[0001] Cross-reference to related applications

[0002] This application claims priority and benefit to Korean Patent Application No. 10-2020-0031177, filed on March 13, 2020, which is incorporated herein by reference for all purposes, as if fully set forth herein. Technical Field

[0003] Exemplary embodiments of the present invention generally relate to display devices. Background Technology

[0004] Electronic devices that provide images to users (such as smartphones, digital cameras, laptops, navigation devices, and smart TVs) typically include a display device for displaying the images. The display device generates the images and presents them to the user via a screen.

[0005] Typically, a display device includes a display panel for generating an image and an input sensing unit disposed on the display panel for sensing external input. The display panel includes a light-emitting area that generates light for displaying the image and a non-light-emitting area surrounding the light-emitting area. The input sensing unit includes multiple sensing electrodes for sensing external input. The sensing electrodes are disposed in the non-light-emitting area.

[0006] The light generated in the luminescent area travels not only toward the front of the display device, but also toward the left and right sides of the display device. Therefore, there is a need to develop a technique to improve the brightness of the front of the display device by increasing the amount of light traveling toward the front of the display device.

[0034] In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments or implementations of the present invention. As used herein, "embodiment" and "implementation" are interchangeable words that refer to a non-limiting example of an apparatus or method that employs one or more of the inventive concepts disclosed herein. However, it will be apparent to one skilled in the art that various exemplary embodiments can be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the various exemplary embodiments. In addition, various exemplary embodiments can be different from one another but not necessarily mutually exclusive. For example, a particular feature, structure, component, or characteristic described in one exemplary embodiment can be used in another exemplary embodiment or implementation without departing from the inventive concepts. Thus, the various exemplary embodiments can be practiced without such specific details or with one or more equivalent arrangements.

[0035] Unless otherwise indicated, the exemplary embodiments described are to be understood as providing examples of the variations of some of the details of the present inventive concepts that can be implemented in practice. Therefore, unless otherwise specified, features, components, modules, layers, films, panels, regions and / or aspects of various embodiments (hereinafter, individually or collectively referred to as "elements") can be combined, separated, interchanged, and / or rearranged without departing from the present inventive concepts.

[0036] The use of cross-hatching and / or shading in the drawings is generally provided to illustrate the boundaries, of the elements of the drawings. As such, neither cross-hatching nor shading is limiting of the particular materials, material properties, dimensions, proportions, or any other characteristics that can be implied by the cross-hatching or shading, unless otherwise specified. Furthermore, in the drawings, the dimensions and relative dimensions of the various elements can be exaggerated for clarity and / or descriptive purposes. While the exemplary embodiments can be implemented in different ways, a particular sequence of processes can be performed differently. For example, two processes described in succession can be executed substantially concurrently or in the reverse order as that described. Additionally, identical reference numerals have been used to designate identical elements.

[0037] When an element or layer is referred to as being “on”, “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer, or one or more intervening elements or layers can be present. In contrast, when an element or layer is referred to as being “directly on”, “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. In this regard, the term “connected” can refer to physical or electrical and / or fluid connection, with or without intervening elements. Also, the D1 axis, the D2 axis, and the D3 axis are not limited to the three axes of a rectangular coordinate system, such as the x-axis, the y-axis, and the z-axis, and can be interpreted in a broader sense. For example, the D1 axis, the D2 axis, and the D3 axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other. For the purposes of the present disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” can be interpreted to include only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as, for example, XYZ, XYY, YZ, and ZZ. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0038] Although the terms “first”, “second”, etc. can be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another. Thus, a first element discussed below could be termed a second element without departing from the teachings of the present disclosure.

[0039] Spatially relative terms, such as “beneath”, “below”, “lower”, “under”, “above”, “upper”, “on”, “directly on”, “side” (e.g., as in “sidewall”), and the like, can be used herein for ease of description to describe one element’s or feature’s relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientations depicted in the figures. For example, if a device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. In addition, the device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0040] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. 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. Furthermore, to the extent that the terms "comprises," "comprising," "includes," and / or "including" are used in the specification, they are intended to be inclusive (i.e., to state the presence of something and not to preclude the presence of additional something) and not to the exclusion of additional or other features, integers, steps, operations, elements, components, and / or groups thereof. It is also noted that, as used herein, the terms "substantially," "approximately," and other like terms are used as terms of approximation and not as terms of degree, unless otherwise indicated, and, accordingly, are utilized to account for inherent variation in measurements, calculations, and / or other aspects of a device disclosed herein that would be appreciated by those of ordinary skill in the art.

