Description

Technical Field

[0001] This invention relates to a display device and an audio system including the same. Background Technology

[0002] With the development of multimedia, the importance of display devices is increasing. In response, various types of display devices are being used, such as Organic Light Emitting Display (OLED) and Liquid Crystal Display (LCD). Display devices, as devices for displaying images, include display panels such as light-emitting display panels or liquid crystal display panels.

[0003] In recent years, in addition to display devices that display high-quality images, there has been an increasing demand for display devices that can provide immersive sound in conjunction with a separate audio system. However, when the audio system is positioned on the back of the display panel, its sound may be blocked by the panel. Therefore, even with a high-quality audio system, it is difficult to provide a truly immersive sound experience when the audio system is positioned on the back of the display panel. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a display device that includes a hole for sound to pass through, so that it can provide a sense of presence even when the audio device is disposed on the back of the display panel.

[0005] Another problem to be solved by the present invention is to provide an audio system that includes a hole for sound to pass through through a display panel, so as to provide a sense of presence even when the audio device is disposed on the back of the display panel.

[0006] The subject matter of this invention is not limited to the subject matter mentioned above, and those skilled in the art should be able to clearly understand other technical subject matter not mentioned from the following description.

[0007] An embodiment of a display device for solving the aforementioned problem includes: a display panel including a plurality of first holes arranged in a first direction and a second direction intersecting the first direction; and a first panel lower part disposed on one side of the display panel, including a plurality of second holes arranged in the first direction and the second direction. When the maximum length of each of the first holes in the first direction is defined as 'a' and the minimum distance between adjacent first holes in the first direction is defined as 'c', the maximum length of each of the second holes in the first direction satisfies e×(a+c). Here, e is a positive integer.

[0008] Another embodiment of the display device for solving the aforementioned problem includes: a first display panel including a plurality of first holes arranged in a first direction and a second direction intersecting the first direction; and a lower portion of the first panel disposed on one side of the display panel and including a plurality of second holes arranged in the first direction and the second direction. Any one of the plurality of second holes overlaps with at least one of the plurality of first holes.

[0009] An embodiment of an audio system for addressing the aforementioned other issues includes: a display panel including a plurality of first holes arranged in a first direction and a second direction intersecting the first direction; a lower part of a first panel disposed on one side of the display panel and including a plurality of second holes arranged in the first direction and the second direction; and a sound output device disposed on one side of the lower part of the first panel and outputting sound. When the maximum length of each of the first holes in the first direction is defined as 'a' and the minimum distance between adjacent first holes in the first direction is defined as 'c', the maximum length of each of the second holes in the first direction satisfies e×(a+c), where e is a positive integer.

[0010] Specific details of other embodiments are included in the detailed description and accompanying drawings.

[0011] (Invention Effects)

[0012] According to the embodiment of the display device and the audio system including it, since each of the second holes of the lower panel member overlaps with at least one first hole in the thickness direction of the display panel, the first sound output from the first sound generating device and the second sound output from the second sound generating device can be output towards the front surface of the display device through the second holes of the lower panel member and the first hole of the display panel. That is, even if the first sound generating device and the second sound generating device are located on the back of the display device, the first sound output from the first sound generating device and the second sound output from the second sound generating device will not be blocked by the display panel and the lower panel member. Therefore, even when the first sound generating device and the second sound generating device are arranged on the back of the display panel, a sound with a sense of presence can be provided.

[0013] The effects described in the embodiments are not limited to those illustrated above, and more effects are included in this specification. Attached Figure Description

[0056] The advantages, features, and methods of achieving these advantages and features of the invention will become apparent from the various embodiments described in detail below with reference to the accompanying drawings. However, the invention is not limited to the embodiments disclosed below and may be implemented in different forms. These embodiments are provided merely to complete the disclosure of the invention and to fully inform those skilled in the art of the scope of the invention; the invention should be defined only by the scope of the claims.

[0057] The presence of elements or layers on other elements or layers includes not only cases where they are directly on other elements, but also cases where other layers or elements are sandwiched between them. Throughout this specification, the same reference numerals refer to the same constituent element. The shapes, sizes, ratios, angles, numbers, etc., disclosed in the accompanying drawings used to illustrate the various embodiments are illustrative, and the invention is not limited to the illustrated cases.

[0058] Although terms such as "first" and "second" are used to describe the constituent elements, the constituent elements are certainly not limited to these terms. These terms are used only for the purpose of distinguishing one constituent element from the others. Therefore, within the technical concept of this invention, the "first constituent element" mentioned below can also be a "second constituent element."

[0059] Various features of the embodiments of the present invention can be combined or integrated with each other in part or in whole. Various linkages and drives are technically possible, and the embodiments can be implemented independently of each other or implemented together in a related relationship.

[0060] The specific embodiments are described below with reference to the accompanying drawings.

[0061] Figure 1a This is an exploded perspective view showing an embodiment of an audio system including a display device. Figure 1b This is a schematic side view of an audio system including a display device according to an embodiment.

[0062] Reference Figure 1a and Figure 1b One embodiment of the audio system includes a display device 10, a first sound generating device 20, and a second sound generating device 30.

[0063] One embodiment of the display device 10 is a device for displaying dynamic or static images. It can be used not only as a display screen for portable electronic devices such as mobile phones, smartphones, tablet PCs, smartwatches, watch phones, mobile communication terminals, electronic manuals, e-books, PMPs (portable multimedia players), navigators, and UMPCs (Ultra Mobile PCs), but also as a display screen for various products such as televisions, laptops, monitors, billboards, and Internet of Things (IoT) devices.

[0064] In this specification, the display device 10 of one embodiment is exemplified as an inorganic light-emitting display device that includes inorganic semiconductor devices as light-emitting elements, but is not limited thereto.

[0065] The display device 10 includes a display panel 100, a display driving circuit 200, a circuit board 300, and a lower part of the first panel 400.

[0066] The display panel 100 can be formed as a rectangular plane having a long side in a first direction (X-axis direction) and a short side in a second direction (Y-axis direction) intersecting the first direction (X-axis direction). The corner where the long side in the first direction (X-axis direction) and the short side in the second direction (Y-axis direction) meet can be rounded to have a predetermined curvature or formed as a right angle. The planar shape of the display panel 100 is not limited to a quadrilateral, and can be formed as other polygons, circles, or ellipses. Although the display panel 100 can be formed as flat, it is not limited to this. For example, the display panel 100 may include a curved surface with a certain curvature or a varying curvature. Alternatively, the display panel 100 can be formed as flexible so that it can be bent, distorted, folded, rolled, or folded.

[0067] The display panel 100 may include a display area DA for displaying images and a non-display area NDA disposed around the periphery of the display area DA. The display area DA may occupy most of the area of ​​the display panel 100. The display area DA may be configured in the center of the display panel 100. Pixels may be configured in the display area DA for displaying images.

[0068] Furthermore, a first hole H1 can be configured in the display area DA. Each first hole H1 can be a hole that penetrates the display panel 100. The first holes H1 can be arranged in a first direction (X-axis direction) and a second direction (Y-axis direction). That is, the first holes H1 can be arranged in a matrix form.

[0069] The non-display area NDA can be configured to be adjacent to the display area DA. The non-display area NDA can be an outer region of the display area DA. The non-display area NDA can be configured to surround the display area DA. The non-display area NDA can be an edge region of the display panel 100.

