Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

As shown in fig. 1, 2 and 3, a cross-sectional view of the electrochromic-based light control glass according to the present embodiment in a front view direction and a cross-sectional view of the first light control plate 400 in the front view direction are shown, respectively. In a first aspect of the present embodiment, there is provided an electrochromic-based privacy glass comprising:

a first glass substrate 100, a first light modulation panel 400, a second glass substrate 200, a second light modulation panel 500, and a third glass substrate 300, which are stacked in this order; the first light modulation plate 400 includes a first transparent conductive layer 410, a first electrochromic layer 420, a first electrolyte layer 430, a first ion storage layer 440, and a second transparent conductive layer 450, which are sequentially stacked; the second light modulation plate 500 includes a third transparent conductive layer 510, a second ion storage layer 520, a second electrolyte layer 530, a second electrochromic layer 540, and a fourth transparent conductive layer 550, which are sequentially stacked; the first transparent conductive layer 410 and the fourth transparent conductive layer 550 each include a plurality of transparent electrodes 600.

In this way, in the present embodiment, the first light modulation plate 400 and the second light modulation plate 500 including the plurality of transparent electrodes 600, which are stacked, apply an electric field to the electrochromic layer corresponding thereto, so that the corresponding region of the electrochromic layer to which the electric field is applied changes color to realize filtering of incident light, and by respectively controlling on or off of each transparent electrode 600, color change of the corresponding region of the electrochromic layer can be selectively controlled to control filtering of incident light at a specific angle.

The existing household glass sunshade mode is mainly realized through a curtain and the like, the existing automobile window glass sunshade mode is mainly realized through a fabric sunshade screen, the fabric sunshade screen, a retractor, a hook and the like are integrated on the inner side of a rear door, and the sunshade screen is manually pulled out to be hung on the hook or is manually taken down from the hook to be furled by the retractor. Secondly, it is also a common way to block part of the sunlight or infrared radiation by attaching various films to the glass, such as a honeycomb film or an infrared reflective film or a visible light semi-permeable film can be attached to the window glass. In addition, the existing part of vehicles adopt electrochromic glass to realize sun shading, common electrochromic glass is usually integrated in a rear door of the vehicle, and the light transmittance of the glass is changed to realize the sun shading function by automatically or manually turning on and off a color-changing control power supply; however, the existing methods cannot selectively block light in a specific direction, and therefore, the vision of a passenger or a driver is often influenced while the sun is shielded.

Taking the electrically controlled light control glass of the present embodiment as an example of application to a window glass of an automobile, the window glass of the present embodiment is composed of a first glass substrate 100, a first light control plate 400, a second glass substrate 200, a second light control plate 500, and a third glass substrate 300, which are stacked in this order in the direction from the inside of the vehicle to the outside of the vehicle, wherein the first light control plate 400 is stacked in this order in the direction from the inside of the vehicle to the outside of the vehicleA first transparent conductive layer 410, a first electrochromic layer 420, a first electrolyte layer 430, a first ion storage layer 440, and a second transparent conductive layer 450; the second light modulation panel 500 is formed by sequentially laminating a third transparent conductive layer 510, a second ion storage layer 520, a second electrolyte layer 530, a second electrochromic layer 540, and a fourth transparent conductive layer 550 in a direction from the inside of the vehicle to the outside of the vehicle. The first transparent conductive layer 410 can be attached to the first glass substrate 100 by vacuum sputtering or screen printing, the first electrochromic layer 420 can be attached to the first transparent conductive layer 410 by vacuum sputtering or screen printing, the first electrolyte layer 430 can be attached to the first electrochromic layer 420 by vacuum sputtering or screen printing, the first ion storage layer 440 can be attached to the first electrolyte layer 430 by vacuum sputtering or screen printing, and the second transparent conductive layer 450 can be attached to the first ion storage layer 440 by vacuum sputtering or screen printing; it is understood that the second light modulation panel 500 may be manufactured in the same manner. The first electrochromic layer 420 and the second electrochromic layer 540 are made of an electrochromic material having a high visible light transmittance, for example, a molybdenum trioxide layer, a tungsten trioxide layer, a niobium pentoxide layer, or a titanium dioxide layer, and in this embodiment, the first electrochromic layer 420 and the second electrochromic layer 540 are tungsten trioxide thin films, that is, WO₃A film. The first transparent conductive layer 410, the second transparent conductive layer 450, the third transparent conductive layer 510, and the fourth transparent conductive layer 550 may be ITO layers or fluorine-doped ITO layers, and the first transparent conductive layer 410, the second transparent conductive layer 450, the third transparent conductive layer 510, and the fourth transparent conductive layer 550 in this embodiment all adopt ITO thin films. The first electrolyte layer 430 and the second electrolyte layer 530 are both solid electrolyte layers and are made of thin film materials with high visible light transmittance, high ion mobility and low electron mobility, and in the embodiment, the first electrolyte layer 430 and the second electrolyte layer 530 are made of LiO₂The material is prepared by vacuum sputtering or screen printing and the like.

