Description

[0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2019-0101320, filed on August 19, 2019, which is hereby incorporated by reference for all purposes as if fully set forth herein. Technical Field

[0002] Exemplary embodiments of the invention relate generally to an electronic device, and more particularly, to a wearable electronic device. Background Art

[0003] Wearable electronic devices are electronic devices that can be worn on the user's body and are used for augmented reality or virtual reality technology. Wearable electronic devices used for augmented reality technology allow users to view both virtual graphic images and real objects.

[0004] The above information disclosed in this Background section is only for understanding the background of the inventive concept and therefore it may contain information that does not constitute the prior art. Summary of the invention

[0005] The electronic device and wearable electronic device constructed according to the principles and exemplary embodiments of the invention have improved brightness and / or clearer images. For example, the reflective pattern can be set on multiple layers or surfaces. Therefore, it is possible to increase the amount of light reflected by the reflective pattern, thereby improving the brightness of the image. In addition, since the reflective pattern is set on multiple layers or surfaces, it is possible to increase the area of ​​the image display area. In addition, even when the size of the reflective pattern is reduced to achieve a clear image, the brightness of the image can be compensated by increasing the number of reflective patterns.

[0043] In the following description, for the purpose of explanation, in order to provide a thorough understanding of various exemplary embodiments or embodiments of the invention, many specific details are set forth. "Embodiment" and "implementation" as used herein are interchangeable words, which are non-limiting examples of devices or methods using one or more inventive concepts in the inventive concepts disclosed herein. However, it is obvious that various exemplary embodiments can be practiced without these specific details or with one or more equivalent arrangements. In other examples, in order to avoid unnecessarily obscuring various exemplary embodiments, known structures and devices are shown in block diagram form. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, construction and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0044] Unless otherwise specified, the illustrated exemplary embodiments will be understood as providing exemplary features of varying details of some of the ways in which the inventive concept can be implemented in practice. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions and / or aspects, etc. (hereinafter individually or collectively referred to as "elements") of the various embodiments may be further combined, separated, interchanged and / or rearranged without departing from the inventive concept.

[0045] The use of cross hatching and / or shading in the drawings is generally provided to make the boundaries between adjacent elements clear. Thus, unless otherwise specified, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific material, material properties, size, ratio, commonality between the elements shown, and / or any other characteristics, attributes, properties, etc. of the elements. In addition, in the drawings, the size and relative size of the elements may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments may be implemented differently, the specific process sequence may be performed differently from the described sequence. For example, two continuously described processes may be performed substantially simultaneously or in an order opposite to the described sequence. In addition, the same reference numerals represent the same elements.

[0046] When an element or layer is referred to as being "on", "connected to" or "bonded to" another element or layer, the element or layer may be directly on, directly connected to or bonded to the other element or layer, or there may be an intermediate element or intermediate layer. However, when an element or layer is referred to as being "directly on" another element or layer, "directly connected to" or "directly bonded to" another element or layer, there is no intermediate element or intermediate layer. Other words used to describe the relationship between an element or layer should be interpreted in the same way (for example, "between" and "directly between", "adjacent" and "directly adjacent", "on" and "directly on"). For this reason, the term "connection" may refer to physical connection, electrical connection and / or fluid connection with or without an intermediate element. In addition, the D1 axis, the D2 axis and the D3 axis are not limited to the three axes (such as the x-axis, the y-axis and the z-axis) of the rectangular coordinate system, and may be interpreted in a broader sense. For example, the D1 axis, the D2 axis and the D3 axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purpose of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" may be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ for example. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0047] Although the terms "first", "second", etc. may be used to describe various types of elements herein, these elements should not be limited by these terms. These terms are used to distinguish one element from another element. Therefore, without departing from the disclosed teachings, the first element discussed below may be referred to as the second element.

[0048] For descriptive purposes, spatially relative terms such as "under," "below," "under," "down," "above," "up," "above," "higher," "side" (e.g., as in "sidewall"), etc. may be used herein and thereby describe the relationship of one element to another (other) element as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, elements described as "under" or "beneath" other elements or features would subsequently be positioned as "above" the other elements or features. Thus, the exemplary term "under" can include both above and below orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0049] The term used here is for the purpose of describing a particular embodiment, and is not intended to be a restriction. As used here, unless the context clearly indicates otherwise, the singular form "one", "one (kind / person)" and "the (described)" are also intended to include plural forms. In addition, when the terms "comprise", "include" and variations thereof are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, elements, components and / or their groups, but one or more other features, integral bodies, steps, operations, elements, components and / or their groups are not excluded from existence or addition. It should also be noted that, as used here, the terms "substantially", "approximately (about)" and other similar terms are used as approximate terms rather than terms of degree, and are used to explain the measured values, calculated values ​​and / or the inherent deviations of the provided values ​​that will be recognized by those of ordinary skill in the art.