[0070] For connection with circuit board 300, display pads can be configured in the non-display area NDA. The display pads can be configured at one edge of the display panel 100. For example, the display pads can be configured at the upper edge of the display panel 100.

[0071] Multiple circuit boards 300 can be configured on display pads located at one edge of the display panel 100. Figure 1a Eight circuit boards 300 are illustrated, but the number of circuit boards 300 is not limited to this in this specification.

[0072] The circuit board 300 can be attached to the display pads using low-resistance, high-reliability components such as anisotropic conductive film or self-assembly anisotropic conductive paste (SAP). Thus, the circuit board 300 can be electrically connected to the signal wiring of the display panel 100. The display panel 100 can receive various signal inputs through the circuit board 300. The circuit board 300 can be a flexible film such as a flexible printed circuit board, a printed circuit board, or a chip-on-film (COF) substrate.

[0073] The display driver circuit 200 can generate various signals such as data voltage and / or power supply voltage. The display driver circuit 200 can supply various signals to the display panel 100 via the circuit board 300.

[0074] Each display driving circuit 200 can be formed by an integrated circuit (IC) and attached to the circuit board 300. Alternatively, the display driving circuit 200 can be attached to the display panel 100 by COG (chip on glass), COP (chip on plastic), or ultrasonic bonding.

[0075] The lower first panel component 400 may be disposed on one side of the display panel 100. The lower first panel component 400 may be disposed on the opposite side of the display surface of the display panel 100 where an image is displayed. For example, if an image is displayed on the front surface of the display panel 100, the lower first panel component 400 may be disposed on the back surface of the display panel 100.

[0076] The lower part of the first panel 400 may include second holes H2. Each second hole H2 may be a hole that passes through the lower part of the first panel 400. The second holes H2 may be arranged in a first direction (X-axis direction) and a second direction (Y-axis direction). That is, the second holes H2 may be arranged in a matrix. Each second hole H2 may overlap with at least one first hole H1 in a third direction (Z-axis direction). On the other hand, for ease of explanation, a first hole region HA1 is defined in the display panel 100, and a second hole region HA2 is defined in the lower part of the first panel 400, which will be explained in detail below. Figure 2 Detailed explanation will follow.

[0077] The lower part of the first panel 400 may include at least one of a light-absorbing component for absorbing light incident from the outside, a buffer component for absorbing impacts from the outside, and a heat dissipation component for effectively releasing heat from the display panel 100.

[0078] The light-absorbing component blocks light transmission to prevent the structure (e.g., circuit board 300) located below the light-absorbing component from being seen from the upper part of the display panel 100. The light-absorbing component may include a light-absorbing material such as black pigment or black dye.

[0079] The cushioning component can absorb external impacts to prevent damage to the display panel 100. For example, the cushioning component can be formed from a polymer resin such as polyurethane, polycarbonate, polypropylene, or polyethylene, or it can be formed from an elastic material such as rubber, a sponge made by foaming urethane or acrylic materials.

[0080] The heat dissipation component serves to dissipate heat generated by the display panel 100. The heat dissipation component may include thin films of metals with excellent thermal conductivity, such as copper, nickel, ferrite, or silver. Alternatively, the heat dissipation component may include graphite or carbon nanotubes, and in this case, it may shield electromagnetic waves.

[0081] Alternatively, the lower part of the first panel 400 may be a lower base. The lower part of the first panel 400 may form the appearance of the back of the display device 10. For example, the lower part of the first panel 400 may be metal or tempered glass.

[0082] Combining Figure 26a and Figure 26b Let’s describe the lower part of the first panel, component 400, in detail.

[0083] The first sound generating device 20 and the second sound generating device 30 can each output sound. The first sound generating device 20 and the second sound generating device 30 can output the same sound or output different sounds. The first sound generating device 20 and the second sound generating device 30 can each be a loudspeaker.

[0084] The first sound generating device 20 and the second sound generating device 30 may be disposed on one side of the lower part of the first panel 400. For example, when the display panel 100 is disposed on the front surface of the lower part of the first panel 400, the first sound generating device 20 and the second sound generating device 30 may be disposed on the back side of the lower part of the first panel 400. The first sound generating device 20 and the second sound generating device 30 may output sound toward the back side of the lower part of the first panel 400.

[0085] The first sound generating device 20 may be configured adjacent to the right side of the display device 10, and the second sound generating device 30 may be configured adjacent to the left side of the display device 10. In embodiments of the present invention, the configuration positions of the first sound generating device 20 and the second sound generating device 30 are not limited thereto.

[0086] like Figure 1a and Figure 1bAs shown, since each of the second holes H2 overlaps with at least one first hole H1 in the third direction (Z-axis direction), the first sound SOD1 output from the first sound generating device 20 and the second sound SOD2 output from the second sound generating device 30 can be output towards the front surface of the display device 10 through the second hole H2 of the lower part of the first panel 400 and the first hole H1 of the display panel 100. That is, the first hole H1 and the second hole H2 can be holes that allow sound to pass through. Therefore, even if the first sound generating device 20 and the second sound generating device 30 are located on the back of the display device 10, the first sound SOD1 output from the first sound generating device 20 and the second sound SOD2 output from the second sound generating device 30 can be unblocked by the display panel 100 and the lower part of the first panel 400. Therefore, even when the first sound generating device 20 and the second sound generating device 30 are arranged on the back of the display panel 100, a sound with a sense of presence can be provided.

[0087] On the other hand, in order for each second hole H2 to overlap with at least one first hole H1 in the third direction (Z-axis direction), the first panel lower component 400 should be attached to one side of the display panel 100 after the display panel 100 is aligned with the first panel lower component 400. In this case, a separate device is required to attach the first panel lower component 400 to one side of the display panel 100, which may not only increase manufacturing costs but also increase manufacturing time. Therefore, it is necessary to design the first holes H1 and second holes H2 such that even if the display panel 100 and the first panel lower component 400 are not aligned when attached, each second hole H2 overlaps with at least one first hole H1 in the third direction (Z-axis direction). Figures 2 to 6 Please provide a detailed explanation.

[0088] Figure 2 This is a layout diagram illustrating an example of a first hole in a display panel and a second hole in a lower component of the first panel, according to an embodiment. Figure 3 It is shown Figure 2 An example diagram of the overlapping area of ​​the first hole in the display panel and the second hole in the lower part of the first panel component.

[0089] For ease of explanation, Figure 2 Only shown Figure 1a The first hole H1 in the first hole region HA1. For ease of explanation, in Figure 3 Only shown Figure 1a The second pore H2 in the second pore region HA2.

[0090] Reference Figure 2 and Figure 3 The first hole H1 and the second hole H2 can each have a polygonal planar shape. Figure 2 and Figure 3 The example illustrates a case where the first hole H1 and the second hole H2 each have a rectangular planar shape, but this is not a limitation. The planar shapes of the first holes H1 and the second holes H2 may differ. For example, each first hole H1 may have a polygonal planar shape other than a quadrilateral, and each second hole H2 may have a quadrilateral planar shape. Alternatively, each first hole H1 may have a rectangular planar shape, and each second hole H2 may have a rhomboid planar shape.

