Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a display device. Background Technology

[0002] As a key diagnostic technology, the performance of the main display screen in ultrasound imaging directly affects diagnostic accuracy. Existing conventional monitors often have a stand fixed to the center of the back of the screen. While this provides stability, the power and signal cables are exposed and prone to loosening or detaching during rotation, causing image interruption. Since ultrasound equipment is used for real-time diagnosis, detached cables could endanger patient safety, and exposed cables also hinder overall sterilization and integration.

[0003] Therefore, ultrasound equipment typically embeds cables within the hinge of the main screen's bracket. This requires the system boards to be placed on the upper part of the back panel with the interfaces facing downwards, and space must be reserved below for cable routing. Consequently, the bracket and main screen must be fixed even lower, resulting in a lower support point for the bracket on the main screen and reduced stability of the bracket's support. Utility Model Content

[0004] This application aims to at least partially solve the technical problem of low stability of the support bracket for the main screen in related technologies. To this end, this application provides a display device.

[0014] In some embodiments, the display device further includes a fastener connecting the reinforcing plate and the back plate, wherein a first window is provided on the fixing plate, and the fastener is exposed in the first window.

[0015] In some embodiments, the reinforcing plate has a second window and a first locking hole communicating with the second window, the second window being exposed above the first window, the back plate having a second locking hole, and the fastener passing through the first locking hole and the second locking hole.

Along the thickness direction of the housing, the projection of the first reinforcing rib on the fixing plate is located within the gap.

[0019] In some embodiments, the display device further includes a first protective cover connected to the fixing plate and covering the main board. The housing is provided with a second reinforcing rib on the side near the fixing plate. Along the thickness direction of the housing, the projection of the first protective cover on the housing and the projection of the second reinforcing rib on the housing at least partially coincide. Along the height direction of the housing, at least a portion of the first protective cover and the second reinforcing rib are spaced apart.

[0020] In some embodiments, the fixing plate is provided with a first mounting port, and the backlight driving plate is mounted in the first mounting port.

[0040] In the field of ultrasound diagnostic equipment, ultrasound imaging, as one of the three major medical imaging technologies, is a key means of early lesion screening and diagnosis. The image display quality of its main screen directly affects the accuracy of doctors' lesion localization and disease assessment. A typical ultrasound device consists of a main ultrasound screen (used to display diagnostic images), a secondary screen (displaying the operating interface), a support, a probe, a control panel, a main unit, and a mobile vehicle. The support not only supports the main screen and allows for its left and right rotation adjustment to meet the multi-angle observation needs of doctors, nurses, assistants, and patients, but also serves to store internal cables.

[0041] Currently, ordinary desktop monitors often use a centrally mounted stand connection, which, while providing a certain degree of structural stability, typically exposes power and signal cables, making them prone to detachment when the screen rotates, leading to image interruption. Ultrasound equipment, used for real-time monitoring of patient vital signs, is particularly vulnerable to cable detachment, which could disrupt the diagnostic process and jeopardize medical safety. Furthermore, exposed cables affect the overall integrity of the equipment and increase the difficulty of cleaning and disinfection. Therefore, ultrasound equipment typically integrates cables within the stand hinge, with internal wiring connecting to the main unit.

[0042] This design requirement necessitates placing the system boards on the upper part of the display backplane, with power and signal interfaces extending from their lower ends. Space must be reserved for cable retraction, and the connection is ultimately achieved via a bracket fixing point located at a lower position on the backplane. While this layout satisfies the requirements for cable concealment and overall system integration, the low support point weakens the structural stability of the display module. To address these issues in related technologies, this application provides a display device that improves the rigidity and load-bearing capacity of the bracket fixing point, thereby enhancing the support stability of the display module.

[0043] This application is described below with reference to the accompanying drawings and specific embodiments:

[0044] Please see Figure 1This application provides a display device 10. The display device 10 provided in this application can be the main screen of an ultrasound device, or the display terminal of other medical imaging devices, such as an endoscope display, a vital signs monitor screen, etc. It can also be the display screen of other professional equipment with high requirements for display stability and reliability, such as an industrial control touch screen, an aerospace instrument screen, a high-performance graphics workstation display, etc. There are no limitations on this.

[0045] Please see Figure 1 In this embodiment, the display device 10 includes a housing 700, a display module 200, a fixing plate 100, and a bracket. The housing 700 has a mounting cavity and a transition hole 710 communicating with the mounting cavity, and the display module 200 is disposed within the mounting cavity. The fixing plate 100 is disposed within the mounting cavity and connected to the housing 700, and the strength of the fixing plate 100 is greater than the strength of the housing 700. The bracket passes through the transition hole 710 and is connected to the fixing plate 100.

