DETAILED DESCRIPTION

[0041] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0042] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0043] With the development of display technology, organic light-emitting diode (OLED) display panels are increasingly widely used in terminal products due to their advantages such as ultra-thinness, bendability, high brightness, high clarity, and high luminous efficiency. Due to the trend of large screens, narrow bezels, and bendability, the protection of display screens has become increasingly prominent. For example, when OLED display panels are applied to bendable terminals (such as foldable display devices), the corresponding OLED display panel will have higher flexibility requirements in order to meet the foldable function, which will lead to a decrease in the drop or impact resistance of the OLED display panel. Folding display devices usually include a display module, a middle frame, a motherboard, and other components, among which the display module is more fragile than other components and is most susceptible to damage when it falls.

[0044] Figure 1 , Figure 2 A related display device is provided, which includes a display module 10 and a middle frame 20. The display module 10 includes a display panel 11 and a cover plate 12, and also includes other laminates such as a composite tape layer. The cover plate 12 is located on the light-emitting side of the display panel 11. In the display module 10, the outer dimensions of the cover plate 12 are larger than the outer dimensions of the display panel 11 and other laminates, and the outer peripheral area of ​​the cover plate 12 is fixed to the middle frame 20. Since there are a large number of fine wirings, light-emitting devices, and water vapor barrier packaging layers on the surface of the display panel 11, these structures are easily damaged and fail when deformed by force. Therefore, compared with other components in the display device, the display module 10 is more easily damaged and has poorer strength.

[0045] After long-term research, the inventors found that during side drop tests and daily use, when the middle frame 20 is squeezed at the side, the most fragile display panel 11 in the display module 10 is easily squeezed, damaged and fails. Therefore, the side impact resistance of existing display devices needs to be improved.

[0046] Based on this, the present application provides a display device and an electronic device solution to solve the above problems.

[0047] Reference Figure 3 , Figure 4 The embodiment of the present application provides a display device 100, which includes a display module 10 and a middle frame 20. The display module 10 includes a display panel 11 and a cover plate 12, and the cover plate 12 is located on the light-emitting side of the display panel 11; the middle frame 20 includes a bearing groove, which is used to accommodate the display module 10. The bearing groove includes a bottom wall 211 and a side wall 212. The bottom wall 211 is located on the backlight side of the display panel 11, and the side wall 212 is spaced from the display panel 11. The side wall 212 is provided with an avoidance groove 30, and the orthographic projection of the display panel 11 on the side wall 212 is located in the avoidance groove 30.

[0048] The display device 100 provided in the embodiment of the present application performs anti-collision and avoidance for the display panel 11 by setting the avoidance groove 30. Specifically, the notch of the avoidance groove 30 faces the display panel 11, and the positive projection of the display panel 11 on the side wall 212 is located in the avoidance groove 30, that is, in the thickness direction of the display panel 11 (the Y direction in the figure), the position of the display panel 11 corresponds to the avoidance groove 30, and the size of the display panel 11 is smaller than the size of the avoidance groove 30. When the display device 100 is deformed by the impact of a lateral external force, the middle frame 20 and the display panel 11 move relative to each other, and the distance between the two gradually decreases. In this process, due to the avoidance groove 30 set on the side wall 212 of the bearing groove, the display panel 11 will enter the avoidance groove 30, thereby preventing the display panel 11 from being squeezed and damaged by the middle frame 20, thereby significantly improving the side impact resistance of the display device 100.

[0049] Continue to refer to Figure 4 In one embodiment, the display module 10 further includes a composite tape layer 13, which is located on the side of the display panel 11 away from the cover plate 12, i.e., the backlight side, and the surface of the composite tape layer 13 away from the display panel 11 is adhesively connected to the bottom wall 211. The composite tape layer 13 has a shock absorbing and buffering function.

[0050] In one embodiment, the display module 10 further includes a support film 15 . The support film 15 is located on a side of the display panel 11 away from the cover plate 12 , specifically between the display panel 11 and the composite tape layer 13 .

[0051] In this embodiment, the display module 10 is a flexible display module, and the display panel 11 is supported, reinforced and protected by the support film 15 to reduce the bending and warping of the display panel 11. The support film 15 is consistent with the outer dimensions of the display panel 11, and the outer periphery of the support film 15 and the display panel 11 protrudes outward from other laminated layers. In the thickness direction of the display panel 11, the groove width of the avoidance groove 30 is greater than the sum of the thickness dimensions of the display panel 11 and the support film 15. When extrusion deformation occurs, the avoidance groove 30 can simultaneously accommodate the corresponding display panel 11 and the support film 15 to enter the groove.

[0052] In other embodiments, the display module 10 is a rigid display module, and the support film 15 may be omitted.

