[0073] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to 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 the present 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 of the bracket 110, the second portion d of the bracket 110 is higher than the third portion e of the bracket 110, and the first portion c of the bracket 110 is connected to the second portion d of the bracket 110, and the second portion d of the bracket 110 is connected to the third portion e of the bracket 110. A protrusion 111 is formed on the peripheral side 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 shrinks toward the end of the protrusion 111 close to the bracket 110; the cover plate 120 is covered 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; the display component 130 is arranged in the placement space a; the touch substrate is connected to the second part d of the bracket 110, and the protective cover 140 is sleeved on the first part c of the bracket 110, and the protective cover 140 is formed with a groove body, the groove body and the protrusion 111 are matched, and the peripheral side of the cover plate 120 abuts against the protective cover 140.

[0075] It can be understood that the display module provided in the embodiment of the present application is provided with a bracket 110, a cover plate 120, a display assembly 130 and a protective cover 140. Among them, a placement space a is formed between the bracket 110 and the cover plate 120, and the display assembly 130 can be placed in the placement space a. The cover plate 120 is formed with a transparent area, and the transparent area corresponds to the placement space a, so that the content displayed by the display assembly 130 can be observed from the outside of the cover plate 120. And a protrusion 111 is formed on the peripheral side of the thickness direction of the bracket 110, and the end of the protrusion 111 away from the bracket 110 shrinks toward the end of the protrusion 111 close to the bracket 110. At the same time, a groove body can be formed on one side of the protective cover 140 close to the bracket 110, and the positions of the groove body and the protrusion 111 correspond and the shapes match. So that the groove body and the protrusion 111 can fit each other, and the groove body and the protrusion 111 can be in a self-locking state after fitting, thereby improving the connection tightness of the protective cover 140 and the bracket 110.

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

[0077] The shape of the bracket 110 can be determined according to the shape of the display assembly 130. For example, the display assembly 130 and the bracket 110 can be rectangular in shape, and the four corners of the rectangular bracket 110 can be rounded to improve the appearance and reduce the damage caused by the edges. In addition, the linear shape of the end of the protrusion 111 away from the bracket 110 can be consistent with the outer linear shape of the bracket 110 to improve the appearance.

[0078] It is understandable that the height of the end of the protective sleeve 140 away from the display assembly 130 is greater than the height of the bracket 110, so that the peripheral side of the cover plate 120 abuts against the protective sleeve 140. With such a configuration, on the one hand, the protective sleeve 140 can absorb the impact force on the cover plate 120 and the bracket 110, thereby improving the protection performance of the cover plate 120 and the bracket 110; on the other hand, by providing the protective sleeve 140, foreign matter such as smoke, water vapor, etc. can be prevented from entering the display assembly 130 from the cover plate 120 in a relatively harsh working environment of the display module, thereby ensuring that the display assembly 130 is always in a stable working state and improving reliability; on the other hand, the protective sleeve 140 can limit the relative position of the cover plate 120 and the bracket 110, thereby ensuring the stability of the connection between the cover plate 120 and the bracket 110.

[0079] It is understandable that the bracket 110 can be installed on the display device, and the outer side of the protective cover 140 abuts against the display device. Exemplarily, the display device is a kitchen appliance, such as an intelligent cooking machine, an air fryer, and an electric rice cooker. In the application environment of the display module in such appliances, there is a lot of oil smoke and water vapor. By setting the protective cover 140, the oil smoke and water vapor can be effectively prevented from entering the display assembly 130, thereby improving the protection of the display assembly 130.

[0080] For example, the cover plate 120 can be made of glass, and the edge of the cover plate 120 is a 3D arc structure, forming a curved screen, which improves the appearance. At the same time, the edge shape of the protective cover 140 can follow the edge shape of the cover plate 120. The edge of the protective cover 140 is also a 3D arc structure, and the arc angles of the two are the same, which further improves the appearance, makes the cover plate 120 and the protective cover 140 more adaptable, and improves the assembly reliability.

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

[0082] It is understandable that the bracket 110 can be made of a harder material to improve the protection of the display component 130, and the protective cover 140 can be made of a softer material to better fit the connection between the cover plate 120 and the display device, prevent oil smoke and water vapor from entering the display component 130, and better absorb the impact force on the cover plate 120 and the display component 130, thereby improving the protection of the display component 130. Therefore, the bracket 110 and the protective cover 140 can be made using a two-color injection molding process. After the two-color injection mold is prepared, the prepared material of the bracket 110 is injected into the corresponding position of the bracket 110 of the mold through an injection molding machine, and the prepared material of the protective cover 140 is injected into the corresponding position of the protective cover 140 of the mold, thereby achieving two-color molding.