The first transparent conductive layer 410 and the fourth transparent conductive layer 550 are etched into a plurality of independent and mutually insulated ITO electrodes in advance by etching the ITO thin films of the first transparent conductive layer 410 and the fourth transparent conductive layer 550, for example, the first transparent conductive layer 410 and the fourth transparent conductive layer 550 are divided into a plurality of strip-shaped electrodes from bottom to top along the horizontal direction of the light receiving surface of the window glass, all the strip-shaped electrodes are arranged along the horizontal direction of the light receiving surface of the window glass and extend along the axis of the transparent electrode 600, the first transparent conductive layer 410 or the transparent electrode 600, the second transparent conductive layer 450 in the horizontal direction, so that the plurality of strip-shaped electrodes are arranged in a louver structure on the light receiving surface of the window glass, wherein the strip-shaped electrodes of the first transparent conductive layer 410 correspond to the strip-shaped electrodes of the fourth transparent conductive layer 550 one to one. In order to further reduce the resistance of the ITO electrodes, conductive silver wires 700 are also printed on each ITO electrode in the present embodiment. In this embodiment, each ITO electrode on the first transparent conductive layer 410 of the first light modulation panel 400 is connected to a negative electrode of a power supply, and the second transparent conductive layer 450 is connected to a positive electrode of the power supply; each ITO electrode on the fourth transparent conductive layer 550 of the second light modulation panel 500 is also connected to the negative electrode of the power supply, and the third transparent conductive layer 510 is connected to the positive electrode of the power supply; in this way, each ITO electrode on the first transparent conductive layer 410 and the second transparent conductive layer 450 may independently form a loop, and the loop for each ITO electrode may be implemented by a switch circuit, for example, each ITO electrode is connected to a power supply through the switch circuit to form an independent loop, or each ITO electrode may be divided into groups as required, and ITO electrodes in different groups are respectively formed into different loops through the switch circuit to implement synchronous control on ITO electrodes in the same group. After the ITO electrodes form a loop, the controller may control the on/off of the switch circuit as needed to control the corresponding ITO electrodes, in this embodiment, the controller is an ECU, wherein the switch circuit may be implemented by using the prior art, which is not described herein again.

As shown in fig. 2 and 3, the black area is the color-changing area of the corresponding electrochromic layer after the ITO electrode is turned on. Taking the first light modulation panel 400 as an example, when the controller controls the switch circuit to turn on a certain ITO electrode or ITO electrodes, the lithium ions stored on the first electrolyte layer 430 are electrically chargedInjected into WO through the first electrolyte layer 430 under the action of a field₃In the lattice voids of the thin film, LiWO is formed_3-xResult in W⁶⁺Is reduced to low-priced W⁵⁺Electrons from W⁶⁺To W⁵⁺The interband transition of (a) absorbs the photon and causes the color change. After the ITO electrode is conducted, the current of the electrified area along the ITO electrode in the horizontal direction is strongest, and the current is weakened along the vertical direction, so that the area of the electrochromic layer corresponding to the conducted ITO electrode is darker in color so as to block incident light, and the area of the electrochromic layer corresponding to the non-conducted ITO electrode is lighter in color or unchanged so as not to block the incident light. In this way, by controlling the on/off of the ITO electrodes on the first light modulation plate 400 and the second light modulation plate 500, the incident light with different height angles can be filtered.

As shown in fig. 4 and 5, if the loops of each ITO electrode are individually controlled, the control and wiring are complicated, and the maintenance and repair are inconvenient, so in this embodiment, each ITO electrode is divided into different groups according to different heights of incident light, and a plurality of loop combinations are formed to meet the filtering requirements of incident light with different heights, for example, as shown in fig. 4, the filtering control schematic diagram of seventeen types of incident light with different heights provided by this embodiment is shown, this embodiment can meet the filtering requirements of incident light with different heights by grouping each ITO electrode into A, B, C, D, E five power supply loops, wherein each power supply loop corresponds to a combination of control manners of ITO electrodes, thereby realizing the filtering of incident light with different heights, and it can be understood that the power supply loops can be set according to actual conditions, for example, the ITO electrodes may be configured to provide more or less power supply loops to meet practical needs. Specifically, for example, 36 strip-shaped ITO electrodes are sequentially disposed on the first transparent conductive layer 410 and the fourth transparent conductive layer 550 from low to high along the height direction of the window glass, as shown in fig. 5, fig. 5 is a partial enlarged view of a power supply loop a in a circle portion in fig. 4, and each ITO electrode is ITO electrode 1 to ITO electrode 36 from low to high.

The ITO electrodes 4 to 6, the ITO electrodes 10 to 12, the ITO electrodes 16 to 18, the ITO electrodes 22 to 24, the ITO electrodes 28 to 30 and the ITO electrodes 34 to 36 of the first transparent conductive layer 410 are connected with an A bus, and the ITO electrodes 4 to 6, the ITO electrodes 10 to 12, the ITO electrodes 16 to 18, the ITO electrodes 22 to 24, the ITO electrodes 28 to 30 and the ITO electrodes 34 to 36 of the fourth transparent conductive layer 550 are also connected with the A bus, so that an A power supply loop is formed. It can be understood that the ITO electrode is connected with the negative electrode of the power supply through an A bus.