[0041] Various example embodiments are described herein with reference to cross-sectional and / or exploded illustrations that are schematic illustrations of idealized example embodiments and / or intermediate structures. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and / or tolerances, are to be expected. Thus, the example embodiments disclosed herein are not to be construed as being limited to the particular illustrated shapes of regions, etc., as such shapes are typically selected for illustrative convenience and non-limiting examples. Accordingly, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of the example embodiments disclosed herein.

[0042] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0044] Referring to Figure 1 A display device DD according to an example embodiment can have a substantially rectangular shape having a long side extending in a first direction DR1 and a short side extending in a second direction DR2 crossing the first direction DR1. However, the display device DD is not limited thereto and can have various shapes such as a circular shape or a polygonal shape.

[0045] Hereinafter, a direction substantially perpendicular to a plane defined by the first direction DR1 and the second direction DR2 is defined as a third direction DR3. As used herein, "when viewed in a plane" refers to a state of being observed in the third direction DR3.

[0046] A top surface of the display apparatus DD can be defined as a display surface DS, and can have a plane defined by the first direction DR1 and the second direction DR2. An image IM generated in the display apparatus DD can be provided to a user through the display surface DS.

[0054] An anti-reflection layer RPL can be disposed on the input sensing unit ISP. The anti-reflection layer RPL can reduce reflectivity of external light incident on the display panel DP from above the display device DD. For example, the anti-reflection layer RPL can include a phase retarder and / or a polarizer.

[0127] Figure 8 is a cross-sectional view taken along a line I-I' of Figure 7 .

[0128] Referring to Figure 8 , an insulating layer IOL can be disposed on a thin film encapsulation layer TFE. The insulating layer IOL can be an inorganic layer.

[0131] Figure 9 is an enlarged view of a second area AA2 of Figure 6 .

[0132] In Figure 9 , light emitting areas PA1, PA2, and PA3 are exemplarily illustrated together with the first sensor SP1 and the second sensor SP2.

[0133] Referring to Figure 9The light emitting areas PA can be disposed on the first diagonal direction DDR1 and the second diagonal direction DDR2. The first branch BP1 and the second branch BP2 can overlap with the non-light emitting areas NPA between the light emitting areas PA. More specifically, the first sensor SP1 and the second sensor SP2 can be disposed in the non-light emitting areas NPA. Because the first sensor SP1 and the second sensor SP2 are disposed in the non-light emitting areas NPA, light generated in the light emitting areas PA1, PA2, and PA3 can be normally emitted without being affected by the first sensor SP1 and the second sensor SP2.

[0134] The light emitting areas PA can include a plurality of first light emitting areas PA1 displaying red, a plurality of second light emitting areas PA2 displaying green, and a plurality of third light emitting areas PA3 displaying blue. Each of the second light emitting areas PA2 has a smaller surface area than each of the first light emitting areas PA1 when viewed in a planar view, and each of the third light emitting areas PA3 has a larger surface area than each of the first light emitting areas PA1.

[0135] The light emitting areas PA1, PA2, and PA3 can each have a substantially rhombus shape. The touch openings TOP can overlap with the light emitting areas PA1, PA2, and PA3. Each of the touch openings TOP can have a substantially rhombus shape corresponding to the shape of the light emitting areas PA1, PA2, and PA3.

[0136] The reflection pattern RPT can be disposed adjacent to the light emitting areas PA in the touch openings TOP when viewed in a planar view. The reflection pattern RPT can overlap with the non-light emitting areas NPA and can be disposed between the light emitting areas PA and the second conductive pattern CNT2.

[0137] The reflection pattern RPT can be disposed adjacent to edges of the light emitting areas PA and can extend along the edges of the light emitting areas PA. For example, the reflection pattern RPT can extend in the first diagonal direction DDR1 or the second diagonal direction DDR2 along the edges of the light emitting areas PA.

