Description

Technical Field

[0001] The disclosure relates to an optical device. Background Technology

[0002] Augmented reality (AR) refers to the technology of overlaying virtual images onto real images as seen by the user's eyes and displaying them as a single image. The virtual images can be text or graphics, while the real images can be information about real objects observed within the device's field of view. AR can be implemented using head-mounted displays (HMDs), head-up displays (HUDs), and the like.

[0003] Optical devices for providing augmented reality may include optical components that provide a virtual image displayed on a display device to the user's eyes by altering the optical path of the virtual image. The optical device may also include a condenser for focusing the virtual image of the display device onto the optical component. Due to the small distance between the display device and the optical component, the thickness of the condenser can be increased to enhance refractive power. Optical devices for providing augmented reality can be provided in the form of eyeglasses, making them easy for users to carry and easily put on or take off. However, if the condenser is thick, it may be difficult to implement the optical device in the form of eyeglasses. Summary of the Invention

[0037] Embodiments of the inventive concept will be described in more detail below with reference to the accompanying drawings. Throughout the drawings, the same reference numerals may refer to the same elements. In the drawings, the thickness, proportions, and dimensions of the components are exaggerated for the purpose of effectively describing the technical content.

[0038] It will be understood that when a component (such as a membrane, region, layer, or element) is referred to as being "on," "connected to," "bonded to," or "adjacent to" another component, the component may be directly on, directly connected to, directly bonded to, or directly adjacent to the other component, or there may be intermediate components present. It will also be understood that when a component is referred to as being "between" two components, the component may be the only component between the two components, or there may be one or more intermediate components present. It will also be understood that when a component is referred to as "covering" another component, the component may be the only component covering the other component, or one or more intermediate components may also cover the other component. Other terms used to describe relationships between elements can be interpreted in the same way.

[0039] It will also be understood that when the terms “comprising,” “having,” “possessing,” “including,” and / or variations thereof are used in this specification, the terms are intended to indicate the presence of the stated features, areas, integrals, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, areas, integrals, steps, operations, elements, components, and / or groups thereof.

[0040] It will also be understood that, unless the context clearly indicates otherwise, the description of a feature or aspect within each embodiment may be used for other similar features or aspects in other embodiments.

[0041] As used herein, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well. For example, unless the context clearly indicates otherwise, “element” has the same meaning as “at least one element.” The phrase “at least one” will not be interpreted as limited to “a” or “an.” “Or” means “and / or”.

[0042] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, without departing from the teaching herein, the first “element,” “component,” “region,” “layer,” or “part” discussed below may be designated as a second element, component, region, layer, or part.

[0043] For ease of description, spatial relative terms (such as "below," "under," "below," "below," "above," "above," etc.) are used here to describe the relationship between one element or feature and another (other) element or feature as shown in the figure. It will be understood that, in addition to the orientation depicted in the figure, spatial relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figure were flipped, an element described as "below" or "below" or "below" another element or feature would subsequently be positioned "above" said other element or feature. Therefore, the terms "below" and "below" can encompass both above and below orientations.

[0044] Figure 1 This is a perspective view of the optical device 1 according to an embodiment. Figure 2 This is an exploded perspective view of the optical device 1 according to an embodiment.

[0045] Reference Figure 1 and Figure 2 The augmented reality providing device (also referred to as an optical device) 1 according to the embodiment includes a support frame 20, a right lens frame 21, a left lens frame 22, a first temple 31, a second temple 32, a right lens 110, a left lens 120, a first display device 210, a second display device 220, a right condenser 310, a left condenser 320, a right reflector 410, and a left reflector 420.

[0046] In the specification, the first direction (e.g., the X-axis direction) can be the width direction of each of the right lens 110 and the left lens 120, the second direction (e.g., the Y-axis direction) can be the thickness direction of each of the right lens 110 and the left lens 120, and the third direction (e.g., the Z-axis direction) can be the height direction of each of the right lens 110 and the left lens 120.

[0047] The support frame 20, together with the right lens frame 21 and the left lens frame 22, supports the right lens 110 and the left lens 120. The right lens 110 can be surrounded by the support frame 20 and the right lens frame 21. The left lens 120 can be surrounded by the support frame 20 and the left lens frame 22.

[0048] The support frame 20 can be disposed on the upper surface of the right lens 110 and the upper surface of the left lens 120. The support frame 20 can extend in a first direction (X-axis direction).

