Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0030] The present application provides a display panel 1. Please also refer to Figure 1 and Figure 2 , Figure 1 is a top - view schematic diagram of the display panel provided by an embodiment of the present application; Figure 2 is Figure 1Schematic cross-sectional view along line I-I. The display panel 1 includes a backplane 11, a display component 12, a front frame 13, and a driving component 14. The display panel 1 has a display area 1a and a non-display area 1b. The non-display area 1b surrounds the display area 1a. The display component 12 is disposed on one side of the backplane 11 and within the display area 1a. The backplane 11 includes a body 111, a first extension portion 112 and a second extension portion 113 that extend from the body 111 and are spaced apart. The first extension portion 112 and the second extension portion 113 are disposed within the non-display area 1b and extend toward the display component 12 along the stacking direction of the display component 12 and the backplane 11. The second extension portion 113 is adjacent to the display component 12. The front frame 13 is disposed within the non-display area 1b and includes a frame body 131 and a plurality of first limiting portions 132 that extend from the frame body 131 and extend toward the backplane 11. A plurality of first engaging portions 114 are provided on one side of the first extension portion 112 and / or the second extension portion 113 adjacent to the front frame 13. The plurality of first limiting portions 132 and the plurality of first engaging portions 114 cooperate with each other to fix the backplane 11 and the front frame 13. At least a part of the driving component 14 is disposed within the receiving space formed by the enclosure of the backplane 11 and the front frame 13.

[0031] It should be noted that the driving component 14 obtains a display signal and transmits it to the display component 12 to drive the display component 12 to work, thereby realizing the screen display function of the display panel 1. Usually, in order to avoid the driving component 14 blocking the display component 12, at least a part or all of the driving component 14 is disposed outside the display component 12. In this embodiment, the driving component 14 is disposed within the receiving space formed by the enclosure of the backplane 11 and the front frame 13. In the related art, the backplane 11 and the front frame 13 are adhesively fixed using double-sided tape or optical glue. This setting method makes the assembly time of the display panel 1 long, and when the driving component 14 fails, it is difficult to disassemble the backplane 11 and the front frame 13 to repair the driving component 14. It can be understood that in this embodiment, the first limiting portion 132 and the first engaging portion 114 are separate bodies, which facilitates the disassembly of the backplane 11 and the front frame 13 to repair the driving component 14, thereby reducing the difficulty of repairing the display panel 1.

[0032] Specifically, the number and the set positions of the first limiting portions 132 and the first mating portions 114 correspond one by one. The first limiting portions 132 and the first mating portions 114 may be in a snap-fit structure. For example, the first limiting portions 132 extend into the first mating portions 114 for snap-fixing. They may also be in a magnetic attraction fit. For example, the first limiting portions 132 and the first mating portions 114 have magnetism to generate a mutually attracting magnetic force for fixing. It can be understood that in other possible embodiments, the first limiting portions 132 and the first mating portions 114 may also be other combinations, as long as it does not affect the mutual cooperation of the first limiting portions 132 and the first mating portions 114 to fix the back plate 11 and the front frame 13, and the present application does not limit this; the first mating portions 114 may be provided on the first extension portion 112, or the second extension portion 113, or both on the first extension portion 112 and the second extension portion 113. It can be understood that in other possible embodiments, the first limiting portions 132 and the first mating portions 114 may also be provided at other positions, as long as it does not affect the mutual cooperation of the first limiting portions 132 and the first mating portions 114 to fix the back plate 11 and the front frame 13, and the present application does not limit this.

[0033] In this embodiment, at least a part of the driving component 14 is embedded in the first extension portion 112, so as to fix the driving component 14 in the accommodation space, and the driving component 14 is spaced from the first mating portion 114 on the first extension portion 112, so as to prevent the driving component 14 from affecting the mutual cooperation of the first limiting portion 132 and the first mating portion 114 on the first extension portion 112. The driving component 14 adopts a flat circuit design, so as to reduce the width of the driving component 14 in the direction perpendicular to the stacking direction, and prevent the driving component 14 from affecting the mutual cooperation of the first limiting portion 132 and the first mating portion 114 on the second extension portion 113.

[0034] It can be understood that in this embodiment, on the premise of not affecting the thickness of the display panel 1, the back plate 11 and the front frame 13 are fixed by the mutual cooperation of a plurality of the first limiting portions 132 and a plurality of the first mating portions 114, and the assembly is relatively simple. At the same time, the first limiting portions 132 and the first mating portions 114 are separated, which is convenient for disassembling the back plate 11 and the front frame 13, and reduces the difficulty of repairing the display panel 1.