[0138] The reflection pattern RPT can include a plurality of first reflection patterns RPT1 adjacent to the first light emitting areas PA1, a plurality of second reflection patterns RPT2 adjacent to the second light emitting areas PA2, and a plurality of third reflection patterns RPT3 adjacent to the third light emitting areas PA3.

[0139] The first reflective pattern RPT1 can be configured to be adjacent to the edge of the first luminous region PA1 and can extend along the edge of the first luminous region PA1. The second reflective pattern RPT2 can be configured to be adjacent to the edge of the second luminous region PA2 and can extend along the edge of the second luminous region PA2. The third reflective pattern RPT3 can be configured to be adjacent to the edge of the third luminous region PA3 and can extend along the edge of the third luminous region PA3.

[0140] The first length LT1 of each of the first reflective patterns RPT1 in its extension direction, the second length LT2 of each of the second reflective patterns RPT2 in its extension direction, and the third length LT3 of each of the third reflective patterns RPT3 in its extension direction may be different. The extension direction of each of the first reflective patterns RPT1, the second reflective patterns RPT2, and the third reflective patterns RPT3 may be defined as a first diagonal direction DDR1 or a second diagonal direction DDR2.

[0141] The first reflective pattern RPT1, the second reflective pattern RPT2, and the third reflective pattern RPT3 may have lengths corresponding to the first luminous region PA1, the second luminous region PA2, and the third luminous region PA3, respectively. For example, the first length LT1 may be longer than the second length LT2 and shorter than the third length LT3.

[0142] Figure 10 Is Figure 9 An enlarged view of one of the luminous areas shown and the reflective pattern set around that luminous area. Figure 11 It is along Figure 10 The sectional view taken from line II-II'.

[0143] For example, Figure 10 The luminescent region PA and the reflective pattern RPT shown can be respectively Figure 9 The first light-emitting area PA1 and the first reflective pattern RPT1. Specifically, the light-emitting area PA can be one of the first light-emitting areas PA1 disposed in the touch opening TOP defined in the first sensor SP1. Although Figure 10 An exemplary illustration shows a reflective pattern RPT set around the luminescent region PA, but... Figure 9 Other reflective patterns shown in the RPT can also have the same... Figure 10 The reflective pattern shown has essentially the same configuration as the RPT.

[0144] Reference Figure 10 The light-emitting region PA may include multiple sides SD that define the edges of the light-emitting region PA. For example, a light-emitting region PA with a generally rhomboid shape may include four sides SD. The number of sides SD may vary depending on the shape of the light-emitting region PA.

[0145] The reflection patterns RPT can be disposed to surround the light emission area PA. The reflection patterns RPT can be spaced apart from each other and disposed to respectively correspond to the sides SD of the light emission area PA. For example, four reflection patterns RPT can be disposed to respectively adjoin four sides SD.

[0146] Although the reflection patterns RPT according to the illustrated exemplary embodiment are shown as being spaced apart from each other and disposed adjacent to the light emission area PA, the inventive concept is not limited thereto. For example, in some exemplary embodiments, a single reflection pattern RPT can extend along an edge of the light emission area PA to surround the light emission area PA.

[0147] Referring to Figure 10 and Figure 11 The reflection patterns RPT can be disposed in the non-light emission area NPA. Each of the reflection patterns RPT can include a first sub-reflection pattern SPT1 and a second sub-reflection pattern SPT2 disposed below the first sub-reflection pattern SPT1. The first sub-reflection pattern SPT1 can substantially overlap the entire second sub-reflection pattern SPT2 when viewed in a plan view.

[0148] The second sub-reflection pattern SPT2 can be disposed on the insulating layer IOL, and a first insulating layer TC-IL1 can be disposed on the second sub-reflection pattern SPT2. Thus, the second sub-reflection pattern SPT2 can be disposed on the same layer as the first conductive pattern CNT1 described above. The second sub-reflection pattern SPT2 can be formed by simultaneously patterning the second sub-reflection pattern SPT2 and the first conductive pattern CNT1 with the same material as forming the first conductive pattern CNT1. The second sub-reflection pattern SPT2 can include a metallic material capable of reflecting light.