[0046] The housing 700 is a basic component of the display device 10, providing protection and a mounting base for at least other components of the display device 10. The housing 700 includes a rear shell and a front frame, which form a mounting cavity. The housing 700 is generally rectangular. For ease of description, the height direction Z, width direction X, and thickness direction Y are defined. In the usage state of the display device 10, the vertical direction of the housing 700 is the height direction Z, and the projection of the housing 700 in the vertical direction is a rectangle, with the direction of the longer side being the width direction X, and the direction of the wider side being the thickness direction Y. Similarly, for ease of description, four directions are defined: up, down, left, and right. In the height direction Z, the area closer to the top surface of the housing 700 is designated as up, and the area farther from the top surface is designated as down. In the width direction X, the two directions are left and right, respectively.

[0047] Please see Figure 2 and Figure 3 The display module 200 is used for image generation. The display module 200 has a display surface 220 for displaying images. A front frame is disposed on the display surface 220 of the display module 200, and a rear cover is disposed on the side of the display module 200 opposite to the display surface 220. The display module 200 includes a back plate 210, which is disposed on the side of the display module 200 opposite to the display surface 220.

[0048] The housing 700 can be made of plastic for easy processing and shaping, while the fixing plate 100 can be made of stainless steel, thus the strength of the fixing plate 100 can be greater than that of the housing 700. The bracket supports the display device 10 and can be positioned near the rear housing, with the bracket positioned lower. A transition hole 710 is located in the rear housing, and the fixing plate 100 is located on the side of the back plate 210 away from the display surface 220. The fixing plate 100 is connected to the rear housing, so the bracket can pass through the transition hole 710 to enter the mounting cavity and connect with the fixing plate 100, thus achieving fixed installation of the bracket.

[0049] Please see Figure 4 Optionally, the bracket includes a bracket body and a fastener. The bracket body has a first fixing hole, and the fixing plate 100 has a second fixing hole 111. The fastener passes through the first fixing hole, the transition hole 710, and the second fixing hole 111 to connect the bracket body and the fixing plate 100. The bracket may have two fixing positions on the fixing plate 100, and each of the two fixing positions is provided with multiple second fixing holes 111 to enhance the connection strength. Of course, multiple transition holes 710 and second fixing holes 111 may be provided correspondingly. The first fixing hole and the second fixing hole 111 can be screw holes, and the fastener can be a screw.

[0050] In this embodiment, since the bracket passes through the transition hole 710 and is connected to the fixing plate 100, the fixing point of the bracket is transferred from the housing 700 to the fixing plate 100. The fixing plate 100 becomes the direct load-bearing body, effectively dispersing and transferring the concentrated load borne by the bracket to a larger area of ​​the housing 700 through its greater rigidity. This greatly reduces the stress and deformation in the local area of ​​the housing 700 and improves the overall stability of the support.

[0051] Please see Figure 4 In some embodiments, the fixing plate 100 is provided with a first protrusion 110, and the bracket is connected to the first protrusion 110.

[0052] The second fixing hole 111 is provided at the first protrusion 110, which protrudes away from the display module 200 to form a reinforcing structure, effectively improving the rigidity and structural strength of this area on the fixing plate 100. The bracket is fixedly connected to the first protrusion 110, so that the fixing base point of the bracket can be set in a more rigid part, significantly improving the load-bearing capacity and deformation resistance of the bracket fixing point, thereby making the support of the bracket for the display module 200 more stable and reliable.

[0053] Optionally, the first protrusion 110 may be approximately rectangular, and since the bracket has two fixed positions on the fixing plate 100, the fixing plate 100 is provided with two first protrusions 110, which are spaced apart along the width direction X.

[0054] Please see Figure 1 and Figure 4 In some embodiments, the fixing plate 100 is provided with a plug-in portion 120 and a first connecting portion 130, and the housing 700 is provided with a plug-in groove and a second connecting portion 720. The plug-in portion 120 is plugged into the plug-in groove, and the first connecting portion 130 is connected to the second connecting portion 720.

[0055] The insertion part 120 engages with the insertion slot to position the fixing plate 100 on the housing 700, improving the positioning accuracy of the fixing plate 100 on the housing 700. The connection between the first connecting part 130 and the second connecting part 720 secures the fixing plate 100 to the housing 700. That is, when installing the fixing plate 100 onto the rear housing, the insertion part 120 is first engaged with the insertion slot to determine the position, and then the first connecting part 130 and the second connecting part 720 are connected to ensure stable installation of the fixing plate 100.

