Detailed Implementation

[0027] The subject matter of this disclosure will be described more fully below with reference to the accompanying drawings, in which embodiments of the disclosure are illustrated. As those skilled in the art will recognize, the described embodiments may be modified in one or more suitable and different ways without departing from the spirit or scope of this disclosure. The drawings and description are to be considered illustrative rather than restrictive in nature. Throughout the drawings and written description, the same reference numerals denote the same elements, and their repeated description may not be provided in the specification.

[0028] When describing embodiments of this disclosure (e.g., when describing embodiments of this disclosure), the use of "may" refers to "one or more embodiments of this disclosure".

[0029] In the context of this application and unless otherwise defined, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively.

[0030] As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Singular expressions include plural expressions unless the context clearly specifies otherwise.

[0031] As used in this document, the terms “and / or” or “or” include any and all combinations of one or more of the related listed items.

[0032] Throughout this disclosure, expressions such as “at least one of,” “one of,” and “selected from” modify the entire list of elements if they follow / before a list element (e.g., when preceding a list element), and do not modify individual elements within the list. For example, “at least one of a, b, and c,” “selected from at least one of a, b, and c,” “selected from at least one of a to c,” etc., mean only a, only b, only c, both a and b (e.g., both a and b), both a and c (e.g., both a and c), both b and c (e.g., both b and c), all of a, b, and c, or variations thereof.

[0033] As used herein, the terms “substantially,” “about,” and similar terms are used as approximations rather than terms of degree, and are intended to account for inherent deviations in measured or calculated values ​​that would be recognized by a person skilled in the art. Given the measurements discussed and the errors associated with the measurement of a particular quantity (e.g., limitations of the measurement system), “about,” as used herein, includes the value and refers to a range of acceptable deviations from the particular value as determined by a person skilled in the art. For example, “about” could mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the value. Furthermore, it should be understood that even if the terms “about,” “approximation,” or “substantially” are not explicitly stated in a given element (e.g., a claim element), the scope of such elements is intended to include non-substantial variations or variations understood by a person skilled in the art. For example, the numerical values ​​and ranges provided herein are intended to include tolerances and measurement uncertainties that would be recognized by a person skilled in the art, and elements (e.g., claim elements) should be interpreted accordingly to include such equivalences.

[0034] Any numerical range described herein is intended to include all subranges containing the same numerical precision within the described range. For example, the range “1.0 to 10.0” is intended to include all subranges between (and inclusive of) the described minimum value of 1.0 and the described maximum value of 10.0, such as having a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6. Any maximum numerical limit described herein is intended to include all lower numerical limits contained therein, and any minimum numerical limit described in this disclosure is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to modify this disclosure, including the claims, to clearly describe any subranges contained within the range expressly described herein.

[0035] In this disclosure, it will be understood that if an element (e.g., a region, layer, portion, etc.) is referred to as being “on,” “connected to,” or “linked to” another element (e.g., when an element (e.g., a region, layer, portion, etc.) is referred to as being “on,” “connected to,” or “linked to” another element), then it may be directly on, directly connected to, or directly linked to the other element, or there may be an intermediary element therein. Conversely, if an element is referred to as being “directly” on, directly connected to, or directly linked to another element (e.g., when an element is referred to as being “directly” on, directly connected to, or directly linked to another element), then there is no intermediary element therein.

[0036] In the accompanying drawings, the thickness, ratio, and size of the components may be exaggerated in order to effectively or appropriately illustrate the technical content.

[0037] It will be understood that although the terms “first,” “second,” etc., may be used herein to describe one or more suitable elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this disclosure, a first element may be referred to as a second element. Similarly, a second element may also be referred to as a first element.

[0038] In this disclosure, for ease of description, terms such as “below,” “down,” “above,” “up,” etc., are used to describe the relationship between one element and another(s) as shown in the accompanying drawings. The foregoing terms are relative concepts and are described based on the directions indicated in the accompanying drawings.

