Description

Technical Field

[0001] The utility model relates to an electrochromic device capable of controlling local color change by partitioning. Background Art

[0002] At present, when road monitoring cameras encounter strong light such as street lamps or car high beams at night, local areas of the monitoring screen may be overexposed. In order to solve the problem of local overexposure of the monitoring screen, some existing road monitoring cameras use electrochromic lenses. When encountering strong light such as street lamps or car high beams, the color of the electrochromic lenses becomes darker and the transmittance is reduced, thereby avoiding strong light exposure and causing local overexposure of the monitoring screen.

[0003] However, the existing electrochromic lenses can only achieve full-surface color change, that is, the entire surface becomes darker or the entire surface fades and becomes lighter, but cannot achieve separate control of color change in local areas. The strong light from street lamps or car high beams will only cause overexposure in local areas of the monitoring screen. When the color of the entire surface of the electrochromic lens becomes darker, the light transmittance is greatly reduced. At this time, the exposure of the area of ​​the monitoring screen that is illuminated by strong light will be reduced, and the area that is not illuminated by strong light will have a large number of noise points due to insufficient light, resulting in a decrease in image clarity. Therefore, the existing electrochromic lenses that can only change color on the entire surface cannot effectively solve the problem of partial overexposure of the monitoring screen caused by strong light from street lamps or high beams on road monitoring cameras. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an electrochromic device with partitioned control of local color change, which can realize the independent control of color change in local areas. When applied to road monitoring cameras, it can effectively solve the problem of local overexposure of monitoring images caused by strong light exposure.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an electrochromic device capable of controlling local color change by partitioning, comprising a first substrate, a second substrate, a first conductive film layer, a second conductive film layer and an electrochromic layer;

[0006] The first substrate and the second substrate are arranged opposite to each other;

[0007] The first conductive film layer is disposed on the end surface of the first substrate facing the second substrate;

[0008] The second conductive film layer is disposed on the end surface of the second substrate facing the first substrate;

[0009] The electrochromic layer is stacked between the first conductive film layer and the second conductive film layer;

[0010] The first conductive film layer has at least two first conductive parts which are arranged in sequence in the transverse direction and are electrically isolated from each other;

[0011] The second conductive film layer has at least two second conductive parts which are arranged in sequence along the longitudinal direction and are electrically isolated from each other;

[0012] The first conductive portion is located on one side of the electrochromic layer, and the second conductive portion is located on the other side of the electrochromic layer. The first conductive portion and the second conductive portion intersect each other and have an overlapping area.

[0013] Further, each of the first conductive parts has an overlapping area with at least one of the second conductive parts;

[0014] Each of the second conductive portions has an overlapping area with at least one of the first conductive portions.

[0015] Furthermore, each of the first conductive portions has an overlapping area with all of the second conductive portions.

[0016] Furthermore, the overlapping area between the first conductive part and the second conductive part is distributed in a matrix shape.

[0017] Furthermore, the first conductive portion and the second conductive portion are both long strip structures, the length direction of the first conductive portion is arranged along the longitudinal direction, and the length direction of the second conductive portion is arranged along the transverse direction.

[0018] Furthermore, a first separation zone is provided between any adjacent first conductive parts in the first conductive film layer;

[0019] A second separation zone is provided between any adjacent second conductive parts in the second conductive film layer.

[0020] Furthermore, first conductive ears corresponding to the first conductive parts are provided on the first substrate, and the first conductive parts extend to the corresponding first conductive ears.

[0021] Furthermore, the second substrate is provided with second conductive ears corresponding to the second conductive parts one by one, and the second conductive parts extend to the corresponding second conductive ears.

[0022] A specific structure of the electrochromic layer is further provided. The electrochromic layer includes a glue frame and an electrochromic material filled inside the glue frame. The first conductive part is located on one side of the electrochromic material, and the second conductive part is located on the other side of the electrochromic material.

[0023] Furthermore, the first substrate and the second substrate are both made of transparent materials, and the first conductive film layer and the second conductive film layer are both ITO film layers.

[0024] After adopting the above technical solution, when in use, power is supplied to at least one first conductive part and at least one second conductive part. At this time, an effective electric field will be formed in the overlapping area formed by the intersection of the energized first conductive part and the energized second conductive part, while no effective electric field will be formed in the overlapping area formed by the intersection of the unenergized first conductive part and the unenergized second conductive part, the overlapping area formed by the intersection of the energized first conductive part and the unenergized second conductive part, and the overlapping area formed by the intersection of the unenergized first conductive part and the energized second conductive part. In the overlapping area where an effective electric field is formed, the electrochromic layer will be colored under the action of the electric field and the color will become darker. In the overlapping area where no effective electric field is formed, the electrochromic layer will not be colored and will maintain a light transparent state. Therefore, after power is supplied to at least one first conductive part and at least one second conductive part, the overlapping area formed by the intersection of the powered-on first conductive part and the powered-on second conductive part will be colored and darker due to the application of voltage, while the color of other areas remains unchanged and remains transparent, thereby achieving local color change; and by supplying power to different first conductive parts and different second conductive parts, the colors of different areas can be darker, thereby achieving independent control of color change in local areas, that is, the color-changing area can be controlled as needed.

