[0073] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0074] like Figures 1 to 5 As shown, according to an embodiment of the first aspect of this application, a display module is provided, including a bracket 110. Specifically, the bracket 110 is formed with a first portion c, a second portion d, and a third portion e. The first portion c of the bracket 110 is higher than the second portion d, the second portion d is higher than the third portion e, and the first portion c is connected to the second portion d, while the second portion d is connected to the third portion e. A protrusion 111 is formed on the periphery of the first part c of the bracket 110, and the end of the protrusion 111 away from the first part c of the bracket 110 tapers towards the end of the protrusion 111 closer to the bracket 110; a cover plate 120 is provided on the first part c of the bracket 110, and a placement space a is formed between the cover plate 120 and the third part e of the bracket 110; a display component 130 is disposed in the placement space a; a touch board is connected to the second part d of the bracket 110; a protective sleeve 140 is sleeved on the first part c of the bracket 110, and the protective sleeve 140 has a groove that fits with the protrusion 111, and the periphery of the cover plate 120 abuts against the protective sleeve 140.

[0075] It is understood that the display module provided in this application embodiment includes a bracket 110, a cover plate 120, a display component 130, and a protective sleeve 140. A placement space a is formed between the bracket 110 and the cover plate 120, within which the display component 130 can be placed. The cover plate 120 has a transparent area corresponding to the placement space a, allowing the content displayed by the display component 130 to be observed from outside the cover plate 120. A protrusion 111 is formed on the periphery of the bracket 110 in the thickness direction, with the end of the protrusion 111 away from the bracket 110 converging towards the end closer to the bracket 110. Simultaneously, a groove is formed on the side of the protective sleeve 140 near the bracket 110, with the groove and protrusion 111 corresponding in position and shape. This allows the groove and protrusion 111 to fit together, and after fitting, they are in a self-locking state, improving the connection and tightness between the protective sleeve 140 and the bracket 110.

[0076] For example, such as Figure 6 and Figure 7 As shown, multiple protrusions 111 can be provided, and the number of grooves corresponds to the number of protrusions 111. By providing multiple protrusions 111 and multiple grooves, the connection and tightness between the protective sleeve 140 and the bracket 110 can be further improved. The groove can be a dovetail groove 141, and the shape of the protrusion 111 matches the dovetail groove. The dovetail dimension of the dovetail groove 141 is between 1mm and 1.8mm in depth, for example, 1.2mm. The side length of the dovetail groove 141 near the bracket is between 16mm and 22mm, and the side length of the dovetail groove 141 away from the bracket is between 18mm and 24mm. At the corner, the arc length of the dovetail groove 141 near the bracket is between 14mm and 18mm, and the side length of the dovetail groove 141 away from the bracket is between 15mm and 20mm. The chamfer is 30° to 60°, for example, 42°.

[0077] The shape of the bracket 110 can be determined according to the shape of the display component 130. For example, the display component 130 and the bracket 110 can be rectangular, and the four corners of the rectangular bracket 110 can be rounded to improve the appearance and reduce damage from bumps and knocks. In addition, the line of the end of the protrusion 111 away from the bracket 110 can be consistent with the outer line of the bracket 110 to improve the appearance.

[0078] Understandably, the height of the end of the protective sleeve 140 furthest from the display component 130 is greater than the height of the bracket 110, so that the periphery of the cover plate 120 abuts against the protective sleeve 140. This arrangement serves several purposes: firstly, the protective sleeve 140 can absorb impact forces on the cover plate 120 and the bracket 110, improving their protective performance; secondly, the protective sleeve 140 prevents foreign matter such as smoke and moisture from entering the display component 130 through the cover plate 120 in harsh working environments, ensuring the display component 130 remains in a stable working state and improving reliability; and thirdly, the protective sleeve 140 restricts the relative position of the cover plate 120 and the bracket 110, ensuring the stability of their connection.

[0079] It is understood that the bracket 110 can be mounted on the display device, and the outer side of the protective sleeve 140 abuts against the display device. For example, the display device is a kitchen appliance, such as a smart cooking machine, air fryer, or rice cooker. In the application environment of such appliances, the display module experiences significant amounts of oil fumes and moisture. By providing the protective sleeve 140, oil fumes and moisture can be effectively prevented from entering the display component 130, thus improving the protection of the display component 130.

