[0002] This application claims priority and benefit to Korean Patent Application No. 10-2023-0013741, filed on February 1, 2023, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to light-emitting display devices including light-emitting diodes (LEDs). Background Technology

[0004] Emitting-light display devices can include light-emitting diodes (LEDs) corresponding to pixels, and images can be displayed by controlling the brightness of each LED. Unlike light-receiving display devices such as liquid crystal displays, emitting-light display devices do not require a light source such as a backlight, thus reducing thickness and weight. Furthermore, emitting-light display devices possess characteristics such as high brightness, high contrast, high color reproduction, and high response speed, enabling the display of high-quality images.

[0005] Due to these advantages, light-emitting display devices are used in a variety of electronic devices, such as mobile devices (e.g., smartphones and tablets), monitors and televisions, and have also gained attention as display devices for automobiles. Utility Model Content

[0042] Some aspects of this disclosure can be more readily understood by referring to the detailed description and accompanying drawings of the embodiments. The embodiments will be described in more detail below with reference to the accompanying drawings. However, the described embodiments may have various modifications and may be implemented in different forms, and should not be construed as being limited to the embodiments shown herein. Furthermore, each of the features of the various embodiments of this disclosure may be combined partially or entirely with each other, and various technical interlocks and drives are possible. Each embodiment may be implemented independently of each other or may be implemented together in association. The described embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey aspects of this disclosure to those skilled in the art, and it should be understood that this disclosure covers all modifications, equivalents, and substitutions within the spirit and technical scope of this disclosure. Therefore, processes, elements, and techniques not essential for a person of ordinary skill in the art to fully understand aspects of this disclosure may not be described.

[0043] Unless otherwise stated, the same reference numerals, designations, or combinations thereof denote the same elements throughout the drawings and written description, and therefore their description will not be repeated. Furthermore, portions not related to or irrelevant to the description of the embodiments may be omitted to make the description clear.

[0044] In the accompanying drawings, the relative dimensions of elements, layers, and regions may be exaggerated for clarity. Furthermore, crosshairs and / or shading are typically used in the drawings to clarify boundaries between adjacent elements. Therefore, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for particular materials, material properties, dimensions, scale, commonalities between the elements shown, and / or any other characteristics, properties, or attributes of the elements, unless otherwise stated.

[0045] Various embodiments are described herein with reference to schematic illustrations and / or cross-sectional views of intermediate structures as examples of implementations. Thus, variations in shape as a result of, for example, manufacturing techniques and / or tolerances, are to be expected. Furthermore, the specific structural or functional descriptions disclosed herein are solely for the purpose of describing embodiments according to the concept of this disclosure. Therefore, the embodiments disclosed herein should not be construed as limited to the shapes shown, but rather include shape deviations caused, for example, by manufacturing processes.

[0046] For example, an injection region shown as rectangular typically has rounded or curved features at its edges and / or a gradient of injection concentration, rather than a binary variation from the injection region to the non-injection region. Similarly, a buried region formed by injection can result in some injection in the region between the buried region and the surface through which the injection occurs.

[0047] Therefore, the areas shown in the accompanying drawings are schematic in nature, and their shapes are not intended to represent the actual shape of the areas of the device, nor are they intended to be limiting. Furthermore, as those skilled in the art will recognize, the described embodiments can be modified in various ways without departing entirely from the spirit or scope of this disclosure.

[0048] In the detailed description, numerous specific details are set forth for illustrative purposes to provide a thorough understanding of the various implementations. However, it will be apparent that various implementations can be practiced without these specific details or with one or more equivalent arrangements.

[0049] For ease of explanation, spatial relative terms such as “below,” “under,” “lower,” “lower side,” “below,” “above,” “upper,” and “upper side” may be used herein to describe the relationship between one element or feature and another element(s) shown in the figures. It should be understood that, in addition to the orientation shown in the figures, spatial relative terms are intended to also include different orientations of the device in use or operation. For example, if the device in the figures is flipped, the element or feature described as “below,” “under,” or “below” other elements or features will be oriented “above” other elements or features. Thus, the exemplary terms “below” and “below” can include both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly. Similarly, when a first part is described as being arranged “on” a second part, this means that the first part is arranged above or below the second part, and not limited to the upper side of the second part based on the direction of gravity.

[0050] Furthermore, the phrase "in a plan view" means when viewing a portion of the object from above, and the phrase "in a schematic sectional view" means when viewing a schematic section obtained by vertically cutting the portion of the object from the side. The terms "overlapping" or "overlapping" mean that the first object may be above or below the second object or on one side of the second object, and conversely, the second object may be above or below the first object or on one side of the first object. Additionally, the term "overlapping" may include layer, stack, facing or oriented, extending throughout, covering or partially covering, or any other suitable term that will be recognized and understood by one of ordinary skill in the art. The expression "non-overlapping" may include meanings such as "spaced apart" or "side by side" or "offset," and any other suitable equivalent that will be recognized and understood by one of ordinary skill in the art. The terms "facing" and "oriented" may mean that the first object may be directly or indirectly opposite the second object. In cases where a third object is located between the first and second objects, the first and second objects may be understood as indirectly opposite each other, although still facing each other.

