[0003] However, during the conception and implementation of this application, the inventors discovered the following problems: In some solutions, a dot-matrix e-ink screen is used, and the etched glass in the e-ink screen component is a fixed rectangular size, which means that the e-ink screen can only be a few fixed specifications and cannot be made into irregular shapes, thus limiting the user's ability to customize the color-changing area; the etched glass in the dot-matrix e-ink screen component is relatively thick, which increases the overall thickness and weight of the device; the dot-matrix e-ink screen can only display based on photo projection, and its display resolution is limited, the projected image has obvious jagged edges, and the way the photo is mapped onto the e-ink screen requires continuous flickering for more than 10 seconds to finally form an image, which affects the user experience to some extent.

Although Figure 1 WiFi module 102 is shown, but it is understood that it is not a necessary component of a mobile terminal and can be omitted as needed without changing the nature of the invention.

[0035] The audio output unit 103 can convert audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into audio signals and output them as sound when the mobile terminal 100 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 103 can also provide audio output related to specific functions performed by the mobile terminal 100 (e.g., call signal receiving sound, message receiving sound, etc.).

The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage media) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0037] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors.

Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as touch screen, can collect touch operations on or near the user (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110.

Furthermore, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0043] The processor 110 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 110 may include one or more processing units; optionally, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication.

[0044] The mobile terminal 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Yes, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0045] although Figure 1 As not shown, the mobile terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0046] Based on the above-described mobile terminal hardware structure, various embodiments of this application are proposed.

[0047] like Figures 2 to 3 As shown, the first embodiment of this application provides a housing assembly, which includes a back plate layer 5 and a color-changing structure stacked together. The back plate layer 5 has at least two receiving portions, and the color-changing structure includes color-changing regions respectively received in the at least two receiving portions. An electronic ink layer 4 is provided in the color-changing regions, and the electronic ink layer 4 in the at least two color-changing regions is used to change color independently of each other under the control of an electrical signal.

[0048] The housing assembly may include a first protective layer 1, a light-transmitting layer 2, and a color-changing structure, wherein the color-changing structure may include an electronic ink layer 4. The first protective layer 1 is used to protect the electronic ink layer 4 and improve its surface strength, and the light-transmitting layer 2 is used to enhance the gloss and transmittance of the graphic colors presented by the electronic ink layer 4. The light-transmitting layer 2 is disposed between the first protective layer 1 and the electronic ink layer 4.

[0049] Optionally, the light-transmitting layer 2 may include a PET film 22 and an OCA film 21. The OCA film 21 is disposed between the PET film 22 and the first protective layer 1 to increase the adhesion between the first protective layer 1 and the electronic ink layer 4.

[0050] Optionally, the first protective layer 1 can be Corning CG7 glass with a thickness ranging from 0.45mm to 0.65mm, or 0.55mm.

[0051] Optionally, the PET film 22 includes a UV transfer texture, an optical coating, and an offset pattern layer, with a thickness ranging from 0.05 mm to 0.15 mm, and can be 0.1 mm.

[0052] Optionally, the color-changing structure may also include an optical adhesive film 41, with the electronic ink layer 4 serving as the color-changing layer of the housing, including a composite film 42 and an electronic ink film 43. The optical adhesive film 41 is used to increase the adhesion between the electronic ink layer 4 and the light-transmitting layer 2 and the backing layer 5, and the composite film 42 is used to increase the conductivity and transmittance of the electronic ink film 43. The electronic ink film 43 can change color when energized to present images of different colors and shapes, and the electronic ink film 43 used in each color-changing area includes at least four colors of electronic ink.

[0053] Optionally, the composite film 42 is disposed on the side of the electronic ink film 43 facing the first protective layer 1, and the optical adhesive film 41 is attached to the other surface of the composite film 42 and the electronic ink film 43. Optionally, the composite film 42 includes a PET film and an ITO film.

[0054] Optionally, the electronic ink film 43 can be a Prism3S electronic ink film, and the electronic ink film 43 can contain four colors: red, yellow, white and blue; the thickness of the electronic ink layer 4 ranges from 0.16mm to 0.19mm, and can be 0.175mm.

