Description

Glass window of a display and an electronic device including the same

[0001] Embodiments of the present disclosure relate to a glass window of a variable display and an electronic device including the same.

[0002] Electronic devices can refer to devices that perform specified functions based on embedded programs, such as home appliances, electronic notebooks, portable multimedia players, mobile communication terminals, tablet PCs, audio / video devices, desktop / laptop computers, or in-vehicle navigation systems. Electronic devices are becoming increasingly slimmer, more rigid, and more aesthetically pleasing, while their functional elements are being differentiated.

[0003] Displays embedded in electronic devices are a core technology of the information and communication age, evolving toward thinner, lighter, more portable, and higher-performance displays. Recently, electronic devices incorporating flexible displays (e.g., stretchable displays, expandable displays) that can change the screen size (e.g., expand or contract) have been developed.

[0004] The above-described material is provided solely as background information to aid in understanding the embodiments of the present disclosure. No determination has been made, and no claims are made, as to whether any of the above material constitutes prior art in connection with the present disclosure.

[0005] An electronic device including a stretchable display (e.g., a flexible display, an expandable display) may have a screen whose physical size may change in a first direction (e.g., a portrait direction), in a second direction orthogonal to the first direction (e.g., a landscape direction), or in both the first direction and the second direction. As the physical size of the stretchable display panel changes, the physical size of the glass window may also change.

[0006] A glass window formed from a single material with a positive Poisson's ratio can be applied to a variable display panel. Conventional glass windows are prone to tensile failure and breakage due to their relatively high stiffness. Polymer windows can be applied to variable display panels, but their low stiffness can make them vulnerable to frontal impacts. Both glass and polymer windows can experience pixel distortion due to their positive Poisson's ratio.

[0007] Various embodiments of the present disclosure can provide a glass window of a variable display whose physical size can be changed according to a change in the physical size of the display panel, and an electronic device including the same.

[0008] Various embodiments of the present disclosure can provide a glass window of a variable display having a zero or negative Poisson's ratio and an electronic device including the same.

[0009] The technical challenges addressed in this document are not limited to the technical challenges mentioned above, and may be expanded upon without departing from the spirit and scope of the present disclosure. Additional technical challenges not mentioned herein will be readily apparent to those skilled in the art, as described below.

[0010] An electronic device according to one embodiment of the present disclosure may include a display panel and a protective structure (e.g., a glass window of a display) disposed on an upper portion of the display panel. The protective structure may include a plurality of glass patterns at least partially interconnected, a plurality of slit portions formed between the plurality of glass patterns, and an adhesive member disposed in a space formed by the plurality of slit portions. The protective structure may have a Poisson ratio of '0' or less.

[0011] An electronic device according to one embodiment of the present disclosure may include a display panel, a first protective structure (e.g., a glass window of the display) disposed on an upper portion of the display panel, and a second protective structure (e.g., a glass window of the display) disposed on a lower portion of the display panel. Each of the first and second protective structures may include a plurality of glass patterns at least partially interconnected, a plurality of slit portions formed between the plurality of glass patterns, and an adhesive member disposed in a space formed by the plurality of slit portions. The protective structure may have a Poisson ratio of '0' or less.

[0012] A glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns are connected.

[0013] According to one embodiment of the present disclosure, a glass window (e.g., a protective structure, a variable glass window) of a display has a deviation between the refractive index of glass patterns and the refractive index of an optical adhesive (e.g., an optical adhesive layer) of 0.01 or less, thereby preventing or reducing visibility of the boundary between the glass patterns and the optical adhesive (e.g., an optical adhesive layer).

[0014] According to one embodiment of the present disclosure, a glass window (e.g., a protective structure, a variable glass window) of a display can have a relatively wide slit portion of a hinge portion where glass patterns are connected. By forming the slit portion of the hinge portion to have a relatively wide width, pressure (e.g., stress) applied to the hinge portion can be dispersed.

[0015] In order to disperse pressure (e.g., stress) applied to a hinge portion, a glass window (e.g., a protective structure, a deformable glass window) of a display according to one embodiment of the present disclosure may include a plurality of groove patterns as glass patterns. The length (e.g., area) of the glass patterns in contact with the hinge portion increases due to the plurality of groove patterns, thereby dispersing the pressure (e.g., stress) applied to the hinge portion.

[0016] According to one embodiment of the present disclosure, a glass window (e.g., a protective structure, a deformable glass window) of a display may have a plurality of first glass patterns arranged in a first layer and a plurality of second glass patterns arranged in a second layer, such that the ratio of the arrangement of the glass patterns to the total area of ​​the glass window (e.g., the protective structure, the deformable glass window) is 100% or more. Through this, the maximum tensile stress of the glass window (e.g., the protective structure, the deformable glass window) may be reduced, while the strength of the hinge part in a front impact situation may be secured.

[0017] An electronic device according to one embodiment of the present disclosure can absorb impact applied from the lower portion of the display panel (e.g., a deformable display panel) and protect the lower portion of the display panel (e.g., a deformable display panel) by disposing a panel support layer including a glass window (e.g., a protective structure, a deformable glass window) under the display panel (e.g., a deformable display panel).

[0018] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

[0087] FIG. 2 is a block diagram of a display module according to one embodiment of the present disclosure.

[0088] Referring to FIG. 2, a display module (160) (e.g., the display module (160) of FIG. 1) of an electronic device (e.g., the electronic device (101) of FIG. 1) according to one embodiment of the present disclosure may include a display (200), a display driver IC (230, display driver IC) (e.g., a display driver) for driving the display (200), a touch circuit (250) for detecting a touch on the display (200), and a sensor module (176) (e.g., the sensor module (176) of FIG. 1). Hereinafter, the display driver IC (230) may be referred to as 'DDIC'.

[0089] According to one embodiment, the DDIC (230) may operate based on the control of a processor (e.g., the processor (120) of FIG. 1). For example, the DDIC (230) may include an interface module (231), a memory (233) (e.g., a buffer memory), an image processing module (235), or a mapping module (237).

[0090] According to one embodiment, the DDIC (230) can receive image information including image data or an image control signal corresponding to a command for controlling the image data from another component of an electronic device (e.g., the electronic device (101) of FIG. 1) through an interface module (231).

[0091] According to one embodiment, the image information may be received from a processor (120) (e.g., the main processor (121) of FIG. 1) (e.g., an application processor) or an auxiliary processor (e.g., the auxiliary processor (123) of FIG. 1) (e.g., a graphics processing unit) that operates independently of the functions of the main processor (121).