[0049] The right lens frame 21 can be disposed on the left, lower, and right surfaces of the right lens 110. The right lens frame 21 can be physically coupled to the support frame 20. The left lens frame 22 can be disposed on the left, lower, and right surfaces of the left lens 120. The left lens frame 22 can be physically coupled to the support frame 20. Each of the right lens frame 21 and the left lens frame 22 may include a nasal support.

[0050] Despite Figure 2 The middle support frame 20, the right lens frame 21, and the left lens frame 22 are formed separately and then joined together, but the disclosure is not limited thereto. The support frame 20, the right lens frame 21, and the left lens frame 22 may also be formed integrally.

[0051] The first temple 31 can be fixed to the right end of the lower surface of the support frame 20. The second temple 32 can be fixed to the left end of the lower surface of the support frame 20. Each of the first temple 31 and the second temple 32 can be fixed to the support frame 20 by means of a fixing member (such as a screw).

[0052] Each of the support frame 20, right lens frame 21, left lens frame 22, first temple 31, and second temple 32 may include plastic, metal, or both plastic and metal. The right lens frame 21 and left lens frame 22 may be omitted.

[0053] Each of the right lens 110 and the left lens 120 can be made of glass or plastic, and can be transparent or translucent. Therefore, the user can see a realistic image through the right lens 110 and the left lens 120. Considering the user's vision, the right lens 110 and the left lens 120 can have refractive power.

[0054] Each of the right lens 110 and the left lens 120 can be shaped like a cuboid composed of a first surface, a second surface, and first to fourth side surfaces that are quadrilaterals. However, the disclosure is not limited thereto. Each of the right lens 110 and the left lens 120 can also be shaped like a polyhedron composed of a first surface, a second surface, and side surfaces that are polygons other than quadrilaterals. Each of the right lens 110 and the left lens 120 can be shaped like a cylinder, an elliptical cylinder, a semi-cylinder, a semi-elliptical cylinder, an extruded cylinder, or an extruded semi-cylinder, other than a polyhedron. Extruded cylinders and extruded semi-cylinders refer to cylinders and semi-cylinders with non-uniform diameters.

[0055] The first surface of the right lens 110 may be the right eye RE facing the user (see...) Figure 7 The second surface of the right lens 110 is the outer surface of the right lens 110 from which the light from the first display device 210 passes through the right reflector 410.

[0056] The first surface of the left lens 120 may be the surface facing the user's left eye, and is the exit surface from which light from the second display device 220 passes through the left reflector 420 of the left lens 120. The second surface of the left lens 120 may be the outer surface of the left lens 120.

[0057] Each of the right reflector 410 and the left reflector 420 can be a small reflector (such as a pinmirror). Each of the right reflector 410 and the left reflector 420 can be smaller than the pupil of the right eye RE or the left eye. For example, the maximum width of each of the right reflector 410 and the left reflector 420 can be in the range of tens to hundreds of micrometers. Because the user's pupil is focused on the real image, it is difficult to distinguish the right reflector 410 and the left reflector 420.

[0058] Although each of the right reflector 410 and the left reflector 420 is in Figure 1 and Figure 2 The right reflector 410 and the left reflector 420 may each have a circular planar shape, but the disclosure is not limited to this. Each of them may also have an elliptical or polygonal planar shape in addition to a circular planar shape. Although in Figure 1 and Figure 2 In the middle, three right reflectors 410 are disposed in the right lens 110 and three left reflectors 420 are disposed in the left lens 120, but the number of right reflectors 410 disposed in the right lens 110 and the number of left reflectors 420 disposed in the left lens 120 are not limited thereto.

[0059] The right reflector 410 may include a first right reflector 411, a second right reflector 412, and a third right reflector 413. The first right reflector 411, the second right reflector 412, and the third right reflector 413 may be disposed in the right lens 110. The first right reflector 411, the second right reflector 412, and the third right reflector 413 can reflect the image displayed on the first display device 210 to the user's right eye RE.

[0060] The left reflector 420 may include a first left reflector 421, a second left reflector 422, and a third left reflector 423. The first left reflector 421, the second left reflector 422, and the third left reflector 423 may be disposed in the left lens 120. The first left reflector 421, the second left reflector 422, and the third left reflector 423 can reflect the image displayed on the second display device 220 to the user's left eye.

[0061] A first display device 210 may be disposed on a first side surface of the right lens 110, and a second display device 220 may be disposed on a first side surface of the left lens 120. Each of the first display device 210 and the second display device 220 is used to realize a virtual image for augmented reality. The first display device 210 may include a first display panel 211 and a first circuit board 212. The second display device 220 may include a second display panel 221 and a second circuit board 222.