[0035] In a possible embodiment, please refer to Figure 3 , Figure 3The first limiting portion 132 and the first matching portion 114 are matched in shape so that the first limiting portion 132 and the first matching portion 114 are clamped and fixed.

[0036] In this embodiment, the materials of the first limiting portion 132 and the first matching portion 114 have a certain elasticity. When the first limiting portion 132 enters the first matching portion 114, the first limiting portion 132 opens the entrance of the first matching portion 114. After the first limiting portion 132 at least partially enters the first matching portion 114, the shapes of the first limiting portion 132 and the first matching portion 114 match, and the entrance of the first matching portion 114 rebounds due to elasticity, so that the first limiting portion 132 is engaged with the first matching portion 114.

[0037] It is understandable that in other possible implementations, the first limiting portion 132 and the first matching portion 114 may also be other structures that are mutually engaged, and the present application does not impose any limitation on this.

[0038] In a possible implementation, please refer to Figure 4 , Figure 4 The cross-sectional view of the display panel provided in one embodiment of the present application. The front frame 13 is provided with a plurality of second matching portions 133, the first extension portion 112 and / or the second extension portion 113 extend to the second matching portions 133, and the first extension portion 112 and / or the second extension portion 113 cooperate with the second matching portions 133 to fix the back plate 11 and the front frame 13.

[0039] Specifically, the difference between this embodiment and the previous embodiment is that the first extension portion 112 and / or the second extension portion 113 extend to the second matching portion 133, thereby cooperating with the second matching portion 133, and fixing the back plate 11 and the front frame 13. In other words, in the previous embodiment, the first limiting portion 132 enters the first matching portion 114 and is fixedly engaged with the first matching portion 114, while in this embodiment, the first extension portion 112 and / or the second extension portion 113 extend to the second matching portion 133, enter the second matching portion 133, and are fixedly engaged with the second matching portion 133. It can be understood that the way in which the first extension portion 112 and / or the second extension portion 113 cooperate with the second matching portion 133 is similar to the way in which the first limiting portion 132 cooperates with the first matching portion 114, and will not be repeated here.

[0040] It can be understood that in other possible implementation manners, it may be that the first limiting portion 132 and the first mating portion 114 cooperate to fix the back plate 11 and the front frame 13; it may also be that the first limiting portion 132 and the first mating portion 114 cooperate, and at the same time the first extending portion 112 and / or the second extending portion 113 and the second mating portion 133 cooperate to fix the back plate 11 and the front frame 13; the present application does not limit this.

[0041] In a possible implementation manner, please refer to Figure 5 , Figure 5 for Figure 1 the schematic cross-sectional view along line II-II in

[0042] Specifically, in combination with Figure 1 shown, the display panel 1 further includes a first end 1c, a second end 1d, a third end 1e and a fourth end 1f. The first end 1c and the third end 1e are oppositely arranged, the second end 1d and the fourth end 1f are oppositely arranged, the first end 1c is bent and connected to the second end 1d and the fourth end 1f respectively, and the third end 1e is bent and connected to the second end 1d and the fourth end 1f respectively. It can be understood that in this implementation manner, the fixing strength of the first limiting portion 132 and the first mating portion 114 is weaker than that of the limiting member 15 and the second mating portion 133. The first limiting portion 132 and the first mating portion 114 are usually arranged in the middle part of the first end 1c, the second end 1d, the third end 1e and the fourth end 1f. This setting method can reduce the deformation of the front frame 13 and the back plate 11 corresponding to the first end 1c, the second end 1d, the third end 1e and the fourth end 1f during the assembly or disassembly of the front frame 13 and the back plate 11. For the portions where the first end 1c, the second end 1d, the third end 1e and the fourth end 1f are bent and connected, the limiting member 15 and the second mating portion 133 with higher fixing strength are required to cooperate for fixing, so as to further fix the front frame 13 and the back plate 11.

[0043] It can be understood that as Figure 5As shown, the driving component 14 is also arranged at an interval from the limiting member 15 to avoid affecting the cooperation between the limiting member 15 and the second engaging portion 133. The surface of the side of the limiting member 15 facing away from the front frame 13 is flush with the surface of the back plate 11, so that better assembly can be carried out during subsequent assembly.

