Description

Technical Field

[0001] This utility model relates to the technical field of LED displays, and in particular to an LED display that integrates touch and display. Background Technology

[0002] An integrated touch LED display is an LED display that integrates the backlight module directly onto the PCB board. It also integrates touch functionality, allowing the display to not only show images but also enable interactive operations via touch. Large LED displays are typically installed on or near walls, which limits heat dissipation.

[0003] Chinese Patent Publication No. CN220856008U, published on April 26, 2024, discloses a direct-touch integrated LED display module. The module includes an LED display panel, a fixing frame, a sealing plate, and a mounting cover. An integrated touchscreen is mounted on the LED display panel, which is composed of arranged LED chips and features high brightness, high contrast, and a wide viewing angle. The touchscreen is made of a transparent conductive material and can sense user touch operations. By directly covering the LED display panel with the touchscreen, an integrated display effect is achieved. The touch sensor is integrated into the LED display panel, enabling direct touch interaction. Users can perform gesture operations on the touchscreen panel to control and switch displayed content. The sealing plate is inserted into the fixing frame and connected to the fastener via hooks, facilitating disassembly, assembly, inspection, and maintenance. Through integrated design, optimized structure, and integrated touch sensor, the display effect of the LED display module is effectively improved. The drawback of this invention is that heat dissipation is not very good. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of insufficient heat dissipation in the existing technology and provide an integrated touch and display LED display screen with better heat dissipation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An LED display screen integrating touch and display functions, comprising: The housing is connected front and rear and has baffles around the front end; An LED light board is placed inside a mounting housing. A PCB board is fixed on the rear end face of the LED light board. The PCB board has a touch sensing module and a display driver module. The display diaphragm is placed between the mounting housing baffle and the LED light board and is connected to the LED light board; The back plate is placed behind the PCB board and inside the mounting housing. The back plate is fixedly connected around its perimeter by screws passing through the outer side of the mounting housing. The back plate is provided with several ventilation strips, which are arranged in pairs and run in a left-right direction. The ventilation strips are fixedly connected to the inner side of the back plate, and the other end of the ventilation strips contacts the back of the PCB board. Several ventilation holes are evenly distributed on the left and right sides of the mounting housing and are connected to the interior of the mounting housing. The positions of the ventilation holes on the left and right sides are staggered. A group of ventilation strips corresponds to one ventilation hole. The two ventilation strips in a group are placed at the upper and lower ends of the corresponding ventilation hole, respectively. There is a gap between the end of the ventilation strip far from the ventilation hole and the inner side of the mounting housing.

[0006] During assembly, the display film is installed on the LED light board with the PCB board, and both are placed inside the mounting housing, which is then sealed by the back plate. The ventilation strips hold the PCB board in place, and finally, the back plate is fixed to the mounting housing with screws. During use, the assembled LED display screen is installed in the appropriate position with the back plate as needed. When the machine starts running, outside air enters the mounting housing through the side ventilation holes. The ventilation channel formed by the two ventilation strips guides the internal heat to the other side and out through the ventilation holes on the other side. This forms a heat dissipation channel that circulates back and forth and dissipates heat, achieving better heat dissipation.

[0007] Preferably, the backplate includes a base material and a filler, with the filler placed inside and connected to the base material. The base material and the filler together form a heat-dissipating plastic, allowing the backplate itself to act as a heat sink to accelerate heat dissipation.

[0008] Preferably, the outer surface of the mounting housing is provided with several baffles, each corresponding to a ventilation hole. The baffles have an arc-shaped cross-section and are positioned above the ventilation holes. The baffles are fixedly connected to the mounting housing. The baffles prevent water and other liquids from entering the mounting housing, reducing damage to electronic components such as the PCB board.

[0009] Preferably, the distance between the ends of the two ventilation strips in a group that are closest to the ventilation holes is greater than the width of the ventilation holes, while the distance between the other ends of the two ventilation strips in a group is less than the width of the ventilation holes. The gradually decreasing distance between the two ventilation strips allows the ventilation duct to form a funnel shape, increasing airflow and accelerating heat dissipation.

[0010] Preferably, a dust filter is provided inside the ventilation hole, and the side of the dust filter is fixedly connected to the inner side of the ventilation hole. The dust filter can reduce the amount of dust entering the mounting housing and reduce damage to electronic components such as PCB boards.

[0011] Preferably, a plurality of hanging rings are evenly distributed on the outer surface of the substrate material, and the hanging rings are fixedly connected to the outer surface of the substrate material. The hanging rings facilitate wall mounting of the LED display screen.

[0012] Preferably, the hanging ring has a cover on the end face of the material opposite to the base material. The cover is fixedly connected to the hanging ring. The cover has a hanging hole, the lower part of which is circular and the upper part is square. The lower diameter of the hanging hole is larger than the upper width. The hanging hole on the cover allows for a more secure fixation with a hook.