[0039] It will be understood that the terms “includes,” “including,” “has,” and / or “having,” if used in this disclosure (e.g., as used in this disclosure), specify the presence of the stated features, integrals, steps, operations, elements, components, and / or groups thereof, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof. For example, it should be understood that the terms “comprise(s)” / “comprising,” “include(s)” / “including” or “have” / “has” / “having” specify the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof. Furthermore, the terms “comprise(s)”, “include(s)”, “have”, “has”, or similar terms include or support the terms “composed of” and “substantially composed of”, indicating the presence of the stated feature, whole, step, operation, element, and / or component, while other features, wholes, steps, operations, elements, components, and / or groups thereof are absent or substantially absent.

[0040] The terms "part" or "unit" refer to a software or hardware component that performs a specific (e.g., set or predetermined) function. For example, a hardware component may include a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). A software component may refer to executable code in addressable storage media and / or data used by the executable code. Thus, for example, a software component may be an object-oriented software component, a class component, and a task component, and may include processes, functions, attributes, procedures, subroutines, program code segments, drivers, firmware, microcode, data, databases, data structures, tables, arrays, and / or variables.

[0041] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have substantially the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms, such as those defined in commonly used dictionaries, shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field, and shall not be interpreted in an idealized or overly formalized sense unless expressly defined herein.

[0159] Optical layer 300 may be disposed on or provided on sensor layer 200. Optical layer 300 may include light blocking layer 310, multiple color filters 320 and planarization layer 330.

[0160] The light-blocking layer 310 may be disposed or provided to overlap with the conductive pattern of the second sensor conductive layer 240. The sensor protective layer 250 may be disposed or provided between the light-blocking layer 310 and the second sensor conductive layer 240. The light-blocking layer 310 may prevent external light from being reflected by the second sensor conductive layer 240 (or reduce the degree or occurrence of external light reflection). The material constituting the light-blocking layer 310 is not particularly limited, as long as the material is capable of absorbing light.

The black colorant may include black dyes and / or black pigments. The black colorant may include carbon black, metals such as chromium, and / or oxides thereof.

[0161] Multiple openings, OPR, OPG, and OPB, can be defined in the light-blocking layer 310. The openings OPR, OPG, and OPB can overlap with the first emitting layer ELR, the second emitting layer ELG, and the third emitting layer ELB, respectively, and can be referred to as the first opening OPR, the second opening OPG, and the third opening OPB.

The first color filter 320R, the second color filter 320G, and the third color filter 320B can be configured or provided to correspond to the first opening OPR, the second opening OPG, and the third opening OPB, respectively. The first color filter 320R, the second color filter 320G, and the third color filter 320B can transmit light from the first light-emitting layer ELR, the second light-emitting layer ELG, and the third light-emitting layer ELB that overlap with the first color filter 320R, the second color filter 320G, and the third color filter 320B.

[0162] The planarization layer 330 may cover the light-blocking layer 310 and the color filter 320. The planarization layer 330 may provide a flat (e.g., substantially flat) surface thereon. The planarization layer 330 may comprise an organic material. The planarization layer 330 may have a refractive index similar to that of the first film layer 410 described herein. For example, the difference between the refractive index of the planarization layer 330 and the refractive index of the first film layer 410 may be about 0.05 or less. For example, the planarization layer 330 may have a refractive index of about 1.54.

[0163] In one or more embodiments, optical layer 300 may include a reflection control layer instead of color filter 320. For example, in Figure 5In this configuration, the color filter 320 may not be provided, and a reflection control layer may be added where the color filter 320 is not provided. The reflection control layer may selectively absorb a portion of the frequency band of light reflected from inside the display layer 100 and / or the electronic device 1000 or incident from outside the display layer 100 and / or the electronic device 1000.

[0164] Window 400 may be disposed or provided on optical layer 300. Window 400 may protect display layer 100 from external influences. In one or more embodiments, window 400 may include a plurality of adhesive layers 401 and 402, a first film layer 410, a second film layer 420, and a protective layer 430 (or a first protective layer 430).

[0165] The first film layer 410 can be bonded to the upper surface of the planarization layer 330 using a first adhesive layer 401 between the first film layer 410 and the planarization layer 330. The refractive index of the first film layer 410 can be from about 1.5 to about 1.52. The first film layer 410 can include glass and can be ultrathin glass (UTG). For example, the thickness TK1 of the first film layer 410 can be about 1 mm or less. For example, the thickness TK1 of the first film layer 410 can be about 30 μm. Because the first film layer 410 is designed as a thin film glass layer with a thickness TK1, it is feasible to provide a window 400 with impact resistance, flexibility, and improved or enhanced light transmittance.