[0062] Each of the first display panel 211 and the second display panel 221 may be an organic light-emitting display panel or a quantum dot light-emitting display panel including quantum dots. Each of the first display panel 211 and the second display panel 221 may be bent or folded due to its flexibility.

[0063] A first circuit board 212 can be attached to an end of a first display panel 211. The first display panel 211 can receive digital video data from an external source and power from an external power supply unit via the first circuit board 212. A second circuit board 222 can be attached to an end of a second display panel 221. The second display panel 221 can receive digital video data from an external source and power from an external power supply unit via the second circuit board 222. Both the first circuit board 212 and the second circuit board 222 can be flexible printed circuit boards, and therefore can be bent or folded.

[0064] A power supply unit for supplying power to the first display device 210 and the second display device 220 can be embedded in either the first temple 31 or the second temple 32. A first cable for connecting the first circuit board 212 to the power supply unit and a second cable for connecting the second circuit board 222 to the power supply unit may be additionally provided. When the power supply unit is embedded in the second temple 32, the first cable can extend into the second temple 32. The first cable may be longer than the second cable.

[0065] The right condenser 310 may be disposed between the first display device 210 and the first side surface of the right lens 110, and the left condenser 320 may be disposed between the second display device 220 and the first side surface of the left lens 120. The right condenser 310 may include a first right condenser 311, a second right condenser 312, and a third right condenser 313. The left condenser 320 may include a first left condenser 321, a second left condenser 322, and a third left condenser 323.

[0066] Each of the right condensers 311 to 313 and the left condensers 321 to 323 may include at least one convex lens. As the number of convex lenses included in each of the right condensers 311 to 313 and the left condensers 321 to 323 increases, the refractive power can increase, thereby enhancing the light focusing effect. However, the length of each of the right condensers 311 to 313 and the left condensers 321 to 323 in the third direction (Z-axis direction) increases.

[0067] The right condensers 311 to 313 may each include a first right convex lens 311a to 313a and a second right convex lens 311b to 313b. The second right convex lenses 311b to 313b may be disposed between the first right convex lenses 311a to 313a and the first side surface of the right lens 110.

[0068] The first right-hand convex lenses 311a to 313a may convex in the direction in which the second right-hand convex lenses 311b to 313b are disposed. For example, the first right-hand convex lenses 311a to 313a may convex downward. The second right-hand convex lenses 311b to 313b may convex in the direction in which the first right-hand convex lenses 311a to 313a are disposed. For example, the second right-hand convex lenses 311b to 313b may convex upward. However, the convex shapes of the first right-hand convex lenses 311a to 313a and the second right-hand convex lenses 311b to 313b are not limited to these shapes. Figure 2 The shape shown in the image.

[0069] The left condensers 321 to 323 may each include a first left convex lens 321a to 323a and a second left convex lens 321b to 323b. The second left convex lenses 321b to 323b may be disposed between the first left convex lenses 321a to 323a and the first side surface of the left lens 120.

[0070] The first left convex lenses 321a to 323a may convex in the direction in which the second left convex lenses 321b to 323b are disposed. For example, the first left convex lenses 321a to 323a may convex downward. The second left convex lenses 321b to 323b may convex in the direction in which the first left convex lenses 321a to 323a are disposed. For example, the second left convex lenses 321b to 323b may convex upward. However, the convex shape of the first left convex lenses 321a to 323a and the convex shape of the second left convex lenses 321b to 323b are not limited to these shapes. Figure 2 The shape shown in the image.

[0071] Figure 3 It shows in detail Figure 2 An exploded perspective view of an example of the right lens 110 and the right reflector 410. Figure 4 It shows in detail Figure 2 A schematic side view of an example of the right lens 110 and the right reflector 410. Figure 4 This is a schematic right-side view as seen from the right-side surface of the right lens 110.

[0072] Reference Figure 3 and Figure 4 The right lens 110 may include a first lens unit 111, a second lens unit 112, a reflector base 400, and a right reflector 410.

[0073] The first lens unit 111 may include a rectangular first inclined surface IS1, a first surface PS1, a second side surface SS12, and a fourth side surface SS14, as well as a trapezoidal first side surface SS11 and a third side surface SS13. The first inclined surface IS1 may be the lower surface of the first lens unit 111, and the first surface PS1 may be the upper surface of the first lens unit 111. The first side surface SS11 of the first lens unit 111 may be the left side surface, the second side surface SS12 may be the upper side surface, the third side surface SS13 may be the right side surface, and the fourth side surface SS14 may be the lower side surface. The first inclined surface IS1, the first surface PS1, the first side surface SS11, the second side surface SS12, the third side surface SS13, and the fourth side surface SS14 of the first lens unit 111 may be flat surfaces.

