[0042] As described in the background, the display device is a device capable of converting an electrical signal into visual information. In the related art, the display device includes a display body and a control member (such as a control circuit board), and the control member is usually fixedly installed inside the lower profile of the display body. However, the above assembly method causes the width of the lower profile to be unable to be reduced, so that the display body cannot realize an ultra-narrow frame design.

[0043] Reference Figures 1 to 5In order to solve the above problems, according to one aspect of the present application, the embodiment of the present application provides a display device, the display device comprising a display body 100, a mounting box 200 and a control piece 300, wherein the display body 100 has a back plate 110; the mounting box 200 is arranged on the back plate 110 and can slide along a preset direction; the mounting box 200 is provided with an opening 220 on a surface close to the back plate 110, the opening 220 is in communication with the inside of the mounting box 200; the control piece 300 is arranged in the mounting box 200; one of the mounting box 200 and the display body 100 is provided with a connecting male head 120, and the other is provided with a connecting female head 210 which is detachably connected with the connecting male head 120, and the control piece 300 is electrically connected with the display body 100 through plug connection of the connecting male head 120 and the connecting female head 210.

[0044] In the embodiment of the present application, the display device is an LED display screen (LED is the English full name of Light Emitting Diode, and the Chinese name is Light Emitting Diode), and in other embodiments, the display device can also be a liquid crystal display screen, an organic light emitting diode display screen or a plasma display screen. The display body 100 is the main structure for displaying visual information. The mounting box 200 can slide on the back plate 110 by using the matched guide rail and guide strip.

[0045] The preset direction is parallel to the length direction of the display body 100, in this case, the mounting box 200 can slide out from the right side edge or the left side edge of the display body 100; when the mounting box 200 is in the hidden position, the display body 100 covers the mounting box 200, so as to reduce the overall length of the display device and improve the aesthetics of the display device. In other embodiments, the preset direction can also be parallel to the width direction of the display body 100, in this case, the mounting box 200 can slide out from the upper side edge or the lower side edge of the display body 100. The control piece 300 is a control circuit board and is fixedly installed in the mounting box 200 by using connecting screws; in other embodiments, the control piece 300 can also be fixedly installed in the mounting box 200 by using welding, gluing or clamping.

[0046] In one aspect, the mounting box 200 and the control piece 300 used in combination in the present application abandon the mode of fixing the control piece 300 in the inside of the lower profile of the display body 100 in the related art, so that when the display body 100 and the control piece 300 are assembled, the position of the mounting box 200 can be adjusted according to actual needs, the control piece 300 does not occupy the space in the inside of the lower profile, the width of the lower profile is effectively reduced, the ultra-narrow frame design is realized, and the screen ratio and the visual effect of the display device are improved.

[0047] In another aspect, when the control member 300 needs to be maintained or replaced due to failure, the control member 300 is electrically connected to the display body 100 through the plug connection of the connection male head 120 and the connection female head 210. When the control member 300 needs to be maintained or replaced due to failure, the connection male head 120 and the connection female head 210 are first separated, so that the wire connected to the control member 300 on the display body 100 does not need to be moved together with the installation box 200. This operation measure not only effectively protects the wire, but also facilitates the smooth sliding of the installation box 200. Then, the installation box 200 is slid out and passed through the opening 220 to maintain the control member 300, avoiding the need to remove the entire installation box 200 from the display body 100, greatly reducing the difficulty and workload of maintenance.

[0048] In another aspect, the plug connection of the connection male head 120 and the connection female head 210 can ensure stable and reliable electrical connection between the control member 300 and the display body 100, avoiding problems such as loose connection or poor contact caused by external vibration, collision and other factors, and ensuring normal operation of the display device.

[0049] Referring to Figures 1 to 5 In an embodiment, the connection male head 120 is provided on the display body 100, and the connection female head 210 is provided on the installation box 200.

[0050] In this embodiment, the number of connection male heads 120 is multiple, and the multiple connection male heads 120 are arranged at intervals. The number of connection female heads 210 is the same as the number of connection male heads 120, and the multiple connection female heads 210 are arranged on the side of the installation box 200 and correspond to the multiple connection male heads 120 one by one. In other embodiments, the connection male head 120 can also be provided on the installation box 200, and the connection female head 210 is provided on the display body 100.

[0051] On the one hand, during the installation and use of the installation box 200, if the connection male head 120 is provided on the installation box 200, the connection line may be swung and pulled to a large extent with the movement of the installation box 200, thereby easily causing problems such as line fatigue and damage. By providing the connection male head 120 on the display body 100, the line is relatively fixed, which can effectively reduce the risk caused by the pulling of the line due to the movement of the installation box 200, thereby better protecting the line.

[0052] On the other hand, by providing the connection male head 120 on the display body 100, the position is relatively fixed and more easily observed, and the operator can more conveniently align and plug the connection female head 210 on the installation box 200 with the connection male head 120, thereby reducing the risk of prolonged assembly time or damage to the connection male head 120 and the connection female head 210 caused by difficult alignment.

[0058] On the other hand, the power input interface 400 provides stable power for the sending card 440, the network port direct insertion board 450, and other components through the adapter 420 and the power adapter board 430. This multi-stage power conversion and distribution design can effectively filter the noise and interference signals in the power supply, ensure that each component obtains stable and pure power supply, reduce equipment failures caused by power fluctuations, and improve the overall stability and reliability of the display device. At the same time, the electrical connection design between the sending card 440 and the network port direct insertion board 450 and between the network port direct insertion board 450 and the connection female head 210 ensures efficient and stable transmission of signals between components; through such close electrical connection and reasonable signal transmission path planning, signal attenuation and interference are reduced, the quality and transmission speed of the display signal are improved, thereby ensuring the clarity and smoothness of the display effect.

[0059] Referring toFigures 1 to 5 In an embodiment, the display device further comprises an OPS computer 470 and an OPS computer daughter card 480, and the mounting box 200 is provided with a limiting space communicating with the opening 220 on the side of the mounting box 200, the OPS computer 470 is arranged in the limiting space and is electrically connected to the control element 300 through the OPS computer daughter card 480.

[0060] In the embodiment, the limiting space is formed by inwardly bending the side plate of the mounting box 200 towards the inside of the mounting box 200.