[0056] The fixing plate 100 is generally rectangular. Both the insertion portion 120 and the first connecting portion 130 are located on the side of the fixing plate 100, and both protrude from the side of the fixing plate 100. Multiple insertion portions 120 and first connecting portions 130 can be provided. The insertion portion 120 can be located on the lower side of the fixing plate 100, and the multiple first connecting portions 130 are distributed on the remaining sides of the fixing plate 100. The insertion slot and the second connecting portion 720 are positioned correspondingly on the housing 700.

[0057] Optionally, a first connecting hole 131 may be provided on the first connecting portion 130, and a second connecting portion 720 may be a second connecting hole. The display device 10 also includes a connector that passes through the first connecting hole 131 and the second connecting hole, thereby achieving a fixed connection between the fixing plate 100 and the housing 700. Please refer to [link / reference]. Figure 5 At least one of the first connecting portions 130 may also be provided with a positioning hole 132 to cooperate with the positioning post on the housing 700, so as to further improve the positioning accuracy of the fixing plate 100. The first connecting hole 131 and the second connecting hole may be screw holes, and the connecting element is a screw.

[0058] The first connecting hole 131 can be a U-shaped hole. This structural design allows for a certain positional tolerance before the connector is inserted, facilitating assembly alignment. The first connecting hole 131 has an opening. The opening of the first connecting hole 131 located on the upper side faces upward, which enables coarse positioning of the fixing plate 100 in the thickness direction Y. The opening of the first connecting hole 131 located on the left side faces left, and the opening of the first connecting hole 131 located on the right side faces right. The first connecting holes 131 on the left and right sides together achieve coarse positioning of the fixing plate 100 in the width direction X, thereby improving the positioning accuracy of the fixing plate 100.

[0059] In some embodiments, the fixing plate 100 is connected to the back plate 210 of the display module 200. That is, one side of the fixing plate 100 is connected to the back plate 210, and the other side is connected to the housing 700. The back plate 210 provides rigid support for the display module 200 and has high strength, rigidity, and hardness. The fixing plate 100 and the back plate 210 can be directly connected by multiple screws. In this way, when the bracket is subjected to force, it is directly transmitted to the fixing plate 100. The fixing plate 100 evenly distributes the force across the entire plane, and then transmits it to the back plate 210 through multiple connection points. This avoids stress concentration and significantly improves the overall rigidity and stability of the display device 10.

[0060] When installing the display device 10, the fixing plate 100 can be connected to the back plate 210 of the display module 200 first, then the fixing plate 100 and the display module 200 can be assembled into the back shell, and finally the front frame can be installed on the front of the display device 10.

[0061] Please see Figure 3 and Figure 4 In some embodiments, the display device 10 further includes a reinforcing plate 300, which connects the fixing plate 100 and the back plate 210. The reinforcing plate 300 is configured to correspond to the connection position of the bracket on the fixing plate 100.

[0062] A reinforcing plate 300 is disposed between the fixed plate 100 and the back plate 210, and connects the fixed plate 100 and the back plate 210. The reinforcing plate 300 can be riveted to the fixed plate 100. The connection position of the bracket on the fixed plate 100 is the first protrusion 110, so the reinforcing plate 300 is correspondingly disposed to the first protrusion 110. Since there are two first protrusions 110, and the two first protrusions 110 are spaced apart along the width direction X, the reinforcing plate 300 can be a long strip steel plate disposed along the width direction X, covering both first protrusions 110, thus achieving a corresponding arrangement with the two first protrusions 110.

[0063] The reinforcing plate 300 can be made of steel, which has high strength and rigidity. Therefore, by installing the reinforcing plate 300 at the connection position of the bracket on the fixed plate 100, the structural strength of the bracket connection position on the fixed plate 100 can be improved, thereby further enhancing the structural stability. Optionally, the thickness of the reinforcing plate 300 can be 1.8mm.

[0064] Please see Figure 3 and Figure 4 In some embodiments, the display device 10 further includes a fastener that connects the reinforcing plate 300 and the back plate 210. A first window 140 is provided on the fixing plate 100, through which the fastener is exposed.