[0013] The beneficial effects of this utility model are: better heat dissipation; the base material and filler form a heat-dissipating plastic, allowing the back plate itself to act as a heat dissipation component to accelerate heat dissipation; the baffle prevents water and other liquids from entering the mounting housing, reducing damage to electronic components such as PCB boards; the distance between the two ventilation strips gradually decreases, making the ventilation duct funnel-shaped to increase airflow and accelerate heat dissipation; the dust filter reduces dust from entering the mounting housing, reducing damage to electronic components such as PCB boards; the hanging ring facilitates wall mounting of the LED display screen; and the hanging holes on the cover allow for more secure fixing with hooks.

[0017] like Figures 1 to 4In one embodiment, an integrated touch and display LED display screen includes: a mounting housing 1 with front and rear connections and a baffle around its front end; an LED light board 2 placed inside the mounting housing 1, with a PCB board 5 fixed to the rear end face of the LED light board 2, the PCB board 5 having a touch sensing module and a display driving module; a display film 3 placed between the baffle of the mounting housing 1 and the LED light board 2 and connected to the LED light board 2; and a back plate 4 placed behind the PCB board 5 and inside the mounting housing 1, the back plate 4 being fixedly connected around its perimeter by screws passing through the outer surface of the mounting housing 1, and the back plate 4 having several through-slots. The ventilation strips 7 are arranged in pairs and run in a left-right direction. The ventilation strips 7 are fixedly connected to the inner side of the back plate 4, and the other end of the ventilation strips 7 is in contact with the back of the PCB board 5. Several ventilation holes 6 are evenly distributed on the left and right sides of the mounting housing 1 and are connected to the interior of the mounting housing 1. The positions of the upper ventilation holes 6 on the left and the upper ventilation holes 6 on the right are staggered. One set of ventilation strips 7 corresponds to one ventilation hole 6. The two ventilation strips 7 in a set are placed at the upper and lower ends of the corresponding ventilation hole 6, respectively. There is a gap between the end of the ventilation strip 7 that is far from the ventilation hole 6 and the inner side of the mounting housing 1.

[0018] like Figure 4 As shown, the back plate 4 includes a matrix material 8 and a filler 9, with the filler 9 filling the interior of the matrix material 8.

[0019] like Figure 1 and Figure 5 As shown, there are several flanges 10 on the outer side of the mounting housing 1, which correspond one-to-one with the ventilation holes 6. The cross-sectional shape of the flanges 10 is arc-shaped. The flanges 10 are placed above the ventilation holes 6 and are fixedly connected to the mounting housing 1.

[0020] like Figure 3 As shown, the distance between the two ventilation strips 7 in a group and the end of the ventilation hole 6 that are closest to each other is greater than the width of the ventilation hole 6, and the distance between the other ends of the two ventilation strips 7 in a group is less than the width of the ventilation hole 6.

[0021] like Figure 5 As shown, a dustproof net 11 is installed inside the ventilation hole 6, and the side of the dustproof net 11 is fixedly connected to the inner side of the ventilation hole 6.

[0022] like Figure 1 and Figure 2 As shown, several hanging rings 12 are evenly distributed on the outer surface of the substrate material 8, and the hanging rings 12 are fixedly connected to the outer surface of the substrate material 8.

[0023] like Figure 1As shown, a cover 13 is fixed on the end face of the hanging ring 12 far from the base material 8. The cover 13 has a hanging hole 14. The lower part of the hanging hole 14 is circular and the upper part is square. The lower diameter of the hanging hole 14 is larger than the upper width of the hanging hole 14.

[0024] During assembly, a display film 3 is installed on the LED light board 2 with PCB board 5, and both are placed inside the mounting housing 1, where a back plate 4 seals them. A ventilation strip 7 holds the PCB board 5 in place. Finally, screws are used to secure the back plate 4 to the mounting housing 1. The back plate 4 is made of a base material (such as PP, PC, etc.) filled with filler 9 (such as graphite, fibrous high thermal conductivity carbon powder, etc.) to accelerate heat dissipation. The overall LED board and PCB board components incorporate existing technologies such as touch modules and display driver modules, which will not be elaborated upon here. During use, the assembled LED light board is connected as needed. The ED display screen is mounted in a suitable position using the hanging ring 12 on the back plate 4. The hook or nail passes through the hanging hole 14 on the cover 13 to hook the hanging ring 12, so that it will not fall off at will. When the machine starts running, the outside air will enter the mounting housing 1 through the side ventilation hole 6. The ventilation channel composed of two ventilation strips 7 guides the internal heat to the other side and flows out through the ventilation hole 6 on the other side. This forms a heat dissipation channel for back-and-forth circulation and heat dissipation. Rainwater and other liquids are blocked by the baffle 10, and dust and other solid impurities are blocked by the dust screen 11, which greatly reduces the damage to electronic components and achieves better heat dissipation.