[0074] The second lens unit 112 may include a rectangular second inclined surface IS2, a second surface PS2, a second side surface SS22, and a fourth side surface SS24, as well as trapezoidal first side surface SS21 and a third side surface SS23. The second inclined surface IS2 may be the upper surface of the second lens unit 112, and the second surface PS2 may be the lower surface of the second lens unit 112. The first side surface SS21 of the second lens unit 112 may be the left side surface, the second side surface SS22 may be the upper side surface, the third side surface SS23 may be the right side surface, and the fourth side surface SS24 may be the lower side surface. The second inclined surface IS2, the second surface PS2, the first side surface SS21, the second side surface SS22, the third side surface SS23, and the fourth side surface SS24 of the second lens unit 112 may be flat surfaces.

[0075] The first tilted surface IS1 of the first lens unit 111 can be configured to face the second tilted surface IS2 of the second lens unit 112. The tilt angle θ3 of the first tilted surface IS1 relative to the second side surface SS12 of the first lens unit 111 can be substantially equal to the tilt angle θ4 of the second tilted surface IS2 relative to the fourth side surface SS24 of the second lens unit 112. The first tilted surface IS1 of the first lens unit 111 can be configured to be parallel to the second tilted surface IS2 of the second lens unit 112.

[0076] The reflector substrate 400 may be disposed between the first inclined surface IS1 of the first lens unit 111 and the second inclined surface IS2 of the second lens unit 112. The reflector substrate 400 may be formed of glass or plastic and may be transparent or translucent. For example, the reflector substrate 400 may be formed of ultrathin glass having a thickness of about 0.1 mm or less, or may be formed of a flexible film (such as a polyimide film).

[0077] The right reflector 410 can be disposed on the first surface of the reflector base 400. The first surface of the reflector base 400 can be the surface facing the first tilted surface IS1 of the first lens unit 111. The second surface of the reflector base 400 opposite to the first surface can be the surface facing the second tilted surface IS2 of the second lens unit 112.

[0078] Each of the right reflectors 410 can be formed by depositing a highly reflective metal (such as silver (Ag)) on a first surface of the reflector substrate 400. Each of the right reflectors 410 can be formed to have a small thickness in the range of a few micrometers to tens of micrometers. The first right reflector 411, the second right reflector 412, and the third right reflector 413 can be arranged along a first direction (X-axis direction).

[0079] A first adhesive layer 510 is disposed between a first tilted surface IS1 of the first lens unit 111 and a first surface of the reflector substrate 400, and bonds the first surface of the reflector substrate 400 to the first tilted surface IS1 of the first lens unit 111. A second adhesive layer 520 is disposed between a second tilted surface IS2 of the second lens unit 112 and a second surface of the reflector substrate 400, and bonds the second surface of the reflector substrate 400 to the second tilted surface IS2 of the second lens unit 112. Each of the first adhesive layer 510 and the second adhesive layer 520 may be an optically clear resin (OCR) or an optically clear adhesive (OCA).

[0080] The refractive index of the first lens unit 111 can be substantially equal to the refractive index of the second lens unit 112. To minimize the effects of refraction and reflection on the light supplied to the right lens 110 by the first adhesive layer 510 and the second adhesive layer 520 from the first display device 210, the refractive index of each of the first adhesive layer 510 and the second adhesive layer 520 can be designed to match the refractive index of the first lens unit 111 and the second lens unit 112. The differences between the refractive index of the first adhesive layer 510 and the refractive index of the first lens unit 111, the refractive index of the first adhesive layer 510 and the refractive index of the second lens unit 112, the refractive index of the second adhesive layer 520 and the refractive index of the second lens unit 112, and the refractive index of the second adhesive layer 520 and the refractive index of the second lens unit 112 can be about 0.1 or less.

[0102] A protective layer 1238 for insulating the thin-film transistor 1235 can be formed on the source electrode 1233, the drain electrode 1234, and the data lines. The protective layer 1238 can be an inorganic layer (e.g., silicon oxide (SiO2)). x ) layer, silicon nitride (SiN) x(layers or multiple layers composed of these layers).

[0103] A planarization layer 1239 may be formed on the protective layer 1238 to planarize the steps caused by the thin-film transistor 1235. The planarization layer 1239 may be made of an organic layer (such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin).

[0104] The light-emitting element layer 1240 is formed on the thin-film transistor layer 1230. The light-emitting element layer 1240 includes a light-emitting element and a pixel defining layer 1244.

