[0056] 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.

[0057] With the continuous progress of technology, display devices have become an indispensable part of modern work and life. From televisions, computer monitors to remote video devices, the development of display technology has greatly enriched people's visual experience.

[0058] In the related art, as Figure 1 shown, a display device generally includes a display panel 100, a backplane 700, and a middle frame 600. The display panel 100 is used to present images. The backplane is located behind the display panel, and its main function is to support the display panel. At the same time, it may include a circuit board and other electronic components to ensure signal transmission and power supply. The middle frame surrounds the display panel and the backplane. Its design not only needs to ensure the structural stability, but also takes into account aesthetics and portability. Especially when the size of the display panel 100 is large, the middle frame is more likely to deform, which in turn causes the display panel 100 to deform, affecting the display effect of the display panel 100. In the case where the display panel is a touch panel, it will also affect the touch accuracy of the display panel 100.

[0059] In view of this, the present application provides a display device. The display device includes a display panel and a frame structure, which replaces the traditional technical solutions of the backplane and the middle frame. Specifically, the frame structure is used to install the display panel and the rear shell. The frame structure includes multiple layers, and the multiple layers of the frame are connected to each other to form a stable structure, thereby reducing the probability of deformation.

[0060] The following will describe the specific structure of the display device according to the embodiments of the present application with reference to the accompanying drawings.

[0061] Figure 2 is a schematic three-dimensional structure diagram of the display device provided by the embodiment of the present application; Figure 3 is an exploded view of the display device provided by the embodiment of the present application; Figure 4 is a cross-sectional view of the display device provided by the embodiment of the present application;

[0062] Please refer to Figures 2 to 4 shown, the display device 10 according to the embodiment of the present application includes: a display panel 100, a frame structure 200, and a rear shell 300.

[0063] Among them, the display device 10 can be an OLED (Organic Light Emitting Diode) display device, an LED (Light Emitting Diode) display device, a liquid crystal display (LCD) device, etc. The type of the display device 10 is not further limited in this embodiment.

[0064] The display device includes a display panel 100, and the display panel 100 is used to display image information such as characters and images.

[0065] The display panel 100 has a display area (Active Area, AA) and a black matrix area (Black Matrix, BM) surrounding the display area. The display area is used to display images, and the black matrix area is used to block the circuit board and block the background light.

[0066] The display device 10 has a top side, a bottom side, a left side, a right side, a front side, and a rear side. The top side of the display device refers to the side of the display device facing upward, and the bottom side of the display device refers to the side of the display device facing downward. The left side of the display device refers to the side close to the user's left hand when the user faces the display panel 100. Similarly, the right side of the display device refers to the side close to the user's right hand when the user faces the display panel 100.

[0067] Correspondingly, the side of the display device 10 facing the user is the front side, and the side of the display device 10 facing away from the user is the rear side. When the display device 10 is in a standing or hanging state, the absolute height of the upper side of the display device is higher than the absolute height of the lower side.

[0068] The frame structure 200 is disposed on the rear side of the display panel 100 and is located between the display panel 100 and the rear case 300. The frame structure 200 can be used to connect the display panel 100 and the rear case 300. That is to say, the display panel 100 can be connected to the front end face of the frame structure 200, and the rear case 300 can be connected to the rear end face of the frame structure 200.

[0069] After the display panel 100, the rear case 300, and the frame structure 200 are assembled, the display panel 100, the frame structure 200, and the rear case 300 can enclose an installation space 201. Electronic components such as a circuit board can be disposed in the installation space 201.

[0070] Specifically, the frame structure 200 includes a first frame 210, a second frame 220, and a third frame 230. The first frame 210, the second frame 220, and the third frame 230 are sequentially arranged in the direction from the edge to the center of the display panel 100.

[0071] That is, the first frame 210 is located on the outermost side, the second frame 220 is located inside the first frame, and the third frame 230 is located inside the second frame 220. The setting method of the multi-layer structure helps to improve the structural stability of the frame structure 200.

[0072] In addition, the first frame 210 and the third frame 230 are connected through the second frame 220, so that the three form a structurally stable connection body, thereby enabling the frame structure 200 to form a high-strength connection component and reducing the probability of deformation of the display device 10.

[0073] For the display device adopting this embodiment, the display device includes a display panel 100, a frame structure 200, and a rear case 300. Both the display panel 100 and the rear case 300 can be installed on the frame structure 200, and the frame structure 200 is composed of a first frame 210, a second frame 220, and a third frame 230. The above-mentioned frames are connected to each other to form a support. When one of the frames has a tendency to deform, the other frames can play a role in correction, thereby reducing the probability of deformation of the frame structure 200. Due to the high stability of the frame structure 200, the display panel 100 and the rear case 300 connected to the frame structure 200 also have high connection stability, thereby effectively reducing the probability of deformation of the display device 10 and ensuring the service life and operating stability of the display device.

