[0031] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate the same or corresponding parts and features.

[0032] Figure 1 A vehicle 10 is shown according to a non-limiting example. The vehicle 10 includes a body 12 supported on a plurality of wheels 16. One or more of the plurality of wheels 16 are steerable. The body 12 partially defines a passenger compartment 20 having a driver seat 23 and a passenger seat 24 located behind an instrument panel 26. The instrument panel 26 may include an infotainment system display 120 and an instrument panel display 130. The infotainment system display 120 is part of an infotainment system that may provide audio and / or visual entertainment and provide information about the vehicle and / or road in audio and / or visual form. As a non-limiting example, the infotainment system display 120 may provide a visual component of the infotainment system, and may include a light source, and may be, for example, a liquid crystal display. The instrument panel display 130 is part of an instrument panel system, and may provide information about the vehicle and / or road in visual and / or audio form. The instrument panel display 130 may provide a visual component of the instrument panel system, and may include a light source, and may be, for example, a liquid crystal display. According to a non-limiting example, the infotainment system display 120 and the instrument panel display 130 may be combined into a single display. The vehicle body 12 also partially defines a prime mover compartment 14 that houses a prime mover. The prime mover can be, for example, an engine, an electric motor, or both an engine and an electric motor in a hybrid configuration. The vehicle body 12 also includes a front door 18 and a rear door 19. A driver's side window 110 is disposed above the driver's side front door 18.

[0033] Figure 2 and Figure 3A passenger compartment 20 of a vehicle 10 according to a non-limiting example is schematically illustrated. Specifically, examples of relative positions of a driver 101, a passenger 102, an infotainment system display 120, and a dashboard display 130 within the passenger compartment 20 are schematically illustrated. The infotainment system display 120 may be positioned longitudinally in front of the driver 101 and the passenger 102 and laterally between the driver 101 and the passenger 102. The dashboard display 130 may be located directly in front of the driver 101. The driver side window 110 is laterally outboard of the driver 101 above the driver side front door 18. In addition, the passenger compartment 20 includes a driver reference position P1 defined at a position where the eyes of the driver 101 may be positioned and a passenger reference position P2 defined at a position where the eyes of the passenger 102 may be positioned. According to one or more embodiments, the driver reference position P1 may be defined as the position of the eyes of an average-sized driver 101 sitting on the driver seat 23, and the passenger reference position P2 may be defined as the position of the eyes of an average-sized passenger 102 sitting on the passenger seat 24. According to one or more embodiments, the driver reference position P1 is disposed right above the driver seat 23 , and the passenger reference position P2 is disposed right above the passenger seat 24 .

[0034] like Figure 3 As shown, infotainment system display 120 includes left edge 123 and right edge 124 , and instrument panel display 130 includes left edge 133 and right edge 134 .

[0035] The infotainment system display 120 and the instrument panel display 130 generally have wide viewing angles, allowing the driver 101 and the passenger 102 to view them from various angles. However, in some vehicles, the wide viewing angles of the infotainment system display 120 and the instrument panel display 130 may cause light therefrom to be incident on the driver's side window 110 and thereby reflected to the driver 101.

[0036] As a non-limiting example, Figure 3 As shown, a light beam 125 irradiated from near the left edge 123 of the infotainment system display 120 may be incident on the driver's side window 110, forming an angle φ with respect to the lateral direction of the vehicle 10. is The light beam 125 may be reflected by the driver's side window 110 to form an angle Φ' with respect to the lateral direction of the vehicle 10 is According to one or more embodiments, the infotainment system display 120 and the driver's side window 110 are substantially perpendicular, so that the angle Φ is , Φ' is According to one or more embodiments, the infotainment system display 120 and the driver's side window 110 are not perpendicular, such that the angle Φ is, Φ' is is different. The reflected light beam 125' can then be incident on the driver reference position P1, so that the driver 101 can see the glare in the driver side window 110. Although Figure 3 The non-limiting example in shows that the light beam 125 irradiated from near the left edge 123 of the infotainment system display 120 causes glare for the driver 101, but light irradiated by different portions of the infotainment system display 120 or the entirety thereof may be reflected by the driver's side window 110 and cause glare for the driver 101.