[0091] The size of each second hole H2 can be larger than the size of each first hole H1. That is, the area of ​​each second hole H2 can be larger than the area of ​​each first hole H1. For example, the area of ​​each first hole H1 can be several μm. 2 Up to several hundred μm 2 .

[0092] The maximum length of each first hole H1 in the first direction (X-axis direction) can be defined as "a", and the minimum distance between adjacent first holes H1 in the first direction (X-axis direction) can be defined as "c". Furthermore, the maximum length of each first hole H1 in the second direction (Y-axis direction) can be defined as "b", and the minimum distance between adjacent first holes H1 in the second direction (Y-axis direction) can be defined as "d".

[0093] When the maximum length 'a' of each first hole H1 in the first direction (X-axis direction) is greater than the minimum distance 'c' between adjacent first holes H1 along the first direction (X-axis direction), the area of ​​pixels configured in the display area DA may be significantly reduced due to the first holes H1. Therefore, the maximum length 'a' of each first hole H1 in the first direction (X-axis direction) can be less than the minimum distance 'c' between adjacent first holes H1 along the first direction (X-axis direction).

[0094] Furthermore, when the maximum length b of each first hole H1 in the second direction (Y-axis direction) is greater than the minimum distance d between adjacent first holes H1 along the second direction (Y-axis direction), the area of ​​pixels configured in the display area DA may be significantly reduced due to the first holes H1. Therefore, the maximum length b of each first hole H1 in the second direction (Y-axis direction) can be less than the minimum distance d between adjacent first holes H1 along the second direction (Y-axis direction).

[0095] The maximum length 'a' of each first hole H1 in the first direction (X-axis direction) may differ from the maximum length 'b' of each first hole H1 in the second direction (Y-axis direction). However, the embodiments described herein are not limited thereto, and the maximum length 'a' of each first hole H1 in the first direction (X-axis direction) may be substantially equivalent to the maximum length 'b' of each first hole H1 in the second direction (Y-axis direction).

[0096] The minimum distance c between adjacent first holes H1 in the first direction (X-axis direction) may be different from the minimum distance d between adjacent first holes H1 in the second direction (Y-axis direction). However, the embodiments of this specification are not limited thereto, and the minimum distance c between adjacent first holes H1 in the first direction (X-axis direction) may be substantially equivalent to the minimum distance d between adjacent first holes H1 in the second direction (Y-axis direction).

[0097] Furthermore, the maximum length of each second hole H2 in the first direction (X-axis direction) and the minimum distance between adjacent second holes H2 in the first direction (X-axis direction) can be defined as e×(a+c). Similarly, the maximum length of each second hole H2 in the second direction (Y-axis direction) and the minimum distance between adjacent second holes H2 in the second direction (Y-axis direction) can be defined as f×(b+d). Here, e and f can be positive integers. Figure 2 and Figure 3 The example shows the case where e and f are both 1.

[0098] That is, the length (a+c) of each second hole H2 in the first direction (X-axis direction) and the minimum distance (a+c) between adjacent second holes H2 in the first direction (X-axis direction) can be defined as the sum of the maximum length a of each first hole H1 in the first direction (X-axis direction) and the minimum distance c between adjacent first holes H1 in the first direction (X-axis direction). Furthermore, the length (b+d) of each second hole H2 in the second direction (Y-axis direction) and the minimum distance (b+d) between adjacent first holes H1 in the second direction (Y-axis direction) can be defined as the sum of the maximum length b of each second hole H2 in the second direction (Y-axis direction) and the minimum distance d between adjacent first holes H1 in the second direction (Y-axis direction).

[0099] In this case, even if the display panel 100 including the first hole H1 and the lower part of the first panel 400 including the second hole H2 are not aligned, each of the second holes H2 can overlap with at least one first hole H1 in the third direction (Z-axis direction).

[0100] exist Figure 3The diagram illustrates the case where each second hole H2 overlaps with a first hole H1. For example, each second hole H2 may overlap with any one of the first holes H1 in a 2×2 row and column layout, but not with the remaining three first holes H1. Each second hole H2 may completely overlap with any one of the first holes H1.

[0101] like Figure 2 and Figure 3 As shown, each second hole H2 can overlap with at least one first hole H1 in the third direction (Z-axis direction). Therefore, even if the first sound generating device 20 and the second sound generating device 30 are located on the back of the display device 10, the first sound SOD1 output from the first sound generating device 20 and the second sound SOD2 output from the second sound generating device 30 can be output towards the front surface of the display device 10 without being blocked by the display panel 100 and the lower part of the first panel 400, and can be output sequentially through the second hole H2 of the lower part of the first panel 400 and the first hole H1 of the display panel 100. Therefore, even when the first sound generating device 20 and the second sound generating device 30 are arranged on the back of the display panel 100, a sound with a sense of presence can be provided.

[0102] Figure 4 It is shown Figure 2 Another example of the overlapping area of ​​the first hole of the display panel and the second hole of the lower part of the first panel.

Figure 22 It is shown Figure 21 An example of the overlap between the first hole of the display panel and the second hole of the lower part of the first panel component.

[0134] Figure 21 and Figure 22 The embodiments, except for those where the first hole H1 and the second hole H2 have elliptical planar shapes, are combined with Figure 2 and Figure 3 The situations described are essentially the same, therefore the details are omitted. Figure 21 and Figure 22 Description of the embodiments.

[0135] The elliptical planar shape of each first hole H1 may differ from that of each second hole H2. For example, the length of the major axis of each first hole H1 may differ from the length of the major axis of each second hole H2, or the length of the minor axis of each first hole H1 may differ from the length of the minor axis of each second hole H2.

[0136] In addition, although Figure 22 The illustration shows a case where each second hole H2 overlaps with one first hole H1, but the embodiments described herein are not limited to this. That is, each second hole H2 may overlap with at least two first holes H1.

[0137] exist Figures 2 to 22 The illustrations show cases where each first hole H1 has a polygonal, circular, or elliptical planar shape and each second hole H2 has a polygonal, circular, or elliptical planar shape. However, it should be noted that the planar shapes of the first hole H1 and the second hole H2 may have other shapes within the scope that can be modified by those skilled in the art.

[0138] Figure 23a and Figure 23b This is a layout diagram showing a first hole in a display panel and a second hole in a lower component of the first panel according to an embodiment. Figure 24 It is shown Figure 23a and Figure 23b An example of the overlap between the first hole of the display panel and the second hole of the lower part of the first panel component.

[0139] Figure 23a , Figure 23b and Figure 24 Implementation examples and Figure 2 and Figure 3 The difference in the embodiment is that the maximum length of each second hole H2 in the first direction (X-axis direction) and the minimum distance between adjacent second holes H2 in the first direction (X-axis direction) are "3×(a+c)", and the maximum length of each second hole H2 in the second direction (Y-axis direction) and the minimum distance between adjacent second holes H2 in the second direction (Y-axis direction) are "2×(b+d)". Figure 23a , Figure 23b and Figure 24 The main explanation and Figure 2 and Figure 3 Differences between the embodiments.