[0166] The second film layer 420 can be bonded to the first film layer 410 using a second adhesive layer 402 between the second film layer 420 and the first film layer 410. The thickness TK2 of the second film layer 420 can be set or predetermined to be from about 55 μm to about 75 μm, and can be, for example, about 65 μm. By designing the thickness TK2 of the second film layer 420 to be within a set or predetermined range, the light transmittance of the window 400 can be improved or enhanced, and the non-uniformity of light visible through the window 400 can be reduced, thereby improving or enhancing the external visibility of the image.

[0167] The refractive index of the second film layer 420 can be similar for each wavelength in the visible light range. For example, the minimum and maximum values ​​of the refractive index of the second film layer 420 measured in the visible light range can exist within a similar range with small deviations, and the similarity range can be about 0.2 or less. Therefore, the second film layer 420 can be designed such that (e.g.) the deviation of the refractive index for each wavelength in the visible light range is about 0.2 or less. For example, the difference between the minimum and maximum values ​​of the refractive index of the second film layer 420 measured in the wavelength range of about 450 nm to about 650 nm can be about 0.2 or less. The refractive index of the second film layer 420 can vary depending on the material, the composition ratio and molecular structure of the material, the thickness of the second film layer 420, etc. The second film layer 420 can be a polymer film composed of organic materials. The second film layer 420 can be a film composed of, for example, cellulose triacetate (TAC), acrylic acid, and / or polycarbonate (PC).

[0168] In one or more embodiments, provided that the second film layer 420 has the aforementioned refractive index range, the second film layer 420 may comprise a polyethylene terephthalate (PET) film having an undercoat whose refractive index is controlled or selected. For example, the second film layer 420 may comprise a polyethylene terephthalate film including an undercoat having a refractive index of about 1.47 to about 1.66. For example, if the second film layer 420 comprises a polyethylene terephthalate film (e.g., when the second film layer 420 comprises a polyethylene terephthalate film), the refractive index of the undercoat may be limited to about 1.47 to about 1.66. A more detailed description thereof will be given herein.

[0169] In one or more embodiments, the second film layer 420 may have a refractive index similar to that of an adjacent layer (e.g., the first film layer 410). The difference between the refractive index of the second film layer 420 and the refractive index of the first film layer 410 may be about 0.1 or less, and for example, about 0.05 or less. According to this disclosure, by designing the refractive index of the second film layer 420 to have a low deviation for each wavelength and fall within a range similar to the refractive index of the first film layer 410, the reflectivity of external light can be reduced, and for example, significant reflection of blue light can be reduced, thereby improving or enhancing the visibility of the electronic device 1000.

[0170] The protective layer 430 may be disposed or provided on the second film layer 420. The protective layer 430 may be the uppermost layer among the layers forming or providing the window 400, and may be a layer configured or arranged to provide the outer surface of the window 400. The protective layer 430 may have sufficient or suitable rigidity to protect the display surface of the electronic device 1000.

[0171] The protective layer 430 may include an organic material. In one or more embodiments, the protective layer 430 may be in contact with the second film layer 420. In this case, the protective layer 430 may be formed or provided by depositing and / or coating an organic material on the upper surface of the second film layer 420. Therefore, an adhesive layer may not be provided between the protective layer 430 and the second film layer 420. In one or more embodiments, this is only shown by way of example, and the protective layer 430 may be provided in the form of a film and bonded to the second film layer 420 by an adhesive layer, or it may be provided in the form of a coating on an adhesive layer and attached to the second film layer 420. The protective layer 430 according to one or more embodiments may be provided in one or more embodiments, and the embodiments of this disclosure are not limited thereto.