[0092] According to one embodiment, the DDIC (230) may communicate with the touch circuit (250) and / or the sensor module (176) (e.g., the sensor circuit) using the interface module (231). In addition, the DDIC (230) may store at least some of the received image information in the memory (233). As an example, the DDIC (230) may store at least some of the received image information in the memory (233) on a frame-by-frame basis.

[0093] According to one embodiment, the image processing module (235) may perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least a portion of the image data based at least on characteristics of the image data or characteristics of the display (200).

[0094] According to one embodiment, the mapping module (237) may generate a voltage value or a current value corresponding to the image data pre-processed or post-processed through the image processing module (235). According to one embodiment, the generation of the voltage value or the current value may be performed based at least in part on, for example, properties of the pixels of the display (200) (e.g., arrangement of pixels (RGB stripe or pentile structure), or size of each sub-pixel).

[0095] According to one embodiment, at least some pixels of the display (200) may be driven based at least in part on, for example, the voltage value or current value, so that visual information (e.g., text, an image, or an icon) corresponding to the image data may be displayed through the display (200).

[0096] According to one embodiment, the touch circuit (250) may include a touch sensor (251) (e.g., a touch screen) and a touch sensor IC (253, touch sensor integrated circuit).

[0097] According to one embodiment, the touch circuit (250) can detect a touch input or hovering input for a specific location of the display (200). The touch sensor IC (253) can control the touch sensor (251) (e.g., a touch screen) to detect the touch input or hovering input. For example, the touch sensor IC (253) can detect the touch input or hovering input by measuring a change in a signal (e.g., voltage, light quantity, resistance, or charge quantity) for a specific location of the display (200). The touch sensor IC (253) can provide information (e.g., location, area, pressure, or time) about the detected touch input or hovering input to the processor (120) (e.g., transmit to the processor (120), input to the processor (120).

[0098] According to one embodiment, the touch sensor (251) (e.g., a touch screen) may be applied in an add-on manner in which the touch sensor (251) is manufactured separately and separately placed on the upper part (e.g., top) of the display (200).

[0099] According to one embodiment, the touch sensor (251) (e.g., a touch screen) may be applied in an on cell manner in which the touch sensor (251) is placed on the upper portion of the display (200).

[0100] According to one embodiment, the touch sensor (251) (e.g., a touch screen) may be applied in an in-cell manner in which the touch sensor (251) is arranged together with the pixels of the display (200).

[0101] According to one embodiment, at least a portion of the touch circuit (250) (e.g., the touch sensor IC (253)) may be included as part of the DDIC (230) or the display (200).

[0102] According to one embodiment, at least a portion of the touch circuit (250) (e.g., touch sensor IC (253)) may be included as part of another component (e.g., auxiliary processor (123)) disposed external to the display module (160).

[0103] According to one embodiment, the display module (160) may further include at least one sensor of the sensor module (176) (e.g., a sensor circuit), or a control circuit of the sensor module (176) (e.g., a sensor circuit). For example, the at least one sensor or the control circuit thereof may be embedded in a portion of the display module (160) (e.g., the display (200) or the DDIC (230)) or in a portion of the touch circuit (250).

[0104] For example, if a sensor module (176) (e.g., a sensor circuit) embedded in a display module (160) includes a pressure sensor, the pressure sensor can obtain (e.g., receive) pressure information associated with a touch input through a portion or the entire area of ​​the display (200).

[0105] According to one embodiment, a touch sensor (251) or sensor module (176) (e.g., sensor circuit) may be positioned between pixels of a pixel layer of the display (200), or above or below the pixel layer.

[0106] According to one embodiment, the display module (160) may include a digitizer (not shown) for detecting an input (e.g., a touch input or a hovering input) of an electronic pen (e.g., a stylus pen) and a digitizer driver (not shown) for driving the digitizer. For example, the digitizer and the digitizer driver may be included as components of the display module (160). For example, the digitizer driver for driving the digitizer may be included as a separate component from the display module (160). For example, the digitizer may convert analog coordinates (e.g., a position) of the electronic pen (e.g., a stylus pen) into digital coordinate data. The digitizer may transmit the digital coordinate data to a processor (e.g., the processor (120) of FIG. 1) and / or a DDIC (230).

[0107] FIG. 3A is a diagram illustrating a variable display of an electronic device according to various embodiments of the present disclosure.

[0108] FIG. 3b is a drawing showing that the area (e.g., screen size) of the variable display illustrated in FIG. 3a is changed.

[0109] Referring to FIGS. 3A and 3B, an electronic device (e.g., electronic device (101) of FIG. 1) according to various embodiments of the present disclosure may include a display (301) (e.g., display (200) of FIG. 2).

[0110] According to one embodiment, the display (301) may include a flexible display (e.g., a stretchable display, an expandable display) in which the physical size of the screen can be expanded in a first direction (e.g., the y-axis direction) and reduced in a direction opposite to the first direction (e.g., the -y-axis direction).

[0111] According to one embodiment, the display (301) may include a flexible display (e.g., a stretchable display, an expandable display) in which the physical size of the screen can be expanded in a second direction (e.g., an x-axis direction) and reduced in a direction opposite to the second direction (e.g., a -x-axis direction).

[0112] According to one embodiment, the display (301) may include a flexible display (e.g., a stretchable display, an expandable display) in which the physical size of the screen can be expanded in the first direction (e.g., the y-axis direction) and the second direction (e.g., the x-axis direction), and reduced in the opposite direction of the first direction (e.g., the y-axis direction) (e.g., the -y-axis direction) and the opposite direction of the second direction (e.g., the x-axis direction) (e.g., the -x-axis direction).

[0113] In FIG. 3A, a collapsed state (310) of a display (301) and an expanded state (320) in which the display (301) is expanded in a first direction (e.g., y-axis direction) are illustrated as examples. The display (301) has a stretchable property and may include a plurality of pixels (Ps). When the display (301) is expanded, the spacing between the plurality of pixels (Ps) may increase. When the display (301) is collapsed, the spacing between the plurality of pixels (Ps) may decrease.

[0114] According to one embodiment, when the display (301) expands (e.g., stretches) in a first direction (e.g., in the y-axis direction), a spacing between a plurality of pixels (Ps) in the first direction (e.g., in the y-axis direction) may increase. For example, when the display (301) expands (e.g., stretches) in a first direction (e.g., in the y-axis direction), a spacing between a first pixel (p1) and a second pixel (p2) may expand (e.g., stretch) from a first spacing (d1) to a second spacing (d2). Additionally, a spacing between a third pixel (p3) and a fourth pixel (p4) may expand (e.g., stretch) from a first spacing (d1) to a second spacing (d2). In this way, the spacing between the first pixel (p1) and the second pixel (p2) and the spacing between the third pixel (p3) and the fourth pixel (p4) in the second direction (e.g., in the x-axis direction) can be expanded (e.g., stretched), so that the screen size in the second direction (e.g., in the x-axis direction) can be expanded.