[0140] Reference Figure 23a , Figure 23b and Figure 24The maximum length 3×(a+c) of each second hole H2 in the first direction (X-axis direction) and the minimum distance 3×(a+c) between adjacent second holes H2 in the first direction (X-axis direction) can be three times the sum of the maximum length a of each first hole H1 in the first direction (X-axis direction) and the minimum distance c between adjacent first holes H1 in the first direction (X-axis direction). Furthermore, the maximum length 2×(b+d) of each second hole H2 in the second direction (Y-axis direction) and the minimum distance 2×(b+d) between adjacent second holes H2 in the second direction (Y-axis direction) can be twice the sum of the maximum length b of each first hole H1 in the second direction (Y-axis direction) and the minimum distance d between adjacent first holes H1 in the second direction (Y-axis direction). In this case, even if the display panel 100 including the first holes H1 and the lower part of the first panel 400 including the second holes H2 are not aligned, each second hole H2 can overlap with at least six first holes H1 in the third direction (Z-axis direction).

[0141] For example, such as Figure 24 As shown, each second hole H2 can overlap with six of the first holes H1 in a 6×4 row and column configuration, but not with the remaining first holes H1. Each second hole H2 can completely overlap with the six first holes H1.

[0142] Alternatively, each second hole H2 may overlap with nine of the first holes H1 in a 6×4 row and column configuration, but not with the remaining first holes H1. Each second hole H2 may completely overlap with three of the nine first holes H1. Furthermore, each second hole H2 may partially overlap with six of the nine first holes H1.

[0143] Alternatively, each second hole H2 may overlap with twelve of the twelve first holes H1 in a 6×4 row and column configuration, but not with the remaining first holes H1. Each second hole H2 may completely overlap with six of the twelve first holes H1. Furthermore, each second hole H2 may partially overlap with six of the twelve first holes H1.

[0144] Figure 25 This is a layout diagram illustrating the pixels and first hole of a display panel according to one embodiment. Figure 25 It shows Figure 1a The display panel 100 shown has a display area DA with pixels PX and a first hole H1.

[0145] Reference Figure 25 Each pixel PX can be arranged in a matrix form along the first direction (X-axis direction) and the second direction (Y-axis direction).

[0146] Each first hole H1 can be arranged in a matrix shape in the first direction (X-axis direction) and the second direction (Y-axis direction). That is, each first hole H1 can be arranged in a matrix shape.

[0147] The first aperture H1 may not overlap with pixel PX in the first direction (X-axis direction). The first aperture H1 may not overlap with pixel PX in the second direction (Y-axis direction). The first aperture H1 may be disposed between adjacent pixels PX in the diagonal directions DRA / DRB. For example, the first aperture H1 may be disposed between adjacent pixels PX in the DRA direction, which is inclined at approximately 43 degrees from the first direction (X-axis direction). Furthermore, the first aperture H1 may be disposed between adjacent pixels PX in the DRB direction, which is between the reverse direction of the first direction (X-axis direction) and the second direction (Y-axis direction).

[0148] Although Figure 25 The example illustrates the case where each first hole H1 has a circular planar shape, but the planar shape of each first hole H1 is not limited to this.

[0149] Each pixel (PX) can include multiple sub-pixels. Figure 25 The example illustrates a case where each pixel PX comprises three sub-pixels (i.e., first sub-pixel PX1, second sub-pixel PX2, and third sub-pixel PX3), but the number of sub-pixels for each pixel PX is not limited to this. For example, each pixel PX may include more than four sub-pixels.

[0150] Within each pixel PX, sub-pixels PX1, PX2, and PX3 can be arranged along the first direction (X-axis direction). That is, within each pixel PX, the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 can be arranged sequentially along the first direction (X-axis direction).

[0151] The first sub-pixel PX1 refers to the smallest unit emitting light of the first color, the second sub-pixel PX2 refers to the smallest unit emitting light of the second color, and the third sub-pixel PX3 refers to the smallest unit emitting light of the third color. The first color can be red, the second color can be green, and the third color can be blue. For example, the first color can be red light with a center wavelength range of 600nm to 750nm, the second color can be green light with a center wavelength range of 480nm to 560nm, and the third color can be blue light with a center wavelength range of 370nm to 490nm.

[0152] Figure 26a It shows along Figure 25 A cross-sectional view of an example of a display panel, taken by AA'.

[0153] Reference Figure 26aSubpixels PX1, PX2, and PX3 (in) Figure 26a The second sub-pixel PX2 (not shown) may include at least one thin-film transistor ST, at least one capacitor CST, a first electrode 171, a light-emitting element 172, a second electrode 173, a first contact electrode 174, and a second contact electrode 175.

[0154] The substrate SUB can be made of insulating materials such as glass and quartz. The substrate SUB can be a rigid substrate.

[0155] A barrier film BR can be disposed on the first surface of the substrate SUB. The barrier film BR is a membrane used to protect the thin-film transistor ST from moisture that permeates through the moisture-sensitive substrate SUB. The barrier film BR can be composed of multiple inorganic films alternately stacked. For example, the barrier film BR can be composed of alternating layers of silicon oxide (SiO2). x ), silicon nitride (SiN) x Multiple membrane formation of inorganic membranes of at least one of silicon nitride oxide (SiON).

[0156] A semiconductor layer comprising an active layer ACT, a source electrode SE, and a drain electrode DE, of a thin-film transistor ST, can be disposed on the barrier film BR. The semiconductor layer includes polycrystalline silicon, monocrystalline silicon, low-temperature polycrystalline silicon, amorphous silicon, or oxide semiconductor. The source electrode SE and drain electrode DE can be made conductive by doping ions or impurities in the silicon semiconductor or oxide semiconductor. The active layer ACT may overlap with the gate electrode GE in the third direction (Z-axis direction) of the thickness direction of the substrate SUB, and the source electrode SE and drain electrode DE may not overlap with the gate electrode GE in the third direction (Z-axis direction).

[0157] A gate insulating film 130 may be disposed on the active layer ACT, the source electrode SE, and the drain electrode DE. The gate insulating film 130 may include an inorganic film (e.g., silicon oxide (SiO2)). x ), silicon nitride (SiN) x ), silicon nitride oxide (SiON).

[0158] A first gate conductive layer comprising a gate electrode GE of a thin-film transistor ST and a first capacitor electrode CAE1 of a capacitor CST can be disposed on the gate insulating film 130. The gate electrode GE may overlap with the active layer ACT in the third direction (Z-axis direction). The first gate conductive layer may be formed by a single layer or multiple layers composed of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or alloys thereof.

[0159] A first interlayer insulating film 141 may be disposed on the gate electrode GE and the first capacitor electrode CAE1. The first interlayer insulating film 141 may include an inorganic film (e.g., silicon oxide (SiO2)). x ), silicon nitride (SiN) x ), silicon nitride oxide (SiON)).

[0160] A second gate conductive layer, including a second capacitor electrode CAE2 comprising a capacitor CST, may be disposed on the first interlayer insulating film 141. Since the first interlayer insulating film 141 has a predetermined dielectric constant, the capacitor CST can be formed from the first capacitor electrode CAE1, the second capacitor electrode CAE2, and the first interlayer insulating film 141. The second capacitor electrode CAE2 can be formed from a single layer or multiple layers of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or alloys thereof.

[0161] A second interlayer insulating film 142 may be disposed on the second capacitor electrode CAE2. The second interlayer insulating film 142 may include an inorganic film (e.g., silicon oxide (SiO2)). x ), silicon nitride (SiN) x ), silicon nitride oxide (SiON)).