[0083] For example, the material of the bracket 110 can be ABS (Acrylonitrile Butadiene Styrene) so that the bracket 110 has high strength and toughness and is easy to process. Alternatively, the material of the bracket 110 can be ABS and PC (Polycarbonate) to improve the mechanical properties of the bracket 110. The protective cover 140 can be made of silicone material, which has a long service life, and the chemical properties of silicone are stable and applicable to a wide range of scenarios.

[0084] In some examples, such as Figure 1 and Figure 2 As shown, the display module further includes a waterproof layer 121 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 portion 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 containing more water vapor and improve reliability. Exemplarily, the display device is a kitchen utensil, such as an intelligent cooking machine, an air fryer, and an electric rice cooker. The water vapor generated when the kitchen utensil is working will be blocked by the protective cover 140 and the waterproof layer 121 in turn to avoid entering the display assembly 130, thereby ensuring that the display assembly 130 can still display normally in this usage scenario and improving stability.

[0086] Exemplarily, the waterproof layer 121 may be made of waterproof glue, such as model 5520PSB water-retaining glue or model 5525PSB water-retaining glue.

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

[0088] It is understood that the display component 130 is provided with a first polarizer 131, a second polarizer 132, a display panel 133 and a backlight 134. Specifically, the display panel 133 is provided with a color filter, a liquid crystal layer and a thin film transistor glass. Among them, a conductive film can be formed on the thin film transistor glass by sputtering and chemical deposition processes, and various large-scale circuits can be made by processing the conductive film, which can greatly reduce the cost. Each liquid crystal pixel of the display component 130 is driven by a thin film transistor, so that the screen information can be displayed at high speed, high brightness and high contrast. The color filter is arranged on the side of the thin film transistor glass close to the cover plate 120, and the color filter is provided with a plurality of three primary color units arranged in an array. By adjusting the light intensity passing through the color unit, the color unit can be displayed as the required color. The liquid crystal layer is arranged between the color filter and the thin film transistor glass. The first polarizer 131 is arranged on the side of the color filter close to the cover plate 120, and the backlight 134 is arranged on the side of the thin film transistor glass away from the cover plate 120. A second polarizer 132 is disposed between the backlight 134 and the thin film transistor glass. Under the action of the electric field, the liquid crystal molecules will change in arrangement, thereby affecting the change in 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, the light can be changed in brightness, and through the effect of the color filter, the display component 130 can achieve the purpose of displaying different color information.

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

[0090] It can be understood that the backlight 134 is provided with a film material, a plurality of reflective sheets and a light guide plate 1342. Among them, the plurality of reflective sheets 1341 can be arranged to form a reflective groove. Specifically, the reflective groove can be surrounded by four reflective sheets 1341, one of which serves as the groove bottom of the reflective groove, and the remaining three reflective sheets 1341 serve as the side walls of the reflective groove, so that the reflective groove is formed with a first opening and a second opening, wherein the first opening is formed at the top of the reflective groove and is arranged toward the film material, and the second opening is formed at the side of the reflective groove and is used to face the light source. The light guide plate 1342 is placed in the reflective groove so that the three sides of the light guide plate 1342 have corresponding reflective sheets 1341. And the light source corresponds to the side of the light guide plate 1342 at the second opening, so that the light emitted by the light source can illuminate the light guide plate 1342. In this way, the light emitted by the light source located on the side of the light guide plate 1342 can be converted into a surface light source that radiates the film material through the action of the light guide plate 1342, and the light emitted from the other three sides of the light guide plate 1342 is reflected back to the light guide plate 1342 through the action of the reflective sheets in multiple directions of the reflection groove, so that the light on the side is reused after reflection, reducing light loss, improving light utilization, and increasing light intensity. For example, the material of the light guide plate 1342 can be PC, with a thickness of 1.8 mm.

[0091] It can be understood that the film material is provided with a diffuser 1347, a first prism 1348, and a second prism 1349. Among them, the first prism 1348 is close to the light guide plate 1342 on the first open side, 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 focus the light emitted from the light guide plate 1342, thereby improving the brightness of the light. In addition, the diffuser 1347 widens the field of view and makes the light relatively balanced on the entire plane, thereby improving the uniformity of the light after passing through the first prism 1348 and the second prism 1349.