[0115] According to one embodiment, when the display (301) expands (e.g., stretches) in a second direction (e.g., in the x-axis direction), a spacing between a plurality of pixels (Ps) in the second direction (e.g., in the x-axis direction) may increase. For example, when the display (301) expands (e.g., stretches) in a second direction (e.g., in the x-axis direction), a spacing between a first pixel (p1) and a third pixel (p3) may expand (e.g., stretch) from a third spacing (d3) to a fourth spacing (d4). Additionally, a spacing between a second pixel (p2) and a fourth pixel (p4) may expand (e.g., stretch) from a third spacing (d3) to a fourth spacing (d4). In this way, the spacing between the first pixel (p1) and the third pixel (p3) and the spacing between the second pixel (p2) and the fourth pixel (p4) in the second direction (e.g., in the x-axis direction) can be expanded (e.g., stretched), so that the screen size in the second direction (e.g., in the x-axis direction) can be expanded.

[0116] According to one embodiment, when the display (301) is expanded (e.g., stretched) in a first direction (e.g., y-axis direction) and a second direction (e.g., x-axis direction), the spacing between the plurality of pixels (Ps) in the first direction (e.g., y-axis direction) and the second direction (e.g., x-axis direction) may increase.

[0117] According to one embodiment, a plurality of pixels (Ps) of a display (301) may emit light to display an object (312) (e.g., an image, text). When the display (301) is expanded in a first direction (e.g., a y-axis direction), the spacing between the plurality of pixels (Ps) in the first direction (e.g., a y-axis direction) increases, and an expansion area (314) may be created as much as the spacing between the plurality of pixels (Ps) in the first direction (e.g., a y-axis direction) increases. Here, the display (301) may not be expanded in a second direction (e.g., an x-axis direction) and may have a fixed size. The present invention is not limited thereto, and the size of the display (301) may also be expanded in the second direction (e.g., an x-axis direction).

[0118] According to one embodiment, when the display (301) expands or contracts in a first direction (e.g., in the y-axis direction), the processor (e.g., the processor (120) of FIG. 1) can control the DDI (e.g., the DDI (230) of FIG. 2) to change (e.g., expand or contract) the size of an object (312) (e.g., an image, text) in the first direction (e.g., in the y-axis direction) according to the ratio at which the display (301) expands or contracts in the first direction (e.g., in the y-axis direction).

[0119] According to one embodiment, when the display (301) expands or contracts in a second direction (e.g., in the x-axis direction), the processor (e.g., the processor (120) of FIG. 1) can control the DDI (e.g., the DDI (230) of FIG. 2) to change (e.g., expand or contract) the size of an object (312) (e.g., an image, text) in the second direction (e.g., in the x-axis direction) to match the ratio at which the display (301) expands or contracts in the second direction (e.g., in the x-axis direction).

[0120] According to one embodiment, when the display (301) is expanded or reduced in a first direction (e.g., y-axis direction) and a second direction (e.g., x-axis direction), a processor (e.g., processor (120) of FIG. 1) can control a DDI (e.g., DDI (230) of FIG. 2) to change (e.g., expand or reduce) the size of an object (312) (e.g., an image, text) in the first direction (e.g., y-axis direction) and the second direction (e.g., x-axis direction) according to the ratio of the expansion or reduction of the display (301) in the first direction (e.g., y-axis direction) and the second direction (e.g., x-axis direction).

[0121] FIG. 4 is a drawing showing a laminated structure of a display including a variable glass window and a variable display panel according to one embodiment of the present disclosure.

[0122] Referring to FIG. 4, the display (400) may include a display panel (410) (e.g., a variable display panel), an optical film layer (420), a panel support layer (430), and a glass window (500) (e.g., a protective structure, a variable glass window, a variable protective layer).

[0123] In one embodiment, an optical film layer (420) may be disposed on top of a display panel (410) (e.g., a variable display panel). A panel support layer (430) may be disposed on the bottom of the display panel (410) (e.g., a variable display panel).

[0124] For example, a glass window (500) (e.g., a protective structure, a variable glass window, a variable protective layer) may be placed on top of an optical film layer (420).

[0125] For example, a glass window (500) (e.g., protective structure, deformable glass window, deformable protective layer) may be placed to protect the display panel (410) (e.g., variable display panel) from impact applied from the front (e.g., the surface on which the screen is displayed) and to prevent scratches caused by a user's touch on the screen.

[0126] A glass window (600) (e.g., a protective structure, a variable glass window) according to one embodiment of the present disclosure may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (610) are connected.

[0127] For example, in order to support the display panel (410) (e.g., a variable display panel) from below, the panel support layer (430) may be formed as a plate made of a metal material.

[0128] FIG. 5 is a drawing showing that glass patterns of a glass window (e.g., a protective structure, a variable glass window) of a display illustrated in FIG. 4 are arranged in a tessellation form.

[0129] Referring to FIG. 5, since the variable display can be placed not only on an electronic device but also on a wearable electronic device or a human body, a glass window (500) (e.g., a protective structure, a variable glass window) whose size can be flexibly physically changed must be applied to the variable display.

[0130] A glass window (500) (e.g., a protective structure, a variable glass window) according to one embodiment of the present disclosure can protect a display panel (e.g., a variable display panel) while securing impact strength by implementing a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (510) are connected. FIG. 5 illustrates, as an example, one glass pattern being connected to two adjacent glass patterns. For example, when each of the plurality of glass patterns (510) has a triangular shape, a corner portion of a glass pattern can be connected to a corner portion of an adjacent glass pattern.

[0131] According to one embodiment, three or more parts of a glass window (e.g., a protective structure, a deformable glass window) may be interconnected. For example, FIG. 5 illustrates an example in which three parts of a glass window (500) (e.g., a protective structure, a deformable glass window) are interconnected. According to one embodiment, a plurality of glass patterns (510) of a glass window (500) (e.g., a protective structure, a deformable glass window) may be arranged in a tessellation form. For example, a slit portion (520) may be arranged between the plurality of glass patterns (510).

[0132] For example, the slit portion (520) may be filled with an optical adhesive (e.g., an optical adhesive layer). The optical adhesive (e.g., an optical adhesive layer) may include an optically clear resin (OCR) or an optically clear adhesive (OCA).

[0133] For example, by arranging glass patterns (510) in a tessellation form, pixel distortion due to Poisson's ratio can be suppressed. For example, FIG. 5 illustrates an example in which glass patterns (510) have a triangular shape. However, the present invention is not limited thereto, and glass patterns (510) may have a circular or polygonal shape.