[0162] A data conductive layer including a connection electrode ANDE and a first power supply wiring VL1 can be disposed on the second interlayer insulating film 142. The connection electrode ANDE can be connected to the drain electrode DE through a drain contact hole DCT that exposes the drain electrode DE of the thin-film transistor ST through the gate insulating film 130, the first interlayer insulating film 141, and the second interlayer insulating film 142. Figure 26a The example illustrates the connection of the connection electrode ANDE to the drain electrode DE of the thin-film transistor ST, but the embodiments described herein are not limited to this. For example, the connection electrode ANDE can be connected to the source electrode SE through a source contact hole that exposes the source electrode SE of the thin-film transistor ST through the gate insulating film 130, the first interlayer insulating film 141, and the second interlayer insulating film 142. A first power supply voltage can be applied to the first power supply wiring VL1. The first power supply wiring VL1 can extend in a first direction (X-axis direction), but is not limited thereto. The data conductive layer can be formed as a single layer or multiple layers composed of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or alloys thereof.

[0163] A planarization film 160 can be disposed on the connecting electrode ANDE to planarize the high-low difference caused by the thin-film transistor ST. The planarization film 160 can be formed of an organic film such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin.

[0164] A first electrode 171, a second electrode 173, and an internal dam 191 can be disposed on the planarization film 160.

[0165] The inner dam 191 may be disposed within the opening OA defined by the outer dam 192. The light-emitting element 172 may be disposed between adjacent inner dams 191. The inner dam 191 may include a lower surface in contact with the planarization film 160, an upper surface facing the lower surface, and a side surface between the upper and lower surfaces. The inner dam 191 may have a trapezoidal cross-sectional shape, but is not limited thereto.

[0166] The internal dam 191 can be formed from an organic film such as photosensitive resin, acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin. For example, when the internal dam 191 is formed from a photosensitive resin, it can be a positive photoresist or a negative photoresist.

[0167] The first electrode 171 and the second electrode 173 may be disposed on the planarization film 160 and the internal dam 191. The first electrode 171 and the second electrode 173 may be disposed spaced apart from each other and electrically isolated from each other.

[0168] The first electrode 171 may be disposed on at least one side and the upper surface of the inner dam 191. The first electrode 171 may be connected to the connection electrode ANDE through a pixel contact hole PCT penetrating the planarization film 160. Thus, the first electrode 171 may be electrically connected to the drain electrode DE of the thin-film transistor ST. The pixel contact hole PCT may overlap with the outer dam 192 in the third direction (Z-axis direction).

[0169] The second electrode 173 may be disposed on at least one side and the top surface of the inner dam 191. The second electrode 173 may be connected to the first power wiring VL1 through a common contact hole CCT penetrating the planarization film 160. The common contact hole CCT may overlap with the outer dam 192 in the third direction (Z-axis direction).

[0170] The first electrode 171 and the second electrode 173 may comprise a conductive material with high reflectivity. For example, the first electrode 171 and the second electrode 173 may comprise metals such as silver (Ag), copper (Cu), or aluminum (Al). Thus, light emitted from the light-emitting element 172 that travels toward the first electrode 171 and the second electrode 173 may be reflected by the first electrode 171 and the second electrode 173 and travel toward the upper part of the light-emitting element 172.

[0171] A first insulating film 181 may be disposed on the first electrode 171 and the second electrode 173. The first insulating film 181 may be disposed on a planarization film 160 exposed from being covered by the first electrode 171 and the second electrode 173. The first insulating film 181 may include an inorganic film (e.g., silicon oxide (SiO2)). x ), silicon nitride (SiN) x ), silicon nitride oxide (SiON)).

[0172] An outer dam 192 may be disposed on the first insulating film 181. The outer dam 192 may define an opening OA. The outer dam 192 may not overlap with the inner dam 191. The outer dam 192 may include a lower surface in contact with the first insulating film 181, an upper surface facing the lower surface, and a side surface between the upper and lower surfaces. The outer dam 192 may have a trapezoidal cross-sectional shape, but is not limited thereto.

[0173] The external dam 192 can be formed from an organic film such as photosensitive resin, acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin. For example, when the external dam 192 is formed from a photosensitive resin, it can be a positive photoresist or a negative photoresist.

[0174] The light-emitting element 172 can be disposed on the first insulating film 181. Each light-emitting element 172 can have a rod, wire, tube, or other shape. For example, each light-emitting element 172 can be formed in a cylindrical or rod shape. Alternatively, each light-emitting element 172 can have a polyhedral shape such as a cube or cuboid, or a polygonal prism shape such as a hexagonal prism. Alternatively, each light-emitting element 172 can have a shape that extends in one direction and has a partially inclined outer surface, like a frustum. The length of each light-emitting element 172 can be in the range of 1 μm to 10 μm, or 2 μm to 6 μm, preferably 3 μm to 5 μm. Furthermore, the diameter of each light-emitting element 172 can be in the range of 300 nm to 700 nm, and the aspect ratio of each light-emitting element 172 can be from 1.2 to 100.

[0175] A second insulating film 182 may be disposed on the light-emitting element 172. Furthermore, the second insulating film 182 may be disposed on the outer dam 192. The second insulating film 182 may include an inorganic film (e.g., silicon oxide (SiO2)). x ), silicon nitride (SiN) x ), silicon nitride oxide (SiON)).

[0176] The first contact electrode 174 can be connected to the first electrode 171 through the first contact hole CTT1 penetrating the first insulating film 181. The first contact hole CTT1 can overlap with the inner dam 191 in the third direction (Z-axis direction). The first contact electrode 174 can contact one end of the light-emitting element 172. Thus, one end of the light-emitting element 172 can be electrically connected to the first electrode 171 through the first contact electrode 174. The first contact electrode 174 can be disposed on the second insulating film 182.

[0177] A third insulating film 183 may be disposed on the first contact electrode 174. To electrically separate the first contact electrode 174 from the second contact electrode 175, the third insulating film 183 may be configured to cover the first contact electrode 174. Furthermore, the third insulating film 183 may cover the second insulating film 182 disposed on the outer dam 192. The third insulating film 183 may include an inorganic film (e.g., silicon oxide (SiO2)). x ), silicon nitride (SiN) x ), silicon nitride oxide (SiON)).

[0178] The second contact electrode 175 can be connected to the second electrode 173 through the second contact hole CTT2 penetrating the first insulating film 181. The second contact hole CTT2 can overlap with the inner dam 191 in the third direction (Z-axis direction). The second contact electrode 175 can contact one end of the light-emitting element 172. Thus, one end of the light-emitting element 172 can be electrically connected to the second electrode 173 through the second contact electrode 175. The second contact electrode 175 can be disposed on the third insulating film 183.

[0179] The first contact electrode 174 and the second contact electrode 175 can be made of transparent conductive oxides (TCOs) such as ITO (Indium Tin Oxide) and IZO (Indium Zinc Oxide), which allow light to pass through. This prevents the light emitted from the light-emitting element 172 from being blocked by the first contact electrode 174 and the second contact electrode 175.