[0105] The light-emitting element and pixel defining layer 1244 can be formed on the planarization layer 1239. The light-emitting element can be an organic light-emitting device. Each of the light-emitting elements may include an anode 1241, a light-emitting layer 1242, and a cathode 1243.

[0106] The anode 1241 can be formed on the planarization layer 1239. The anode 1241 can be connected to the drain electrode 1234 of the thin film transistor 1235 through contact holes that penetrate the protective layer 1238 and the planarization layer 1239.

[0107] A pixel defining layer 1244 may be formed on the planarization layer 1239 to cover the edge of the anode 1241 to define a pixel PX. For example, the pixel defining layer 1244 may be used as a pixel defining layer for defining a pixel PX. Each of the pixels PX is a region in which the anode 1241, the light-emitting layer 1242, and the cathode 1243 are sequentially stacked such that holes from the anode 1241 and electrons from the cathode 1243 combine in the light-emitting layer 1242 to emit light.

[0108] A light-emitting layer 1242 is formed on the anode 1241 and the pixel defining layer 1244. The light-emitting layer 1242 may be an organic light-emitting layer. Each of the light-emitting layers 1242 may emit one of red, green, and blue light. The red light may have a peak wavelength in the range of about 620 nm to about 750 nm, and the green light may have a peak wavelength in the range of about 495 nm to about 570 nm. The blue light may have a peak wavelength in the range of about 450 nm to about 495 nm. In an embodiment, each of the light-emitting layers 1242 may be a white light-emitting layer that emits white light. Each of the light-emitting layers 1242 may be a stack of red, green, and blue light-emitting layers, and may be a common layer shared by pixels PX. The first display device 210 may also include separate color filters for displaying red, green, and blue.

[0109] Each of the light-emitting layers 1242 may include a hole transport layer, a light-emitting layer, and an electron transport layer.

[0111] When the light-emitting element layer 1240 is formed as a top-emitting type emitting light in the upward direction, the anode 1241 can be made of a metallic material with high reflectivity (such as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and indium tin oxide (ITO / Al / ITO), an APC alloy, or a stacked structure of APC alloy and indium tin oxide (ITO / APC / ITO)). The APC alloy is an alloy of silver (Ag), palladium (Pd), and copper (Cu). The cathode 1243 can be made of a transparent conductive material (TCO) capable of transmitting light (such as indium tin oxide (ITO) or indium zinc oxide (IZO)) or a semi-transmissive conductive material (such as magnesium (Mg), silver (Ag), or an alloy of Mg and Ag). When the cathode 1243 is made of a semi-transmissive conductive material, the light output efficiency can be improved by the microcavity.

[0112] When the light-emitting element layer 1240 is formed as a bottom-emitting type that emits light in the downward direction, the anode 1241 can be made of a transparent conductive material (TCO) (such as indium tin oxide (ITO) or indium zinc oxide (IZO)) or a semi-transparent conductive material (such as magnesium (Mg), silver (Ag), or an alloy of Mg and Ag). The cathode 1243 can be made of a metallic material with high reflectivity (such as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and indium tin oxide (ITO / Al / ITO), an APC alloy, or a stacked structure of APC alloy and indium tin oxide (ITO / APC / ITO)). When the anode 1241 is made of a semi-transparent conductive material, the light output efficiency can be improved by using a microcavity.

[0113] A thin-film encapsulation layer 1300 may be formed on the light-emitting element layer 1240. The thin-film encapsulation layer 1300 serves to prevent oxygen or moisture from penetrating into the light-emitting layer 1242 and the cathode 1243. For this purpose, the thin-film encapsulation layer 1300 may include at least one inorganic layer. The inorganic layer may be made of silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, or titanium oxide. The thin-film encapsulation layer 1300 may also include at least one organic layer. The organic layer may be formed to a sufficient thickness to prevent particles from penetrating the thin-film encapsulation layer 1300 and entering the light-emitting layer 1242 and the cathode 1243. The organic layer may include any one of epoxy resin, acrylate, and polyurethane acrylate. An encapsulation substrate, instead of the thin-film encapsulation layer 1300, may also be disposed on the light-emitting element layer 1240.

[0114] The display area of ​​the second display device 220 can be the same as the one mentioned above. Figure 6 The display area DA of the first display device 210 is basically the same, so the description of the display area of ​​the second display device 220 is omitted.

[0115] Figures 7 to 9 It is used to explain the basis Figure 2 The embodiment of the optical device 1 provides a view of the augmented reality method.