[0051] It should be understood that when a component, layer, region, or assembly is referred to as being "formed on," "connected to," or (operably or communicatively) coupled to another component, layer, region, or assembly, it can be directly formed on, directly on, directly connected to, or directly coupled to another component, layer, region, or assembly; or indirectly formed on, indirectly on, indirectly connected to, or indirectly coupled to another component, layer, region, or assembly, such that one or more intervening components, layers, regions, or assemblies may exist. Furthermore, this can collectively refer to direct or indirect connections or linkages, as well as integral or non-integral connections or linkages. For example, when a layer, region, or assembly is referred to as being "electrically connected" or "electrically coupled" to another layer, region, or assembly, it can be directly electrically connected to or directly electrically coupled to another layer, region, or assembly, or an intervening layer, region, or assembly may exist. However, " "Direct connection / direct connection" or "directly on..." means that one component is directly connected to or directly connected to another component, or directly on another component, without any intermediate components. Furthermore, in this specification, when a portion of a layer, film, region, plate, etc., is formed on another portion, the forming direction is not limited to the upper direction, but includes forming the portion on a side surface or in the lower direction. Conversely, when a portion of a layer, film, region, plate, etc., is formed "below" another portion, this includes not only the case where the portion is "directly below" the other portion, but also the case where there is another portion between the portion and the other portion. Similarly, other expressions describing the relationship between components (such as "between", "directly between", or "adjacent to" and "directly adjacent to") can be interpreted similarly. Furthermore, it should be understood that when an element or layer is referred to as being "between" two elements or layers, it can be the only element or layer between the two elements or layers, or there can be one or more intervening elements or layers.

[0052] For the purposes of this disclosure, when following an element of a list, expressions such as “at least one of…”, “any one of…”, or “one or more of…” modify the elements of the entire list rather than individual elements within the list. For example, “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 as: only X; only Y; only Z; any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ; or any variations thereof. Similarly, expressions such as “at least one of A and B” can include A, B, or A and B. As used herein, “or” generally means “and / or”, and the term “and / or” includes any and all combinations of one or more of the related listed items. For example, expressions such as “A and / or B” can include A, B, or A and B. Similarly, when following / before an element of a list, expressions such as “multiple,” “one of…,” and other prepositional phrases modify the elements of the entire list rather than individual elements within the list.

[0053] It should be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part. Therefore, without departing from the spirit and scope of this disclosure, the first element, component, region, layer, or part described below may be referred to as the second element, component, region, layer, or part. The description of an element as a “first” element may not require or imply the presence of a second element or other elements. The terms “first,” “second,” etc., may also be used herein to distinguish elements of different categories or groups. For the sake of brevity, the terms “first,” “second,” etc., may respectively represent “first category (or first set),” “second category (or second set),” etc.

[0054] In this example, the x-axis, y-axis, and / or z-axis are not limited to the three axes of a rectangular coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other. The same applies to the first direction, the second direction, and / or the third direction.

[0055] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. As used herein, the singular forms “a” and “an” are also intended to include the plural forms, and the plural forms are also intended to include the singular forms, unless the context clearly indicates otherwise. It will also be understood that, when used in this specification, the terms “comprising,” “including,” “having,” “possessing,” “including,” and “comprise” designate 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.

[0056] As used herein, the terms “substantially,” “about,” “approximately,” and similar terms are used as approximate terms rather than terms of degree and are intended to account for inherent deviations in measured or calculated values ​​that would be recognized by one of ordinary skill in the art. As used herein, “about” or “approximately” includes the stated value and means within an acceptable range of deviation for a particular value as determined by one of ordinary skill in the art, taking into account the measurement in question and the error associated with the measurement of a particular quantity (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5% of the stated value. Furthermore, when describing embodiments of this disclosure, the use of “may” refers to “one or more embodiments of this disclosure.”

[0057] First, refer to Figure 1 and Figure 2 Describes a light-emitting display device according to one or more embodiments.

[0058] Figure 1 This is a perspective view schematically showing a light-emitting display device according to one or more embodiments. Figure 2 It is a cross-sectional view of a pixel of a light-emitting display device according to one or more embodiments.

[0060] The display panel 10 may include a display area DA corresponding to a screen on which an image is displayed, and a non-display area NA with circuitry and / or signal lines positioned for generating and / or transmitting various signals applied to the display area DA. The non-display area NA may surround the display area DA.

