Referring to FIG. 5, a driving module 1000 may be disposed in an electroactive device 2000 having a unique structure.

In the trench structure 2100, a partial region of the first electrode 2010 and a partial region of the intermediate layer 2030 are removed, so that a partial region of the plurality of regions of the second electrode 2050 is directed toward the first electrode 2010. It may be a structure that allows it to be exposed.

Hereinafter, the trench structure 2100 of the electroactive device 2000 will be described in detail.

Referring to FIG. 6, the trench structure 2100 may be formed in a region adjacent to the side of the electroactive device 2000.

As the trench structure 2100 is formed, a partial region of the first electrode 2010 and the intermediate layer 2030 may be removed.

The trench structure 2100 may be formed adjacent to the side of the electroactive device 2000, and the trench structure 2100 may be formed to be spaced apart from the side of the electrochromic device 2200.

As shown in FIG. 6(a), when the trench structure 2100 is formed adjacent to the side of the electroactive element 2000, the trench structure 2100 is a side surface of the electroactive element 2000. It may be formed so that a portion of the ablation (removal). The trench structure 2100 may be formed to have a shape in which one region of the side of the first electrode 2010 of the electrochromic element 2200 and one region of the side of the intermediate layer 2030 are removed. Accordingly, a partial cross-section of the first electrode 2010 and a partial cross-section of the intermediate layer 2030 may be exposed in an outward direction.

As described above, when the trench structure 2100 is formed to be connected to the side of the electroactive device 2000, the process can be simplified.

The electrode layer may have predetermined optical properties.

The first electrode 2010 and/or the second electrode 2050 may transmit light. That is, each electrode may be implemented as a transparent electrode.

That is, when the electrochromic layer 2031 is oxidized, the ion storage layer 2033 is reduced, and when the electrochromic layer 2031 is reduced, the ion storage layer 2033 may be oxidized.

Accordingly, the ion storage layer 2033 may function as a counter electrode of the electrochromic layer 2031.

The ion storage layer 2033 and the electrochromic layer 2031 may cause a state change corresponding to each other. For example, when the ion storage layer 2033 is oxidatively colored, the electrochromic layer 2031 is also reduced-colored, and when the ion storage layer 2033 is reduced and decolored, the electrochromic layer 2031 is also oxidatively bleached.

The electrolyte layer 2032 may be a passage for ions between the electrochromic layer 2031 and the ion storage layer 2033. The electrochromic layer 2031 and the ion storage layer 2033 may exchange ions through the electrolyte layer 2032. The electrolyte layer 2032 may serve as an ion transport layer and may block electron transfer. The electrochromic layer 2031 and the ion storage layer 2033 may be insulated from each other, but may be disposed on the electrochromic element 2200 to conduct ion conduction. That is, the electrolyte layer 2032 may inhibit the movement of electrons across the electrolyte layer 2032, but permit the movement of ions.

The electrolyte layer 2032 may include an insulating material.

The driving module 1000 may be disposed so that a control signal can be transmitted to the electrochromic element 2200 through a region in which the trench structure 2100 of the electrochromic element 2200 is formed.

The electrical connection part 1530 included in the driving module 1000 may be disposed in a trench structure of the electrochromic element 2200.

The driving substrate 1310 on which the driving unit 1300 is implemented may be disposed around the electrochromic element 2200. As described above, when the electrochromic device is implemented as an electrochromic mirror, the driving substrate 1310 may be disposed on the rear surface of the reflective surface of the electrochromic element 2200. Alternatively, when the electrochromic element 2200 is implemented as an electrochromic window, the driving substrate 1310 may be disposed so as not to affect a path of light passing through the electrochromic element 2200.

In the pressing/heating step (S1540 ), a process of pressing the driving module 1000 so that the driving module 1000 is fixed to the electrochromic element 2200 may be performed. When the driving module 1000 is fixed to the electrochromic element 2200, an electrochromic module may be implemented.

A process of pressing the driving module 1000 so that the driving module 1000 is fixed may be performed. The pressing direction may be a direction perpendicular to the lower portion from the upper portion of the electrochromic element 2200.

The anisotropic conductive film disposed on the electrochromic element 2200 may be fixed according to the pressing process.