[0149] The first sub-reflection pattern SPT1 can be disposed on the first insulating layer TC-IL1, and a second insulating layer TC-IL2 can be disposed on the first sub-reflection pattern SPT1. Thus, the first sub-reflection pattern SPT1 can be disposed on the same layer as the second conductive pattern CNT2. The first insulating layer TC-IL1 can be disposed between the first sub-reflection pattern SPT1 and the second sub-reflection pattern SPT2.

[0150] The first sub-reflection pattern SPT1 can extend from the second conductive pattern CNT2. The first sub-reflection pattern SPT1 can be formed by simultaneously patterning the first sub-reflection pattern SPT1 and the second conductive pattern CNT2 with the same material as forming the second conductive pattern CNT2. The first sub-reflection pattern SPT1 can include a metallic material capable of reflecting light.

[0151] One side surface OS adjacent to (or facing) the light emitting area PA of each of the reflection patterns RPT can have a tilted surface. For example, one side surface OS of the first and second sub-reflection patterns SPT1 and SPT2 adjacent to the light emitting area PA can have a tilted surface. The other side surface of the first and second sub-reflection patterns SPT1 and SPT2 opposite to the one side surface OS of the first and second sub-reflection patterns SPT1 and SPT2 can also have a tilted surface.

[0152] One side surface OS can form a tilt angle θs of greater than about 60 degrees and less than about 90 degrees with a bottom surface of the first and second sub-reflection patterns SPT1 and SPT2, respectively, and more particularly, can form a tilt angle θs of from about 70 degrees to about 80 degrees. The tilt angle θs of the one side surface OS of the first and second sub-reflection patterns SPT1 and SPT2 can be the same, however, the inventive concept is not limited thereto. For example, in some exemplary embodiments, the tilt angle θs of the one side surface OS of the first and second sub-reflection patterns SPT1 and SPT2 can be different from each other.

[0153] The first thickness TH1 of the first sub-reflection pattern SPT1 can be the same as a thickness of the second conductive pattern CNT2. The second thickness TH2 of the second sub-reflection pattern SPT2 can be the same as a thickness of the first conductive pattern CNT1. The first thickness TH1 can be greater than the second thickness TH2. For example, the first thickness TH1 can be about to about and the second thickness TH2 can be about to about However, the inventive concept is not limited thereto, and in other exemplary embodiments, the first thickness TH1 can be the same as the second thickness TH2.

[0154] The first sub-reflection pattern SPT1 can be connected to the second sub-reflection pattern SPT2 through a contact hole RP-CH defined in the first insulating layer TC-IL1. The contact hole RP-CH can be provided as a single contact hole and can extend in a direction in which each of the first and second sub-reflection patterns SPT1 and SPT2 extends. The contact hole RP-CH can have the same width as a top surface of the second sub-reflection pattern SPT2. Accordingly, the contact hole RP-CH can increase a contact area between the first and second sub-reflection patterns SPT1 and SPT2.

[0155] The first sub-reflective pattern SPT1 can extend from and connect to the second conductive pattern CNT2. Therefore, a sensing signal applied to the second conductive pattern CNT2 can be applied to both the first and second sub-reflective patterns SPT1 and SPT2. In this way, the first and second sub-reflective patterns SPT1 and SPT2 can be used as sensing electrodes.

[0156] A portion of the light L1 generated by the OLED can travel in the upward direction to be emitted in the upward direction of the display device DD. Another portion of the light L2 generated by the OLED can form a predetermined emission angle with the third direction DR3 and travel toward the side surface of the display device DD.

[0157] Light L2 can travel in each of the reflective patterns RPT. The reflective patterns RPT can reflect the light L2 provided from the emitting region PA in an upward direction. For example, light L2 can be reflected upward by one side surface OS of the first sub-reflective pattern SPT1 and the second sub-reflective pattern SPT2. Because one side surface OS of the first sub-reflective pattern SPT1 and the second sub-reflective pattern SPT2 has a sloping surface, more light L2 can travel in the upward direction. Therefore, the front brightness of the display device DD can be improved.