[0134] The glass window (500) (e.g., protective structure, variable glass window) may have a Poisson's ratio of 0 or negative depending on the tessellation shape of the glass patterns (510) and the slit (520). For example, the glass window (500) (e.g., protective structure, variable glass window) may be physically enlarged and reduced in the x-axis and y-axis directions.

[0135] [Mathematical Formula 1]

[0136]

[0137] For example, if the Poisson's ratio is greater than 0, shrinkage in width may occur during tension. If the Poisson's ratio is '0', there is no change in width during tension. If the Poisson's ratio is less than '0', the width may increase during tension.

[0138] For example, Poisson's ratio can be calculated by Equation 1. In Equation 1, dε axial is the strain in the axial direction (e.g. x-direction), dε trans may mean strain in a direction perpendicular to the axis (e.g., y-axis direction). If the strain in the axial direction (e.g., x-axis direction) is positive, the Poisson's ratio is calculated as a positive number because the direction perpendicular to the axis has a negative strain. However, the glass window (500) of the present invention (e.g., protective structure, variable glass window) has positive strain in both the axial direction (e.g., x-axis direction) and the direction perpendicular to the axis (e.g., y-axis direction), so the Poisson's ratio may be negative.

[0139] FIG. 6 is a diagram showing a glass window (e.g., a protective structure, a deformable glass window) of a display before expansion (e.g., before stretching) and after expansion (e.g., after stretching) according to one embodiment of the present disclosure.

[0140] FIG. 7 is a drawing showing an enlarged view of glass patterns of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0141] Referring to FIGS. 6 and 7, a glass window (600) (e.g., a protective structure, a variable glass window) according to one embodiment of the present disclosure may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (610) are connected.

[0142] According to one embodiment, a plurality of glass patterns (610) of a glass window (600) (e.g., a protective structure, a deformable glass window) may be interconnected such that at least a portion of adjacent glass patterns (610) are interconnected. For example, slit portions (620) may be arranged between the plurality of glass patterns (610). For example, the slit portions (620) may be filled with an optical adhesive portion (630) (e.g., an optical adhesive layer). The optical adhesive portion (630) (e.g., an optical adhesive layer) may include an optically clear resin (OCR) or an optically clear adhesive (OCA).

[0143] According to one embodiment, the glass window (600) (e.g., protective structure, variable glass window) may also expand or contract as the display panel (e.g., variable display panel) expands or contracts.

[0144] For example, when the glass window (600) (e.g., protective structure, variable glass window) is reduced, the spacing between the slits (620) may become narrower (621).

[0145] For example, when the glass window (600) (e.g., protective structure, variable glass window) is expanded, the spacing between the slits (620) can be widened (622).

[0146] For example, adjacent glass patterns (610) may be interconnected and adjacent slit portions (620) may be spaced apart at equal intervals.

[0147] For example, when the glass window (600) (e.g., protective structure, variable glass window) is in an expanded state, the hinge portion (623) to which the glass patterns (610) are connected may be formed with a relatively narrow spacing between the slit portions (620), and the central portion (624) of the slit portions (620) may be formed with a relatively wide spacing.

[0148] For example, in a glass window (600) according to an embodiment of the present invention (e.g., a protective structure, a variable glass window), the deviation between the refractive index of the glass patterns (610) and the refractive index of the optical adhesive portion (630) (e.g., an optical adhesive layer) may be 0.01 or less. If the difference between the refractive index of the glass patterns (610) and the refractive index of the optical adhesive portion (630) (e.g., an optical adhesive layer) is large, the boundary may be visible, but in a glass window (600) according to an embodiment of the present invention (e.g., a protective structure, a variable glass window), the deviation between the refractive index of the glass patterns (610) and the refractive index of the optical adhesive portion (630) (e.g., an optical adhesive layer) is 0.01 or less, so that the boundary may be prevented or reduced from being visible.

[0149] Figures 8 to 10 are drawings showing the pressure (e.g., stress) applied to the hinge portion according to the shape of the glass patterns.

[0150] Referring to FIG. 8, a glass window (800) (e.g., a protective structure, a variable glass window) according to one embodiment of the present invention may include glass patterns (810) and slit portions (820).

[0151] For example, slit portions (820) may be arranged between a plurality of glass patterns (810). For example, the slit portions (820) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0152] According to one embodiment, when the width (821) of the slit portion (820) of the hinge portion (840) to which the glass patterns (810) are connected is formed narrow, pressure (e.g., stress) may be concentrated on the hinge portion (840). For example, looking at the pressure applied to the hinge portion (840), the pressure (e.g., stress) applied may be smaller as it is closer to the slit portion (820). The pressure (e.g., stress) applied to the first region (841) closest to the slit portion (820) may be the smallest, the pressure applied to the second region (842) may be greater than that applied to the first region (841), and the pressure (e.g., stress) applied to the third region (843) may be greater than that applied to the second region (842).

[0153] In order to prevent breakage of the glass window (800) (e.g., protective structure, variable glass window), the pressure (e.g., stress) applied to the hinge portion (840) can be distributed.

[0154] Referring to FIG. 9, a glass window (900) (e.g., a protective structure, a variable glass window) according to one embodiment of the present invention may include glass patterns (910) and slit portions (920).

[0155] For example, slit portions (920) may be arranged between a plurality of glass patterns (910). For example, the slit portions (920) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0156] According to one embodiment, the width (921) of the slit portion (920) of the hinge portion (940) to which the glass patterns (910) are connected can be formed relatively wide (e.g., wider than the width (821) of the slit portion (820) of the hinge portion (840) of FIG. 8). By forming the width (921) of the slit portion (920) of the hinge portion (940) relatively wide, the pressure (e.g., stress) applied to the hinge portion (940) can be dispersed.

[0157] Referring to FIG. 10, a glass window (1000) (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present invention may include glass patterns (1010) and slit portions (1020).

[0158] For example, a glass window (1000) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (1010) are connected.

[0159] For example, slit portions (1020) may be arranged between a plurality of glass patterns (1010). For example, the slit portions (1020) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0160] According to one embodiment, the width (1021) of the slit portion (1020) of the hinge portion (1040) to which the glass patterns (1010) are connected can be formed relatively wide (e.g., wider than the width (821) of the slit portion (820) of the hinge portion (840) of FIG. 8). By forming the width (1021) of the slit portion (1020) of the hinge portion (1040) relatively wide, the pressure (e.g., stress) applied to the hinge portion (1040) can be dispersed.

[0161] According to one embodiment, to distribute pressure (e.g., stress) applied to the hinge portion (1040), the glass patterns (1010) may include a plurality of groove patterns (1012).

