[0002] In recent years, with the continuous improvement of personal computer performance, personalization and aesthetic design have become important purchasing factors for desktop computers, especially gaming PCs and creative workstations. Computer cases with transparent side panels have emerged, allowing users to directly display the intricate internal hardware components such as graphics cards, CPU coolers, and memory modules. These components come with rich RGB lighting effects, satisfying the demand for personalized display.

[0003] To showcase internal hardware and RGB lighting effects, most transparent PC case side panels on the market are currently made of fixed transparent materials such as acrylic or tempered glass. Their transparency is fixed, resulting in complete transparency. This can easily lead to the following drawbacks with transparent side panels: 1. Inability to balance privacy and display: When the internal cables of the chassis are messy, the transparent side panel will expose the flaws and affect the aesthetics. Users can only choose to replace it with an opaque side panel, and there is no dynamic adjustment.

[0004] 2. Light pollution: Most computer cases have lighting effects for components such as case fans and graphics cards. Excessive and dazzling lights may interfere with vision and distract attention during gaming or work, and may also cause eye discomfort and affect eyesight. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0022] In specific embodiments of this utility model, such as Figure 1 As shown, a smart side panel for a computer chassis based on polymer-dispersed liquid crystal dimming is provided. It includes a side panel body 1, which is made of transparent acrylic sheet or tempered glass, making it completely transparent and visible. A polymer-dispersed liquid crystal film layer 2 is tightly adhered to the outer surface of the side panel body 1. The size and specifications of the polymer-dispersed liquid crystal film layer 2 are consistent with the side panel body 1, allowing it to completely cover the outer surface of the side panel body 1. An electrode lead 3 is provided on the left and right sides of the polymer-dispersed liquid crystal film layer 2, with the other ends of the two electrode leads 3 approaching each other along the periphery of the polymer-dispersed liquid crystal film layer 2. The other ends of the two electrode leads 3 are connected to a 2P connector 4. The male end of the 2P connector 4 is connected to the other end of the two electrode leads 3, and the female end of the 2P connector 4 is electrically connected to the positive and negative outputs of a control drive module 5, providing the high-voltage AC power required for the transparency change of the polymer-dispersed liquid crystal film layer 2. The high-voltage output of the control drive module 5 is encapsulated in the insulating housing of the female 2P connector 4, enabling safe insertion and removal and avoiding the risk of electric shock and short circuit during installation and use, thus ensuring high reliability.

[0023] Reference Figure 2 The input terminal of the control drive module is connected to a USB power supply interface 6, and the input terminal of the USB power supply interface 6 is connected to the USB power supply of the computer case. The input terminal of the control drive module 5 is connected to the output terminal of the USB power supply interface 6 to provide low-voltage DC power to the control drive module. In this specific embodiment of the invention, the low-voltage DC power is preferably +5V. The intelligent side panel of the computer case of this invention cleverly utilizes the computer case's own USB port for power, eliminating the need for a complex external power supply. It is plug-and-play, greatly improving installation convenience and overall aesthetics.

[0024] Reference Figure 2 The control drive module 5 includes a boost inverter unit, a main control unit, and a wireless communication unit, wherein: The input of the wireless communication unit establishes a communication connection with the output of the controller's wireless transmission module to receive state switching commands issued by the user through the controller and convert them into corresponding state switching signals; the output of the wireless communication unit is connected to the input of the main control unit to transmit the state switching signals to the main control unit.

[0025] Preferably, the state switching instruction is to switch the transparency state of the polymer-dispersed liquid crystal film layer. The transparency states of the polymer-dispersed liquid crystal film layer, in ascending order, include a blurred state, a first blurred state, a second blurred state, a third blurred state, and a clear state.

[0026] The main control unit converts the state switching signal into a corresponding state control signal, which is an output voltage signal with variable amplitude. In a specific embodiment of this invention, different transparent states correspond to different voltage signals with different amplitudes. Specifically, the blurred state corresponds to an output voltage signal of 0V; the first blurred state corresponds to an output voltage signal of 2.4V; the second blurred state corresponds to an output voltage signal of 2.7V; the third blurred state corresponds to an output voltage signal of 3.0V; and the clear state corresponds to an output voltage signal of 3.3V.

[0027] The output of the main control unit is connected to the reference voltage terminal of the boost inverter unit, and the output voltage signal is sent to the boost inverter unit as a feedback signal. The boost inverter unit uses the output voltage signal as a reference to convert the +5V low-voltage DC power provided by the USB power interface into high-voltage AC power, and transmits the high-voltage AC power to the polymer dispersed liquid crystal film layer through the 2P connector 4 and the two electrode leads 3, causing a change in the transparency of the polymer dispersed liquid crystal film layer.

[0028] In this specific embodiment of the invention, when the output voltage signal is 0V, the high-voltage AC output is 0V, which does not reach the threshold voltage, and the transparency of the polymer-dispersed liquid crystal film is in a blurred state. When the output voltage signal is 2.4V, the high-voltage AC output is 65V, which reaches the threshold voltage but does not reach the saturation voltage, and the transparency of the polymer-dispersed liquid crystal film is in a first blurred state. When the output voltage signal is 2.7V, the high-voltage AC output is 75V, which reaches the threshold voltage but does not reach the saturation voltage, and the transparency of the polymer-dispersed liquid crystal film is in a second blurred state. When the output voltage signal is 3.0V, the high-voltage AC output is 85V, which reaches the threshold voltage but does not reach the saturation voltage, and the transparency of the polymer-dispersed liquid crystal film is in a third blurred state. When the output voltage signal is 3.3V, the high-voltage AC output is 95V, which reaches the saturation voltage, and the transparency of the polymer-dispersed liquid crystal film is in a clear state.

[0029] Preferably, the polymer-dispersed liquid crystal film layer and the electrode leads are connected by conductive silver paste, forming a path with extremely low resistance between the polymer-dispersed liquid crystal film layer and the electrode leads. This ensures that the high-voltage AC power is applied efficiently and uniformly to the conductive layer of the entire PDLC film layer, avoiding local voltage drops and thus ensuring uniform dimming effect.

[0030] This utility model discloses a smart side panel for a computer chassis based on polymer-dispersed liquid crystal dimming, the working process of which is as follows: 1. Users input state switching commands via controller buttons.

[0031] 2. After receiving the state switching command, the wireless communication unit converts it into a corresponding state switching signal and transmits it to the main control unit.

[0032] 3. The main control unit converts the state switching signal into a corresponding state control signal and inputs it to the reference voltage terminal of the boost inverter unit.

[0033] 4. The boost inverter unit uses the output voltage signal as a reference to convert the +5V low-voltage DC power supplied by the USB power interface into high-voltage AC power.

[0034] 5. When the polymer-dispersed liquid crystal film receives high-voltage alternating current, it causes a change in the transparency of the polymer-dispersed liquid crystal film.

[0035] In summary, this invention achieves intelligent variable transparency of the computer case side panel by attaching a polymer-dispersed liquid crystal film layer to the side panel and establishing signal communication between the wireless communication module and the control drive module. This control module generates high-voltage alternating current to change the transparency of the polymer-dispersed liquid crystal film layer. Users can easily switch between transparent and blurred states of the computer case side panel using a button on the controller, perfectly balancing the needs of hardware display and privacy.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