[0172] The thickness TK3 of the protective layer 430 can be less than the thickness TK2 of the second film layer 420. The thickness TK3 of the protective layer 430 can be set or predetermined to be about 5 μm or less. By designing the thickness TK3 of the protective layer 430 to be within a set or predetermined range, the light transmittance of the window 400 can be improved or enhanced, and the non-uniformity of light visible through the window 400 can be reduced, thereby improving or enhancing the external visibility of the image.

[0173] The protective layer 430 may have a refractive index similar to that of the first film layer 410. The difference between the refractive index of the protective layer 430 and the refractive index of the first film layer 410 may be about 0.1 or less, and for example, about 0.05 or less. According to this disclosure, by designing the refractive index of the protective layer 430 to be within a range similar to that of the first film layer 410, the reflectivity of external light can be reduced, and for example, significant reflection of blue light can be reduced, thereby improving or enhancing the visibility of the electronic device 1000.

[0174] The protective layer 430 may also include a low-reflection layer. The refractive index of the low-reflection layer may be about 1.48 or less. The thickness of the low-reflection layer may be about 10 nm to about 200 nm. In one or more embodiments, the protective layer 430 may also include an anti-fingerprint layer. For example, the protective layer 430 may have a structure in which two or more layers are stacked.

[0175] In one or more embodiments, each of the first adhesive layer 401 and the second adhesive layer 402 constituting the window 400 may be a pressure-sensitive adhesive layer. The thickness TK01 of the first adhesive layer 401 or the thickness TK02 of the second adhesive layer 402 may be less than the thickness of the second film layer 420. Each of the thickness TK01 of the first adhesive layer 401 and the thickness TK02 of the second adhesive layer 402 may be about 50 μm or less, for example, about 50 μm. If the thickness TK01 of the first adhesive layer 401 and the thickness TK02 of the second adhesive layer 402 become too large or considerably large (e.g., when the thickness TK01 of the first adhesive layer 401 and the thickness TK02 of the second adhesive layer 402 become too large or considerably large), the light transmittance may decrease and the bending characteristics may deteriorate. If the thickness TK01 of the first adhesive layer 401 and the thickness TK02 of the second adhesive layer 402 become too small or considerably small (e.g., when the thickness TK01 of the first adhesive layer 401 and the thickness TK02 of the second adhesive layer 402 become too small or considerably small), delamination between the layers may occur or impact resistance may decrease, thereby reducing reliability. According to this disclosure, it is feasible to design the thickness TK01 of the first adhesive layer 401 and the thickness TK02 of the second adhesive layer 402 to provide a window 400 with sufficient or suitable impact resistance and improved or enhanced visibility within a set or predetermined range.

[0176] The first adhesive layer 401 and the second adhesive layer 402 may have refractive indices similar to those of adjacent layers. For example, the first adhesive layer 401 and the second adhesive layer 402 may have refractive indices similar to those of the first film layer 410. The difference between the refractive index of each of the first adhesive layer 401 and the second adhesive layer 402 and the refractive index of the first film layer 410 may be about 0.1 or less, and for example, about 0.05 or less. According to this disclosure, by designing the refractive indices of the first adhesive layer 401 and the second adhesive layer 402 to have low deviations for each wavelength and to be similar to those of adjacent layers, the reflectivity of external light can be reduced, and for example, significant reflection of blue light can be reduced, thereby improving or enhancing the visibility of the electronic device 1000.

[0177] In one or more embodiments, the outermost film of window 400 may have sufficient or suitable hardness to protect underlying components, such as a display panel. For example, in one or more embodiments, the outermost film may be a second film layer 420, and the second film layer 420 may have a nanoindentation Vickers hardness of about 35 Hv or greater and a crack strain of about 2% or greater. By selecting a film with sufficient or suitable hardness as the outermost film, window 400 can stably or appropriately provide the function of protecting the display panel.

[0178] Figure 6It is a cross-sectional view showing a portion of an electronic device according to one or more embodiments. Figure 6 It shows the relationship with Figure 5 The corresponding area. (Similar to...) Figure 5 Compared to the electronic device 1000 shown, such as Figure 6 The electronic device 1000-1 shown may include windows 400-1 with different layer structures. Repeated descriptions are not required below.