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

[0093] It can be understood that the backlight 134 is also provided with a frame 1343, a back plate 1344 and an edge tape 1345. Among them, the first polarizer 131, the second polarizer 132 and the display panel 133 are arranged in the frame 1343, and a protrusion is formed on the inner side of the frame 1343 as a support position. Specifically, the second polarizer 132 abuts against the protrusion, thereby determining the position of the second polarizer 132 in the frame 1343. The back plate 1344 is formed with a bending section, and the bending direction of the bending section faces the frame 1343. The back plate 1344 abuts against the side of the protrusion away from the second polarizer 132 through the bending section, thereby determining the relative position of the back plate 1344 and the frame 1343. The side of the reflective groove away from the opening can be glued to the back plate 1344 to fix the backlight 134 to the back plate 1344, so as to ensure that the light passing through the backlight 134 can be irradiated to the second polarizer. One end of the edge tape 1345 is bonded to the side of the back plate 1344 away from the bottom of the reflective groove, and the other end of the edge tape 1345 is bonded to the top of the frame 1343 and the display panel 133, and the edge tape 1345 wraps the outside of the frame 1343, and the relative positions of the back plate 1344 and the frame 1343 and the relative positions of the frame 1343 and the display panel 133 are fixed by the edge tape 1345. Thus, the fastness and stability of the connection are improved.

[0094] It is understandable that a black double-sided tape is provided between the supporting positions of the second polarizer 132 and the frame 1343 to adhere the second polarizer 132 and the frame 1343 to each other, so that the second polarizer 132 and the frame 1343 are firmly connected to improve reliability.

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

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

[0097] It is understandable that the display module is also provided with a touch substrate 150. Specifically, the touch substrate 150 is located between the cover plate 120 and the first polarizer 131. The user 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. The operation is more convenient and the user experience is improved. A placement groove 112 is formed on the side of the bracket 110 close to the cover plate 120 to provide an installation space for the display component 130. And a first hollow 1121 and a second hollow 1122 may be provided at the bottom of the placement groove 112. Among them, the first flexible circuit board 151 of the touch substrate 150 can be connected to the control main board 160 through the first hollow 1121, and the second flexible circuit board 1331 of the display panel 133 can be connected to the control main board 160 through the second hollow 1122, and there will not be too many lines exposed on the side of the bracket 110, making the wiring more reasonable.

[0098] It is understandable that the location, shape and size of the placement slot 112 can be determined according to specific product requirements. Figure 7 As shown, the area of ​​the placement slot 112 is i, and the area of ​​the area i accounts for 2 / 3 to 4 / 5 of the area of ​​the side of the bracket 110 where the placement slot 112 is opened. The area of ​​the first hollow 1121 accounts for 3 / 500 to 1 / 50 of the area of ​​the placement slot 112, and the area of ​​the second hollow 1122 accounts for 2 / 50 to 8 / 50 of the area of ​​the placement slot 112.

[0099] Exemplarily, 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. The capacitive touch glass 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, and deterioration problems after long-term use.

[0100] In some examples, such as Figure 5 As shown, an avoidance pit 1123 is formed in the placement groove 112 for accommodating components of the display panel 133 .

[0101] It is understandable that a avoidance pit 1123 may be formed in the placement groove 112 of the bracket 110, thereby forming a storage space for components of the display panel 133. Some components of the display panel 133 may protrude from the display panel 133. When the display assembly 130 is installed in the placement groove 112, these components may be placed in the avoidance pit 1123, thereby making the connection between the display assembly 130 and the bracket 110 more stable and arranging the installation space reasonably. The size and position of the avoidance pit 1123 may be determined according to the size and position of the components protruding from the surface of the display panel 133 to improve adaptability.

[0102] Exemplarily, 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 display module also includes: a control main board 160, a mounting position 113 is formed on the side of the bracket 110 away from the cover plate 120, the control main board 160 is placed in the mounting position 113, and the first flexible circuit board 151 and the second flexible circuit board 1331 are electrically connected to the control main board 160 respectively.

