[0043] This application provides a display device for displaying images on devices such as televisions or computers.

[0044] Please refer to Figures 1 to 5The display device 100 of this application embodiment includes a rear shell 10, a rear panel 40, and a display module 20. The rear shell 10 includes a first frame 12 and a support plate 11 disposed within the first frame 12. The first frame 12 and the support plate 11 form a first groove 13 along their respective thickness directions Y. The display module 20 is connected to the support plate 11 and is completely located within the first groove 13. The display module 20 includes a display panel 24. The rear panel 40 is connected to the side of the support plate 11 facing away from the display module 20, and the side of the rear panel 40 facing away from the support plate 11 is a plane.

[0045] The support plate 11 of the rear shell 10 supports the rear panel 40 and the display module 20. In the thickness direction Y of the support plate 11, the first frame 12 extends from the support plate 11 toward one side of the support plate 11, and the depth direction of the first groove 13 is also in the thickness direction Y of the support plate 11. For an example, please refer to... Figure 4 The support plate 11 is a rectangular plate. Optionally, the support plate 11 can also be a circular plate or other polygonal plates, etc.

[0046] The display module 20 is completely located within the first recess 13, meaning that multiple sides of the display module 20 are completely shielded by the first frame 12. The first frame 12 protects multiple sides of the display module 20 along the Y-direction perpendicular to the thickness of the support plate 11. The display panel 24 is the foremost part of the display module 20, located within the first recess 13, and is used to display an image. Optionally, the display panel 24 can be liquid crystal glass, organic light-emitting diodes, etc. Optionally, the display panel 24 can be parallel to the support plate 11, resulting in a smaller overall thickness of the display device 100. For an example, please refer to... Figure 5 The display panel 24 is a rectangular panel. Alternatively, the display panel 24 can also be a circular panel or other polygonal panels.

[0047] The side of the support plate 11 facing away from the display module 20 refers to the side of the support plate 11 facing away from the display module 20 along its own thickness direction Y. The rear panel 40 and the display module 20 are located on opposite sides of the support plate 11 along its own thickness direction Y. The side of the rear panel 40 facing away from the support plate 11 refers to the side of the rear panel 40 facing away from the support plate 11 along its thickness direction Y. This side of the rear panel 40 facing away from the support plate 11 is also the back of the display device 100, and the rear panel 40 is used to separate the internal structure of the display device 100 from the external environment. Optionally, the side of the rear panel 40 facing away from the support plate 11 can be parallel to the support plate 11, resulting in a smaller thickness for the display device 100. Optionally, the side of the rear panel 40 facing away from the support plate 11 can also form a small angle with the support plate 11. For an example, please refer to... Figure 4 The rear panel 40 is a rectangular plate and parallel to the support plate 11. Optionally, the rear panel 40 can also be a circular plate or other polygonal plates, etc.

[0048] The beneficial effects of this application embodiment are as follows: By setting the first frame 12 and the support plate 11 to form a first groove 13, and completely placing the display module 20 within the first groove 13, the first frame 12 of the rear shell 10 shields and protects the sides of the display module 20, eliminating the need for a front frame. Compared to a curved back surface for the display device, setting the side of the rear panel 40 away from the support plate 11 to a flat surface simplifies the structure of the rear panel 40. In summary, the overall structure of the display device 100 is simpler. This application embodiment can solve the technical problem of a complex overall structure for the display device, and the flat back surface of the display device 100 is more aesthetically pleasing.

[0049] In some embodiments, please refer to Figures 2 to 4 The first frame 12 and the support plate 11 form a second groove 14 along their own thickness direction Y, away from the side of the rear panel 40, and the rear panel 40 is completely located in the second groove 14.

[0050] In the thickness direction Y of the support plate 11, the first frame 12 extends to the side of the support plate away from the display panel, and the depth direction of the second groove 14 is the same as the depth direction of the first groove 13.

[0051] With the rear panel 40 completely located within the second recess 14, the first frame 12 can completely cover and protect multiple sides of the rear panel 40. Optionally, in the thickness direction Y of the support plate 11, the side of the rear panel 40 facing away from the support plate 11 can be flush with the first frame 12, making the back of the display device 100 flatter.

[0052] The beneficial effects of this embodiment are that the first frame 12 can position the rear panel 40 on the support plate 11, making it convenient to quickly install the rear panel 40 into the preset position. Moreover, the first frame 12 can completely cover and protect multiple sides of the rear panel 40.