[0044] In this embodiment, the limiting member 15 is a bolt, the second engaging portion 133 is a threaded hole, and threads corresponding to the limiting member 15 can also be provided in the first extension portion 112 and / or the second extension portion 113, so that the limiting member 15 can penetrate through the first extension portion 112 and / or the second extension portion 113 to the second engaging portion 133. It can be understood that in other possible embodiments, the limiting member 15 and the second engaging portion 133 can also be other combinations, as long as it does not affect the detachable connection of the limiting member 15 to the second engaging portion 133 and facilitates the assembly and disassembly of the back plate 11 and the front frame 13, the present application does not limit this.

[0045] In a possible embodiment, please refer to Figure 6 , Figure 6 which is a schematic cross-sectional shape diagram of the first limiting portion provided by an embodiment of the present application. The cross-sectional shape of the first limiting portion 132 includes any one or more of a T shape, a trapezoid, and a cross shape.

[0046] Specifically, as Figure 6 shown, from left to right, the cross-sectional shapes of the first limiting portion 132 are a T shape, a trapezoid, and a cross shape in sequence. It can be understood that different cross-sectional shapes of the first limiting portion 132 all include a first portion 1321 and a second portion 1322, the first portion 1321 is connected to the second portion 1322, and the width of the second portion 1322 is greater than the width of the first portion 1321. Since the shapes of the first limiting portion 132 and the first engaging portion 114 match, when the first portion 1321 feeds the second portion 1322 into the first engaging portion 114, the second portion 1322 can be clamped and fixed with the first engaging portion 114.

[0047] It can be understood that in other possible embodiments, the cross-sectional shape of the first limiting portion 132 can also be other shapes, as long as it does not affect the cooperation between the first limiting portion 132 and the first engaging portion 114 to fix the back plate 11 and the front frame 13, the present application does not limit this.

[0048] In a possible embodiment, please refer to again Figure 2, the display panel 1 further includes a support member 16, a fixing member 17, and a buffer member 18. The support member 16 is fixedly connected to the second extension portion 113 through the fixing member 17. The display assembly 12 includes a backlight module 121 and a display module 122. The backlight module 121 is disposed on the backplane 11, and the support member 16 is disposed on a side of the backlight module 121 away from the backplane 11 and supports the display module 122 through the buffer member 18.

[0049] It should be noted that in the related art, the display panel 1 further includes a middle frame for supporting the backlight module 121 and the display module 122. In this embodiment, the middle frame in the related art is removed, and the display panel 1 provided in the present application uses the support member 16 to support the display module 122. Since the support member 16 is cleverly fixed to the second extension portion 113 through the fixing member 17, the support member 16 replaces the middle frame in the related art, and the overall occupied space is small, thereby reducing the thickness of the display panel 1 in the stacking direction.

[0050] In this embodiment, the fixing member 17 is a bolt, and a screw hole is formed at a corresponding position of the second extension portion 113, and the fixing member 17 passes through the screw hole so that the support member 16 is fixed to the second extension portion 113. It can be understood that in other possible embodiments, the support member 16 can also be fixed to the second extension portion 113 by other means, and the present application does not limit this.

[0051] It can be understood that the material of the buffer member 18 is relatively soft to prevent the display module 122 from being damaged when the support member 16 supports the display module 122 through the buffer member 18.

[0052] In a possible embodiment, please refer to again Figure 2 , the driving assembly 14 includes a first circuit board 141 and a chip-on-film 142. The display module 122 includes a first display screen 1221. The first circuit board 141 is electrically connected to the first display screen 1221 through the chip-on-film 142.

[0053] Specifically, the first circuit board 141 is used to receive a first display signal. At least one chip circuit is provided on the chip-on-film 142 so that the chip-on-film 142 receives the first display signal and controls the first circuit board 141 according to the first display signal to drive the pixel units on the first display screen 1221 to work.

[0054] It can be understood that in this embodiment, since the first circuit board 141 is electrically connected to one side of the first display screen 1221 perpendicular to the stacking direction through the flip chip film 142, it is avoided to bend the first circuit board 141 to the side of the backplane 11 away from the first display screen 1221, thereby saving the thickness of the display panel 1 in the stacking direction.

[0055] In a possible implementation manner, please refer to Figure 7 , Figure 7 which is a schematic cross-sectional view of a display panel provided in another embodiment of the present application. The driving assembly 14 includes a first circuit board 141, a second circuit board 143, a connecting member 144 and a flip chip film 142. The first circuit board 141 and the second circuit board 143 are connected through the connecting member 144. The display module 122 includes a first display screen 1221 and a second display screen 1222. The first circuit board 141 is electrically connected to the first display screen 1221 through the flip chip film 142, and the second circuit board 143 is electrically connected to the second display screen 1222 through the flip chip film 142.

