[0043] This disclosure will now be described more fully below with reference to the accompanying drawings, in which various embodiments are illustrated. However, this disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art.

[0044] Because this disclosure allows for various modifications and numerous implementations, specific embodiments will be illustrated in the accompanying drawings and described in detail in the written description. Hereinafter, the effects and features of this disclosure, as well as methods for implementing them, will be described more fully with reference to the accompanying drawings, in which embodiments of this disclosure are illustrated. However, this disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein.

[0045] One or more embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Components that are identical or corresponding to each other are given the same reference numerals, and redundant explanations are omitted.

[0046] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, areas, layers, and / or segments, these elements, components, areas, layers, and / or segments should not be limited by these terms. These terms are used only to distinguish one element, component, area, layer, or segment from another. Therefore, “first element,” “first component,” “first area,” “first layer,” or “first segment” discussed below may be referred to as a second element, second component, second area, second layer, or second segment without departing from the teachings herein.

[0047] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the terms “a,” “an,” “the,” and “at least one,” as used herein, do not indicate a limitation of quantity and are intended to include both singular and plural forms. Therefore, a reference to “a” element in a claim followed by a reference to “the” element includes one element and multiple elements. For example, unless the context clearly indicates otherwise, “element” has the same meaning as “at least one element.” “At least one” is not to be construed as limited to “a” or “an.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0048] It will also be understood that the terms “comprise,” “comprising,” “include,” and / or “including” as used in this specification designate the presence of the stated features, areas, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, areas, integrals, steps, operations, elements, components, and / or groups thereof.

[0049] It will be understood that when a layer, zone, or component is referred to as being "on" another layer, zone, or component, it can be formed directly or indirectly on that other layer, zone, or component. That is, for example, an intermediary layer, zone, or component may exist therein. Conversely, when an element is referred to as being "directly" on another element, there is no intermediary element.

[0050] For ease of explanation, the dimensions of the elements in the accompanying drawings may be enlarged or reduced. For example, since the dimensions and thicknesses of the components in the drawings are arbitrarily illustrated for ease of explanation, the embodiments are not limited thereto.

[0051] When a particular implementation can be carried out in different ways, the specific process sequence may be performed differently than the order in which it is described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description.

[0052] It will also be understood that when a layer, zone, or component is referred to as a “connection” or “link” to another layer, zone, or component, it can be directly connected to or directly linked to the other layer, zone, or component, or an intermediary layer, zone, or component may exist. For example, when a layer, zone, or component is referred to as an “electrical connection” or “electrical link” to another layer, zone, or component, it can be directly electrically connected to or directly electrically linked to the other layer, zone, or component, or an intermediary layer, zone, or component may exist.

[0053] Taking into account the errors associated with measurements and a particular number of measurements (i.e., limitations of the measurement system), the terms "about" or "approximately" as used herein include the values ​​and mean within an acceptable range of deviation for a particular value as determined by one of ordinary skill in the art. For example, "about" can mean within one or more standard deviations, or within ±30%, 20%, 10%, or 5% of the value.

[0054] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have 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, unless expressly defined herein, terms (such as those defined in common dictionaries) shall be interpreted as having the same meaning as they have in the context of the relevant technology and this disclosure, and shall not be interpreted in an idealized or overly formal sense.

[0055] The embodiments are described herein with reference to illustrative cross-sectional views as idealized embodiments. Therefore, variations in the shape of the illustrated areas are contemplated due to factors such as manufacturing techniques and / or tolerances. Thus, the embodiments described herein should not be construed as being limited to a specific shape of the areas illustrated herein, but rather include deviations in shape caused, for example, by manufacturing processes. For instance, areas illustrated or described as flat may generally have rough and / or non-linear characteristics. Furthermore, acute angles in the illustrations may be rounded. Therefore, the areas illustrated in the figures are schematic in nature, and their shapes are not intended to depict the precise shape of the areas, nor are they intended to limit the scope of the claims.

[0071] refer to Figure 2AIn this embodiment, the display device 1 may be arranged on the instrument panel 1400. In this embodiment, the instrument panel 1400 can express driving information, etc., through the display device 1. That is, the instrument panel 1400 can be implemented digitally. The digital instrument panel 1400 can display vehicle information and driving information using images. In this embodiment, for example, the pointers of the tachometer and gauges, as well as various warning light icons, can be displayed using digital signals.