[0080] For example, the cover plate 120 can be made of glass, and its edges have a 3D curved structure to form a curved screen, improving its aesthetic appeal. Meanwhile, the edge shape of the protective sleeve 140 can follow that of the cover plate 120. The edges of the protective sleeve 140 also have a 3D curved structure, and both have the same arc angle, further enhancing the aesthetics and making the cover plate 120 and protective sleeve 140 more compatible, improving assembly reliability.

[0081] In some examples, the bracket 110 and the protective sleeve 140 are made using a two-color injection molding process, and the protective sleeve 140 is made of silicone.

[0082] Understandably, the bracket 110 can be made of a harder material to improve the protection of the display component 130, while the protective sleeve 140 can be made of a softer material to better fit the connection between the cover plate 120 and the display device, preventing oil fumes and moisture from entering the display component 130, and better absorbing the impact force on the cover plate 120 and the display component 130, thus improving the protection of the display component 130. Therefore, the bracket 110 and the protective sleeve 140 can be manufactured using a two-color injection molding process. After the two-color injection mold is prepared, the material for the bracket 110 is injected into the corresponding position of the bracket 110 in the mold using an injection molding machine, and the material for the protective sleeve 140 is injected into the corresponding position of the protective sleeve 140 in the mold, thereby achieving two-color molding.

[0083] For example, the support 110 can be made of ABS (Acrylonitrile Butadiene Styrene copolymer) to give it high strength and toughness, and make it easy to process and mold. Alternatively, the support 110 can be made of ABS and PC (Polycarbonate) to improve its mechanical properties. The protective sleeve 140 can be made of silicone, which has a long service life, and silicone has stable chemical properties and is suitable for a wide range of applications.

[0084] In some examples, such as Figure 1 and Figure 2 As shown, the above-mentioned display module also includes a waterproof layer 121, which is disposed between the bracket 110 and the cover plate 120.

[0085] It is understandable that a waterproof layer 121 can be provided between the first part c of the bracket 110 and the cover plate 120 to further improve the waterproof capability of the display module. This allows the display module to adapt to usage scenarios with high moisture content, improving reliability. For example, the display device is a kitchen appliance, such as a smart cooking machine, air fryer, or rice cooker. Moisture generated during the operation of the kitchen appliance will be blocked by the protective sleeve 140 and the waterproof layer 121, preventing it from entering the display component 130 and ensuring that the display component 130 can still display normally in this usage scenario, thus improving stability.

[0086] For example, the waterproof layer 121 may be made of a waterproof adhesive, such as 5520PSB or 5525PSB waterproof adhesive.

[0087] In some examples, such as Figure 9 As shown, the display component 130 includes: a first polarizer 131 disposed close to the cover plate 120; a second polarizer 132 disposed away from the cover plate 120; a display panel 133 disposed between the first polarizer 131 and the second polarizer 132; and a backlight 134 disposed on the side of the second polarizer 132 away from the display panel 133.

[0088] It is understood that the display assembly 130 includes a first polarizer 131, a second polarizer 132, a display panel 133, and a backlight 134. Specifically, the display panel 133 includes a color filter, a liquid crystal layer, and a thin-film transistor (TFT) glass. A conductive film can be formed on the TFT glass using sputtering and chemical deposition processes. Various large-scale circuits can be fabricated using this conductive film, significantly reducing costs. Each liquid crystal pixel in the display assembly 130 is driven by a TFT, enabling high-speed, high-brightness, and high-contrast display of screen information. The color filter is located on the side of the TFT glass closest to the cover plate 120. The color filter has multiple primary color units arranged in an array. By adjusting the intensity of light passing through the color units, the color units can display the desired color. The liquid crystal layer is located between the color filter and the TFT glass. The first polarizer 131 is located on the side of the color filter closest to the cover plate 120, and the backlight 134 is located on the side of the TFT glass furthest from the cover plate 120. Furthermore, a second polarizer 132 is disposed between the backlight 134 and the thin-film transistor glass. Under the influence of an electric field, the liquid crystal molecules undergo a change in alignment, thereby affecting the intensity of the incident light beam passing through the liquid crystal. Accordingly, by controlling the electric field of the liquid crystal and the filtering effect of the first polarizer 131 and the second polarizer 132, changes in the brightness of the light can be achieved, and through the action of the color filter, the display component 130 can achieve the purpose of displaying different color information.

