Abstract

A terminal, a color changing method, and a color changing apparatus that relate to the field of communications technologies are provided, so as to resolve a technical problem of a waste of materials due to production of a terminal shell. A color changing unit is disposed inside a terminal, where the color changing unit can change a color when receiving electrical energy, and a transparency value of a shell is greater than a first preset transparency value, so that a technical problem of a waste of materials due to production of a terminal shell can be effectively resolved, which can reduce manufacturing materials and is conducive to environmental protection.

Claims

1. A terminal, comprising:

a color changing unit;

a shell, wherein a transparency value of the shell is greater than a first preset transparency value, and wherein the first preset transparency value is a transparency value that enables a user to see a color changing unit located inside the shell;

a power supplying unit disposed inside the shell and configured to supply power to the color changing unit,

wherein the color changing unit is connected to the power supplying unit, attached to an inner side of the shell or attached to an outer side of the shell, and configured to change a color when receiving electrical energy provided by the power supplying unit, and

wherein the color changing unit adjusts, according to a correspondence between a voltage value and a color, a current color value of the color changing unit as a first color value corresponding to the first voltage value when receiving a first voltage value from the power supply unit.

2. The terminal according to claim 1, wherein the color changing unit is at least one layer of color changing film that implements color changing by means of electrochromism.

3. The terminal according to claim 2, wherein the at least one layer of color changing film comprises at least one of:

M layers of first color changing film, wherein M is a positive integer;

N layers of second color changing film, wherein N is a positive integer; and

M layers of first color changing film and N layers of second color changing film, wherein M is a positive integer and N is an integer not less than 0, or M is an integer not less than 0 and N is a positive integer.

4. The terminal according to claim 3, wherein the first color changing film comprises a first transparent conducting layer, a first electrochromic layer, a first ion conductor layer, a first ion storage layer, and a second transparent conducting layer that are stacked in sequence, and wherein the second color changing film comprises a third transparent conducting layer, a second electrochromic layer, a second ion conductor layer, a second ion storage layer, and a metal layer that are stacked in sequence.

5. The terminal according to claim 4, wherein a color of the metal layer is a second color, and wherein the second color is the same as or different from a first color.

6. The terminal according to claim 1, wherein the shell comprises a top-layer shell and a bottom-layer shell that is disposed opposite to the top-layer shell, and wherein the color changing unit is attached to at least one of:

an inner side of the top-layer shell;

an outer side of the top-layer shell;

an inner side of the bottom-layer shell;

an outer side of the bottom-layer shell;

an inner side of the top-layer shell and an inner side of the bottom-layer shell;

an outer side of the top-layer shell and an outer side of the bottom-layer shell;

an inner side of the top-layer shell and an outer side of the bottom-layer shell; and

an outer side of the top-layer shell and an inner side of the bottom-layer shell.

7. The terminal according to claim 6, wherein the terminal further comprises a displaying unit disposed inside the top-layer shell of the shell and configured to display local data or data acquired from another electronic device.

8. The terminal according to claim 1, wherein the terminal further comprises a processor located inside the shell, wherein the processor is connected to the power supplying unit, and wherein the processor is configured to:

receive selection information of the user; and

determine, according to the selection information, that the user selects a first color, wherein a color value of the first color is the first color value.

9. The terminal according to claim 1, wherein the terminal further comprises a processor located inside the shell, wherein the processor is connected to the power supplying unit, and wherein the processor is configured to:

obtain a first environment color, wherein the first environment color is a color of a surrounding environment of the terminal;

match the first environment color with a stored color; and

determine a first color whose degree of color matching with the first environment color is within a first preset threshold, wherein a color value of the first color is the first color value, and wherein the first preset threshold is used to indicate that the first environment color and the first color are adjacent colors or similar colors.

10. A color changing method, wherein the method is applied to a terminal, wherein the terminal comprises a shell and a color changing unit that is attached to an inner side of the shell or attached to an outer side of the shell, and wherein the method comprises:

obtaining a first color value;

determining, according to a correspondence set of a color value and a voltage value, a first voltage value corresponding to the first color value; and

providing the first voltage value for the color changing unit, such that a color value of the color changing unit is changed from an initial color value to the first color value.

11. The method according to claim 10, wherein obtaining the first color value comprises:

receiving selection information of a user; and

determining, according to the selection information, that the user selects a first color, wherein a color value of the first color is the first color value.

12. The method according to claim 10, wherein obtaining the first color value comprises:

obtaining a first environment color, wherein the first environment color is a color of a surrounding environment of the terminal; and

matching the first environment color with a stored color, and determining a first color whose degree of color matching with the first environment color is within a first preset threshold, wherein a color value of the first color is the first color value, and wherein the first preset threshold is used to indicate that the first environment color and the first color are adjacent colors or similar colors.

13. A color changing apparatus, comprising:

a shell;

a color changing unit that is attached to an inner side of the shell or attached to an outer side of the shell;

a processor configured to;

obtain a first color value; and

determine, according to a correspondence set of a color value and a voltage value,

a first voltage value corresponding to the first color value; and

a power supplying unit configured to provide the first voltage value for the color changing unit according to an instruction of the processor,

wherein the color changing unit is configured to adjust a current color value of the color changing unit as the first color value corresponding to the first voltage value when receiving the first voltage value.

14. The apparatus according to claim 13, wherein the processor being configured to obtain the first color value comprises:

receiving selection information of a user; and

determining, according to the selection information, that the user selects a first color, wherein a color value of the first color is the first color value.