[0072] Light emitted from display device 1 can travel in a specific direction. In one embodiment, for example, light emitted from display device 1 can travel to the driver's seat. Light emitted from display device 1 may not travel towards the windshield 1200. In another embodiment, for example, light emitted from display device 1 can travel towards the windshield 1200 at a relatively small rate. In the case where light emitted from display device 1 travels towards the windshield 1200, the light emitted from display device 1 can be reflected by the windshield 1200 to reach the driver's seat. Therefore, the driver can recognize the image of display device 1 focused on the windshield 1200, and since the image on the windshield 1200 may distract the driver, it may cause safety problems while driving. According to an embodiment, light emitted from display device 1 arranged on the dashboard 1400 can travel in a specific direction. Therefore, the amount of light traveling towards the windshield 1200 can be effectively reduced.

[0073] refer to Figure 2B In one embodiment, the display device 1 may be arranged on the center console 1500. According to one embodiment, the display device 1 may display navigation information. According to another embodiment, the display device 1 may display information related to audio, video, or vehicle settings.

[0074] Light emitted from display device 1 can travel in a specific direction. In one embodiment, for example, light emitted from display device 1 can travel to the driver's seat. Light emitted from display device 1 can travel to the passenger seat. Light emitted from display device 1 may not travel towards the windshield 1200. In another embodiment, for example, light emitted from display device 1 can travel towards the windshield 1200 at a relatively small rate. In cases where light emitted from display device 1 travels towards the windshield 1200, the light emitted from display device 1 can be reflected by the windshield 1200 to reach the driver's seat. Therefore, the driver can recognize the image of display device 1 focused on the windshield 1200 and may not be able to recognize objects in the forward direction, and thus, the driver may be unsafe while driving because the image on the windshield 1200 may distract the driver. According to an embodiment, light emitted from display device 1 arranged on the center console 1500 can travel in a specific direction. Therefore, the amount of light traveling towards the windshield 1200 can be effectively reduced.

[0144] Figure 9 This is a schematic plan view of the second dashboard panel CL2 included in the display device 1 according to the embodiment. Figure 10A and Figure 10B This is a schematic plan view of a portion of the display device 1 according to an embodiment, and is Figure 9 An enlarged view of area B of display device 1.

[0145] In the implementation method, reference Figure 9 The second instrument panel CL2 may include at least one hole H defined by the second instrument panel CL2. For example... Figure 8 As shown, at least one hole H may include a first hole H1, a second hole H2, and a third hole H3. The first hole H1, the second hole H2, and the third hole H3 may be located in the central portion of the second instrument panel CL2 in the plan view, and may be arranged separately from each other.

[0146] According to the implementation method, the first hole H1 can be connected to the first instrument panel CL1 (see...). Figure 6The third display area DA3 (see) Figure 6 Correspondingly, the second hole H2 can be connected to the first instrument panel panel CL1 (see...). Figure 6 The second display area DA2 (see) Figure 6 Corresponding to, and the third hole H3 can be connected to the first instrument panel panel CL1 (see...). Figure 6 The fourth display area DA4 (see) Figure 6 Correspondingly, although the second instrument panel CL2 is arranged in relation to the first instrument panel CL1 (see...), Figure 6 Above, but the user can recognize the image implemented by the first instrument panel CL1 through at least one hole H of the second instrument panel CL2.

[0147] The second instrument panel CL2 may include a first display area DA1. The first display area DA1 may be the area within the planar region of the second instrument panel CL2, excluding at least one hole H. The first display area DA1 may surround at least one hole H. In other words, the first display area DA1 may surround the second display area DA2 (see...). Figure 6 ), third display area DA3 (see Figure 6 ) and the fourth display area DA4 (see Figure 6 Each of the regions in ).

[0148] Next, refer to Figure 10A Multiple sub-pixels P (see Figure 3A (This can be arranged in the first display area DA1.) Multiple sub-pixels P (see...) Figure 3A This may include a first sub-pixel P1', a second sub-pixel P2', and a third sub-pixel P3' that emit different colors of light. Each of the first sub-pixel P1', the second sub-pixel P2', and the third sub-pixel P3' may be provided as multiple. Figure 6 Like its first sub-pixel P1, the first sub-pixel P1' can emit red light, such as... Figure 6 Like the second sub-pixel P2, the second sub-pixel P2' can emit green light, and as... Figure 6 Like the third sub-pixel P3, the third sub-pixel P3' can emit blue light.