[0055] Optionally, the backplate layer 5 serves as the driving circuit layer for segment-code ink color changing. Based on the desired graphic shape, the backplate layer 5 is transformed into a circuit design scheme, dividing it into at least two accommodating portions. Each accommodating portion houses and corresponds to a color-changing area, thus dividing the electronic ink film 43 into segment-code color-changing areas. By partitioning the driving circuit of the backplate layer 5 in this way, at least 46 independent color changes can be achieved. The segment-code ink screen design not only enables color changing of the casing but also improves the clarity of the graphics. Optionally, on existing printed graphics, this color-changing area can achieve a maximum of 63 color changes. The backplate layer 5 also includes a conductive layer, which increases the conductivity of the backplate layer 5 and the adhesion between the backplate layer 5 and the electronic ink layer 4. This conductive layer is formed by finely printing conductive material onto the accommodating portions. The backplate layer 5 is tightly bonded to the electronic ink layer 4 through the conductive layer, thereby achieving a thinner and lighter color-changing structure and casing. Optionally, the back sheet layer 5 can be a PET back sheet with a thickness ranging from 0.04mm to 0.06mm, and can be 0.05mm; the conductive layer can be a silver paste layer, and the conductive material can be carbon silver paste material, which does not have a shielding effect on the mobile phone antenna.

[0056] Optionally, the housing assembly may further include a waterproof structure 3, a second protective layer 6, and an ink area 7. The waterproof structure 3 provides waterproofing around the perimeter of the housing and is located at the edge of the light-transmitting layer 2 and the electronic ink layer 4 of the color-changing structure. The second protective layer 6 provides waterproof protection for the backplate layer 5 and the electronic paper film layer 4. Both the color-changing structure and the backplate layer 5 are sandwiched between the second protective layer 6 and the light-transmitting layer 2. The ink area 7 is used to shield areas outside the color-changing area, serving a visual aesthetic purpose, and is located around the first protective layer 1. Optionally, the second protective layer 6 can be a hot-melt film, which can optimize the overall thickness of the housing and solve the problem of aluminum film shielding mobile phone models; the thickness of the second protective layer 6 ranges from 0.04mm to 0.06mm, and can be 0.05mm.

[0057] The electronic ink film 43 is divided into multiple color-changing areas by the backplane layer 5. Each color-changing area changes color independently. Users can change the color of the selected pattern template. Optionally, there can be multiple pattern templates, and the pattern templates correspond one-to-one with the circuit design of the backplane layer 5.

[0058] In summary, this application provides a housing assembly including a backplate layer 5 and an electronic ink layer 4. The electronic ink layer 4 includes an electronic ink film 43, and the backplate layer 5 is disposed on the side of the electronic ink layer 4 facing away from the first protective layer 1. On one hand, the backplate layer 5 is converted into a circuit design according to the desired graphic shape, dividing the backplate layer 5 into multiple regions, thereby enabling the electronic ink film 43 to change color in a segment code manner. This allows for independent color changes in multiple segments and improves the clarity of the graphic. On the other hand, a conductive layer is provided on the backplate layer 5, which increases the conductivity of the backplate layer 5 and the adhesion between the backplate layer 5 and the electronic ink layer 4, enabling the housing to achieve a thin and lightweight segment code color change. In addition, in this embodiment, the segment code color change of the graphic is directly presented on the housing assembly, eliminating the need for an external protective sleeve and an electronic ink screen.

[0059] like Figure 3 As shown, an embodiment of this application also provides a smart terminal, including the aforementioned housing assembly.

[0060] Optionally, the smart terminal may also include an IC chip 8, which provides a computer program for storing color-changing graphics. The IC chip may be disposed on the backplane layer 5 of the housing assembly. The IC chip is electrically connected to the electronic ink layer 4 of the color-changing structure and controls the color-changing logic of the electronic ink layer 4.

[0061] The housing assembly enables independent color changes across multiple color-changing areas. Working in conjunction with the IC chip 8, it not only changes the color of graphic templates but also displays the selected graphic template dynamically in real time. The specific principle is as follows: the user selects the desired graphic and color on the smart terminal. The IC chip 8 uses a pre-set animation program to control the electronic ink layer 4 to display the graphic templates sequentially, creating a color-changing animation. The graphic templates are not limited to fixed patterns, mood patterns, charging displays, or notification displays. Users can customize graphics and colors according to pre-designed patterns and colors in different scenarios, offering high playability.

[0062] In summary, the embodiments of this application also provide a smart terminal, including the aforementioned housing component and IC chip 8. The IC chip 8 stores a graphic color-changing program and controls the color-changing logic of the electronic ink layer 4 of the housing, which can realize the real-time and dynamic display and color-changing of various graphic templates, greatly increasing the user's interest and viewing experience during the graphic color-changing process.