[0053] Preferably, the display module 10 further includes a polarizer 16 and an optical adhesive layer 17 . The polarizer 16 and the optical adhesive layer 17 are located between the display panel 11 and the cover plate 12 . The optical adhesive layer 17 is located between the polarizer 16 and the cover plate 12 .

[0054] Reference Figures 5 to 10 In one embodiment, the display device 100 further includes a support structure 40 , which is located in the avoidance groove 30 , and the support structure 40 supports the avoidance groove 30 at least in the thickness direction of the display panel 11 (Y direction in the figure).

[0055] The display device 100 provided in this embodiment, on the basis of ensuring the side impact resistance, increases the strength of the middle frame 20 by arranging a support structure 40 in the avoidance groove 30 .

[0056] Reference Figure 5 , Figure 6 In one embodiment, the support structure 40 includes a telescopic unit 41 and a distance detection unit 42. The distance detection unit 42 is fixed at one end of the telescopic unit 41 close to the display panel 11. The distance detection unit 42 is used to detect the distance between the display panel 11 and the distance detection unit 42. The telescopic unit 41 moves in the avoidance groove 30 in a direction close to or away from the display panel 11 (X direction in the figure) according to the distance, so that the distance between the distance detection unit 42 and the display panel 11 is greater than a first preset value, so that the support structure 40 can always maintain a certain distance from the display panel 11 to prevent the display panel 11 from being squeezed and damaged.

[0057] Specifically, refer to Figure 5 In the initial state where the display device 100 is not impacted by external force, one end of the support structure 40 close to the display panel 11 is flush with the side wall 212 , and there is a gap between the display panel 11 and the support structure 40 .

[0058] Reference Figure 6When the side of the display device 100 is impacted and the middle frame 20 is deformed (the degree of deformation is not shown in the figure), the distance between the middle frame 20 and the display panel 11 is detected by the distance detection unit 42. When the distance is shortened to a first preset value, the telescopic unit 41 is triggered to shrink, so that the support structure 40 and the display panel 11 can always maintain a certain distance, thereby preventing the display panel 11 from being squeezed and damaged.

[0059] Preferably, the distance detection unit 42 is fixed to one end of the telescopic unit 41 close to the display panel 11. That is, the distance detection unit 42 is located in the support structure 40 at a position closest to the display panel 11. The distance detection unit 42 is fixed to the end of the telescopic unit 41 so that it can directly measure the distance between itself and the display panel 11 in real time as the telescopic unit 41 moves, and controls the telescopic movement of the telescopic unit 41 according to the distance, so that the distance detection unit 42 and the display panel 11 are always out of contact.

[0060] The distance detection unit 42 includes a distance sensor, which may be an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, or the like.

[0061] It is understandable that, in other embodiments, the distance detection unit 42 may also be fixed at other positions in the avoidance groove 30 , and may also detect the dynamic distance between the telescopic end of the telescopic unit 41 and the display panel 11 .

[0062] Reference Figure 7 , Figure 8 In another embodiment, the display device 100 further includes a driving unit 50 and a control unit 60. The driving unit 50 is connected to the telescopic unit 41 to control the telescopic unit 41 to move in the avoidance groove 30 in a direction close to or away from the display panel 11. The distance detection unit 42 and the driving unit 50 are both connected to the control unit 60. The control unit 60 controls the driving unit 50 according to the distance information detected by the distance detection unit 42.

[0063] Continue to refer to Figure 7 , Figure 8 In one embodiment, a metal film 70 is disposed in the avoidance groove 30 , and the metal film 70 is used to transmit the signal of the distance detection unit 42 to the control unit 60 .

[0064] Specifically, the metal film 70 is laid on the inner wall of the avoidance groove 30 to play a conductive role. When the distance detection unit 42 moves in the avoidance groove 30, the signal of the distance detection unit 42 can be transmitted to the control unit 60 through the conductive metal film 70. The control unit 60 can be located in the mainboard of the electronic device, or can be set in a gap position in the electronic device. Similarly, the drive unit 50 can also be set in a gap position in the electronic device.

[0065] Optionally, when the middle frame 20 is made of metal, the metal film 70 may be eliminated, and the middle frame 20 itself may be used to transmit the signal of the distance detection unit 42 to the control unit 60 .

[0066] Continue to refer to Figure 7 , Figure 8 In one embodiment, the telescopic unit 41 includes a telescopic rod, an end of the telescopic rod away from the display panel 11 is a fixed end, fixed to the avoidance groove 30, and electrically connected to the driving unit 50. The distance detection unit 42 is fixed to the telescopic end of the telescopic rod close to the display panel 11. Optionally, a physical connection can be set between the telescopic rod and the driving unit 50.

[0067] Reference Fig. 9 , Fig.10 In another embodiment, the telescopic unit 41 includes a spring, one end of the spring is fixed to the avoidance groove 30 , and the other end of the spring is connected to the distance detection unit 42 , and a groove 81 is provided on the side wall of the avoidance groove 30 .

