Referring to fig. 5, fig. 5 is a schematic flow chart illustrating a method for manufacturing a color-changing device according to an embodiment of the present disclosure. The preparation method of the color-changing assembly specifically comprises the following steps:
101, a first preset working voltage of the liquid crystal panel and a first preset thickness of a liquid crystal layer in the liquid crystal panel are obtained.
The liquid crystal panel comprises a lower substrate and an upper substrate, a liquid crystal layer is arranged between the lower substrate and the upper substrate, and external voltage is applied to two sides of the liquid crystal layer to drive liquid crystal molecules in the liquid crystal layer to deflect, so that light transmission of the liquid crystal layer is realized. The liquid crystal panel may be a liquid crystal display panel including data lines, scan lines, thin film transistors, and the like. The simplified liquid crystal panel can be realized by arranging control voltage on the upper substrate and the lower substrate without arranging data lines, scanning lines and thin film transistors.
The liquid crystal panel is driven by an alternating current signal, and when the alternating current signal reaches a voltage threshold, liquid crystal molecules of the liquid crystal layer change in a quick response manner and deflect by a preset angle. The preset angle may be 60 degrees, 75 degrees, 90 degrees, etc. The voltage threshold of the liquid crystal layer is related to the thickness of the liquid crystal layer, and the thicker the liquid crystal layer is, the higher the voltage threshold of the liquid crystal layer is, the higher the voltage of the alternating current signal for driving the liquid crystal plate to deflect is. A first preset working voltage of the liquid crystal panel and a first preset thickness of a liquid crystal layer in the liquid crystal panel are obtained. The first preset operating voltage may be a highest voltage of the alternating current signal, or may be a voltage threshold of liquid crystal layer deflection.
102, obtaining a second preset working voltage according to the first preset working voltage, wherein the second preset working voltage is smaller than the first preset working voltage.
After the first preset working voltage is obtained, if the first preset working voltage is higher, the first preset working voltage can be reduced to obtain a second preset working voltage. Specifically, the second preset operating voltage may be obtained proportionally, for example, 80% of the first preset operating voltage is obtained as the second preset operating voltage.
And 103, acquiring a second preset thickness of the liquid crystal layer according to the second preset working voltage, wherein the second preset thickness is smaller than the first preset thickness.
And obtaining a second preset thickness according to the proportional relation between the voltage threshold and the thickness of the liquid crystal layer after the second preset working voltage is obtained. For example, the second preset working voltage corresponds to a voltage threshold of the liquid crystal layer deflection, and then the reference thickness corresponding to the second preset working voltage can be obtained, so as to obtain a second preset thickness of the liquid crystal layer, where the second preset thickness is smaller than the reference thickness, and if the second preset thickness is smaller than the reference thickness deviation thickness, so as to ensure that the liquid crystal layer can deflect under many conditions. The second predetermined thickness may also be scaled, such as 1.1 times, 1.2 times, 1.5 times, etc., the reference thickness.
And 104, arranging a liquid crystal layer with a second preset thickness between the first substrate and the second substrate which are oppositely arranged to form the color changing assembly, wherein the liquid crystal layer with the second preset thickness comprises liquid crystal molecules and pigment molecules.
And arranging the liquid crystal layer with the second preset thickness between the first substrate and the second substrate to form a color-changing assembly, wherein the liquid crystal layer with the second preset thickness comprises liquid crystal molecules and pigment molecules. The second preset thickness is smaller than the first preset thickness, so that the driving voltage required by the liquid crystal layer with the second preset thickness is lower than that of the existing liquid crystal panel, the driving voltage of the color-changing assembly can be reduced, and the color-changing function of the color-changing assembly is realized. For example, the driving voltage of the conventional liquid crystal panel is an ac power of an operating voltage of 20V, and the driving voltage of the color changing assembly in the embodiment of the present application may be an ac power of an operating voltage of 15V, thereby reducing the power consumption of the color changing assembly.