[0050] Various exemplary embodiments are described herein with reference to cross-sectional illustrations and / or exploded illustrations as schematic illustrations of idealized exemplary embodiments and / or intermediate structures. As such, variations in the shapes of the illustrations, such as those caused by manufacturing techniques and / or tolerances, are expected to occur. Therefore, the exemplary embodiments disclosed herein should not necessarily be interpreted as being limited to the specific illustrated shapes of the regions, but rather include deviations in shapes, such as those caused by manufacturing. In this manner, the regions shown in the accompanying drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device, and are not necessarily intended to be limiting as such.

[0051] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this disclosure is a part. Terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless explicitly defined as such herein.

[0052] Figure 1 is a perspective view showing an exemplary embodiment of an electronic device constructed according to the principles of the invention.

[0053] Reference Figure 1 , the electronic device 1000 may be configured to output an image. For example, the image may be an image of an object in an augmented or virtual reality game or environment. The electronic device 1000 may be configured to allow a user to view real objects in the real world as well as virtual images provided from the electronic device 1000.

[0054] The electronic device 1000 may be a wearable electronic device. Figure 1An example is shown in which the electronic device 1000 has a typical shape of glasses. However, the shape of the electronic device 1000 is not limited to this example. For example, the electronic device 1000 may be provided as a part of various wearable products such as a helmet or sports goggles or any other product that can be supported by a part of the human body.

[0055] The electronic device 1000 may include a light transmitting unit in the form of a transmission portion 100 , a first reflector in the form of a first reflection pattern 200 , a second reflector in the form of a second reflection pattern 300 , a display unit in the form of a display portion 400 , and a combiner in the form of a wearable portion 500 .

[0056] The transmission portion 100 may be formed of or include a material transparent to visible light. This may make it possible to allow a user to view a real object through the transmission portion 100. The transmission portion 100 may be formed of or include at least one of one or more synthetic resins and glass, but the material for the transmission portion 100 is not limited to this example. In some exemplary embodiments, the electronic device 1000 may include a pair of transmission portions 100, but in other exemplary embodiments, the electronic device 1000 may be configured to have only one transmission portion 100.

[0057] The first reflective pattern 200 and the second reflective pattern 300 may be disposed in the transmission part 100. The first reflective pattern 200 and the second reflective pattern 300 may include an optical reflective material. The first reflective pattern 200 and the second reflective pattern 300 may include at least one of a metal and a metal alloy. For example, the first reflective pattern 200 and the second reflective pattern 300 may include a metal (e.g., gold, silver, aluminum) or an alloy of the metal. In the exemplary embodiment shown, the first reflective pattern 200 and the second reflective pattern 300 may include a material having a refractive index different from that of the transmission part 100. In this case, light propagating toward the first reflective pattern 200 and the second reflective pattern 300 may be reflected toward the user (e.g., by total reflection).

[0058] The display portion 400 may be disposed near a portion of the transmission portion 100. For example, the display portion 400 may be disposed on the transmission portion 100, and in at least one exemplary embodiment, the display portion 400 may be disposed adjacent to the transmission portion 100 in the first direction DR1. The transmission portion 100 may include a surface facing a user, and here, the surface may be substantially parallel to the first direction DR1 and a second direction DR2 crossing the first direction DR1 at right angles.

[0059] The first and second reflective patterns 200 and 300 may be arranged on a surface which is a part of the surface of the transmission part 100 and which is inclined with respect to the display part 400 .

[0060] The display portion 400 may be configured to provide light to the first reflective pattern 200 and the second reflective pattern 300. The first reflective pattern 200 and the second reflective pattern 300 may reflect the light provided from the display portion 400 toward a third direction DR3, which may intersect both the first direction DR1 and the second direction DR2 at right angles. The reflected light may constitute a portion of an image to be provided to a user.