[0149] According to the implementation, a plurality of sub-pixels P (see [reference]) are arranged in the first display area DA1. Figure 3A The arrangement structure and orientation of the ) can be the same as those arranged in the second display area DA2 (see Figure 6 Multiple sub-pixels P in ) (see Figure 3A The layout and orientation of the components are the same. In other words, they are arranged on the first instrument panel CL1 (see...). Figure 6The arrangement structure and direction of the first sub-pixel P1, the second sub-pixel P2, and the third sub-pixel P3 in the instrument panel CL2 can be the same as the arrangement structure and direction of the first sub-pixel P1', the second sub-pixel P2', and the third sub-pixel P3' in the second instrument panel CL2.

[0150] In an implementation, for example, the first sub-pixel P1' and the second sub-pixel P2' may each have a rectangular shape, and the third sub-pixel P3' may have a square shape or a chamfered square shape. The first sub-pixel P1', the second sub-pixel P2', and the third sub-pixel P3' may be tilted relative to a first direction (e.g., the x-direction) or a second direction (e.g., the y-direction) to form a 45-degree angle.

[0151] The first pixel unit PU1' and the second pixel unit PU2' can be arranged in the first display area DA1. (See the first pixel unit PU1). Figure 7A ) and the second pixel unit PU2 (see Figure 7A Similarly, each of the first pixel unit PU1' and the second pixel unit PU2' can also be a subpixel component including a first subpixel P1', a second subpixel P2', and a third subpixel P3'. The first pixel unit PU1' can be the same as the first pixel unit PU1 (see...). Figure 7A ) has the same structure, and the second pixel unit PU2' can be the same as the second pixel unit PU2 (see Figure 7A The first pixel unit PU1' has the same structure. In an embodiment, for example, the first pixel unit PU1' may have a structure in which the longer side of the first sub-pixel P1' faces the longer side of the second sub-pixel P2' and another longer side of the second sub-pixel P2' faces one side of the third sub-pixel P3'. The second pixel unit PU2' may have a structure in which the longer side of the first sub-pixel P1' faces the longer side of the second sub-pixel P2' and the shorter side of the first sub-pixel P1' and the shorter side of the second sub-pixel P2' faces one side of the third sub-pixel P3'.

[0152] In this configuration, the first pixel unit PU1' and the second pixel unit PU2' can be repeatedly arranged in the first display area DA1. According to an embodiment, the first pixel unit PU1' can be arranged continuously in a second direction (e.g., the y-direction), and the second pixel unit PU2' can also be arranged continuously in a second direction (e.g., the y-direction). The first pixel unit PU1' and the second pixel unit PU2' can be arranged alternately in a first direction (e.g., the x-direction). In other words, a plurality of sub-pixels P arranged in the first display area DA1 (see...) Figure 3A The arrangement direction of the pixels can be the same as that of multiple sub-pixels P arranged in the second display area DA2 (see...). Figure 3A The arrangement directions are the same.

[0153] In the implementation method, reference Figure 10B The second instrument panel CL2 may include a plurality of second light shields 530'. Each of the plurality of second light shields 530' may extend substantially in a first direction (e.g., the x-direction). In an embodiment, each of the plurality of second light shields 530' may extend at an angle of about 5 degrees or less relative to the first direction (e.g., the x-direction). According to an embodiment, each of the plurality of second light shields 530' may extend at an angle relative to the first direction (e.g., the x-direction). Figure 7B Multiple first shading rays 530 extend with the same angle.

[0154] With this structure described above, although the display device 1 according to the embodiment has a different panel stacking structure, it can still achieve a display area DA (see above) throughout the entire display area. Figure 3A A uniform brightness is formed in the process.