[0053] In some embodiments, please refer to Figures 2 to 5 The display device 100 further includes a main board 30 disposed between the support plate 11 and the display panel 24. The display module 20 further includes a back plate 21, a heat sink 22, and a light guide assembly 23 disposed sequentially on the side of the main board 30 near the display panel 24. The back plate 21 is fixed to the support plate 11, and the main board 30 and the heat sink 22 are respectively connected to the two sides of the back plate 21. A portion of the back plate 21 is recessed towards the light guide assembly 23 and forms a first mounting groove 213, in which the main board 30 is located. A portion of the back plate 21 is recessed towards the support plate 11 and forms a second mounting groove 214, in which the heat sink 22 is located.

[0054] The motherboard 30, backplate 21, heat sink 22 and light guide assembly 23 are arranged between the support plate 11 and the display panel 24.

[0055] The motherboard 30 is electrically connected to the display module 20. The motherboard 30 can receive signals transmitted from external devices and control the operation of the display module 20 according to the signals from the external devices.

[0056] The backplate 21 supports the motherboard 30 and the heatsink 22. The motherboard 30 and the heatsink 22 are fixed to the support plate 11 by the backplate 21. Optionally, the edge of the backplate 21 is fixedly connected to the support plate 11 by screws. The thickness direction of the backplate 21 is the same as or substantially the same as the thickness direction Y of the support plate 11.

[0057] The display device 100 is equipped with a light source, and the light guide assembly 23 is used to receive the light emitted by the light source and distribute the light evenly before directing it onto the display panel 24. The light source can be a point light source or a surface light source, etc.

[0058] A portion of the backplate 21 is recessed along the thickness direction Y of the support plate 11 to guide the light assembly 23 and form a first mounting groove 213. The main board 30 includes a printed circuit board and other components connected to the printed circuit board. The thickness direction of the printed circuit board is the same as or substantially the same as the thickness direction Z of the support plate 11. The printed circuit board of the main board 30 is located within the first mounting groove 213 and connected to the groove wall of the first mounting groove 213. Optionally, the main board 30 is fixedly connected to the backplate 21 by screws.

[0059] A portion of the back plate 21, excluding the first mounting groove 213, is recessed along the thickness direction Y of the support plate 11 to form a second mounting groove 214. A heat sink 22 is connected to the wall of the second mounting groove 214. The thickness direction of the heat sink 22 is the same as or substantially the same as the thickness direction of the rear panel 40. The heat sink 22 contacts the light guide assembly 23, accelerating heat dissipation from the light guide assembly 23. Optionally, the heat sink 22 is fixedly connected to the back plate 21 by screws. On a plane perpendicular to the thickness direction Y of the support plate 11, the orthographic projection of the second mounting groove 214 is completely offset from the orthographic projection of the first mounting groove 213, and the orthographic projection of the heat sink 22 is completely offset from the orthographic projection of the motherboard 30.

[0060] The beneficial effect of this embodiment is that, in the thickness direction Y of the support plate 11, the first mounting groove 213 and the second mounting groove 214 are respectively recessed in different directions, and the motherboard 30 and the heat sink 22 are respectively disposed in the first mounting groove 213 and the second mounting groove 214. Therefore, in the thickness direction Y of the support plate 11, the overall thickness of the motherboard 30, the heat sink 22 and the back plate 21 is less than the sum of the thickness of the motherboard 30, the heat sink 22 and the back plate 21, making the display device 100 thinner.

[0061] In some embodiments, the support plate 11 has a second through hole 116 extending along its thickness direction Y. The rear panel 40 has a third through hole 41 extending along the thickness direction Y of the support plate 11. The main board 30 includes an interface 31, which extends from the side of the support plate 11 away from the rear panel 40 through the second through hole 116 into the third through hole 41. In the thickness direction Z of the support plate 11, the third through hole 41 is directly opposite the second through hole 116.

[0062] Interface 31 can be a power interface, a High Definition Multimedia Interface (HDMI), etc., and the motherboard 30 can connect to external devices of the display device 100 through the power interface 31. Optionally, multiple interfaces 31 can be provided, and multiple second through holes 116 corresponding to interfaces 31 can be provided.