[0061] In the display area DA of the display panel 10, pixels PX can be arranged in a matrix. Furthermore, signal lines such as gate lines (also called scan lines), data lines, and drive voltage lines can be arranged in the display area DA. Each pixel PX can be connected to the gate lines, data lines, drive voltage lines, etc., and can receive gate signals (also called scan signals), data voltages, and drive voltages (also called first power voltages or high-potential power voltages) from these signal lines. A pixel PX can be the smallest unit capable of displaying contrast. One pixel PX can correspond to one light-emitting area, and the planar shape of the pixel PX can be defined by the corresponding light-emitting area. Each pixel PX can display any of the primary colors such as red, green, and blue. Pixel PX can be implemented using light-emitting elements (such as light-emitting diodes (LEDs)) and pixel circuitry connected to the light-emitting elements.

[0062] Touch sensors used to detect user contact and / or non-contact touch can be located in the display area DA. Although the display area DA is shown as a roughly quadrilateral, it can have various shapes other than quadrilaterals, such as polygons, circles, or ellipses.

[0063] In the non-display area NA of the display panel 10, a pad portion PP may be positioned, in which pads for receiving signals from the outside of the display panel 10 are arranged. The pad portion PP may be longitudinally positioned along one edge of the display panel 10 in a first direction x. A flexible printed circuit film 20 may be bonded to the pad portion PP, and the pads of the flexible printed circuit film 20 may be electrically connected to the pads of the pad portion PP.

The driving unit includes a data driver that applies data voltages to data lines, a gate driver that applies gate signals to gate lines, and a signal controller that controls the data driver and the gate driver. Pixel PX can receive data voltages according to a timing sequence (e.g., a predetermined timing) based on the gate signals generated by the gate driver. The gate driver may be integrated into the display panel 10 and may be located on at least one side of the display area DA. The data driver and signal controller may be provided as an integrated circuit chip (also referred to as a driver IC chip) 30, and the integrated circuit chip 30 may be mounted in the non-display area NA of the display panel 10. The integrated circuit chip 30 may be mounted on a flexible printed circuit film 20, etc., and may be electrically connected to the display panel 10.

[0065] refer to Figure 2 An example describing the cross-sectional structure of a light-emitting display device stacked upwards on a third party.

[0066] According to one or more embodiments, the light-emitting display device may include a substrate 110.

[0067] The substrate 110 may include a plastic material such as polyimide, or it may include glass. The substrate 110 may include a flexible material that can be bent or folded, and may be single-layered or multi-layered.

[0068] In one or more embodiments, a buffer layer comprising inorganic or organic insulating material may also be positioned on the substrate 110.

[0069] A semiconductor AC may be positioned on the substrate 110. The semiconductor AC may include conductive regions and channel regions. The semiconductor AC may include semiconductor materials, such as amorphous silicon, polycrystalline silicon, or oxide semiconductors.

[0070] A gate insulating layer 111 may be positioned on the semiconductor AC. The gate insulating layer 111 may have a single-layer or multi-layer structure and may include an inorganic insulating material.

[0071] A gate electrode GE may be positioned on the gate insulating layer 111. The gate electrode GE may overlap with the channel region of the semiconductor AC. The gate electrode GE may have a single-layer or multi-layer structure and may include metallic materials such as molybdenum (Mo), aluminum (Al), copper (Cu), and / or titanium (Ti).

[0072] An interlayer insulating layer 112 may be positioned on the gate electrode GE. The interlayer insulating layer 112 may have a single-layer or multi-layer structure and may include inorganic insulating materials or organic insulating materials.

[0073] An active electrode SE and a drain electrode DE can be positioned on the interlayer insulating layer 112. The source electrode SE and the drain electrode DE can have a single-layer or multi-layer structure and can include aluminum (Al), platinum (Pt), palladium (Pd), silver (Ag), magnesium (Mg), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), calcium (Ca), molybdenum (Mo), titanium (Ti), tungsten (W), and / or copper (Cu).

[0074] The source electrode SE and drain electrode DE can be electrically connected to each conductive region of the semiconductor AC through corresponding holes in the interlayer insulating layer 112 and the gate insulating layer 111.

[0075] A transistor T is composed of a semiconductor AC, a gate electrode GE, a source electrode SE, and a drain electrode DE.

[0076] A passivation layer 113 may be positioned on the source electrode SE and the drain electrode DE. The passivation layer 113 may include an organic insulating material, such as various polymer resins.

[0077] A first electrode PE may be positioned on the passivation layer 113. The first electrode PE may have a single-layer or multi-layer structure and may include at least one of a metal and a transparent conductive oxide film (such as IZO, IGZO and ITZO).

[0078] The first electrode PE is located in each pixel PX and is separated from and insulated from the first electrode PE of the neighboring pixel PX.