[0065] When installing the reinforcing plate 300, it is first connected to the fixing plate 100, and then the fixing plate 100 and the reinforcing plate 300 are connected to the back plate 210. Since the reinforcing plate 300 is located between the fixing plate 100 and the back plate 210, a first window 140 needs to be provided on the fixing plate 100 to facilitate finding the connection position between the reinforcing plate 300 and the back plate 210. In this way, the connection position between the reinforcing plate 300 and the back plate 210 can be viewed through the first window 140, which facilitates the installation of fasteners to connect the reinforcing plate 300 and the back plate 210.

[0066] To avoid interference between the connection between the reinforcing plate 300 and the back plate 210 and the connection between the first protrusion 110 and the bracket, the connection position between the reinforcing plate 300 and the back plate 210 can be set between the two first protrusions 110, so that the first window 140 is also set between the two first protrusions 110.

[0067] In some embodiments, the reinforcing plate 300 is provided with a second window 310 and a first locking hole 320 communicating with the second window 310. The second window 310 is exposed above the first window 140. The back plate 210 is provided with a second locking hole, and fasteners pass through the first locking hole 320 and the second locking hole.

[0068] Fasteners pass through the first locking hole 320 and the second locking hole, thus connecting the reinforcing plate 300 and the back plate 210. The first and second locking holes can be screw holes, and the fasteners can be screws. When connecting the reinforcing plate 300 and the back plate 210, the first and second locking holes must be aligned. Therefore, a second window 310 is opened on the reinforcing plate 300, and the first locking hole 320 communicates with the second window 310. This allows the position of the second locking hole to be observed through the second window 310, ensuring alignment of the first and second locking holes. Of course, the second window 310 must be exposed above the first window 140 to be observable.

[0069] Optionally, there are two first locking holes 320, which are respectively located on both sides of the second window 310 along the width direction X, and the first locking holes 320 are U-shaped holes to provide a certain positional tolerance and facilitate assembly alignment.

[0070] Please see Figure 6In some embodiments, the display device 10 further includes a motherboard 400 and a backlight driver board 500, which are mounted on the side of the mounting plate 100 away from the display module 200. The motherboard 400 is responsible for signal processing and system control, while the backlight driver board 500 provides precise current and voltage to the backlight. Since the mounting plate 100 is connected to the backplate 210, the motherboard 400 and the backlight driver board 500 can be mounted on the mounting plate 100, and the motherboard 400 and the backlight driver board 500 are located on the side of the mounting plate 100 away from the display module 200, thereby facilitating the installation of the motherboard 400 and the backlight driver board 500.

[0071] Optionally, the motherboard 400 and the backlight driver board 500 can be attached to the fixing plate 100 by screws. The motherboard 400 can be located in the middle of the upper part of the fixing plate 100, and the backlight driver board 500 can be located in the middle left of the fixing plate 100.

[0072] Please see Figure 4 and Figure 6 In some embodiments, the fixing plate 100 is provided with a second protrusion 150, and the main board 400 and the backlight driver board 500 are mounted on the second protrusion 150.

[0073] The motherboard 400 and the backlight driver board 500 need to be connected to the components in the display module 200 via cables. Therefore, there needs to be a space in the thickness direction Y between the fixing plate 100 and the back plate 210 to allow the cables to pass through. The second protrusion 150 protrudes away from the back plate 210. Correspondingly, a groove is formed on the side of the second protrusion 150 near the back plate 210, thereby forming a space with a thickness direction Y width between the second protrusion 150 and the back plate 210, so that the cables can pass through.

[0074] Optionally, the second protrusion 150 may be generally rectangular, and the size of the second protrusion 150 may be relatively large, that is, the second protrusion 150 may occupy most of the area of ​​the fixing plate 100. The first protrusion 110 may also be provided on the basis of the second protrusion 150, so that the cable has enough space to pass through.

[0075] In some embodiments, the second protrusion 150 has a clearance interval 151 between it and the side of the fixing plate 100, and the housing 700 is provided with a first reinforcing rib on the side near the fixing plate 100. Along the thickness direction of the housing 700, the projection of the first reinforcing rib on the fixing plate 100 is located within the clearance interval 151.

[0076] The housing 700 is provided with a first reinforcing rib for strengthening the structure. The second protrusion 150 and the side of the fixing plate 100 have a clearance interval 151. The area of ​​the clearance interval 151 is a flat surface. The flat surface and the second protrusion 150 have a height difference in the thickness direction Y, thereby forming a stepped structure.