[0179] refer to Figure 6 The window 400-1 may also include an additional protective layer 440 (hereinafter referred to as the second protective layer 440) separate from the first protective layer 430. The second protective layer 440 may be disposed or provided between the second adhesive layer 402 and the second film layer 420. The thickness TK4 of the second protective layer 440 may be set or predetermined in the range of about 5 μm to about 50 μm.

[0180] If the second membrane layer 420 is composed of a material with a high water vapor transmission rate (WVTR) (e.g., when the second membrane layer 420 is composed of a material with a high water vapor transmission rate (WVTR), then the second protective layer 440 can prevent defects in the second membrane layer 420 (or reduce the degree or occurrence of defects) and improve or enhance the reliability of the window 400-1. For example, if the second membrane layer 420 is provided as a TAC membrane (e.g., when the second membrane layer 420 is provided as a TAC membrane), then the second membrane layer 420 can have a high water vapor transmission rate of about 1000 or greater, which may reduce durability in high temperature and high humidity environments. According to this disclosure, by further including the second protective layer 440, defects due to moisture permeability can be prevented (or the degree or occurrence of defects due to moisture permeability can be reduced).

[0181] The second protective layer 440 may include an organic material. The second protective layer 440 may be provided in the form of a film. In this case, an additional adhesive layer may be further disposed or provided between the second protective layer 440 and the second film layer 420. The second protective layer 440 may include, for example, polyethylene terephthalate (PET), acrylic acid, cyclic olefin polymer (COP), polyimide (PI), polyethylene naphthalate (PEN), and / or polyamide (PA). However, these are described as examples, and the second protective layer 440 may be formed or provided directly by coating under the second film layer 420.

[0182] In one or more embodiments, the second protective layer 440 may comprise an elastic material, such as polyurethane (PU), polyester, and / or acrylic foam. In this case, the modulus of the second protective layer 440 may be about half or less of the modulus of the second film layer 420. The modulus of the second protective layer 440 may be about 1 GPa or less. Therefore, sufficient or suitable impact resistance can be ensured to protect the underlying layer.

[0183] In this disclosure, modulus may refer to the elastic modulus. For example, modulus may be defined as the ratio of stress to strain. For example, the modulus of the second protective layer 440 may correspond to the slope of the elastic segment below the yield stress value in a stress-strain diagram obtained from a tensile or shear test performed on the second protective layer 440. For example, the modulus of the second protective layer 440 may correspond to a value obtained by dividing stress by strain, where stress is the force applied to the second protective layer 440 per unit area and strain is the strain value per unit length. Hereinafter, the modulus of each layer may correspond to the elastic modulus and will be referred to as modulus for ease of explanation.

[0184] In one or more embodiments, in this case, although no additional protective layer such as a damping layer is further disposed or provided between the optical layer 300 and the first film layer 410, the underlying layers of the electronic device 1000-1, such as the display layer 100 or sensor layer 200, can be stably protected. With the damping layer having a thickness of approximately 100 μm, the addition of the damping layer can improve or enhance the impact resistance of the electronic device 1000-1, but the thickness of the electronic device 1000-1 may increase. According to this disclosure, by including a window 400-1 with improved or enhanced impact resistance, the electronic device 1000-1 can ensure sufficient or suitable impact resistance, thereby enabling the provision of an electronic device 1000-1 with a low thickness.

[0185] In one or more embodiments, the second protective layer 440 may further include fluorine as an additive. Then, as the water resistance of the second protective layer 440 is improved or enhanced, damage to the window 400-1 due to moisture permeability or the like can be prevented (or the extent or occurrence of damage to the window 400-1 due to moisture permeability or the like can be reduced).

[0186] In one or more embodiments, by further including a second protective layer 440, window 400-1 may not require an additional film layer. For example, even without an additional film layer between the first adhesive layer 401 and the optical layer 300, window 400-1 can ensure sufficient or suitable impact resistance and can mitigate the problem of reduced light transmittance due to the addition of a film layer. Therefore, window 400-1 can minimize or reduce the number of second film layers 420, thereby enabling the electronic device 1000-1 to provide improved or enhanced external visibility.