[0079] The first electrode PE can be electrically connected to the drain electrode DE of the transistor T through the holes in the passivation layer 113. The first electrode PE can receive the output current to be transferred from the drain electrode DE to the light-emitting unit TLEU.

[0080] An insulating layer 114 may be positioned on the passivation layer 113. The insulating layer 114, also referred to as a dam layer or pixel defining layer (PDL), includes / defined a pixel opening 114a overlapping the first electrode PE. In a plan view of the pixel PX described later, the shape of the pixel PX may be defined by the shape of the pixel opening 114a. The insulating layer 114 may comprise an organic insulating material, such as polyimide, polyamide, acrylic resin, benzocyclobutene, and phenolic resin. According to one or more embodiments, the insulating layer 114 may also comprise a black pigment.

[0081] The light-emitting unit TLEU can be located on the first electrode PE.

[0082] The light-emitting unit TLEU consists of multiple layers. For example... Figure 2 As shown, the light-emitting unit TLEU includes a layer located within each pixel opening 114a of the insulating layer 114. In addition to being inside the pixel opening 114a, the light-emitting unit TLEU may also include a layer located on the upper surface of the insulating layer 114 outside the pixel opening 114a.

[0087] An encapsulation layer 115 for sealing and protecting the light-emitting diode (LED) 120 may be positioned above it. According to one or more embodiments, an encapsulation substrate may be positioned instead of the encapsulation layer 115.

[0088] Figure 3 This is a top view showing the pixel arrangement in a light-emitting display device according to one or more embodiments.

[0089] refer to Figure 3 The diagram illustrates four adjacent pixel regions PA and pixels PXa, PXb, and PXc located within each pixel region PA. Pixel regions PA may be repeatedly located in the first direction x and the second direction y, and for example, pixel regions PA may be quadrilaterals arranged repeatedly in a grid.

[0090] Pixels PXa, PXb, and PXc may include a first pixel PXa, a second pixel PXb, and a third pixel PXc. The first pixel PXa, the second pixel PXb, and the third pixel PXc can display different corresponding colors. For example, one of the first pixel PXa and the second pixel PXb can display red, the other can display green, and the third pixel PXc can display blue. Alternatively, one of the first pixel PXa and the second pixel PXb can display blue, the other can display red, and the third pixel PXc can display green. The first pixel PXa, the second pixel PXb, and the third pixel PXc located in a pixel region PA can constitute a unit pixel PU.

[0091] Each quadrilateral region defined by a first line L1 extending in the first direction x and a second line L2 extending in the second direction y can correspond to a pixel region PA. The pixel region PA can be a quadrilateral with a first width in the first direction x and a second width in the second direction y. As pixel density increases, the size of each pixel region PA can decrease.

[0092] A unit pixel (PU) can be located within each pixel region (PA). Therefore, a pixel region (PA) can correspond to an area where one unit pixel (PU) is located. Pixel density can refer to the number of unit pixel (PU) per inch. A unit pixel (PU) can consist of a first pixel (PXa), a second pixel (PXb), and a third pixel (PXc). Within each pixel region (PA), at least three pixel circuits for driving the first pixel (PXa), the second pixel (PXb), and the third pixel (PXc) can also be located.

[0093] The third pixel PXc includes a first segmented pixel PXc1 and a second segmented pixel PXc2 positioned within the pixel region PA and spaced apart along a first diagonal direction dr1. The first segmented pixel PXc1 and the second segmented pixel PXc2 display the emitted color of the third pixel PXc. In this way, to display the same color, the first segmented pixel PXc1 and the second segmented pixel PXc2 can be driven by the same signal. This means that the same signal can be provided while connected to the same pixel circuit, or the same signal can be provided while connected to separate circuits. Because the first segmented pixel PXc1 and the second segmented pixel PXc2 are pixels displaying the same color within a single pixel unit PU, the first segmented pixel PXc1 and the second segmented pixel PXc2 can be driven according to the signal of the image to be displayed by the first segmented pixel PXc1 and the second segmented pixel PXc2 included in the pixel unit PU. This third pixel PXc can be a pixel used to emit light of any color. That is, as described above, any pixel displaying red, blue, and green can be a third pixel PXc, that is, a pixel that is divided into a first segmentation pixel PXc1 and a second segmentation pixel PXc2, and there are no particular restrictions.

[0094] On the second diagonal direction dr2, which intersects the first diagonal direction dr1, the first pixel PXa and the second pixel PXb are positioned spaced apart from each other. Therefore, the first segmentation pixel PXc1 and the second segmentation pixel PXc2 can be positioned so that they are not adjacent to each other in the horizontal direction (i.e., the first direction x) or the vertical direction (i.e., the second direction y). Furthermore, the first segmentation pixel PXc1 is adjacent to the second pixel PXb in the horizontal direction and to the first pixel PXa in the vertical direction. Conversely, the second segmentation pixel PXc2 is adjacent to the first pixel PXa in the horizontal direction and to the second pixel PXb in the vertical direction.