[0077] Along the thickness direction Y of the housing 700, the projection of the first reinforcing rib onto the fixing plate 100 lies within the clearance interval 151. That is, the first reinforcing rib is located within the clearance interval 151. The first reinforcing rib can contact a flat surface within the clearance interval 151, or it can be spaced apart from the flat surface. This design provides clearance space for the first reinforcing rib in the thickness direction Y of the fixing plate, thereby allowing the housing 700 to be closer to the fixing plate 100 in the thickness direction Y, thus reducing the overall thickness of the display device 10.

[0078] Optionally, the housing 700 is provided with first reinforcing ribs on both the left and right sides, and the second protrusion 150 is spaced from the left and right sides of the fixing plate 100, thereby forming a stepped structure 151 on both the left and right sides of the fixing plate 100 to avoid the first reinforcing ribs on the left and right sides of the housing 700 respectively.

[0079] Please see Figure 4 and Figure 6 In some embodiments, the display device 10 further includes a first protective cover 410, which is connected to the fixing plate 100 and covers the main board 400. The housing 700 is provided with a second reinforcing rib on the side near the fixing plate 100. Along the thickness direction Y of the housing 700, the projection of the first protective cover 410 on the housing 700 and the projection of the second reinforcing rib on the housing 700 at least partially overlap. Along the height direction Z of the housing 700, at least a portion of the first protective cover 410 and the second reinforcing rib are spaced apart.

[0080] The housing 700 is also provided with a second reinforcing rib for structural reinforcement. The first protective cover 410 is connected to the fixing plate 100 and covers the main board 400, thereby protecting the main board 400. Of course, the backlight driver board 500 is also equipped with a second protective cover 510 for its protection. Both the first protective cover 410 and the second protective cover 510 can be connected to the fixing plate 100 by screws.

[0081] Along the thickness direction Y of the housing 700, the projection of the first protective cover 410 on the housing 700 and the projection of the second reinforcing rib on the housing 700 at least partially overlap. Along the height direction Z of the housing 700, at least a portion of the first protective cover 410 and the second reinforcing rib are spaced apart, that is, at least a portion of the first protective cover 410 and the second reinforcing rib overlap in the thickness direction Y, and at least a portion of the first protective cover 410 avoids the second reinforcing rib in the thickness direction Y, so that the second reinforcing rib can be spaced apart from at least a portion of the first protective cover 410 in the height direction Z, making the housing 700 closer to the fixing plate 100 in the thickness direction Y, further reducing the overall thickness of the display device 10.

[0082] Optionally, the first protective cover 410 has a main body plane 413 and a clearance slope 411 arranged at an angle. The main body plane 413 is arranged parallel to the side of the housing 700 near the fixing plate 100. The second reinforcing rib is correspondingly arranged with the clearance slope 411. That is, along the thickness direction Y of the housing 700, the projection of the clearance slope 411 on the housing 700 and the projection of the second reinforcing rib on the housing 700 at least partially coincide. Along the height direction Z of the housing 700, the main body plane 413 and the second reinforcing rib are spaced apart. The main plate 400 can be arranged on the upper part of the fixing plate 100, that is, the first protective cover 410 is arranged on the upper part of the fixing plate 100, and the second reinforcing rib is also arranged on the upper part of the housing 700. Thus, the clearance slope 411 on the first protective cover 410 can avoid the second reinforcing rib.

[0083] It should be noted that because the first protective cover 410 requires the machining of the avoidance slope 411, the first protective cover 410 cannot be integrally formed. In other words, the first protective cover 410 cannot be made from a single piece of material. Therefore, the first protective cover 410 can be a split structure, consisting of two parts. One part is made into a cover body with the avoidance slope 411, and the other part is made into an overlap 412 for connecting with the fixing plate 100. The two parts are riveted together to form the first protective cover 410. This design can improve the utilization rate of the material and reduce costs.

[0084] Please see Figure 7 In some embodiments, the fixing plate 100 is provided with a first mounting port 160, and the backlight driving plate 500 is mounted in the first mounting port 160.

[0085] The backlight driver board 500 is used to drive LEDs and consumes a lot of power. Therefore, the components on the backlight driver board 500 are large, such as large connectors, large inductors, and large capacitors 530. As a result, the backlight driver board 500 occupies a large space in the thickness direction Y. Consequently, the second protective cover 510 needs to be deeper in the thickness direction Y, which is not conducive to the overall thinning of the display module 200.