[0061] The wearing portion 500 may be combined with the transmission portion 100 and the display portion 400. In some exemplary embodiments, the wearing portion 500 and the display portion 400 may be integrated to form a single object. The wearing portion 500 may have a structure configured to be supported by a body part or may have an outer garment that allows a user to wear it. For example, the wearing portion 500 may have a shape similar to glasses having temples and temples / tip tips to wrap around a portion of the wearer's ear.

[0062] A driving portion that drives the display portion 400 may also be provided in the wearable portion 500. In addition, an additional electronic module (eg, a camera) may be attached to the wearable portion 500.

[0063] In some exemplary embodiments, the electronic device 1000 may be configured to provide a virtual image to the user in a monocular or binocular manner. However, exemplary embodiments are not limited thereto. For example, in a monocular embodiment, the display unit 400 may be disposed only on the transmission unit 100 corresponding to one of the two eyes of the user. In this case, the first reflective pattern 200 and the second reflective pattern 300 may be omitted from the transmission unit 100 on which the display unit 400 is not disposed.

[0064] Figure 2 is a perspective view showing another exemplary embodiment of an electronic device constructed according to the principles of the invention.

[0065] Reference Figure 2 , the electronic device 1000a may include a transmission portion 100a, a first reflection pattern 200a, a second reflection pattern 300a, a display portion 400a, and a wearable portion 500a.

[0066] The display portion 400a may be disposed near a portion of the transmission portion 100a. For example, the display portion 400a may be disposed on a side surface of the transmission portion 100a, and in some exemplary embodiments, the display portion 400a may be adjacent to the transmission portion 100a in the second direction DR2. However, the position of the display portion 400 or 400a may be different from the reference portion 100a. Figure 1 and Figure 2 The position of the description changes variously.

[0067] Figure 3 is a cross-sectional view schematically showing a transmissive portion of an electronic device constructed according to the principles of the invention.

[0068] Reference Figure 3 , the transmissive portion 100 may include an incident surface 110 and an emitting surface 120 that is not parallel to the incident surface 110. The emitting surface 120 may be disposed to face the user's eyeball 2000. For example, the incident surface 110 may be substantially parallel to a plane defined by the second direction DR2 and the third direction DR3, and the emitting surface 120 may be substantially parallel to a plane defined by the first direction DR1 and the second direction DR2.

[0069] The first surface 131 and the second surface 132 may be defined in the transmission portion 100. The first surface 131 and the second surface 132 may be spaced apart from each other. Both the first surface 131 and the second surface 132 may be inclined at the same or different angles with respect to the incident surface 110.

[0070] The reflective patterns 200 and 300 may include a first reflective pattern 200 and a second reflective pattern 300. The first reflective pattern 200 may be disposed on the first surface 131, and the second reflective pattern 300 may be disposed on the second surface 132. Each of the first surface 131 and the second surface 132 may be a cross section (i.e., an imaginary surface) in the transmission portion 100. Hereinafter, the imaginary surface on which the first reflective pattern 200 is disposed will be referred to as the first surface 131, and the imaginary surface on which the second reflective pattern 300 is disposed will be referred to as the second surface 132.

[0071] The shortest distance between the first surface 131 and the incident surface 110 may be smaller than the shortest distance between the second surface 132 and the incident surface 110. In addition, the maximum distance between the first surface 131 and the incident surface 110 may be smaller than the shortest distance between the second surface 132 and the incident surface 110. In the illustrated exemplary embodiment, all of the distances 201-L, 202-L, and 203-L between the first reflection pattern 200 and the incident surface 110 may be smaller than all of the distances 301-L, 302-L, and 303-L between the second reflection pattern 300 and the incident surface 110. Therefore, when viewed through the emission surface 120, the first reflection pattern 200 and the second reflection pattern 300 may be offset from each other, e.g., partially or completely non-overlapping. Figure 3 An embodiment is shown in which the first reflective pattern 200 and the second reflective pattern 300 do not overlap at all.

[0072] Unlike the illustrated exemplary embodiment of the invention, in the case where the reflective patterns 200 and 300 are disposed on the same surface, the more reflective patterns 200 and 300 are disposed, the thicker the transmissive portion 100 is. This may result in Figure 1 The weight of the electronic device 1000 increases. According to some exemplary embodiments, the reflective patterns 200 and 300 may be provided on a plurality of surfaces or layers. This may make it possible to increase the number of reflective patterns 200 and 300 provided in the transmission portion 100 without increasing the thickness of the transmission portion 100. Therefore, it may be possible to increase the amount of light reflected by the reflective patterns 200 and 300, thereby improving the brightness of the image. In addition, in some exemplary embodiments in which the brightness of the image is improved, it may be possible to reduce the size of each of the reflective patterns 200 and 300. If the size of the reflective patterns 200 and 300 is reduced, the user may view the virtual image more clearly due to the pinhole effect.