[0095] like Figure 3 As shown, in one or more embodiments, the first pixel PXa and the second pixel PXb can have rectangular shapes (e.g., approximately rectangular shapes), and the first segmentation pixel PXc1 and the second segmentation pixel PXc2 can have octagonal shapes (e.g., approximately octagonal shapes). For example, the shapes of the first pixel PXa and the second pixel PXb can be substantially similar, and the shapes of the first segmentation pixel PXc1 and the second segmentation pixel PXc2 can be substantially similar. Furthermore, the second pixel PXb can be larger than the first pixel PXa. However, pixel PX (see...) Figure 1 The size and shape of the pixel are not limited to this, and can be appropriately selected by considering factors such as aperture ratio, lifetime, and the color of each pixel in the pixel PX. Furthermore, when... Figure 3When the first segmentation pixel PXc1 and the second segmentation pixel PXc2 shown are formed into a shape that is elongated in one direction, they are adapted to have a form in which the length directions of each of the first segmentation pixel PXc1 and the second segmentation pixel PXc2 are perpendicular to each other, and for example, the shape of the second segmentation pixel PXc2 can be substantially similar to the shape of the first segmentation pixel PXc1 rotated 90 degrees.

[0096] Multiple pixel regions PA can be repeatedly located in the first direction x and the second direction y. As a result, pixels PX included in each pixel region PA can be continuously located in the first direction x and the second direction y. For example, as... Figure 3 As shown, in the first row of pixel rows extending in the first direction x, the first segmentation pixel PXc1 and the second pixel PXb are positioned alternately, and in the second row adjacent to this first row, the first pixel PXa and the second segmentation pixel PXc2 are positioned alternately. At this time, the first segmentation pixel PXc1 in the first row is positioned so as not to overlap with the second segmentation pixel PXc2 in the second row relative to the second direction y. Therefore, in the first column of pixel columns extending in the second direction y, the first segmentation pixel PXc1 and the first pixel PXa are positioned alternately, and in the second column adjacent to the first column, the second pixel PXb and the second segmentation pixel PXc2 are positioned alternately. Thus, although the pixels PX are arranged continuously, the driving of each pixel PX is performed independently by distinguishing each pixel PX for each unit pixel PU as described above.

[0097] In this way, by dividing and positioning any of the three color pixels included in the unit pixel PU, all of the pixels PX can have shapes with small differences in horizontal and vertical ratios. If the shape of the pixel PX has small differences in horizontal and vertical ratios, defects can be reduced and the aperture ratio can be increased when applying the fine metal mask (FMM) used to form the pixel PX and when the aperture shape is the same as that of the pixel PX. For example, when forming medium or large display panels, there are cases where the fine metal mask may be appropriately rotated 90 degrees from the initial arrangement direction (normal arrangement) to another arrangement (rotated arrangement). Even in this case, deposition can be performed with the same quality as when applying the normal arrangement without mask deformation.

[0098] In the following text, reference will be made to Figures 4 to 8 To describe the above effects in more detail.

[0099] Figure 4 , Figure 5 and Figure 6These are top views showing examples of masks used in the manufacture of a light-emitting display device according to one or more embodiments. Figure 7 This is a top view showing the pixel arrangement in a light-emitting display device according to a comparative example. Figure 8 This is a top view showing an example of a mask used in manufacturing a light-emitting display device according to a comparative example.

[0100] first, Figure 4 It shows in Figure 3 A first mask Ma is used during the deposition of the first pixel PXa. Multiple first openings Ha corresponding to the shape of the first pixel PXa are formed in the first mask Ma. During deposition, the first mask Ma... Figure 4 The up and down directions shown (i.e., in) Figure 4 The material (in the direction of the arrow shown) is pulled and subjected to tensile force. However, when the first mask Ma is properly rotated 90 degrees, only the first mask Ma rotates, and the tensile force is applied in the same way, thus applying a tensile force in the opposite direction to the first mask Ma based on the initial first mask Ma. Some of the deformation of the opening or the lip between the openings occurs due to the tensile force. Because the direction of the tensile force changes with rotation, the shape of the opening changes when this deformation occurs in different directions, which may be undesirable. However, as Figure 4 As shown, in the case of the first pixel PXa, the shape and arrangement of the first opening Ha remain substantially the same before and after rotation, so there is no risk due to this change in the direction of the tensile force.

