the bottom plate 212. The reflector sheet can reflect light from the lower surface of the light guide plate, thereby improving light utilization.

[0075] When the backlight module 20 is a direct-lit backlight, the light source assembly 23 may include a lamp board on which a plurality of lamp beads, such as Mini-LEDs, are arranged.

[0076] In the display device 1 of the present application, as shown in FIG. 1 and FIG. 5 , there are a plurality of excitation components 30 , and each side of the display panel 10 is provided with at least one excitation component 30 .

[0077] In one or more embodiments, the number of excitation members 30 can be set as needed. To achieve a stronger vibration sensation, multiple excitation members 30 can be provided. The positions of the excitation members 30 can be set as needed. For example, the driving member 31 can be provided in the center area of ​​the bottom plate 212 or in the edge area of ​​the bottom plate 212.

[0078] Multiple excitation components 30 can work simultaneously to achieve resonance and enhance resonance. Multiple excitation components 30 can also work individually to provide vibration sensations of various intensities to adapt to different tactile feedback scenarios.

[0079] In some embodiments, the number of the excitation components 30 may be the same as the number of sides of the display panel 10. For example, when the display panel 10 is rectangular, the number of the excitation components 30 may be four, with each excitation component 30 being disposed corresponding to a side of the rectangle.

[0080] When the outer shape of the display panel 10 is irregular, the excitation members 30 may be disposed substantially symmetrically about the center of the display panel 10 .

[0081] It should be understood that in the above embodiment, the maximum vibration generated by the excitation member 30 may be located in the central area of ​​the display panel 10 , and the vibration gradually weakens from the middle area to the edge area of ​​the display panel 10 .

[0082] As shown in Figure 6, a vibration simulation diagram of a display device 1 is shown. Each color represents the magnitude of the vibration, and areas with the same color have the same vibration magnitude. The vibration is strongest in the center area of ​​the display device 1, and gradually decreases from the center area to the edge areas.

[0083] In the display device 1 of the present application, the driving member 31 includes a linear motor, and the actuating member 32 includes a spring pin. When the linear motor receives a driving signal, the linear motor moves in a linear direction, driving the actuating member 32 to move.

[0084] A linear motor consists of a stator and a mover. The stator is typically made of a coil of wire, while the mover is made of a magnetic field-sensing material, such as a magnet. The mover can be a slider, for example. When the coil is energized, it generates a magnetic field that drives the slider to move linearly in a specific direction. The slider can move up and down, left and right, or forward and backward. The direction and speed of the slider's movement can be controlled by the direction and magnitude of the current in the coil. When the slider moves at a certain frequency, it drives the actuator 32 to move at a certain frequency, generating a vibration.

[0085] It should be understood that the magnitude of the vibration sense can be set as needed, for example, by adjusting the number of coil turns or the magnitude of the current passing through the coil, which is not limited in this application.

[0086] In some embodiments, the driving member 31 may also be a rotor motor, which rotates to drive the actuating member 32 to move.

[0087] In one or more embodiments, in order to prevent the magnetic field from affecting the display panel 10 , a magnetic field shielding film may be coated around the excitation member 30 . The magnetic field shielding film may be made of, but not limited to, nanocrystals, etc. The thickness of the nanocrystals may be 0.3 mm.

[0088] In the related art, the excitation component needs to be fixed by a bracket or the like, and the vibration transmission path of the excitation component is the excitation component, the bracket, the outer frame, the support protrusion, the display body, the cover plate, etc. The vibration transmission path is long, and the vibration transmission efficiency is low due to friction and damping. In the present application, the vibration transmission path of the excitation component is the excitation component and the cover plate, and the vibration transmission path is short, which reduces the friction and damping in the vibration transmission, reduces the vibration attenuation transmitted from the moving part to the display panel, and improves the vibration transmission efficiency. At the same time, since the excitation component is directly arranged on the back of the backlight module, the bracket used to fix the excitation component in the related art is omitted, thereby reducing the cost of the display device 1.

[0089] As shown in FIG7 , the present application further provides a display terminal 2 , which includes the above-mentioned display device 1 .

[0090] In one or more embodiments, the display terminal 2 may include a display device 1 and a terminal body 3 , and the display device 1 and the terminal body 3 are combined into one body.

[0091] In one or more embodiments, the display terminal 2 may be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, or a navigator.

[0092] In one or more embodiments, the display terminal 2 may be a vehicle-mounted display product.

[0093] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0094] The above is a detailed introduction to the display device and display terminal provided in the embodiments of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the technical solutions and core ideas of the present application.