[0068] The display device 100 further includes a limit drive unit 51 and a limit block 80, wherein the limit drive unit 51 is used to drive the limit block 80 to switch between a first state and a second state. Fig.11 When the stop block 80 is in the first state, the stop block 80 is located in the groove 81. Fig.12 When the limiting block 80 is in the second state, the limiting block 80 at least partially extends out of the groove 81.

[0069] Specifically, when the spring is in the stretched state, the limit block 80 is in the second state, and the limit block 80 is located on the side of the distance detection unit 42 away from the display panel 11, and prevents the distance detection unit 42 from moving in the direction away from the display panel 11; when the distance between the distance detection unit 42 and the display panel 11 is less than or equal to the second preset value, the limit drive unit 51 controls the limit block 80 to be in the first state, so that the distance detection unit 42 can cross the limit block 80 located in the groove 81 and move in the direction away from the display panel 11. The second preset value is greater than or equal to the first preset value. When the distance detection unit 42 detects that the distance between the display panel 11 and the distance detection unit 42 is shortened to the first preset value, the telescopic unit 41 is triggered to perform a contraction action.

[0070] The limiting driving unit 51 for driving the limiting block 80 is the same as the driving unit 50 for driving the telescopic unit 41. Of course, in other embodiments, the limiting driving unit 51 and the driving unit 50 may also be independent driving units.

[0071] Specifically, refer to Fig. 9In the initial state where the display device 100 is not impacted by external force, the middle frame 20 is not deformed, the spring is in a stretched state, and the limit block 80 prevents the distance detection unit 42 from moving in a direction away from the display panel 11 .

[0072] Reference Fig.10 When the side of the display device 100 is impacted and the middle frame 20 is deformed, the driving unit 50 controls the limit block 80 to move in a direction away from the distance detection unit 42, releases the blockage of the limit block 80 on the distance detection unit 42, and under the tension of the spring, the telescopic unit 41 moves in a direction away from the display panel 11.

[0073] In this embodiment, the limiting block 80 moves at least along the thickness direction (the Y direction in the figure) of the display panel 11 to block or clear the distance detection unit 42 .

[0074] In addition to adopting an electric telescopic structure, the telescopic unit 41 and the driving unit 50 of the present application may also adopt a pneumatic or hydraulically driven piston structure, such as a gas spring.

[0075] Reference Figure 4 In one embodiment, the bearing groove of the middle frame 20 includes a first bearing portion 201 and a second bearing portion 202, the display panel 11 is located in the first bearing portion 201, the cover plate 12 is located in the second bearing portion 202, and the orthographic projection of the first bearing portion 201 on the cover plate 12 is located inside the orthographic projection of the second bearing portion 202 on the cover plate 12.

[0076] Optionally, a first adhesive layer 14 is provided between the composite tape layer 13 and the bottom wall 211, and the composite tape layer 13 is adhesively connected to the bottom wall 211 through the first adhesive layer 14. In addition, in the display module 10, the cover plate 12 has the largest outer dimensions, and the outer peripheral area of ​​the cover plate 12 is adhesively connected to the middle frame 20 through the second adhesive layer 18.

[0077] Specifically, the bearing groove of the middle frame 20 is a stepped groove, wherein the first bearing part 201 is a smaller groove in the stepped groove, and the second bearing part 202 is a larger groove in the stepped groove. The first bearing part 201 is sequentially stacked with a first adhesive layer 14, a composite tape layer 13, a supporting film 15, a display panel 11, a polarizer 16, and an optical adhesive layer 17, that is, the display panel 11 is fixed to the first bearing part 201, and the second bearing part 202 of the middle frame 20 fixes the cover plate 12, so that the entire display module 10 is fixed in the bearing groove.

[0078] Based on the same inventive concept, another embodiment of the present application further discloses an electronic device, which includes the display device in the above embodiment.

[0079] Furthermore, the electronic device includes mobile phones, VR devices, computers, televisions, vehicle-mounted display devices, etc.

[0080] The present embodiment provides an electronic device, in which the display device 100 avoids collision with the display panel 11 by setting an avoidance groove 30. When the display device 100 is deformed by a lateral external force impact, the middle frame 20 and the display panel 11 move relative to each other, and the distance between the two gradually decreases. In this process, since the avoidance groove 30 is set on the side wall 212 of the bearing groove, its groove opening faces the display panel 11, and the positive projection of the display panel 11 on the side wall 212 is located in the avoidance groove 30, that is, in the thickness direction of the display panel 11, the size of the display panel 11 is smaller than the size of the avoidance groove 30. Then, the avoidance groove 30 can avoid the display panel 11, thereby preventing the display panel 11 from being squeezed and damaged by the middle frame 20, thereby significantly improving the side impact resistance of the display device 100.