[0037] For example, Figure 3 As shown, in a non-limiting example, the light beam 135 shines from near the left edge 133 of the instrument panel display 130 and is incident on the driver's side window 110, forming an angle φ relative to the lateral direction of the vehicle 10. ip The light beam 135 is reflected by the driver's side window 110 to form an angle Φ' with respect to the lateral direction of the vehicle 10. ip According to one or more embodiments, the dashboard display 130 and the driver's side window 110 are substantially perpendicular, such that the angle Φ ip , Φ' ip According to one or more embodiments, the dashboard display 130 and the driver's side window 110 are not perpendicular, so that the angle Φ ip , Φ' ip The reflected light beam 135' can then be incident on the driver reference position P1, so that the driver 101 can see the glare in the driver side window 110. Figure 3 The non-limiting example in shows a light beam 135 shining from near the left edge 133 of the instrument panel display 130 causing glare for the driver 101 , but light from different portions of the instrument panel display 130 , or the entirety thereof, may be reflected by the driver's side window 110 and cause glare for the driver 101 .

[0038] Figure 4 A schematic diagram of a passenger compartment 20 is shown according to a non-limiting example. The passenger compartment 20 is similar to Figure 3 , but includes a window glare suppression system in the form of a first micro-louver screen 220 formed on the infotainment system display 120, a first polarizing screen 240 formed on the first micro-louver screen 220, a second micro-louver screen 230 formed on the instrument panel display 130, a second polarizing screen 250 formed on the second micro-louver screen 230, and an anti-reflective coating 210 formed on the inner surface of the driver's side window 110. Although Figure 4A vehicle window glare suppression system including an anti-reflection coating 210, a first micro-louver screen 220, a second micro-louver screen 230, a first polarizing screen 240, and a second polarizing screen 250 employed in combination is shown, but the present disclosure is not limited thereto. For example, the vehicle window glare suppression system may include only one of the anti-reflection coating 210, the first micro-louver screen 220, the second micro-louver screen 230, the first polarizing screen 240, and the second polarizing screen 250, or any combination thereof.

[0039] The anti-reflective coating 210 is a structure that smoothes the boundary between the air in the passenger compartment 20 and the glass forming the driver's side window 110. This smoothing of the boundary can reduce reflections from the driver's side window 110. Applying the anti-reflective coating 210 to the driver's side window 110 can reduce reflections of light from the infotainment system display 120 and / or the instrument panel display 130, which reduces glare for the driver 101. The anti-reflective coating 210 is an example of an anti-reflective structure.

[0040] The first polarization screen 240 and the second polarization screen 250 may be formed of a polarization film that limits the type of waves that can pass therethrough to a specific polarization. According to one or more embodiments, the first polarization screen 240 and the second polarization screen 250 are formed of a polarization film that allows only horizontally polarized light to pass through and limits vertically polarized light. The horizontally polarized light may be P-polarized when reflected by the window 110, and the vertically polarized light may be S-polarized when reflected by the window 110. For air-glass reflection, the P-polarized light causes low reflection at an incident angle below 80 degrees (e.g., 0.2 or less), and causes very low reflection at an incident angle below 70 degrees (e.g., 0.05 or less). In addition, when the incident angle is between about 20 degrees and 80 degrees, the P-polarized light has significantly less reflection than the S-polarized light. Therefore, the light emitted by the infotainment system display 120 and the instrument panel display 130 and polarized by the first polarization screen 240 and the second polarization screen 250 causes a significant reduction in reflection at the driver's side window 110, thereby reducing the glare of the driver 101. Furthermore, the combination of the first polarizing screen 240 and / or the second polarizing screen 250 with the anti-reflective coating 210 on the driver side window 110 may result in a further reduction in glare. The first polarizing screen 240 and the second polarizing screen 250 are examples of polarizing structures.