[0089] In some examples, such as Figure 9 As shown, the backlight 134 includes: a film material; a plurality of reflective sheets 1341, the plurality of reflective sheets 1341 surrounding a reflective groove, the reflective groove forming a first opening and a second opening, wherein the first opening is disposed on the side where the film material is located, and the second opening is disposed on the side where the light source of the backlight is located; a light guide plate 1342, disposed in the reflective groove, and a portion of the light guide plate 1342 extends out of the first opening, and the light source is disposed on the side of the light guide plate 1342 corresponding to the second opening.

[0090] Understandably, the backlight 134 includes a film material, multiple reflectors, and a light guide plate 1342. The multiple reflectors 1341 can be arranged to form a reflective groove. Specifically, the reflective groove can be formed by four reflectors 1341, with one reflector 1341 serving as the bottom of the groove and the other three as the sidewalls, creating a first opening and a second opening. The first opening is formed at the top of the groove, facing the film material, while the second opening is formed on the side of the groove, facing the light source. The light guide plate 1342 is placed within the reflective groove, with corresponding reflectors 1341 on each of its three sides. The light source corresponds to the side of the light guide plate 1342 at the second opening, allowing light emitted from the light source to illuminate the light guide plate 1342. This configuration allows light emitted from the light source located on the side of the light guide plate 1342 to be converted into a concentrated surface light source that illuminates the film material. Furthermore, the light emitted from the other three sides of the light guide plate 1342 is reflected back to the light guide plate 1342 by the reflective plates in multiple directions, enabling the reflected light to be reused, reducing light loss, improving light utilization, and increasing light intensity. For example, the light guide plate 1342 can be made of PC with a thickness of 1.8mm.

[0091] Understandably, the membrane material is equipped with a diffuser 1347, a first prism 1348, and a second prism 1349. The first prism 1348 is located near the light guide plate 1342 on the side of the first opening, the second prism 1349 is located on the side of the first prism 1348 away from the light guide plate 1342, and the diffuser 1347 is located on the side of the second prism 1349 away from the first prism 1348. The first prism 1348 and the second prism 1349 concentrate the light emitted from the light guide plate 1342, thereby increasing the light brightness. Furthermore, the diffuser 1347 broadens the field of view and makes the light relatively balanced across the entire plane, improving the uniformity of the light after passing through the first prism 1348 and the second prism 1349.

[0092] In some examples, such as Figure 9 and Figure 10 As shown, the backlight 134 further includes: a frame 1343, with a support position formed on the inner side of the frame 1343, and the side of the second polarizer 132 facing away from the display panel 133 abutting against one side of the support position; a back plate 1344, with the side of the reflective groove facing away from the opening connected to the back plate 1344, and the back plate 1344 having a bent section abutting against the other side of the support position; and an edge-sealing tape 1345 bonded to the bottom of the back plate 1344 and the outer wall of the frame 1343.

[0093] Understandably, the backlight 134 also includes a frame 1343, a backplate 1344, and edge-sealing tape 1345. The first polarizer 131, the second polarizer 132, and the display panel 133 are disposed within the frame 1343, and a protrusion is formed on the inner side of the frame 1343 as a support. Specifically, the second polarizer 132 abuts against the protrusion, thereby determining its position within the frame 1343. The backplate 1344 has a bent section, with the bending direction facing the frame 1343. The backplate 1344 abuts against the side of the protrusion away from the second polarizer 132 via the bent section, thus determining the relative position of the backplate 1344 and the frame 1343. The side of the reflector groove facing away from the opening can be glued to the backplate 1344 to fix the backlight 134 to the backplate 1344, ensuring that the light passing through the backlight 134 can illuminate the second polarizer. One end of the edge-sealing tape 1345 is adhered to the side of the back panel 1344 facing away from the bottom of the reflector groove, and the other end of the edge-sealing tape 1345 is adhered to the top of the frame 1343 and the display panel 133. The edge-sealing tape 1345 wraps around the outside of the frame 1343, fixing the relative positions of the back panel 1344 and the frame 1343, as well as the relative positions of the frame 1343 and the display panel 133. This improves the tightness and stability of the connection.

[0094] It is understandable that black double-sided adhesive is provided between the support position of the second polarizer 132 and the frame 1343 to make the second polarizer 132 and the frame 1343 stick together, so as to make the second polarizer 132 and the frame 1343 firmly connected and improve reliability.

[0095] For example, the frame 1343 can be made of plastic, and the back plate 1344 can be made of AL5052 material to ensure that the back plate 1344 has good heat dissipation and that the display module 130 has stable working performance. The thickness is 0.3 mm, and the thickness of the edge-sealing tape 1345 is 0.06 mm, which can effectively reduce the overall thickness of the display module 130 and facilitate the improvement of the overall structural layout of the display module.