The adhesive film of the anisotropic conductive film may be inserted into a depression included in the trench structure 2100 of the electrochromic element 2200 by a pressing process. The adhesive film may be adhered to an upper portion of the first electrode 2010 of the electrochromic element 2200 and an upper portion of the exposed second electrode 2050.

In addition, conductors 1530 positioned between the driving unit 1300 and the electrochromic element 2200 are brought into contact with each other by the pressing process, thereby forming a conduction path. The conduction path may be formed as a path in a direction corresponding to a pressing direction.

In addition, the conductor 1530 included in the anisotropic conductive film fixed by the pressing process may electrically connect the first electrode 2010 and the driving unit 1300, the second electrode 2050 and the driving unit 1300. have.

Accordingly, the driving unit 1300 and the electrical connection unit 1350 may be electrically connected along the above-described conduction path.

Meanwhile, a heating process of applying a predetermined heat in addition to the pressing process may be additionally performed. According to the additionally performed heating process, the adhesive film may be better adhered to the electrochromic device 2200 physically/chemically.

In the packaging step S1550, the electrochromic module implemented in the above-described step may be implemented as an electrochromic device. In the packaging step, a housing for protecting the electrochromic module implemented based on the implementation/design purpose from an external environment may be coupled to the electrochromic module.

In the electrochromic device process according to the embodiment of the present application described above, the step of configuring each embodiment is not essential, and therefore, each embodiment may selectively include the above-described steps. In addition, each step constituting each embodiment is not necessarily performed in the order described, and the steps described later may be performed before the steps described earlier. It is also possible for each step to be repeatedly performed during the operation.

Hereinafter, the electrochromic process will be described.

The electrochromic device according to the exemplary embodiment of the present application may be electrochromic. Hereinafter, the electrochromic of the electrochromic device will be described in detail.

16 is a flowchart illustrating an electrochromic method according to an exemplary embodiment of the present application.

Referring to FIG. 16, the step of the electrochromic method may include generating/transferring driving power (S1610), forming an effective voltage (S1620), electrochromic (S1630), and the like. Steps S1610 to S1630 may all be performed, but not all steps S1610 to S1630 should always be performed, and only at least one of steps S1610 to S1630 may be performed.

In the step of generating/transmitting driving power (S1610), driving power for driving the electrochromic element 2200 may be generated, and the generated driving power may be applied to the electrochromic element 2200. The driving power formed in the above-described driving unit 1300 may be output to the electrical connection unit 1500, and the driving power applied to the electrical connection unit 1500 is transmitted to the electrode layer of the electrochromic element 2200 through the conductor 1530 Can be.

The driving power may be generated from the driving unit 1300 described above. The driving power is electric power for discoloring the electrochromic element 2200, and may have a voltage value or a current value for activating the electrochromic element 2200.

The generated driving power may be conducted to the electrochromic element 2200 through the electrical connection unit 1350.

The electrochromic device 2200 according to the exemplary embodiment of the present application may receive driving power through the electrical connection unit 1350. The driving power may be delivered to the electrochromic element 2200 through a conduction path formed between the driving unit 1300 of the electrochromic element 2200. As described above, the conduction path may be formed by contacting the conductors 1530 with each other.

In the effective voltage forming step, an effective voltage for discoloring the electrochromic element 2200 may be formed.

An effective voltage may be formed based on the driving power applied to the electrochromic element 2200. The effective voltage may be formed based on a difference between the first driving power applied to the first electrode 2010 included in the electrochromic element 2200 and the second driving power applied to the second electrode 2050.

The effective voltage may be formed in the entire area of the electrochromic element 2200.

17 is a diagram showing an effective voltage formed in an electrochromic device according to an exemplary embodiment of the present application.

As shown in FIG. 17A, when an anisotropic conductive film is disposed in a region of the side of the electrochromic element 2200, an effective voltage may be formed in one direction of the electrochromic element 2200. The effective voltage may be an index indicating an amount of supplying electrons as an electric power source. That is, as the effective voltage increases, the amount of electrons supplied to the electrochromic element 2200 may increase.

