Description

Technical Field

[0001] The invention relates to a protection structure and a protection method, in particular to a liquid crystal display screen protection structure and a protection method, and belongs to the technical field of liquid crystal display screens. Background Art

[0002] Liquid crystal display is a flat display device that uses liquid crystal technology to display images. The working principle of liquid crystal display is based on the liquid crystal molecules changing their arrangement direction under the action of an electric field, thereby regulating the transmittance. Images are formed by irradiation from a backlight source (such as an LED or fluorescent lamp). Liquid crystal display has the characteristics of high resolution and high pixel density, and can present delicate and clear images. Compared with traditional cathode ray tube displays, liquid crystal display is thinner and lighter, and consumes less power. Through the combination of RGB primary colors and electronic control, liquid crystal display can achieve high-quality, rich color display effects. Liquid crystal display is widely used in various electronic products such as computers, televisions, mobile phones, tablets, and car displays.

[0003] The existing LCD screens do not have additional protective measures during transportation. During transportation, the LCD screens are easily bumped, which may cause damage to the LCD screens.

[0004] A known Chinese public authorized patent (publication number: CN217262064U) discloses a liquid crystal display screen protection structure, which can buffer or even eliminate the lateral vibration generated during the transportation or handling of the display screen by providing a protection platform, a spring cylinder, a protection plate and a suction cup, thereby ensuring that the structure of the display screen is not damaged;

[0005] The protection of the liquid crystal display screen is achieved by setting up a protective structure. However, the corners of the liquid crystal display screen often become high-incidence areas of collision and damage due to its structural characteristics and force mode. There is a lack of key protection for the corners of the liquid crystal display screen. Therefore, during handling or transportation, even if the overall protective structure can absorb most of the vibration energy, the corners will still be damaged due to excessive local force, resulting in poor protection effect. Moreover, the overall volume of the protective structure is large, which is inconvenient to handle or transport. Therefore, a liquid crystal display screen protective structure and a protection method are proposed. Summary of the invention

Therefore, during handling or transportation, even if the overall protective structure can absorb most of the vibration energy, the corners will still be damaged due to excessive local force, resulting in poor protection. In addition, the overall volume of the protective structure is large, which is inconvenient to handle or transport.

[0062] Step 2: Use the other two protective frames to buckle upside down on the LCD screen, connect the plug with the slot, and use bolts to fix the protective frames;

[0063] Step 3: Insert the pins on the connecting plate into the sockets, and the two protective components are installed;

[0068] Embodiment 3

[0069] like Fig.10 As shown, based on the technical solution of embodiment 1, a liquid crystal display screen protection structure also includes an intelligent monitoring device, wherein the intelligent monitoring device includes an acceleration sensor, a microcontroller, an alarm module and a power management module, and high-precision acceleration sensors are installed at the four corners of the first protection component 101 to monitor the acceleration changes of the display screen during transportation and handling in real time. The acceleration sensor is connected to the microcontroller, and the detected data is transmitted to the microcontroller for analysis and processing. The microcontroller is installed inside the first protection component 101; the protection frame 11 is made of high-strength and lightweight carbon fiber composite material, which not only ensures sufficient strength to resist external force impact, but also reduces the overall weight for easy handling.

[0070] A low-power, high-performance microcontroller is selected as the core of the intelligent monitoring system. The microcontroller receives the data from the acceleration sensor and performs real-time analysis and judgment.

[0071] Different acceleration thresholds are set in the microcontroller. When the detected acceleration exceeds the threshold, the microcontroller determines that the display screen may have been subjected to a large external force impact and immediately triggers the alarm system.

[0072] The alarm module includes a sound alarm and a light alarm. When the microcontroller detects an abnormal situation, the sound alarm is triggered to emit a loud alarm sound, and the LED warning light on the protective frame is lit to remind the user to take timely measures.

[0073] The alarm module can be connected to the user's mobile phone or other mobile devices through the wireless communication module. When an abnormal situation occurs, a push notification is sent to the user so that the user can understand the status of the display screen in time;

[0074] The power management module is powered by a built-in lithium battery. In order to extend the battery life, a low-power design is adopted. When not in use, the intelligent monitoring device enters a dormant state. When it detects that the display starts to move, it automatically wakes up and starts monitoring.

[0075] A charging interface is provided on the protective frame 11 to facilitate users to charge the lithium battery.

[0076] Specifically, install the protective structure:

[0077] Place the LCD screen inside the protective frame, making sure the soft rubber pads between the screen and the protective frame fit tightly.

[0078] Cover the front and back of the display with the protective net, and connect it to the protective frame through hooks.

[0079] Connect the four protective frames together through the magnetic interface to form a complete protective structure.

[0080] Start the intelligent monitoring device:

[0081] Press the start button on the guard frame to start the intelligent monitoring device. The microcontroller performs a self-test to ensure that the acceleration sensor and alarm module are working properly.

[0082] Users can view the status and parameter settings of the intelligent monitoring device through the mobile phone APP or the display screen on the protective frame.

[0083] Transport and handling:

[0084] During transportation and handling, the intelligent monitoring device monitors the stress of the display screen in real time. If an abnormality is detected, the alarm module immediately sounds an alarm to remind the user to take action.

[0085] Depending on the type and severity of the alarm, the user can decide whether to immediately check the status of the display or take other emergency measures.

[0086] Removal of protective structures:

[0087] When the display screen reaches its destination, press the disassembly button on the protective frame to disconnect the magnetic interface and remove the protective frame and protective net.

[0088] Turn off the smart monitoring device and keep it in a safe place for next use.

[0089] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