[0101] at the same time, Figure 5 It shows in Figure 3 The second mask Mb is used during the deposition of the second pixel PXb. Multiple second openings Hb corresponding to the shape of the second pixel PXb are formed in the second mask Mb. Even with the second mask Mb, when rotated 90 degrees, as... Figure 5 As shown, the shape and arrangement of the second opening Hb are substantially the same before and after rotation, and there is no risk of change in the direction of the stretching force for the second pixel PXb.

[0102] Figure 6 It shows in Figure 3 The third mask Mc is used in the deposition of the third pixel PXc. Multiple third openings Hc corresponding to the shape of the third pixel PXc are formed in the third mask Mc. Even in the case of a third pixel PXc composed of two segmented pixels, such as Figure 6 As shown, when rotated 90 degrees, the shape and arrangement of the third opening Hc remain substantially the same before and after the rotation, and there is no risk of change in the direction of the stretching force for the third pixel PXc.

[0103] In other words, because the third pixel PXc is composed of two segmented pixels located diagonally, the horizontal to vertical ratio can be made relatively small. Therefore, because the difference in the width of the mask opening in the direction parallel to the stretching force is small before and after the 90-degree rotation, the impact of stretching risk can be reduced or minimized.

[0104] On the other hand, Figure 7 and Figure 8 In the comparative example shown, because at least one of the three types of pixels—red, green, and blue—has an elongated shape in one direction, the deposition quality may deteriorate significantly during rotation due to the aforementioned stretching risk.

[0105] Figure 7 This is a top view showing the pixel arrangement based on the comparison example. (e.g.) Figure 7 As shown, the unit pixel includes a red pixel Pxr, a blue pixel Pxb, and a green pixel Pxg, with the red pixel Pxr and the green pixel Pxg forming the left column. Furthermore, the blue pixel Pxb is formed vertically in the column direction to form the right column. This is a conventional arrangement in traditional RGB drivers used to ensure aperture ratio while improving lifetime characteristics.

[0106] In this pixel arrangement, Figure 8 The image shows a blue mask M used to form the long blue pixel Pxb. (See image for details.) Figure 8 As shown, the blue mask M has a blue opening H corresponding to the shape of the blue pixel Pxb. Before rotation, as shown in the left figure, the blue opening H is subjected to a tensile force applied parallel to its length direction. In this case, the blue opening H is structurally stable to deformation because it is wide in the direction parallel to the tensile force.

[0107] On the other hand, after rotation, as shown in the right figure, the blue mask M receives a tensile force applied in the width direction parallel to the blue opening H. Since the blue opening H is formed longitudinally in a direction perpendicular to the tensile force direction, it deforms relatively easily along the width direction under tensile force. In other words, due to the large difference between the horizontal and vertical ratios, it may be difficult to ensure structural stability against changes in tensile force caused by rotation. To compensate for this, in Figure 8 In the structure, the width of the blue opening H in the length direction can be reduced. However, in this case, although the stability will be improved, there are limitations because it may be difficult to ensure the opening ratio.

[0108] On the other hand, as mentioned above, by dividing the pixels of any color in pixel PX into a diagonal arrangement, the difference between the horizontal and vertical ratios can be reduced or minimized for all pixels, thus ensuring stability against changes in stretching force caused by mask rotation.

[0109] Furthermore, since the arrangement includes segmented pixels, the degree of freedom for pixel shape and size transformation is greater than that of the comparative example. Therefore, the aperture ratio can be further improved by appropriately selecting the color or size of the subdivided pixels. For example, for light-emitting display devices with pixel densities of 265ppi and 254ppi, when used with... Figure 7 In contrasting examples of the same layout design, and in the use of... Figure 3 In the same layout design in Implementation 1, and in the version described later... Figure 9 In Embodiment 2, which uses the same layout design, the aperture ratio of each pixel is shown in Table 1 below. In this case, in Embodiment 1, the first pixel PXa is designed to be a red pixel, the second pixel PXb is a blue pixel, and the third pixel PXc is a green pixel (e.g., the green pixel is a dividing pixel), while in Embodiment 2, the first pixel PXa is designed to be a green pixel, the second pixel PXb is a blue pixel, and the third pixel PXc is a red pixel (e.g., the red pixel is a dividing pixel).

[0110] Table 1

[0111]

[0112] As shown in Table 1, for the same pixel density in the light-emitting display device according to the embodiments, compared with the light-emitting display device according to the comparative example, the aperture ratio of the first pixel PXa and the aperture ratio of the second pixel PXb are both increased, with the same aperture ratio of the segmented pixels (green pixels in Embodiment 1 and red pixels in Embodiment 2). Therefore, the brightness of pixels PXa, PXb, and PXc can be improved. Furthermore, if the aperture ratio is increased, even if the amount of light emitted per unit area of ​​pixels PXa, PXb, and PXc is reduced, pixels PXa, PXb, and PXc can still provide the same level of brightness, thus improving the lifetime of pixels PXa, PXb, and PXc. Meanwhile, the spacing between adjacent pixels PXa, PXb, and PXc corresponds to the process conditions (e.g., FMM alignment margin) corresponding to the emission layer of each of pixels PXa, PXb, and PXc deposited using a corresponding fine metal mask (e.g., the spacing between adjacent pixels PXa, PXb, and PXc is predetermined considering the process conditions). Therefore, according to the implementation method, not only can stability against changes in tensile force caused by mask rotation as described above be ensured, but productivity can also be improved by reducing the possibility of color mixing defects during the fine metal mask deposition process while increasing the aperture ratio of pixels PXa, PXb, and PXc. In the following, reference will be made to... Figures 9 to 15 Describe various implementation methods.

