To solve the technical problems in the background art, embodiments of the present application provide a SIM card with an electrochromic film assembly, where the SIM card is applied to a terminal, as shown in fig. 1, and in one example, the terminal 100 is a smart phone. The terminal 100 has a processor 110, a SIM card holder 120, a SIM card 130, and an electrochromic film assembly 140.

In other examples, the terminal may also be other mobile terminals (e.g., tablet computers), wearable devices (e.g., smart watches, sports bracelets, smart glasses), smart car-mounted devices, etc. having 4G or 5G communication capabilities.

The processor 101 serves as a central processing unit of the terminal 100 and is configured to be connected to the SIM card holder 120, the SIM card holder 120 is configured to be connected to the SIM card 130 and supply power to the SIM card 130, and the electrochromic film assembly 140 is connected to the SIM card 130 and displays different colors according to different voltages.

The abnormal problems of a plurality of SIM cards of the existing terminal can be confirmed only by checking for many times by research personnel or users, but the SIM cards and the SIM card holders are easily abraded by many times of plugging and unplugging detection, and further certain damage is caused to detection equipment of the terminal.

In order to solve the above problem, embodiments of the present application provide a SIM card with an electrochromic film assembly. The SIM card is called a Subscriber Identity Module (SIM), and is a smart card mainly used for storing Subscriber Identity data, short message data, and phone numbers. The terminal is internally provided with an SIM card support corresponding to the SIM card, and the SIM card support is provided with chip contacts corresponding to the SIM card one by one. After the mobile phone or other mobile terminals are connected with the SIM card through the SIM card holder, the information of the SIM card is read, the relevant authentication is carried out, and after the information is passed, the wireless communication is carried out under the 3GPP/3GPP2 network.

The electrochromic film assembly is a material with electrochromic performance, and the electrochromic film assembly is a phenomenon that the optical properties (reflectivity, transmittance, absorptivity and the like) of the material generate stable and reversible color change under the action of an external electric field, and the electrochromic film assembly shows reversible change of color and transparency in appearance.

As shown in fig. 2, in a specific embodiment, the SIM card with electrochromic film assembly includes a SIM card 130, and an electrochromic film assembly 140 and a voltage dropping circuit 150 disposed on the SIM card 130. The SIM card 130 is provided with a power pin VCC131 and a ground pin GND132, the power pin VCC131 is used for being connected with a power output end of the SIM card holder 120, and the ground pin GND132 is used for being connected with a ground end of the SIM card holder 120. The voltage input terminal of the voltage dropping circuit 150 is connected to the power supply pin VCC131, and the voltage output terminal of the voltage dropping circuit 150 is connected to the electrochromic film assembly 140.

After the SIM card 130 contacts the SIM card holder 120, the pins on the SIM card 130 correspond to the pins on the SIM card holder 120 one to one, and if the SIM card 130 is normally connected to the SIM card holder 120, the power pin VCC132 of the SIM card 130 is at a normal voltage. If the SIM card 130 is abnormally connected to the SIM card holder 120, the power pin VCC132 of the SIM card 130 is at an overvoltage voltage or a low voltage. If the SIM card 130 is not connected to the SIM card holder 120, the power pin VCC132 of the SIM card is no voltage. The electrochromic film assembly displays different colors according to the voltage passing through the power pin VCC132 of the voltage dropping circuit 150, so that a developer can quickly determine the connection state of the SIM card 130 according to the colors.

In a specific embodiment, the voltage output terminal of the voltage dropping circuit 150 is connected to the power input terminal of the electrochromic film plate 142, and the power output terminal of the electrochromic film plate 142 is connected to the power input terminal of the electrochromic film element 141.

The color change of the electrochromic film element 141 can be quickly seen by the developer. Preferably, the electrochromic film element 141 is circular so as to be distinguished from the SIM card, and a developer can accurately determine the position of the electrochromic film element 141. In other embodiments, the electrochromic film element 141 may also change shape as desired.

In a specific embodiment, the electrochromic film plate 142 is configured to control the electrochromic film element 141 to display a first color when the power supply pin VCC131 is at a normal voltage. The electrochromic film plate 142 is configured to control the electrochromic film element 141 to display the second color when the power supply pin VCC131 is an overvoltage. The electrochromic film plate 142 is configured to control the electrochromic film element 141 to display the third color when the power supply pin VCC131 is a low voltage. The electrochromic film plate 142 is configured to control the electrochromic film element 141 to display a fourth color when the power supply pin VCC131 is not energized.

Wherein, the first color can be set to green to prompt the user that the current SIM card is connected normally. The second color can be set to be red so as to prompt the user that the SIM card is connected with overvoltage currently; the third color may be set to yellow to prompt the user that the SIM card is currently in low voltage connection; the fourth color may be set to the original color, which may be gray or transparent to indicate to the user that the SIM card is not currently connected.