[0073] The display unit 400 may face the incident surface 110. The display unit 400 may include a display panel 410 and an optical unit 420. The display panel 410 may provide light constituting an image to the optical unit 420. The optical unit 420 may be configured to control the path of the light provided from the display panel 410. The optical unit 420 may include a concave lens, a convex lens, or a combination of a convex lens and a concave lens. In some exemplary embodiments, the optical unit 420 may be omitted. In some exemplary embodiments, the optical unit 420 and the display panel 410 may be provided as a single member.

[0074] Figure 4 It is shown by Figure 3 A plan view of an exemplary embodiment of a first reflection pattern and a second reflection pattern viewed from an incident surface of an electronic device.

[0075] Figure 4 The first reflection pattern 200 and the second reflection pattern 300 viewed through the incident surface 110 are shown. Figure 4 An exemplary arrangement of the first reflection pattern 200 and the second reflection pattern 300 viewed through the incident surface 110 is described in more detail.

[0076] The first reflective pattern 200 and the second reflective pattern 300 may not overlap each other at all. The first reflective pattern 200 and the second reflective pattern 300 may be spaced apart from each other. The first reflective pattern 200 may be arranged to be spaced apart from each other in the second direction DR2 and the third direction DR3, and the second reflective pattern 300 may also be arranged to be spaced apart from each other in the second direction DR2 and the third direction DR3. Figure 4 An example is shown in which fifteen first reflection patterns 200 and twelve second reflection patterns 300 are provided, but the number of the first reflection patterns 200 and the second reflection patterns 300 is not limited to this example.

[0077] The second reflection patterns 300 may be disposed, for example, in a row in the space 301 between the first reflection patterns 200. For example, the first reflection patterns 200 and the second reflection patterns 300 may be alternately arranged in the first region 101. The first region 101 may be a region defined by a boundary surrounding the outermost reflection patterns of the first reflection patterns 200 and the second reflection patterns 300. The first region 101 may also be Figure 4 Corresponding to the area A1 in .

[0078] Each of the first reflection pattern 200 and the second reflection pattern 300 may have a substantially circular or substantially elliptical shape. However, exemplary embodiments are not limited to this example. For example, each or at least one of the first reflection pattern 200 and the second reflection pattern 300 may have a substantially polygonal shape, and the shape of the first reflection pattern 200 may be different from the shape of the second reflection pattern 300. In some exemplary embodiments, the size of the first reflection pattern 200 may be substantially equal to the size of the second reflection pattern 300. The first reflection pattern 200 may have a first diameter 20, and the second reflection pattern 300 may have a second diameter 30 equal to the first diameter 20. For example, the first diameter 20 and the second diameter 30 may be in the range of about 0.1 mm to about 2 mm.

[0079] The smaller the first diameter 20 and the second diameter 30 are, the less the amount of light reflected from the first reflection pattern 200 and the second reflection pattern 300 is. However, due to the pinhole effect, the reduction of the first diameter 20 and the second diameter 30 can allow the user to view the virtual image more clearly. The larger the first diameter 20 and the second diameter 30 are, the blurrier the image provided from the display portion 400 is. However, the increase of the first diameter 20 and the second diameter 30 can increase the amount of light reflected from the first reflection pattern 200 and the second reflection pattern 300, which can make it possible to improve the brightness properties of the image. According to some exemplary embodiments, the first diameter 20 and the second diameter 30 can be selected in consideration of the effects described above.

[0080] Figure 5 It is shown by Figure 3 FIG. 1 is a plan view of another exemplary embodiment of a first reflection pattern and a second reflection pattern viewed from an emission surface of an electronic device.

[0081] Figure 5 The first reflection pattern 200 and the second reflection pattern 300 viewed through the emitting surface 120 are shown. Figure 5 An exemplary arrangement of the first reflection pattern 200 and the second reflection pattern 300 viewed through the emission surface 120 is described in more detail.