[0096] In some examples, such as Figure 9 As shown, the display module further includes: a touch substrate 150; a placement groove 112 is formed on the side of the bracket 110 near the cover plate 120, and the display component 130 is placed in the placement groove 112; a first cutout 1121 is provided at the connection between the side wall and the bottom of the placement groove 112, and a second cutout 1122 is provided at the bottom of the placement groove 112, wherein the first flexible circuit board 151 of the touch substrate 150 passes through the first cutout 1121, and the second flexible circuit board 1331 of the display panel 133 passes through the second cutout 1122.

[0097] Understandably, the display module also includes a touch substrate 150. Specifically, the touch substrate 150 is located between the cover plate 120 and the first polarizer 131. Users can view the display information of the display component 130 through the cover plate 120 and adjust the display information by touching the cover plate 120. This makes operation more convenient and improves the user experience. A placement groove 112 is formed on the side of the bracket 110 near the cover plate 120 to provide installation space for the display component 130. A first cutout 1121 and a second cutout 1122 can be formed at the bottom of the placement groove 112. The first flexible circuit board 151 of the touch substrate 150 can pass through the first cutout 1121 and connect to the control motherboard 160, and the second flexible circuit board 1331 of the display panel 133 can pass through the second cutout 1122 and connect to the control motherboard 160. This avoids excessive wiring exposed on the side of the bracket 110, making the wiring more reasonable.

[0098] It is understood that the location, shape, and size of the placement slot 112 can be determined according to specific product requirements. For example, such as... Figure 7 As shown, the area of ​​the placement groove 112 is i, and the area of ​​area i occupies 2 / 3 to 4 / 5 of the area of ​​the side of the bracket 110 where the placement groove 112 is located. The area of ​​the first cutout 1121 occupies 3 / 500 to 1 / 50 of the area of ​​the placement groove 112, and the area of ​​the second cutout 1122 occupies 2 / 50 to 8 / 50 of the area of ​​the placement groove 112.

[0099] For example, the touch substrate 150 may be made of capacitive touch glass, and OCA (Optically Clear Adhesive) is applied between the capacitive touch glass and the display component 130 to fix the capacitive touch glass to the display component 130. It has the characteristics of high clarity, high light transmittance, high adhesion, high weather resistance, water resistance, high temperature resistance, and UV resistance, and will not cause yellowing, peeling, or deterioration problems after long-term use.

[0100] In some examples, such as Figure 5 As shown, a clearance pit 1123 is formed in the placement groove 112 to accommodate the components of the display panel 133.

[0101] It is understood that a clearance recess 1123 can be formed within the placement slot 112 of the bracket 110, thereby creating a space to accommodate the components of the display panel 133. Some components of the display panel 133 will protrude from the display panel 133. When the display component 130 is installed in the placement slot 112, these components can be placed in the clearance recess 1123, thereby making the connection between the display component 130 and the bracket 110 more stable and arranging the installation space more reasonably. The size and position of the clearance recess 1123 can be determined according to the size and position of the components protruding from the surface of the display panel 133, improving adaptability.

[0102] For example, the components of the display panel 133 are ICs (Integrated Circuit Chips).

[0103] In some examples, such as Figure 5 and Figure 8 As shown, the above-mentioned display module also includes: a control motherboard 160, a mounting position 113 is formed on the side of the bracket 110 away from the cover plate 120, the control motherboard 160 is placed in the mounting position 113, and the first flexible circuit board 151 and the second flexible circuit board 1331 are respectively electrically connected to the control motherboard 160.

[0104] Understandably, the display module also includes a control motherboard 160. Specifically, a mounting position 113 can be formed on the side of the bracket 110 opposite to the display component 130. The control motherboard 160 can be placed in the mounting position 113, and the first flexible circuit board 151 can pass through the first cutout 1121 and be located in the mounting position 113, connected to the control motherboard 160. The second flexible circuit board 1331 can pass through the second cutout 1122 and be located in the mounting position 113, connected to the control motherboard 160. This layout reduces the overall thickness of the display module and the length of exposed lines. The user can observe the parameters displayed by the display component 130 through the cover plate 120 and the touch board 150. By touching the cover plate 120, the user can operate the touch board 150. The touch board 150 can send the user's adjustment information to the control motherboard 160. While the user adjusts the parameters through the control motherboard 160, the control motherboard 160 can control the display component 130 to display the adjusted parameters to provide feedback to the user.

