[0023] In existing technologies, most mainstream infrared frame solutions for display devices are made of aluminum extrusion profiles, filter strips, and internal and external corner structures. Among them, the infrared frame is usually made of aluminum extrusion profiles, which will cause a certain degree of deformation. This results in low efficiency when the circuit board is installed in the infrared frame, and it is also easy to cause damage to the components.

[0024] This utility model proposes a display device.

[0025] Please see Figures 1 to 3 As shown, in one embodiment of the present invention, the display device includes: a display module 100, a light filter 200, and a circuit board 300. The display module 100 has a display surface. The light filter 200 is arranged in a ring shape to form a touch space 210 on the inner side of the ring. The touch space 210 is arranged corresponding to the display surface. The light filter 200 has a light-transmitting portion 220 facing the touch space 210. The circuit board 300 is embedded in the light filter 200. The circuit board 300 is provided with an emitter 310 for emitting light and a receiver for receiving light. Light can penetrate the light-transmitting portion 220 to be directed towards the touch space 210 or towards the receiver.

[0026] It should be noted that the display device proposed in this utility model includes, but is not limited to, infrared touch commercial displays, infrared touch educational machines, and other display devices. In specific implementation, the display module 100 is used for display, and the circuit board 300 is equipped with a transmitter 310 and a receiver to achieve touch function through the emission and reception of light. Specifically, the transmitter 310 is an infrared light transmitter 310. Of course, the infrared light here is usually the invisible infrared band. It passes through the light-transmitting part 220 of the light filter 200 and shines towards the receiver in the touch space 210. When an object (such as a finger) touches the screen, it blocks part of the infrared light. The receiver detects the change in light intensity and thus determines the touch position.

[0027] The light filter 200 is arranged in a ring shape to form a touch space 210, and is correspondingly positioned to the display surface. The touch space 210 is located inside the space formed by the light filter 200, and touch functionality is achieved by touching the display surface through the touch space 210. The shape of the touch space 210 can be square, circular, or any other arbitrary shape, depending on the requirements of the display device. In this embodiment, the touch space 210 is formed by four light filters 200 surrounding it. The circuit board 300 is embedded in the light filter 200. The side portion of the light filter 200 between the top surface and the display surface forms a light-transmitting portion 220, ensuring that the light emitted by the emitter 310 can pass through the light-transmitting portion 220 and reach the touch space 210 to achieve touch control operation.

[0028] This utility model's technical solution employs a display module 100 to form a display surface, a transmitter 310 and a receiver mounted on a circuit board 300, and a light filter 200 to form a touch space 210. The touch space 210 is positioned corresponding to the display surface, enabling touch operation on the display surface. The light filter 200 has a light-transmitting portion 220 that allows light to pass through and reach the receiver, thus achieving touch control. Embedding the circuit board 300 within the light filter 200 avoids the impact of infrared frame deformation on the circuit board 300's installation efficiency compared to existing technologies.

[0029] In one embodiment, the filter 200 has a mounting cavity 230 inside, and the circuit board 300 is disposed within the mounting cavity 230. In a specific implementation, the filter 200 is elongated and hollow inside to form the mounting cavity 230. Openings are provided at both ends of the filter 200 to facilitate the installation of the circuit board 300 into the mounting cavity 230 through these openings. The edge of the circuit board 300 is connected to the inner wall of the mounting cavity 230, and the circuit board 300 is perpendicular to the display surface, allowing the transmitter 310 and receiver to emit light through the light-transmitting portion 220 of the filter 200.

[0030] Furthermore, the inner wall of the mounting cavity 230 is provided with a slot 240, and the edge of the circuit board 300 is engaged in the slot 240.

[0031] In this embodiment, reference Figure 1 and Figure 2 As shown, grooves are formed on the top and bottom walls of the mounting cavity 230, with the upper and lower grooves corresponding to each other, so that the top and bottom edges of the circuit board 300 can be engaged in the grooves and slidably installed into the mounting cavity 230 along the grooves. The slot 240 can be formed by a recess in the inner wall of the mounting cavity 230, or it can be formed by parallel protrusions on the inner wall of the mounting cavity 230 to engage the circuit board 300.

[0032] Continue to refer to Figure 1 As shown, in one embodiment, the inner wall of the mounting cavity 230 is provided with fixing strips 250, two adjacent fixing strips 250 are spaced apart, and the space between them forms a slot 240.

[0033] In the specific implementation process, the fixing strip 250 protrudes from the inner wall of the mounting cavity 230 and extends along the length of the filter strip. The two fixing strips 250 are arranged in parallel and spaced apart perpendicular to their extension direction, so that the space between the two fixing strips 250 forms a slot 240, which facilitates the installation of the circuit board 300 while ensuring the overall strength of the filter strip.

