the first side of the housing 100 is covered with an optical coating 200, which is covered with ink 300.
As further shown in fig. 2, the plurality of protrusions 110 are uniformly distributed on the housing at equal intervals, for example, when the housing is specifically configured, the interval between the protrusions is 400 nm, and the protrusions are arranged horizontally and vertically on the housing 100, so that the final effect is substantially consistent from the top, bottom, left and right.
Further, the size of each protrusion is the same, and in particular, the length and width of each protrusion 110 are set to 400 nm. Each protrusion 110 is further provided with grooves 111 arranged in a longitudinal and transverse direction, for example, the vertical and horizontal lines on the protrusion 110 in fig. 2 represent grooves, and when setting, the protrusion 110 is usually provided with 100 × 100 grooves, that is, 100 transverse grooves, and 100 longitudinal grooves, each groove representing 1 light diffraction slit.
The existing theory is as follows: from the perspective of front view, the distance is 200 nanometers, and the diffracted light is blue; the distance is 400 nanometers, and the diffracted light is green; the distance is 600 nanometers, and the diffracted light is red; because the housing 100 of the embodiment of the present invention has two types of slits, namely: the gaps of 400 nanometers between the protrusions and the gaps smaller than 400 nanometers arranged in each protrusion allow light to pass through the gaps with different sizes through different incident angles and diffract a plurality of colors, so that a user can see different colors at different angles, and the user can see the colorful effect of the shell.
In order to enhance the reflection of light, the plurality of protrusions need to be covered with an optical coating, and in order to increase the metal texture when the light is reflected, the optical coating is usually configured as a metal coating, and specifically, the optical coating sequentially includes, from the position close to the housing to the position far away from the housing: titanium dioxide (TiO)2) Layer, silicon dioxide (SiO)2) A layer, a titanium dioxide layer; this arrangement is achieved by separating the two layers of titanium dioxide with silicon dioxide.
Specifically, the thickness of both titanium dioxide layers is 168.2 nanometers, and the thickness of the silicon dioxide layer is 143.3 nanometers.
It should be noted that, in the embodiment of the present invention, the metal texture can be effectively enhanced by using a multi-layer metal plating manner.
Further, since the housing has a function of shielding the internal components of the terminal, the optical coating film is covered with ink, and the thickness of the ink is usually 21 to 27 μm in order to prevent the ink from falling off and not to increase the thickness of the housing excessively.
It should be noted that, by arranging the plurality of protrusions on the shell, and arranging the plurality of grooves which are vertically and horizontally arranged on each protrusion, light can be diffracted to emit light with different colors through different grooves, so that the problems of single shell color and visual fatigue of a user can be solved.
The embodiment of the invention also provides a terminal which comprises the shell.
It should be noted here that the housing includes two sides, the first side is provided with a plurality of protrusions, each protrusion is provided with a plurality of grooves arranged vertically and horizontally, and covers the optical coating and the ink; the second side is not provided with any structure, after the shell is arranged on the terminal, the second side of the shell is exposed outside the terminal, a user can directly contact the second side, and the first side of the shell is positioned inside the terminal and cannot be touched by the user.
The terminal provided with the housing can change the color of the housing of the terminal along with the change of the visual angle of a user, thereby improving the user experience.

wherein the thickness of the titanium dioxide layer is 168.2 nanometers, and the thickness of the silicon dioxide layer is 143.3 nanometers.
It should be noted that the specific implementation process of step 302 is as follows: under the vacuum condition, the titanium dioxide target material and the silicon dioxide target material are respectively dissolved by directly heating or indirectly heating (the temperature is 60-70 ℃), then evaporated (or directly sublimated into gas from solid), atoms or molecules with enough energy are obtained under the action of glow discharge and fly to and deposit on the surface of the PET sheet material, and a certain number of layers and thickness of metal film layers are deposited, so that the PET sheet material has strong metal reflection texture.
Further, the specific implementation manner of step 303 is: carrying out three times of ink printing on the optical coating, wherein the three times of ink printing refers to firstly carrying out the first time of ink printing, the thickness of the ink is 7-9 microns, and then baking, wherein the baking temperature is 80 ℃ (the error range is 0-5 ℃), and the baking time is 30 minutes; then printing ink for the second time, wherein the thickness of the ink is 7-9 microns, and then baking at 80 ℃ (error range is 0-5 ℃) for 30 minutes; and finally, printing the ink for the third time, wherein the thickness of the ink is 7-9 microns, and then baking for 30 minutes at the baking temperature of 80 ℃ (the error range is 0-5 ℃).
It should be noted that, this arrangement can effectively prevent the ink from falling off without increasing the thickness of the casing too much.
After the PET sheet sprayed with the ink is obtained, the PET sheet is cut according to the size and the shape of the shell required to be used, and the shell with the corresponding shape can be obtained.
Through the processing mode, the shell reflecting different colors along with the change of the visual angle of the user can be obtained, and when the shell is applied to the terminal, the use experience of the user on the terminal can be improved.