In addition, the liquid crystal layer in the color changing member includes liquid crystal molecules and color changing molecules. Referring to fig. 6a and fig. 6b, fig. 6a is a first structural schematic diagram of a color-changing assembly provided in an embodiment of the present application, and fig. 6b is a second structural schematic diagram of the color-changing assembly provided in the embodiment of the present application. Among them, the liquid crystal layer in fig. 6a and 6b shows only a part of the liquid crystal molecules and the pigment molecules. The electrochromic assembly comprises a first substrate 31 and a second substrate 32 which are oppositely arranged, a liquid crystal layer 33 is arranged between the first substrate 31 and the second substrate 32, and the liquid crystal layer 33 comprises liquid crystal molecules 331 and pigment molecules 332. As shown in fig. 6a, when the color changing member does not apply an external voltage, the liquid crystal molecules 331 and the pigment molecules 332 in the liquid crystal layer 33 maintain a fixed state (e.g., a natural lateral state). As shown in fig. 6b, when an external voltage is applied to the color-changing device, i.e. an ac signal is applied to the first substrate 31 and the second substrate 32, the ac signal can drive the liquid crystal molecules 331 between the first substrate 31 and the second substrate 32, and the liquid crystal molecules 331 rotate according to the applied ac signal, thereby driving the pigment molecules 332 to rotate regularly. At this time, the area of the dye molecules 332 facing the outside becomes smaller, so that the color becomes lighter, and the color change is realized.
The first substrate 31 and the second substrate 32 may be transparent substrates such as glass substrates, plastic substrates, and resin substrates. The first substrate 31 and the second substrate 32 may be glass substrates, plastic substrates, resin substrates, or the like doped with colors, and then color mixing effect is achieved by combining the pigment molecules 332 in the liquid crystal layer 33.
Referring to fig. 7, fig. 7 is another schematic flow chart of a method for manufacturing a color-changing assembly according to an embodiment of the present disclosure. The preparation method of the color-changing assembly specifically comprises the following steps:
a first preset working voltage of the liquid crystal panel, a first preset thickness of a liquid crystal layer in the liquid crystal panel and a first ratio value of liquid crystal molecules to pigment molecules in the liquid crystal layer are obtained 201.
The liquid crystal panel comprises a lower substrate and an upper substrate, a liquid crystal layer is arranged between the lower substrate and the upper substrate, and external voltage is applied to two sides of the liquid crystal layer to drive liquid crystal molecules in the liquid crystal layer to deflect, so that light transmission of the liquid crystal layer is realized. The liquid crystal panel may be a liquid crystal display panel including data lines, scan lines, thin film transistors, and the like. The simplified liquid crystal panel can be realized by arranging control voltage on the upper substrate and the lower substrate without arranging data lines, scanning lines and thin film transistors.
The liquid crystal panel is driven by an alternating current signal, and when the alternating current signal reaches a voltage threshold, liquid crystal molecules of the liquid crystal layer change in a quick response manner and deflect by a preset angle. The preset angle may be 60 degrees, 75 degrees, 90 degrees, etc. The voltage threshold of the liquid crystal layer is related to the thickness of the liquid crystal layer, and the thicker the liquid crystal layer is, the higher the voltage threshold of the liquid crystal layer is, the higher the voltage of the alternating current signal for driving the liquid crystal plate to deflect is. A first preset working voltage of the liquid crystal panel, a first preset thickness of a liquid crystal layer in the liquid crystal panel, and a first ratio value of liquid crystal molecules and pigment molecules in the liquid crystal panel are obtained.
The first preset operating voltage may be a highest voltage of the alternating current signal, or may be a voltage threshold of liquid crystal layer deflection.
202, obtaining a second preset working voltage according to the first preset working voltage, wherein the second preset working voltage is smaller than the first preset working voltage.
After the first preset working voltage is obtained, if the first preset working voltage is higher, the first preset working voltage can be reduced to obtain a second preset working voltage. Specifically, the second preset operating voltage may be obtained proportionally, for example, 80% of the first preset operating voltage is obtained as the second preset operating voltage.
And 203, acquiring a second preset thickness of the liquid crystal layer according to the second preset working voltage, wherein the second preset thickness is smaller than the first preset thickness.