[0082] The first reflective pattern 200 and the second reflective pattern 300 may not overlap each other at all. The first reflective pattern 200 and the second reflective pattern 300 may be spaced apart from each other. The first reflective pattern 200 may be arranged to be spaced apart from each other in the second direction DR2 and the first direction DR1, and the second reflective pattern 300 may also be arranged to be spaced apart from each other in the second direction DR2 and the first direction DR1.

[0083] All of the first reflective patterns 200 may be spaced apart from all of the second reflective patterns 300 in the first direction DR1. For example, the second region 102 provided with the first reflective patterns 200 may be adjacent to the third region 103 provided with the second reflective patterns 300 in the first direction DR1, but the second region 102 and the third region 103 may not overlap each other at all.

[0084] The second region 102 may be a region defined by a boundary surrounding the outermost reflection pattern in the first reflection pattern 200. The third region 103 may be a region defined by a boundary surrounding the outermost reflection pattern in the second reflection pattern 300. The sum of the area of ​​the second region 102 and the area of ​​the third region 103 may be compared to the reference region 104. Figure 4 The area of ​​the first region 101 is described as being large. In other words, the area A1 of the first region 101 may be smaller than the sum A2 of the area of ​​the second region 102 and the area of ​​the third region 103 .

[0085] According to some exemplary embodiments, the density of the first and second reflection patterns 200 and 300 observed through the emission surface 120 may be lower than the density of the first and second reflection patterns 200 and 300 observed through the incident surface 110. Therefore, the user may easily view a real object through an area between the first and second reflection patterns 200 and 300.

[0086] Figure 6 is a plan view of another exemplary embodiment of a first reflective pattern and a second reflective pattern of an electronic device constructed according to the principles of the invention.

[0087] Figure 6 The first reflection pattern 210 and the second reflection pattern 310 viewed through the incident surface 110 are shown. Figure 6 An exemplary arrangement of the first reflection patterns 210 and the second reflection patterns 310 viewed through the incident surface 110 is described in more detail.

[0088] Reference Figure 6, the size of the first reflection pattern 210 may be different from the size of the second reflection pattern 310. For example, the first diameter 21 of the first reflection pattern 210 may be larger than the second diameter 31 of the second reflection pattern 310. When viewed through the incident surface 110, the second reflection pattern 310 may be identified by the area between the first reflection patterns 210. In other words, by adjusting the sizes of the first reflection pattern 210 and the second reflection pattern 310, the first reflection pattern 210 may not overlap with the second reflection pattern 310. Therefore, the first reflection pattern 210 and the second reflection pattern 310 may be visible from the display portion 400 (e.g., see Figure 1 ) receives light.

[0089] Figure 7 is a plan view of yet another exemplary embodiment of a first reflective pattern and a second reflective pattern of an electronic device constructed according to the principles of the invention.

[0090] Figure 7 The first reflection pattern 220 and the second reflection pattern 320 viewed through the incident surface 110 are shown. Figure 7 An exemplary arrangement of the first reflection patterns 220 and the second reflection patterns 320 viewed through the incident surface 110 is described in more detail.

[0091] Reference Figure 7 The first reflective pattern 220 may include a first pattern 221 , a second pattern 222 , and a third pattern 223 . The second reflective pattern 320 may include a fourth pattern 321 , a fifth pattern 322 , and a sixth pattern 323 .

[0092] The first pattern 221, the second pattern 222, and the third pattern 223 may be sequentially arranged in the second direction DR2, and the fourth pattern 321, the fifth pattern 322, and the sixth pattern 323 may be sequentially arranged in the second direction DR2. The first pattern 221 and the third pattern 223 may be spaced apart from each other, with the second pattern 222 interposed therebetween, and the fourth pattern 321 and the sixth pattern 323 may be spaced apart from each other, with the fifth pattern 322 interposed therebetween. For example, the first outer region 100A1, the central region 100C, and the second outer region 100A2 may be sequentially defined in the incident surface 110 in the second direction DR2. The first pattern 221 and the fourth pattern 321 may be disposed in the first outer region 100A1, the second pattern 222 and the fifth pattern 322 may be disposed in the central region 100C, and the third pattern 223 and the sixth pattern 323 may be disposed in the second outer region 100A2.

[0093] The size of the first pattern 221 may be substantially the same as that of the third pattern 223 and may be larger than that of the second pattern 222. In addition, the size of the fourth pattern 321 may be substantially the same as that of the sixth pattern 323 and may be larger than that of the fifth pattern 322.