[0155] In the implementation, even when arranged in the first instrument panel CL1 (see...) Figure 6 Multiple sub-pixels P in ) (see Figure 3A The arrangement structure of the multiple sub-pixels P arranged in the second instrument panel CL2 (see...) Figure 3A When the layout structures are the same, when arranged in the first instrument panel CL1 (see...) Figure 6 Multiple sub-pixels P in ) (see Figure 3A The arrangement direction of the pixels and the arrangement of the multiple sub-pixels P in the second instrument panel CL2 (see...) Figure 3A When the arrangement directions of the first display area DA1 and the second display area DA2 are the same, the first display area DA1 and the second display area DA2 (see Figure 6 They can also have different brightness levels. In an embodiment, for example, when arranged in the first instrument panel CL1 (see...), Figure 6 The first pixel unit PU1 on ) (see Figure 7A The first pixel unit PU1' (see) is arranged continuously in the second direction (e.g., the y-direction) and arranged on the second instrument panel panel CL2. Figure 7A When arranged continuously in a first direction (e.g., the x-direction), a first instrument panel CL1 can be generated (see...). Figure 6 The brightness difference between the first light shield 530 and the second instrument panel CL2. Specifically, this is due to multiple first light shields 530 (see...). Figure 7B ) and each of the multiple second shading rays 530' extends with a specific tilt, so even when only multiple sub-pixels P (see Figure 3A Brightness deviation and moire patterns can also occur when the arrangement direction of the elements is different.

[0156] Therefore, in the display device 1 according to the embodiment, the first instrument panel CL1 (see...) is arranged... Figure 6) and multiple sub-pixels P in the second instrument panel CL2 (see Figure 3A ) are formed with the same structure and the same arrangement direction, and multiple first shading light sources 530 (see Figure 7B The second light shield 530' and multiple second light shields are also formed at the same angle, and thus can effectively prevent brightness deviation and clouding problems.

[0157] Figure 11 This is a schematic cross-sectional view of a portion of the display device 1 according to an embodiment, and illustrates a section taken along line III-III'. Figure 10B A schematic cross-sectional view of the display device 1. Figure 11 This is a schematic cross-sectional view of a portion of the second instrument panel CL2, and Figure 11 Zhongyu Figure 4 and Figure 8 The same or similar reference numerals in the figures denote the same or similar elements, and therefore any repeated detailed descriptions thereof will be omitted.

[0158] refer to Figure 11 In one embodiment, the second instrument panel CL2 may include a second substrate 100', a second display layer 200', a second encapsulation member 300', a second anti-reflective layer 400', a second adhesive layer ADL', and a second optical path control layer 500'. The second display layer 200' may be disposed on the second substrate 100'. Figure 8 Similar to the first display layer 200, the second display layer 200' may include a pixel circuit layer 210 and a light-emitting element layer 220. The pixel circuit layer 210 and light-emitting element layer 220 included in the second display layer 200' may be similar to those included in the first display layer 200 (see [link to first display layer 200]). Figure 8 The pixel circuit layer 210 and the light-emitting element layer 220 in the first display layer 200 are substantially the same. However, the implementation is not limited to this, and the first display layer 200 (see [link to documentation]) is also included. Figure 8 The second display layer 200' may have different structures from each other.

[0159] The second encapsulation member 300' may be disposed on the second display layer 200'. The second encapsulation member 300' may cover the second display layer 200' to protect the second display layer 200' from external moisture, oxygen, etc. The second encapsulation member 300' may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. In an embodiment, for example, the second encapsulation member 300' may include a first inorganic encapsulation layer 330, an organic encapsulation layer 340, and a second inorganic encapsulation layer 350.

[0160] The first inorganic encapsulation layer 330 and the second inorganic encapsulation layer 350 may include materials such as silicon oxide (SiO2) and silicon nitride (SiN). x ), silicon oxynitride (SiO)x N y Aluminum oxide (Al2O3), titanium oxide (TiO2), tantalum oxide (Ta2O5), hafnium oxide (HfO2), or zinc oxide (ZnO) x Zinc oxide (ZnO) is at least one inorganic insulating material and can be formed by chemical vapor deposition (CVD) or the like. x The encapsulation layer 340 may include zinc oxide (ZnO) and / or zinc peroxide (ZnO2). The organic encapsulation layer 340 may include a polymer-based material. Examples of polymer-based materials may include silicone-based resins, acrylic-based resins (e.g., polymethyl methacrylate, polyacrylic acid, etc.), epoxy-based resins, polyimide, and polyethylene.

