[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When in use, the hydraulic rod is started to extend the two movable rods and the two connecting rods at the same time, thereby pushing the LCD screen outward, which is convenient for disassembly and maintenance of the LCD screen in any position. There is no need to move other LCD screens during disassembly. The support spring is connected between the connecting plate and the reinforcing plate, which improves the stability and provides elastic support for the fixed frame on which the LCD screen is installed.

[0019] 2. When in use, the LCD screen can be installed by hanging the buckle inside the buckle at the corresponding position. The installation method is simple, fast and stable. The sound sensor is installed in the middle position inside the fixed bottom box to collect the surrounding sounds. The fixed bottom box is closed by the fixed bottom plate, and in front of it, the protective plate is installed on the inner wall of the connecting groove with screws, so the command sound issued by the user can pass through the sound-transmitting hole and be collected by the sound sensor.

The drive module controls the electrochromic layer in the electrochromic aluminum alloy frame to undergo chemical reaction or physical change according to the received electrical signal instruction, thereby achieving color change. After the electrochromic aluminum alloy frame receives the control signal from the drive module, the electrochromic material inside the color-changing execution module begins to change color and gradually adjusts to a color that matches the screen image. The real-time monitoring module monitors the actual color change of the frame in real time, and feeds back the monitoring results to the signal processing unit. The signal processing unit adjusts the electrical signal instruction in time according to the feedback information, and fine-tunes the color of the frame to ensure that it is completely consistent with the color of the screen image.

Multiple control module units and wiring of the LCD screen 201 are arranged inside the junction box 205. In addition, by The sound sensor 304 is installed in the middle position of the fixed bottom box 301, and can collect the surrounding sounds. The fixed bottom box 301 is closed by the fixed bottom plate 302, and in front of it, the protective plate 305 is installed on the inner wall of the connecting groove 303 by using screws, so that the command sound issued by the user can pass through the sound-permeable hole 306 and be collected by the sound sensor 304. Through the built-in sound sensor 304, the user only needs to speak a voice command to control the LCD screen 201. When one of the LCD screens 201 fails and needs maintenance, the hydraulic rod 419 is started to extend it.