[0116] Figure 7 It is a perspective view showing the right lens 110, the first display device 210, the right condensers 311 to 313 and the right reflector 410. Figure 8 This is a plan view seen from the first surface of the right lens 110. Figure 9 This is a right-side view seen from the right-side surface of the right lens 110.

[0117] Reference Figures 7 to 9 The display area DA of the first display panel 211 may include multiple areas for displaying multiple images. For example, the first display panel 211 may include a first area A1 for displaying a first image IM1, a second area A2 for displaying a second image IM2, and a third area A3 for displaying a third image IM3.

[0118] The first region A1, the second region A2, and the third region A3 of the first display panel 211 can be arranged along a first direction (X-axis direction). The first region A1 and the second region A2 of the first display panel 211 can be in contact with each other, and the second region A2 and the third region A3 can be in contact with each other. In an embodiment, a space where no image is displayed can be provided between the first region A1 and the second region A2 of the first display panel 211, and a space where no image is displayed can be provided between the second region A2 and the third region A3.

[0119] The first right condenser 311, the second right condenser 312, and the third right condenser 313 can be arranged along the first direction (X-axis direction). The first right reflector 411, the second right reflector 412, and the third right reflector 413 can be arranged along the first direction (X-axis direction).

[0120] The first region A1, the first right condenser 311, and the first right reflector 411 of the first display panel 211 can be stacked on top of each other in the third direction (Z-axis direction). The second region A2, the second right condenser 312, and the second right reflector 412 of the first display panel 211 can be stacked on top of each other in the third direction (Z-axis direction). The third region A3, the third right condenser 313, and the third right reflector 413 of the first display panel 211 can be stacked on top of each other in the third direction (Z-axis direction).

[0121] Images IM1 to IM3 displayed in areas A1 to A3 of the first display panel 211 can be focused onto right reflectors 411 to 413 by right condensers 311 to 313, respectively. Therefore, images IM1 to IM3 displayed in areas A1 to A3 of the first display panel 211 can be reflected to the user's right eye RE by right reflectors 411 to 413, respectively.

[0122] The first image IM1 displayed in the first region A1 of the first display panel 211 can be focused onto the first right reflector 411 by the first right convex lens 311a and the second right convex lens 311b of the first right condenser 311. The first right reflector 411 can reflect the first image IM1 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the first image IM1 can be formed on the retina of the user's right eye RE.

[0123] The second image IM2 displayed in the second region A2 of the first display panel 211 can be focused onto the second right reflector 412 by the first right convex lens 312a and the second right convex lens 312b of the second right condenser 312. The second right reflector 412 can reflect the second image IM2 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the second image IM2 can be formed on the retina of the user's right eye RE.

[0124] The third image IM3 displayed in the third region A3 of the first display panel 211 can be focused onto the third right reflector 413 by the first right convex lens 313a and the second right convex lens 313b of the third right condenser 313. The third right reflector 413 can reflect the third image IM3 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the third image IM3 can be formed on the retina of the user's right eye RE.

[0125] like Figures 7 to 9 As shown, the first image IM1, the second image IM2, and the third image IM3 displayed in the first region A1, the second region A2, and the third region A3 of the first display panel 211 can be formed on the retina of the user's right eye RE through the first right reflector 411, the second right reflector 412, and the third right reflector 413, respectively. Therefore, the user can see an image composed of the first image IM1, the second image IM2, and the third image IM3 through the right eye RE. Since the user can see the image composed of the first image IM1, the second image IM2, and the third image IM3 and the real image without moving the focus on the real image, augmented reality can be provided to the user.

[0126] When the first display panel 211 includes regions A1 to A3, the right condensers 311 to 313 can focus the images IM1 to IM3 of regions A1 to A3 of the first display panel 211 onto the right reflectors 411 to 413, respectively. When the first display panel 211 does not include regions A1 to A3, the right condensers must focus the image of the first display panel 211 onto all the right reflectors 411 to 413. Therefore, the refractive power of each of the right condensers 311 to 313 when the first display panel 211 includes regions A1 to A3 can be smaller than the refractive power of the right condenser when the first display panel 211 does not include regions A1 to A3. Therefore, the thickness of each of the right condensers 311 to 313 when the first display panel 211 includes regions A1 to A3 can be smaller than the thickness of the right condenser when the first display panel 211 does not include regions A1 to A3. Therefore, the size of the optical device 1 can be reduced.