[0161] Because the first inorganic encapsulation layer 330 provides high step coverage, its upper surface may not be flat. However, the organic encapsulation layer 340 has a substantially flat upper surface, and therefore, the second inorganic encapsulation layer 350 on the organic encapsulation layer 340 may also have a substantially flat upper surface.

[0162] The second antireflective layer 400' may be disposed on the second encapsulation member 300', and the second optical path control layer 500' may be disposed on the second antireflective layer 400'. The second adhesive layer ADL' may be disposed between the second optical path control layer 500' and the second antireflective layer 400', and the second adhesive layer ADL' may be a transparent adhesive member, such as an OCA film.

[0163] The second optical path control layer 500' may include a second lower layer 510', a plurality of second light-shielding rays 530', and a second upper layer 520'. The second lower layer 510' may include a transparent resin and may include a plurality of grooves. The plurality of second light-shielding rays 530' may respectively fill the plurality of grooves and may be spaced apart from each other at a constant interval in a second direction (e.g., the y-direction). The plurality of second light-shielding rays 530' may each include a light-shielding material. The second upper layer 520' may be disposed on the second lower layer 510' and the plurality of second light-shielding rays 530'. The second upper layer 520' may include a polymer resin.

[0164] Figure 12A This is a layout diagram schematically showing the location of the first dashboard panel CL1 formed on the first substrate 100. Figure 12B This is a layout diagram schematically showing the location of the second dashboard panel CL2 formed on the second substrate 100'.

[0165] First, refer to Figure 12AMultiple first instrument panel CL1s can be arranged on the first substrate 100. Depending on the size of the first substrate 100, as many first instrument panel CL1s as possible can be arranged to accommodate the characteristics of the first substrate 100. According to an embodiment, the multiple first instrument panel CL1s can be arranged such that the longer side LS1 of the first instrument panel CL1 is parallel to the shorter side of the first substrate 100, and the shorter side SS1 of the first instrument panel CL1 is parallel to the longer side of the first substrate 100.

[0166] refer to Figure 12B Multiple second instrument panel CL2s can be arranged on the second substrate 100'. Depending on the size of the second substrate 100', as many second instrument panel CL2s as possible can be arranged to accommodate the characteristics of the second substrate 100'. According to an embodiment, the multiple second instrument panel CL2s can be arranged such that the longer side LS2 of the second instrument panel CL2 is parallel to the longer side of the second substrate 100' and the shorter side SS2 of the second instrument panel CL2 is parallel to the shorter side of the second substrate 100'.

[0167] That is, a plurality of first instrument panel panels CL1 can be arranged such that each of their long sides extends in a second direction (e.g., the y-direction), and a plurality of second instrument panel panels CL2 can be arranged such that each of their long sides extends in a first direction (e.g., the x-direction). When the arrangement direction of the first instrument panel panels CL1 as described above is different from the arrangement direction of the second instrument panel panels CL2, and a plurality of sub-pixels P (see...) Figure 3A When the first substrate 100 and the second substrate 100' are equally formed in the first display area DA1 (see...) Figure 9 Multiple sub-pixels P in ) (see Figure 3A The arrangement direction of the ) and the formation in the second display area DA2 (see Figure 6 Multiple sub-pixels P in ) (see Figure 3A The arrangement directions of the components are different. As mentioned above, it is desirable to form a component in the first display area DA1 (see...). Figure 9 ) and the second display area DA2 (see Figure 6 Multiple sub-pixels P in ) (see Figure 3A They not only have the same arrangement structure, but also the same arrangement direction to prevent brightness deviation.

[0168] Therefore, in the display device 1 according to the embodiment, a plurality of sub-pixels P formed in the first dashboard panel CL1 (see Figure 3A Rotate 90 degrees so that the first display area DA1 (see...) Figure 6 Multiple sub-pixels P in ) (see Figure 3A The arrangement direction of the second display area DA2 can be aligned with that of the second display area DA2 (see...). Figure 9 Multiple sub-pixels P in ) (see Figure 3A The arrangement direction of the pixels is the same. In this case, by improving the stretching or mounting method of the frame of the fine metal mask (FMM) in the device, multiple sub-pixels P can be formed in the first instrument panel CL1 in a 90-degree rotation direction (see...). Figure 3A In detail, when examining multiple sub-pixels P (see...), Figure 3A When distortion occurs, it is desirable not only to modify the software of the FMM stretcher, but also to consider a separate scanning method. Therefore, the display device 1 according to the embodiment, formed through such a modification process as described above, can eliminate brightness deviation and prevent moiré problems, thereby achieving a high-quality image.