[0113] Figures 9 to 15 These are top views showing the arrangement of pixels in a light-emitting display device according to one or more embodiments.

[0114] refer to Figure 9Compared to the embodiments described above, there are differences in the shape and size of the first pixel PXa, the second pixel PXb, and the third pixel PXc. For example, all of the first pixel PXa, the second pixel PXb, and the third pixel PXc can be uniformly shaped into octagons (e.g., formed as approximately octagons), and for example, the shapes of the first pixel PXa, the second pixel PXb, and the first segmentation pixel PXc1 and the second segmentation pixel PXc2 of the third pixel PXc can be substantially similar. Furthermore, the first pixel PXa and the second pixel PXb can have the same size, and the third pixel PXc can be smaller. In this case, the first pixel PXa, the second pixel PXb, and the third pixel PXc can be designed to emit light of any color. For example, the third pixel PXc, including the first segmentation pixel PXc1 and the second segmentation pixel PXc2, can display any color among red, green, and blue. Thus, and as described in Embodiment 1 above, by arranging the first segmented pixel PXc1 and the second segmented pixel PXc2 to be spaced apart in the first diagonal direction dr1 of the pixel region PA, and by arranging the first pixel PXa and the second pixel PXb to be spaced apart in the second diagonal direction dr2, the aperture ratio and deposition stability can be improved, while ensuring stability against changes in tensile force caused by mask rotation.

[0115] refer to Figure 10Compared to the above embodiments, the difference in the shapes of the first pixel PXa, the second pixel PXb, and the third pixel PXc lies in that the shape of each pixel includes a curve. For example, the first pixel PXa and the second pixel PXb may have shapes including curves that bend toward the interior of the quadrilateral (i.e., toward their respective pixel centers), and the third pixel PXc may have an elliptical shape. Furthermore, the shapes of the first pixel PXa and the second pixel PXb may be substantially similar, and the shapes of the first segmentation pixel PXc1 and the second segmentation pixel PXc2 of the third pixel PXc may be substantially similar. In this case, the edges of the first pixel PXa facing each of the first segmentation pixels PXc1 and the second segmentation pixels PXc2, or the edges of the second pixel PXb facing each of the first segmentation pixels PXc1 and the second segmentation pixels PXc2, may be bent to be substantially complementary to the elliptical shapes of the first segmentation pixels PXc1 and / or the second segmentation pixels PXc2, or may be bent independently of the elliptical shapes of the first segmentation pixels PXc1 and / or the second segmentation pixels PXc2. When bent in complementary shapes, the corresponding distances between the first segmentation pixel PXc1 and the second segmentation pixel PXc2 and the first pixel PXa or the second pixel PXb can remain constant. However, it is not limited to what is described above, and the corresponding distances between the first segmentation pixel PXc1 and the second segmentation pixel PXc2 and the first pixel PXa or the second pixel PXb can vary depending on their position. Meanwhile, the first pixel PXa, the second pixel PXb, and the third pixel PXc can be designed to emit light of any color.

[0116] refer to Figure 11Compared to the above embodiments, there are differences in the shapes of the first pixel PXa, the second pixel PXb, and the third pixel PXc. For example, the first pixel PXa and the second pixel PXb may have shapes including curves that bend inward from their originally generally octagonal shapes (i.e., towards the center of the respective pixels), while the third pixel PXc may have a circular shape. Furthermore, for example, the shapes of the first pixel PXa and the second pixel PXb may be substantially similar, and the shapes of the first segmentation pixel PXc1 and the second segmentation pixel PXc2 of the third pixel PXc may be substantially similar. In this case, the edges of the first pixel PXa or the second pixel PXb facing each of the first segmentation pixel PXc1 and the second segmentation pixel PXc2 may be bent to be substantially complementary to the circular shape of the first segmentation pixel PXc1 or the second segmentation pixel PXc2, or these edges may be bent independently of the circular shape of the first segmentation pixel PXc1 or the second segmentation pixel PXc2. When bent in complementary shapes, the corresponding spacing between the first segmentation pixel PXc1 and the second segmentation pixel PXc2 and the first pixel PXa or the second pixel PXb can remain constant. However, the implementation is not limited to what has been described above, and the corresponding distances between the first segmentation pixel PXc1 and the second segmentation pixel PXc2 and the first pixel PXa or the second pixel PXb can vary depending on their positions. Meanwhile, the first pixel PXa, the second pixel PXb, and the third pixel PXc can be designed to emit light of any color.