[0127] When the first display panel 211 does not include regions A1 to A3, images that do not reach the right reflectors 411 to 413 among the multiple images of the first display panel 211 will be lost. For example, among the multiple images of the first display panel 211, images that reach the space between the first right reflector 411 and the second right reflector 412, and images that reach the space between the second right reflector 412 and the third right reflector 413, will be lost. However, when the first display panel 211 includes regions A1 to A3, since the images IM1 to IM3 of regions A1 to A3 of the first display panel 211 are focused on the right reflectors 411 to 413 respectively, the number of images that do not reach the right reflectors 411 to 413 can be reduced. Therefore, the brightness loss of the image provided by the optical device 1 can be reduced.

[0128] The augmented reality delivery method using the left lens 120, the second display device 220, the left condenser 320, and the left reflector 420 is the same as described above. Figures 7 to 9 The methods used to provide augmented reality are basically the same, so their descriptions are omitted.

The second right reflector 412 and the fifth right reflector 415 can be arranged along the second direction (Y-axis direction). The third right reflector 413 and the sixth right reflector 416 can be arranged along the second direction (Y-axis direction).

[0142] Images IM1 to IM6 displayed in areas A1 to A6 of the first display panel 211 can be focused onto right reflectors 411 to 416 by right condensers 311 to 316, respectively. Therefore, images IM1 to IM6 displayed in areas A1 to A6 of the first display panel 211 can be reflected to the user's right eye RE by right reflectors 411 to 416, respectively.

[0143] The first image IM1 displayed in the first region A1 of the first display device 210 can be focused onto the first right reflector 411 by the first right convex lens 311a and the second right convex lens 311b of the first right condenser 311. The first right reflector 411 can reflect the first image IM1 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the first image IM1 can be formed on the retina of the user's right eye RE.

[0144] The second image IM2 displayed in the second region A2 of the first display device 210 can be focused onto the second right reflector 412 by the first right convex lens 312a and the second right convex lens 312b of the second right condenser 312. The second right reflector 412 can reflect the second image IM2 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110.

Therefore, the fourth image IM4 can be formed on the retina of the user's right eye RE.

[0147] The fifth image IM5 displayed in the fifth region A5 of the first display device 210 can be focused onto the fifth right reflector 415 by the first right convex lens 315a and the second right convex lens 315b of the fifth right condenser 315. The fifth right reflector 415 can reflect the fifth image IM5 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the fifth image IM5 can be formed on the retina of the user's right eye RE.

The sixth right reflector 416 can reflect the sixth image IM6 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the sixth image IM6 can be formed on the retina of the user's right eye RE.

Therefore, the user can see an image IM composed of the first image IM1, second image IM2, third image IM3, fourth image IM4, fifth image IM5, and sixth image IM6 through the right eye RE. Since the user can see the image composed of the first image IM1, second image IM2, third image IM3, fourth image IM4, fifth image IM5, and sixth image IM6 and the real image without moving the focus on the real image, augmented reality can be provided to the user.

[0161] Figures 14 to 16 It is used to explain the basis Figure 13 The embodiment of the optical device 1 provides a view of the augmented reality method.

[0162] Figure 14 It is a perspective view showing the right lens 110, the first right display device 2110, the second right display device 2120, the third right display device 2130, the right condensers 311 to 313 and the right reflector 410. Figure 15 This is a plan view seen from the first surface of the right lens 110. Figure 16 This is a right-side view seen from the right-side surface of the right lens 110.

[0163] Figures 14 to 16 Implementation examples and Figures 7 to 9 The difference in the embodiment is that the first display device 210 includes a first right display panel 2111 for displaying a first image IM1, a second right display panel 2121 for displaying a second image IM2, and a third right display panel 2131 for displaying a third image IM3, in place of the first area A1 for displaying the first image IM1, the second area A2 for displaying the second image IM2, and the third area A3 for displaying the third image IM3.

[0164] Reference Figures 14 to 16 The first right display panel 2111, the second right display panel 2121, and the third right display panel 2131 can be arranged along a first direction (X-axis direction). The first right condenser 311, the second right condenser 312, and the third right condenser 313 can be arranged along the first direction (X-axis direction). The first right reflector 411, the second right reflector 412, and the third right reflector 413 can be arranged along the first direction (X-axis direction).

[0165] The first right display panel 2111, the first right condenser 311, and the first right reflector 411 can be stacked on top of each other in the third direction (Z-axis direction). The second right display panel 2121, the second right condenser 312, and the second right reflector 412 can be stacked on top of each other in the third direction (Z-axis direction). The third right display panel 2131, the third right condenser 313, and the third right reflector 413 can be stacked on top of each other in the third direction (Z-axis direction).