[0063] Interface 31 extends from the side of the support plate 11 away from the rear panel 40 through the second through hole 116 into the third through hole 41. That is, the printed circuit board of the motherboard 30 is located on the side of the support plate 11 away from the rear panel 40, and the interface 31 extends from the printed circuit board through the second through hole 116 into the third through hole 41. Devices outside the display device 100 can connect to interface 31 from the back of the display device 100.

[0064] In the thickness direction Y of the support plate 11, the sum of the dimensions of the interface 31, the support plate 11, and the rear panel 40 is less than the sum of the dimensions of the interface 31 and the rear panel 40. Optionally, the interface 31 can be flush with the side of the rear panel 40 facing away from the support plate 11. In this case, the sum of the dimensions of the interface 31, the support plate 11, and the rear panel 40 in the thickness direction Y of the support plate 11 is equal to the dimension of the interface 31, making the display device 100 thinner.

[0065] In some embodiments, please refer to Figure 2 and Figure 3 In the thickness direction Y of the support plate 11, a portion of the edge of the back plate 21 is concave to the support plate 11, and a portion of the edge of the support plate 11 is concave to the back plate 21 and contacts and connects with the concave edge of the back plate 21 to the support plate 11. A gap is provided between the other part of the back plate 21 and the support plate 11 to facilitate the installation of the main board 30 and other components between the back plate 21 and the support plate 11.

[0066] In some embodiments, please refer to Figures 6 to 9 The first frame 12 also includes a plurality of side plates 121 connected to the edge of the support plate 11. A lead wire gap 90 is provided between the display panel 24 and one of the side plates 121; the display device 100 also includes a decorative strip 60 connected to the side of the display panel 24 facing away from the light guide assembly 23, the decorative strip 60 being used to cover the lead wire gap 90.

[0067] Multiple side plates 121 are respectively connected to different sides of the support plate 11 along the direction Y perpendicular to its own thickness. The length direction of each side plate 121 is the same as the length direction of each edge of the support plate 11, and the multiple side plates 121 are connected end to end to form a closed loop first frame 12. Each side plate 121 is perpendicular to the support plate 11, and the width direction of the side plate 121 is consistent with the thickness direction Y of the support plate 11. For an example, please refer to [reference needed]. Figure 4 The four side plates 121 form a rectangle, with two side plates 121 connected to the two ends of the support plate 11 along its length direction X, and the other two side plates 121 connected to the two ends of the support plate 11 along its height direction Z.

[0068] The display panel 24 needs to be connected to the circuit board such as the driver board 26 via conductive structures such as flexible circuit boards. The lead gap 90 is used to accommodate the conductive structure, allowing the conductive structure of the display panel 24 to pass through the lead gap 90 and connect to the circuit board. A lead gap 90 is provided between the display panel 24 and a side plate 121, and the length direction of the lead gap 90 is consistent with the length direction of the side plate 121.

[0069] The side of the display panel 24 facing away from the light guide assembly 23 is the front of the display device 100. A decorative strip 60 is attached to this side of the display panel 24 to shield the lead wire gap 90 on the front of the display device 100. The length direction of the decorative strip 60 is consistent with the length direction of the lead wire gap 90. For example, ... Figures 7 to 9 As shown, there is a lead wire gap 90 between the display panel 24 and the side panel 121 below the display panel 24, and a decorative strip 60 is connected to the lower side of the display panel 24. The decorative strip 60 can be fixed only to the display panel 24, or it can be fixed to both the display panel 24 and the back cover 10. The decorative strip 60 can be bonded to the display panel 24 and the back cover 10 by double-sided tape or adhesive application. Optionally, the decorative strip 60 can be a stainless steel sheet, a polycarbonate (PC) sheet, etc.

[0070] The beneficial effects of this application embodiment are as follows: setting the lead wire gap 90 facilitates the connection of the conductive structure connected on the display panel 24 to the circuit board in the display device 100. Setting the decorative strip 60 can cover the lead wire gap 90, preventing external dust and other debris from entering the display device 100, and setting the decorative strip 60 can make the display device 100 more aesthetically pleasing.

[0071] In some embodiments, please refer to Figure 4 and Figure 5The display module 20 also includes a drive board 26 connected to the back plate 21 on the side facing away from the heat sink 22. The drive board 26 is electrically connected to the motherboard 30 and the display panel 24. On the surface of the support plate 11 along its own thickness direction Y, the orthographic projection of the drive board 26 coincides with the orthographic projection of the heat sink 22. The support plate 11 is provided with a third receiving hole 111, and some components of the drive board 26 are located in the third receiving hole 111.