[0025] When the electrochromic device with partitioned control for local color change of the embodiment of the present application is applied to a road monitoring camera, when the monitoring screen is partially overexposed due to strong light such as street lamps or car high beams, the corresponding first conductive part and the corresponding second conductive part are energized according to the position of the local overexposure in the monitoring screen, so that the area corresponding to the overexposed position on the electrochromic device is locally and individually discolored, and the color of the area that is locally and individually discolored becomes darker, which can suppress the strong light of street lamps and car high beams, thereby suppressing the local overexposure in the monitoring screen, realizing the local exposure reduction processing of the monitoring screen, and thus improving the monitoring image quality. At the same time, the undiscolored area on the electrochromic device still maintains a light transparent state, and thus will not suppress the transmittance of light, so there will be no problem of unclear picture due to insufficient light. Therefore, the electrochromic device with partitioned control for local color change of the embodiment of the present application is applied to the road monitoring camera to effectively solve the problem of local overexposure of the monitoring screen caused by strong light, and will not cause the phenomenon of unclear picture due to insufficient light.

[0032] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0033] like Figures 1 to 6 As shown, an electrochromic device capable of controlling local color change by partitioning includes a first substrate 1, a second substrate 2, a first conductive film layer 100, a second conductive film layer 200 and an electrochromic layer 300;

[0034] The first substrate 1 and the second substrate 2 are arranged opposite to each other;

[0035] The first conductive film layer 100 is disposed on the end surface of the first substrate 1 facing the second substrate 2;

[0036] The second conductive film layer 200 is disposed on the end surface of the second substrate 2 facing the first substrate 1;

[0037] The electrochromic layer 300 is stacked between the first conductive film layer 100 and the second conductive film layer 200;

[0038] The first conductive film layer 100 has at least two first conductive parts 3 which are arranged in sequence in a transverse direction and are electrically isolated from each other;

[0039] The second conductive film layer 200 has at least two second conductive parts 4 which are arranged in sequence along the longitudinal direction and are electrically isolated from each other;

[0040] The first conductive portion 3 is located on one side of the electrochromic layer 300 , and the second conductive portion 4 is located on the other side of the electrochromic layer 300 . The first conductive portion 3 and the second conductive portion 4 intersect with each other and have an overlapping area 5 .

[0041] Specifically, when in use, power is supplied to at least one first conductive part 3 and at least one second conductive part 4. At this time, an effective electric field is formed in the overlapping region 5 formed by the intersection of the energized first conductive part 3 and the energized second conductive part 4, while no effective electric field is formed in the overlapping region 5 formed by the intersection of the unenergized first conductive part 3 and the unenergized second conductive part 4, the overlapping region 5 formed by the intersection of the energized first conductive part 3 and the unenergized second conductive part 4, and the overlapping region 5 formed by the intersection of the unenergized first conductive part 3 and the energized second conductive part 4. In the overlapping region 5 where an effective electric field is formed, the electrochromic layer 300 will be colored under the action of the electric field and the color will become darker. In the overlapping region 5 where no effective electric field is formed, the electrochromic layer 300 will not be colored and will maintain a light-colored transparent state. Therefore, after power is supplied to at least one first conductive part 3 and at least one second conductive part 4, the overlapping area 5 formed by the intersection of the powered first conductive part 3 and the powered second conductive part 4 will be colored and darkened due to the voltage applied, while the color of other areas remains unchanged and transparent, thus achieving local color change; and by supplying power to different first conductive parts 3 and different second conductive parts 4, the color of different areas can be darkened, thus achieving the independent control of color change in local areas, that is, the color-changing area can be controlled as needed. For example, Figure 1 The middle part shows the individually controlled color change of the local area achieved after power is supplied to the second first conductive part 3 on the left and the second second conductive part 4 below.

[0042] More specifically, when the electrochromic device capable of controlling local color change of the embodiment of the present application is applied to a road monitoring camera, when local overexposure occurs in the monitoring image due to strong light such as street lamps or car high beams, the corresponding first conductive part 3 and the corresponding second conductive part 4 are energized according to the position of the local overexposure in the monitoring image, so that the area corresponding to the overexposed position on the electrochromic device is locally and individually discolored, and the color of the area that is locally and individually discolored becomes darker, which can suppress the strong light of street lamps and car high beams, thereby suppressing the local overexposure in the monitoring image, realizing the local exposure reduction processing of the monitoring image, and thus improving the monitoring image quality. At the same time, the undiscolored area on the electrochromic device still maintains a light transparent state, and thus will not suppress the transmittance of light, so there will be no problem of unclear picture due to insufficient light. Therefore, the electrochromic device capable of controlling local color change of the embodiment of the present application is applied to the road monitoring camera, which can effectively solve the problem of local overexposure of the monitoring image caused by strong light, and will not cause the phenomenon of unclear picture due to insufficient light.

[0043] Specifically, each of the first conductive parts 3 has an overlapping area 5 with at least one of the second conductive parts 4 , and each of the second conductive parts 4 has an overlapping area 5 with at least one of the first conductive parts 3 ; in the present embodiment, each of the first conductive parts 3 has an overlapping area 5 with all of the second conductive parts 4 .