[0117] refer to Figure 12 One or more embodiments differ from the embodiments described above in that the first pixel PXa, the second pixel PXb, and the third pixel PXc are not arranged parallel to the first line L1 of the pixel region PA (see [link to previous embodiment]). Figure 3 ) and second line L2 (see Figure 3 Furthermore, at least some pixels among the first pixel PXa, the second pixel PXb, and the third pixel PXc are not aligned with the center of the remaining pixels among the first pixel PXa, the second pixel PXb, and the third pixel PXc. And they are offset in the horizontal and / or vertical directions. For example, as... Figure 12 As shown in (a), throughout the entire plurality of pixel regions PA, the first segmentation pixel PXc1 and the second segmentation pixel PXc2 can be offset relative to the horizontal and vertical directions (e.g., offset to the left in the horizontal direction and offset upward in the vertical direction). Furthermore, as... Figure 12 As shown in (b), throughout the entire plurality of pixel regions PA, the first pixel PXa can be offset relative to both the horizontal and vertical directions (e.g., offset to the right in the horizontal direction and offset upwards in the vertical direction). Alternatively, as Figure 12As shown in (c), in only some pixel regions PA among multiple pixel regions PA (e.g., the pixel region PA located on the lower side in the figure), the first pixel PXa and the second segmentation pixel PXc2 can be offset relative to the horizontal direction (e.g., offset to the right). Furthermore, as... Figure 12 As shown in (d), in only some pixel regions PA among multiple pixel regions PA (e.g., the pixel region PA located on the lower side in the figure), the second pixel PXb and the first segmentation pixel PXc1 can be offset relative to the horizontal direction (e.g., offset to the left in the figure). However, the above configuration is merely an example and is not limited thereto, and the center of the pixel can be offset and positioned in various combinations.

[0118] refer to Figure 13 Compared to the above embodiment, the first pixel PXa and the second pixel PXb have the same shape, but the difference lies in the fact that the first segmented pixel PXc1 and the second segmented pixel PXc2 included in the third pixel PXc have different shapes. For example, the first pixel PXa and the second pixel PXb can be quadrilaterals (or quadrilaterals with chamfered corners), the first segmented pixel PXc1 can be elliptical, and the second segmented pixel PXc2 can be circular. Furthermore, the size of the first pixel PXa and the size of the second pixel PXb can be different from each other. However, the embodiment is not limited to this, and the shape and size of each pixel can be varied. Moreover, the first pixel PXa, the second pixel PXb, and the third pixel PXc can be designed to emit light of any color.

[0119] refer to Figure 14 Compared to the above embodiments, the difference lies in that the shapes of the first pixel PXa, the second pixel PXb, and the third pixel PXc are all identical, and only the dimensions of the first segmented pixel PXc1 and the second segmented pixel PXc2 differ. For example, the first pixel PXa, the second pixel PXb, and the third pixel PXc all have an octagonal shape, and the first pixel PXa and the second pixel PXb can have the same size. In this case, the size of the first segmented pixel PXc1 can be larger than the size of the second segmented pixel PXc2. However, the embodiments are not limited to this, and the shape and size of each pixel can be varied. Furthermore, the first pixel PXa, the second pixel PXb, and the third pixel PXc can be designed to emit light of any color. In addition, the shapes and sizes of the pixels listed above are not limited to a single pixel array and can be mixed and applied, or pixels of other shapes and sizes not shown can be applied.

[0120] refer to Figure 15Compared to the above embodiments, the difference lies in that the shapes of the first pixel PXa and the second pixel PXb are different, and the shapes of the first segmented pixel PXc1 and the second segmented pixel PXc2 included in the third pixel PXc are the same. For example, the first pixel PXa may have a quadrilateral (or a quadrilateral with chamfered corners) shape, the second pixel PXb may have a circular shape, and the first segmented pixel PXc1 and the second segmented pixel PXc2 may have an octagonal shape with a major axis, and for example, the shapes of the first segmented pixel PXc1 and the second segmented pixel PXc2 may be substantially similar. Furthermore, compared to... Figure 3 , Figure 9 , Figure 10 and Figure 11 Same, Figure 15 The dimensions of the first segmentation pixel PXc1 and the second segmentation pixel PXc2 can be substantially similar. However, the implementation is not limited to this, and the shape and size of each pixel can be varied. Furthermore, the first pixel PXa, the second pixel PXb, and the third pixel PXc can be designed to emit light of any color.