[0188] exist Figure 7A In the diagram, the first curve R1 shows the refractive index change based on the wavelength of the film composed of polyethylene terephthalate (PET), the second curve P1 shows the refractive index change based on the wavelength of the film composed of polyimide (P1), the third curve P2 shows the refractive index change based on the wavelength of the film composed of glass, and the fourth curve P3 shows the refractive index change based on the wavelength of the film composed of cellulose triacetate (TAC). Figure 7B The graph R11 shown illustrates the refractive index variation according to the wavelength of the film composed of polyethylene terephthalate (PET). Figure 7C The graph R12 shown illustrates the change in reflectance based on the wavelength of the film composed of polyethylene terephthalate (PET). Figures 7A to 7C The composition of polyethylene terephthalate (PET) described herein may be a comparative embodiment in which the base coating is not controlled. Hereinafter, reference will be made to... Figures 7A to 7C One or more embodiments of this disclosure will be described in more detail.

[0189] refer to Figure 7A and Figure 7B It can be observed that the film composed of polyethylene terephthalate (PET) exhibits a relatively significant refractive index deviation according to wavelength. The PET film has a refractive index of approximately 1.7 at a wavelength of approximately 450 nm and a refractive index of approximately 1.66 or less at a wavelength of approximately 650 nm. Therefore, the refractive index deviation according to wavelength of the PET film is observed to be approximately 0.04, particularly in the wavelength range from approximately 450 nm to approximately 650 nm. Furthermore, referring to the second curve P1 for the film composed of polyimide (PI), a deviation of approximately 0.15 can be observed. Figure 7C The film composed of polyethylene terephthalate (PET) has a reflectance deviation that varies in the range of about 5% to about 6%.

[0190] refer to Figure 7AThe third curve P2 and the fourth curve P3 have relatively lower deviations than the first curve R1 or the second curve P1. Referring to the third curve P2, it can be observed that the film composed of glass has a uniform (e.g., substantially uniform) refractive index of about 1.5 in the wavelength range of about 400 nm to about 700 nm, and has similar refractive indices with almost no deviation along the wavelength. Referring to the fourth curve P3, it can be observed that the film composed of TAC has a uniform (e.g., substantially uniform) refractive index of about 1.42 in the wavelength range of about 400 nm to about 700 nm, and has similar refractive indices with almost no deviation along the wavelength.

[0191] Table 1 shows the reflectance of films composed of polyethylene terephthalate (PET) and films composed of TAC, as well as the proportion of red light in the light reflected from the films. The ratio of blue light to b .

[0192] Table 1

[0193] Referring to Table 1, it can be observed that the proportion of reflected blue light b The reflectance is significantly lower in both the reflectance measured using the included specular component factor (SCI) method and the reflectance measured using the excluded specular component factor (SCE) method. The reflectance in the SCI method refers to the reflectance measured from light that includes specular reflection, while the reflectance in the SCE method refers to the reflectance measured from light that excludes specular reflection and includes only diffuse reflection (including scattered reflection). index and b The indices represent the proportions of red and blue light in the colorimeter, respectively, and increase with b. As the index decreases, the reflectivity of blue light (e.g., short-wavelength light) increases, causing the reflected light to appear blue. Referring to Table 1, it can be observed that the reflectivity in the SCI method and the SCE method are essentially similar to each other, differing by only about 0.1% in the comparative embodiment and the first embodiment, respectively. However, if we look at b... Index (e.g., when looking at b) When the index is calculated, the SCI method shows an increase of approximately 1.3 and the SCE method shows an increase of approximately 1.9. For example, it can be observed that in the first embodiment, which includes a film layer composed of TAC, the proportion of blue light reflected is relatively significantly reduced, and as a result, although the amount of reflected light itself does not change much, the proportion of short-wavelength light in the reflected light is reduced. Therefore, compared with the comparative embodiment, the phenomenon of reflected light appearing blue in the first embodiment can be reduced.

[0194] According to this disclosure, the window can be formed or provided with a film layer made of a material having a similar refractive index by wavelength. In this case, the problem of prominent reflectivity of short-wavelength light in the reflected light can be improved, such that (e.g.) the reflectivity by wavelength can be relatively or substantially uniform. Therefore, the tendency of reflected light emitted from the window to appear blue can be reduced, thereby enabling the provision of electronic devices with improved or enhanced color uniformity.