Referring to FIG. 17B, effective voltages formed in all regions of the electrochromic element 2200 may be different for each region. The effective voltage may be different for each region due to a voltage drop caused in one direction. That is, an effective voltage may be formed in the electrochromic element 2200 so that the effective voltage has a value continuously dropped in one direction of electrochromic.

Specifically, the effective voltage in the region of the side of the electrochromic element 2200 in which the electrical connection part 1350 is disposed may be the first effective voltage, and the effective voltage in the region adjacent to the region may be the second effective voltage. have. The second effective voltage may be a voltage lower than the first effective voltage.

The first effective voltage may be a difference between the first driving power and the second driving power, but the effective voltage in a region adjacent to the region may be a value smaller than the difference between the first driving power and the second driving power.

In the electrochromic step, the transmittance/absorptivity of the electrochromic element 2200 may be changed. The color of the electrochromic device 2200 may be changed.

The electrochromic device 2200 may be electrochromic according to a predetermined electrochromic mechanism based on the above-described effective voltage.

The electrochromic mechanism may include an electrochromic ion transfer step, and an oxidation/reduction and discoloration step.

In the electrochromic ion transfer step, electrochromic ions for electrochromic may be moved within the electrochromic element 2200.

The electrochromic ions may be moved based on the above-described effective voltage. Electrochromic ions may be moved from a region having a high electrical potential (high voltage) to a region having a low potential (low voltage) based on the effective voltage.

The electrochromic ions may be moved due to electrons donated to the electrochromic device 2200. As a predetermined coulomb's force is generated between the electrons and the electrochromic ions, the electrochromic ions may move to a region of the electrochromic element 2200 to which electrons are supplied.

In the oxidation/reduction reaction and discoloration step, an oxidation/reduction reaction occurs in the electrochromic element 2200, and the electrochromic element 2200 may be discolored due to the oxidation/reduction reaction.

The oxidation/reduction reaction and color change reaction may occur in the electrochromic layer 2031 and/or the ion storage layer 2033 of the electrochromic device 2200.

The electrochromic ions may cause an oxidation/reduction reaction with a predetermined electrochromic material contained in the electrochromic layer 2031 and/or the ion storage layer 2033.

18 is a view showing electrochromic color according to an embodiment of the application.

Referring to FIG. 18, the optical state of the electrochromic element 2200 may be changed from the trench structure of the electrochromic element 2200.

Referring to FIG. 18 (a), electrochromic discoloration may proceed in one direction or the other direction from the electrical connection unit.

Coloring can occur inward from the trench structure. Also, discoloration can occur inward from the trench structure.

The coloration degree of each region of the electrochromic element 2200 and/or the time when the transmittance becomes uniform may be different. When the electrochromic device 2200 includes a first region and a second region, and the transmittance of the first region is the first transmittance and the transmittance of the second region is the second transmittance, the value of the first transmittance and the second transmittance A predetermined time may be required for the transmittance value to become the same transmittance value. The first region may require a first time t1, and the second region may require a second time t2.

The time (t) may be defined as a critical time at which discoloration of the electrochromic element becomes uniform. The threshold time may be proportional to the magnitude of the voltage. Therefore, when the magnitude of the applied voltage is relatively large, the voltage is applied for a longer period of time, and when the magnitude of the applied voltage is relatively small, the voltage is applied for a shorter period of time to prevent homogeneous discoloration of the electrochromic element. You can induce it.

On the other hand, as shown in Figure 18 (b), the electrical connection may be disposed on the four sides of the electrochromic element. In this case, when the electrochromic element is colored, the coloring may proceed toward the center of the electrochromic element over time.

As described above, in the case of an electrochromic module including an electrochromic element 2200 having a trench structure 2100 and an electric connection portion having anisotropic conductivity, the arrangement of the driving module 1000 may be simplified. . The production process of the electrochromic module may be simplified.

In order to be driven, the electrochromic element 2200 needs to receive driving power through the first electrode 2010 and the second electrode 2050.