[0044] like Figure 1 As shown, the overlapping area 5 between the first conductive part 3 and the second conductive part 4 is distributed in a matrix shape.

[0045] like Figures 4 to 6 As shown, the first conductive part 3 and the second conductive part 4 are both long strip structures, the length direction of the first conductive part 3 is arranged along the longitudinal direction, and the length direction of the second conductive part 4 is arranged along the transverse direction.

[0046] like Figure 1 , 4 As shown in , 5 and 6, a first separation zone 6 is provided between any adjacent first conductive parts 3 in the first conductive film layer 100;

[0047] A second separation zone 7 is provided between any adjacent second conductive parts 4 in the second conductive film layer 200 .

[0048] Specifically, the first conductive film layer 100 is firstly magnetron sputtered on the first substrate 1, and then laser marked on the first conductive film layer 100 to form the first dividing band 6. The first dividing band 6 separates the first conductive film layer 100 to form at least two first conductive parts 3 electrically isolated from each other.

[0049] More specifically, the second conductive film layer 200 is firstly magnetron sputtered on the second substrate 2, and then laser marked on the second conductive film layer 200 to form the second dividing zone 7. The second dividing zone 7 separates the second conductive film layer 200 to form at least two second conductive parts 4 electrically isolated from each other.

[0050] like Figures 1 to 6 As shown, the first substrate 1 is provided with first conductive ears 8 corresponding to the first conductive parts 3 one by one, and the first conductive parts 3 extend to the corresponding first conductive ears 8; the second substrate 2 is provided with second conductive ears 9 corresponding to the second conductive parts 4 one by one, and the second conductive parts 4 extend to the corresponding second conductive ears 9; specifically, the corresponding first conductive parts 3 can be energized through the first conductive ears 8, and the corresponding second conductive parts 4 can be energized through the second conductive ears 9.

[0051] like Figures 1 to 4As shown, the electrochromic layer 300 may include a plastic frame 10 and an electrochromic material 11 filled inside the plastic frame 10 , the first conductive portion 3 is located on one side of the electrochromic material 11 , and the second conductive portion 4 is located on the other side of the electrochromic material 11 .

[0052] Specifically, the first substrate 1 and the second substrate 2 are both made of transparent materials, and the first conductive film layer 100 and the second conductive film layer 200 are both ITO film layers; in this embodiment, the first substrate 1 and the second substrate 2 can both be glass substrates.

[0053] Specifically, the number of the first conductive parts 3 and the second conductive parts 4 can be three, four, or any number as needed; in the present embodiment, the number of the first conductive parts 3 and the second conductive parts 4 are five, respectively.

[0054] In summary, when in use, power is supplied to at least one first conductive part 3 and at least one second conductive part 4, and an effective electric field is formed in the overlapping region 5 formed by the intersection of the energized first conductive part 3 and the energized second conductive part 4, while no effective electric field is formed in the overlapping region 5 formed by the intersection of the unenergized first conductive part 3 and the unenergized second conductive part 4, the overlapping region 5 formed by the intersection of the energized first conductive part 3 and the unenergized second conductive part 4, and the overlapping region 5 formed by the intersection of the unenergized first conductive part 3 and the energized second conductive part 4. In the overlapping region 5 where an effective electric field is formed, the electrochromic layer 300 will be colored under the action of the electric field and the color will become darker, and in the overlapping region 5 where no effective electric field is formed, the electrochromic layer 300 will not be colored and will maintain a light-colored transparent state. Therefore, after power is supplied to at least one first conductive part 3 and at least one second conductive part 4, the overlapping area 5 formed by the intersection of the powered first conductive part 3 and the powered second conductive part 4 will be colored and darker due to the application of voltage, while the color of other areas remains unchanged and remains transparent, thereby achieving local color change; and, by supplying power to different first conductive parts 3 and different second conductive parts 4, the colors of different areas can be darker, thereby achieving independent control of color change in local areas, that is, the color-changing area can be controlled as needed.

[0055] When the electrochromic device with partitioned control for local color change of the embodiment of the present application is applied to a road monitoring camera, when the monitoring screen is partially overexposed due to strong light such as street lamps or car high beams, the corresponding first conductive part 3 and the corresponding second conductive part 4 are energized according to the position of the local overexposure in the monitoring screen, so that the area corresponding to the overexposed position on the electrochromic device is locally and individually discolored, and the color of the area that is locally and individually discolored becomes darker, which can suppress the strong light of street lamps and car high beams, thereby suppressing the local overexposure in the monitoring screen, realizing the local exposure reduction processing of the monitoring screen, and thus improving the monitoring image quality. At the same time, the undiscolored area on the electrochromic device still maintains a light transparent state, and thus will not suppress the transmittance of light, so there will be no problem of unclear picture due to insufficient light. Therefore, the electrochromic device with partitioned control for local color change of the embodiment of the present application is applied to the road monitoring camera to effectively solve the problem of local overexposure of the monitoring screen caused by strong light, and will not cause the phenomenon of unclear picture due to insufficient light.