[0041] According to a non-limiting example, instead of employing the first polarizing screen 240 and / or the second polarizing screen 250, the infotainment system display 120 and / or the instrument panel display 130 may be a liquid crystal display with horizontal polarization built in. That is, the liquid crystal display of the infotainment system display 120 and / or the instrument panel display 130 may be configured to irradiate only horizontally polarized light, which will result in reduced glare from the driver's side window 110.

[0042] Each of the first micro louver screen 220 and the second micro louver screen 230 may be formed of a shielding grid line film that blocks light transmission at a certain range of viewing angles to reduce the viewing angle irradiated therefrom. The viewing angle and orientation of light irradiated from the first micro louver screen 220 and the second micro louver screen 230 may be controlled by the spacing and orientation of the shielding grid lines. The first micro louver screen 220 and the second micro louver screen 230 may be coated or laminated on the infotainment system display 120 and the instrument panel display 130. As a non-limiting example, the first micro louver screen 220 and the second micro louver screen 230 may be formed of a micro louver layer including a plurality of shielding grid lines shaped as a plurality of small baffles that block the outer portion of light in the lateral direction of the vehicle 10, thereby reducing the angular range of light passing therethrough. A plastic or resin layer may be formed on either or both sides of the micro louver layer with an adhesive layer therebetween. In addition, a protective layer may be formed as the outermost layer. The first micro-louver screen 220 and the second micro-louver screen 230 are examples of micro-louver structures.

[0043] Although Figure 4 The first micro blind screen 220 directly disposed on the infotainment system display 120 and the first polarizing screen 240 directly disposed on the first micro blind screen 220, and the second micro blind screen 230 directly disposed on the instrument panel display 130 and the second polarizing screen 250 directly disposed on the second micro blind screen 230 are shown, but the present disclosure is not limited thereto. For example, the first polarizing screen 240 may be directly disposed on the infotainment system display 120, and the first micro blind screen 220 may be directly disposed on the first polarizing screen 240, and / or the second polarizing screen 250 may be directly disposed on the instrument panel display 130, and the second micro blind screen 230 may be directly disposed on the second polarizing screen 250. As another example, only the first micro blind screen 220 or only the first polarizing screen 240 may be disposed on the infotainment system display 120, and / or only the second micro blind screen 230 or only the second polarizing screen 250 may be disposed on the instrument panel display 130.

[0044] Note that, regardless of the order in which the first micro-louver screen 220 and the first polarizing screen 240 are disposed on the infotainment system display 120, the first micro-louver screen 220 and the first polarizing screen 240 are both considered to be disposed on the infotainment system display 120. Furthermore, regardless of the order in which the second micro-louver screen 230 and the second polarizing screen 250 are disposed on the instrument panel display 130, the second micro-louver screen 230 and the second polarizing screen 250 are both considered to be disposed on the instrument panel display 130.

[0045] Figure 5 A schematic diagram of a passenger compartment 20 is shown according to a non-limiting example. Specifically, Figure 5 A non-limiting example of a first micro-louver screen 220 formed on the infotainment system display 120 and a second micro-louver screen 230 formed on the instrument panel display 130 is shown.

[0046] The infotainment system display 120 and the instrument panel display 130 may be configured to irradiate light at a wide angle range in the lateral direction of the vehicle 10. The wide angle light from the infotainment system display 120 is incident on the first micro-louver screen 220, and the first micro-louver screen 220 may reduce the viewing angle range in the lateral direction of the vehicle 10 to a reduced angle range to irradiate reduced angle light 222. The reduced angle range θ of the first micro-louver screen 220 is The outermost beam 223 in the lateral direction of the vehicle 10 may be defined as o1 , 223 o2 The angle formed between the outermost beam 223 o1 , 223 o2 There is a central axis 221 at the center position between them.