[0074] Furthermore, as Figures 2 to 4 shown, in some embodiments, since the first frame 210, the second frame 220, and the third frame 230 are sequentially arranged in the direction from the edge to the center of the display panel 100, the display panel 100 can be connected to the front end face of the first frame 210 to ensure that the display panel 100 has a larger size. The rear case 300 can be connected to the rear end face of the third frame 230, so that the rear case 300 can not only block the installation space 201, but also reduce the set area of the rear case 300 and lower the production cost.

[0075] As Figures 2 to 4 shown, in some embodiments, the display device 10 further includes a light guide member 400 disposed in the installation space 201. The light guide member 400 can redirect the scattered light to the liquid crystal layer, thereby improving the light utilization efficiency.

[0076] Exemplarily, the light guide member 400 can be disposed on the front end face of the third frame 230. Since the first frame 210 bears the display panel 100, setting the installation position for the light guide member 400 will increase the complexity of the first frame 210.

[0077] The second frame 220 is mainly used to realize the positioning and installation of the first frame 210 and the second frame 220. Setting the light guide member 400 on the second frame 220 will also increase the complexity of the second frame 220, which is not conducive to its processing. Compared with the first frame 210 and the second frame 220, the third frame 230 is located in the innermost layer, and it is most suitable for installing the light guide member 400.

[0078] It should also be noted that, in order to ensure the heat dissipation effect of the display device 10, the light guide member 400 and the display panel 100 can be arranged at intervals. That is to say, there can be an interval between the front end face of the third frame 230 and the front end face of the first frame 210. In this way, when the display panel 100 and the light guide member 400 are respectively installed, a gap is left between them to achieve the effect of rapid heat dissipation.

[0079] Furthermore, in order to enable the display device 10 to be disassembled and repaired quickly, the rear case 300 can be arranged on the third frame 230 in a detachable connection manner. When the inside of the display device needs to be repaired, the rear case 300 can be disassembled to check and repair the display device. Thus, it is not necessary to disassemble the display panel 100 for inspection.

[0080] Exemplarily, the rear case 300 and the third frame 230 can be detachably connected by means of screw connection or snap connection.

[0081] Furthermore, Figure 10 is a schematic diagram of the assembly structure of the frame structure and the rear case of the display device provided by the embodiment of the present application. As Figure 4 and Figure 10 shown, the display device 10 further includes a light emitting member 500, and the light emitting member 500 can provide backlight for the display device 10.

[0082] The light emitting member 500 can be arranged on the rear case 300, and the light emitting part of the light emitting member 500 faces the light guide member 400, so that the light generated by the light emitting member 500 can directly pass through the light guide member 400 and be evenly irradiated onto the display panel after being diffused by the light guide member 400, thereby realizing the uniform distribution of the backlight.

[0083] It should be noted that since the rear case 300 can be disassembled from the third frame 230, setting the light emitting member 500 on the rear case 300 makes the backlight repair of the display device 10 more convenient.

[0084] Exemplarily, the light emitting member 500 can be a light emitting strip, and there can be multiple light emitting strips. The multiple light emitting strips are evenly arranged at intervals on the rear case 300, thereby improving the uniformity of the backlight.

[0085] The specific structure of the frame structure will be described below with reference to the drawings.

[0086] Figure 5 A perspective three-dimensional structural schematic diagram of the frame structure of the display device provided by an embodiment of the present application; Figure 6 is Figure 5 An enlarged structural schematic diagram of part A of the frame structure of Figure 7 Another perspective three-dimensional structural schematic diagram of the frame structure of the display device provided by an embodiment of the present application; Figure 8 is Figure 7 An enlarged structural schematic diagram of part B of the frame structure of Figure 9 The third frame side view of the display device provided by an embodiment of the present application.

[0087] As Figures 4 to 9 shown, in some embodiments, the third frame 230 includes a first mounting member 231 and a second mounting member 232 disposed at an angle to the first mounting member 231. The light guide member 400 is mounted on the front end surface of the second mounting member 232, and the light emitting member 500 is located at the rear side of the second mounting member 232. The inner surface of the second mounting member 232 is an inclined surface 2321, and the inclined surface 2321 is between the light emitting member 500 and the light guide member 400. The light generated by the light emitting member 500 can be reflected to the light guide member 400 via the inclined surface 2321.

[0088] Specifically, the inclined surface 2321 is gradually inclined outward in the direction from the light emitting member to the light guide member 400, showing a trend of gradually spreading outward. With such a setting, the brightness at the edge of the display panel 100 during light emission can be improved, making the brightness transition from the edge to the middle area of the display panel 100 more natural and enhancing the edge image quality of the display panel 100.