And obtaining a second preset thickness according to the proportional relation between the voltage threshold and the thickness of the liquid crystal layer after the second preset working voltage is obtained. For example, the second preset working voltage corresponds to a voltage threshold of the liquid crystal layer deflection, and then the reference thickness corresponding to the second preset working voltage can be obtained, so as to obtain a second preset thickness of the liquid crystal layer, where the second preset thickness is smaller than the reference thickness, and if the second preset thickness is smaller than the reference thickness deviation thickness, so as to ensure that the liquid crystal layer can deflect under many conditions. The second predetermined thickness may also be scaled, such as 1.1 times, 1.2 times, 1.5 times, etc., the reference thickness.
And 204, acquiring a second ratio value of the liquid crystal molecules and the pigment molecules in the liquid crystal layer with the second preset thickness according to the first preset thickness, the second preset thickness and the first ratio value, wherein the second ratio value is smaller than the first ratio value.
According to the first preset thickness and the first scale value, the color depth of the liquid crystal panel before the liquid crystal molecules and the pigment molecules are deflected can be obtained. After the second preset thickness is obtained, if the ratio of the liquid crystal molecules to the pigment molecules is still the first ratio, the total number of the pigment molecules is reduced, and the color depth of the liquid crystal layer is affected. For example, if the first predetermined thickness is 10 unit thicknesses, the second predetermined thickness is 5 unit thicknesses, and the first ratio value is 1:1, the second ratio value may be 1:2, 1:3, 2:3, and so on.
And 205, acquiring a liquid crystal layer with a second preset thickness according to the second proportion value, wherein the proportion of the liquid crystal molecules to the pigment molecules in the liquid crystal layer with the second preset thickness is the second proportion value.
After the second ratio value is obtained, a new liquid crystal layer is prepared, and the ratio of the liquid crystal molecules to the pigment molecules in the new liquid crystal layer is the second ratio value.
And 206, arranging a liquid crystal layer with a second preset thickness between the first substrate and the second substrate which are oppositely arranged to form the color changing assembly, wherein the liquid crystal layer with the second preset thickness comprises liquid crystal molecules and pigment molecules.
And arranging the liquid crystal layer with the second preset thickness between the first substrate and the second substrate to form a color change assembly, wherein the liquid crystal layer with the second preset thickness comprises liquid crystal molecules and pigment molecules, and the ratio of the liquid crystal molecules to the pigment molecules is a second ratio value. The second preset thickness is smaller than the first preset thickness, so that the driving voltage required by the liquid crystal layer with the second preset thickness is lower than that of the existing liquid crystal panel, the driving voltage of the color-changing assembly can be reduced, and the color-changing function of the color-changing assembly is realized. For example, the driving voltage of the conventional liquid crystal panel is an ac power of an operating voltage of 20V, and the driving voltage of the color changing assembly in the embodiment of the present application may be an ac power of an operating voltage of 15V, thereby reducing the power consumption of the color changing assembly.
In addition, the liquid crystal layer in the color changing member includes liquid crystal molecules and color changing molecules, and the liquid crystal molecules and the pigment molecules in the liquid crystal layer maintain a fixed state (e.g., a natural lateral state) when the color changing member is not applied with an external voltage. When the color-changing assembly applies external voltage, namely an alternating current signal is applied to the first substrate and the second substrate, the alternating current signal can drive liquid crystal molecules between the first substrate and the second substrate, and the liquid crystal molecules rotate according to the applied alternating current signal, so that the pigment molecules are driven to rotate regularly. At this time, the area of the dye molecules facing the outside becomes smaller, so that the color becomes lighter, and the color change is realized.
207, the pigment molecule comprises a first side and a second side which are adjacent, and the length of the first side is greater than that of the second side; the first side of the pigment molecule is parallel to the first substrate.
The pigment molecules 332 include a first side 3321 and a second side 3322 having different lengths, such that when the pigment molecules 332 are deflected, the first side 3321 of the pigment molecules 332 is parallel to the first substrate 31, or the second side 3322 is parallel to the first substrate 31, thereby realizing the color change of the color-changing element.
Specifically, the first side 3321 of the pigment molecules 332 is parallel to the first substrate 31 when the color changing assembly is in the idle state. When the color changing assembly is in an idle state, that is, when no external voltage is applied to the two ends of the color changing assembly, the first side 3321 of the pigment molecules 332 is parallel to the first substrate 31, the first side 3321 is long, and the color of the dark pigment is seen from the outside. When the pigment molecules 332 are deflected, the second side 3322 is parallel to the first substrate 31, and the outside is seen to be a light pigment color. A change of the color changing assembly from dark to light color can be achieved. The pigment molecules 332 may have an elliptical shape, a cylindrical shape, or the like.