[0047] The wide angle light from the instrument panel display 130 is incident on the second micro-louver screen 230, which can reduce the viewing angle range in the lateral direction of the vehicle 10 to a reduced angle range θ ip , to irradiate the reduced angle light 232. The reduced angle range θ of the second micro-louver screen 230 ip The outermost beam 233 in the lateral direction of the vehicle 10 may be defined as o1 , 233 o2 The angle formed between the outermost beam 233 o1 , 233 o2 There is a central axis 231 at the center position between them.

[0048] According to one or more embodiments, the first micro louver screen 220 and the second micro louver screen 230 may be configured such that the reduced angle range θ is ,θ ip According to one or more embodiments, the first micro-louver screen 220 and the second micro-louver screen 230 may be configured such that the reduced angle range θ is ,θ ipFor example, if the infotainment system display 120 is intended to be viewed by both the driver 101 and the passenger 102, while the instrument panel display 130 may be intended to be viewed only by the driver 101, then the reduced angular range θ is Can be greater than the reduced angle range θ ip .

[0049] According to one or more embodiments, the first micro-louver screen 220 and the second micro-louver screen 230 may be configured to form a reduced angular range θ is ,θ ip , so that a portion of the reduced angle light 232 is incident on the driver reference position P1, and a portion of the reduced angle light 222 is incident on both the driver reference position P1 and the passenger reference position P2.

[0050] According to one or more embodiments, the first micro-louver screen 220 and the second micro-louver screen 230 may be configured to form a reduced angular range θ is ,θ ip , so that substantially all of the reduced-angle light 222 , 232 is not incident on the driver-side window 110 or is reflected by the driver-side window 110 so as not to be incident on the driver reference position P1 .

[0051] According to one or more embodiments, the first micro-louver screen 220 and the second micro-louver screen 230 may be configured to form a reduced angular range θ is ,θ ip , so that some of the reduced-angle lights 222 , 232 are not incident on the driver-side window 110 or are not reflected by the driver-side window 110 , so as not to be incident on the driver reference position P1 .

[0052] According to one or more embodiments, the first micro-louver screen 220 and the second micro-louver screen 230 may be configured to form a reduced angular range θ is ,θ ip , so that substantially all of the reduced-angle light 222 , 232 is not incident on the driver's side window 110 , is not reflected by the driver's side window 110 so as not to be incident on the driver reference position P1 , or is incident on the driver's side window 110 at an incident angle with low reflection.

[0053] Figure 5The first micro-louver screen 220 and the second micro-louver screen 230 are shown to be uniformly formed such that the reduced angle light 222, 232 has a central axis 221, 231 aligned with the longitudinal axis of the vehicle. However, according to one or more embodiments, the first micro-louver screen 220 and / or the second micro-louver screen 230 may be non-uniformly formed such that at least a portion of the first micro-louver screen 220 and / or the second micro-louver screen 230 illuminates the reduced angle light 222, 232 having the central axis 221, 231 at an angle to the longitudinal axis. In addition to the variation in the central axis 221, 231, the non-uniformity of the first micro-louver screen 220 and / or the second micro-louver screen 230 may vary with the decreasing angle range θ on the first micro-louver screen 220 and / or the second micro-louver screen 230. is ,θ ip This change may be continuous on the first micro-louver screen 220 and / or the second micro-louver screen 230. According to one or more embodiments, the reduced angle range θ is ,θ ip It may correspond to the viewing angle of the first micro-louver screen 220 and / or the second micro-louver screen 230 .