[0056] It should be noted that in this embodiment, the display panel 1 adopts a dual display screen, that is, the first display screen 1221 and the second display screen 1222 are used for display. Among them, the first circuit board 141 obtains a first display signal and transmits it to the first display screen 1221 to drive the first display screen 1221 to realize the display of the picture. The second circuit board 143 obtains a second display signal and transmits it to the second display screen 1222 to control the light emitted by the backlight module 121. The backlight module 121 provides light for display to the first display screen 1221 and the second display screen 1222.

[0057] Specifically, the first circuit board 141 is used to receive a first display signal, the second circuit board 143 is used to receive a second display signal, and at least one chip circuit is provided on the flip chip film 142 so that the flip chip film 142 receives the first display signal or the second display signal, controls the first circuit board 141 according to the first display signal, controls the second circuit board 143 according to the second display signal, drives the pixel units of the first display screen 1221 to work, and controls the light emitted by the backlight module 121 for the second display screen 1222.

[0058] In this embodiment, the connecting member 144 is disposed between the first circuit board 141 and the second circuit board 143 and is used to connect and support the first circuit board 141 and the second circuit board 143. It can be understood that the connecting member 144 is made of a material with a relatively soft texture such as rubber, so as to avoid damaging the first circuit board 141 and the second circuit board 143 when supporting the first circuit board 141 or the second circuit board 143. It can be understood that the display panel 1 may be bent. The first circuit board 141 and the second circuit board 143 are connected by the connecting member 144, which can avoid the interference between the first circuit board 141 and the second circuit board 143 when the display panel 1 is bent.

[0059] It can be understood that the fixing method of the backplane 11 and the front frame 13 provided in the present application can be applied not only to a single display screen, that is, in the embodiment with only the first display screen 1221 and the first circuit board 141, but also to a dual display screen, that is, in the embodiment where the display module 122 includes the first display screen 1221 and the second display screen 1222, and the driving component 14 includes the first circuit board 141 and the second circuit board 143. The present application does not limit this.

[0060] In a possible implementation manner, please refer to again Figure 2 , the backlight module 121 includes a light source 1211 and an optical film 1212. The light source 1211 is a direct - type mini LED, and the optical film 1212 is a QD film.

[0061] It should be noted that since the light source 1211 adopts mini LED technology, the direct - type layout method does not increase the thickness of the display panel 1 in the stacking direction. At the same time, the optical film 1212 adopts a quantum dot film (Quantum Dots film, QD film). The optical film 1212 and the blue - light mini LED in the light source 1211 cooperate to synthesize white light, effectively increasing the optical color gamut value to 105%. At the same time, the light source 1211 is a mini LED, which can cooperate with the first display screen 1221 and / or the second display screen 1222 to ensure the display effect of the display panel 1.

[0062] In this embodiment, the backlight module 121 further includes a substrate 1213 and an optical lens 1214. The substrate 1213 is used to carry the light source 1211, and the optical lens 1214 is disposed on the side of the optical film 1212 away from the light source 1211. The optical lens 1214 includes a diffusion plate 1215, a prism sheet 1216, a diffusion film 1217, etc., which are devices that can change the direction of the light emitted by the light source 1211.

[0063] It can be understood that in other possible embodiments, other types of devices or materials may also be selected for the light source 1211 and the optical film 1212, and the present application does not limit this.

[0064] In a possible embodiment, please refer to Figure 8 , Figure 8 which is a schematic cross-sectional view of a display panel provided in another embodiment of the present application. The display panel 1 further includes a heat dissipation member 19. A heat conduction portion 1131 is provided in a portion of the second extension portion 113 corresponding to the light source 1211 in a direction perpendicular to the stacking direction. The heat dissipation member 19 is disposed in the accommodation space and at least partially disposed in the heat conduction portion 1131.

The display panel 1 further includes a heat dissipation member 19, and the heat dissipation member 19 is disposed on the surface of the frame body 131 away from the back plate 11.

[0068] It should be noted that since there are many electronic components provided on the driving component 14 and it also needs to work for a long time to maintain the display function of the display panel 1, a relatively large amount of heat will also be generated. In this embodiment, the heat dissipation member 19 is disposed on a surface of the frame body 131 facing away from the back plate 11, so that the heat generated by the driving component 14 can be conducted to the heat dissipation member 19 through the frame body 131 for heat dissipation. It can be understood that the frame body 131 can be made of a material with good heat conduction performance.