[0086] Therefore, the fixing plate 100 is provided with a first mounting opening 160, which extends through both sides of the fixing plate 100 along the thickness direction Y. The backlight driving plate 500 is installed in the first mounting opening 160. That is, the space between the fixing plate 100 and the back plate 210 can absorb part of the thickness of the backlight driving plate 500, so that the thickness of the backlight driving plate 500 protruding from the fixing plate 100 on the side of the fixing plate 100 away from the back plate 210 is reduced, thereby reducing the depth of the second protective cover 510 in the thickness direction Y, so that the housing 700 is closer to the fixing plate 100 in the thickness direction Y, further reducing the overall thickness of the display device 10.

[0087] Optionally, a fixing piece 522 may be provided on the inner wall of the first mounting port 160. The fixing piece 522 overlaps the backlight driving board 500, and the fixing piece 522 and the backlight driving board 500 are fixed by screws, thereby realizing the installation of the backlight driving board 500 in the first mounting port 160.

[0088] In some embodiments, the backlight driver board 500 includes a first substrate 520 and a capacitor 530 disposed on the first substrate 520. The first substrate 520 is provided with a second mounting port 521, and the capacitor 530 is mounted in the second mounting port 521.

[0089] The capacitor 530 has a relatively large size in the thickness direction Y. Therefore, a second mounting port 521 is provided on the first substrate 520. The second mounting port 521 extends through both sides of the first substrate 520 in the thickness direction Y. The capacitor 530 is installed in the second mounting port 521. Thus, the space between the first substrate 520 and the back plate 210 can absorb part of the thickness of the capacitor 530. This reduces the thickness of the capacitor 530 protruding from the first substrate 520 on the side of the first substrate 520 away from the back plate 210. This reduces the depth of the second protective cover 510 in the thickness direction Y, making the housing 700 closer to the fixing plate 100 in the thickness direction Y, and further reducing the overall thickness of the display device 10.

[0090] Optionally, a fixing adhesive can be applied to the capacitor 530 to bond the first substrate 520, so as to install the capacitor 530 in the second mounting port 521.

[0091] Please see Figure 8 and Figure 9 In some embodiments, the display device 10 further includes a brightness sensor 600, which includes a second substrate 610 and a probe 620 disposed on the second substrate 610. The top of the fixing plate 100 is provided with a mounting portion 170, and the second substrate 610 is connected to the mounting portion 170.

[0092] Medical diagnostic equipment uses the DICOM (Digital Imaging and Communications in Medicine) standard, which ensures that medical images present consistent grayscale performance and visual perception on different display devices. Therefore, the display device 10 needs to be equipped with a brightness sensor 600 to dynamically adjust the display brightness according to changes in ambient brightness.

[0093] The brightness sensor 600 includes a second substrate 610 and a probe 620 disposed on the second substrate 610. The probe 620 is the core sensing element of the brightness sensor 600, and its function is to directly receive ambient light signals. A mounting portion 170 is provided on the top of the fixing plate 100, and the second substrate 610 is connected to the mounting portion 170, thereby realizing the mounting of the brightness sensor 600 on the fixing plate 100.

[0094] Optionally, the mounting portion 170 may include two mounting plates 171, which are respectively disposed on both sides of the second substrate 610. Each mounting plate 171 has a first mounting hole 172, and the second substrate 610 has second mounting holes 611 on both sides. Both the first mounting hole 172 and the second mounting hole 611 are screw holes, allowing the first mounting hole 172 to be connected to the corresponding second mounting hole 611 via screws, thus achieving fixed mounting of the brightness sensor 600. Since devices may be located in the connection area between the second substrate 610 and the mounting plate 171, a clearance space must be provided on the mounting plate 171 for clearance. Furthermore, an insulating sheet must be provided between the mounting plate 171 and the second substrate 610 to prevent short circuits caused by contact between devices on the second substrate 610 and the mounting plate 171.

[0095] In some embodiments, the display device 10 further includes a flexible member 630 having a mounting hole 631 through which a probe 620 passes. One side of the flexible member 630 contacts the second substrate 610, and the other side contacts the front frame.

[0096] The flexible component 630 has a mounting hole 631, through which the probe 620 passes. That is, the sides of the probe 620 are surrounded by the flexible component 630, so that only the light directly in front can enter the brightness sensor 600, thereby minimizing the incidence of scattered light from other directions, which would affect the monitoring of ambient light.

[0097] The flexible component 630 contacts the second substrate 610 on one side along the thickness direction Y and the front frame on the other side. This allows the flexible component 630 to limit the brightness sensor 600 along the thickness direction Y, reducing the wobbling of the brightness sensor 600 within the overall structure and improving the accuracy of ambient light monitoring. Optionally, the flexible component 630 can be foam.