[0162] For example, a plurality of groove patterns (1012) may be formed in a portion adjacent to the hinge portion (1040). The length (e.g., area) of the glass patterns (1010) in contact with the hinge portion (1040) increases due to the plurality of groove patterns (1012), thereby dispersing the pressure (e.g., stress) applied to the hinge portion (1040).

[0163] [Table 1]

[0164]

[0165] Referring to Table 1, for example, 'A' represents the maximum pressure (e.g., stress) applied to the glass window (800) of FIG. 8 and the pressure applied to the hinge portion (840). A slit portion (820) having a sharp portion adjacent to the hinge portion (840) of the glass window (800) of FIG. 8 and having a wider width (821) (e.g., a width that is cut open) as it moves away from the hinge portion (840) can be applied. By applying such a slip portion (820) and glass pattern (810), the pressure (e.g., stress) can be concentrated at the hinge portion (840).

[0166] For example, 'B' represents the maximum pressure (e.g., stress) applied to the glass window (900) of FIG. 9 and the pressure applied to the hinge portion (840). A slit portion (920) having a wide width (921) (e.g., a cut-open width) adjacent to the hinge portion (940) of the glass window (900) of FIG. 9 can be applied. By applying such a slip portion (920) and glass pattern (910), the pressure (e.g., stress) can be distributed at the hinge portion (940).

[0167] For example, 'C' represents the maximum pressure (e.g., stress) applied to the glass window (1000) of Fig. 10 and the pressure applied to the hinge portion (840). The width (1021) (e.g., the width cut open) of the portion adjacent to the hinge portion (1040) of the glass window (1000) of Fig. 10 may have a wide shape, and a slip portion (1020) in which a groove pattern (1012) is formed may be applied. By applying the glass pattern (1010) and the groove pattern (1012), the pressure (e.g., stress) may be distributed at the hinge portion (940).

[0168] FIG. 11 is a drawing showing a groove pattern formed in glass patterns of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0169] Referring to FIG. 11, a glass window (1100) of a display according to one embodiment of the present invention (e.g., a variable glass window, glass window (600) of FIGS. 6 and 7) may include glass patterns (1110) (e.g., glass patterns (610) of FIGS. 6 and 7) and slit portions (1120) (e.g., slit portions (620) of FIGS. 6 and 7).

[0170] For example, a glass window (1100) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (1110) are connected.

[0171] For example, slit portions (1120) may be arranged between a plurality of glass patterns (1110). For example, the slit portions (1120) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0172] According to one embodiment, to distribute pressure (e.g., stress) applied to the glass window (1100), the glass patterns (1110) may include a plurality of groove patterns (1112).

[0173] For example, a plurality of groove patterns (1112) may be arranged in a single row on one side of the glass patterns (1110). For example, since a portion without glass patterns (1110) becomes a slit portion (1120), the slit portion (1120) may include inverse groove patterns having a shape opposite to that of the plurality of groove patterns (1112).

[0174] For example, a plurality of groove patterns (1112) may be arranged adjacent to a hinge portion (e.g., hinge portion (1040) of FIG. 10) to which glass patterns (1110) are connected. The length (e.g., area) of the glass patterns (1110) in contact with the hinge portion (1040) increases due to the plurality of groove patterns (1112), thereby dispersing the pressure (e.g., stress) applied to the hinge portion (1040).

[0175] FIG. 12 is a drawing showing a groove pattern formed in glass patterns of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0176] Referring to FIG. 12, a glass window (1200) of a display according to one embodiment of the present invention (e.g., a variable glass window, glass window (600) of FIGS. 6 and 7) may include glass patterns (1210) (e.g., glass patterns (610) of FIGS. 6 and 7) and slit portions (1220) (e.g., slit portions (620) of FIGS. 6 and 7).

[0177] For example, a glass window (1200) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (1210) are connected.

[0178] For example, slit portions (1220) may be arranged between a plurality of glass patterns (1210). For example, the slit portions (1220) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0179] According to one embodiment, to distribute pressure (e.g., stress) applied to the glass window (1200), the glass patterns (1210) may include a plurality of groove patterns (1212, 1214).

[0180] For example, the plurality of groove patterns (1212, 1214) may include a first groove pattern (1212) arranged in a single row on a first side of the glass patterns (1210) and a second groove pattern (1214) arranged in a single row on a second side of the glass patterns (1210).

[0181] For example, the first groove pattern (1212) and the second groove pattern (1214) can be arranged to face each other.

[0182] For example, the protruding portion (e.g., protruding portion) of the first groove pattern (1212) and the protruding portion (e.g., protruding portion) of the second groove pattern (1214) may be arranged to correspond (e.g., aligned). The recessed portion (e.g., sunken portion) of the first groove pattern (1212) and the recessed portion (e.g., sunken portion) of the second groove pattern (1214) may be arranged to correspond (e.g., aligned).

[0183] For example, since the portion without glass patterns (1210) becomes the slit portion (1220), the slit portion (1220) can include inverse groove patterns of opposite shapes to the first groove pattern (1212) and the second groove pattern (1214).

[0184] For example, a plurality of groove patterns (1212, 1214) may be arranged adjacent to a hinge portion (e.g., hinge portion (1040) of FIG. 10) to which glass patterns (1210) are connected. The length (e.g., area) of the glass patterns (1210) in contact with the hinge portion (1040) increases due to the plurality of groove patterns (1212, 1214), thereby dispersing the pressure (e.g., stress) applied to the hinge portion (1040).

[0185] FIG. 13 is a drawing showing a groove pattern formed in glass patterns of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0186] Referring to FIG. 13, a glass window (1300) according to one embodiment of the present invention (e.g., a variable glass window, the glass window (600) of FIGS. 6 and 7) may include glass patterns (1310) (e.g., the glass patterns (610) of FIGS. 6 and 7) and slit portions (1320) (e.g., the slit portions (620) of FIGS. 6 and 7).

[0187] For example, a glass window (1300) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (1310) are connected.

[0188] For example, slit portions (1320) may be arranged between a plurality of glass patterns (1310). For example, the slit portions (1320) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0189] According to one embodiment, to distribute pressure (e.g., stress) applied to the glass window (1300), the glass patterns (1310) may include a plurality of groove patterns (1312, 1314).

[0190] For example, the plurality of groove patterns (1312, 1314) may include a first groove pattern (1312) arranged in a single row on a first side of the glass patterns (1310) and a second groove pattern (1314) arranged in a single row on a second side of the glass patterns (1310).

[0191] For example, the first groove pattern (1312) and the second groove pattern (1314) can be arranged to face each other.