[0166] Images IM1 to IM3 displayed on the right display panels 2111, 2121, and 2131 can be focused onto the right reflectors 411 to 413 by the right condensers 311 to 313, respectively. Therefore, images IM1 to IM3 displayed on the right display panels 2111, 2121, and 2131 can be reflected to the user's right eye RE by the right reflectors 411 to 413, respectively.

[0167] The first image IM1 displayed on the first right display panel 2111 can be focused onto the first right reflector 411 by the first right convex lens 311a and the second right convex lens 311b of the first right condenser 311. The first right reflector 411 can reflect the first image IM1 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the first image IM1 can be formed on the retina of the user's right eye RE.

[0168] The second image IM2 displayed on the second right display panel 2121 can be focused onto the second right reflector 412 by the first right convex lens 312a and the second right convex lens 312b of the second right condenser 312. The second right reflector 412 can reflect the second image IM2 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the second image IM2 can be formed on the retina of the user's right eye RE.

[0169] The third image IM3 displayed on the third right display panel 2131 can be focused onto the third right reflector 413 by the first right convex lens 313a and the second right convex lens 313b of the third right condenser 313. The third right reflector 413 can reflect the third image IM3 incident from the first side surface of the right lens 110 onto the first surface of the right lens 110. Therefore, the third image IM3 can be formed on the retina of the user's right eye RE.

[0170] like Figures 14 to 16As shown, the first image IM1, the second image IM2, and the third image IM3 displayed on the first right display panel 2111, the second right display panel 2121, and the third right display panel 2131 can be formed on the retina of the user's right eye RE through the first right reflector 411, the second right reflector 412, and the third right reflector 413, respectively. Therefore, the user can see an image composed of the first image IM1, the second image IM2, and the third image IM3 through the right eye RE. Since the user can see the image composed of the first image IM1, the second image IM2, and the third image IM3 and the real image without moving the focus on the real image, augmented reality can be provided to the user.

[0171] When the first display device 210 includes right display panels 2111, 2121, and 2131, the right condensers 311 to 313 can focus the images IM1 to IM3 of the right display panels 2111, 2121, and 2131 onto the right reflectors 411 to 413, respectively. When the first display device 210 does not include right display panels 2111, 2121, and 2131, the right condensers must focus the images of the first display device 210 onto all the right reflectors 411 to 413. Therefore, the refractive power of each of the right condensers 311 to 313 when the first display device 210 includes right display panels 2111, 2121, and 2131 can be smaller than the refractive power of the right condensers when the first display device 210 does not include right display panels 2111, 2121, and 2131. Therefore, when the first display device 210 includes the right display panels 2111, 2121, and 2131, the thickness of each of the right condensers 311 to 313 can be smaller than the thickness of the right condenser when the first display device 210 does not include the right display panels 2111, 2121, and 2131. Thus, the size of the optical device 1 can be reduced.

[0172] When the first display device 210 does not include the right display panels 2111, 2121, and 2131, images that do not reach the right reflectors 411 to 413 among the multiple images of the first display device 210 will be lost. For example, images that travel between the first right reflector 411 and the second right reflector 412, and between the second right reflector 412 and the third right reflector 413, among the multiple images of the first display device 210, will be lost. However, when the first display device 210 includes the right display panels 2111, 2121, and 2131, since the images IM1 to IM3 of the right display panels 2111, 2121, and 2131 are focused on the right reflectors 411 to 413 respectively, the number of images that do not travel to the right reflectors 411 to 413 can be reduced. Therefore, the brightness loss of the image provided by the optical device 1 can be reduced.

[0173] The augmented reality delivery method using the left lens 120, the second display device 220, the left condenser 320, and the left reflector 420 is the same as described above. Figures 14 to 16 The methods used to provide augmented reality are basically the same, so their descriptions are omitted.

Therefore, images IM1 to IM6 displayed in areas A1' to A6' of the right display panels 2111, 2121, and 2131 can be reflected to the user's right eye RE by right reflectors 411 to 416, respectively.

[0196] In the optical device according to embodiments of the inventive concept, when the display panel comprises multiple regions or when it comprises multiple display panels, the condenser can focus images of the multiple regions or multiple display panels onto the reflector respectively. Since the refractive power of each condenser can be low, each condenser can be thin. Therefore, the size of the optical device can be reduced.

Therefore, the loss of image brightness can be reduced.

[0198] Although the inventive concept has been specifically shown and described with reference to embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made therein without departing from the spirit and scope of the inventive concept set forth in the claims.