In some embodiments, the step 207 can be replaced by placing the second side of the pigment molecule parallel to the first substrate.
When the color-changing assembly is in an idle state, the second side edges of the pigment molecules are parallel to the first substrate. When the color-changing assembly is in an idle state, namely when no external voltage is applied to the two ends of the color-changing assembly, the second side edge of the pigment molecule is parallel to the first substrate, the second side edge is shorter, and the external part sees the color of the light-colored pigment. When the pigment molecules are deflected, the first side edge is parallel to the first substrate, and the color of the dark pigment is seen from the outside. A change of the color changing component from light to dark can be achieved.
Referring to fig. 8, fig. 8 is a schematic flow chart illustrating a method for manufacturing a color-changing element according to an embodiment of the present disclosure. The preparation method of the color-changing assembly specifically comprises the following steps:
301, a first preset thickness of a liquid crystal layer in the liquid crystal panel and a first ratio of liquid crystal molecules to pigment molecules in the liquid crystal layer are obtained.
The liquid crystal panel comprises a lower substrate and an upper substrate, a liquid crystal layer is arranged between the lower substrate and the upper substrate, and external voltage is applied to two sides of the liquid crystal layer to drive liquid crystal molecules in the liquid crystal layer to deflect, so that light transmission of the liquid crystal layer is realized. The liquid crystal panel may be a liquid crystal display panel including data lines, scan lines, thin film transistors, and the like. The simplified liquid crystal panel can be realized by arranging control voltage on the upper substrate and the lower substrate without arranging data lines, scanning lines and thin film transistors.
The liquid crystal panel is driven by an alternating current signal, and when the alternating current signal reaches a voltage threshold, liquid crystal molecules of the liquid crystal layer change in a quick response manner and deflect by a preset angle. The preset angle may be 60 degrees, 75 degrees, 90 degrees, etc. The voltage threshold of the liquid crystal layer is related to the thickness of the liquid crystal layer, and the thicker the liquid crystal layer is, the higher the voltage threshold of the liquid crystal layer is, the higher the voltage of the alternating current signal for driving the liquid crystal plate to deflect is. A first preset thickness of a liquid crystal layer in a liquid crystal panel is obtained. The first preset thickness corresponds to a first preset working voltage, and the first preset working voltage may be a highest voltage of the alternating current signal or a voltage threshold of liquid crystal layer deflection. And simultaneously acquiring a first ratio value of liquid crystal molecules to pigment molecules in the liquid crystal layer.
302, obtaining a second preset thickness according to the first preset thickness, wherein the second preset thickness is smaller than the first preset thickness.
And after the first preset thickness is obtained, reducing the first preset thickness to obtain a second preset thickness. Specifically, the second predetermined thickness may be obtained proportionally, for example, obtaining a thickness of half of the first predetermined thickness to obtain the second predetermined thickness.
303, obtaining a second ratio of the liquid crystal molecules to the pigment molecules according to the first preset thickness, the second preset thickness and the first ratio, wherein the second ratio is smaller than the first ratio.
According to the first preset thickness and the first scale value, the color depth of the liquid crystal panel before the liquid crystal molecules and the pigment molecules are deflected can be obtained. After the second preset thickness is obtained, if the ratio of the liquid crystal molecules to the pigment molecules is still the first ratio, the total number of the pigment molecules is reduced, and the color depth of the liquid crystal layer is affected. For example, if the first predetermined thickness is 10 unit thicknesses, the second predetermined thickness is 5 unit thicknesses, and the first ratio value is 1:1, the second ratio value may be 1:2, 1:3, 2:3, and so on.
And 304, arranging a liquid crystal layer with a second preset thickness between the first substrate and the second substrate to form the color-changing assembly, wherein the ratio of the liquid crystal molecules to the pigment molecules in the liquid crystal layer with the second preset thickness is a second ratio value.