[0169] Figure 13 This is a schematic plan view of display device 1 according to another embodiment. (See reference) Figure 13 Except for the features of the second display area DA2, the third display area DA3, and the fourth display area DA4, the other features are the same as those mentioned above. Figures 3A to 3C The described features are the same. Therefore, [the following will be omitted]. Figure 13 The reference above Figures 3A to 3C Any repeated detailed descriptions of components that are the same as or similar to the components described, and the differences between them will be described below.

[0170] refer to Figure 13 The implementation of display device 1 may include a display area DA and a non-display area NDA. Sub-pixels P may be arranged in the display area DA. The display area DA may include a first display area DA1, a second display area DA2, a third display area DA3, and a fourth display area DA4. The second display area DA2, the third display area DA3, and the fourth display area DA4 may be arranged inside the first display area DA1 and may be completely surrounded by the first display area DA1.

[0171] According to the implementation method, such as Figure 13 As shown in the diagram, in the plan view, the second display area DA2, the third display area DA3, and the fourth display area DA4 may have a circular shape. However, the implementation is not limited to this, and the second display area DA2, the third display area DA3, and the fourth display area DA4 may have an elliptical shape. In other words, in the plan view, the second instrument panel CL2 (see...) Figure 9 At least one hole H in ) (see Figure 9 It can have a circular shape.

[0172] Therefore, according to another embodiment, a vehicle can display images in driving mode on a second display area DA2, a third display area DA3, and a fourth display area DA4, each having a circular shape. However, compared with... Figure 3C Similarly, according to another embodiment, the vehicle can also display images on all of the first display area DA1, the second display area DA2, the third display area DA3, and the fourth display area DA4 in non-driving mode. Since the second display area DA2, the third display area DA3, and the fourth display area DA4 are formed into various shapes as described above, the vehicle according to the other embodiment can be designed in various ways to enhance its aesthetics.

[0173] Figure 14A and Figure 14B These are schematic plan views of portions of display device 1 according to another embodiment. (See reference) Figure 14A and Figure 14B In addition to multiple sub-pixels P (see Figure 3A Other features besides the arrangement direction are the same as those mentioned above. Figures 6 to 11 The described features are the same. Therefore, [the following will be omitted]. Figure 14A and Figure 14B The reference above Figures 6 to 11 Any repeated detailed descriptions of components that are the same as or similar to the components described, and the differences between them will be described below.

[0174] In the implementation method, reference Figure 14A Multiple sub-pixels P (see Figure 3A This can be arranged in the first instrument panel CL1. Multiple sub-pixels P (see...) Figure 3A It may include a first sub-pixel P1 that emits red light, a second sub-pixel P2 that emits green light, and a third sub-pixel P3 that emits blue light. Each of the first sub-pixel P1, the second sub-pixel P2, and the third sub-pixel P3 may be provided as multiple.

[0175] The first pixel unit PU1 and the second pixel unit PU2 may be arranged in the first instrument panel CL1. The first pixel unit PU1 and the second pixel unit PU2 may be arranged adjacent to each other. Each of the first pixel unit PU1 and the second pixel unit PU2 may be a sub-pixel component including a first sub-pixel P1, a second sub-pixel P2 and a third sub-pixel P3.

In the first pixel unit PU1, the third sub-pixel P3, the second sub-pixel P2, and the first sub-pixel P1 may be arranged sequentially in a fourth direction (e.g., the ax2 direction). In other words, the longer side of the first sub-pixel P1 and the longer side of the second sub-pixel P2 may be parallel to a side of the third sub-pixel P3 extending in a third direction (e.g., the ax1 direction).