[0089] Exemplarily, the angle between the inclined surface 2321 and the display panel 100 is less than 90°. Further, the angle between the inclined surface 2321 and the display panel 100 is between 30° and 85°.

[0090] It should also be noted that the setting positions of the light emitting member and the light guide member of different display devices may be different. Therefore, different inclination angles of the inclined surface 2321 need to be coordinated to achieve the best effect. Since the inclined surface 2321 is provided on the third frame 230, the light adjustment requirements can be met by replacing the third frame 230 with different inclination angles.

[0091] In some embodiments, the pre-positioning of the frame structure can be achieved through a positioning structure, and then the assembly between the first frame 210, the second frame 220, and the third frame 230 is realized by cooperating with fastener connection.

[0092] As Figure 4 and Figure 8As shown, a first positioning structure can be provided between the first frame 210 and the second frame 220, so that the first frame 210 and the second frame 220 are in abutting cooperation through the first positioning structure to positionally connect the first frame 210 and the second frame 220.

[0093] Correspondingly, a second positioning structure can be provided between the second frame 220 and the third frame 230, such that the second frame 220 and the third frame 230 can be in abutting cooperation through the second positioning structure to positionally connect the second frame 220 and the third frame 230.

[0094] Specifically, as Figure 4 shown, the first frame 210 includes a housing 211. The housing 211 is located on the outermost side of the entire frame structure. After the housing 211 is assembled with the second frame 220, they are fixedly connected by fasteners, so that the first frame 210 and the second frame 220 can be firmly connected.

[0095] To facilitate the pre-positioning of the housing 211 and the second frame 220, a first stop portion 212 can be provided on the rear end face of the housing 211. The first stop portion 212 can abut against the second frame 220, thereby pre-positioning the installation positions of the first frame 210 and the second frame 220. That is to say, the first stop portion 212 forms the first positioning structure.

[0096] Further, the second frame 220 includes a baffle 221 and a vertical plate 222 disposed at an angle to the baffle 221. The front end face of the baffle 221 abuts against the rear end face of the housing 211, and the outer end face of the baffle 221 abuts against the first stop portion 212, thereby realizing the pre-positioning of the first frame 210 and the second frame 220.

[0097] Exemplarily, the first stop portion 212 can be a stop rib. The structure of the stop rib is simple and convenient to process, and it can achieve a good limiting effect.

[0098] Further, the third frame 230 includes a first mounting member 231 and a second mounting member 232 disposed at an angle to the first mounting member 231. The rear shell 300 is provided on the first mounting member 231. Specifically, the rear shell 300 is connected to the rear end face of the first mounting member 231. The second mounting member 232 is used to connect the light guide member. Specifically, the light guide member is connected to the front end face of the second mounting member 232.

[0099] The third frame 230 can be pre-positioned and connected to the second frame 220 through the second positioning structure. Specifically, the second positioning structure includes a support portion 223 and a limit portion 224 provided on the vertical plate 222. There is a gap between the support portion 223 and the baffle 221. The first mounting member 231 can extend into this gap and abut against the limit portion 224 located within this gap. At the same time, the support portion 223 can abut and cooperate with the second mounting member 232 to achieve positioning and support of the second mounting member 232.

[0100] Exemplarily, the support portion 223 can be a support bump, and a mating surface 2241 can be provided on the support bump. The angle of the mating surface is set in cooperation with the second mounting member 232, so as to form a stable support for the second mounting member.

[0101] Exemplarily, the limit portion 224 can be a limit protrusion, and the limit protrusion can abut and cooperate with the first mounting member 231, so as to facilitate the installer to quickly assemble the second frame 220 and the third frame 230.

[0102] As Figure 4 and Figure 9 shown, in some embodiments, the baffle 221 of the second frame 220 and the vertical plate 222 form a "T" - shaped structure, that is, the vertical plate 222 is located at the center of the baffle 221 and is perpendicular to the baffle 221. Due to the above - mentioned structure of the second frame 220, the second frame has the function of connecting the first frame and the third frame simultaneously.

[0103] Specifically, the baffle 221 can abut against the housing 211 of the first frame 210. The display device 10 further includes a first fastener 240. The first fastener 240 passes through the housing 211 and the baffle 221 to fixedly connect the first frame 210 and the second frame 220.

[0104] At the same time, the baffle 221 can also abut against the first mounting member 231 of the second frame 220. The display device 10 further includes a second fastener 250. The second fastener 250 passes through the baffle 221 and the first mounting member 231 to fixedly connect the second frame 220 and the third frame 230.

[0105] It should also be noted that each of the first frame 210, the second frame 220, and the third frame 230 is formed by connecting four beam bodies end - to - end. The connection manner of the beam bodies can refer to the splicing - type or butt - type installation manner in the prior art for connection.

[0106] In addition, the present application also provides a display device 10.