[0094] like Figure 3 As shown in FIG. 4 , the display unit 400 may include an optical unit 420. The spherical aberration phenomenon may occur due to the lens in the optical unit 420. According to some exemplary embodiments, by adjusting the size of the first reflective pattern 220 and the size of the second reflective pattern 320, it may be possible to compensate for the distortion of the image caused by the spherical aberration phenomenon. For example, from the display panel 410 (e.g., see Figure 3 ) The size of the image outputted in the outer area may be smaller than that in the central area. In this case, the first pattern 221, the third pattern 223, the fourth pattern 321, and the sixth pattern 323 arranged in the outer areas 100A1 and 100A2 may be designed to have a larger size than the second pattern 222 and the fifth pattern 322 arranged in the central area 100C to prevent the image distortion problem.

[0095] Figure 8 is a plan view of yet another exemplary embodiment of a first reflective pattern and a second reflective pattern of an electronic device constructed according to the principles of the invention.

[0096] Figure 8 The first reflection pattern 230 and the second reflection pattern 330 viewed through the incident surface 110 are shown. Figure 8 An exemplary arrangement of the first reflection patterns 230 and the second reflection patterns 330 viewed through the incident surface 110 is described in more detail.

[0097] Reference Figure 8 The first reflective pattern 230 may include a first pattern 231 , a second pattern 232 , and a third pattern 233 . The second reflective pattern 330 may include a fourth pattern 331 , a fifth pattern 332 , and a sixth pattern 333 .

[0098] The first pattern 231 and the third pattern 233 may be spaced apart from each other with the second pattern 232 interposed therebetween, and the fourth pattern 331 and the sixth pattern 333 may be spaced apart from each other with the fifth pattern 332 interposed therebetween.

[0099] The size of the first pattern 231 may be substantially the same as that of the third pattern 233 and may be smaller than that of the second pattern 232. In addition, the size of the fourth pattern 331 may be substantially the same as that of the sixth pattern 333 and may be smaller than that of the fifth pattern 332.

[0100] From the display unit 400 (for example, see Figure 3 ) The size of the image outputted in the outer area will be larger than that in the central area. In this case, the first pattern 231, the third pattern 233, the fourth pattern 331 and the sixth pattern 333 arranged in the outer areas 100A1 and 100A2 can be designed to have a smaller size than the second pattern 232 and the fifth pattern 332 arranged in the central area 100C to prevent the image distortion problem.

[0101] Fig. 9 is a cross-sectional view schematically illustrating another exemplary embodiment of an electronic device constructed according to the principles of the invention.

[0102] Reference Fig. 9 , a first surface 131, a second surface 132, and a third surface 133 may be defined in the transmission portion 100. The first surface 131, the second surface 132, and the third surface 133 may be spaced apart from each other. All of the first surface 131, the second surface 132, and the third surface 133 may be inclined relative to the incident surface 110 at the same or different angles. In addition, all of the first surface 131, the second surface 132, and the third surface 133 may be spaced apart from the incident surface 110. For example, the third surface 133, the first surface 131, and the second surface 132 may be sequentially disposed in a direction away from the incident surface 110.

[0103] The first reflection pattern 240 may be disposed on the first surface 131 , the second reflection pattern 340 may be disposed on the second surface 132 , and the third reflection pattern 600 may be disposed on the third surface 133 .

[0104] Fig.10 is through Fig. 9 A plan view of yet another exemplary embodiment of a first reflection pattern, a second reflection pattern, and a third reflection pattern viewed from an incident surface of an electronic device.

[0105] Fig.10 The image viewed through the incident surface 110 is shown. Fig. 9 The first reflection pattern 240, the second reflection pattern 340 and the third reflection pattern 600 are shown in FIG. Fig.10 , the first reflective pattern 240, the second reflective pattern 340, and the third reflective pattern 600 may not overlap each other.

[0106] The second reflective patterns 340 may be disposed in a space between the first reflective patterns 240. In other words, the first reflective patterns 240 and the second reflective patterns 340 may be alternately arranged in a specific region.

[0107] The third reflective pattern 600 may include a third first pattern 610 and a third second pattern 620. The third first pattern 610 may be some of the third reflective pattern 600, and the third second pattern 620 may be the remaining portion of the third reflective pattern 600. The third first pattern 610 and the third second pattern 620 may be spaced apart from each other, with the first reflective pattern 240 and the second reflective pattern 340 interposed therebetween. According to some exemplary embodiments, since the third reflective pattern 600 is additionally provided, the area of ​​the image display region may be increased.