[0034] It should be noted that most of the mainstream infrared frame solutions on the market at present are made of aluminum extrusion profiles, filter strips and internal and external corner structures. The profiles need to be assembled, and there are internal and external corners. Adaptors are needed to connect the corners, which takes a long time to assemble and is prone to appearance problems such as seams and step differences.

[0035] In one embodiment, the display device further includes a front frame 400 and a bottom frame 500, which are connected end-to-end and arranged around the edge of the display module 100. A light filter 200 is connected to both the front frame 400 and the bottom frame 500, and the front frame 400 is integrally formed. Specifically, the front frame 400 is U-shaped, and the two ends of the bottom frame 500 are respectively locked to the two free ends of the front frame 400 by screws, so that both surround the outer periphery of the display module 100, facilitating the installation of the display module 100 and also protecting it. The integrally formed front frame 400 prevents the end of the front frame 400 away from the bottom frame 500 from forming a splicing corner, avoiding problems such as splicing gaps and unevenness.

[0036] This embodiment solves the problems of corner seams, difficult assembly, and low assembly efficiency by adopting a one-piece front frame 400. Furthermore, the unit cost is significantly reduced compared to existing corner infrared frames. In addition, the one-piece front frame 400 effectively reduces the number of assembly screws from 24 to 4, simplifying assembly and saving labor costs.

[0037] In one embodiment, the front frame 400 is provided with a fixing groove, the opening of the fixing groove facing the touch space 210, and the filter element 200 is snapped into the fixing groove.

[0038] In the specific implementation process, the front frame 400 adopts an aluminum extrusion profile or other profile with a slot on one side, the slot facing the display module 100, the light filter 200 is installed into the fixing groove through the slot, and the light-transmitting part 220 of the light filter 200 is located on one side of the slot.

[0039] In one embodiment, the display module 100 includes a back plate 110, and the front frame 400 is provided with a mounting base 410. The back plate 110 and the mounting base 410 are detachably connected. In specific implementation, the back plate 110 is fixedly connected to the front frame 400 so that the display module 100 is fixed to the front frame 400. It can be understood that the back plate 110 is also connected to the bottom frame 500. In this embodiment, the mounting base 410 is fixedly provided at the bottom of the front frame 400. The mounting base 410 is provided with threaded holes. The back plate 110 is installed on the front frame 400 by screws fastening it into the threaded holes. The back plate 110 and the bottom frame 500 are also fastened together by screws. In addition, a flange is provided on the bottom side of the front frame 400 opposite to the slot. The flange extends towards the back plate 110 to protect the edge of the back plate 110. The edge of the back plate 110 is bent and abuts against the flange of the front frame 400. The installation of the edge of the back plate 110 also improves the overall aesthetics.

[0040] In one embodiment, the display device further includes a touch glass 600, which is connected to the display module 100. The touch glass 600 has a touch surface, which is correspondingly disposed with the display surface.

[0041] In the specific implementation process, the touch glass 600 contacts the touch space 210, and the surface of the touch glass 600 facing the touch space 210 is the touch surface. Touch control is achieved by performing touch operations on the touch surface. In this embodiment, the touch glass 600 is made of tempered glass, which can protect the display screen of the display module 100 and extend the service life of the device.

[0042] The edge of the touch glass 600 contacts the light filter 200. The light filter 200 also includes a mounting part 260, which is connected to the light-transmitting part 220. The light-transmitting part 220 extends toward the display space. The mounting part 260 is bent to form a mounting groove. The edge of the touch glass 600 is located in the mounting groove and abuts against the inner wall of the mounting groove.

[0043] Specifically, the filter element 200 is disposed on one side of the light-transmitting part 220 and bends from the bottom of the light-transmitting part 220 toward the interior of the mounting cavity 230. In this way, a mounting groove is formed below the light-transmitting part 220. The side wall of the touch glass 600 abuts against the mounting groove. Furthermore, the surface of the touch glass 600 near the edge and facing the touch space 210 also abuts against the filter element 200 to avoid gaps between the two and ensure the overall sealing of the display device.

[0044] In one embodiment, the display module 100 includes a display element 120 and a connector 130. The display element 120 is disposed on the connector 130 and located on the side of the touch glass 600 away from the touch surface. The connector 130 is also used to support the touch glass 600.

[0045] In this embodiment, the display element 120 is used to display images, etc., and is located on one side of the touch glass 600, which also protects the display element 120. One end of the connector 130 contacts the touch glass 600, and the other end contacts the back plate 110 to support the touch glass 600. Additionally, the connector 130 is provided with a mounting platform for supporting and mounting the display element 120. In specific implementations, the connector 130 uses a plastic frame to support the display element 120 and the touch glass 600.