[0177] According to an embodiment, the second pixel unit PU2 may have a structure in which the longer side of the first sub-pixel P1 faces the longer side of the second sub-pixel P2, and the shorter side of the first sub-pixel P1 and the shorter side of the second sub-pixel P2 face a side of the third sub-pixel P3. In other words, the shorter side of the first sub-pixel P1 and the shorter side of the second sub-pixel P2 may be parallel to a side of the third sub-pixel P3 extending in a third direction (e.g., the ax1 direction).

[0178] In this embodiment, the first pixel unit PU1 and the second pixel unit PU2 are repeatedly arranged in the first instrument panel CL1. According to the embodiment, the first pixel unit PU1 may be arranged continuously in a first direction (e.g., the x-direction), and the second pixel unit PU2 may also be arranged continuously in the first direction (e.g., the x-direction). The first pixel unit PU1 and the second pixel unit PU2 may be arranged alternately in a second direction (e.g., the y-direction).

[0179] In the implementation method, reference Figure 14B Multiple sub-pixels P (see Figure 3A This can be arranged in the second instrument panel CL2. Multiple sub-pixels P (see...) Figure 3A It may include a first sub-pixel P1' that emits red light, a second sub-pixel P2' that emits green light, and a third sub-pixel P3' that emits blue light. Each of the first sub-pixel P1', the second sub-pixel P2', and the third sub-pixel P3' may be provided as multiple.

[0180] According to the implementation, the first display area DA1 arranged in the second instrument panel panel CL2 (see...) Figure 9 Multiple sub-pixels P in ) (see Figure 3A The arrangement structure and orientation of the second display area DA2 (see) on the first instrument panel CL1 can be the same as those of the second display area DA2 (see) on the first instrument panel CL1. Figure 6 Multiple sub-pixels P in ) (see Figure 3A The layout structure and layout direction are the same.

[0181] The first pixel unit PU1' and the second pixel unit PU2' can be arranged in the second instrument panel CL2. (See the first pixel unit PU1). Figure 14A ) and the second pixel unit PU2 (see Figure 14A Similarly, the first pixel unit PU1' and the second pixel unit PU2' can each be a sub-pixel component including a first sub-pixel P1', a second sub-pixel P2', and a third sub-pixel P3'. The first pixel unit PU1' can be the same as the first pixel unit PU1 (see...). Figure 14A ) has the same structure, and the second pixel unit PU2' can be the same as the second pixel unit PU2 (see Figure 14AThe first pixel unit PU1' has the same structure. In an embodiment, for example, the first pixel unit PU1' may have a structure in which the longer side of the first sub-pixel P1' faces the longer side of the second sub-pixel P2' and another longer side of the second sub-pixel P2' faces one side of the third sub-pixel P3'. The second pixel unit PU2' may have a structure in which the longer side of the first sub-pixel P1' faces the longer side of the second sub-pixel P2' and the shorter side of the first sub-pixel P1' and the shorter side of the second sub-pixel P2' faces one side of the third sub-pixel P3'.

The first pixel unit PU1' and the second pixel unit PU2' can be arranged alternately in a second direction (e.g., the y-direction). In other words, multiple sub-pixels P arranged in the display area DA of the first instrument panel panel CL1 (see...) Figure 3A The arrangement direction of the pixels can be aligned with that of multiple sub-pixels P arranged in the display area DA of the second instrument panel CL2 (see...). Figure 3A The arrangement directions are the same.

[0183] In the implementation, as described above, a plurality of sub-pixels P (see above) are arranged in the first dashboard panel CL1. Figure 3A The arrangement structure and orientation of the pixels are similar to those of the multiple sub-pixels P arranged in the second instrument panel CL2 (see [reference]). Figure 3A The arrangement structure and orientation of the elements are the same to effectively prevent brightness deviation. That is, even when... Figure 14A and Figure 14B When the first pixel unit PU1, the first pixel unit PU1', the second pixel unit PU2, and the second pixel unit PU2' shown are arranged individually and sequentially in the first direction (e.g., the x-direction), the brightness can remain uniform as long as the arrangement directions between the display areas DA are the same. Therefore, the display device 1 according to the embodiment can also eliminate brightness deviation and prevent moiré problems, thereby achieving a high-quality image.

[0184] The display device according to the embodiments described above can achieve high-quality images by ensuring uniform brightness and effectively preventing the appearance of moiré patterns. These effects are merely examples, and the scope of this disclosure is not limited thereto.