[0180] One end of each light-emitting element 172 is electrically connected to the drain electrode DE of the thin-film transistor ST via a first contact electrode 174 and a first electrode 171, and the other end is connected to the first power supply wiring VL1 via a second contact electrode 175 and a second electrode 173. Therefore, each light-emitting element 172 can emit light according to the current flowing from one end to the other.

[0181] A first wavelength conversion layer QDL1 can be configured in the first sub-pixel PX1, a second wavelength conversion layer can be configured in the second sub-pixel PX2, and a transparent insulating film TIL can be configured in the third sub-pixel PX3. The light-emitting elements 172 of each of the first sub-pixels PX1, PX2, and PX3 can emit third light. The third light can be short-wavelength light, such as blue light or ultraviolet light with a center wavelength range of 370 nm to 490 nm.

[0182] The first wavelength conversion layer QDL1 can convert the third light emitted from the light-emitting element 172 of the first sub-pixel PX1 into the first light. The first light can be red light with a center wavelength range of 600nm to 750nm.

[0183] The second wavelength conversion layer can convert the third light emitted from the light-emitting element 172 of the second sub-pixel PX2 into a second light. The second light can be green light with a center wavelength range of 480nm to 560nm.

[0184] The first wavelength conversion layer QDL1 and the second wavelength conversion layer may each include a substrate resin, a wavelength shifter, and a scatterer.

[0185] The base resin can be a material with high light transmittance and excellent dispersion characteristics for wavelength shifters and scatterers. For example, the base resin may include organic materials such as epoxy resins, acrylic resins, calomel resins, or imide resins.

[0186] Wavelength shifters can change or shift the wavelength range of incident light. Wavelength shifters can be quantum dots, quantum rods, or phosphors. The size of the quantum dots in the first wavelength shift layer QDL1 can differ from the size of the quantum dots in the second wavelength shift layer.

[0187] The scatterer can scatter incident light in random directions while keeping the wavelength of light passing through the first wavelength conversion layer QDL1 or the second wavelength conversion layer substantially unchanged. This increases the path length of light passing through the first wavelength conversion layer QDL1 or the second wavelength conversion layer, thus increasing the color conversion efficiency caused by the wavelength shifter. The scatterer can be a light-scattering particle. For example, the scatterer can be a metal oxide particle such as titanium dioxide (TiO2), silicon dioxide (SiO2), zirconium oxide (ZrO2), aluminum oxide (Al2O3), indium oxide (In2O3), zinc oxide (ZnO), or tin oxide (SnO2). Alternatively, the scatterer can be an organic particle such as an acrylic resin or a urethane resin.

[0188] Transparent insulating films (TILs) allow short-wavelength light, such as blue light or ultraviolet light, to pass through uninterruptedly. TILs can be formed from organic films with high transmittance. For example, TILs can be formed from organic films such as photosensitive resins, acrylic resins, epoxy resins, phenolic resins, polyamide resins, and polyimide resins.

[0189] The first wavelength conversion layer QDL1 can be disposed on the second contact electrode 175 and the third insulating film 183 in the first sub-pixel PX1. On the other hand, since the configuration of the second wavelength conversion layer disposed in the second sub-pixel PX2 is substantially the same as that of the first wavelength conversion layer QDL1, the description of the configuration of the second wavelength conversion layer is omitted.

[0190] A low-refractive-index (LRL) film can be deposited on the first wavelength conversion layer (QDL1), the second wavelength conversion layer, and the transparent insulating film (TIL). The refractive index of the LRL film can be lower than the refractive index of the substrate resin of the first wavelength conversion layer (QDL1), the substrate resin of the second wavelength conversion layer, and the refractive index of the transparent insulating film (TIL). The LRL film can be formed from organic films such as photosensitive resin, acrylic resin, epoxy resin, phenolic resin, polyamide resin, and polyimide resin.

[0191] A first color filter CF1, a second color filter, a third color filter CF3, and a black matrix BM can be configured on the low-refractive film LRL.

[0192] The first color filter CF1 may overlap with the first wavelength conversion layer QDL1 in the third direction (Z-axis direction). The first color filter CF1 allows first light (e.g., red-band light) to pass through. Therefore, light of short wavelengths emitted from the light-emitting element 172 of the first sub-pixel PX1 that has not been converted into the first light may not pass through the first color filter CF1. In contrast, the first light converted by the first wavelength conversion layer QDL1 can pass through the first color filter CF1.

[0193] The second color filter may overlap with the second wavelength conversion layer in the third direction (Z-axis direction). The second color filter allows second light (e.g., green band light) to pass through. Therefore, light of short wavelengths emitted from the light-emitting element 172 of the second sub-pixel PX2 that has not been converted into second light may not pass through the second color filter. In contrast, the second light converted by the second wavelength conversion layer can pass through the second color filter.

[0194] The third color filter CF3 can overlap with the transparent insulating film TIL in the third direction (Z-axis direction). The third color filter CF3 allows third light (e.g., blue band light) to pass through. Therefore, short-wavelength light emitted from the light-emitting element 172 of the third sub-pixel PX3 can pass through the third color filter CF3.

[0195] A black matrix BM can be configured between a first color filter CF1, a second color filter, and a third color filter CF3. The black matrix BM can cover the edge positions of the first color filter CF1, the second color filter, and the third color filter CF3. The black matrix BM may include a light-blocking material. In this case, the black matrix BM may include inorganic black pigments such as carbon black or organic black pigments.

[0196] The first hole H1 can penetrate the display panel 100. For example, the first hole H1 can penetrate the substrate SUB, the barrier film BR, the gate insulating film 130, the first interlayer insulating film 141, the second interlayer insulating film 142, the planarization film 160, the first insulating film 181, the outer dam 192, the low refractive index film LRL, and the black matrix BM of the display panel 100.

[0197] In the first aperture H1, the barrier film BR, gate insulating film 130, first interlayer insulating film 141, second interlayer insulating film 142, planarization film 160, first insulating film 181, external dam 192, low refractive index film LRL, and black matrix BM can be removed by an etching process. Therefore, the size of the first aperture H1 can decrease as it moves from the black matrix BM toward the barrier film BR.

[0198] Furthermore, the substrate SUB can be removed through a laser process within the first hole H1. Therefore, the size of the first hole H1 can decrease as it moves from the bottom of the substrate SUB towards the top.

[0199] A first panel lower component 400 may be disposed on the second surface of the substrate SUB. The first panel lower component 400 may include at least one of a light-absorbing component for absorbing light incident from the outside, a buffer component for absorbing impacts from the outside, and a heat dissipation component for effectively releasing heat from the display panel 100.

[0200] The lower part of the first panel 400 may include a second hole H2. The second hole H2 may overlap at least a portion of the first hole H1 in a third direction (Z-axis direction). Figure 26a The example illustrates the case where the second hole H2 completely overlaps with the first hole H1 in the third direction (Z-axis direction).

[0201] The second hole H2 can be formed by removing the lower part of the first panel 400 through a laser process. Although in Figure 26a The illustration shows the second hole H2 decreasing in size as it moves upward from the lower part of the first panel lower component 400, but it is not limited to this. The size of the second hole H2 may increase as it moves upward from the lower part of the first panel lower component 400.