[0072] The driver board 26 is used to receive signals from the motherboard 30 and drive the display panel 24 to display images according to the signals from the motherboard 30. The driver board 26 is located on the side of the back plate 21 away from the heat sink 22, that is, the driver board 26 and the motherboard 30 are located on the same side of the back plate 21.

[0073] The thickness of the motherboard 30 is greater than the sum of the thicknesses of the heat sink 22 and the driver board 26. On the surface of the support plate 11 along its thickness direction Y, the orthographic projection of the driver board 26 partially coincides with the orthographic projection of the heat sink 22. That is, the overall thickness of the driver board 26, backplate 21, and heat sink 22 is less than the overall thickness of the motherboard 30 and backplate 21. The overall thickness of the driver board 26, motherboard 30, backplate 21, and heat sink 22 is equal to the overall thickness of the motherboard 30, backplate 21, and heat sink 22. The driver board 26 does not increase the thickness of the display device 100. On the surface of the support plate 11 along its thickness direction Y, the orthographic projections of the driver board 26 and motherboard 30 are spaced apart. The surface of the support plate 11 along its thickness direction Y is perpendicular to the thickness direction Y of the support plate 11.

[0074] The third receiving hole 111 penetrates the support plate 11 along the thickness direction Y. Some components of the drive plate 26 are located in the third receiving hole 111. Therefore, in the thickness direction Y of the support plate 11, the overall size of the drive plate 26 and the support plate 11 is smaller than the sum of the size of the drive plate 26 and the size of the support plate 11, and the overall thickness of the drive plate 26 and the support plate 11 is relatively small.

[0075] The beneficial effects of this embodiment are as follows: On the surface of the support plate 11 along its thickness direction Y, the orthographic projection of the drive plate 26 partially coincides with the orthographic projection of the heat sink 22. By utilizing the space occupied by the motherboard 30 and the back plate 21 in the thickness direction Y of the support plate 11 to place the drive plate 26, the overall thickness of the motherboard 30, back plate 21, drive plate 26, and heat sink 22 is smaller, resulting in a thinner display device 100. Furthermore, since some components of the drive plate 26 are located in the third receiving hole 111, the overall thickness of the drive plate 26 and the support plate 11 is smaller, further contributing to a thinner display device 100.

[0076] In some embodiments, please refer to Figure 5 and Figure 10The display module 20 also includes a light strip 25, which is located on one side of the light guide assembly 23 along the direction perpendicular to its own thickness, and part of the heat sink 22 is bent to the side of the light strip 25 away from the light guide assembly 23.

[0077] The light strip 25 extends along one edge of the light guide assembly 23. The light strip 25 emits light into the light guide assembly 23, which enables the light emitted by the light strip 25 to be evenly distributed within the assembly. A portion of the heat sink 22 is bent to the side of the light strip 25 facing away from the light guide assembly 23, meaning the heat sink 22 contacts the side of the light strip 25 facing away from the light guide assembly 23, thus accelerating heat dissipation from the light strip 25. For example, the light strip 25 is positioned below the light guide assembly 23, and the bottom of the heat sink 22 is bent upwards to the bottom surface of the light strip 25.

[0078] The beneficial effects of this application embodiment are as follows: compared with point light source, the light strip 25 can emit light at multiple positions along its own length direction, and the light strip 25 can emit light to the light guide component 23 from multiple positions on the edge of the light guide component 23, making the light in the light guide component 23 more uniform; the heat sink 22 can accelerate the heat dissipation of the light strip 25, so that the light strip 25 can work stably.

[0079] In some embodiments, please refer to Figure 5 and Figure 10 The light guide assembly 23 includes a reflective sheet 231, a light guide plate 232, and a film 233 stacked along the thickness direction Y of the support plate 11. A light strip 25 is disposed below the light guide plate 232. Light from the light strip 25 enters the light guide plate 232 and diffuses evenly within it. The reflective sheet 231 reflects light emitted from the light guide plate 232 back to the light guide plate 232, ensuring full utilization of the light. The film 233 diffuses the light evenly, improves the overall brightness of the display panel 24, and increases the brightness of the center of the display panel 24.