[0195] Table 2 shows the results for, such as Figure 5 The results of measuring the refractive index of each layer of the window shown are shown, as well as the reflectivity of the window.

[0196] Table 2

[0197] A comparative embodiment may be a window having the following stacked structure: a planarization layer 330 having a refractive index of about 1.54, a first adhesive layer 401 having a refractive index of about 1.47, a first film layer 410 having a refractive index of about 1.51, a second adhesive layer 402 having a refractive index of about 1.47, a second film layer 420 having a refractive index of about 1.66, and a protective layer 430 having a refractive index of about 1.52. A first embodiment may be a window in which the refractive index of the second film layer 420 is designed to be different from that of the comparative embodiment, and a second embodiment may be a window in which all layers are designed to have a refractive index substantially the same as that of the protective layer of the comparative embodiment. Referring to Table 2, the SCI reflectance, measured by including both specular and diffuse light, is relatively lower in the first and second embodiments than in the comparative embodiment. For example, as in the first embodiment, by controlling the refractive index of the second film layer 420 to have a relatively small deviation from that of adjacent layers (e.g., the second adhesive layer 402 or the protective layer 430), the reflectance of the external light itself is also reduced.

[0198] Furthermore, as in the second embodiment, by controlling that the layers constituting the window have substantially the same refractive index, the reflectivity of external light can be further reduced. For example, according to this disclosure, by reducing the difference in refractive index between adjacent layers or by designing the refractive indices to be similar to each other, the reflectivity of the window can be reduced and the display characteristics can be improved or enhanced.

[0199] In one or more embodiments, the film layer 420 according to one or more embodiments may include polyethylene terephthalate comprising an undercoat whose refractive index is controlled. The film layer 420 may include polyethylene terephthalate comprising an undercoat whose refractive index is controlled in the range of about 1.47 to about 1.66. Table 3 describes the values ​​of reflectance measured by the SCI method and the SCE method and a and b Index. In Table 3, the third embodiment may be a film layer comprising polyethylene terephthalate including an undercoat layer whose refractive index is controlled to be about 1.58, and the comparative embodiment may be a film layer comprising polyethylene terephthalate including an undercoat layer having a refractive index outside the range of about 1.47 to about 1.66.

[0200] Table 3

[0201] Referring to Table 3, the reflectance of both the comparative embodiment and film 420, measured by the SCI method, is approximately 3.8%, and their reflectance, measured by the SCE method, is approximately 0.7%, showing the same results. Conversely, it can be observed that in both the comparative embodiment and film 420, a... index and b The indices differ from one another. For example, for film layer 420, the b value measured by the SCI method... The index was approximately -3.0, which is an increase of approximately 1.4 compared to the comparative embodiment. Furthermore, for film layer 420, the b... (measured by the SCE method) The index is approximately -4.3, which is an increase of approximately 1.1 compared to the comparative embodiment. For example, since the proportion of blue light reflected from the film layer 420, which includes a base coating whose refractive index is controlled, is relatively significantly reduced, it can be observed that although the amount of reflected light itself does not change much, the proportion of short-wavelength light in the reflected light is reduced. Therefore, in the third embodiment, the phenomenon of the reflected light appearing blue can be reduced compared to the comparative embodiment. According to this disclosure, if the refractive index of the base coating is designed to be within a set or predetermined range (e.g., when the refractive index of the base coating is designed to be within a set or predetermined range), polyethylene terephthalate can be used as film layer 420, thereby enabling the provision of electronic devices with improved reflected light color and sufficient or suitable rigidity.

[0202] According to this disclosure, the electronic device can reduce the reflectivity of external light and mitigate the problem of color imbalance caused by increased reflectivity of specific light. Therefore, with improved or enhanced color appearance, the display quality of the electronic device can be enhanced.

[0203] Although one or more embodiments of this disclosure have been described, those skilled in the art will understand that one or more suitable modifications and changes can be made to the embodiments without departing from the spirit and scope of this disclosure. Therefore, the scope of this disclosure should not be limited to the embodiments described in the detailed description of this disclosure, but should be determined by the appended claims and their equivalents.