[0202] like Figure 26a As shown, each first hole H1 is formed through the display panel 100, and each second hole H2 is formed through the lower part of the first panel 400. Therefore, the first sound SOD1 and the second sound SOD2 of the first sound generating device 20 and the second sound generating device 30 disposed on the back of the display device 10 can be output to the front surface of the display panel 100 through the first holes H1 and the second holes H2. That is, the first holes H1 and the second holes H2 can be holes that allow sound to pass through. Therefore, even if the first sound generating device 20 and the second sound generating device 30 are located on the back of the display device 10, the first sound SOD1 output from the first sound generating device 20 and the second sound SOD2 output from the second sound generating device 30 can be unblocked by the display panel 100. Therefore, even when the first sound generating device 20 and the second sound generating device 30 are disposed on the back of the display panel 100, it is possible to provide a sound with a sense of presence.

[0203] Figure 26b It shows along Figure 25 Another example of a cross-sectional view of the display panel, taken by AA′.

[0204] Figure 26b Implementation examples and Figure 26aThe difference in the embodiment is that the lower part of the first panel 400 is a lower base that forms the appearance of the back of the display device 10. Figure 26b The main explanation and Figure 26a Differences between the embodiments.

[0205] Reference Figure 26b The lower part 400 of the first panel may be formed of metal or tempered glass. In this case, a gap may exist between the lower part 400 of the first panel and the display panel 100.

[0206] Figure 27a It shows along Figure 25 Another example of a cross-sectional view of the display panel, taken by AA′.

[0207] Figure 27a Implementation examples and Figure 26a The difference in the embodiment is that a first substrate SUB1, a first barrier film BR1, a second substrate SUB2, and a second barrier film BR2 are configured instead of a substrate SUB and a barrier film BR. Figure 27a Omission and Figure 26a The embodiments are described repeatedly.

[0208] Reference Figure 27a The first substrate SUB1 may be made of an organic film such as polyimide. The first substrate SUB1 may be a flexible substrate capable of bending, folding, rolling, etc.

[0209] A first barrier film BR1 may be disposed on the first substrate SUB1. The first barrier film BR1 is a film used to protect the thin-film transistor ST from moisture that may permeate through the moisture-permeable first substrate SUB1. The first barrier film BR1 may be composed of multiple inorganic films alternately stacked. For example, the first barrier film BR1 may be composed of alternating layers of silicon oxide (SiO2). x ), silicon nitride (SiN) x Multiple membrane formation of inorganic membranes of at least one of silicon nitride oxide (SiON).

[0210] A second substrate SUB2 may be disposed on the first barrier film BR1. The second substrate SUB2 may be made of an organic film such as polyimide. The second substrate SUB2 may be a flexible substrate capable of bending, folding, rolling, etc.

[0211] A second barrier film BR2 may be disposed on the second substrate SUB2. The second barrier film BR2 is a film used to protect the thin-film transistor ST from moisture that may permeate through the moisture-permeable second substrate SUB2. The second barrier film BR2 may be composed of multiple inorganic films alternately stacked. For example, the second barrier film BR2 may be composed of alternating layers of silicon oxide (SiO2). x ), silicon nitride (SiN) x Multiple membrane formation of inorganic membranes of at least one of silicon nitride oxide (SiON).

[0212] like Figure 27a As shown, when the first substrate SUB1 and the second substrate SUB2 are made of organic films, the display panel 100 can be a flexible display panel capable of bending, folding, rolling, etc.

[0213] Figure 27b It shows along Figure 25 Another example of a cross-sectional view of the display panel, taken by AA′.

[0214] Figure 27b Implementation examples and Figure 26b The only difference in the embodiment is that a first substrate SUB1, a first barrier film BR1, a second substrate SUB2, and a second barrier film BR2 are configured instead of a substrate SUB and a barrier film BR, therefore the details regarding... Figure 27b Explanation.

[0215] Figure 28a This is an exploded perspective view showing an audio system including a display device according to another embodiment. Figure 28b This is a schematic side view of an audio system including a display device according to another embodiment.

[0216] Figure 28a and Figure 28b Implementation examples and Figure 1a and Figure 1b The difference in the embodiment is that the display device 10 also includes a lower part of the second panel 410. Figure 28a and Figure 28b The main explanation and Figure 1a and Figure 1b Differences between the embodiments.

[0217] Reference Figure 28a and Figure 28bThe second lower panel component 410 may be disposed on one side of the first lower panel component 400. For example, when the display panel 100 is disposed on the front surface of the first lower panel component 400, the second lower panel component 410 may be disposed on the back surface of the first lower panel component 400.

[0218] The lower part of the second panel 410 may include third holes H3. Each third hole H3 may be a hole that passes through the lower part of the second panel 410. The third holes H3 may be arranged in a first direction (X-axis direction) and a second direction (Y-axis direction). That is, the third holes H3 may be arranged in a matrix. Each third hole H3 may overlap with at least one first hole H1 and at least one second hole H2 in a third direction (Z-axis direction). On the other hand, for ease of explanation, a third hole region HA3 is defined in the lower part of the second panel 410, which will be explained later. Figure 29c Detailed explanation will follow.

[0219] The lower component 400 of the first panel can be a heat dissipation component, and the lower component 410 of the second panel can be a lower base. The lower component 400 of the first panel can dissipate heat generated by the display panel 100. For example, the lower component 400 of the first panel may include a metal layer with high thermal conductivity, such as graphite, silver (Ag), copper (Cu), or aluminum (Al). In addition, the lower component 410 of the second panel can form the appearance of the back of the display device 10. For example, the lower component 410 of the second panel may be metal or tempered glass.

[0220] Figures 29a to 29c This is a layout diagram illustrating a first hole in a display panel, a second hole in a lower part of a first panel, and a third hole in a lower part of a second panel, according to an embodiment. Figure 30 It is shown Figures 29a to 29c An example of the overlap of the first hole of the display panel, the second hole of the lower part of the first panel, and the third hole of the lower part of the second panel.

[0221] Figures 29a to 29c and Figure 30 Implementation examples and Figure 2 and Figure 3 The difference in the embodiment is the addition of a third hole H3. Figures 29a to 29c and Figure 30 The main explanation and Figure 2 and Figure 3 Differences between the embodiments.

[0222] Reference Figures 29a to 29c and Figure 30 Each third hole H3 can have a polygonal planar shape. Figures 29a to 29c and Figure 30The illustration shows the case where each third hole H3 has a rectangular planar shape, but is not limited to this. Each third hole H3 may have a circular or elliptical planar shape. Alternatively, it should be noted that the planar shape of each third hole H3 may have other shapes within the scope of modification that can be made by those skilled in the art. The planar shape of each third hole H3 may differ from the planar shape of each first hole H1 and each second hole H2.

[0223] The size of each third hole H3 can be larger than the size of each first hole H1 and each second hole H2. That is, the area of ​​each third hole H3 can be larger than the area of ​​each first hole H1 and each second hole H2.

[0224] The maximum length of each third hole H3 in the first direction (X-axis direction) and the minimum distance between adjacent third holes H3 in the first direction (X-axis direction) can be defined as "g×(a+c)". Furthermore, the maximum length of each third hole H3 in the second direction (Y-axis direction) and the minimum distance between adjacent third holes H3 in the second direction (Y-axis direction) can be defined as "h×(b+d)". Here, "g" can be a positive integer greater than "e", and "h" can be a positive integer greater than "f". Figures 29a to 29c and Figure 30 The example shows the cases where "g" and "h" are 2.