After the second ratio value is obtained, a new liquid crystal layer is prepared, and the ratio of the liquid crystal molecules to the pigment molecules in the new liquid crystal layer is the second ratio value. And arranging the liquid crystal layer with the second preset thickness between the first substrate and the second substrate to form a color change assembly, wherein the liquid crystal layer with the second preset thickness comprises liquid crystal molecules and pigment molecules, and the ratio of the liquid crystal molecules to the pigment molecules is a second ratio value. The second preset thickness is smaller than the first preset thickness, so that the driving voltage required by the liquid crystal layer with the second preset thickness is lower than that of the existing liquid crystal panel, the driving voltage of the color-changing assembly can be reduced, and the color-changing function of the color-changing assembly is realized. For example, the driving voltage of the conventional liquid crystal panel is an ac power of an operating voltage of 20V, and the driving voltage of the color changing assembly in the embodiment of the present application may be an ac power of an operating voltage of 15V, thereby reducing the power consumption of the color changing assembly.
In addition, the liquid crystal layer in the color changing member includes liquid crystal molecules and color changing molecules, and the liquid crystal molecules and the pigment molecules in the liquid crystal layer maintain a fixed state (e.g., a natural lateral state) when the color changing member is not applied with an external voltage. When the color-changing assembly applies external voltage, namely an alternating current signal is applied to the first substrate and the second substrate, the alternating current signal can drive liquid crystal molecules between the first substrate and the second substrate, and the liquid crystal molecules rotate according to the applied alternating current signal, so that the pigment molecules are driven to rotate regularly. At this time, the area of the dye molecules facing the outside becomes smaller, so that the color becomes lighter, and the color change is realized.

Referring to fig. 11, fig. 11 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device comprises a shell 15 and a color-changing assembly 30, wherein the color-changing assembly 30 is arranged on the shell 15, and the color-changing assembly 30 is prepared by adopting the method in any one of the above embodiments.
The housing 15 includes a bezel 151 and a rear case 152, the bezel 151 being disposed around the periphery of the rear case 152, and the color-changing assembly 30 being disposed on the rear case. The electronic device further includes a processor 36 electrically connected to the color changing assembly 30, and the processor 36 can control the driving voltage of the color changing assembly 30.
In some embodiments, the electronic device further includes a driving module 36, where the driving module 36 drives the liquid crystal layer of the color changing assembly by using a first ac electrical signal, and an operating frequency of the first ac electrical signal is a first operating frequency; when the voltage of the first ac signal reaches the preset voltage threshold, the driving module 36 drives the liquid crystal molecules and the pigment molecules of the liquid crystal layer to deflect by a preset angle; when the liquid crystal molecules and the pigment molecules of the liquid crystal layer need to maintain a deflection preset angle, the driving module 36 drives the liquid crystal layer by using a second alternating current signal, where the working frequency of the second alternating current signal is a second working frequency, and the second working frequency is smaller than the first working frequency.
The color-changing component comprises two color states, wherein the first color state is an initial color state, namely when no voltage is applied outside the color-changing component, the liquid crystal molecules and the pigment molecules are in the initial state such as the initial horizontal state, and if the pigment molecules are blue pigment molecules, the color-changing component is seen to be dark blue by a user in the first color state. The second color state is a color-changing state, that is, a state after a voltage is applied to the color-changing element and the liquid crystal molecules and the pigment molecules are rotated, for example, a state perpendicular to the first substrate, a user sees a light blue color in the second color state. When the liquid crystal molecules and the pigment molecules of the color changing assembly need to be deflected by a preset angle, namely, when the color changing assembly needs to be maintained in the second color state, the frequency of the alternating current for driving the color changing assembly can be reduced, so that the power consumption is reduced.
When the voltage of the first alternating current signal for driving the color-changing component reaches a certain threshold value, the liquid crystal molecules quickly respond and change to generate pulse current. No power is consumed during the state holding phase, in which case power consumption optimization can be achieved by reducing the frequency of the electrical signal driving the color changing component. In this way, the first alternating current signal can be replaced with a second alternating current signal having a second operating frequency that is less than the first operating frequency. To avoid the user being able to see the flicker problem, the frequency setting needs to be greater than 24 Hz. The first operating frequency of the first alternating current signal may be 100 hz.

Then, when one reserved application in at least two preset applications is detected to be in the working state, the reserved application in the working state is set as a target application, and then the color-changing component associated with the target application is driven by using the first alternating current signal.
