[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the specific structure of a color-changing protective cover controlled by a communication terminal of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] It should be noted in advance that this application is based on the basic design of structural color, and different optical diffraction and reflection effects are formed by changing the internal crystal structure of the material, giving people different color and graphic sensory effects. The principle is inspired by the color change mechanism of chameleon or butterfly wings. The protective shell is designed with a specific multi-layer photonic crystal structure material, which can rotate the photonic crystal structure through the internal electric field bias, change the incident visible light and interact with the physical structure of the material crystal, selectively reflect and transmit light of different frequencies and wavelengths, so that the incident light produces similar multi-film interference and Bragg diffraction effects, forming a photon band gap. When the range of the photon band gap falls within the corresponding visible light range, light of a specific wavelength will not be able to pass through the optical crystal and form a reflection on the optical crystal. By changing the different crystal band gaps, visible light of different wavelengths can be reflected and enter the visual nerves of the human eye, so that the human body can perceive different light colors.

[0024] In addition, for photonic crystal materials, this application is to change the polarization characteristics of the medium inside the crystal by controlling the chip to output different level signals to the crystal material. The refractive index of the leather case crystal changes, which is called the electro-optical effect in physical properties. The refractive index (or inverse dielectric tensor ß) of the crystal is proportional to the external low-frequency electric field E (Ω).

[0025] It is theoretically proven that when a low-frequency electric field E (Ω) is applied, the photonic crystal will cause crystal displacement due to the change in the input electric field, causing the refractive index of the crystal to change accordingly, thereby reflecting wavelengths of different frequencies, realizing the physical properties of diffraction of different colors from the change in the electric field.

[0026] Please refer to the attached Figures 1 to 4 , is a schematic diagram illustrating a color-changing protective cover controlled by a communication terminal described in the present application; wherein Figure 1 This is the overall implementation module structure diagram; Figure 2 This is a schematic diagram of the composition of the color change control submodule described in this embodiment; Figure 3 is a schematic diagram of the layered structure of the color-changing protective cover; Figure 3 The circuit diagram for realizing the color change of the color change protective cover is shown below. Figures 1 to 4 The color-changing protective cover is described in detail.

[0027] The present embodiment relates to a communication terminal 1 and a color-changing protective cover 2, wherein the communication terminal 1 is used in conjunction with the color-changing protective cover 2; the color-changing protective cover 2 comprises a protective shell 20 and a color-changing module 30, wherein the color-changing module 30 is built into the protective shell 20 and forms an integral structure with the protective shell 20, and the color change of the color-changing protective cover 2 is intelligently controlled by the communication terminal 1; the communication terminal 1 sends a color change demand signal, and the color change module 30 receives the color change demand signal, and outputs a level signal corresponding to the corresponding color after decoding, and the color change module 30 changes color under the action of the level signal, and presents the corresponding target color through the protective shell 20.

[0028] Therefore, the communication terminal 1 can change the color of the protective shell 20 by sending a color change demand signal according to user needs and preferences, and the color change module 30 executes the color change instruction accordingly after receiving the signal. In actual operation, in this embodiment, it is achieved by generating an electric field corresponding to the target color to act on the protective shell 20.

[0029] Furthermore, in the present embodiment, the color change module 30 specifically includes a Bluetooth data receiving and decoding submodule 301, a color change control submodule 302, a thin film transistor layer 304 and an optical crystal layer 303; in terms of the connection structure, the Bluetooth data receiving and decoding submodule 301, the color change control submodule 302 and the thin film transistor layer 304 are electrically connected together, and are jointly coated with the optical crystal layer 303 in the protective shell cover 20, thereby forming an integrated structure with the protective shell cover 20.

[0030] As attached Figure 1 and 3 As shown, the protective shell 20 includes a transparent outer layer 201 and a shell inner layer 202 , the color changing module 30 is entirely located between the transparent outer layer 201 and the shell inner layer 202 , and the optical crystal layer 303 is disposed closely to the transparent outer layer 201 .

[0031] As for the functional implementation of the color-changing module 30, the Bluetooth data receiving and decoding submodule 301 is responsible for receiving the color-changing signal sent by the communication terminal 1, converting it into baseband data of the corresponding color after decoding, and then transmitting it to the color-changing control submodule 302; the color-changing control submodule 302 outputs signals of different levels to the thin-film transistor layer 304, and the thin-film transistor layer 304 generates an electric field to control the optical crystal layer 303; the optical crystal layer 303 is composed of a plurality of crystals evenly arranged, and under the action of the electric field generated by the thin-film transistor layer 304, the crystals reverse different structural angles and reflect polarized light of different wavelengths, thereby forming different colors, and then presenting the changed colors through the protective shell 20.

[0032] As can be seen from the above, under the action of an external electric field, the optical crystal layer 303 can achieve a change in the polarization characteristics of its internal medium, so that the refractive index of the optical crystal layer 303 changes and reflects wavelengths of different frequencies to present different colors or patterns, and the color change is presented by the transparent outer layer 201; in this embodiment, the surface layer of the color-changing protective cover 2 is set to the transparent outer layer 201, and it is also considered that the transparent outer layer 201 can achieve better color change presentation.