[0080] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 11 The display module 20 also includes a middle frame 27 connected to the back plate 21. The middle frame 27 includes a second frame 272 connected to the back plate 21 and a plurality of limiting plates 271. The second frame 272 is fitted onto the back plate 21. The limiting plates 271 are connected to one end of the second frame 272 along the thickness direction Y of the support plate 11 near the display panel 24. The limiting plates 271 are located on the side of the light guide assembly 23 away from the back plate 21, and the limiting plates 271 hold the light guide assembly 23 against the back plate 21. The display panel 24 is connected to the side of the plurality of limiting plates 271 away from the light guide assembly 23.

[0081] In the thickness direction Y of the support plate 11, the second frame 272 extends from the back plate 21 toward the direction close to the display panel 24.

[0082] Along the thickness direction Y of the support plate 11, the light guide assembly 23 is located between the limiting plate 271 and the back plate 21, with the limiting plate 271 and the back plate 21 clamping and fixing the light guide assembly 23. The limiting plate 271 is fixed to the back plate 21 by the second frame 272. The thickness direction of the limiting plate 271 is consistent with the thickness direction of the display panel 24. Optionally, the display panel 24 can be attached to the limiting plate 271 using foam double-sided adhesive 80.

[0083] For example, please refer to Figure 5 and Figure 11 There are four limiting plates 271. The second frame 272 is a rectangular ring. Two limiting plates 271 are connected to the two ends of the second frame 272 along the length direction X of the support plate 11, and the other two limiting plates 271 are connected to the two ends of the second frame 272 along the height direction Z of the support plate 11.

[0084] The beneficial effects of this embodiment are as follows: the second frame 272 of the middle frame 27 is sleeved on the back plate 21 and can be stably connected to the back plate 21; the limiting plate 271 and the back plate 21 can clamp and fix the light guide assembly 23; the second frame 272 can limit the position of the light guide assembly 23 in the thickness direction Y of the vertical support plate 11, so that the light guide assembly 23 remains stable. Moreover, the limiting plate 271 can support the display panel 24, so that the display panel 24 remains stable.

[0085] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 12 Each edge of the back plate 21 is bent away from the support plate 11 to form a bent portion 211. The main body 212 of the back plate 21 is located between the multiple bent portions 211. The multiple bent portions 211, the main body 212, and the limiting plate 271 form an accommodating space, within which the light guide assembly 23 and the light strip 25 are located. The second frame 272 is fitted onto the multiple bent portions 211 and is snapped and fixed to the bent portions 211.

[0086] In some embodiments, please refer to Figure 4 and Figure 6 The rear panel 40 has a first through hole 42; a portion of the support plate 11 is recessed away from the rear panel 40 to form a third mounting groove 114; the display device 100 also includes a bracket 50 connected to the support plate 11, which passes through the first through hole 42 and is disposed in the third mounting groove 114. On the surface of the support plate 11 along its thickness direction Y, the orthographic projection of the third mounting groove 114 is offset from the orthographic projection of the main board 30.

[0087] The first through hole 42 extends through the rear panel 40 along the thickness direction Y of the support plate 11.

[0088] The support plate 11 is recessed along its thickness direction Y to the side away from the rear panel 40, forming a third mounting groove 114, which is positioned opposite the first through hole 42. Optionally, the third mounting groove 114 is located at the center of the support plate 11, and the bracket 50 is connected to the center of the support plate 11 to stably support the rear shell 10. Optionally, the bracket 50 is a lifting bracket.

[0089] On the side of the support plate 11 facing away from the rear panel 40 along its thickness direction Y, there is space to accommodate the motherboard 30. On the surface of the support plate 11 along its thickness direction Y, the orthographic projection of the third mounting groove 114 is completely offset from the orthographic projection of the motherboard 30. Thus, the space for accommodating the motherboard 30 is utilized by the support plate 11, which is recessed away from the rear panel 40. The bracket 50 passes through the first through hole 42 and is disposed in the third mounting groove 114. Therefore, in the thickness direction Y of the support plate 11, the sum of the dimensions of the bracket 50, the rear panel 40, the support plate 11, and the motherboard 30 is less than the sum of the dimensions of the bracket 50, the support plate 11, and the motherboard 30, making the display device 100 thinner. Moreover, the third mounting groove 114 can position the bracket 50, resulting in higher installation efficiency for the bracket 50.