[0104] It is understandable that the display module is also provided with a control mainboard 160. Specifically, a mounting position 113 may be formed on the side of the bracket 110 away from the display assembly 130, the control mainboard 160 may be placed in the mounting position 113, and the first flexible circuit board 151 may pass through the first hollow 1121 and be located in the mounting position 113, and connected to the control mainboard 160. The second flexible circuit board 1331 may pass through the second hollow 1122 and be located in the mounting position 113, and be connected to the control mainboard 160. Such a layout reduces the overall thickness of the display module and reduces the length of the exposed line. The user can observe the parameters displayed by the display assembly 130 through the cover plate 120 and the touch substrate 150, and the touch substrate 150 can be operated by touching the cover plate 120. The touch substrate 150 can send the user's adjustment information to the control mainboard 160. While adjusting the parameters through the control mainboard 160, the control mainboard 160 can control the display assembly 130 to display the adjusted parameters to feedback to the user.

[0105] Exemplarily, the display device is a smart cooking machine, and the display component 130 can display various working parameters of the smart cooking machine, such as stir-frying time. The user can touch the cover 120 to operate the touch substrate 150 to adjust the stir-frying time. The touch substrate 150 can send the user-adjusted stir-frying time information 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 understand the adjusted stir-frying time more intuitively, thereby improving 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 mainboard 160 and the bracket 110 ; and a fixing member, for fixing the control mainboard 160 to the bracket 110 .

[0107] It is understandable that the display module is also provided with a limiter and a fixing member. Specifically, a limiter is provided at the mounting position 113, and the position of the control mainboard 160 in the mounting position 113 is limited by the limiter. At the same time, the control mainboard 160 can be fixed in the mounting position 113 by the fixing member to ensure that the position of the control mainboard 160 relative to the bracket 110 is fixed. In this way, the connection between the control mainboard 160 and the first flexible circuit board 151 and the second flexible circuit board 1331 is stable, and the stable operation of the display module is ensured, thereby improving reliability.

[0108] In some examples, such as Figures 9 to 11 As shown, the above-mentioned limiting member is a stopper 170, and the above-mentioned stopper 170 is provided with a slot 171, and one end of the above-mentioned control main board 160 is clamped in the above-mentioned slot 171; and / or, the above-mentioned fixing member is a bolt 180, and the above-mentioned mounting position 113 is provided with a threaded hole, and the other end of the above-mentioned bolt 180 passes through the above-mentioned control main board 160 and is screwed into the above-mentioned threaded hole.

[0109] It is understandable that the stopper may be a stopper 170, and two stoppers 170 may be provided. The two corners on the same side of the control mainboard 160 may abut against one stopper 170 respectively, thereby limiting the control mainboard 160 from moving along the length direction of the bracket 110. After the stopper 170 limits the position of the control mainboard 160, the control mainboard 160 is fixed by a fixing member. Specifically, a through hole may be provided at one end of the control mainboard 160 away from the stopper 170, and a threaded hole may be provided at the mounting position 113. When the control mainboard 160 abuts against the stopper 170, the through hole may correspond to the threaded hole. The stopper 170 is provided to facilitate positioning of the control mainboard 160, and to facilitate fast fixing of the control mainboard 160 using a fixing member, thereby improving assembly efficiency. The fixing member may be a bolt 180, and the bolt 180 is screwed into the threaded hole after passing through the through hole to fix the control mainboard 160 to the bracket 110. This ensures that the connection between the control mainboard 160 and the first flexible circuit board 151 and the second flexible circuit board 1331 is stable, thereby ensuring stable operation of the display module and improving reliability.

[0110] It can be understood that the stopper 170 can be a hexahedral hollow structure, and the bottom of the stopper 170 is connected to the bracket 110. In addition, the bottom of the stopper 170 and the position of the bracket corresponding to the bottom of the stopper 170 are provided with a production hole 172, and the production hole 172 is connected to the hollow part inside the stopper 170, so as to facilitate the mold opening of the bracket 110 mold and the production of the bracket 110. The stopper 170 faces the control main board 160, and the side close to the control main board 160 is the first surface, and the side adjacent to the first surface and close to the control main board 160 is the second surface. Among them, the first surface is provided with a first opening, and the side of the first opening close to the bracket is provided with a first retaining wall 173; the second surface is provided with a second opening, and the side of the second opening away from the first surface is provided with a second retaining wall 174, and the first opening and the second opening together form a slot 171, and the corners of the control main board 160 can be snapped into the slot 171, thereby improving the limiting ability of the stopper 170 to the control main board 160.

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

[0112] In some examples, such as Fig. 9 As shown, the display module further includes: a mounting member 190, which is disposed on a side of the bracket 110 away from the cover plate 120, and is used to mount the bracket 110 on a counterpart.