[0192] For example, the protruding portion (e.g., protruding portion) of the first groove pattern (1312) and the protruding portion (e.g., protruding portion) of the second groove pattern (1314) may be arranged to be staggered from each other, and the protruding portion (e.g., protruding portion) of the first groove pattern (1312) and the sunken portion (e.g., recessed portion) of the second groove pattern (1314) may be arranged to be corresponding (e.g., arranged to be aligned).

[0193] For example, for example, the sunken portion (e.g., recessed portion) of the first groove pattern (1312) and the sunken portion (e.g., recessed portion) of the second groove pattern (1314) may be arranged to be staggered from each other, and the sunken portion (e.g., recessed portion) of the first groove pattern (1312) and the protruding portion (e.g., protruding portion) of the second groove pattern (1314) may be arranged to correspond (e.g., be arranged to be aligned).

[0194] For example, since the portion without glass patterns (1310) becomes the slit portion (1320), the slit portion (1320) may include inverse groove patterns of opposite shapes to the first groove pattern (1312) and the second groove pattern (1314).

[0195] For example, a plurality of groove patterns (1312, 1314) may be arranged adjacent to a hinge portion (e.g., hinge portion (1040) of FIG. 10) to which glass patterns (1310) are connected. The length (e.g., area) of the glass patterns (1310) in contact with the hinge portion (1040) increases due to the plurality of groove patterns (1312, 1314), thereby dispersing the pressure (e.g., stress) applied to the hinge portion (1040).

[0196] FIG. 14 is a drawing showing a groove pattern formed in glass patterns of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0197] Referring to FIG. 14, a glass window (1400) according to one embodiment of the present invention (e.g., a variable glass window, glass window (600) of FIGS. 6 and 7) may include glass patterns (1410) (e.g., glass patterns (610) of FIGS. 6 and 7) and slit portions (1420) (e.g., slit portions (620) of FIGS. 6 and 7).

[0198] For example, a glass window (1400) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (1410) are connected.

[0199] For example, slit portions (1420) may be arranged between a plurality of glass patterns (1410). For example, the slit portions (1420) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0200] According to one embodiment, to distribute pressure (e.g., stress) applied to the glass window (1400), the glass patterns (1410) may include a plurality of groove patterns (1412).

[0201] For example, multiple groove patterns (1412) can be arranged between slit portions (1420).

[0202] For example, the plurality of groove patterns (1412) may have a form in which wedge-shaped patterns are repeatedly arranged. The wedge-shaped patterns constituting the plurality of groove patterns (1412) may be arranged in one row or multiple rows.

[0203] For example, a plurality of groove patterns (1412) may be arranged adjacent to a hinge portion (e.g., hinge portion (1040) of FIG. 10) to which glass patterns (1410) are connected. The length (e.g., area) of the glass patterns (1410) in contact with the hinge portion (1040) increases due to the plurality of groove patterns (1412), thereby dispersing pressure (e.g., stress) applied to the hinge portion (1040).

[0204] According to one embodiment, the effect of distributing the pressure (e.g., stress) applied to the hinge portion (1040) may vary depending on the width (e.g., area) and spacing of the groove patterns (1012, 1112, 1212, 1214, 1312, 1314, 1412) illustrated in FIGS. 10 to 14.

[0205] For example, the width of the groove patterns (1012, 1112, 1212, 1214, 1312, 1314, 1412) may be 30um or more.

[0206] For example, the spacing between groove patterns (1012, 1112, 1212, 1214, 1312, 1314, 1412) may be 50um or more.

[0207] In one embodiment, the area of ​​the glass patterns (610, 810, 910, 1010, 1110, 1210, 1310, 1410) may be 80% or more of the total area of ​​the glass window (600, 800, 900, 1000, 1100, 1200, 1300, 1400).

[0208] According to one embodiment, the glass patterns (610, 810, 910, 1010, 1110, 1210, 1310, 1410) can have an elastic elongation of 5% or greater.

[0209] According to one embodiment, the glass patterns (610, 810, 910, 1010, 1110, 1210, 1310, 1410) may be formed of one material selected from the group consisting of soda lime, aluminosilicate, lithium aluminosilicate, borosilicate, boroaluminosilicate, and lithium silicate, or may be formed of a composite material of at least two of the materials.

[0210] According to one embodiment, the optically clear resin (OCR) or optically clear adhesive (OCA) filled in the slit portion (620, 820, 920, 1020, 1120, 1220, 1320, 1420) may be formed of one of silicone, acrylic, urethane, urethane acrylic, or at least two of them.

[0211] Figure 15 is a drawing (1500) showing the impact strength according to the width (e.g., area) of the hinge portion where glass patterns are connected.

[0212] Referring to FIG. 15, the impact strength of the glass window may vary depending on the width (e.g., area) of the hinge portion (e.g., hinge portion (1040) of FIG. 10).

[0213] For example, when the width (e.g., width) of the hinge portion (e.g., hinge portion (1040) of FIG. 10) is about 100 um, the glass window may be broken when the electronic device is dropped from a height of about 25 cm.

[0214] For example, when the width (e.g., width) of the hinge portion (e.g., hinge portion (1040) of FIG. 10) is about 150 um, the glass window may be broken when the electronic device is dropped from a height of about 29 cm.

[0215] For example, when the width (e.g., width) of the hinge portion (e.g., hinge portion (1040) of FIG. 10) is about 200 um, the glass window may be broken when the electronic device is dropped from a height of about 32 cm.

[0216] For example, when the width (e.g., width) of the hinge portion (e.g., hinge portion (1040) of FIG. 10) is about 250 um, the glass window may be broken when the electronic device is dropped from a height of about 37 cm.

[0217] For example, when the width (e.g., width) of the hinge portion (e.g., hinge portion (1040) of FIG. 10) is about 300 um, the glass window may be broken when the electronic device is dropped from a height of about 39 cm.

[0218] As a result of performing an impact test while sequentially increasing the width (e.g., width) of the hinge portion (e.g., hinge portion (1040) of FIG. 10) from 100 um to 300 um, it can be confirmed that the impact strength of the glass window increases as the width (e.g., width) of the hinge portion (e.g., hinge portion (1040) of FIG. 10) increases.

[0219] FIG. 16 is a drawing showing glass patterns and slit portions of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0220] Referring to FIG. 16, a glass window (1600) (e.g., a protective structure, a variable glass window) according to one embodiment of the present invention may include glass patterns (1610) and slit portions (1620).

[0221] For example, a glass window (1600) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (1610) are connected.

[0222] For example, slit portions (1620) may be arranged between a plurality of glass patterns (1610). For example, the slit portions (1620) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0223] For example, slit portions (1620) may be arranged in a form that surrounds multiple glass patterns (1610).

[0224] For example, a hinge portion (1621) with open slit portions (1620) can be formed so that adjacent glass patterns (1610) can be connected to each other.