[0090] In some embodiments, please refer to Figure 4 and Figure 6 The support plate 11 is provided with a first receiving hole 112, and some components of the main board 30 are located in the first receiving hole 112. In the thickness direction Y of the support plate 11, the overall size of the support plate 11 and the main board 30 is smaller than the sum of the size of the support plate 11 and the size of the main board 30, so the display device 100 is relatively thin.

[0091] In some embodiments, the rear panel 40 is made of tempered glass, which is adhered to the support plate. Tempered glass has high strength and makes the back of the display device 100 more aesthetically pleasing. Optionally, the tempered glass can be adhered to the support plate 11 using foam double-sided adhesive 80, ensuring a stable connection between the tempered glass and the support plate 11, while the foam provides cushioning and protection. Optionally, the tempered glass can also be adhered to the support plate 11 using glue.

[0092] In other embodiments, the rear panel 40 may also be a metal plate or a plastic plate, etc.

[0093] In some embodiments, please refer to Figure 4 and Figure 6 The support plate 11 is also provided with a second receiving hole 113; the display device 100 also includes a lamp plate 70 connected to the support plate 11, the lamp plate 70 is disposed in the second receiving hole 113, and the lamp plate 70 is used to emit light toward the rear panel 40.

[0094] The second receiving hole 113 penetrates the support plate 11 along its thickness direction Y. The thickness direction of the lamp plate 70 is the same as or substantially the same as the thickness direction Y of the support plate 11. Since the lamp plate 70 is disposed in the second receiving hole 113, the sum of the dimensions of the lamp plate 70 and the support plate 11 along the thickness direction Y is less than the sum of the dimensions of the lamp plate 70 and the support plate 11, resulting in a thinner display device 100. The second receiving hole 113 is completely offset from the third mounting groove 114. Optionally, the orthographic projection of the lamp plate 70 and the orthographic projection of the main board 30 are completely offset on the surface of the support plate 11 along its thickness direction Y. Optionally, the multiple light sources on the lamp plate 70 are arranged in a dot matrix. Optionally, a pattern with the same shape as the lamp plate 70 can be provided on the rear panel 40.

[0095] The beneficial effects of this embodiment are as follows: the light panel 70 emits light towards the rear panel 40, which can illuminate the back of the display device 100, making it convenient to insert wires on the back of the display device 100, and the back of the display device 100 is more aesthetically pleasing when the light panel 70 is emitting light. Since the light panel 70 is disposed in the second receiving hole 113, the overall thickness of the light panel 70 and the support plate 11 is smaller, resulting in a thinner display device 100.

[0096] In some embodiments, please refer to Figure 4 and Figure 6 The support plate 11 around the second receiving hole 113 is recessed to the side away from the rear panel 40 and forms a mounting part 115. The lamp plate 70 is fixed on the mounting part 115 and the lamp plate 70 is located between the mounting part 115 and the rear panel 40.

[0097] In some embodiments, please refer to Figures 1 to 9 The display device 100 includes a rear shell 10, a rear panel 40, a main board 30, and a display module 20. The rear shell 10 includes a first frame 12 and a support plate 11 disposed within the first frame 12. The first frame 12 and the support plate 11 form a first groove 13 along their respective thickness direction Y. The display module 20 is connected to the support plate 11 and is completely located within the first groove 13. The display module 20 includes a display panel 24. The first frame 12 and the support plate 11 form a second groove 14 along their respective thickness direction Y away from the rear panel 40. The rear panel 40 is completely located within the second groove 14. The rear panel 40 is connected to the support plate 11 on the side away from the display module 20, and the side of the rear panel 40 away from the support plate 11 is flat.

[0098] The display module 20 also includes a back plate 21, a heat sink 22, and a light guide assembly 23 arranged sequentially on the side of the motherboard 30 near the display panel 24; the back plate 21 is fixed to the support plate 11, and the motherboard 30 and the heat sink 22 are respectively connected to the two sides of the back plate 21; a portion of the back plate 21 is recessed towards the light guide assembly 23 and forms a first mounting groove 213, and the motherboard 30 is located in the first mounting groove 213; a portion of the back plate 21 is recessed towards the support plate 11 and forms a second mounting groove 214, and the heat sink 22 is located in the second mounting groove 214.