[0105] For example, the display device is a smart cooking machine. The display component 130 can display various operating parameters of the smart cooking machine, such as the stir-frying time. The user can touch the cover plate 120 to operate the touch board 150 to adjust the stir-frying time. The touch board 150 can send the stir-frying time information adjusted by the user to the control motherboard 160. The control motherboard 160 can adjust the stir-frying time of the smart cooking machine. At the same time, the control motherboard 160 can control the display component 130 to display the adjusted stir-frying time, so that the user can more intuitively understand the adjusted stir-frying time and improve the user experience.

[0106] In some examples, such as Figures 9 to 11 As shown, the display module further includes: a limiting member disposed at the mounting position 113 for limiting the relative position of the control motherboard 160 and the bracket 110; and a fixing member for fixing the control motherboard 160 to the bracket 110.

[0107] Understandably, the display module also includes limiting and fixing components. Specifically, a limiting component is provided at the mounting position 113 to restrict the position of the control motherboard 160 within the mounting position 113. Simultaneously, the fixing component secures the control motherboard 160 to the mounting position 113, ensuring its position relative to the bracket 110 remains fixed. This ensures stable connection between the control motherboard 160 and the first flexible circuit board 151 and the second flexible circuit board 1331, guaranteeing stable operation of the display module and improving reliability.

[0108] In some examples, such as Figures 9 to 11 As shown, the limiting member is a stop block 170, the stop block 170 has a slot 171, one end of the control motherboard 160 is engaged in the slot 171; and / or, the fixing member is a bolt 180, the mounting position 113 has a threaded hole, the bolt 180 passes through the other end of the control motherboard 160 and is screwed into the threaded hole.

[0109] Understandably, the limiting component can be a stop block 170, and two stops 170 can be provided. Two corners on the same side of the control motherboard 160 can each abut against one stop block 170, thereby restricting the movement of the control motherboard 160 along the length of the bracket 110. After the stop block 170 limits the position of the control motherboard 160, the control motherboard 160 is fixed by a fixing component. Specifically, a through hole can be provided at the end of the control motherboard 160 away from the stop block 170, and a threaded hole can be provided at the mounting position 113. When the control motherboard 160 abuts against the stop block 170, the through hole corresponds to the threaded hole. The stop block 170 is provided to facilitate the positioning of the control motherboard 160 and to facilitate quick fixing of the control motherboard 160 using a fixing component, thus improving assembly efficiency. The fixing component can be a bolt 180, which passes through the through hole and is screwed into the threaded hole to fix the control motherboard 160 to the bracket 110. This ensures a stable connection between the control motherboard 160, the first flexible circuit board 151, and the second flexible circuit board 1331, thereby ensuring stable operation of the display module and improving reliability.

[0110] It is understood that the stop block 170 can be a hexahedral hollow structure, and the bottom of the stop block 170 is connected to the bracket 110. Furthermore, the bottom of the stop block 170 and the corresponding position on the bracket have production holes 172, which connect to the hollow part inside the stop block 170 to facilitate mold opening of the bracket 110 and facilitate the production of the bracket 110. The stop block 170 faces the control motherboard 160, with the side closer to the control motherboard 160 being the first side, and the side adjacent to the first side and closer to the control motherboard 160 being the second side. The first side has a first opening, and a first retaining wall 173 is provided on the side of the first opening near the bracket; the second side has a second opening, and a second retaining wall 174 is provided on the side of the second opening away from the first side. The first and second openings together form a slot 171, and the corners of the control motherboard 160 can be engaged in the slot 171, thereby improving the limiting ability of the stop block 170 on the control motherboard 160.

[0111] For example, the width of the first opening ranges from 3mm to 4mm, the width of the second opening ranges from 5mm to 6.5mm, the height of the first retaining wall 173 ranges from 2mm to 3mm, the width of the second retaining wall 174 ranges from 2.2mm to 3mm, the height of the block ranges from 3mm to 3.5mm, and the width of the block ranges from 1.2mm to 1.8mm.

[0112] In some examples, such as Figure 9 As shown, the above-mentioned display module also includes: a mounting member 190, which is disposed on the side of the bracket 110 away from the cover plate 120, for mounting the bracket 110 to the opponent member.

[0113] Understandably, the display module is also provided with a mounting component 190. Specifically, the mounting component 190 is located on the side of the bracket 110 opposite to the display assembly 130. The display module can be mounted on the counterpart component through the mounting component 190 to form a display device, ensuring a tight connection between the display module and the counterpart component and improving reliability.