[0225] That is, the maximum length 2×(a+c) of each third hole H3 in the first direction (X-axis direction) and the minimum distance 2×(a+c) between adjacent third holes H3 in the first direction (X-axis direction) can be defined as twice the sum of the maximum length a of each first hole H1 in the first direction (X-axis direction) and the minimum distance c between adjacent first holes H1 in the first direction (X-axis direction). Furthermore, the length 2×(b+d) of each third hole H3 in the second direction (Y-axis direction) and the minimum distance 2×(b+d) between adjacent third holes H3 in the second direction (Y-axis direction) can be defined as twice the sum of the maximum length b of each first hole H1 in the second direction (Y-axis direction) and the minimum distance d between adjacent first holes H1 in the second direction (Y-axis direction).

[0226] In this case, even if the display panel 100 including the first hole H1 is not aligned with the lower part of the first panel 400 including the second hole H2, each of the second holes H2 can overlap with at least one first hole H1 in the third direction (Z-axis direction). Figure 30 The example illustrates the case where each second hole H2 overlaps with a first hole H1 and each third hole H3 overlaps with a second hole H2.

[0227] That is, each third hole H3 can overlap with at least one first hole H1 and at least one second hole H2 in the third direction (Z-axis direction). Therefore, even if the first sound generating device 20 and the second sound generating device 30 are located on the back of the display device 10, the first sound SOD1 output from the first sound generating device 20 and the second sound SOD2 output from the second sound generating device 30 can be output towards the front surface of the display device 10 without being blocked by the display panel 100, the lower part of the first panel 400 and the lower part of the second panel 410, respectively, through the third hole H3 of the lower part of the second panel 410, the second hole H2 of the lower part of the first panel 400 and the first hole H1 of the display panel 100. Therefore, even when the first sound generating device 20 and the second sound generating device 30 are arranged on the back of the display panel 100, a sound with a sense of presence can still be provided.

[0228] Figure 31 This is an exploded perspective view showing an audio system including a display device according to another embodiment.

[0229] Figure 31 Implementation examples and Figure 1a The difference in the embodiment is that the display panel 100 includes a plurality of display panels 101, 102, 103, 104 and a bonding member 105. Figure 31 The main explanation and Figure 1a Differences between the embodiments.

[0230] Reference Figure 31 The display panel 100 may be a tile-type display panel comprising multiple display panels 101, 102, 103, and 104. Figure 31 The illustration shows a case where the display panel 100 includes four display panels 101, 102, 103, and 104, but the embodiments described herein are not limited to this.

[0231] Multiple display panels 101, 102, 103, and 104 can be arranged in a grid pattern, but are not limited to this. Multiple display panels 101, 102, 103, and 104 can be connected in a first direction (X-axis direction) or a second direction (Y-axis direction), thereby allowing the display panel 100 to have a specific shape.

[0232] exist Figure 31 The illustration shows multiple display panels 101, 102, 103, and 104 having the same size as each other, but the embodiments described herein are not limited to this. The multiple display panels 101, 102, 103, and 104 may have different sizes.

[0233] The multiple display panels 101, 102, 103, and 104 can each be a rectangle including both a long side and a short side. The multiple display panels 101, 102, 103, and 104 can be configured by connecting their long or short sides to each other.

[0234] Multiple display panels 101, 102, 103, and 104 may each include a first hole H1 and a pad hole PDH (see reference). Figure 32 The first hole H1 and the pad hole PDH can be holes that penetrate the display panel 100.

[0235] The first hole H1 can be configured in the display area of ​​multiple display panels 101, 102, 103, and 104 respectively (see reference). Figure 1a In the DA), the first holes H1 can be arranged in the first direction (X-axis direction) and the second direction (Y-axis direction). That is, the first holes H1 can be arranged in a matrix form.

[0236] The pad-hole PDH can be configured in the non-display area of ​​multiple display panels 101, 102, 103, and 104 respectively (see reference). Figure 1a In the NDA. The pad-hole PDHs can be arranged in either a first direction (X-axis direction) or a second direction (Y-axis direction). The pad-hole PDHs can be configured adjacent to one edge of the display panel 100 in multiple display panels 101, 102, 103, and 104, respectively. For example, as Figure 31 As shown, the pad holes PDH of the first display panel 101 and the second display panel 102 can be arranged adjacent to the upper edge of the display panel 100, while the pad holes PDH of the third display panel 103 and the fourth display panel 104 can be arranged adjacent to the lower edge of the display panel 100.

[0237] Multiple display panels 101, 102, 103, and 104 can be connected to each other via a connecting member 105. The connecting member 105 can be an adhesive member with adhesive strength.

[0238] Figure 32 It is shown Figure 31 The rear layout diagram of the display pads and pad holes, display driving circuit and circuit board of the first display panel. Figure 33 It shows along Figure 32 A cross-sectional view of an example of the display panel captured by BB'.

[0239] Reference Figure 32 and Figure 33Connection electrodes CE can be configured in each pad hole PDH of the first display panel 101. The connection electrodes CE can be connected to the routing wiring RL disposed on the gate insulating film 130 through the pad holes PDH. The connection electrodes CE can be connected to the connection wiring CL, and the connection wiring CL can be connected to the display pad DP.

[0240] The connection electrode CE, connection wiring CL, and display pad DP can be disposed on the back side of the substrate SUB. The connection electrode CE, connection wiring CL, and display pad DP can be formed as a single unit. That is, the connection electrode CE, connection wiring CL, and display pad DP can be formed from the same material.

[0241] Each display pad DP can be connected to the circuit board 300' via an adhesive film ACF. Thus, each routing trace RL of the display panel 100 can be electrically connected to the display driving circuit 200' of the circuit board 300' via the connecting electrode CE, the connecting trace CL, and the display pad DP. The adhesive film ACF can be anisotropic conductive film.

[0242] Figure 34 This is a layout diagram illustrating the first hole and pad hole of the first display panel and the second hole of the lower part of the first panel according to an embodiment. Figure 35 This is an example diagram illustrating the overlap of a first hole and a pad hole in a first display panel, and a second hole in a lower component of the first panel, according to an embodiment.

[0243] Figure 34 and Figure 35 Implementation examples and Figure 2 and Figure 3 The difference in the embodiment is that the first display panel 101 includes not only the first hole H1 but also the pad hole PDH. Figure 34 and Figure 35 The main explanation and Figure 2 and Figure 3 Differences between the embodiments.

[0244] Reference Figure 34 and Figure 35 The first hole H1 and the pad hole PDH can be formed by removing the substrate SUB using the same laser process. Therefore, the first hole H1 and the pad hole PDH can have substantially the same size. That is, the first hole H1 and the pad hole PDH can have substantially the same area.

[0245] Each pad hole (PDH) can be a hole for configuring connection electrodes (CE) of connection routing lines (RL) and connection lines (CL), wherein the routing lines (RL) are disposed on the front surface of the substrate (SUB), and the connection lines (CL) are disposed on the back surface of the substrate (SUB). Therefore, each pad hole (PDH) does not overlap with the second hole (H2) in the third direction (Z-axis direction).