[0158] When the reflective pattern RPT is not used and a separate refractive pattern for refracting light L2 is set in the input sensing unit ISP, the thickness of the display device DD can be increased. Furthermore, touch sensitivity may be degraded due to the refractive pattern, which includes insulating material.

[0159] Since the display device DD according to the exemplary embodiment includes a reflective pattern RPT, which can be formed using the first conductive pattern CNT1 and the second conductive pattern CNT2 in the input sensing unit ISP, the use of a separate refractive pattern can be avoided. In this way, the thickness of the display device DD can be reduced, and the degradation of touch sensitivity due to the refractive pattern can be prevented.

The first sub-reflection pattern SPT1_1 can be connected to the second sub-reflection pattern SPT2 through a single contact hole RP-CH2.

[0167]

[0168] ​​​​​​​​​​The second sub-reflection pattern SPT2 can reflect the light L2 provided from the light emitting area PA to allow the light L2 to travel in the upward direction. The light L2 can be reflected toward the upward direction by one side surface OS of the second sub-reflection pattern SPT2.

[0170] Figure 15 A plan view corresponding to Figure 10 is illustrated. Hereinafter, the reflection pattern RPT_3 will be described focusing on a configuration different from that of the reflection pattern RPT illustrated in Figure 16 and Figure 11 A cross-sectional view corresponding to Figure 10 and Figure 11 The reflection pattern RPT_3 according to the illustrated exemplary embodiment can include a first sub-reflection pattern SPT1_2 and a second sub-reflection pattern SPT2 disposed below the first sub-reflection pattern SPT1_2.

[0171] Referring to Figure 15 and Figure 16 , each of the reflection patterns RPT_3 can include a first sub-reflection pattern SPT1_2 and a second sub-reflection pattern SPT2 disposed below the first sub-reflection pattern SPT1_2.

[0172] Unlike the first sub-reflection pattern SPT1 described above, the first sub-reflection pattern SPT1_2 according to the illustrated exemplary embodiment can not extend from the second conductive pattern CNT2. The first sub-reflection pattern SPT1_2 can be spaced apart from and insulated from the second conductive pattern CNT2.

[0173] The first sub-reflection pattern SPT1_2 can be connected to the second sub-reflection pattern SPT2 through the contact hole RP-CH. The light L2 can be reflected by the first sub-reflection pattern SPT1_2 and one side surface OS of the second sub-reflection pattern SPT2 to travel in the upward direction.

[0175] Figure 17 A plan view corresponding to Figure 10 is illustrated. Hereinafter, the reflection pattern RPT_4 will be described focusing on a configuration different from that of the reflection pattern RPT illustrated in Figure 10 .

[0176] Referring to Figure 17The light emitting area PA can include first sides SD1 extending in the second diagonal direction DDR2 and facing each other in the first diagonal direction DDR1 and second sides SD2 extending in the first diagonal direction DDR1 and facing each other in the second diagonal direction DDR2. The first sides SD1 and the second sides SD2 can define edges of the light emitting area PA.

[0177] The reflection patterns RPT_4 can be disposed adjacent to the first sides SD1, respectively. The reflection patterns RPT_4 can not be disposed near the second sides SD2. The first sub-reflection patterns SPT1 and the second sub-reflection patterns SPT2 of each of the reflection patterns RPT_4 can have the same configuration as the first sub-reflection patterns SPT1 and the second sub-reflection patterns SPT2 shown in FIGS. 1A and 1B.

[0179] Figure 18 A plan view corresponding to Figure 10 is exemplarily illustrated, and Figure 19 A cross-sectional view corresponding to Figure 11 is exemplarily illustrated. Hereinafter, the reflection pattern RPT_5 will be described focusing on a configuration different from that of the reflection pattern RPT shown in FIGS. 1A and 1B. Figure 10 Figure 11 Referring to and

[0180] , the reflection pattern RPT_5 can extend from the second conductive pattern CNT2 and can extend along the edges of the light emitting area PA. The reflection pattern RPT_5 can be disposed adjacent to the sides SD of the light emitting area PA, respectively.

[0181] except that the reflection pattern RPT_5 can not include the second sub-reflection pattern SPT2. Figure 10 Figure 11