[0225] For example, the area of ​​the glass patterns (1610) may be 80% or more of the total area of ​​the glass window (1600) (e.g., protective structure, deformable glass window), and the area of ​​the slit portions (1620) may be 20% or less. Through this, the maximum tensile stress of the glass window (1600) (e.g., protective structure, deformable glass window) may be reduced, while the strength of the hinge portion in a frontal impact situation may be secured.

[0226] For example, a glass window (1600) (e.g., a protective structure, a variable glass window) may have slit portions (1620) arranged in a form that surrounds a plurality of glass patterns (1610), thereby reducing the stiffness applied to the hinge portion, and may expand or reduce the size of the glass window (1600) (e.g., a protective structure, a variable glass window) even with a small force.

[0227] FIG. 17 is a drawing showing a protrusion formed in a slit portion of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0228] Referring to FIG. 17, a glass window (1700) (e.g., a protective structure, a variable glass window) according to one embodiment of the present invention may include glass patterns (1710) and slit portions (1720).

[0229] For example, a glass window (1700) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (1710) are connected.

[0230] For example, slit portions (1720) may be arranged between a plurality of glass patterns (1710). For example, the slit portions (1720) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0231] For example, slit portions (1720) may be arranged in a form that surrounds multiple glass patterns (1710).

[0232] For example, an open hinge portion (1721) may be formed in the slit portions (1720) so that adjacent glass patterns (1710) can be connected to each other.

[0233] For example, a protrusion (1712) may be formed in the slit portion (1720). A portion of the slit portion (1720) positioned on the side of the glass pattern (1710) may protrude in the direction of the glass pattern (1710) to form the protrusion (1712).

[0234] For example, the area of ​​the glass patterns (1710) may be 80% or more of the total area of ​​the glass window (1700) (e.g., protective structure, deformable glass window), and the area of ​​the slit portions (1720) may be 20% or less. Through this, the maximum tensile stress of the glass window (1700) (e.g., protective structure, deformable glass window) may be reduced, while the strength of the hinge portion in a frontal impact situation may be secured.

[0235] For example, a glass window (1700) (e.g., a protective structure, a variable glass window) may have slit portions (1720) arranged in a form that surrounds a plurality of glass patterns (1710), thereby reducing the stiffness applied to the hinge portion, and may expand or reduce the size of the glass window (1700) (e.g., a protective structure, a variable glass window) even with a small force.

[0236] For example, if an impact is applied to a portion where there are no glass patterns (1710) with a sharp object (e.g., a pen), the glass window (1700) (e.g., a protective structure, a deformable glass window) may be broken. However, by reducing the area of ​​the slit portions (1720) and increasing the area of ​​the plurality of glass patterns (1710), the glass window (1700) (e.g., a protective structure, a deformable glass window) from being broken due to the impact can be prevented or reduced. By forming a protrusion (1712) in the slit portion (1720) and covering a portion other than the tensile region with the plurality of glass patterns (1710), the glass window (1700) (e.g., a protective structure, a deformable glass window) from being broken due to the impact can be prevented or reduced.

[0237] FIG. 18 is a drawing showing the width (w1) of a glass pattern and the width (Ws) of an adhesive portion in a state before expansion of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0238] FIG. 19 is a drawing showing the width (w2) of a glass pattern and the width (Ws) of an adhesive portion in a state after expansion of a glass window (e.g., a protective structure, a variable glass window) of a display according to one embodiment of the present disclosure.

[0239] Referring to FIGS. 18 and 19, a glass window (1800) (e.g., a protective structure, a variable glass window) according to one embodiment of the present invention may include glass patterns (1810) and slit portions (1820).

[0240] For example, a glass window (1800) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (1810) are connected.

[0241] For example, slit portions (1820) may be arranged between a plurality of glass patterns (1810). For example, the slit portions (1820) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0242] For example, slit portions (1820) may be arranged in a form that surrounds multiple glass patterns (1810).

[0243] For example, a hinge portion (1821) with open slit portions (1820) can be formed so that adjacent glass patterns (1810) can be connected to each other.

[0244] For example, the area of ​​the glass patterns (1810) may be 80% or more of the total area of ​​the glass window (1800) (e.g., protective structure, deformable glass window), and the area of ​​the slit portions (1820) may be 20% or less. Through this, the maximum tensile stress of the glass window (1800) (e.g., protective structure, deformable glass window) may be reduced, while the strength of the hinge portion in a frontal impact situation may be secured.

[0245] For example, a glass window (1800) (e.g., a protective structure, a variable glass window) may have slit portions (1820) arranged in a form that surrounds a plurality of glass patterns (1810), thereby reducing the stiffness applied to a hinge portion, and may expand or reduce the size of the glass window (1800) (e.g., a protective structure, a variable glass window) even with a small force.

[0246] For example, the elongation of the optical adhesive (630) (e.g., OCR, OCA) filled in the slit portion (1820) of the glass window (1800) (e.g., protective structure, variable glass window) may be 200% to 800%.

[0247] [Mathematical Formula 2]

[0248]

[0249] In a case where the glass patterns (1810) are arranged in a substantially square tessellation shape (or a substantially rhombus tessellation shape), the elongation of the slit portion (1820) can be calculated using Equation 2. In Equation 2, W1 may denote the width of one unit of the glass patterns (1810) in a state before expansion. W2 may denote the width of one unit of the glass patterns (1810) in a state after expansion. Ws may denote the width of the slit portion (1820). In Equation 2, target may denote the target elongation of the glass window (1800) (e.g., a protective structure, a variable glass window). λ_OCR may denote the elongation of the optical adhesive portion (630) (e.g., OCR, OCA). An approximate value of the elongation of the optical adhesive portion (630) (e.g., OCR, OCA) is " =" can be expressed as ". In this case, 'k' is " "It can mean the ratio of the slit width defined as". Since the maximum elastic elongation may vary depending on the material of the optical adhesive (630) (e.g., OCR, OCA), " "The maximum value of ( ) may vary depending on the “k”. If two values ​​of “λ_OCR_max, λ” are known, “k” can be derived and reflected in setting the elongation of the glass window (1800) (e.g., protective structure, variable glass window).

[0250] Using mathematical expression 2, the target glass window (1800) (e.g., protective structure, variable glass window) can be calculated, and the width of the slit portion (1820) can be set to be smaller than the elongation of the optical adhesive portion (630) (e.g., OCR, OCA) based on the elongation of the glass window (1800) (e.g., protective structure, variable glass window).

[0251] [Table 2]

[0252]

[0253] Referring to Table 2 above, for example, when a glass window (1800) is applied to a foldable electronic device, an elongation of the glass window (1800) (e.g., a protective structure, a variable glass window) of 105% conductivity can be targeted.