When the trench structure 2100 is not formed, the electrochromic element 2200 must receive power from different locations. For example, the first electrode 2010 receives driving power from the driving module 1000 disposed in the upper direction, and the second electrode 2050 is driving power from the driving module 1000 disposed in the lower direction. Must be supplied. That is, when the trench structure 2100 is not formed, since the driving module 1000 must be disposed at different positions of the electrochromic element 2200, the structure of the electrochromic module may be complicated. Since a process must be additionally performed so that the driving module 1000 is disposed at different positions, the process may be complicated.

Alternatively, in order for the electrochromic element 2200 on which the trench structure 2100 is not formed to receive power from the same direction, the electrochromic element 2200 must have electrodes of different areas. For example, since the area of the second electrode 2050 is increased, the second electrode 2050 must be exposed in an external direction of the first electrode 2010. Accordingly, the regions of the first electrode 2010 and the exposed second electrode 2050 from the upper direction can receive power. When the electrodes of the electrochromic element 2200 have different areas, the processes for forming each electrode cannot be performed in the same process. A process for forming each electrode must be performed separately. Accordingly, when the trench structure 2100 is not formed, a process for producing the electrochromic module may be complicated. In addition, since at least one electrode has to have a larger area than the other electrode, the electrochromic device 2200 having different areas may make it difficult to miniaturize the electrochromic module. In addition, when the exposed area of the second electrode 2050 is not entirely covered, the electrochromic device 2200 may be electrically unstable.

On the other hand, when the trench structure 2100 is provided, the manufacturing process of the electrochromic module may be simplified, and the arrangement of the driving module 1000 may be simplified. In the electrochromic device 2200 having the trench structure 2100, an electrode may be exposed in one direction. Accordingly, the driving module 1000 may be disposed at a position corresponding to the one direction. The electrochromic device 2200 may receive driving power to the first electrode 2010 and the second electrode 2050 through the driving module 1000 disposed in one direction. That is, since the driving module 1000 only needs to be arranged in one direction of the electrochromic element 2200, it can be simplified to arrange the driving module 1000. Accordingly, the production process of the electrochromic module can be simplified. In addition, since at least one electrode included in the electrochromic element 2200 having the trench structure 2100 does not have to have a larger area than other electrodes, it may be helpful for miniaturization of the electrochromic device. In addition, since each electrode exposed through the trench structure 2100 may be covered by the base of the electrical connection part, it may have an effect of being electrically stable.

A conduction path may not be formed between the buffer region 1100 and the driving substrate 1310.

The buffer region 1100 may be formed between the first electrode 2010 of the trench structure 2100 of the electrochromic element and the exposed second electrode 2050. The buffer area 1100 may be formed between the protruding portion 2130 and the recessed portion 2110. The buffer area 1100 may be formed between the pad portion 2140 and the contact portion 2150. The buffer region 1100 may be formed in a region corresponding to a connection surface or a depression surface.

When the electrochromic device includes a first region, a second region, and a third region, the first region is a region of a first electrode, the second region is a buffer region 1100, and the third region May be the area of the second electrode. The first region may be a pad part 2140, a third region may be a contact part 2150, and the second region may be a buffer region 1100, and the second region may be a connection surface or a partial region of a depression surface. .

The buffer area 1100 may be implemented by a connection part 1330 provided on the driving substrate 1310.

As the distance between the connection parts 1330 is adjusted, the connection part 1330 may not be formed in a region of the driving substrate 1310 corresponding to the buffer region 1100. By separating the connection part 1330, the connection part 1330 may not be formed at the position of the driving substrate 1310 corresponding to the buffer area 1100.

Even if the conductive surface 1541 of the conductive coating conductor 1540 is in contact with the insulating layer, a conductive path may not be formed. Driving power delivered to the base buffer region 1513 cannot be delivered. When the base buffer region 1513 is a layer that does not include the conductive coating conductor 1540, the driving power cannot be transmitted.

A short phenomenon may occur in the electrochromic device 2200. On the other hand, when the buffer region 1100 is formed, a short-circuit phenomenon of the pad portion 2140 and the contact portion 2150 can be prevented.

Further, although not shown, the trench structure 2100 may have an inclination. When the trench structure 2100 has an inclination, a plurality of conductors 1540 may contact the connection surface 2170 or the depression surface 2160. Accordingly, when driving power is applied to the connection surface 2170 or the depression surface 2160, the electrochromic element 2200 may be damaged.