[0033] For further information, please refer to the attached Figures 1 to 4 In order to achieve uniform and effective color change of the optical crystal layer 303, an electric field of the same strength must act on the optical crystal layer 303. Therefore, in this embodiment, the color change control submodule 302 includes a color change control mainboard 3021, a control signal line 3022 and a power supply battery 3023; the color change control mainboard 3021, the control signal line 3022 and the power supply battery 3023 are connected together, and an electric field signal control IC is provided on the color change control mainboard 3021. The power supply battery 3023 provides the color change control mainboard 30 21, the electric field signal control IC generates a level signal corresponding to the target color selected by the user and outputs it through the control signal line 3022, so that the thin film transistor layer 304 generates a corresponding electric field effect; the control signal line 3022 is connected to the thin film transistor layer 304 in a row and column matrix data arrangement, and the control signal line 3022 and the thin film transistor layer 304 are evenly arranged close to the optical crystal layer 303; so as to achieve an electric field with the same and uniform intensity acting on the entire area of ​​the optical crystal layer 303, thereby producing a uniform and effective color change effect.

[0034] It is necessary to explain the specific arrangement of the control signal line 3022 and the thin film transistor layer 304. Figure 4 , the control signal line 3022 is electrically connected to the thin film transistor layer 304, the control signal line 3022 includes a row signal line and a column signal line, the row signal line and the column signal line are arranged vertically in a matrix manner and the intersection is a node, the thin film transistor layer 304 includes a thin film transistor, each of the nodes is provided with a thin film transistor 3041, and the thin film transistor 3041 generates an electric field under the joint action of the level signal of the row signal line and the column signal line. It can be seen that after the control signal line 3022 and the thin film transistor layer 304 are electrically connected in a matrix manner, they are together close to the optical crystal layer 303 and built into the protective shell 20.

[0035] In addition, it should be further explained that the Bluetooth data receiving and decoding submodule 301 includes a Bluetooth decoding IC, which is also arranged on the color change control mainboard 3021. The Bluetooth decoding IC receives and decodes the color change demand signal, generates baseband data corresponding to the target color, and transmits it to the color change control submodule 302.

[0036] Further, in this embodiment, please refer to the attached Figure 1 The communication terminal 1 also includes a color change demand sending module 10, which includes a color selection application software 101, a signal conversion submodule 102 and a signal sending submodule 103. The signal sending submodule 103 is a Bluetooth communication chip. After the user opens the color selection application software 101 and selects the target color, the signal conversion submodule 102 converts the target color into a corresponding data signal, and sends the color change demand signal through the Bluetooth communication chip 103.

[0037] It can be seen that when the user has a color change requirement for the color-changing protective cover 2, he first enters the color change requirement sending module 10, selects the color or pattern to be changed through the color selection module 101, the signal conversion submodule 102 converts the selected color or pattern into a data signal, and sends the color change requirement signal through the signal sending submodule 103.

[0038] In this embodiment, the color change control main board 3021 outputs a corresponding level signal, which is transmitted to the thin film crystal layer 304 through the control signal line 3022 to generate an electric field and act on the crystals in the optical crystal layer 303, thereby generating corresponding color change.

[0039] Please refer to the attached Figure 4, which is a circuit connection distribution diagram for realizing the color change of the optical crystal layer 303 in the color-changing protective cover 2 of the present application. It should be noted that, considering that the control signal line 3022 is connected to the thin film transistor layer 304 and is evenly arranged, the entire circuit is arranged in layers in this embodiment, namely, it includes an upper layer 100 and a lower layer 200; wherein, the control signal line 3022 and the thin film crystal layer 304 are connected together in a row-column matrix data arrangement as a single layer, namely, set as the upper layer 100; the Bluetooth signal decoding submodule 301 and the color change control submodule 302 are located between the upper layer 100 and the shell. The lower layer 200 is formed between the layers 203, that is, in terms of hardware structure, the lower layer 200 includes the color change control main board 3021 and the power supply battery 3023 electrically connected together; it also includes the electric field signal control IC arranged on the color change control main board 3021; ​​at the same time, the color change control main board 3021 of the lower layer 200 is connected to the control signal line 3022 of the upper layer 100, and then connected to the thin film crystal layer 304 through the control signal line 3022.

[0040] For the layered structure of the color-changing protective cover 2, please refer to the attached Figure 3 It is also important to explain that, from the outside to the inside, they are the transparent outer layer 201, the optical crystal layer 303, the upper layer 100, the lower layer 200, and the shell inner layer 202. The layered arrangement of the above embodiment can achieve a better color change effect of the optical crystal layer 303, and at the same time achieve a better presentation of the color change of the transparent outer layer 201.

[0041] As described above, the technical design idea of ​​the embodiment described in the present application is to utilize the principle that the optical crystal layer can produce different deflection angles under the action of electric fields of different intensities, and then refract light of different wavelengths to achieve color change. By establishing a communication connection between the communication terminal and the color-changing protective cover, when the communication terminal sends a color-changing demand signal, the color-changing protective cover can respond, use Bluetooth communication to receive the color-changing demand signal, and use a built-in control circuit to generate an electric field corresponding to the color selected by the user and act on the optical crystal layer to achieve the corresponding color change; thereby, a new technical solution is proposed, in which the user can change the color of the color-changing protective cover anytime and anywhere, and can change the color-changing protective cover to the desired color at will.

[0042] The embodiment of the present invention only lists one structural form of the color-changing protective cover controlled by a communication terminal. Obviously, the structural form and color-changing implementation method of the color-changing protective cover are not limited to the above embodiments. In the field of leather cases, protective shell cases, and structural design and color-changing design of their outer shells adapted to various communication terminals, as long as it involves the need to provide controllable and variable colors that are not limited to the use environment, the specific structure of the color-changing protective cover controlled by a communication terminal described in this application can be used as a reference for changes and expansions, and should all fall within the protection scope of this application.