[0254] For example, in the case of a wearable electronic device in the form of clothing, it is necessary to attach the display to the user's body. Therefore, when a glass window (1800) is applied to a wearable electronic device in the form of clothing, an elongation of the glass window (1800) (e.g., a protective structure, a variable glass window) of approximately 120% can be targeted.

[0255] For example, in the case of a skin-attached wearable electronic device, the display needs to be attached in close contact with the skin for a long time. Therefore, when a glass window (1800) is applied to a skin-attached wearable electronic device, an elongation of the glass window (1800) (e.g., a protective structure, a variable glass window) of approximately 150% can be targeted. At this time, the elongation of the optical adhesive portion (630) (e.g., OCR, OCA) according to the ratio of the width of the glass patterns (1810) of one unit to the width of the slit portion (1820) must be maintained below a certain level. To this end, the slit portion width ratio (k) can be 0.1 or more.

[0260] According to one embodiment, to distribute pressure (e.g., stress) applied to the hinge portion (2030) to which the glass patterns (2010) are connected, the glass patterns (2010) may include a plurality of groove patterns (2012).

[0261] For example, a plurality of groove patterns (2012) may be formed in a portion adjacent to the hinge portion (2030). The length (e.g., area) of the glass patterns (2010) in contact with the hinge portion (2030) increases due to the plurality of groove patterns (2012), thereby dispersing the pressure (e.g., stress) applied to the hinge portion (2030).

[0339] Referring to FIG. 28, a glass window (2800) according to one embodiment of the present invention (e.g., a variable glass window, the glass window (600) of FIGS. 6 and 7) may include glass patterns (2810) (e.g., the glass patterns (610) of FIGS. 6 and 7) and slit portions (2820) (e.g., the slit portions (620) of FIGS. 6 and 7).

[0340] For example, a glass window (2800) (e.g., a protective structure, a variable glass window) may have a Poisson's ratio of 0 or negative through a structure in which a plurality of glass patterns (2810) are connected.

[0341] For example, slit portions (2820) may be arranged between a plurality of glass patterns (2810). For example, the slit portions (2820) may be filled with an optical adhesive (e.g., an optical adhesive portion (630) of FIG. 6).

[0342] According to one embodiment, to distribute pressure (e.g., stress) applied to the glass window (2800), the glass patterns (2810) may include a plurality of groove patterns (2811, 2812).

[0343] For example, multiple groove patterns (2811, 2812) can be formed with different lengths and thicknesses.

[0344] For example, the first groove pattern (2811) may be formed with a first length, and the second groove pattern (2812) may be formed with a second length that is longer than the first length.

[0345] For example, the first groove pattern (2811) may be formed with a first width, and the second groove pattern (2812) may be formed with a second width that is wider than the first width.

[0346] For example, the first groove pattern (2811) may be formed in a bar shape with a constant length and width. The second groove pattern (2812) may be formed in a form that integrates a slope having a constant curvature and a bar shape with a constant length.

[0347] A glass window (2800) according to one embodiment of the present disclosure can distribute pressure (e.g., stress) at a hinge portion by adjusting at least one of the length, width, and spacing of a plurality of groove patterns (2811, 2812).

[0348] FIG. 29 is a diagram showing a laminated structure of a display including a variable glass window and a variable display panel according to one embodiment of the present disclosure, and showing that the glass window is arranged in place of a panel support layer arranged at the bottom of the display panel.

[0349] Referring to FIG. 29, the display (2900) may include a display panel (410) (e.g., a variable display panel), an optical film layer (420), a panel support layer (2910), and a glass window (500) (e.g., a protective structure, a variable glass window, a variable protective layer).

[0350] In one embodiment, an optical film layer (420) may be disposed on top of a display panel (410) (e.g., a variable display panel). A panel support layer (2910) may be disposed on the bottom of the display panel (410) (e.g., a variable display panel).

[0351] For example, a glass window (500) (e.g., a protective structure, a variable glass window, a variable protective layer) may be placed on top of an optical film layer (420).

[0352] For example, a glass window (500) (e.g., protective structure, deformable glass window, deformable protective layer) may be placed to protect the display panel (410) (e.g., variable display panel) from impact applied from the front (e.g., the surface on which the screen is displayed) and to prevent scratches caused by a user's touch on the screen.

[0353] According to one embodiment, a panel support layer (2910) may be disposed to support the display panel (410) (e.g., a variable display panel) from below. For example, the panel support layer (2910) may include the same glass window as the glass window (500) (e.g., a protective structure, a variable glass window, a variable protective layer). The panel support layer (2910) may include a plurality of glass patterns (e.g., a plurality of glass patterns (610) of FIGS. 6 and 7) and a slit portion (e.g., a slit portion (620) of FIGS. 6 and 7). At least some of the adjacent glass patterns (610) of the panel support layer (2910) may be interconnected. For example, the slit portion (620) may be filled with an optical adhesive portion (e.g., an optical adhesive portion (630) of FIGS. 6 and 6). The optical adhesive (630) (e.g., optical adhesive layer) may include optically clear resin (OCR) or optically clear adhesive (OCA).

[0354] By placing a panel support layer (2910) including a glass window on the lower part of the display panel (410) (e.g., a variable display panel), the impact applied from the lower part of the display panel (410) (e.g., a variable display panel) can be absorbed and the lower part of the display panel (410) (e.g., a variable display panel) can be protected.

[0369] According to one embodiment, the plurality of glass patterns (610) may include a protruding structure arranged in a certain direction.

[0370] According to one embodiment, the area of ​​the plurality of glass patterns (610) may be 80% or more of the total area of ​​the protective structure (e.g., glass window (600)).

[0371] According to one embodiment, the plurality of glass patterns (610) may have an elastic elongation of 5% or more.

[0372] According to one embodiment, the difference in refractive index between the plurality of glass patterns (610) and the adhesive member (e.g., the optical adhesive member (630) of FIG. 7) may be within 0.01.

[0373] According to one embodiment, the plurality of glass patterns (610) may be composed of the same patterns or may be composed of two or more different patterns.

[0377] A glass window (e.g., a protective structure, a variable glass window) according to one embodiment of the present disclosure can prevent or reduce visibility of the boundary between the glass patterns and the optical adhesive (e.g., an optical adhesive layer) by having a deviation between the refractive index of the glass patterns and the refractive index of the optical adhesive (e.g., an optical adhesive layer) of 0.01 or less.

[0378] A glass window (e.g., a protective structure, a variable glass window) according to one embodiment of the present disclosure can have a slit portion of a hinge portion where glass patterns are connected formed with a relatively wide width.