[0054] Figure 6 A non-limiting example of a second micro-louver screen 230 is shown, which is a non-uniform structure disposed on the instrument panel display 130. A portion of the second micro-louver screen 230 longitudinally aligned with the driver reference position P1 irradiates light 232 with a reduced angle c , the angle of light 232 is reduced c In the lateral direction of the vehicle 10, the outermost beam 233 co1 , 233 co2 The angle θ is reduced between ipc and in the outermost beam 233 aligned with the longitudinal direction of the vehicle 10 co1 , 233 co2 The center position between the central axis 231 c .

[0055] The portion of the second micro-louver screen 230 near the left edge 133 of the instrument panel display 130 illuminates the light 232 at a reduced angle l , the angle of light 232 is reduced l In the lateral direction of the vehicle 10, the outermost beam 233 lo1 , 233 lo2 The angle θ is reduced between ipl , and in the outermost beam 233 lo1 , 233 lo2The center position between the central axis 231 l , the central axis 231 l The angle Ψ is formed with the longitudinal direction of the vehicle 10 ipl As a non-limiting example, the central axis 231 l The central axis 231 may overlap with the driver reference position P1. l It may not overlap with the driver reference position P1.

[0056] As a non-limiting example, the outermost beam 233 lo1 The outermost light beam 233 may be irradiated in a direction having a lateral component in a direction toward the driver reference position P1. lo1 The illumination may be in the longitudinal direction of the vehicle, or in a direction having a lateral component in a direction away from the driver reference position P1.

[0057] The portion of the second micro-louver screen 230 near the right edge 134 of the instrument panel display 130 illuminates the light 232 at a reduced angle r , the angle of light 232 is reduced r In the lateral direction of the vehicle 10, the outermost beam 233 ro1 , 233 ro2 The angle θ is reduced between ipr , and in the outermost beam 233 ro1 , 233 ro2 The center position between the central axis 231 r , the central axis 231 r The angle Ψ is formed with the longitudinal direction of the vehicle 10 ipr As a non-limiting example, the central axis 231 r The central axis 231 may overlap with the driver reference position P1. r It may not overlap with the driver reference position P1.

[0058] As a non-limiting example, the outermost beam 233 ro1 The outermost light beam 233 may be irradiated in a direction having a lateral component in a direction toward the driver reference position P1. ro1 The illumination may be in the longitudinal direction of the vehicle, or in a direction having a lateral component in a direction away from the driver reference position P1.

[0059] Since it may be sufficient for the instrument panel display 130 to be seen only by the driver 101, angling the central axis of the angle-reduced light from the exterior portion toward the driver reference position P1 maintains the vision of the driver 101 while suppressing or preventing the angle-reduced light from being reflected back to the driver 101 by the driver side window 110. Thus, glare from the instrument panel display 130 can be suppressed or prevented.

[0060] Although Figures 5 and 6 A vehicle window glare suppression system is shown having only a first micro-louver screen 220 and a second micro-louver screen 230, but the vehicle window glare suppression system may also include a first polarizing screen 240 formed on the first micro-louver screen 220, a second polarizing screen 250 formed on the second micro-louver screen 230, and / or an anti-reflective coating 210 formed on the inner surface of the driver's side window 110.

[0061] Furthermore, the combination of the first micro-louver screen 220 and the first polarizing screen 240 and / or the combination of the second micro-louver screen 230 and the second polarizing screen 250 may produce unique, unexpected benefits. Although, as described above, the first micro-louver screen 220 and / or the second micro-louver screen 230 may be used to reduce the angular range of light illuminated by the infotainment system display 120 and / or the instrument panel display 130 to reduce glare from the driver's side window, too high an angular reduction may also result in a loss of the desired viewing angle of the infotainment system display 120 and / or the instrument panel display 130 for the driver 101 and / or the passenger 102. As a non-limiting example, by employing the first polarizing screen 240 and / or the second polarizing screen 250 to allow only horizontally polarized light to pass therethrough, the first micro-louver screen 220 and / or the second micro-louver screen 230 may be employed with a smaller reduction in viewing angle.