On the basis, the ITO electrodes 4 to 6, 10 to 12, 16 to 18, 22 to 24, 28 to 30 and 34 to 36 of the first transparent conductive layer 410 are connected with the B bus, and the ITO electrodes 1, 5 to 7, 11 to 13, 17 to 19, 23 to 25, 29 to 31 and 35 to 36 of the fourth transparent conductive layer 550 are also connected with the B bus, so that a B power supply circuit is formed.

The ITO electrodes 4 to 6, 10 to 12, 16 to 18, 22 to 24, 28 to 30 and 34 to 36 of the first transparent conductive layer 410 are connected with the C bus, and the ITO electrodes 1 to 2, 6 to 8, 12 to 14, 18 to 20, 24 to 26, 30 to 32 and 36 of the fourth transparent conductive layer 550 are also connected with the C bus, so that a C power supply loop is formed.

The ITO electrodes 4 to 6, 10 to 12, 16 to 18, 22 to 24, 28 to 30 and 34 to 36 of the first transparent conductive layer 410 are connected to the D bus, and the ITO electrodes 2 to 4, 8 to 10, 14 to 16, 20 to 22, 26 to 28 and 32 to 34 of the fourth transparent conductive layer 550 are also connected to the D bus, thereby forming a D power supply loop.

The ITO electrodes 4 to 6, 10 to 12, 16 to 18, 22 to 24, 28 to 30 and 34 to 36 of the first transparent conductive layer 410 are connected to the E bus, and the ITO electrodes 3 to 5, 9 to 11, 15 to 17, 21 to 23, 27 to 29 and 33 to 35 of the fourth transparent conductive layer 550 are also connected to the E bus, thereby forming an E power supply circuit.

Under the condition that the control mode of the ITO electrode of the first transparent conductive layer 410 is not changed, the ITO electrode of the fourth transparent conductive layer 550 is controlled according to a preset control mode sequence, that is, the a bus conduction, the B bus conduction, the C bus conduction, the D bus conduction or the E bus conduction is controlled, and under each control mode, the ITO electrode to be conducted of the fourth transparent conductive layer 550 is sequentially moved upwards by one position or n positions, so that the control mode of the ITO electrode of the fourth transparent conductive layer 550 forms a cycle. For example, in this embodiment, on the basis of the E power supply loop, after the to-be-conducted ITO electrode of the fourth transparent conductive layer 550 is moved upward by one position, the control manner is the same as that of the power supply loop a, and by analogy, all the ITO electrodes are connected to the buses a to E according to the above method, so that the filtering of the incident light at different height angles can be realized by only controlling the on/off of the buses a to E. Therefore, under the condition that the height angle of incident light is known, the filtering of the incident light of the specific height angle by the vehicle window glass can be controlled by controlling the on-off of the buses A-E. The control of the controller on the buses A-E can be realized through a predetermined relation table comprising incident lights with different altitude angles and on-off control of the corresponding buses or determined through real-time calculation according to the altitude angles of the incident lights.

As shown in fig. 6, in the present embodiment, the on-off control of the incident light and the corresponding bus line at different heights can be calculated and determined based on the formula tan (θ) (H × n × m ± H × s)/T, where θ is the height angle of the incident light, H is the height of each ITO electrode, and n is the number of ITO electrodes controlled at each time in the current control mode, for example, as shown in fig. 6, the straight line with an arrow in fig. 6 represents the incident light, and in the present embodiment, each time, the on-off control of the incident light and the corresponding bus line is performed at each timeControlling the adjacent 3 groups of ITO electrodes to be switched on or switched off, so that n is 3; m represents that m groups of controlled ITO electrodes are included in the electrodes of the fourth transparent conductive layer 550, that is, m × n, s is an offset and s < n, that is, a position amount of the ITO electrode to be turned on of the fourth transparent conductive layer 550 moves upward when the height angle of incident light is θ, as shown in fig. 6, when the incident angle is θ, the a bus is controlled to be turned on, and 2 groups of controlled ITO electrodes are included in the electrodes of the fourth transparent conductive layer 550, m is 2, and if the incident angle becomes θ₁When the B bus needs to be controlled to be conducted, the position of the electrode to be conducted of the fourth transparent conductive layer 550 needs to be moved upward by one position on the basis of the position of the ITO electrode that is conducted when the a bus is controlled to be conducted, for example, when the a bus is controlled to be conducted, the ITO electrodes 4 to 6 of the fourth transparent conductive layer 550 are conducted, and when the B bus is controlled to be conducted, the ITO electrodes 5 to 7 of the fourth transparent conductive layer 550 are conducted, that is, s is 1. T is the distance between the first electrochromic layer 420 and the first electrochromic layer 420. Thus, because θ, H, and T are known, when the initial control state of the ITO electrode is determined, the ITO electrode to be turned on in the ITO electrode corresponding to the fourth transparent conductive layer 550 is determined, so that on-off control of the bus is determined according to a connection mode of the ITO electrode and the bus, and incident light is filtered according to the height angle of the incident light.