[0108] Fig.11 It is shown by Fig. 9 A plan view of a first reflection pattern, a second reflection pattern, and a third reflection pattern viewed from an emission surface of an electronic device.

[0109] Fig.11 The view through the emitting surface 120 is shown. Fig. 9 The first reflection pattern 240, the second reflection pattern 340 and the third reflection pattern 600 are shown in FIG. Fig.11 The density of the first reflection pattern 240, the second reflection pattern 340, and the third reflection pattern 600 viewed through the emission surface 120 may be greater than that viewed through the incident surface 110 (eg, Fig.10 ) The density of the first reflection pattern 240, the second reflection pattern 340, and the third reflection pattern 600 viewed by the user is small. Therefore, the user can easily view the real object through the area between the first reflection pattern 240, the second reflection pattern 340, and the third reflection pattern 600.

[0110] Fig.12 is a perspective view of an exemplary embodiment of a portion of an electronic device constructed according to the principles of the invention.

[0111] Fig.12 The first surface 131 and the first reflective pattern 200 disposed on the first surface 131 are exemplarily shown. Fig.12 , the first surface 131 may be substantially parallel to a flat surface or plane defined by the direction DRa and the direction DRb. In other words, the first surface 131 may be a substantially flat surface. The first reflective pattern 200 may be arranged on the first surface 131 and in the direction DRa and the direction DRb.

[0112] Fig.13 is a perspective view of another exemplary embodiment of a portion of an electronic device constructed according to the principles of the invention.

[0113] Fig.13 The first surface 131c and the first reflective pattern 200c disposed on the first surface 131c are exemplarily shown. Fig.13, the first surface 131c may have a shape that is generally curved relative to a plane defined by the direction DRa and the direction DRb. In other words, the first surface 131c may be a curved surface. The first surface 131c may be a generally curved surface with a finite radius of curvature. The first surface 131c may have the same radius of curvature in all directions, but in some exemplary embodiments, the first surface 131c may have a plurality of radii of curvature.

[0114] Fig.14 is a cross-sectional view schematically illustrating another exemplary embodiment of an electronic device constructed according to the principles of the invention.

[0115] Reference Fig.14 , the first surface 131-1 and the second surface 132-1 may be defined in the transmission portion 100. All of the first surface 131-1 and the second surface 132-1 may be spaced apart from the incident surface 110. The first surface 131-1 may be defined between the second surface 132-1 and the incident surface 110.

[0116] The shortest distance between the first surface 131-1 and the incident surface 110 may be smaller than the shortest distance between the second surface 132-1 and the incident surface 110. In addition, the maximum distance between the first surface 131-1 and the incident surface 110 may be smaller than the shortest distance between the second surface 132-1 and the incident surface 110. In this case, all distances between the first reflection pattern 200 and the incident surface 110 may be smaller than all distances between the second reflection pattern 300 and the incident surface 110. Therefore, when viewed through the emission surface 120, the first reflection pattern 200 and the second reflection pattern 300 may not overlap each other.

[0117] Each of the first surface 131-1 and the second surface 132-1 may be inclined at an angle relative to the incident surface 110. For example, the first surface 131-1 may be inclined at a first angle 131a relative to the incident surface 110, and the second surface 132-1 may be inclined at a second angle 132a relative to the incident surface 110. The first angle 131a and the second angle 132a may be different from each other. For example, the first angle 131a may be greater than the second angle 132a. However, exemplary embodiments are not limited to this example, and in at least some exemplary embodiments, the first angle 131a may be smaller than the second angle 132a.

[0118] According to the principles and exemplary embodiments of the invention, the reflective pattern can be arranged on multiple layers or surfaces. Therefore, it is possible to increase the amount of light reflected by the reflective pattern, thereby improving the brightness of the image. In addition, since the reflective pattern is arranged on multiple layers or surfaces, it is possible to increase the area of ​​the image display area. In addition, even when the size of the reflective pattern is reduced to achieve a clear image, the brightness of the image can be compensated by increasing the number of reflective patterns.

[0119] Although certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Therefore, the inventive concept is not limited to such embodiments, but to the broader scope of the claims and various obvious modifications and equivalent arrangements as will be apparent to those of ordinary skill in the art.