[0113] It is understandable that the display module is also provided with a mounting member 190. Specifically, the mounting member 190 is located on the side of the bracket 110 away from the display assembly 130, and the display module can be mounted on the counterpart through the mounting member 190 to form a display device, ensuring that the display module and the counterpart are firmly connected and reliability is improved.

[0114] In some examples, such as Figure 8 As shown, the mounting member 190 includes: a mounting column 191, which is provided with an internal thread for threaded connection with the counterpart; and a buckle 192 for clamping with the counterpart.

[0115] It is understandable that the mounting member 190 may be provided with a mounting post 191, which protrudes from the side of the bracket 110 away from the display assembly 130, and the mounting post 191 is provided with an internal thread, and correspondingly, the counterpart is provided with a mounting hole, and when the display assembly 130 is mounted on the counterpart, the mounting post 191 is passed through the mounting hole and screwed on the internal thread by the bolt 180. The mounting member 190 is also provided with a buckle 192, and a buckle position is formed at the corresponding position of the counterpart, and the buckle 192 can be buckled in the buckle position. Through two connection methods, the display module is mounted on the counterpart, which improves the connection tightness and reliability.

[0116] Exemplarily, four mounting posts 191 are provided, respectively located at the four corners of the bracket 110. Four buckles can be provided, respectively symmetrically arranged at the middle position of the bracket 110, so as to ensure that the display module and the pair of components are connected with uniform force and improve stability.

[0117] In some examples, such as Figure 3 and Figure 4 As shown, the display module further includes: a knob 200, electrically connected to the control main board 160; a fixing sleeve 114, arranged on the bracket 110, the cover plate 120 is provided with a first through hole, the non-display area of ​​the touch substrate 150 is provided with a second through hole, the fixing sleeve 114 is passed through the first through hole and the second through hole, and the knob 200 is passed through the fixing sleeve 114.

[0118] It is understandable that the display module is also provided with a knob 200, and the knob 200 is electrically connected to the control mainboard 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, and a second through hole is provided in the non-display area of ​​the touch substrate 150. The fixing sleeve 114 can pass through the second through hole and the first through hole in sequence and is located at the top of the cover plate 120. The knob 200 can be inserted into the fixing sleeve 114, and the circumferential displacement of the knob 200 is limited by the fixing sleeve 114, and the knob 200 is limited to rotate only around its own axis. The user can adjust the parameters of the display device by rotating the knob 200, and the display component 130 displays the adjusted parameters, which is easy to operate and improves the user's operating sense.

[0119] For example, the display device is an intelligent cooking machine, and the cooking temperature can be adjusted by turning the knob 200, and the user can observe the current cooking temperature and the degree of firepower displayed by the display component 130 through the cover 120. After the user turns the knob 200 to adjust the cooking temperature, the control mainboard 160 controls the intelligent cooking machine to adjust the power to change the cooking temperature to the temperature adjusted by the user. At the same time, the control mainboard 160 controls the display component 130 to display the adjusted cooking temperature and degree of firepower.

[0120] like Figure 8 As shown, exemplarily, the area where the bracket 110 is provided with the fixing sleeve 114 is j, and the area of ​​the bracket 110 for placing the components of the display panel 133 is k. In the projection in the horizontal plane direction, the areas of j and k are approximately equal, and the ratio of the area of ​​the bracket 110 located in the area j or the area k to the area between the area j and the area k can range from 3 / 19 to 3 / 16.

[0121] In some examples, such as Fig.14 As shown, the display module further includes: a plurality of interfaces 161, which are arranged on the control main board 160; a shielding cover 162, which covers the components of the control main board 160; and a base plate 210, which is connected to the bracket 110 and covers the side of the control main board 160 away from the bracket 110.

[0122] It is understandable that the display module is also provided with a plurality of interfaces 161, and the control mainboard 160 may be integrated with a plurality of control modules, which may control a plurality of functions of the display device, and the functional unit of the display device may be electrically connected to the control module corresponding to the control mainboard 160 through the interface 161. Exemplarily, the interface 161 is provided with 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 bottom plate 210 may be provided on the side of the control mainboard 160 away from the bracket 110, and the bottom plate 210 covers the control mainboard 160, provides shielding for the control mainboard 160, thereby providing protection for the control mainboard 160 and extending the service life of the control mainboard 160.

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