[0114] In some examples, such as Figure 8 As shown, the mounting component 190 includes: a mounting post 191, which has an internal thread for threaded connection with the aforementioned opponent component; and a snap fastener 192 for snapping into the aforementioned opponent component.

[0115] Understandably, the mounting component 190 may be provided with a mounting post 191, which protrudes from the bracket 110 on the side opposite to the display component 130. The mounting post 191 has an internal thread, and correspondingly, a mounting hole is provided on the opposing component. When the display component 130 is mounted on the opposing component, the mounting post 191 passes through the mounting hole and is screwed onto the internal thread by a bolt 180. Furthermore, the mounting component 190 is also provided with a latch 192, forming a locking position on the opposing component. The latch 192 can engage with the locking position. Through these two connection methods, the display module is mounted on the opposing component, improving the connection tightness and reliability.

[0116] For example, four mounting posts 191 are provided, located at the four corners of the bracket 110. Four fasteners are provided, symmetrically arranged in the middle of the bracket 110, thereby ensuring that the display module and the connecting parts are subjected to uniform force and improving stability.

[0117] In some examples, such as Figure 3 and Figure 4 As shown, the above-mentioned display module also includes: a knob 200, electrically connected to the control motherboard 160; a fixing sleeve 114, disposed on the bracket 110; the cover plate 120 has a first through hole; the non-display area of ​​the touch substrate 150 has a second through hole; the fixing sleeve 114 passes through the first through hole and the second through hole; and the knob 200 passes through the fixing sleeve 114.

[0118] Understandably, the display module also includes a knob 200, which is electrically connected to the control motherboard 160. Specifically, a fixing sleeve 114 is provided on the side of the bracket 110 facing the display component 130, and a first through hole is provided in the corresponding area of ​​the cover plate 120. A second through hole is provided in the non-display area of ​​the touch board 150. The fixing sleeve 114 can pass through the second through hole and the first through hole in sequence and is located on the top of the cover plate 120. The knob 200 can be inserted into the fixing sleeve 114, which restricts the circumferential displacement of the knob 200 and restricts the knob 200 to rotate only around its own axis. Users can adjust the parameters of the display device by rotating the knob 200, and the display component 130 displays the adjusted parameters, making the operation simple and improving the user experience.

[0119] For example, the display device is a smart cooking machine. The cooking temperature can be adjusted by turning the knob 200, and the user can observe the current cooking temperature and heat level displayed on the display component 130 through the cover 120. After the user adjusts the cooking temperature by turning the knob 200, the control motherboard 160 controls the smart cooking machine to adjust the power to change the cooking temperature to the user-adjusted temperature. At the same time, the control motherboard 160 controls the display component 130 to display the adjusted cooking temperature and heat level.

[0120] like Figure 8 As shown, by way of example, the area j where the bracket 110 is provided with the fixing sleeve 114 is denoted as j, and the area k where the bracket 110 is used to place the components of the display panel 133 is denoted as k. On the projection in the horizontal direction, the areas of j and k are approximately equal, and the ratio of the area of ​​the bracket 110 located in area j or area k to the area between area j and area k can be in the range of 3 / 19 to 3 / 16.

[0121] In some examples, such as Figure 14 As shown, the above-mentioned display module also includes: multiple interfaces 161, which are disposed on the control motherboard 160; a shielding cover 162, which covers the components of the control motherboard 160; and a base plate 210, which is connected to the bracket 110 and covers the side of the control motherboard 160 away from the bracket 110.

[0122] Understandably, the display module also has multiple interfaces 161, and the control motherboard 160 can integrate multiple control modules to control various functions of the display device. The functional units of the display device can be electrically connected to the corresponding control modules of the control motherboard 160 through the interfaces 161. For example, the interfaces 161 include a knob 200 interface 161, a touch interface 161, a display component 130 interface 161, a communication interface 161, a power interface 161, and a speaker interface 161. A base plate 210 can be provided on the side of the control motherboard 160 away from the bracket 110. The base plate 210 covers the control motherboard 160, providing shielding and protection, thereby extending the service life of the control motherboard 160.

[0123] Understandably, the display module is also equipped with a shielding cover 162. The control module on the control motherboard 160 is equipped with corresponding components, and the shielding cover 162 can cover the components of the control motherboard 160 to ensure that components with different functions do not interfere with each other and improve operational stability.
